“The whole problem with the world is that fools and fanatics are always so sure of themselves and wiser people so full of doubt.”

“The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence.”

“The problem with the wise is they are so filled with doubts and questions, while fools are so certain about things.”

“Only a fool humbles himself when the world is so full of men eager to do that job for him.”

“The people I know who thought brutal thoughts and acted in brutal ways - the racists, the sexists, the bigots - never seemed to doubt themselves. They were always sure that they were right... I almost envied them the strength of their beliefs. It must have made life so much easier for them.”

“Stop blaming me, thinking I'm the problem. If you think I'm the problem, then you have to change me. If you realize that you're the problem, then you can change yourself, learn something and grow wiser. Most people want everyone else in the world to change themselves. Let me tell you, it's easier to change yourself than everyone else.”
