My daughter, Grace, is 8 years old. I've been trying to teach her logic and careful thinking since she was born. One issue in particular that I've taught her about is the law of non-contradiction, and to illustrate it, I often ask her if she can draw a square circle. I told her the reason it's impossible is because it entails a contradictions, and real contradictions can't exist in reality.
Well this weekend, she wanted to prove to me that there could be such a thing as a square circle. She painted this picture to prove it.
