A man never knows exactly how the child of his brain will strike other people.

What a man does not know is greater than he.

He lost himself in a maze of thoughts that were rendered vague by his lack of words to express them. Frowning, he tried again.

It is my belief no man ever understands quite his own artful dodges to escape from the grim shadow of self-knowledge.

A man doesn't know what he knows until he knows what he doesn't know.

Man can embody truth but he cannot know it.

A guy sets alone out here at night, maybe readin' books or thinkin' or stuff like that. Sometimes he gets thinkin', an' he got nothing to tell him what's so an' what ain't so. Maybe if he sees somethin', he don't know whether it's right or not. He can't turn to some other guy and ast him if he sees it too. He can't tell. He got nothing to measure by.

Man can embody the truth but he cannot know it.

He doesn't know what he means, and doesn't know he doesn't know.

No man knows where his business ends and his neighbor's begins.

Dreaming men are haunted men.

Man is certain of nothing but his ability to fail

A man who knows how little he knows is well, a man who knows how much he knows is sick.

Mankind is connected in ways it does not understand - even in dreams.
