The 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 a graceful pride, an active and joyous bearing, and a contented and good-natured countenance. The surest sign of wisdom is constant cheerfulness.

Labour not after riches first, and think thou afterwards wilt enjoy them. He who neglecteth the present moment, throweth away all that he hath. As the arrow passeth through the heart, while the warrior knew not that it was coming; so shall his life be taken away before he knoweth that he hath it.
