Wisdom and Joy

A cheery thought from Michel de Montaigne (1533-1592):

The surest sign of Wisdom
  is constant cheerfulness

... or more literally, "The most manifest sign of wisdom is a continual cheerfulness; her state is like that in the regions above the moon, always clear and serene." (La plus expresse marque de la sagesse, c'est un ejouïssance constante; son estat est comme des choses au dessus de la Lune: toujours serein.)
