“Though it may be the peculiar happiness of Socrates and other geniuses of his stamp, to reason themselves into virtue, the human species would long ago have ceased to exist, had it depended entirely for its preservation on the reasonings of the individuals that compose it." Par 1, 36”

“There is, I am sensible, an age at which every individual of you would choose to stop; and you will look out for the age at which, had you your wish, your species had stopped. Uneasy at your present condition for reasons which threaten your unhappy posterity with still greater uneasiness, you will perhaps wish it were in your power to go back; and this sentiment ought to be considered, as the panegyric of your first parents, the condemnation of you contemporaries, and a source of terror to all those who may have the misfortune of succeeding you.”

“Man’s first law is to watch over his own preservation; his first care he owes to himself; and as soon as he reaches the age of reason, he becomes the only judge of the best means to preserve himself; he becomes his own master.”

“Teach your scholar to observe the phenomena of nature; you will soon rouse his curiosity, but if you would have it grow, do not be in too great a hurry to satisfy this curiosity. Put the problems before him and let him solve them himself. Let him know nothing because you have told him, but because he has learnt it for himself. Let him not be taught science, let him discover it. If ever you substitute authority for reason he will cease to reason; he will be a mere plaything of other people's thoughts.”

“It is reason which breeds pride and reflection which fortifies it; reason which turns man inward into himself; reason which separates him from everything which troubles or affects him. It is philosophy which isolates a man, and prompts him to say in secret at the sight of another suffering: 'Perish if you will; I am safe.' No longer can anything but dangers to society in general disturb the tranquil sleep of the philosopher or drag him from his bed. A fellow-man may with impunity be murdered under his window, for the philosopher has only to put his hands over his ears and argue a little with himself to prevent nature, which rebels inside him, from making him identify himself with the victim of the murder. The savage man entirely lacks this admirable talent, and for want of wisdom and reason he always responds recklessly to the first promptings of human feeling.”

“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?”

“The imagination which causes so many ravages among us, never speaks to the heart of savages" Pt.1, 41”
