Seek for doctrines which are consistent with what I say, and by making them your guide you will with pleasure abstain from things which have such persuasive power to lead us and overpower us. But if to the persuasive power of these things, we also devise such a philosophy as this which helps to push us on towards them and strengthens us to this end, what will be the consequence? In a piece of toreutic art which is the best part? the silver or the workmanship? The substance of the hand is the flesh; but the work of the hand is the principal part (that which precedes and leads the rest). The duties then are also three: those which are directed towards the existence of a thing; those which are directed towards its existence in a particular kind; and third, the chief or leading things themselves. So also in man we ought not to value the material, the poor flesh, but the principal (leading things, [Greek: ta proaegoumena]). What are these? Engaging in public business, marrying, begetting children, venerating God, taking care of parents, and generally, having desires, aversions ([Greek: echchlinein]), pursuits of things and avoidances, in the way in which we ought to do these things, and according to our nature. And how are we constituted by nature? Free, noble, modest; for what other animal blushes? what other is capable of receiving the appearance (the impression) of shame? and we are so constituted by nature as to subject pleasure to these things, as a minister, a servant, in order that it may call forth our activity, in order that it may keep us constant in acts which are conformable to nature.
