“For it is silly, my dear Lucilius, and no way for an educated man to behave, to spend one’s time exercising the biceps, broadening the neck and shoulders and developing the lungs. Even when the extra feeding has produced gratifying results and you’ve put on a lot of muscle, you’ll never match the strength or the weight of a prize ox. The greater load, moreover, on the body is crushing to the spirit and renders it less active. So keep the body within bounds as much as you can and make room for the spirit.”
