“[L]ove ought to manifest itself in deeds rather than in words.... love consists in a mutual sharing of goods, for example, the lover gives and shares with the beloved what he possesses, or something of that which he has or is able to give; and vice versa, the beloved shares with the lover. Hence, if one has knowledge, he shares it with the one who does not possess it; and so also if one has honors, or riches. Thus, one always gives to the other.”
