“We know very little, and yet it is astonishing that we know so much, and still more astonishing that so little knowledge can give us so much power.”

“Science tells us what we can know, but what we can know is little, and if we forget how much we cannot know we become insensitive to many things of very great importance.”

“the great world, so far as we know it from philosophy of nature, is neither good nor bad, and is not concerned to make us happy or unhappy. All such philosophies spring from self-importance, and are best corrected by a little astronomy.”

“You all know the argument from design: everything in the world is made just so that we can manage to live in the world, and if the world was ever so little different, we could not manage to live in it. That is the argument from design. It sometimes takes a rather curious form; for instance, it is argued that rabbits have white tails in order to be easy to shoot. I do not know how rabbits would view that application.”

“I feel as if one would only discover on one's death-bed what one ought to have lived for, and realise too late that one's life has been wasted. Any passionate and courageous life seems good in itself, yet one feels that some element of delusion is involved in giving so much passion to any humanly attainable object. And so irony creeps into the very springs of one's being.”

“The universe may have a purpose, but nothing we know suggests that, if so, this purpose has any similarity to ours.”

“We do not like to be robbed of an enemy; we want someone to hate when we suffer. It is so depressing to think that we suffer because we are fools; yet, taking mankind in the mass, that is the truth.”
