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

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

One of the most beautiful qualities of true friendship is to understand and to be understood.

There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

Friendship is something that creates equality and mutuality, not a reward for finding equality or a way of intensifying existing mutuality.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

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

Be true to your work, your word, and your friend.

Instead of loving your enemies - treat your friends a little better.

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