But it seems that while love is a feeling, friendship is a habit or trained faculty. For inanimate things can equally well be the object of love, but the love of friends for one another implies purpose, and purpose proceeds from a habit or trained faculty. And in wishing well for their sakes to those they love, they are swayed not by feeling, but by habit. Again, in loving a friend they love what is good for themselves; for he who gains a good man for his friend gains something that is good for himself. Each then, loves what is good for himself, and what he gives in good wishes and pleasure is equal to what he gets; for love and equality, which are joined in the popular saying φιλότης ἰσότης , are found in the highest degree in the friendship of good men.
