Prohairesis is a philosophical term referring to the human faculty of deliberate choice or will, first introduced by Aristotle and later central to Stoic philosophy, particularly Epictetus. It is the rational, moral capacity that allows individuals to assent to or withhold assent from impressions and make judgments about their actions. This faculty is considered the true self and is the only thing ultimately within our power, distinguishing humans from other beings and forming the basis for moral character and a virtuous life.

Prohairesis or proairesis (Ancient Greek: προαίρεσις; variously translated as "moral character", "will", "volition", "choice", "intention", or "moral choice"1(https://en.wikipedia.org/wiki/Prohairesis#cite_note-1)) is a fundamental concept in the Stoic philosophy of Epictetus. It represents the choice involved in giving or withholding assent to impressions (phantasiai). The use of this Greek word was first introduced into philosophy by Aristotle in the Nicomachean Ethics.2(https://en.wikipedia.org/wiki/Prohairesis#cite_note-2) To Epictetus, it is the faculty that distinguishes human beings from all other creatures. The concept of prohairesis plays a cardinal role in the Discourses and in the Manual: the terms "prohairesis", "prohairetic", and "aprohairetic" appear some 168 times.3(https://en.wikipedia.org/wiki/Prohairesis#cite_note-3)[[4]](https://en.wikipedia.org/wiki/Prohairesis#cite_note-4)
