La plus grande chose du monde, c'est de savoir être à soi. - Michel de Montaigne

Wherever your life ends, it is all there. The utility of living consists not in the length of days, but in the use of time; a man may have lived long, and yet lived but a little. Make use of time while it is present with you. It depends upon your will, and not upon the number of days, to have a sufficient length of life.

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.

There is, nevertheless, a certain respect and a general duty of humanity that ties us, not only to beasts that have life and sense, but even to trees and plants.
