20. Among all these things, then, those only are the true objects of enjoyment which we have spoken of as eternal and unchangeable. The rest are for use, that we may be able to arrive at the full enjoyment of the former. We, however, who enjoy and use other things are things ourselves. For a great thing truly is man, made after the image and similitude of God, not as respects the mortal body in which he is clothed, but as respects the rational soul by which he is exalted in honour above the beasts. And so it becomes an important question, whether men ought to enjoy, or to use, themselves, or to do both. For we are commanded to love one another: but it is a question whether man is to be loved by man for his own sake, or for the sake of something else. If it is for his own sake, we enjoy him; if it is for the sake of something else, we use him. It seems to me, then, that he is to be loved for the sake of something else. For if a thing is to be loved for its own sake, then in the enjoyment of it consists a happy life, the hope of which at least, if not yet the reality, is our comfort in the present time. But a curse is pronounced on him who places his hope in man.
