I think most people in history have found the idea of eternal life to be appealing. The alternative is that we die at some point or at least cease to exist, which is unappealing to most people.
<p>
The idea of living a long time is appealing as long as we imagine that we're in good health, never get old, and things are going our way. We expect that in God's kingdom when we've received imperishable resurrection bodies, and there's no more sickness, pain, death, sadness, etc., that we'll be pretty happy. But it's hard to imagine that we'd be happy in the long term. I mean <i>really</i> long term because if we're talking about never-ending life, then it will go on for trillions and trillions and trillions and . . . of years.
<p>
While many people might find a very long life of health and prosperity to be appealing, the idea of <i>eternal</i> life, no matter how wonderful conditions might be, is frightening. It will become a hell merely becasue of the length of it.
<p>
I remember when I was younger I used to answer this objection by imagining that there's no end to God's creativity in keeping us entertained and happy forever. A God who is all knowing and all powerful will never fail to keep life fresh and interesting. But even if there were a theoretical limit to the kinds of things and situations God could create to keep us amused, he could simply use his omnipotence to zap us with contentment, and he could do this continuously throughout eternity. In that case, our joy wouldn't even require external stimuli.
<p>
Some people answer this objection by pointing to the timelessness of heaaven. If time doesn't even exist, then there's no way to ever get bored over a long period of time. First of all, I doubt it's true that there's no time in heaven. Second, and more importantly, I believe in a physical resurrection, and that certainly entails a temporal existence.
<p>
These days, however, I see our joy as consisting more in experiencing and apprehending God himself than in God zapping us with joy or constantly creating new good experiences for us to have. Imagine something you've seen that was magical and wonderful, like a total eclipse, a scene from _Life of Pie_, a magnificent work of art, a mountain, a lightening storm, the Milkyway Galaxy on a dark night away from the city. Or imagine things you would like to see in real life that have been drempt up in fiction, like a million fairies all simultaneously taking flight in the dark, or whatever. There are many exquisite things that have been seen or imagined that would be a wonder to behold, and that's just visual perception. We're also moved by stories, music, physical touch, love, friendships, and donuts.
<p>
Any of these things, no matter how wonderful we can imagine them to be, would probably become boring after trillions and trillions of years. But I don't think God would be. God is not only the most beautiful, wonderful, holy, sublime, and great being that exists, but he's the most glorious being that <i>could</i> exist. I don't think we have the capacity to fully imagine what such a being is like. He exhausts even our capacity to appreciate him.
<p>
What I suspect is that God is so layered and so multi-faceted that there is no end to the glory that we might experience and apprehend when we are in his presence. I suspect that God's glory (everything that is true and wonderful about him) is inexhaustible. I don't think we have words to describe him fully or concepts to imagine him fully. We have a tiny glimps of him through what he has revealed to us by way of Scripture, reason, and intuition. I think eternal life will be never-ending joy because of being in the presence of God. It is God himself, the worship of him, and the enjoying him forever that will wipe out any possibility of eternal life becoming tiresome or boring. We will never exhaust the glory of God.
<p>
I suspect this may be hard for some people to believe because you're trying to imagine the unimaginable. If you can't even imagine a being so wonderful and glorious that merely being in his presence would be sufficient to make etneral life a never-ending joy, then it's hard to imagine that it's even possible.
<p>
I think it's not only possible, but it's the reality we live in. The answer to questions like, "What is the meaning/purpose of life?" can be found in Yahweh - the God of Abraham, Isaac, Jacob, and Jesus. Everything exists for him and because of him, and in him all things hold together. He is the alpha and the omega, the beginning and the end. It's all about him. It makes sense that Paul would say, "Therefore, whether you eat or drink, or whatewver you do, do all things for the glory of God" (1 Corinthians 10:31). That's what it's all about. Even Christians, myself included, get distracted and fail to live up to the lofty goal of allowing our desire for the glory of God to be the motive behind everything we do, but I think ultimately that is where we will find our greatest joy in eternity.

It looks like blogging isn't as popular as it used to be. YouTubing has become more popular. I still prefer blogs over YouTube videos.
<p>
If you're trying to improve your knowledge and understanding about the various topics surrounding Christianity and Christian apologetics, you really should be blogging or YouTubing. It is possible to read a whole book with your mind in neutral and remember almost nothing of what you read. But if you have to explain it to somebody else, then you have to learn it. If you are introduced to a new idea in a book you read, it's a good idea to blog on it because blogging on it forces you to understand the idea. You may find that in the process of writing the blog, you have to go back over what you read a few times as a reminder. Engaging with the ideas in this way will make it stick in a way that it wouldn't have if all you did was read about it.
<p>
Blogging has the added benefit of allowing you to engage with other people on the topics you are learning about. If you're lucky enough to have people comment on your blog posts, you'll be forced to think even harder about the subject because you'll want to respond to those comments in a thoughtful way. Even if you don't respond, you'll at least get to see a different take on the subject, and you'll get some feedback that reveals how well you understood (or misunderstood) the topic and how well you were able to communicate your thoughts on it. All of this engagement will make the information you're learning about stick even better. It will also improve your ability to communicate clearly.
<p>
If I'm reading a book that I plan to write about later, I take notes. Taking notes also makes the ideas stick. It's crazy, but I remember quotes from books I read a couple of decades ago because I took notes and because I used the quotes in things I wrote later on. When I take notes, I include both quotes and summaries. Quotes are useful if you plan to write reviews or use the book or article as a source later on, but writing summaries is really useful for both understanding and memory. You'll want your summaries to be accurate, so you'll be forced to read carefully enough to understand what you are reading. If you can accurately summarize a passage you are reading, you should understand it well enough to explain it to somebody else.
<p>
I encourage you to blog or find some medium that involves writing. I know a lot of people are reluctant to blog because they think, "Who am I to pontificate on this subject or tell other people how things are as if I know something?" I had that same thought when I started this blog. But the purpose of this blog wasn't primarily to inform the world. It was to hone my own noetic structure--to express myself in the hopes of getting feedback and pushback so that I could improve intellectually. You don't have to put yourself out as an expert on a subject to justify writing about it. It's just a blog after all. You can use your blog to bounce ideas off of other people.
<p>
But blogging is also a release when you have a lot of pent up thought and imagination running through your head after reading something, and you're just dying to get it off your chest.
<p>
With that being said, you don't have to be an expert on a topic before your opinion is valuable. People often have interesting things to say about topics that are new to them. Everybody is entitled to having a point of view, however ill-informed it might be. If you had to be an expert on a topic before you were justified in expressing a point of view, there would be no reason for most of us to ever have interesting conversations with each other about these things. I'm often curious what people think about a topic when they are <i>not</i> experts. I'm often curious what people's initial impressions are upon first hearing about something or having it explained to them. A lot of my blog posts are just that--intitial impressions upon first being introduced to something.
<p>
YouTubing may be useful in the same way that blogging is, but I really think writing is better. If the way you YouTube involves writing scripts, then I suppose that's just as good since you are writing.

Somebody recently asked me what Jehovah's Witnesses believe. I used to know a lot about Jehovah's Witnesses. I read several of their books, a ton of their magazine articles, and I dialogued with them on beliefnet and in person. But it has been many years since I've read any of their material or even talked much with them. I've forgotten a lot. But I wrote an email explaining as best I can remember what the big ticket items were with Jehovah's Witnesses, focusing especially on areas where they differ from other Christians.
<p>
The best way to learn what Jehovah's Witnesses believe is to get their little book, <i>Knowledge That Leads to Everlasting Life</i>. Or it used to be anyway. They put out a newer book that contains pretty much the same information called <i>What Does the Bible Really Teach?</i>. Either of these books will give you the basics, and they're both pretty short. I've always thought that if you want to learn what other religions, deminations, sects, or whatever teach, it's best to get it from the horse's mouth. People do tend to misrepresent others, especially when they disagree with them. It's not always intentional, but it happens.
<p>
For those who just want the basics at a glance, here is the email I wrote. If there are any Jehovah's Witnesses reading this who think I got anything wrong, left anything important out, or just want to elaborate on what I wrote, please leave a comment. Without further ado. . .
<p>
You've asked me a few times now what Jehovah's Witnesses believe, so I thought I'd write it all out for you as best I can remember. I used to be pretty heavy on Jehovah's Witnesses, but it's been a long time. This is mostly about how Jehovah's Witnesses are distinguished from every other Christian sect.
<p>
1. JW's believe God chose their organization to be his mouthpiece in the end times. They believe their organization, which is run by the Governing Body of Jehovah's Witnesses, was appointed by Jesus around 1918 to be the "faithful and discreet slave" mentioned in Matthew 24 to "give them their food at the proper time." They believe their organization is God's "sole channel of communication," and that one must be part of their organization in order to receive salvation. The governing body publishes their material through the Watchtower Bible and Tract Society. They believe these publications contain the "food at the proper time." They study this literature on a weekly basis. When talking to each other, they refer to each other as being "in the truth" because they believe it is only through their organization that God is revealing his truth to mankind. They do not believe that one can simply study the Bible and arrive at the truth; one must study the Bible through the lense of their literature.
<p>
2. JW's believe that the second coming of Jesus happened in 1914. Whereas most Christians believe Jesus will physically return to earth, JW's believe the meaning of the second coming is that Jesus will be present in kingdom power. This means Jesus actually was enthroned as King in 1914. This isn't a physical return to earth. Rather, it's the beginning of Christ's kingdom. They also believe the beginning of WWI was the result of Jesus being enthroned in heaven. His enthronement caused a war between Satan and God's angels, which somehow manifested itself in WWI.
<p>
3. Since JW's believe they are part of the heavenly kingdom, they maintain a degree of separation from the political affairs of the world. They don't vote or take political office. Many of them avoid any type of government work, but that is mostly a matter of individual conscience. They also don't join the military or engage in any type of warfare. It isn't because they are necessarily pacifists, but because they believe they are to maintain a separation from worldly politics.
<p>
4. Whereas most Christians believe God is a trinity, JW's believe God is a unity. In their view, Jehovah created Jesus. Then Jesus created the rest of the cosmos. Jesus was the only thing Jehovah created directly. Everything else was created through Jesus. Since Jesus is created, he is not part of a trinity. He is subordinate to the Father, and only the Father is Jehovah. Prior to the incarnation, Jesus was Michael the Archangel. Whereas most Christians believe the Holy Spirit is one of the persons of the Trinity, Jehovah's Witnesses do not believe the Holy Spirit is a person at all. In their view, the Holy Spirit is more like a force. They sometimes refer to it as "God's active force."
<p>
5. It is very important to JW's to use God's proper name, which is Jehovah. Jehovah is an Anglicised version of the divine name, which is transliterated from Hebrew as YHWH. There are no vowels in the old Hebrew. The Hebrew name for God is sometimes called the tetragrammaton. While Jehovah shows up in the King James Version, most Christians these days use Yahweh as God's proper name. Nobody actually knows how God's name was originally pronounced because Jews stopped pronouncing it out loud a long time ago, and because there are no vowels in ancient Hebrew.
<p>
6. JW's do not believe we survive as disembodied souls when we die. When we die, we essentially cease to exist. Jehovah remembers us perfectly and uses his memory of us as a blueprint for reconstructing us at the resurrection. Almost all Christians believe in a resurrection at the end of the age. Whereas a lot of Christian understand a "soul" to be something like a ghost, JW's understand it as referring to a living person. When God breathed life into Adam, Adam became a living soul. According to JW's, our spirit is an animating force that causes us to be alive. It is not something capable of conscious disembodied existence.
<p>
7. Jesus did not physically rise from the dead. When Jesus died, he ceased to exist. The resurrection of Jesus involved him being recreated again as a spirit person in heaven. The body that lay in the tomb was disposed of by Jehovah, so the empty tomb really had nothing to do with Jesus rising from the dead. Jehovah got rid of the body in order to avoid confusion. The appearances of Jesus after his resurrection were similar to how angels appeared to Abraham and Lot. Jesus manifested himself temporarily in a physical way, but he was not actually physical.
<p>
8. JW's believe there are two classes of Christians--those with a heavenly hope, and those with an earthly hope. Those who have the heavenly hope are made up of 144,000 people. Most of them were chosen during the first century, but some of them were chosen during the 20th century. The resurrection of the 144,000 began when Jesus was enthroned in 1914. Since that time, whenever a member of the 144,000 dies, they are immediately resurrected in heaven as spirit beings. They do not have a physical resurrection. For everybody else, they will be physically resurrected on earth at the end of the age.
<p>
9. At some point, Jesus is going to overthrow all the governments on earth and establish God's kingdom on earth. This event is called Armageddon, the eschaton, or the end of the age. Once Jesus takes over, he will rule earth for 1000 years. The 144,000 will reign with him as kings and priests. The rest of Jehovah's Witnesses will be resurrected around the beginning of the escahton (my memory is a little fuzzy about the timing). During the 1000 year reign, Satan will be bound so that he has no influence in the world anymore. The earth will be restored to paradise conditions. I think those of us who were not Jehovah's Witnesses will be resurrected sometime during the 1000 year reign, possibly toward the end of it. Again, my memory is fuzzy. Around the end of the 1000 year reign, Satan will be released for one last hurrah. He will wage a war against Jesus, and he will lose. Once he loses, he and everybody who followed him will be snuffed out of existence. Everybody who is left will have eternal life on a paradise earth, except for the 144,000. I'm not sure what they do after the 1000 year reign. Once Jesus has destroyed Satan along with everybody else who didn't take Jesus' side, Jesus will hand the kingdom back over to Jehovah.
<p>
10. It is very important for JW's to maintain a degree of separation from the world. They don't want to engage in any activity that might have any hint of paganism, which is why they don't celebrate any birthdays or holidays. The only thing they celebrate is their annual memorial service, which is where they commemorate the death and resurrection of Jesus. During this service, only those who think they are members of the 144,000 partake of communion. The rest just watch.
<p>
11. There are some other minor issues that JW's tend to make a big deal about. For example, they think Jesus died on a simple upright pole rather than a cross shaped structure. This is another area where they just want to avoid anything that might smack of paganism. They think the cross is a pagan symbol. Another minor issue that is very important to them concerns blood. They believe the command to abstain from consuming blood applies to blood transfusion. So not only will they not eat blood, but they will not take it into their body through blood transfusions either.
<p>
There are a lot of other things that distinguish Jehovah's Witnesses, but these are all the big ticket items. At least the ones that I can remember.
<p>
12. Oh yeah, and they also have their own Bible translation. It's called The New World Translation. They believe it is superior because whereas most English translations substitute "LORD" for the divine name, theirs uses "Jehovah." Most people think it's a terrible biased translation, though.

