A wise man neither lets himself be governed nor seeks to govern others: he wishes reason alone to govern, and for ever.

[Un homme sage ni ne se laisse gouverner, ni ne cherche à gouverner les autres: il veut que la raison gouverne seule et toujours.]

Jean de La Bruyère (1645-1696) French essayist, moralist

The Characters [Les Caractères], ch. 4 “Of the Heart [Du Coeur],” § 71 (4.71) (1688) [tr. Stewart (1970)]
