The most hopelessly stupid man is he who is not aware that he is wise.

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.

El hombre más irreversiblemente estúpido es aquel que ignora su sabiduría.

Most men are rather stupid, and most of those who are not stupid are, consequently, rather vain.

The most ignorant are the most conceited.

And he is oft the wisest man Who is not wise at all.

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

…I am a stupid, stupid man. I am a very, very dumb person. I…" [laughs in self-deprication] "He has an Auchenai Soulpriest! Why would you do that?! What is wrong with you?!

He seems to me a very foolish man, and very wretched, who will not increase his understanding while he is in the world, and ever wish and long to reach that endless life where all shall be made clear.

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.

The most ignorant are the most conceited. Unless a man knows that there is something more to be known, his inference is, of course, that he knows every thing. Such a man always usurps the throne of universal knowledge, and assumes the right of deciding all possible questions. We all know that a conceited dunce will decide questions extemporaneous which would puzzle a college of philosophers, or a bench of judges. Ignorant and shallow-minded men do not see far enough to see the difficulty. But let a man know that there are things to be known, of which he is ignorant, and it is so much carved out of his domain of universal knowledge. And for all purposes of individual character, as well as of social usefulness, it is quite as important for a man to know the extent of his own ignorance as it is to know any thing else. To know how much there is that we do not know, is one of the most valuable parts of our attainments; for such knowledge becomes both a lesson of humility and a stimulus to exertion.

Being stupid means avoiding thinking by jumping to conclusions.