While motive-mongering is a big pet peeve of mine, I find it hard not to speculate about the motives of other people. I pretty much always keep those thoughts to myself, though.
<p>
I've complained about pro choice people engaging in motive mongering before ("<a href="https://philochristos.blogspot.com/2023/02/have-pro-choicers-given-up.html">Have pro-choicers given up?</a>"). The go-to tactic of pro-choicers these days is to say that what's <i>really</i> motivating pro-lifers is not a concern for the unborn, but just the desire to control women. After all, pro-lifers allegedly only care about people before they are born. Once they are born, they no longer care.
<p>
Besides being wrong about the motives of pro-lifers, these speculations are irrelevant. They amount to ad hominem fallacies. They suffer from irrelevance because they have nothing to say about the morality of abortion. They neither refute any pro-life arguments nor defend any pro-choice arguments. By themselves, they tell you absolutely nothing about whether or not it's okay to have an abortion.
<p>
While it bothers me how much weight pro-choicers seem to think their irrelevant motive-mongering carries, it bothers me a whole lot more when I see pro-lifers engaging in the same behavior. I've seen pro-lifers attribute some of the worst motives to pro-choicers. For example, they'll say people only take the pro-choice position so they can endulge their sexual lusts without consequences. Or they'll liken the pro-choice denial of the personhood of the unborn to the dehumanization of other races, the motive being to discriminate against them and deny them their rights.
<p>
One reason it bothers me so much when pro-lifers engage in motive-mongering is because I'd like for those who are on my side to be above all that silliness. But it bothers me even more because I think it does damage to our message. We should want to persuade people, not insult them. People tend to stop listening to you when you attack them personally.
<p>
The major problem with motive-mongering, besides being irrelevant, is that when you speculate about somebody else's motives, the other person always knows better than you do whether or not you are right. Each of us has direct and immediate access to the content of our own mental states in a way that nobody else does. If you are wrong about the motives you attribute to another person, then they know it. And if you keep insisting on it, then they also know that you're a fool. Why should they have any future interest in anything you have to say once you have exposed yourself as being a fool?
<p>
Even if you happen to be right about their motives, the fact that you are trying to shame them will make them resistant to being honest with themselves about their motives. People will <a href="https://philochristos.blogspot.com/2020/02/deluding-ourselves.html">delude themselves</a> by <a href="https://philochristos.blogspot.com/2022/07/reasons-vs-justifications-vs-excuses-vs.html">rationalizing</a> in order to <a href="https://philochristos.blogspot.com/2005/04/crazy-things-people-do-to-avoid.html">avoid ethical pain</a> until they convince themselves that their motives are pure, at which time, they will still think you are a fool.
<p>
Can we please stop the motive-mongering? It doesn't do anything but give you the illusion of moral superiority while simultaneously causing you to lose all credibility with the person you are trying to persuade.
</p>

There are some things we have in common with computers. When we reason, we use logic. There are also logic circuits built into computers. I remember learning about these in my first engineering class in college. There's AND, NAND, OR, NOR, and so on. There are specific outputs given specific inputs. They work in a way that's not unlike deductive logic.
<p>
Recently, I was reading through some comments (I don't even remember where), and somebody described what computers do as reasoning. While I can see why I person might think of it that way, that is not how I think about reasoning. To me, reasoning is a conscious process. If you don't have consciousness, then you don't have reason.
<p>
A computer with logic gates behaves mechanistically and blindly. They don't actually think. When we reason, we do not just passively process information. We draw conclusions from premises by mentally "seeing" that the conclusion follows from the premises. There's an intuition involved in reasoning because it is by intuition that we recognize the logical relationship between various statements and propositions. In order to reason, we have to process and understand the meaning of the information we receive in a way that computers don't.
<p>
I am tempted to say the difference between what we do when we reason and what computers do when they process information using logic gates is even more apparent when we move away from math and deductive reasoning and more into inductive reasoning. I'm not sure, though. On the one hand, the conclusions of inductive arguments are not logically required in the same way the conclusions of deductive arguments are. On the other hand, there are algorithms that allow computers to form generalizations. On the third hand, those algorithms have to be able to be reduced to deductive processes. Otherwise, you wouldn't be able to code them. I'm not sure that's true when people reason inductively. It might be, though.
<p>
Often when we reason inductively, a lot of that reasoning is subconscious. For example, when we have negative experiences, we automatically anticipate the same negative experience under similar circumstances. We start avoiding those circumstances because of this anticipation, but we don't have to explicitly think anything like, "Every time I have been faced with these circumstances in the past, it has resulted in unpleasantness; therefore, I should expect the next time I run up against these circumstances, it will also result in unpleasantness; therefore, I should avoid those circumstances." Any baby or animal can learn through experience that fire is hot, for example, without having to go through a set of propositions and a conclusion. If humans come to conclusions through subconscious processes, and we consider that "reasoning," then is consciousness really necessary for reasoning?
<p>
I still say yes. Everything about this subconscious way of coming to a conclusion still requires consciousness. There's the conscious experience of feeling the heat from the fire, the conscious experience of dreading future contact with the fire, etc. Any conclusion we reach results in a belief, and a belief is something that requires consciousness. A belief does not have to be expressed in words. A dog probably has no idea how to express the thought, "Fire is hot," but he still knows it's true. Language isn't necessary for belief or thought, but consciousness certainly is.
<p>
That is not to say we have to constantly be thinking about or giving mental attention to a belief in order to have a belief. If I were presently consumed with thoughts about pizza, and diamonds were the furthest thing from my mind, I would still have a belief that diamonds were hard. You don't have to be presently thinking about something in order to have a belief about it. A belief can be stored like a memory where it can be recalled, but it doesn't have to be right in front of our mental gaze.
<p>
I know I've rambled a bit. I'm just thinking out loud. The bottom line is that I don't think computers reason, at least not in the usual sense of the word. While there are similarities between what computers do and what minds do, I think the major difference is in whether the process is blind and mechanistic, like a computer, or whether it involves intuitively "seeing," as well as understanding, like a mind. The way we draw conclusions by thinking things through is not how computers arrive at outputs, even when those outputs are expressed in words.

By "relationships," I mean family, friends, and romantic relationships. Close human connection in general is what I'm talking about.
<p>
I used to know a woman who thought it was a sign of weakness if somebody felt like they needed other people. I always disagreed with that. We are a social species. The fact that we are a social species is a strength, not a weakness. It's the reason we developed language, why our brains got so powerful, how we were able to develop civilizations, etc. Since we are a social species we rely on each other, not only in a cooperative way, but in an emotional way, too.
<p>
I haven't always had this opinion, but it has gotten stronger the older I've gotten. Ironically, the older I get, the less I feel the need to have a lot of social interaction. But I still believe social interaction is very important for our mental, emotional, and physical well-being.
<p>
This is true not only for extroverts, but for introverts like myself, too. In my case, I have always been happy with a small circle of close friends. I don't enjoy large gatherings of people I barely know. But since I become more content with solitude the older I get, I actually have to make a conscious effort to maintain personal relationships. If you're married and have a family, it probably requires more effort to get a little alone time than to invest in your relationships, but if you're single and live alone, like me, then it requires effort to be social.
<p>
Anyway, this video from Veritasium came up on my feed today, and I wanted to share it with you. It's about this 50 year on-going study about what makes people happy. It confirms a lot of what I've come to believe about the importance of social connection, friendship, and even marriage. I think it is a grave mistake to consider one's need to have companionship to be a weakness. It is not a weakness. It's simply the way we were designed. People who have more fulfilling relationships tend to have better health, better mental acuity, they live longer, and they are happier. It's worth it to put in the effort. I'm not just preaching to you, either. I'm preaching to myself. I haven't done that great of a job working at, pursuing, and nurturing relationships, especially since the pandemic.

Earlier this year I started thinking about getting a car with better acceleration. It can be stressful trying to merge onto an interstate when your car has no get up and go. Having a car without good acceleration is frustrating sometimes.
<p>
I discovered that EV's (particularly Teslas) have really good acceleration. This sent me down a rabbit hole learning about EV's and the EV market. Now I want to express an opinion based on what I've learned.
<p>
One of the major appeals of EV's is that they don't spit out pollutants or carbon dioxide. They're environmentally "clean." While that is true, it is offset by the fact that you have to charge them. That electricity has to come from somewhere. Most of the power in the electrical grid comes from burning fossil fuels. Due to the second law of thermodynamics, the more energy conversions you have between the source and the use, the less efficiency you're going to have. If you have to convert fuel to heat, then to mechanical energy in a turbine, then electrical energy in a generator, then send it out in the electrical distribution system, raising and lowering voltages through transformers, then store it as chemical energy in your battery, then convert it into mechanical energy in the car's motor, you're losing a lot more efficiency than if you're just burning fuel in your engine, turning it to mechanical energy, and making your car go. So probably you're burning more fossil fuels using an electric car than you are a gas powered car.
<p>
Also, it requires a lot of heavy machinery to mine the lithium, cobalt, and other minerals required to make those batteries, and that also burns fossil fuels. And I'm not sure how environmentally friendly those batteries are and whether disposing of them will be an issue in the future.
<p>
Another issue with EV's is that they don't have the range of gas powered cars. I think this is a problem that can be fixed as battery technology improves. Right now, though, it causes what people are calling "range anxiety."
<p>
Infrastructure is also a big problem, but this is only a temporary inconvenience that can be fixed with time. There weren't gas stations everywhere when gas powered cars were invented either. At the time, though, range anxiety is a consequence of both the low range of EV's and the paucity of charging stations, especially in rural areas.
<p>
It takes longer to charge a car than it does to fill your car with gas. That's going to be a real pain for people who are driving long distances. I think improvements can be made, but it's always going to be an issue. Maybe it'll just be something we adjust to.
<p>
Most people who own EV's will probably charge their car over night at home. That won't work for people who live in apartments, though. Europe wants to ban gas powered cars altogether. If they do, apartments are going to have to supply their parking lots with charging stations. A lot of people in the U.S. want to ban gas powered cars, too. That will either create a huge headache for people who live in apartments, or it will cause a headache for people who build apartments. Rents will have to go up if they're going to be forced to provide charging stations.
<p>
Most people buy used cars. I've never bought a new car. EV's have a major disadvantage when it comes to used cars, though. As the battery ages, the range of the car is diminished. When the battery wears out, the car becomes totaled because it costs more to replace the battery than the car is worth. Nobody is going to want to buy used EV's because the battery will already have diminished capacity. You can't keep a used EV running indefinitely just by taking really good care of it like you can with a gas powered car. Used gas powered cars don't lose range as they get older either. They just have more maintenance issues.
<p>
I question whether EV's will be good to have in snowstorms. If you're stuck somewhere because of a blizzard, you're probably better off being stuck in a gas powered car. At least then you can keep it running and stay warm. I'm not sure how long an EV would last in those conditions. I also don't know how much running the air conditioner or heater affects range. I've heard the batteries don't work as well when it's really cold or really hot. Heat is a bigger issue than cold for me personally, since I'm from Texas, but I'm just thinking about the rest of the world, especially our neighbors to the north.
<p>
Running out of gas in the middle of nowhere is an issue, but it's a bigger issue with an EV. With an EV, you're more likely to run out of charge because charging stations are fewer and farther between, and you don't get as much range anyway. With a gas car, somebody can bring you a gallon or two of gas so you can get to the next gas station. With an electric car, somebody will have to come along with a way to charge your battery. I don't know if anything like that even exists yet. You'd probably just have to get your car towed.
<p>
The batteries used in EV's require lithium, which has to be mined. They also use cobalt and other materials that have to be mined. These materials aren't everywhere, which means there has to be a lot of cooperation between different countries to make the EV world work. If we all go EV-only, this could create problems. Political disputes could make it easier for some countries to impose sanctions on other countries. From what I understand the U.S. has a lot of its own lithium, but I think most of the cobalt comes from the Republic of Congo. I don't know how abundant the materials necessary to make batteries are. If batteries are to improve, I imagine we might use materials we're not necessarily using now, which makes the future somewhat unpredictable. A lot of us Americans don't mind importing goods from other countries, but we're uneasy about being <i>dependent</i> on other countries, like we are to a large extent on oil and gas. We don't <i>have</i> to be dependent on other countries for oil and gas. We just tend to prefer dependence to drilling and refining in our own country. But if we go all electric, we may <i>have</i> to be dependent on other countries in case we don't have all the raw materials to make the batteries we're going to need.
<p>
As far as I know, Tesla is the only company that has been able to make EV's profitable. With them lowering their prices all the time, it makes it very hard for anybody else to compete. Companies like Rivian may make good EV's, but if they can't turn a profit, they're going to go under. Telsa may become a monopoly. That's not so bad if you're an investor. Actually, I think there's an EV company in China that may be profitable. I'm not sure.
<p>
There are some advantages to EV's, though. Charging your car is probably less expensive than buying gas. If you just use your car to drive around town, and you can charge it at home while you sleep, you can avoiding going to gas stations and charging stations altogether. Also, there's the good acceleration. They also don't have as many moving parts, so the maintenance isn't going to be as frequent or costly, at least until the battery wears out. On the other hand, I've heard it can sometimes be a nightmare trying to get your EV serviced by Tesla, and normal auto mechanics can't help you.
<p>
I think EV's probably are going to be our future in spite of all these drawbacks. I suspect we'll just adjust. I mean they're still better than a horse and buggy. I'm going to keep driving gas powered cars, though, because at the moment, I don't think EV's are worth it. That is unless you live in a city, don't travel long distances, own a house, and maybe a second car that runs on gas. Then it might be worth it.

Food snobbery is the enemy of innovation. With the exception of fresh fruit plucked right off the tree, every dish was invented at some point. Tacos, pizza, and sushi were all created by assembling different ingredients in a way that nature would never have produced if left to itself.
<p>
With that in mind I do not understand people who turn up their nose, roll their eyes, and say things like, "That's not <i>authentic</i> Mexican food," or, "You put <i>what</i> on your pizza?" or, "The Japanese don't put the wasabi in the soy sauce." I don't care if some dish isn't traditional or authentic. I care if it's good. I just want to enjoy my food. We can all thank the Italians for inventing the pizza, but New Yorkers made it better. Imagine a world in which food snobs insisted the rest of the world never improve upon the pizza.
<p>
There are a lot of dishes that have become their own thing, but they were inspired by something that came before. The Hawaiian's came up with spam musubi, which was inspired by sushi. Sushi snobs must've been having conniptions when that happened. Spam musubi is pretty good, though, especially when you use seasoned Korean nori.
<p>
I like avocado in my sushi, I like pineapple on my pizza, and I like tomatoes in my tacos. One of my favourite things in the world to eat is fajitas. Thank goodness the man who invented fajitas didn't have a food snob looking over his shoulder scolding him because it wasn't authentic Mexican food.

