What is a friend? A single soul dwelling in two bodies.

Wishing to be friends is quick work, but friendship is a slow ripening fruit.

A friend to all is a friend to none.

The antidote for fifty enemies is one friend.

Without friends, no one would want to live, even if he had all other goods.

Distance does not break off the friendship absolutely, but only the activity of it.

My best friend is the man who in wishing me well wishes it for my sake.

For though we love both the truth and our friends, piety requires us to honor the truth first.

All friendly feelings toward others come from the friendly feelings a person has for himself.
