De parasito sive artem esse parasiticam

This is not the case, however, with Parasitic. Both among Greeks and among foreigners it is one and uniform and consistent, and nobody can say that it is practised in one way by this set of men and in another by that set. Nor are there, it seems, among parasites any sects like the Stoics or the Epicureans, holding different doctrines; no, there is concord among them all, and agreement in their works and in their end. So to my thinking Parasitic may well be, in this respect at least, actually wisdom.
