“I never make stupid mistakes - only very, very clever ones.”

“Because of the self-confidence with which he had spoken, no one could tell whether what he said was very clever or very stupid.”

“But clever people all make one mistake. They all think everyone else is stupid. And everyone isn't stupid. They just take a bit more time, that's all.”

“A stupid person can make only certain, limited types of errors; the mistakes open to a clever fellow are far broader. But to the one who knows how smart he is compared to everyone else, the possibilities for true idiocy are boundless.”

“Between a stupid fascist and an intelligent fascist, prefer the intelligent one, because there is always a chance to persuade the clever one about the mistakes of his actions! There is no such a chance for stupid and ignorant fascist!”

“[Chess] is a foolish expedient for making idle people believe they are doing something very clever, when they are only wasting their time. ”
