Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

A friend is one who knows you and loves you just the same.

He has no enemies, but is intensely disliked by his friends.

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.

Friendship at first sight, like love at first sight, is said to be the only truth.

A quarrel between friends, when made up, adds a new tie to friendship.

Friendship, like the immortality of the soul, is too good to be believed.

Friendship with ones self is all important, because without it one cannot be friends with anyone else in the world.

A friend is someone who gives you total freedom to be yourself.

True friendship can afford true knowledge. It does not depend on darkness and ignorance.
