“Man is largely a creature of habit, and many of his activities are more or less automatic reflexes from the stimuli of his environment.”
“A human being has so many skins inside, covering the depths of the heart. We know so many things, but we don't know ourselves! Why, thirty or forty skins or hides, as thick and hard as an ox's or bear's, cover the soul. Go into your own ground and learn to know yourself there.”
