If each man bestows benefits upon himself, is always bestowing them, and bestows them without any cessation, then it is impossible for him to make any calculation of the number of his benefits; when then can he show his gratitude, seeing that by the very act of doing so he would bestow a benefit? for what distinction can you draw between giving himself a benefit or receiving a benefit for himself, when the whole transaction takes place in the mind of the same man? Suppose that I have freed myself from danger, then I have bestowed a benefit upon myself; suppose I free myself a second time, by so doing do I bestow or repay a benefit? In the next place, even if I grant the primary axiom, that we can bestow benefits upon ourselves, I do not admit that which follows; for even if we can do so, we ought not to do so. Wherefore? Because we receive a return for them at once. It is right for me to receive a benefit, then to lie under an obligation, then to repay it; now here there is no time for remaining under an obligation, because we receive the return without any delay. No one really gives except to another, no one owes except to another, no one repays except to another. An act which always requires two persons cannot take place within the mind of one.
