The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
L'homme raisonnable s'adapte au monde; l'homme déraisonnable persiste à vouloir adapter le monde à lui-même. C'est pourquoi le progrès ne peut venir que de ce dernier.
It is in vain to hope to please all alike. Let a man stand with his face in what direction he will, he must necessarily turn his back on one half of the world.
