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.
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.
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.
