Epictetus was a Greek philosopher of Stoicism who lived from 50-135AD. Born a slave, Epictetus was taught by Musonius Rufus, another Stoic philosopher. He was set free at some point in his life and from there became a teacher of philosophy, first in Rome, then in Greece. Like Socrates, Epictetus wrote little, if anything, in his lifetime and so the majority of Epictetus’ teachings are from his pupil Arrian.
In the Discourses, Epictetus focuses on the things which are in our control and the things which are not. Distinguishing between these two is crucial, and it is this distinction which is the first step to serenity. Epictetus prioritises the mind over the body (‘why do you attach yourself to what is mortal?’), and inherits the Platonic idea that the body is a hindrance to the mind (‘these chains attached to us-the body and its possessions’). Furthermore, the influence of Aristotle can be seen when Epictetus writes of one’s ‘proper end’ and of acting according the human nature-Epictetus seems to use natural law as an argument for how to act (through reasoning-phronesis).
A key idea of Epictetus is of the external and the internal. Most fundamentally, it is our own internal judgement and opinion which causes our acts and our world view, rather than the circumstances around us-he believes we have control over how we view the world and life in general (a main Stoic idea). He says that tragedy is the portrayal,, in tragic verse, of men who have ‘attached high value to external things’. We must not attach ourselves too greatly to the external, but rather focus on what is inside us. Moreover, he emphasises that rather than discussing principles and discussing certain actions, we should act and put our principles into action, as well as aiming to solve problems rather than to complain about them. The human good, Epictetus says, ‘lies in a certain quality of choice.’
