It is granted that many sons become greater and more powerful than their parents, and also that they are better men. If this be true, they may give better gifts to their fathers than they have received from them, seeing that their fortune and their good nature are alike greater than that of their father. “Whatever a father receives from his son,” our opponent will urge, “must in any case be less than what the son received from him, because the son owes to his father the very power of giving. Therefore the father can never be surpassed in the bestowal of benefits, because the benefit which surpasses his own is really his.” I answer, that some things derive their first origin from others, yet are greater than those others; and a thing may be greater than that from which it took its rise, although without that thing to start from it never could have grown so great. All things greatly outgrow their beginnings. Seeds are the causes of all things, and yet are the smallest part of the things which they produce. Look at the Rhine, or the Euphrates, or any other famous rivers; how small they are, if you only view them at the place from whence they take their rise? they gain all that makes them terrible and renowned as they flow along.
