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

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

A man's friendships are one of the best measures of his worth.

The greatest gift of life is friendship, and I have received it.

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

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

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

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

If you have one true friend you have more than your share.

To like and dislike the same things, this is what makes a solid friendship.
