One has a right to judge a man by the effect he has over his friends.

Anybody can sympathize with the sufferings of a friend, but it requires a very fine nature it requires, in fact, that nature of a true Individualist to sympathize with a friend's success.

A true friend stabs you in the front.

But what is the good of friendship if one cannot say exactly what one means? Anybody can say charming things and try to please and to flatter, but a true friend always says unpleasant things, and does not mind giving pain. Indeed, if he is a really true friend he prefers it, for he knows that then he is doing good.

Ultimately the bond of all companionship, whether in marriage or in friendship, is conversation...

Every impulse we strangle will only poison us.
