AThe soul in which philosophy dwells should by its health make even the body healthy. It should make its tranquillity and gladness shine out from within; should form in its own mold the outward demeanor, and consequently arm it with graceful pride, an active and joyous bearing, and a contented and good-natured countenance. CThe surest sign of wisdom is constant cheerfulness; her state is like that of things above the moon, ever serene.
