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

In friendship as well as love, ignorance very often contributes more to our happiness than knowledge.

True friendship ought never to conceal what it thinks.

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

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

Even where friendship is concerned, it takes me a long time to trust people.

Be true to your work, your word, and your friend.

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

No person is your friend who demands your silence, or denies your right to grow.
