“The more stupid one is, the closer one is to reality. The more stupid one is, the clearer one is. Stupidity is brief and artless, while intelligence squirms and hides itself. Intelligence is unprincipled, but stupidity is honest and straightforward.”

“Stupidity is honest and straightforward.”

“I suspect gentlemen, that you're regarding me with pity; you keep repeating to me that an enlightened and cultured man -- such as, in short, as the man of the future will be -- cannot knowingly desire anything unprofitable for himself -- that that's mathematics. I agree totally that it really is mathematics. But I repeat to you for the hundredth time: there is only one case, only one, when a man can intentionally and consciously desire for himself even what is harmful and stupid, even what is extremely stupid: namely, in order to have the right to desire for himself even what is extremely stupid and not be constrained by the obligation to desire for himself only what is intelligent.”

“You see I kept asking myself then: why am I so stupid that if others are stupid—and I know they are—yet I won't be wiser?”

“It takes something more than intelligence to act intelligently.”

“I repeat, I repeat with emphasis: all "direct" persons and men of action are active just because they are stupid and limited. How explain that? I will tell you: in consequence of their limitation they take immediate and secondary causes for primary ones, and in that way persuade themselves more quickly and easily than other people do that they have found an infallible foundation for their activity, and their minds are at ease and you know that is the chief thing.”

“And a real, undoubted grief is sometimes capable of making a solid and steadfast man even out of a phenomenally light-minded one, if only for a short time; moreover, real and true grief has sometimes even made fools more intelligent, also only for a time, of course; grief has this property.”
