OUR MOST IMPORTANT CHOICE in life, according to Epictetus, is whether to concern ourselves with things external to us or things internal. Most people choose the former because they think harms and benefits come from outside themselves. According to Epictetus, though, a philosopher—by which he means someone who has an understanding of Stoic philosophy—will do just the opposite. He will look “for all benefit and harm to come from himself.”1 In particular, he will give up the rewards the external world has to offer in order to gain “tranquility, freedom, and calm.”2
