“It wasn't until late in life that I discovered how easy it is to say "I don't know.”

“It is cruel to discover one's mediocrity only when it is too late. It does not improve the temper.”

“I should have known that I wasn't meant for happiness and a life of ease. I have other work to do in the world.”

“Happily men don't realise how stupid they are, or half the world would commit suicide. Knowledge is a will-of-the-wisp, fluttering ever out of the traveller's reach; and a weary journey must be endured before it is even seen. It is only when a man knows a good deal that he discovers how unfathomable is his ignorance. The man who knows nothing is satisfied that there is nothing to know, consequently that he knows everything; and you may more easily persuade him that the moon is made of green cheese than that he is not omniscient.”

“I always find it more difficult to say the things I mean than the things I don't.”

“They ascribe omnipotence and omniscience to him and I don't know what else; it seems to me so strange that they never credit him with common-sense or allow him tolerance. If he knew as much about human nature as I do he'd know how weak men are and how little control they have over their passions, he'd know how full of fear they are and how pitiful, he'd know how much goodness there is even in the worst and how much wickedness in the best. If he's capable of feeling he must be capable of remorse, and when he considers what a hash he's made in the creation of human kind can he feel anything but that? The wonder is that he does not make use of his omnipotence to annihilate himself. Perhaps that's just what he has done.”

“The secret to life is meaningless unless you discover it yourself.”
