Eros will have naked bodies; Friendship naked personalities. - C. S. Lewis

And Nothing is very strong: strong enough to steal away a man's best years not in sweet sins but in a dreary flickering of the mind over it knows not what and knows not why, in the gratification of curiosities so feeble that the man is only half aware of them, in drumming of fingers and kicking of heels, in whistling tunes that he does not like, or in the long, dim labyrinth of reveries that have not even lust or ambition to give them a relish, but which, once chance association has started them, the creature is too weak and fuddled to shake off.

A proud man is always looking down on things and people: and, of course, as long as you are looking down, you cannot see something that is above you.

If no set of moral ideas were truer or better than any other, there would be no sense in preferring civilised morality to savage morality.
