Friendship multiplies the good of life and divides the evil.

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

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

Be courteous to all, but intimate with few, and let those few be well tried before you give them your confidence.

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

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.
