“The man who comes back through the Door in the Wall will never be quite the same as the man who went out. He will be wiser but less sure, happier but less self-satisfied, humbler in acknowledging his ignorance yet better equipped to understand the relationship of words to things, of systematic reasoning to the unfathomable mystery which it tries, forever vainly, to comprehend”

“He was what men called a religious man, which in his case meant he was a superstitious man. There was never a man less Christian; there was never one who made a greater show of piety.”

“When a man is getting better he understands more and more clearly the evil that is still left in him. When a man is getting worse he understands his own badness less and less.”

“The more words, the more vanity, and what is man the better? For who knows what is good for man while he lives the few days of his vain life, which he passes like a shadow? For who can tell a man what shall be after him under the sun?”

“Any man who can take a TV wall apart and put it back together again, and most men can nowadays, is happier than any man who tries to slide-rule, measure, and equate the universe, which just won't be measured or equated without making man feel bestial and lonely.”

“Happy the man who lives long enough to acknowledge his ignorance”