I was just watching a <a href="https://www.youtube.com/watch?v=433tAfO4dbA">new video by Sabine Hossenfelder</a> about the many worlds interpretation of quantum mechanics, and I had an idea for an argument against Many Worlds. This argument is based on my flimsy understanding of physics, so take it with a grain of salt.
<p>
The many worlds interpretation is based on the idea that the wave function of a particle is real, and it never collapses. The wave function describes the movement of subatomic particles (like electrons) over time, and it gives you a probability distribution of where you should expect to find the particle if you were to try to measure it. You can observe the wave-like nature of particles using the double slit experiment. If you shoot a laser of photons or a beam of electrons through a double slit, it produces an interference pattern on the other side, which is what you would expect if there were a wave.
<p>
But the individual photons or electrons hit the wall in one particular spot. In the Copenhagen interpretation, this is understood to mean that the wave of probability collapsed to one particular result. Whereas the probability of where an electron <i>might</i> hit the wall is described by the wave function, it actually only hits in that one spot.
<p>
In the many worlds interpretation, though, the wave function doesn't collapse. Instead, the electron actually does hit the wall in each spot where it's possible it could have hit. This is possible because for each possibility, there is a branching universe in which it happens. We observe it hitting the wall in one spot because we're only in one of those branches at a time.
<p>
Since there's an interference pattern on the wall, that means there will be more branching universes in which the electron hits within the peaks of the probability distribution than in the valleys.
<p>
Since there is a branching universe with every possible outcome of every subatomic particle (including photons) in the universe, there are an unfathomable number of universes being generated each moment. For every possible scenario that could happen, given the laws of quantum mechanics, there is a branching universe in which it <i>does</i> happen.
<p>
If you take the many worlds interpetation seriously, you can have a lot of fun thinking about the other branching worlds that exist. In some of them, you are wildly successful because you made all the right decisions. In others, you've already been eaten by a bear. In several of them, you are Batman.
<p>
It's crazier than that, though. It also means that what we might usually think of as a miracle could happen purely by natural means. If the subatomic particles of a dead person could take a path resulting in them being rearranged in such a way as to cause the person to be alive, then a person could rise from the dead purely by natural means. It wouldn't be a miracle, but it would look like a miracle. It would be a wildly unlikely scenario, but since the location of each particle necessary to make the person alive exists somewhere in the probability distribution, and the wave function never collapses, then there are definitely worlds in which dead people come to life. Maybe this is one of them.
<p>
Now, let me get to the argument I came up with. If the wave function never collapses, and there's a different world for every possible outcome of every particle in the universe, then we should expect there to be a lot more universes in which the subatomic particles all randomly move in such a way as to kill us. I mean if my body kind of disintegrates because every particle went the wrong way, I would die. It seems more likely that given all the possibilities, there are more possibilities in which I die than in which I continue to live. Since I'm still alive, does this cast doubt on many worlds?
<p>
One response might be to invoke an observer selection effect. I can only observe worlds in which I live, so the fact that I'm not dead doesn't tell me anything. I would have to be in one of the rare worlds in which I live to be thinking about this.
<p>
But what about everybody else? Granted, I must be alive in a world in which I'm thinking about this, the same thing doesn't apply to everybody else. Shouldn't I observe a world in which I'm alive, but people are dropping like flies all around me? The fact that they aren't suggests that many worlds is probably not true.
<p>
As I was watching Sabine's video, I saw what might be the clue to a flaw in this argument. She made a distinction between a path integral and a measurement. She said the many worlds interpretation is about measurement outcomes, not path integrals. My argument kind of assumes the path integrals are spread out along a probability distribution.
<p>
But it seems to me that path integrals and measurement outcomes are related. If an electron hits the wall at a specific location, doesn't that tell you something about its path integral? It had to travel along some path to get there.
<p>
I don't know. I suspect there's something wrong with my argument, but I'm not sure what it is. Maybe the problem is in misunderstanding what a measurement even means. I take measurement to refer to causal interaction. When an electron hits the wall, that's essentially a measurement because it collapses to one specific result. So if the subatomic particles in our bodies are interacting with each other, they should be collapsing to specific locations all the time.
<p>
But I don't know. Electrons in orbitals seem to fill the orbitals. The whole reason they occupy spread out space, rather than specific points, is because they have wave functions. As I mentioned in a <a href="https://philochristos.blogspot.com/2023/07/the-normalizability-objection-to-fine.html">different post</a>, the size of an electron is defined by its Compton wavelength. If they are waves, they can only exist in specific energy levels, just like how a guitar string can vibrate in different specific harmonics, but not just any-ole-where. An electron can only exist in specific orbitals, but not between them any-ole-where. So if electrons are in their wave-like states around all the atoms in my body, rather than some specific location, that seems to suggest that their wave functions are not collapsing, and they are not being "measured." If so, that would undermine my whole argument. Maybe that's why I'm wrong. I don't know, though.
<p>
Anywho, check out Sabine's video, but don't read the comment section. There's a lot of nonsense going on there. And yes, I do see the irony in that statement.
<p>
<b>Edit (11/5/2023):</b> I have decided this argument is completely flawed. If what I argued here were true, you wouldn't even need there to be a multiverse before you should expect people to be dropping like flies all around you. On the many worlds interpretation, many worlds exist, but you only observe one. The one you observe is every bit as random as the many others you <i>might</i> have observed. So even without all those worlds actually existing, people should be dropping like flies all around you because your path through life takes you through many random outcomes. If the mere randomness of the outcomes is enough to put our lives into jeopardy, then your life would be just as much in jeopardy under the Copenhagen interpretation. If we have nothing to fear from random quantum events on the Copenhagen interpretation, then we should have nothing to fear from the randomness of which world you happen to live in under the many worlds interpretation.

I've been thinking for a long time about writing a fan fiction for Superman. In the fanfiction, Superman comes to the realization that he could save more lives if he went into the medical field than he could using his superior strength and speed. By using his x-ray vision, he can quickly and efficiently diagnose people with cancer, blood clots, and all kinds of other things. He would become an expert surgeon, too, knowing exactly where the problem lies and being able to see it clearly. So he goes to medical school.
<p>
In the past, I've used fan fictions to fulfill wishes I've had about stories. In the case of Superman, I've come up with all kinds of things he could do that he hasn't done in other Superman stories. Here's a few of them:
<p>
1. He could go camping anywhere in Alaska or Yellowstone for as long as he wants and not worry about being eaten by a bear.
<p>
2. He could walk all the way across Africa, from the north down to the southern tip, and never worry about being eaten by a lion, gored by a buffalo, or killed by a warlord. Mosquitos couldn't even harm him.
<p>
3. He could fly to various moons, planets, and astroids in the solar system to gather samples for scientists. Or he could take video and do other kinds of research that are difficult or impossible for us to do now with our technology and the money it takes to do it.
<p>
4. He could perform repairs and upgrades to satelites and space telescopes. He could deliver satelites and telescopes to space for a lot less than what it costs with rockets. And since he's not limited by the rocket equation, engineers would have a lot more flexibility in what they could put into space. They could make an even bigger space telescope. Superman could take it to space and oversee its deployment to make sure everything goes smoothly.
<p>
5. He could transport materials and help build a space station on the moon, Mars, or just someplace in earth's orbit. I've always thought it would be cool if we could build spaceships in space. Superman could deliver the materials and supplies.
<p>
6. He could provide propulsion for a spaceship to take humans to Mars or wherever. It wouldn't matter how big the spaceship was, either. That means you could cover the spaceship in shielding to protect the astronauts from radiation without having to worry about the added weight. Plus, Superman could get them there faster. He could possibly provide them with artificial gravity by accelerating at a constant rate for half the trip, then decelerating at a constant rate for the rest of the trip. Or he could just spin it.
<p>
7. He could find your keys or pretty much anything you've lost using his x-ray vision.
<p>
8. He could be a blacksmith or a bladesmith. He could heat the steel up with his laser beam eyes and sculpt the hot steel with his bare hands. He wouldn't need a forge, an anvil, or hammers. He could sculpt hot steel like it was a piece of clay.
<p>
There are just all kinds of things Superman could do. He could be a construction worker and elminate the need for cranes or heavy equipment in a lot of cases. He could help build bridges or underground tunnels. There's no reason for Superman to ever be unemployed unless he wants to be.
<p>
What would you have Superman do? Or what would you do if you were Superman?

<b>A note from the author (11/5/2023):</b> <i>I originally wrote this back in September. I took it down because I was afraid it might be too negative and sound like I was attacking other apologists. Truth be told, I was a little annoyed when I wrote it. But I just re-read it and decided it's worth posting after all. So here you go.</i>
<p>
Knowledge of <i>what is</i> is different than knowledge of <i>how to</i>. Unfortunately, there are a lot of people who want to make a living by giving advice to other people on <i>how to</i> without having a lot practical experience.
<p>
If you want advice from somebody about how to invest in the stock market, you should talk to somebody who has been successfully investing in the stock market for a long time. You shouldn't go to somebody who has only read a lot of books about investing or taken college classes on investing but hasn't actually put that knowledge into practice.
<p>
Would you want to learn how to do brain surgery from somebody who had never performed a brain surgery but who had only read about it or came up with what he thought was a great idea? Would you want fishing advice from somebody who has only watched fishing shows on TV but has never gone fishing?
<p>
If you want parenting advice, you should go to somebody who has succesfully raised good, moral, well-adjusted, and successful children. I don't care if somebody has a PhD in psychology. If they haven't successfully raised children of their own, then their knowledge is only theoretical. It doesn't necessarily mean they have nothing to contribute, but they are not the best person to go to for advice, especially if you have access to somebody with real experience who has been successful.
<p>
Speaking of which, <a href="https://www.youtube.com/@MAVENTRUTHGOODNESSBEAUTY/videos">Brett and Erin Kunkle</a> are the real deal.
<p>
The internet is full of people who want to give life advice, relationship advice, and all sorts of advice, but haven't lived long enough or had enough experience to really be qualified. Just today I stumbled across a 25 year old kid who called himself a life coach. That is ridiculous. He may have gained some insight from people who mentored him or from the short life he has lived, and maybe he has something to offer, but nobody should go to somebody that age for life advice. He doesn't have enough life experience to justify putting himself in that kind of position. If you want a life coach, go to somebody in their 60's or older, who has already lived out the majority of their lives. And go to somebody who has done so succesfully--who has had good relationships, done well in life, and is thriving.
<p>
Everything I've said so far is leading up to the real point I want to make in this blog post. There are a lot of people who are trying to make a living by being professional apologists. Apologetics is about defending your worldview, your beliefs, or whatever cause you want to promote. There are some apologists who actually do that, but many of them don't. Instead, they make their living by teaching apologetics to others. Their audience is other Christians, and they insulate themselves from real criticism.
<p>
The problem is that unless they have real world experience defending their beliefs and interacting with people who disagree with them, and unless they have had success in doing so, they aren't qualified to teach others how to defend their faith. A lot of people think they are qualified to teach because they've read a lot of books, watched a lot of lectures and debates, and they have developed a lot of theoretical knowledge. Theoretical knowledge is important, but it's not adequate to being a good apologist. Being a good apologist is something you learn by being in the trenches, dialoging with people, finding out what's pursuasive and what isn't, getting feedback from critics, etc. There's a trial and error aspect to communicating. As you go back and forth with people, you find out where your weaknesses lie. You may have weaknesses in communicating clearly, or you may have weaknesses in the content of your defense. You may have all the right answers and all the best arguments which you learned from books, but you are unable to have a productive conversation with people because they won't listen to you, or you can't control your emotions, you lack the people skills necessary to keep people interested, or you dont know how to communicate your knowledge in an accessible way.
<p>
This is something I've been thinking about for a few years. Since I have social anxiety, I don't engage in apologetics much in real life. Most of my interactions happen on the internet. They have happened on this blog, other people's blogs, and on YouTube, but the vast majority of it has happened on discussion forums. A few years ago, I was pretty active on Reddit. The longer I was there, the more I started noticing that I was mostly all alone. There were a few Christians trying to do apologetics on there, but I didn't see many people who were really good at it--who knew there stuff, were articulate, could respond well to objections, and could engage hostile people with grace and maturity. I began to wonder, "Where is everybody?" That's when I started thinking about this. There are a lot of people who presume to teach others how to defend their faith, but they aren't in the trenches doing it themselves. They are doing apologetics without an opponent.
<p>
I believe you can learn something from anybody. Everybody knows something, and most people know something most other people don't. But if you are going to <i>seek out</i> people to learn from, seek out people who know what they're talking about. If you want to learn how to defend your faith, learn from people who actually defend their faith, who listen to what their critics say, and who respond to their critics. And seek out, especially, people who are successful at it.
<p>
That last part is the hard to define, though. How do we measure success? At what point can we say that our apologetic method is effective? Success and effectiveness can be measured in different ways. A Christian can be considered successful if they were obedient in sharing the gospel even if nobody converts. Success is measured by their obedience and in overcoming whatever fear and anxiety they had about sharing the gospel. Success can also be measured by whether you got your point across in a way the other person could understand, even if the other person doesn't agree. Success can be measured by whether you maintained civility when dialoging with somebody about a controversial and emotionally charged subject. In the case of formal debates, success can be measured by your win rate. Yes, as crass as that may sound, that's how you measure success in debating. When it comes to apologetics, the purpose is to persuade, and the primary way we ought to measure the effectiveness of our apologetic is by whether it successfully persuades others.
<p>
By that criteria we might as well admit that most of us are not effective at all. In that last 25 years, there have been maybe a handful of times when somebody has contacted me and told me I changed their mind about something. But aside from somebody telling you that, you probably have no idea how many people you have influenced. People can be influenced who were just on the sidelines watching.
<p>
I have been talking so far about effectiveness in "doing apologetics," and by "doing apologetics," I mean communicating reasons to think your point of view is true to other people and responding to their questions and objections. Doing apologetics well requires having a good vocabulary, having good communication skills, having good people skills, and having some degree of cleverness. However, you can't even get off the ground if you don't have some knowledge. By stressing practical knowledge, I do not at all mean to diminish the necessity of theoretical knowledge.
<p>
In the case of theoretical knowledge, though, you should be mindful of who you go to for information. Do you go to your dentist for advice on how to fix your car? Do you go to your mechanic for dietary advice? Do you go to a doctor for legal advice or a lawyer for medical advice? If you want good theoretical knowledge, you should go to people who are experts in the subject you are interested in.
<p>
Apologetics is a multisciplinary field. It draws from other fields like history, science, philosophy, and theology. There are some apologists who are experts in one of these fields. William Lane Craig, for example, is an expert in philosophy. But most professional apologists are not experts in any particular field, and they quite frequently butcher some of the subjects they address in their literature and talks. I'm not saying you shouldn't bother reading apologetics literature at all. I think you should if you want to get into apologetics. What I am saying, rather, is that you should not rely solely on apologists for your information about science, philosophy, history, or theology. If you want to master some subject in apologetics that involves cosmology, then you should read literature from actual cosmologists. If you want to master historical arguments about Jesus, you should read literature from professional New Testament historians.
<p>
You shouldn't just read literature from people who agree with you either. If you were to get a PhD in physics, you'd be forced to read literature from people who subscribe to string theory and people who reject string theory. If you want to get a PhD in ethics, you'll be forced to read literature from people who subscribe to consequentialism and people who reject consequentialism. Part of becoming educated in a particular subject involves hearing all the voices of all the people who are experts in that field. If you want to become a good competent apologist, you should strive to become as well-equipped as you can on whatever subject in apologetics you want to specialize in. It's good to know a little bit about everything, but realistically, you're never going to be an expert on everything.
<p>
My advice is only aimed at those who want to excel at apologetics. If you want to dip your toe in, sure, just read <a href="https://philochristos.blogspot.com/2020/11/reading-for-beginners-in-christian.html">a few apologetics books</a>. But if you want to become a <i>good</i> apologist, you need to be mindful about who you learn from. When it comes to theoretical knowledge, go to people who are experts in their field. Think of apologetics books as introductions to various topics, not as authoritative sources. When it comes to practical knowledge, go to people who are actually engaging in apologetics and doing it well, not people who are simply teaching other people to do apologetics without doing it themselves. And by "doing it," I don't mean just writing blog posts or books or making youtube videos. I mean interacting with people who disagree with them, subjecting their arguments to scrutiny. And if you decide you want to become a professional apologist (i.e. make a living at it), please don't become somebody who does apologetics without an opponent. If you do, you will be doing yourself and your audience a disservice.

