XXX. "Whatever I have bestowed upon my father," says my opponent, "however great it may be, yet is less valuable than what my father has bestowed upon me, because if he had not begotten me, it never could have existed at all." By this mode of reasoning, if a man has healed my father when ill, and at the point of death, I shall not be able to bestow anything upon him equivalent to what I have received from him; for had my father not been healed, he could not have begotten me. Yet think whether it be not nearer the truth to regard all that I can do, and all that I have done, as mine, due to my own powers and my own will? Consider what the fact of my birth is in itself; you will see that it is a small matter, the outcome of which is dubious, and that it may lead equally to good or to evil; no doubt it is the first step to everything, but because it is the first, it is not on that account more important than all the others. Suppose that I have saved my father's life, raised him to the highest honours, and made him the chief man in his city, that I have not merely made him illustrious by my own deeds, but have furnished him himself with an opportunity of performing great exploits, which is at once important, easy, and safe, as well as glorious; that I have loaded him with appointments, wealth, and all that attracts men's minds; still, even when I surpass all others, I am inferior to him. Now if you say, "You owe to your father the power of doing all this," I shall answer, "Quite true, if to do all this it is only necessary to be born; but if life is merely an unimportant factor in the art of living well, and if you have bestowed upon me only that which I have in common with wild beasts and the smallest, and some of the foulest of creatures, do not claim for yourself what did not come into being in consequence of the benefits which you bestowed, even though it could not have come into being without them."
