Let there be no purpose in friendship save the deepening of the spirit.

The greatest gift of life is friendship, and I have received it.

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Friends and good manners will carry you where money won't go.

An excellent man he has no enemies and none of his friends like him.

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