Yes, probably. You can go now.
<p>
Seriously, though. . .the book of Acts says that Paul performed multiple miracles, but it's easy to see why somebody might be skeptical. However, there are some things Paul wrote in his own letters that aren't as easy to deny.
<p>
I'm not just talking about a situation in which Paul says he did a miracle or that he witnessed a miracle. That, too, would be easy to deny. We could just say Paul tells tall tales. Instead, I'm talking about a situation in which Paul claims to have done a miracle that his audience witnessed.
<p>
For example, in 2 Corinthians 12, Paul was defending his apostleship. He talked about these grand visions he had and how God gave him a thorn in his flesh to keep him humble. He says that he is not inferior to other apostles, then follows it by saying, "The distinguishing marks of a true apostle were performed among you with all perseverance, by signs, wonders, and miracles" (2 Corinthians 12:12).
<p>
That is pretty crazy, if you think about it. Whereas anybody might just make up a story they hope their audience will believe, Paul is reminding his audience of something they are in a position to know about. He's claiming they saw it themselves. They would know whether that was true or not. If it wasn't, we should expect them to think, "What on earth is he talking about?" And we wouldn't expect Paul to say something like that if he knew they knew it wasn't true.
<p>
If Paul was lying, then that's some major gaslighting.
<p>
If Paul is telling the truth, as he almost certainly was, then what sort of an event might he have been talking about? One possibility is that Paul's signs and wonders are no different than what we see in a lot of charismatic churches today. There's little evidence that anything miraculous is taking place, but people seem to think the Holy Spirit is healing people, casting out demons, knocking them down, making them speak in tongues, etc. There's a lot of silliness and hysteria that goes on in some charismatic churches. There's probably nothing miraculous going on most of the time, but people do believe there is. Maybe something like that is what Paul is referring to.
<p>
That seems unlikely, though. In the case of these charismatic churches, the hysteria and belief people have about these faith healers and word-faith preachers is the result of them already being converted to the worldview, and them having their expectations up. It's different in Paul's case because it looks like, from other passages, that it was common for Paul to use signs and wonders in his evangelism. He was in the process of converting people who did not already believe.
<p>
There are a handful of places where Paul reminds his audiences that he is not a good speaker. He expects his audience to already know this. He attributes their conversion to the power of Holy Spirit rather than the pursuasive power of his words. For example, in his first letter to the Thessalonians, he said:
<p>
<blockquote>"For our gospel did not come to you in word only, but also in power and in the Holy Spirit and with full conviction; just as you know what kind of men we proved to be among you for your sakes" ~1 Thessalonians 1:5</blockquote>
<p>
I used to read that and think Paul was just talking about the inner work of the Holy Spirit in changing people's hearts so that they would be receptive to Paul's message. But when looking at it in light of 2 Corinthians 12, I'm not so sure if that's what he meant. Consider what he said to the Corinthians in an earlier letter.
<p>
<blockquote>"And when I came to you, brothers and sisters, I did not come as someone superior in speaking ability or wisdom, as I proclaimed to you the testimony of God. For I determined to know nothing among you except Jesus Christ, and Him crucified. I also was with you in weakness and fear, and in great trembling, and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, so that your faith would not rest on the wisdom of mankind, but on the power of God." ~1 Corinthians 2:2-5</blockquote>
<p>
In this passage, Paul says he came to them "in demonstration of the Spirit and of power," but in 2 Corinthians he says, speaking to the same audience, that he performed signs, wonders, and miracles (2 Corinthians 12:12). It's possible he's talking about two dististinct events, but I doubt it. I suspect when Paul refers to the "demonstration of the Spirit and of power" that accompanied his speech, he was talking about the signs and wonders he performed for the Corinthians.
<p>
When Paul wrote his letter to the Romans, he had not yet visited Rome. He was writing to a church he did not plant. But he explains his mission to gentiles in that letter. He says,
<p>
<blockquote>For I will not presume to speak of anything except what Christ has accomplished through me, resulting in the obedience of the Gentiles by word and deed, in the power of signs and wonders, in the power of the Spirit; so that from Jerusalem and all around as far as Illyricum I have fully preached the gospel of Christ." ~Romans 15:18-19</blockquote>
<p>
It looks like it was normal for Paul to present the gospel to people both in word and in demonstrations of the Spirit that manifest themselves in signs and wonders. That's a pretty bold thing for Paul to say, and it should be a little startling for us to read.
<p>
There is always room for doubt, but considering the fact that Paul claims on multiple occasions to different audiences that his preaching of the gospel was regularly accompanied by signs and wonders which were instrumental in the conversion of his audience, and he even says these thing to the very people who were the recipients of the message and the signs, that it almost definitely happened. Add to that Luke's account of Paul's miracles in Acts, and this strikes me as good evidence that Paul performed miracles. At the very least, if you're bent on being skeptical, Paul performed what he and his audience <i>took</i> to be miracles.

Last Thursdayism is the idea that all of us and the world around us just came into existence last Thursday. We have what appear to be memories of a past that pre-dates last Thursday because when we came into existence, our brains were formed in such a way as to contain those false memories.
<p>
Last Thursdayism isn't actually a belief a certain segment of the population believes in. It's mainly just used as a thought experiment to illustrate certain points. I've invoked it to illustrate how it's possible to know some things without being able to prove them. I can't prove that anything happened before last Thursday, but I'm nevertheless justified in thinking it did. However fallible my memory may be, it still justifies me in believing certain things about the past.
<p>
Last Thursdaism can't be disproved by some appeal to evidence because the world would look exactly the same whether it's true or false. Our memories would be exactly the same, too.
<p>
This thought experiment rests on the mere possibility of Last Thursdaism. A person might object to Last Thursdaism on the basis of something else they know by intuition--it's impossible for something to come from nothing. If it's impossible for something to come from nothing, then Last Thursdaism isn't possible.
<p>
Does this undermine the thought experiment? I don't think it does. First, I think Last Thursdaism can be offered as a logical possibility. Creation out of nothing isn't a logical impossibility. It's more of a metaphysical impossibility. So Last Thursdaism can be logically possible without being metaphysically possible.
<p>
Second, it depends on what you're using Last Thursdaism to illustrate. I use it to illustrate the fact that we can know some things without having to prove them. A person might object to my illustration by saying, "We know there's a past because creation out of nothing is impossible, so things couldn't have just popped into being fully formed." But the reality is that we all know there's a past, and our intuition about creation out of nothing has nothing to do with it. We don't reason from that intuition to our belief in the past. That makes the impossibility of creation out of nothing irrelevant to the illustration.
<p>
Third, as I've said in some previous posts, I don't think thought experiments necessarily have to describe possible states of affairs in order to do some work for us. Even if we grant that Last Thursdaism isn't possible (whether physically, logically, or metaphysically doesn't matter), we can imagine it being possible, and we can use that imaginary state of affairs to illustrate our point. It's similar to how Aristotle imagined a state of affairs in which the law of non-contradiction didn't hold in order to illustrate why we all know it does. His scenario wasn't possible, but it gets the point across.

I'm always a little reluctant to respond to the worst arguments when there are good arguments to respond to. I don't want to be accused of going after low-hanging fruit. But sometimes, like today, I'm motivated to respond to an argument because it's popular, and not because it's worth responding to on its own merits.
<p>
Today, I'm going to respond to an argument that has come up multiple times in conversations I've had and conversations I've witnessed about fine-tuning. It came up one time in a meet up group I was a part of. At the time, I thought the guy was joking, and maybe he was, but a lot of people are serious about it.
<p>
Fine-tuning is the idea that the free parameters in our physics equations have to fall within extremely narrow ranges before life can even be possible in our universe. Since there is such a narrow range of values the constants of nature have to fall into so the univere can be life-permitting, the probability that our universe would be life-permitting is extremely small.
<p>
The objection that sometimes comes up is that the probability that our universe is life-permitting is 100% because if it wasn't life-permitting, there wouldn't be any life, yet here we are. I don't mean to insult anybody, but people do make this argument seriously and think it's a good response to fine-tuning.
<p>
The problem with the argument is that it's looking at the wrong probability. The question for fine-tuning isn't whether our universe actually <i>is</i> life-permitting. Of course it is! The probability is 100% that our universe is life-permitting. The question, rather, is what the probability is that our universe (or any universe) <i>would be</i> life-permitting if it didn't have to be.
<p>
Let me use a lottery analogy. Since there are a large number of possible outcomes, there's a very small probability that any given ticket will have the right numbers. That's why you have such a small chance of winning the lottery. But suppose I won the lottery, and I said to my friend, "Wow! What are the chances that I would win the lottery?" And my friend said, "It's 100% probable because you won." We would know immediately that my friend was confused because I wasn't asking what the chances are that I <i>did</i> win the lottery, but what the chances are that I <i>would</i> win the lottery given all the possible outcomes? The answer to my real question is whatever the odds were that any given ticket would have the winning numbers.
<p>
The same thing is true with fine-tuning. The question isn't, "What are the odds that our universe is life-permitting?" but "What are the odds that our universe <i>would be</i> life permitting?" What are the chances that <i>any</i> random universe would be life-permitting given that there's a large range of possible values the constants could take and only a small life-permitting range? That's the question.
<p>
This seems so obvious to me that I wonder, of all the people who raise this objection to fine tuning, how many of them are being serious and how many are joking? I would likely think they were all joking if it weren't for the fact that people will dig their heels in about it and others will congratulate them for bringing it up. This might be the silliest argument I know against fine-tuning.

