The word “to owe” has no meaning except as between two persons; how then can it apply to one man who incurs an obligation, and by the same act frees himself from it? In a disk or a ball there is no top or bottom, no beginning or end, because the relation of the parts is changed when it moves, what was behind coming before, and what went down on one side coming up on the other, so that all the parts, in whatever direction they may move, come back to the same position. Imagine that the same thing takes place in a man; into however many pieces you may divide him, he remains one. If he strikes himself, he has no one to call to account for the insult; if he binds himself and locks himself up, he cannot demand damages; if he bestows a benefit upon himself, he straightaway returns it to the giver. It is said that there is no waste in nature, because everything which is taken from nature returns to her again, and nothing can perish, because it cannot fall out of nature, but goes round again to the point from whence it started. You ask, “What connection has this illustration with the subject?” I will tell you. Imagine yourself to be ungrateful; the benefit bestowed upon you is not lost, he who gave it has it; suppose that you are unwilling to receive it, it still belongs to you before it is returned.
