The most I can do for my friend is simply be his friend.

There is nothing on this earth more to be prized than true friendship.

Never contract friendship with a man that is not better than thyself.

An insincere and evil friend is more to be feared than a wild beast a wild beast may wound your body, but an evil friend will wound your mind.

Accountability in friendship is the equivalent of love without strategy.

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

Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.

That friendship will not continue to the end which is begun for an end.

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

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