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

The language of friendship is not words but meanings

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

Sweet is the memory of distant friends! Like the mellow rays of the departing sun, it falls tenderly, yet sadly, on the heart.

Accountability in friendship is the equivalent of love without strategy.

Since there is nothing so well worth having as friends, never lose a chance to make them.

Friendship, of itself a holy tie, is made more sacred by adversity.

Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

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

The friend is the man who knows all about you, and still likes you.
