As for how we are to prove that the wise man possesses all things, we shall see afterwards; for the present we are both agreed to regard this as true; we must gather together something to answer the question before us, which is, how any means remain of acting generously towards one who already possesses all things? All things that a son has belong to his father, yet who does not know that in spite of this a son can make presents to his father? All things belong to the gods; yet we make presents and bestow alms even upon the gods. What I have is not necessarily not mine because it belongs to you; for the same thing may belong both to me and to you.
