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

There is nothing on this earth more to be prized than true friendship.

It is more shameful to distrust our friends than to be deceived by them.

Friendship... is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.

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

An excellent man he has no enemies and none of his friends like him.

When the world is so complicated, the simple gift of friendship is within all of our hands.

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

Friendship, like the immortality of the soul, is too good to be believed.

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