As iron sharpens iron, so a friend sharpens a friend.

An insincere and evil friend is more to be feared than a wild beast a wild beast may wound your body, but an evil friend will wound your mind.

Friendship without self-interest is one of the rare and beautiful things of life.

Never contract friendship with a man that is not better than thyself.

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

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

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

It is not so much our friends' help that helps us, as the confidence of their help.

Friendship is always a sweet responsibility, never an opportunity.

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