When a cabdriver lied about a route, or a shopkeeper shortchanged me, I felt that it was my fault, for speaking Turkish with an accent, or for being part of an élite. And, if I pretended not to notice these slights, wasn’t I proving that I really was a disengaged, privileged oppressor? Epictetus shook me from these thoughts with this simple exercise: 'Starting with things of little value—a bit of spilled oil, a little stolen wine—repeat to yourself: "For such a small price, I buy tranquillity."'"
From "How to Be a Stoic/Born nearly two thousand years before Darwin and Freud, Epictetus seems to have anticipated a way out of their prisons," by Elif Batuman in The New Yorker).
What is she saying? I'm reading that to mean that what she learned from Epictetus is that she doesn't have to berate herself for being aloof when she pretends not to notice when people cheat her. She can think well of herself — a stoic, buying tranquillity* on the cheap. If you're going to let people get away with cheating, you might as well figure out how not to compound the injury by hating on yourself. By the way, Epictetus was a slave.
