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

The most I can do for my friend is simply be his friend.

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

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

Depth of friendship does not depend on length of acquaintance.

Peace, commerce and honest friendship with all nations entangling alliances with none.

A friend may well be reckoned the masterpiece of nature.

Friendship is always a sweet responsibility, never an opportunity.

I don't need a friend who changes when I change and who nods when I nod my shadow does that much better.

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