<b>How I make the dough</b>
<p>
I used Tipo 00 pizza flour. The brand I like is called Anna Napoletana, but I'm sure other stuff works. It's finer than all purpose flour, and it has a higher protein/glucose content. If you can't find it, you can use bread flour. That's the next best thing. It's a little more coarse, but it has about the same protein content. As a last resort, you can use all purpose flour. I like King Arthur's. Here are the proportions I use (these are called baker's percentages):
<p>
<blockquote>
Flour - 100%<br>
water - 65%<br>
salt - 2%<br>
active dry yeast - 1%
</blockquote>
<p>
I use these proportions because it makes it easy to remember, easy to calculate in my head, and it works. I have gone as high as 70% on the water content. It makes a good dough, but it's more difficult to work with. I usually make enough dough for two pizzas at a time. Or, if I'm making pizzas for some other people, I'll make enough for four. I'm just going to tell you what the measurements are for one pizza. You can just multiply this yourself if you want to make more.
<p>
<blockquote>
Flour - 210 grams<br>
water - 137 grams<br>
salt - 4 or 5 grams<br>
active dry yeast - 2 grams
</blockquote>
<p>
It's a really good idea to get a digital scale so you can get these proportions exact. It also allows you to experiment by varying them a little and keeping track of what you did.
<p>
<blockquote>
EDIT (8/8/2023): What the hey, I'll just do the math for you. . .
<p>
<i>Two pizzas</i><br>
Flour - 420 grams<br>
water - 273 grams<br>
salt - 8 or 9 grams<br>
active dry yeast - 4 grams and maybe a smidge more
<p>
<i>Three pizzas</i><br>
Flour - 630 grams<br>
water - 410 grams<br>
salt - 13 grams<br>
active dry yeast - 6 or 7 grams
<p>
<i>Four pizzas</i><br>
Flour - 840 grams<br>
water - 546 grams<br>
salt - 17 grams<br>
active dry yeast - 8 or 9 grams
<p>
</blockquote>
<p>
I mix that up in a bowl, then turn it out on the counter. I use a bowl scraper to get everything out. Then I mix it the rest of the way with my hands. As soon as it starts getting just a little sticky, I cover it with the bowl and walk away for 10 minutes. Then I come back and knead it until I get tired of kneading it. That's usually about five to ten minutes. Ideally, it will stop being sticky after a while. Do not add flour to it. If you want, you can let it rest another ten minutes and come back to kneading it. It should be less sticky that way. But kneading it ought to make it less sticky eventually.
<p>
Once it's fairly smooth and not so sticky anymore, put it in the bowl, cover it with plastic wrap, and stick it in the oven with the oven light on. Leave it in there until it doubles in size. It may take an hour or two, depending on how cold it is in your place. If your yeast isn't good anymore, it may not rise much at all. I keep my yeast in the refrigerator so it stays good longer.
<p>
Once it has doubled in size, take it out, and fold it over a few times, and turn it into a ball by tucking it under itself, stretching it. Then stick it back in the bowl, cover it, and stick it back in the oven until it doubles again.
<p>
This time, make your dough balls. First, put a little olive oil in a decent sized bowl. You can use tupperware if you want, but I prefer a bowl. Cut up the dough if you made enough for more than one pizza. Tuck it under itself over and over, stretching the top. There are YouTube videos showing how to do this part. It's easier show than to explain. Put the dough smooth size down in the olive oil, spin it around a little so the olive oil gets all over that side, then flip it over and spin it a little more. Put some plastic wrap over that, but not too tight because you want it to have room to rise a little.
<p>
Leave that out a few minutes - no more than 5 or 10 - then stick it in the refrigerator. Leave it in there for two days. You can use it after one day or even three or four days, but it's best after two days.
<p>
<b>How I make the sauce</b>
<p>
I get one of those big cans of San Marzano whole peeled tomatoes. You can fish the tomatoes out with your hand if you want to, but I just pour the whole thing into a mixing bowl and use it all. You can use a hand blender if you want. I prefer not to because it's too easy to over do it. If you over do it, it'll be too runny. I prefer to squeeze the tomatoes with my hand and just mush them up. I want it to be slightly chunky, and doing it with my hand gets just the right consistency.
<p>
We want to add some ingredients to it for flavour. I don't usually measure my ingredients, but I guess I'll give you some measurements to get you in the ballpark. There's lots of flexibility in these proportions, though.
<p>
Olive oil - No more than a quarter of a cup. Probably a little less.<br>
Sea salt - I'm not really sure how much. Maybe 10 grams.<br>
Oregano - I use that dry stuff you buy in a shaker and just about cover the top of my sauce. It's a lot.<br>
Garlic - I use two or three cloves. I don't know what you call it, but I rub them against this little grater thingy.<br>
Red pepper - I'm not really sure how much red pepper I put in there. Just take a guess, then taste it and see if you like it.
<p>
I told you I was going to give you some measurements, but I didn't really do that, did I? Sorry. It's subjective, but it's unlikely you'll create a disaster.
<p>
Anywho, put that in some tupperware and put it in the refrigerator.
<p>
I've complained about the fact that this makes so much sauce it commits me to having to eat nothing but pizza for two weeks. It's enough sauce for about ten pizzas. It has been suggested to me that I freeze it in little zip lock snack bags so I can take them out one at a time to use it. I've tried that, and it always ruins the sauce. It makes it runny, and it's just never as good. You can try it, though.
<p>
<b>How I put my pizza together</b>
<p>
On the day I make the pizza, I take the dough out of the refrigerator about two hours before it's time to make it. I sprinkle a little flour on top of it, and some flour on the counter or cutting board. I scoop it out with my bowl scraper, and gently put it smooth side down on the flour I sprinkled on the counter. I don't put any flour on the rough side which should be facing up. I cover it with a big bowl and let it sit for two hours, or thereabouts.
<p>
At least an hour before I'm ready to make the pizza, I turn my oven on to the highest temperature it will go. Where I used to live, that was 500ºF. I've made pizza at other people's houses, though, and theirs only got up to 450ºF, which was a bummer. Anyway, the point here is to heat up your pizza stone. You need to have a pizza stone.
<p>
Now that the oven is hot, and the dough has come to room temperature and risen a little, it's time to put the pizza together.
<p>
You're going to need a pizza peel. I put a dusting of flour on the pizza peel so the pizza doesn't stick. A lot of people like to use semonila, and that's probably better. You can use corn meal if you want, but I'm not crazy about that. The idea is just to make sure the pizza doesn't stick to the peel.
<p>
Now we need to stretch the dough. Again, this is easier to show than to explain, so watch some YouTube videos. Basically, I use my finger tips to push down the middle of the dough and out toward the edge. I leave the edges fluffy. Do not use a rolling pin like some idiots do because you'll destroy your crust. Once the middle is pushed down, and the puffy perimeter is pretty even, I pick it up and begin to stretch it. I lay it over one hand, pull a little with the other, then rotate it, and pull again. As it grows, I'll put my knuckles under it and stretch it out a little more. If I'm feeling it, I'll toss it in the air and spin it.
<p>
Once you're done playing with the dough, put it on the pizza peel. Now stetch it by pushing it, pulling it, or whatever you have to do to get it nice and round. If you dusted your peel like you should have, this step should be easy.
<p>
Now take a big plastic spoon, scoop some pizza sauce, and pour it in the middle. Use the back of the spoon to spread it. Start in the middle, and make circles, getting bigger and bigger each time you go all the way around until you've spread the sauce pretty evenly over the pizza. A lot of people use too much sauce when they're just learning to make pizza. Again, I can't really explain how much to use. It's easier to show.
<p>
Considering how much I say that, maybe I just need to make a YouTube video.
<p>
Anyway, pick up the pizza peel and shake it back and forth a little bit to make sure the pizza slides without sticking. If it doesn't, lift it close to where it's not sliding and throw some flour under there, and try again. Once you get it sliding well, slide it onto that pizza stone. You can really mess up here. Don't freak out if you mess up the first time. After you do it a few times, it gets easy. You can make it perfectly round.
<p>
Keep that oven light on and watch it. When the edges just barely start to change colour, take it out using the pizza peel.
<p>
At this point, you can put whatever you want on it. I almost always put some parmesan on it first. Sometimes, I just put fresh mozzarella on it and nothing more. If you get shredded mozzarella from the grocery store, it's not going to be that great. Fresh mozerella is awesome possum. Other times, I'll cut up some ham and put it on there, and I might put some pineapple on it. That's how I roll. I've also been known to put mushrooms on it. Anchovies and pineapple go well together. The contrast of the saltiness with the sweetness is good. I might even put some sauteed onions on it. You just never know. One thing I don't do is pile on a whole bunch of different toppings. I use two at the most. If I make it for other people, I'll put sausage or pepperoni on it, but I'm not crazy about that. Get some fresh mozzerella if you can find it. It is possible to make it, though, and there are YouTube videos about it. Just tear it up with your hand and put it on the pizza.
<p>
Stick that back on the pizza stone, and cook it until all the cheese is melted and the crust is a nice golden brown. I can't give you a time because I don't know how the laws of physics operate in your particular oven. But just watch it. You know what a pizza is supposed to look like when it's done.
<p>
Once it's done, take it out, put it on a rack, let it cool a couple of minutes. At this point, I'll sometimes put some fresh basil on it. It goes great with a plain cheese pizza. Finally, transfer it to a cutting board, cut it up, and eat it.
<p>
You're welcome.

One argument against thought experiments involving philosophical zombies is that philosophical zombies are incoherent, and I half way agree with that.
<p>
Consider two people, both named Bob. To distinguish them we'll call them Bob Normal (Bob<sub>N</sub>) and Bob Zombie (Bob<sub>Z</sub>). Physically, Bob<sub>N</sub> and Bob<sub>Z</sub> are identical. Atom per atom, they are exactly alike. They look the same, behave the same, say the same things, etc. To keep them from occupying the same space at the same time, let's put them in separate worlds that are also identical.
<p>
Identical, that is, with one exception. Bob<sub>N</sub> is conscious and Bob<sub>Z</sub> is not.
<p>
Some folks think this is an incoherent scenario, and I agree. It's incoherent whether you assume physicalism or dualism. Let me explain why each scenario is incoherent.
<p>
<i>Let's assume physicalism</i>
<p>
If physicalism is true, and Bob<sub>N</sub> is conscious, that would mean the physical structure of Bob<sub>N</sub>'s brain is what's giving rise to his conscious experiences. If Bob<sub>Z</sub> has the exact same physical structure as Bob<sub>N</sub>, then it would be impossible for Bob<sub>Z</sub> not to be conscious. That makes the scenario incoherent.
<p>
<i>Let's assume dualism is true</i>
<p>
If dualism is true, then the explanation for why Bob<sub>N</sub> is conscious and Bob<sub>Z</sub> isn't is because Bob<sub>N</sub> has a soul and Bob<sub>Z</sub> doesn't. Much of Bob<sub>N</sub>'s behavior is the result of causal interactions between his brain and his soul. Since Bob<sub>Z</sub> doesn't have a soul, the same interactions are not going on in his head, and it is impossible that they behave the same way. That makes the scenario incoherent.
<p>
So either way you look at it, a scenario in which Bob<sub>N</sub> and Bob<sub>Z</sub> are physically identical and behave in exactly the same way is an incoherent scenario.
<p>
So how can the idea of a philosophical zombie contribute anything to the subject of dualism vs. physicalism? Some arguments rely on the possibility or conceivability of philosophical zombies to make their point, but I don't think that's necessary. A hypothetical scenario doesn't have to be possible to serve as an illustration. For example, Aristotle imagined what a world would be like without the law of non-contradiction. There would be no significant or meaningful speech or action in such a world. His point doesn't depend on such a world being possible.
<p>
In the same way, I think philosophical zombies can be invoked to illustrate how physicalism leads to epiphenominalism which, in turn, undermines physicalism, even if philosophical zombies are impossible. Here's a basic outline of the argument.
<p>
If physicalism is true, then all of our behavior (including our vocalizations) can be accounted for solely by reference to the third person properties of the brain and its parts, plus the laws of nature. You can explain exhaustively why somebody behaves in a particular way without ever referring to anything like a motive, belief, idea, desire, thought, plan, perception, etc. With that being the case, our behavior would be exactly the same even if these first person experiences didn't exist. Nevermind whether it's <i>possible</i> for them not to exist given our actual brain states. The point is that <i>if</i> our behavior would be the same in their absense, that means they don't contribute to our behavior. But that is absurd, so physicalism is false.
<p>
One objection somebody might raise to the above argument is that explaining behavior in terms of physics vs. psychology are just two ways of explaining the same thing. They are two layers of abstraction. It's similar to the difference between explaining the output of the computer in terms of functions like addition and subtractions as opposed to explaining it in terms of current, voltage, and the properties of electrons and various computer components.
<p>
But the same thing applies here. It is not because two and two actually make four that your calculator spits out that result. It would spit out that result even if the circuits didn't happen to represents the number two or the process of addition. You can program a computer to spit things out that are meaningful to us, but their meaning is irrelevant to the process by which the computer spits it out. It takes a conscious engineer and programmer to make a computer that spits out what, to us, is meaningful information.
<p>
In the same way, even if conscious experience is somehow the same thing as physical brain stuff obeying the laws of physics, it wouldn't matter one bit what those conscious expereiences are <i>about</i>. If some brain state associated with a sensation of burning resulted in jerking your hand away from a hot skillet, it would result in that same behavior even if it happened that the brain state was associated with a different conscious experience or no conscious experience at all. Under phyiscalism, it isn't by virtue of what our conscious experiences are <i>about</i> that results in our behavior. Rather, it's just the underlying physical substrate that produces our behavior whether the associated conscious experiences were about something different or absent altogether.
<p>
And that's just cray cray. I think the philosophical zombie thought experiment is useful to illustrate this even if they are not actually possible for the reasons I gave above.
<p>
Besides all that, it seems to me that artificial intelligence shows how something <i>like</i> a philosophical zombie could exist. Something resembling a human could exist that behaves just like a human, including having conversations and showing physiological behavior we usually associate with expressions of emotion without actually being conscious. If such a machine ever became conscious, we'd probably have no way to know it.

There are a handful of things we know by intuition that are not necessary truths. Most other things we know depend on us knowing these handful of things. They include, but are not limited to, morality, the external world, the past, other minds, and the uniformity of nature. But within these intuitions, there are actually two things to know about each of them.
<p>
<i>Morality</i>
<p>
1. We know that there is a real objective difference between right and wrong.<br>
2. We know some particular behaviors are right and others are wrong.
<p>
<i>The external world</i>
<p>
1. We know that there is an external world.<br>
2. We know that particular things we perceive are part of the external world.
<p>
<i>The past</i>
<p>
1. We know the past actually happened.<br>
2. We know some particular memories we have correspond to what happened in the past.
<p>
<i>Other minds</i>
<p>
1. We know there are other minds.<br>
2. We know there's a mind behind the behavior of particular people and sometimes animals.
<p>
<i>The uniformity of nature</i>
<p>
1. We know the future will resemble the past.<br>
2. We know that particular things will happen in the future because we've observed them repeatedly in the past.
<p>
In each of these categories, we are less sure about the particulars of the second items of knowledge than we are the first. In fact, we make mistakes when it comes to the second items of knowledge all the time. However, in each case, the fact that we can often be wrong with regard to the second is never a sufficient reason to doubt the first.
<p>
The fact that people disagree on morality, and the fact that we sometiems change our moral point of view shows that we often have incorrect beliefs about right and wrong, but that is no reason to doubt that there <i>is</i> such a thing as right and wrong.
<p>
Most of the time when we dream, we think everything we are perceiving is real, but none of it is. When we are awake, we see illusions and mirages. Some people experience hallucinations, phantom limb syndrom, or they hear things. Even in the case of people with psychosis who experience more than the usual amount of faulty perceptions, that is never a reason to doubt the existence of the external world entirely.
<p>
I've lost count of how many times I've heard people say, "Memory is notoriously unreliable." While I think that view is <a href="https://philochristos.blogspot.com/2019/04/knowledge-by-memory.html">overblown</a>, it is true that our memories often fail us. It's not just that we are forgetful. It's that we remember things differently than they actually happened. If you've ever been in a relationship for a significant period of time, you've probably had an argument over how something happened because you each remember it differently. I'm sometimes surprised when I read what I wrote in my journal years ago to discover things happened a little differently than I remember. Our memories are very fallible. However, that is no reason to embrace Last Thursdaism or doubt that there even <i>was</i> a past.
<p>
People are notorious for anthropomorphizing--attributing human traits (e.g thought and emotion) onto inanimate things. We also attribute the wrong mental states to things that have minds. We misread each other and misunderstand each other, but it's even worse when we project human traits onto other animals. Some people err in the opposite extreme and think animals have no thought or emotion. Some even go so far as to think animals are not conscious at all. With some bugs and worms, it's hard to even know if they have any conscious experience. However, the fact that we make all of these mistakes when trying to understand the minds (or lack of minds) of others is no reason in the world to doubt that there are other minds.
<p>
Hasty generalization is a fallacy we've all been guilty of at one time or another. It's probably the main reason superstition exists. We make generalizations by extrapolating from too few instances. We've all done it. Also, we often <i>under</i>-generalize. We refuse to learn from past experience. We can be stubborn and think next time will be different. However, the fact that we often make mistakes when reasoning inductively is no reason at all for us to doubt the validity of inductive reasoning.
<p>
Our confidence in the first item of knowledge under each category is why we exert so much effort toward being right about the second.
<p>
We debate moral issues and engage in moral reasoning because we think there are correct and incorrect answers to moral questions.
<p>
We rub our eyes when we suspect we're seeing things or ask others, "Did you hear that?" when we think we might've heard a suspicious noise. We do this to weed the bad perceptions from the good perceptions because we think there's a real world out there, and we want to make sure we're seeing it as it really is.
<p>
We write things down, look for corroberating testimony or evidence, strain our brains to remember how things really happened, and we retrace our steps in an effort to clarify our memories. We argue with people who remember things differently because we know that <i>something</i> happened. It's just a matter of finding out what.
<p>
When we initially notice patterns, we test them to see if they continue to repeat, and if so, under what circumstances. We formulate laws that describe in a mathematical way how we should expect the world to operate from here on out. We test these laws by making observations, and we extrapolate from the test to the rest of the world. If water boils at the same temperature under the same pressure every time we run the test, then we assume that's just the way water is, and it should apply just as well to samples of water we haven't tried to boil. We do these experiements because we know that experience can tell us what we should expect the world to be like going forward.
<p>
Most of the things you know, or think you know, can be traced back to these handful of <i>a priori</i> truths or truths like them. Others I didn't go into include causation, the law of parsimony, the notion that ought implies can, the reality of time, an enduring self, intentional action, object permanence, and the reliability of our cognitive faculties in general. For most people, the knowledge of these things is so automatic that they never even think about them. The knowledge runs in the background. But if you thoughfully ask, "Why do you think that?" for almost any random thing you know about the world, and you keep asking, you will eventually trace the belief back to one or more of these items of <i>a priori</i> knowledge.
<p>
Usually, that's where the line of inquiry stops. These items of knowledge are part of the foundation of all knowledge. They aren't inferred from something prior. The information is just built into us. We're hard wired to believe these things. Since these items of knowledge come pre-loaded into the brain of every reasonably developed human mind, and they are not inferred from evidence or argument, we know them by intuition. Intuition is immediate knowledge upon reflection. We don't turn our gaze outward to see if these things are true; rather, we turn our gaze inward and simply see what is written on the mind.
<p>
There are some people who attempt to find something even more foundational than these items of knowledge. They'll try to come up with reasons for why we should believe them other than intuition. However, the reasons always turn out to be less obvious than the truths themselves. That casts doubt on whether those reasons are what actually justify the beliefs or lead to the beliefs. Even if any of these attempts at arguing <i>for</i> one of these truths is a sound argument, the argument is probably not why we actually believe those truths.
<p>
It is possible for each of these things to be false. After all, none of them are necessary truths. But just because something is possible doesn't mean it's reasonable to believe. In the case of these <i>a priori</i> truths, it is <i>unreasonable</i> to doubt them, especially the first item of knowledge under each category. But that doesn't stop some people.

