Abstract

The presence of slavery in Plato’s political and ethical thought is marked by two contrary tendencies: one signals the conventional character of statutory slavery and tends to reduce the moral boundary between free people and servile people; the other one, going in the opposite direction, strongly reaffirms the functional frontier between these two categories, and makes it impassable. What does this double gesture of integration and exclusion of slavery mean with respect to Plato’s political thought? My claim, based on the analysis of a passage in Book vi of the Laws and some excerpts from the Statesman, is the following: for Plato, the statutory slavery fulfills the function of drawing the inner civic boundary on which the political field must be built if it is to have a true conceptual autonomy, by contrast with what contributes to its construction but without being fully political.
