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

A man cannot be said to succeed in this life who does not satisfy one friend.

Friendship is the source of the greatest pleasures, and without friends even the most agreeable pursuits become tedious.

Nothing but heaven itself is better than a friend who is really a friend.

Accountability in friendship is the equivalent of love without strategy.

The language of friendship is not words but meanings

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

A friend is one who knows you and loves you just the same.

A friend may well be reckoned the masterpiece of nature.

A true friend never gets in your way unless you happen to be going down.
