How can we know what we are told merely? Each man can interpret another's experience only by his own.

The only clue to what man can do is what he has done.

Experience is not what happens to a man; it is what a man does with what happens to him.

The only clue to what man can do is what man has done.

A man may imagine things that are false, but he can only understand things that are true.

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

No man knows fully what has shaped his own thinking

...you can only value something if you've experienced it.

Only the unknown frightens men. But once a man has faced the unknown, that terror becomes the known.

Man lives only to learn. And if he learns it is because it is the nature of his lot, for good or bad.

Experience is not what happens to a man; it is what a man does with what happens to him.” — ALDOUS HUXLEY

A man only learns in two ways, one by reading, and the other by association with smarter people.

A man who can't read only knows what other folks tell him.

The only source of knowledge is experience.
