"Prohairesis In Epictetus’ Stoic Moral Theory"

3:30-5:00 pm Monday 10 October 2016

Location: Raynor Library 330b, third floor

Presentation Abstract

  Prohairesis In Epictetus’ Stoic Moral Theory

Abstract: Early on Stoics stressed “living in accordance with nature” as a central goal of their moral theory.  This theory also included a stress upon cultivating and actively living the virtues, upon happiness conceived of as apatheia and as freedom, and upon distinguishing between what are genuinely good, bad, and indifferent.

In the late Stoic Epictetus’ thought, “living in accordance with nature” is qualified and clarified as having or maintaining one’s “prohairesis in accordance with nature”.  This term prohairesis had already played a significant role in ancient moral theory and practice, for example in that of Aristotle, but Epictetus expands its scope considerably beyond that of earlier thinkers, so that it seems almost like a full conception of the faculty of will as found in later moral theories.

The main goal of the seminar is to examine selected passages from Epicetus’ Discourses bearing upon prohairesis.  We will focus upon four topics.  1) What the prohairesis is and how far it extends in Epictetus’ moral theory; 2) What it means to have one’s prohairesis in accordance with nature; 3) The relationship between prohairesis, the “rational faculty”, and the “ruling faculty”; 4) The reflexivity of the proharesis, and the means by which it determines or reshapes itself, particularly (re-)habituation.
