Real friendship, like real poetry, is extremely rare - and precious as a pearl.

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.

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

A man cannot be said to succeed in this life who does not satisfy one friend.

As iron sharpens iron, so a friend sharpens a friend.

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

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts.

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

I always felt that the great high privilege, relief and comfort of friendship was that one had to explain nothing.
