a fundamental concept in the Stoic philosophy of Epictetus. It represents the choice involved in giving or withholding assent to impressions.
According to Epictetus, nothing is properly considered either good, or bad, aside from those things that are within our own power to control, and the only thing fully in our power to control is our own volition (prohairesis) which exercises the faculty of choice that we use to judge our impressions.
You’re here because you know something. What you know you can’t explain, but you feel it. You’ve felt it your entire life, that there’s something wrong with the world. You don’t know what it is, but it’s there, like a splinter in your mind, driving you mad.
