An ignorant person will never understand that he is ignorant. Please comment on this sentence? That's true. People have lived all their lives, and only when they die can they understand why they are alive and why they are alive. But there are also many people who are ignorant all their lives and don't understand when they die. Ignorant people will never think they are stupid. On the contrary, they will never pretend to understand. But many people have lost their way. So this sentence is still biased.

Socrates' words, God said I was the smartest in the world, probably because only I knew I was ignorant! Others are not the smartest because they all think they are smart.
