A man must be excessively stupid, as well as uncharitable, who believes that there is no virtue but on his own side, and that there are not men as honest as himself who may differ from him in political principles.

The most ignorant are the most conceited.

A man must be both stupid and uncharitable who believes there is no virtue or truth but on his own side.

Stay Stupid The three dumbest guys I can think of: Charles Lindbergh, Steve Jobs, Winston Churchill. Why? Because any smart person who understood how impossibly arduous were the tasks they had set themselves would have pulled the plug before he even began. Ignorance and arrogance are the artist and entrepreneur’s indispensable allies. She must be clueless enough to have no idea how difficult her enterprise is going to be — and cocky enough to believe she can pull it off anyway. How do we achieve this state of mind? By staying stupid. By not allowing ourselves to think. A child has no trouble believing the unbelievable, nor does the genius or the madman. It’s only you and I, with our big brains and our tiny hearts, who doubt and overthink and hesitate. Don’t think. Act.

He who knows not and knows not that he knows not is an incorrigible fool.

A man is responsible for his ignorance.

Being stupid means avoiding thinking by jumping to conclusions.

The idiot is indeed the good man, but only because he doesn't know any better.

A man who does not think for himself does not think at all.

The wisest man is generally he who thinks himself the least so.

He who knows he is a fool is not the biggest fool; he who knows he is confused is not in the worst confusion. The man in the worst confusion will end his life without ever getting straightened out; the biggest fool will end his life without ever seeing the light. If three men are traveling along and one is confused, they will still get where they are going - because confusion is in the minority. But if two of them are confused, then they can walk until they are exhausted and never get anywhere - because confusion is in the majority.

Most fools think they are only ignorant.

There are so many different kinds of stupidity, and cleverness is one of the worst.

Man is a most unwise, and a most wise, being. The individual is foolish. The multitude, for the moment, is foolish, when they act without deliberation; but the species is wise, and when time is given to it, as a species it almost always acts right.
