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

One's friends are that part of the human race with which one can be human.

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

Each friend represents a world in us, a world not born until they arrive, and it is only by this meeting that a new world is born.

When the world is so complicated, the simple gift of friendship is within all of our hands.

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

Never explain - your friends do not need it and your enemies will not believe you anyway.

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

Be slow to fall into friendship but when thou art in, continue firm and constant.

Friendship is always a sweet responsibility, never an opportunity.
