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

Friendship without self-interest is one of the rare and beautiful things of life.

Friends... they cherish one another's dreams. They are kind to one another's dreams

Caring for but never trying to own may be a further way to define friendship.

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

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

Friends... they cherish one another's hopes. They are kind to one another's dreams.

I always felt that the great high privilege, relief and comfort of friendship was that one had to explain nothing.

I value the friend who for me finds time on his calendar, but I cherish the friend who for me does not consult his calendar.

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