Timothy and Lydia McGrew and Eric Vestrup published a paper called "Probabilities and the Fine-Tuning Argument." They came up with an objection to the argument from fine-tuning that's based on the fact that you can't specify the probability of a finite range of values over an infinte range of possibilities. The reason is because the probability wouldn't be normalizable.
<p>
According to the principle of indifference, if you don't know what the probability distribution is over some range of values, then you assume an equal probability distribution. That is, you assign an equal probability to each possibility. For example, if you had a six sided dice, and you didn't know if it had been ground in such a way as to make it more likely to land on 2 than on 3, then you assume it has an equal chance of landing on any side. Each side would have a 1 in 6 chance of landing face up. Since each side has a 1 in 6 chance of landing face up, and there are six sides in all, then if you add the probabilities for each possible outcome, the total is 1.
<p>
<blockquote>1/6 * 6 = 1</blockquote>
<p>
If the probability distribution is <i>not</i> even, then whatever the probability of each side is, they should still add up to 1. The reason is because all the possibilities added together sum up to a guarantee. If you roll the dice, <i>some</i> side is guaranteed to face up. Otherwise, you haven't accounted for all the possibilities.
<p>
That's what it means for a probability distribution to be normalized. It means the individual probabilities of all the possibilities add up to 1 or 100%.
<p>
It is possible to normalize a probability distribution over an infinite range of possibilities, though. Consider a convergent series that sums to 1, such as this:
<p>
<blockquote>1/2 + 1/4 + 1/8 + 1/16 + . . . + 1/infinity = 1</blockquote>
<p>
So if you had a probability distrubtion over an infinite range of possibilities in which the possibilities were put in one to one correspondence with that convergent series, you could normalize that probability distribution.
<p>
If you were using the principle of indifference, though, then you couldn't noramlize the probability distribution over an infinite range of possibilities. First of all, the probability of each member would be 1/infinity, which is zero. Second of all, even if it weren't zero, but was some small finite number, the probabilities of each possibility wouldn't sum to 1. It would sum to infinity.
<p>
Another related problem is that if the range of possible values is infinite, then the probability of any finite range within the total range would be infintesimal. That would render fine-tuning meaningless because no matter how big the life permitting range of some value is, as long as it's finite, the universe would still be fine-tuned. 1/n approaches zero as n approaches infinity, but the same thing is true of 10<sup>500</sup>/n. It doesn't matter how big the life permitting range is. If the range of possible value is zero to infinity, the probability of getting something in any finite-sized life permitting range is still infintesimal. To paraphrase Syndrome, "If everything is fine-tuned, then nothing is."
<p>
Luke Barnes, an astrophysicist from Australia, published a philosophical paper responding to the normalizability objection. The paper is called "<a href="https://arxiv.org/pdf/1707.03965.pdf">Fine-Tuning in the Context of Bayesian Theory Testing</a>." Most of this paper is over my head, but after furrowing my eyebrows and twisting my hair around my finger, I think I have gotten a handle on one particular paragraph on the bottom of page 7 of his paper that I want to talk about today.
<p>
I'm going to use the rest mass of an electron to explain, as best I can, how we can limit the possible range of values in order to normalize the probability distribution of those values. Basically, we can limit the range by what makes sense within the theories that describe the electron.
<p>
Bear with me. There's going to be a little math. Nothing too difficult. Also, just as a disclaimer, Luke doesn't go into all this math in that paragraph. Once I thought I understood what he was saying, I went and crunched the numbers to see for myself. Physics makes more sense to me if I can see the math. This is my attempt to break it down and explain it to you in a way that's more detailed and easier to understand (I think). If there are mistakes in these details, they are mine, not Luke's.
<p>
There are two theories that come into play in this explanation. There's quantum mechanics, and there's general relativity. According to general relativity, if you condense a given amount of mass to within a certain radius, it will become a black hole. The radius at which a given mass becomes a black hole is called the Schwarzschild radius. Here is the equation for the Schwarzschild radius:
<p>
<blockquote>R = 2mG/c<sup>2</sup>
<p>
m = mass<br>
G = the gravitational constant = 6.6743 x 10<sup>-3</sup> N*m<sup>2</sup>/kg<sup>2</sup><br>
c = the speed of light = 299,792,458 m/s</blockquote>
<p>
The rest mass of an electron is 9.109×10<sup>-31</sup> kg, which is 0.511 MeV. We can plug that into the equation to calculate the Schwartzschild radius for an electron.
<p>
<blockquote>R = (2 * 9.109x10<sup>-31</sup> kg * 6.6743x10<sup>-3</sup>N*m<sup>2</sup>/kg<sup>2</sup>)/(299,792,458 m/s)<sup>2</sup> = 1.35x10<sup>-49</sup> meters</blockquote>
<p>
That's pretty small. Nobody really knows how small an electron actually is, though. There were some experiments where they bounced some electrons off of each other. They tried to figure out how big they were by looking at the scattering pattern, but it looked like they were point particles with no size at all. You'd think that if an electron were that small, it would be a black hole. If it has no size, but some finite mass, then it's density would be infinite. Zero radius is well within the Scharzschild radius. So what the what, you ask?
<p>
Well, that's where quantum theory comes into play. In quantum theory, the size of an electron is defined by it's Compton wavelength.
<p>
<blockquote>
λ = h/mc
<p>
h = Planck's constant = 6.626x10<sup>-34</sup> joule-seconds<br>
m = mass<br>
c = the speed of light = 299,792,458 m/s</blockquote>
<p>
Instead of running the calculation this time, let's just get the Compton wavelength off the internet. For an electron that's 2.426×10<sup>−12</sup> m. Notice the Compton wavelength of an electron is many orders of magnitude bigger than its Schwartzschild radius. That's why the electron is not a black hole.
<p>
But suppose the electron was more massive. Well, there's a limit to how massive an electron could be before it becomes a black hole. To figure out what that limit is, let's set the Schwartzschild radius equal to 1/2 the Compton wavelength and solve for mass.
<p>
<blockquote>2mG/c<sup>2</sup> = (1/2) * (h/mc)<br><br>
So, m = Sqrt (hc/4G)
<br><br>
m = Sqrt ([6.626x10<sup>-34</sup> J*s x 299,792,458 m/s]/[4 * 6.6743 x 10<sup>-3</sup> Nm<sup>2</sup>/kg<sup>2</sup>]) = 2.73x10<sup>-12</sup> kg
</blockquote>
<p>
In case you're worried about the units, 1 Joule is 1 kg*m<sup>2</sup>/s<sup>2</sup> and 1 Newton is 1 kg*m/s<sup>2</sup>. The units works out. Don't worry. I did this on paper first. It's that total that might be wrong in case I made a typo in my calculator.
<p>
Notice that all of this just takes quantum theory and general relativity to their logical conclusions and predicts the highest mass an electron could have before becoming its own black hole. In reality, it's hard to say what would happen if an electron were that massive. Quantum mechanics and general relativity conflict on those kinds of scales, and we need a theory of quantum gravity to know what <i>really</i> happens.
<p>
But what this shows, according to Luke Barnes, is that there is a finite range of values an electron can take before our theories start to break down. Beyond that range, we can't trust quantum mechanics and general relativity. If we want our theories to make sense, then we <i>have</i> to place a limit on the range of possible values various constants can take. In the case of the electron, we can limit the possible range from zero to 2.73x10<sup>-12</sup> kg. Zero is a natural place to put the lower limit because negative mass doesn't make much sense. But if you don't like that, then you could put the lower limit at -2.73x10<sup>-12</sup> kg. Either way, we'd have a finite range of possible values, and that would allow us to normalize our probability distribution.
<p>
According to Luke Barnes, what I just showed with the electron can also be done with other constants. For constants that have units, like the mass of an electron, Luke says we can use the Planck scale to define a finite range of possible values to the constants. The Planck mass is actually bigger than the mass I calculated, so either Luke is being generous, or I've made some mistake. For constants that don't have units, we can limit those ranges in other ways that I didn't go into in this blog post. He went into that in his paper, too.
<p>
There's a lot more to Luke's paper, and most of it I don't understand. What I just explained was my interpreation of the last paragraph on page 7 of his paper. If you read his paper, and you get to that paragraph, please leave a comment and tell me if you think I've misunderstood something or if I made some mistake.

Ordinary media (whether news papers, magazines, or news networks) are very unreliable when it comes to reporting new findings in science. They often distort the facts or give misleading information. A good example of that is the false or misleading information they put out about advances in fusion technology. Unfortunately, there are even some popular scientists who distort the facts when they're hungry for media attention. Sometimes I think the reason is just a desire to be sensational because sensationalism sells. Sometimes it's because the people reporting science news just don't understand the science.
<p>
Thankfully, we are not at the mercy of these sources anymore. There are actually competent people on YouTube who do a much better job of reporting space and science news than what you can get on TV, magazines, or news papers. I'm going to direct you to four of my favourites.
<p>
<b>Fraser Cain</b> (not to be confused with Frasier Crane)<br>
This guy is not a scientist, but he is an unusually competent and knowledgable science journalist, so I recommend him.<br>
<a href="https://www.youtube.com/@frasercain/videos">https://www.youtube.com/@frasercain/videos</a>
<p>
<b>Anton Petrov</b><br>
This guy is also not a scientist, but I think he used to be a science teacher.<br>
<a href="https://www.youtube.com/@whatdamath/videos">https://www.youtube.com/@whatdamath/videos</a>
<p>
<b>Sabine Hossenfelder</b><br>
Sabine is an actual physicist. She used to mostly talk about topics in physics, but lately she's become more of a science news channel. Besides being interesting and informative, she's also entertaining.<br>
<a href="https://www.youtube.com/@SabineHossenfelder/videos">https://www.youtube.com/@SabineHossenfelder/videos</a>
<p>
<b>Dr. Becky</b><br>
Becky is an astrophysicist. Most of her stuff is about stars, galaxies, and astronomy. Her specialty is black holes. Becky is fun to watch becasue of how enthusiastic she is about the topics she discusses.<br>
<a href="https://www.youtube.com/@DrBecky/videos">https://www.youtube.com/@DrBecky/videos</a>
<p>
If you're interested in physics, cosmology, astrophysics, or astronomy, you should subscribe to all four of these people. But they do sometimes talk about other things, like other fields of science as well as technology. I highly recommend all four of them.

There are things people readily believe today there were thought of not merely as incorrect in the past, but as so utterly absurd that they were used in <i>reductio ad absurdum</i> arguments. If you held a point of view that, when taken to its logical conclusion, led in an absurdity, then that cast doubt on the truth of that point of view. That's how <i>ad absurdum</i> arguments <i>used</i> to work.
<p>
I can't remember the context, but I remember using an <i>ad absurdum</i> argument in which the absurity was that I claimed to be a black woman even though I'm obviously a white man. The argument probably had to do with whether claiming to be something meant that you <i>were</i> that thing, like claiming to be a Christian even though you denied the existence of God or the resurrection of Jesus. That <i>reductio</i> probably wouldn't work today because the absurdity is no longer considered absurd.
<p>
About 24 years ago or so when I first started reading pro-life literature, I came across a <i>reductio ad absurdum</i> argument meant to show that the fetus was a distinct organism rather than being a part of its mother. The argument was that if the fetus were a part of the mother (like an organ or an appendage), then you could have a woman with two heads, and in the case of a male fetus, a woman with a penis. If you tried to use that argument today, people would say, "But women <i>can</i> have penises."
<p>
We live in crazy times, and it's getting crazier. I wonder if some day <i>reductio ad absurdum</i> argument will no longer be considered a valid way of reasoning. Maybe they will be moved to the "logical fallacies" part of the logic text books since nothing is absurd.
</p>

