Relativity in Stoic physics, metaphysics, and ethics

Abstract

This chapter argues that the two Stoic notions of relativity influenced Stoic discussions in physics, metaphysics, and ethics. Differentiated relatives pertain to Stoic physics, especially the basic physics of active and passive principles. Relatively disposed things connect to Stoic metaphysics, especially the Stoic categories. The relatively disposed also clarifies a well-known debate within the Stoa on the unity of the virtues. The chapter goes on to discuss some possible counter-evidence to my claim that Stoic relatives are objects, and compares the Stoic view of relativity with earlier views we found in Plato and Aristotle, especially concerning formal features like reciprocity and symmetry principles.
