Abstract
In this chapter, I argue that Plato and Aristotle provide analyses of virtue and practical reason that are strongly shaped by the structure of the technai. Socrates assimilates virtue to skill, while Aristotle assimilates practical reason to a means-end technique. While both philosophers are sensitive to the problems these technē models generate, and try either to escape or to remedy them, they nonetheless remain under the impress of those models. I end by drawing a general lesson from this fascinating episode in intellectual history.
