Rejoicing in our joy, not suffering over our suffering, makes someone a friend.

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

Nothing but heaven itself is better than a friend who is really a friend.

Am I not destroying my enemies when I make friends of them?

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

Never explain - your friends do not need it and your enemies will not believe you anyway.

The bird a nest, the spider a web, man friendship

A man's growth is seen in the successive choirs of his friends.

A true friend is someone who is there for you when he'd rather be anywhere else.

Friendship is the source of the greatest pleasures, and without friends even the most agreeable pursuits become tedious.
