Aqui ficam algumas das belas palavras de Clemente de Alexandria sobre a amizade:
We are taught that there are three kinds of friendship: and that of these the first and the best is that which results from virtue, for the love that is founded on reason is firm; that the second and intermediate is by way of recompense, and is social, liberal, and useful for life; for the friendship which is the result of favour is mutual. And the third and last we assert to be that which is founded on intimacy; others, again, that it is that variable and changeable form which rests on pleasure. And Hippodamus the Pythagorean seems to me to describe friendships most admirably: “That founded on knowledge of the gods, that founded on the gifts of men, and that on the pleasures of animals.” There is the friendship of a philosopher,—that of a man and that of an animal.
