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

Friendship is a plant of slow growth and must undergo and withstand the shocks of adversity before it is entitled to the appellation.

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

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Cherish your human connections: your relationships with friends and family.

Since there is nothing so well worth having as friends, never lose a chance to make them.

Sweet is the memory of distant friends! Like the mellow rays of the departing sun, it falls tenderly, yet sadly, on the heart.

Let there be no purpose in friendship save the deepening of the spirit.

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

Friendship multiplies the good of life and divides the evil.