I become increasingly frustrated listening to panel discussions, interviews, cross examinations, debates, and even just regular conversation between average every day people. It seems like nobody is really interested in what anybody else has to say. Everybody wants to interrupt and talk over the other people. One person will ask a question of another person, but they won't let them answer. Often they will interrupt just to say, "You're not answering my question." Everybody wants to steer the conversation in a certain direction, but nobody else will let them, so nothing really ever gets fleshed out in a conversation. It's all surface level jumping from one topic to another in kind of a multi-directional tug-of-war.
<p>
I got into a rabbit hole of binge watching police interrogations on YouTube a few months ago. I noticed a huge difference between the way these interrogations take place and the way TV interviews, debate cross examination, and Congressional testimony goes down. The difference is that the police give the suspects as much room to talk as they can. They do everything they can to keep them talking, hoping all the while that they don't invoke their right to remain silent. The reason is because they know that the more the person talks, the more likely they are to give up a piece of information the police can use. So they don't interrupt the suspect even when they know the suspect is lying or being evasive. If the suspect has a story to tell, the cops will let them go on and on, and the cops listen to everything they say.
<p>
Why the difference? Well, I think it's because in most cases, we aren't actually interested in what other people have to say. We're just interested in what <i>we</i> have to say. We want to be heard, but we don't want others to be heard, especially when they disagree with us. We're not actually interested in learning anything from anybody. We just want others to learn from us. Often we don't think others have anything to teach us, but we think we have something to teach them. There is a general lack of respect we have toward people who see things differently than we do.
<p>
The police are trying to find out the truth. They know they're going to be lied to if the person is guilty, but even lies can be useful information. If somebody is in a debate, interview, or cross examination, the object isn't to find out the truth, but to win the conversation. In the case of Congressional testimony, it's often just posturing.
<p>
Of course the police can be very manipulative. I'm not claiming they're more honest than the rest of us. I'm just attributing their tactics to the difference in goals. I think that we should be more like the police in these interrogations, not in the sense of being manipulative, but in the sense of letting others speak and listening to them with the goal of eventually revealing the truth. The police, more than politicians, the media, apologists, or just your friends, family, and neighbors, are very interested in what the other person has to say. They make it their goal to draw them out as much as possible, to get them to say as much as possible, and to think carefully about what they are saying.
<p>
That is what we should do. Sometimes, we'll ask a question that's based on our assumptions or frame of reference, but if the other person doesn't share those assumptions or frame of references, and they try to respond, it's going to sound at first like they're not asnwering our question, and we're going to be tempted to interrupt them and say, "Just answer the question!" But we shouldn't do that. Instead, we should hear them out. Let them talk. Maybe it'll turn out that we had a misunderstanding. Maybe they'll make some necessary clarification we hadn't anticipated. Maybe they'll say something that doesn't directly answer the question we're asking but still contributes meaningfully to the conversation. Maybe it will reveal more clearly where the misunderstanding lies or why it seems like you're talking past each other. At the very least, it will give us more information about what's going on in the other person's head.
<p>
And besides that, it's the polite thing to do. As I said before, we all want to be heard. That's why we interrupt and talk over people. With that being the case, you should strive to be the one that's listening. It's an act of kindness and a show of respect to hear somebody out, show curiosity, listen to them, and think about what they are saying. One of the best compliments I've ever recieved was when somebody said, "I thought about what you said."
<p>
If you're an apologist (whether for theism, atheism, capitalism, socialism, or whatever), and you really <i>want</i> to advance your point of view, it still behooves you to hear the other person out and let them speak as much as possible. Just as in the case of the police, that will give you information to work with. You are in a better position to reason with somebody if you know how their mind works, what they already believe, and how they think. So you should make an effort to draw people out and not get flustered when they aren't directly answering your questions the way you'd like. You should still let them finish because they might say something else you didn't know but can use. Or it might be that they just have a round-about-way of communicating, in which case you just need to be patient.
<p>
In my own case, I can tell you that I often interrupt people because they are throwing too much information at me at once, and I can't process all of it. I need it in smaller doses so I can think about it and ask questions. If somebody monologues for ten minutes, and I have all kinds of things to say while they're talking, I'm not going to remember any of it when their ten minutes is up, and they want me to respond. Sometimes straining my brain to keep track of something somebody says so I can respond to it when they're done makes it difficult for me to pay attention to the rest of what they have to say. That's not as big of a problem in a classroom setting because I <i>expect</i> the lecturer to monologue, and I take notes so I can ask questions about something they may have said fifteen minutes earlier. Of course conventional wisdom is that you should listen to understand rather than listening to respond, but in reality, we do both. One does not simply give up the urge to respond, and one <i>shouldn't</i> give up the urge to ask follow-up questions.
<p>
I suspect I'm not alone and that some of you might interrupt people for a similar reason. While this post is mainly geared toward encouraging you to be a good listener, and not to be the obnoxious interrupter, I don't want to end this post without also saying that you should strive to be patient with those who interrupt you and who seem like they aren't listening to you. Maybe they aren't, but not all interrupting is a sign of disrespect or disinterest. The case of interrupting to keep your train of thought is just one example. Another is interrupting on accident because you thought the other person was done when they were just pausing for dramatic effect.
<p>
But even when people interrupt for bad reasons, we should be patient with those people, too. Dealing with people in general requires patience because none of us are perfect. We're all sinners, we can all be selfish, and we're all a little bit self-absorbed. If you can't be patient with people, you're going to grow to dislike people more and more as you get old, and then you're going to be all alone.

Sam Harperhttp://www.blogger.com/profile/15884738370893218595noreply@blogger.com0tag:blogger.com,1999:blog-10407988.post-15810161009035781712023-06-14T13:07:00.004-04:002023-06-14T13:44:34.527-04:00David Grusch is probably lying, and other thoughts on aliens and UFO's<p>
As much as I would like to find out there are aliens among us, I don't think there are. But I'm hopeful enough that I watched <a href="https://www.newsnationnow.com/space/ufo/we-are-not-alone-the-ufo-whistleblower-speaks/">the interview with David Grusch</a>. Before watching the interview, I was suspicious of the story because of my general skepticism toward alien visitation. I didn't know whether he was deceiving or was himself deceived, though. In clips I saw before the full interview, I got the impression that he hadn't seen any evidence of aliens himself. He was getting all his information from other people. But now, having seen the full interview, I think it's more likely that he's lying than that he believes what he's saying and is just duped.
<p>
First, there's just a vibe I get from his manerisms and the way he talks that gives me a subjective feeling that he's lying. I used to put no confidence in this sort of thing until experience taught me that when my gut tells me something about somebody, it's usually right. Of course it's a stronger impression with some people than with others, and in his case, my gut wasn't <i>screaming</i> that he's lying. It was just elbowing me that he's lying.
<p>
Second, he engaged in a little psuedoscientific non-sense during the interview. At the 7:50 mark, he appeals to his physics background to raise the possibility that they could be interdimensional beings. He says, "I couch it as somebody who studied physics where maybe they're coming from a different physical dimension as described in quantum mechanics. We know there's extra dimensions due to high energy particle collisions, etc., and there's a theoretical framework to explain that, yeah." The theoretical framework he's probably referring to is string theory (or M theory) because that's the only viable theory in physics that involves extra dimensions. In the most current version of string theory, there are ten spatial dimensions and one temporal dimension. We only see three spatial dimensions because the others are all compactified. Individual strings can vibrate within the extra dimensions, which is what gives particles their properties, but you couldn't have a whole civilizations living in them with living beings that could travel back and forth between those dimensions and ours. That makes no sense within string theory. It treats these extra dimensions as if they are different three dimensional realms like ours that a being could living in and be separate from our three dimensions. That is the stuff of science fiction, but it has no relationship to real physics, not even string theory. But worse than that, his claim that we <i>know</i> there's extra dimensions due to high energy particle collisions is flat out false. There's no evidence at all that string theory is true other than its internal consistency and its prediction of gravity, and there have been no studies at CERN or any other collider showing anything at all about extra dimensions. This is all psuedoscientific nonsense, and I think the fact that he appeals to his own study of physics to make these claims shows that he's lying.
<p>
Third, he used words (or tried to use words) that are obviously not part of his usual vocabulary. This shows that he's pretentious. He's trying to come across as more intelligent, professional, and authoritative than he really is. I'm always a little suspicious when people behave that way. I'll give some examples. At one point, he talks about aliens being interested in our nuclear weapons, and he says they wanted to see how far we had advanced in our "fizzle" technology (18:50). He probably meant fission technology. <a href="https://en.wikipedia.org/wiki/Fizzle_(nuclear_explosion)">Fizzle</a> is what they call it when a nuclear bomb underperforms, so "fizzle technology" is nonsense. At another point he said, ". . .true nonprosaic UAP situation could be <i>constrived</i> as, you know, a provocation. . ." (32:00) <i>Constrived</i> isn't a word. He probably meant to say "construed," but he got it mixed up with "contrived." He came across as pretentious in his word choices throughout the interview, and the whole thing just raised my suspicions about his honesty.
<p>
Pretentiousness is something I've noticed with some Christian apologists, too. I noticed it a lot with Ravi Zacharias. It isn't just speaking intelligently or with a good vocabulary. William Lane Craig speaks intelligently, but he rarely strikes me as pretentious. It's hard to put my finger on it, but I recognize it when I hear it. It comes in unnecessary word flourishes or obscure word choices when more common words work just as well or better. People sometimes say things like "constrived" when they're trying too hard.
<p>
Pretentiousness has its place, though. If you're writing poetry or some literary masterpiece or you're trying to get published or noticed, it makes sense to be a little pretentious. In those cases, you're trying to dazzle or impress. But if you're just trying to communicate information, the object should be clarity over other considerations, and too many times I've seen people sacrifice clarity in an effort to appear intelligent, sophisticated, or authoritative. It's especially noticeable when somebody tries too hard and doesn't fully understand the words they're using.
<p>
To be fair, though, there's at least one thing that counts in favour of Grusch's honesty. Allegedly, he testified under oath about these things. So, he put himself at risk of some kind of prosecution if he's caught lying. That does count in his favour. It's not enough to convince me, though, because I don't know what he actually said under oath. I just saw the interview. He wasn't under oath during the interview. For that matter, I'm not certain he testified under oath. I only heard that he did. I suspect he probably did because he does seem eager to have Congress or somebody look into these things. At the very least, you'd think he'd be <i>willing</i> to testify under oath.
<p>
I'm not saying that I know, am uttelry convinced, or that I'm absolutely sure that Grusch is lying. I think he's probably lying, but I could be wrong. That's all I'm saying.
<p>
Let me say something about my skepticism that aliens are visiting us. First, I don't claim that it's impossible. I just think it's highly unlikely for a few reasons.
<p>
I used to think it was nearly impossible that aliens have visited us becasue of an argument I used to have. The only reason a civilization would go to the enormous trouble of singling out another solar system among the billions that exist in our galaxy is if there were something that set it apart, and about the only thing that would set one apart is if it had life (especially intelligent or advanced life) on it. The only way aliens could know there was intelligent life on our planet was through our radio waves. The farthest our radio transmissions could possibly have traveled by now is 100 light years. The fastest anybody could possibly travel is near light speed. So the farthest any aliens who visit us could be is 50 light years away. That gives 50 years for our radio signals to alert them that we were here, and another 50 years to travel here. But realistically, our early radio waves are too weak to be detected 50 light years away, and realistically there's probably no aliens near us that could travel at nearly the speed of light. So realistically, any aliens visiting us are probably no more than 20 light years away, which is still generous. A civilization capable of traveling that distance would surely have more radio signals than we have, and since we've searched the skies for decades and haven't detected any alien radio signals, they're probably not within 20 light years of us.
<p>
This argument isn't nearly as strong as I originally thought because there are other ways for aliens to detect us than radio waves. They could detect life on our planet through spectroscopy. We are developing telescopes that can take the light that shines from a distance star, through the atmosphere of one of its planet, to a prism or something, breaking that light into its separate wavelengths. By looking at the spectrum, we can figure out what the atmosphere of that planet is made of since different chemicals absorb specific wavelengths of light. This could, potentially, allow us to detect life on other planets since organic life can release chemicals into the atmosphere that aren't produced any other way than by organic processes. With a more powerful telescope, we could do these observations for more and more distant stars. So it's possible life was discovered on our planet as much as a billion years ago by a civilization as much as a thousand light years away. Any aliens living closer than that might have time to reach us. It could be that aliens have been visiting our planet for millions of years.
<p>
But I'm still very skeptical. I think my argument was right that aliens wouldn't attempt to come here unless they had some really compelling reason to do so and that the knowledge of life here (or at least the high probability of life here) is about the only thing that could single us out. Well, there's that and proximity. If there were life in the Proxima Centauri system, they might send probes here just because we're nearby.
<p>
One reason I'm skeptical is because I think life is probably rare in the galaxy, and intelligent advanced life comparable to our own is vanishingly rare. The reason I suspect life in general is rare is because of the difficulty scientists have had in figuring out how we got from simple organic compounds, to self-replicating RNA, to fully formed cells. I suspect the difficulty is because it was a fluke, unlikely, extremely rare series of events. Besides that, it seems to have only happened once on our planet. Or if it did happen more than once, none of the other lines of transmission have survived.
<p>
Some people say the fact that it happened so early on our planet shows that it's not an unlikely event. I used to think that was a good argument, but I don't anymore. The fact that life started very early on our planet might be an observer selection effect. It took four billion years to go from single celled organisms to intelligent human beings. If it's normal for intelligent life to take that long to develop, then life would <i>have</i> to start early on any planet that has intelligent life. If life started too late, then there wouldn't be enough time for intelligent beings to evolve. At the very most, we've only got about a billion more years before all life ceases to exist on this planet because our sun is getting hotter and brighter all the time. So if life started three billion years ago instead of four billion years ago, intelligent life would never have evolved on our planet. So any planet with intelligent life comparable to our own might <i>have</i> to be a planet where life happened to start early. The fact that life started early on our planet, then, might be due to an observer selection effect rather than because it's easy or likely for life to arise from simple compounds.
<p>
So I suspect that life in general is rare in the galaxy. If there is life all over the galaxy, the vast majority of it is probably just single celled life. It took three billion years on our planet to go from single celled life to multicellular life. The jump to multicellular life must have been an extremely unlikely event. The unlikelihood of it is bolstered by an argument I've heard from <a href="https://pspruett.wordpress.com/2018/07/15/the-statistical-case-against-evolution/#comment-1814">Paul Scott Pruett</a> and others about how rare functional sequences of amino acids are compared to non-functional sequences of a given length, like the average size of a protein molecule. So I suspect that the jump from single celled organisms to multicellular life is also rare on other planets.
<p>
There are a long series of unlikely events that happened on our planet that resulted in our being here. I don't want to go into those details because this post would be too long if I did. I just want to say that given hundreds of billions of stars in our galaxy, it might not be impossible that it's happened more than once. Even so, I still think exo-planets containing intelligent life would be few and far between. So it is highly unlikely that there's another advanced civilization near enough to make traveling here feasible.
<p>
But let's suppose there is or has been an intelligent species within 10 light years of us. There are still a lot of filters that might prevent them from ever coming here. One is the question of how long intelligent civilizations usually last. It seems like the longer ours lasts, the more likely it starts looking like we're going to destroy ourselves through nuclear war or destroying the planet through exploitation. There's also natural disasters that cause mass extinctions. We've had several mass extinctions on our planet. So it's hard to say how long intelligent species last on average and whether any would last long enough to develop the technology needed for interstellar travel. Even if a species isn't wiped out, they could be seriously set back. Our civilization becomes more and more fragile the more we rely on electricity and satelites. If we had a coronal mass ejection like the Carrington event today, it would cause far more damage to society than it caused in the 1850's, and it seems like it's just a matter of time before that happens.
<p>
Distance is a huge obstacle to any species wanting to travel to other solar systems. Unless they can travel near the speed of light, there's not much hope of getting anywhere within one lifetime. You can imagine intergenerational ships to overcome this problem, but that has problems of its own since energy, food, and resources have to come from somewhere. Plus, it has to be worth it to the passengers, and they better hope their ship doesn't break down on the way. The technology needed for something like that isn't just a few years away. It's probably thousands of years away. It's a major undertaking.
<p>
There are obstacles in space, too. Two of the biggest are radiation and rocks. The James Webb Space Telescope was hit by a grain of sand or something shortly after it deployed. Space debris is everywhere, and it's traveling super fast. <i>You</i> would have to travel super fast to get to another solar system in a reasonable amount of time. A small pebble could destroy your ship at that speed. Any ship that hopes to overcome the radiation and particulate matter on a long space voyage would have to have some massive and very powerful shielding.
<p>
It is theoretically possible to overcome all these obstacles, of course, but each obstacle makes it less and less likely that aliens have ever visited earth. I'm open to the possibility of aliens being here, and a part of me really hopes they are and that we'll find out for sure because that would be extremely cool. But I'm just very skeptical.
<p>
As far as the videos and things about aliens that have come out in the last few years, I've seen Mick West's attempts at explaining them, and I find all his explanations so convincing that it's safe to say in most case he <i>proved</i> that they are not aliens or highly advanced aerial spaceships of some kind. I'm not a UFO junky, so I haven't looked at everything that's out there, but I suspect what I haven't seen is probably just more of the same. Maybe some of it still defies explanation, but that doesn't mean it's aliens. It just means we don't know what it is.
<p>
I want to say one more thing just to be fair. There's this argument I've been hearing from other skeptics that goes something like this: It is unbelievable that an alien civilization so advanced that they could visit our planet would crash as much as David Grusch and others say they have. I think that's a poor argument for a couple of reasons.
<p>
First, the more difficult it is to complete a mission, then more failures we should expect there to be. When we advanced to the point of being able to drive cars instead of using horses and buggies, we starting having more accidents, not fewer. Traveling to Mars requires the most advanced technology we are capable of, yet half of all Mars missions end in failure. So the failure rate seems to go up as technology advances and as we attempt more and more difficult missions. A mission to another solar system is agreed by all to be extremely difficult, so why shouldn't we expect failures on the part of anybody who tries it? If we sent a thousand probes using solar sails to Proxima Centauri, should we expect that just because we were able to get there that we should also be able to land them all safely? Of course not. We shouldn't expect to land any of them at all. We should rather be lucky that a fraction make it there just to take some pictures before crashing or ending up in orbit somewhere.
<p>
A second reason I don't think the too-advanced-to-crash argument is a good argument is because without knowing how many aliens visitors we actually have, we have no idea what the crash rate is. 12 out of 50 is a much higher crash rate than 12 out of a million. If we grant that aliens are here, then we also have to grant that they have some kind of cloaking capabilities since they are so elusive. If they have some way of hiding, there could be millions for all we know, and 12 crashes is an extremely low crash rate. I see no reason to think any degree of technological advancement would give a species an infallible flying record.
<p>
Another bad argument I've heard from more than one skeptic is that a species advanced enough to travel here would be uninterested in visiting because we are so primitive that we are like ants to them. That's a terrible argument. We are planning to send probes to Europa and Enceledus in the desperate hope to find mere microbial life. Finding anything comparable to ant life would be wildly exciting. So even if we were like ants to another species, that doesn't mean we would be uninteresting to them. Also, the fact that they were more technologically advanced than us wouldn't mean they were any more intelligent than us. If we discovered something like cave men in the Proxima Centauri system, you can bet that we'd be pouring all our scientific and engineering efforts into sending a probe there to have a closer look.
<p>
I guess that's about all I have to say about alien stuff. I also think the incident in Las Vegas was a hoax that got out of hand.

