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

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

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

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

True friendship is like sound health the value of it is seldom known until it is lost.

Friendship may, and often does, grow into love, but love never subsides into friendship.

Nothing so fortifies a friendship as a belief on the part of one friend that he is superior to the other.

Friendship multiplies the good of life and divides the evil.

Friendship is always a sweet responsibility, never an opportunity.

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