Book 3.31
Suppose, father, that I have saved your life, in return for the life which I received from you: in this case also I have outdone your benefit, because I have given life to one who understands what I have done, and because I understood what I was doing, since I gave you your life not for the sake of, or by the means of my own pleasure; for just as it is less terrible to die before one has time to fear death, so it is a much greater boon to preserve one's life than to receive it. I have given life to one who will at once enjoy it, you gave it to one who knew not if he should ever live; I have given life to one who was in fear of death, your gift of life merely enables me to die; I have given you a life complete, perfect; you begat me without intelligence, a burden upon others. Do you wish to know how far from a benefit it was to give life under such conditions? You should have exposed me as a child, for you did me a wrong in begetting me. What do I gather from this? That the cohabitation of a father and mother is the very least of benefits to their child, unless in addition this beginning of kindnesses be followed up by others, and confirmed by other services. It is not a good thing to live, but to live well. "But," say you, "I do live well." True, but I might have lived ill; so that your part in me is merely this, that I live. If you claim merit to yourself for giving me mere life, bare and helpless, and boast of it as a great boon, reflect that this you claim merit for giving me is a boon which I possess in common with flies and worms. In the next place, if I say no more than that I have applied myself to honourable pursuits, and have guided the course of my life along the path of rectitude, then you have received more from your benefit than you gave; for you gave me to myself ignorant and unlearned, and I have returned to you a son such as you would wish to have begotten.
