Abstract
In this chapter, I explore Seneca’s characterization of becoming and being good, wise, or virtuous, which for a Stoic always amount to the same thing. There is one passage in which Seneca says it is an ars to become good; in another, he says wisdom is an ars, namely an ars vitae. If one bears in mind that wisdom in Stoic philosophy stands for the best possible moral state of character a human being can develop, Seneca’s remarks cannot but attract our attention: it is an ars to become good and an ars to be good. Since it is natural to regard becoming and being (good) as two different things, it is natural to assume that the ars of the person who is striving after virtue (the proficiens) cannot be identical to the ars of the person who already is virtuous. I want to ask what the difference is.
