Abstract

The notion of prohairesis is one of the key notions of Epictetus’ Stoicism. While this notion was of minor importance in ancient Stoicism, being a kind of impulse consis­ting of a « choice before a choice » and was rarely associated with a broader meaning (to the noteworthy exception of Diogenes of Seleucia), Epictetus borrowed from Aristotelian philosophy a notion of prohairesis as a preferential choice strictly bound to the notion of eph’ hemin (« what depends on us »). But Epictetus introduced numerous alterations within the Aristotelian concept, extending its scope to all the active faculties of soul, including assent, and making prohairesis the only thing which depends on us, and not a choice concerning what depends on us, as is the case in Aristotle. A close analysis of the various senses of prohairesis in Epictetus shows that the word applies alternatively to cases of decision, to the faculty of making decisions, and, in a more restricted sense, to the preliminary choice of a way of life. Therefore, prohairesis is not strictly speaking a « moral person », as is often assumed, but contributes to constitute her, being the essence of good and evil.
