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. [Jer. 17. 5.]
