Ses progrès dans la géométrie vous pourraient servir d'épreuve et de mesure certaine pour le développement de son intelligence : mais sitôt qu'il peut discerner ce qui est utile et ce qui ne l'est pas, il importe d'user de beaucoup de ménagement et d'art pour l'amener aux études spéculatives.

Such is the pure movement of nature prior to all reflection. Such is the force of natural pity, which the most depraved mores still have difficulty destroying, since everyday one sees in our theaters someone affected and weeping at the ills of some unfortunate person, and who, were he in the tyrant's place, would intensify the torments of his enemy still more; [like the bloodthirsty Sulla, so sensitive to ills he had not caused, or like Alexander of Pherae, who did not dare attend the performance of any tragedy, for fear of being seen weeping with Andromache and Priam, and yet who listened impassively to the cries of so many citizens who were killed everyday on his orders. Nature, in giving men tears, bears witness that she gave the human race the softest hearts.] Mandeville has a clear awareness that, with all their mores, men would never have been anything but monsters, if nature had not given them pity to aid their reason; but he has not seen that from this quality alone flow all the social virtues that he wants to deny in men. In fact, what are generosity, mercy, and humanity, if not pity applied to the weak, to the guilty, or to the human species in general. Benevolence and even friendship are, properly understood, the products of a constant pity fixed on a particular object; for is desiring that someone not suffer anything but desiring that he be happy?
