True friendship ought never to conceal what it thinks.

It is only the great hearted who can be true friends. The mean and cowardly, Can never know what true friendship means.

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

One's friends are that part of the human race with which one can be human.

The language of friendship is not words but meanings

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

Depth of friendship does not depend on length of acquaintance.

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

Nothing so fortifies a friendship as a belief on the part of one friend that he is superior to the other.

Friendship is always a sweet responsibility, never an opportunity.
