“Those who receive the bare theories immediately want to spew them, as an upset stomach does its food. First digest your theories and you won’t throw them up. Otherwise they will be raw, spoiled, and not nourishing. After you’ve digested them, show us the changes in your reasoned choices, just like the shoulders of gymnasts display their diet and training, and as the craft of artisans show in what they’ve learned.”

—EPICTETUS, DISCOURSES, 3.21.1–3
