But nobility is itself exhibited in choosing and practising what is best. For what benefit to Adam was such a nobility as he had? No mortal was his father; for he himself was father of men that are born. What is base he readily chose, following his wife, and neglected what is true and good; on which account he exchanged his immortal life for a mortal life, but not for ever. And Noah, whose origin was not the same as Adam’s, was saved by divine care. For he took and consecrated himself to God. And Abraham, who had children by three wives, not for the indulgence of pleasure, but in the hope, as I think, of multiplying the race at the first, was succeeded by one alone, who was heir of his father’s blessings, while the rest were separated from the family; and of the twins who sprang from him, the younger having won his father’s favour and received his prayers, became heir, and the elder served him. For it is the greatest boon to a bad man not to be master of himself.
