“It is one of the severest tests of friendship to tell your friend his faults. So to love a man that you cannot bear to see a stain upon him, and to speak painful truth through loving words, that is friendship.”

“Friendship is held to be the severest test of character. It is easy, we think, to be loyal to a family and clan, whose blood is in your own veins.”

“Always, Sir, set a high value on spontaneous kindness. He whose inclination prompts him to cultivate your friendship of his own accord, will love you more than one whom you have been at pains to attach to you.”

“Son, you're probably too young to look for wisdom in anyone's words but your own, but I'll tell you this: love is the enemy… Yes. The poets continually and sometimes willfully mistake love. Love is the old slaughterer. Love is not blind. Love is a cannibal with extremely acute vision. Love is insectile; it is always hungry.
When asked what love eats:
Friendship. It eats friendship.”

“The only way to tell the truth is to speak with kindness. Only the words of a loving man can be heard.”

“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.”
Ita pulcherrima illa et maxime naturali carent amicitia per se et propter se expetita nec ipsi sibi exemplo sunt, haec vis amicitiae et qualis et quanta sit. Ipse enim se quisque diligit, non ut aliquam a se ipse mercedem exigat caritatis suae, sed quod per se sibi quisque carus est. Quod nisi idem in amicitiam transferetur, verus amicus numquam reperietur; est enim is qui est tamquam alter idem.

“It is love and friendship, the sanctity and celebration of our relationships, that not only support a good life, but create one. Through friendships, we spark and inspire one another's ambitions.”

“Friendship often ends in love; but love in friendship—never.”

“Friendship often ends in love, but love in friendship - never.”

“There is something in the unselfish and self-sacrificing love of a brute, which goes directly to the heart of him who has had frequent occasion to test the paltry friendship and gossamer fidelity of mere Man.”