I sometimes wonder, jokingly, whether there are really philosophical zombies among us. A philosophical zombie is a human being that behaves like any other human being except that it's all mechanical. There's no mind behind the behavior, no consciousness, etc. Philosophical zombies are just machines.
<p>
One reason I've wondered about this is because there are some serious philosophers who deny the existence of consciousness. I talked about that in <a href="https://philochristos.blogspot.com/2018/09/is-consciousness-illusion.html">this post</a>. Or some people seemed to be <a href="https://philochristos.blogspot.com/2021/03/what-is-consciousness.html">confused about what consciousness even is</a>. Anybody who is conscious knows they are conscious and what it means to be conscious, so anybody who denies these things or behaves as if they are confused about it might be a philosophical zombie.
<p>
There's another point of view out there--I think it's called analytical behaviorism--that tries to explain things like pain and desire purely in terms of behavior. For example, they might say that pain is just the tendency to say, "Ouch!" in certain situations. These people try to get away from using mental language at all. It's all just behavior. To me, that sounds exactly like what's going on with philosophical zombies. They just behave, but there's no felt experience of pain behind their expressions. There's no desire or motive behind anything they do; it's just mechanical action.
<p>
If there are really people who say that (I shy away from saying, "think that,"), then maybe it's because they really are philosophical zombies. Because otherwise, they'd know it wasn't true.
<p>
I suppose the one exception might be in the case of epiphenomenalists. These are people who believe in minds and consciousness, but they don't believe minds and consciousness have any influence over our behavior. Mental states are just the inert byproducts of processes in the brain. The brain gives rise to mental states, but the mental states don't give rise to behavior. The direction of causation (or entailment) only goes one way.
<p>
For all practical purposes, if epiphenomenalism were true (at least in the case of some people), then people are as good as philosophical zombies. We shouldn't expect that their behavior is indicative of anything that's going on in their minds. They could be saying and behaving one way while thinking and feelings something completely different. There's no reason in the world for evolution to have produced brains that generate minds and behaviors that correspond to each other since minds don't do anything. Smashing somebody's finger might actually feel good to them in spite of their crying out as if they were in pain. Their behavior is purely mechanical and can be accounted for purely in the language of physics and chemistry without reference to anything like desire, motive, belief, sensation, or feeling.
<p>
I don't actually believe there are philosophical zombies among us, but sometimes it seems like the only explanation for how people seem to seriously embrace these obviously false ideas. I say, "seem" because, of course, they don't really <i>believe</i> these things if they really are philosophical zombies. They're just behaving.

I recently saw a discussion/debate between <a href="https://www.youtube.com/watch?v=LVUQAVQS1-U">Bart Ehrman and Justin Bass</a> on YouTube. During the discussion, Ehrman made an interesting argument. He believes that Peter, Paul, James (the Lord's brother), and Mary Magdeline all saw something they took to be the risen Jesus. His explanation for why they interpreted it as the risen Jesus was because first century Jews didn't believe in ghosts, so any seeing of Jesus would've been interpreted as a bodily resurrected Jesus.
<p>
If Bart's argument is sound, it would undermine an argument I've been making for a long time. My argument is that grief hallucinations and things like that <i>never</i> lead to belief in resurrections, and given the emphasis in some of the Biblical accounts on the physicality of Jesus (e.g. touching him and him eating), it makes more sense to say their experience was different than a mere hallucination. They must've touched him and/or witnessed him eating or something that would cause them to think he had really risen from the dead because otherwise, they would've interpreted it as just a halluciation, vision, ghost, mistaken identity, dream, Jesus didn't die, etc. There were lots of other ways they'd be more likely to interpret what they saw if it were just a hallucination. Resurrection is the very last thing anybody would think if they saw somebody who appeared to be alive but who they knew had died. The fact that they came to that conclusion probably means they had some real convincing physical interaction with Jesus, just as the New Testament reports they did.
<p>
Given the way I've argued for Jesus' resurrection in the past, I found Bart's argument really interesting. But I have two problems with it. First, I don't think Bart is right that first century Jews didn't believe in ghosts. There are a few things that came to mind. First, I remember N.T. Wright going into some detail in his book on Jesus' resurrection about ancient beliefs about the afterlife, and although it's been a long time, I vaguely remember him saying first century Jews <i>did</i> believe in ghosts. My copy of his book is in storage right now, so I can't look it up to be sure.
<p>
Second, there are at least a couple of times in the New Testament when it says the disciples thought they were seeing or hearing a ghost. The first time was in Luke 24 when the disciples saw Jesus and thought at first that he was a ghost. The second time was in Acts 12 when Peter escaped from prison and knocked on the door where the disciples were hanging out. They assumed Peter had been killed, and it must be his ghost. Bart could answer that by saying Luke wasn't a Jew, and this represents a later belief of gentile Christians, not Jews. On the other hand, when Jesus walked on water, Mark 6 and Matthew 14 both say the disciples thought they were seeing a ghost at first. Mark's gospel certainly wasn't written by a gentile, and Matthew's probalby wasn't either.
<p>
Third, there's that passage in 1 Samuel 28 when Saul has the witch of Endor raise Samuel's ghost. It may have been unusual, but surely any Jew familiar with the story would believe there can be ghosts.
<p>
Fourth, Bart may be talking about the official Jewish beliefs held by professional Jewish teachers, not the popular beliefs of every day Jews. Sadduccees probably didn't believe in ghosts, but they didn't believe in resurrections either. I don't know about Pharisees. But considering how there were Jews living all over the Roman empire, and not just in Judea, and the fact that Greeks and most other cultures believed in ghosts, it seems very likely to me that ordinary Jews probably believed in ghosts. At least some of them did.
<p>
Fifth, a quick google search found multiple web pages claiming that ancient Jews did believe in ghosts.
<p>
Sixth, it at least appears in a few passages written by Paul (like 2 Corinthians 5:1-5 and 1 Thessalonians 4:13-14) that Paul believed in ghosts or at least a disembodied existence between death and resurrection. Since Paul was a well-educated first century Jew, that surely counts for something.
<p>
I will have to look into this subject a little more, but I strongly suspect Bart was just wrong to say first century Jews didn't believe in ghosts. I guess a seventh point might be that if someboddy saw a person they knew to be dead, that very experience could cause them to believe in ghosts even if they didn't believe in ghosts up to then.
<p>
The second problem I have with Bart's argument is that even if Bart is right that first century Jews didn't believe in ghosts, we still have to face the fact that grief hallucinations are fairly common, yet they never lead to belief that somebody has risen from the dead. If, as Bart says, the only way the disciples <i>could</i> have interpreted their experience was that Jesus had risen from the dead, and also, as Bart said, hallucinations of dead loved ones is fairly common, then we should expect first century Jews to believe people rose from the dead all the time. Yet that is not what we find. We find, instead, that they believed in a final general resurrection on the last day. So my original point would still stand even if Bart were right about Jews not believing in ghosts. There would still have to be something that was different in the case of the appearances of Jesus that would lead them to believe he had risen from the dead.
<p>
While Bart makes an interesting argument that I will probably look into and think about some more, right now I don't think it's a sound explanation for why Peter, James, Paul, and Mary Magdeline thought Jesus rose from the dead.

This morning I was thinking about that post I made a couple of days on <a href="https://philochristos.blogspot.com/2023/04/are-prophets-just-people-with.html">schizophrenia and prophecy</a>. There, I was talking specifically about how you might be able to tell whether some experience you had was a hallucination or not. It seems easier to rule visions, prophecies, etc. out than to rule them in. This morning, I was thinking about the problem more generally.
<p>
A person with schizophrenia might have all kinds of delusions and hallucinations. They're not limited to spiritual things. How might a person with schizophrenia tell whether they are seeing something that's really there or not? I'm not a psychiatrist or anything, but having read a lot about psychosis and schizophrenia, including testimonies from people who have it, I get the impression that for them, the hallucinations seem every bit as real as what the rest of us see on a daily basis. How do <i>we</i> know any of it is real? Maybe we <i>all</i> have schizophrenia, and none of this is real.
<p>
The problem of the external world comes from the fact that while it seems like we are more than reasonable in thinking that what our senses are telling us about what appears to be a world that exists outside of our minds is basically accurate, there's no way to prove it. It could all just be perception in our minds. I remember putting this problem to somebody one time, and him telling me, "Well, if I see a goat, and you tell me you see it, too, then I know there's a goat out there." But how does he know <i>I'm</i> out there? He's assuming the very thing that's under dispute. He only knows I'm out there telling him about the goat because he already trusts his sensory perception of me.
<p>
I've wrestled with that problem a lot and have come down on the side of weak foundationalism. There are just some items of knowledge that are built in. We don't infer them from anything else. They are a priori. We should assume things are basically like they appear to be unless we have really good reason to think otherwise. I've written about this in a few places.

This epistemology doesn't depend on our sensory perceptions be infallible. Even the most mentally healthy among us see mirages and illusions from time to time, and we have dreams that at least <i>seem</i> real while we're having them. Our senses can and do deceive us. My epistemology only depends on our senses being generally reliable.
<p>
But it would seem my epistemology could be problematic for somebody with schizophrenia. If they saw an elephant floating in the air in front of them all of a sudden, that elephant may seem every bit as real as the tree just off to the left that's really there. If they apply my thumb rule, they will assume the elephant is real until they have good reason to think otherwise.
<p>
If somebody with schizophrenia sees something strange, and the person next to them doesn't see it, that might provide them with good reason to think it's not really there. But then how can they be sure the person next to them is really there? Does this undermine my whole epistemology, or do we just have to make an exception in the case of people with schizophrenia? Can people with schizophrenia have a justified belief in what their senses are telling them? Does epistemology work differently for them?
<p>
This seems even more problematic when it comes to the subject of visions. According to the Bible, some people really do see visions that are inspired by God. It is likely that had anybody been with Daniel or Ezekiel when they had their visions, nobody else would've seen what they saw. Should they have concluded it was a hallucination if the person with them couldn't verify it? Or should they continue to affirm what seems obvious to them until an even better reason comes along that disconfirms it, like I talked about in my <a href="https://philochristos.blogspot.com/2023/04/are-prophets-just-people-with.html">last post</a>? If they are justified in believing the visions even if nobody else saw them, then are people with schizophrenia justified in believing their hallucinations until something comes along to disconfirm it?
<p>
I'm enclined to think a person with schizophrenia who doesn't know they have schizophrenia is justified in believing their hallucinations. It is possible to be justified in believing something that is false. But it also seems to me there are lots of ways a person with schizophrenia can discover that what they are seeing isn't real.
<p>
Plantinga has this thought experiment in which you see what appears to be a dog in a field, so you conclude it's a dog. But then you find out there's a pill that can make you think you're seeing a dog every time you look at a sheep. Moreover, you know you just took that pill, and your host just told you there's a sheep in the field. That would destroy any warrant for trusting your senses about what appears to be a dog. Well, finding out you have schizophrenia could be just like that scenario. You've discovered that your belief-producing cognitive faulties aren't working right, so you have reason to doubt them. But without that information, it seems to me you would've been justified in believing it was a dog you were seeing. In the same way, I think a person suffering from psychosis can be justified in believing what they are seeing if they don't know they have psychosis.
<p>
There are lots of good reasons a person with psychosis might have to doubt what they are seeing. They might doubt it because (1) the person with them doesn't see it, (2) it's very strange or unusual, or (3) they know they have psychosis. Unless I have psychosis and just don't know it yet, I don't know what it's like. While some of them say their hallucinations seem just as real as everything else, it makes me wonder how they can <i>ever</i> be sure of <i>anything</i>. But presumably they are. A lot of them are functioning okay by using their sensory perceptions. They're just seeing a lot of extra stuff. Some of them learn to distinguish between the real and the hallucination. It would be interesting to meet a weak foundationalist who knew they had schizophrenia to see what they would say about all these things.
