Thus they are destitute of that very lovely and exquisitely natural friendship, which is an object of desire in itself and for itself, nor can they learn from themselves how valuable and powerful such a friendship is. For each man loves himself, not that he may get from himself some reward for his own affection, but because each one is of himself dear to himself. And unless this same feeling be transferred to friendship, a true friend will never be found; for a true friend is one who is, as it were, a second self.Section 80; translation by J. F. Stout
