Never explain - your friends do not need it and your enemies will not believe you anyway.

That friendship will not continue to the end which is begun for an end.

A true friend is the greatest of all blessings, and that which we take the least care of all to acquire.

Am I not destroying my enemies when I make friends of them?

Accountability in friendship is the equivalent of love without strategy.

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

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

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

Let there be no purpose in friendship save the deepening of the spirit.

It is important to our friends to believe that we are unreservedly frank with them, and important to friendship that we are not.
