“They say that Caliph Omar, when consulted about what had to be done with the library of Alexandria, answered as follows: 'If the books of this library contain matters opposed to the Koran, they are bad and must be burned. If they contain only the doctrine of the Koran, burn them anyway, for they are superfluous.' Our learned men have cited this reasoning as the height of absurdity. However, suppose Gregory the Great was there instead of Omar and the Gospel instead of the Koran. The library would still have been burned, and that might well have been the finest moment in the life of this illustrious pontiff.”

“I don't know how this lively and dumb scene would have ended , or how long I might have remained immoveable in this ridiculous and delightful situation , had we not been interrupted.”

“My illusions about the world caused me to think that in order to benefit by my reading I ought to possess all the knowledge the book presupposed. I was very far indeed from imagining that often the author did not possess it himself, but had extracted it from other books, as and when he needed it. This foolish conviction forced me to stop every moment, and to rush incessantly from one book to another; sometimes before coming to the tenth page of the one I was trying to read I should, by this extravagant method, have had to run through whole libraries. Nevertheless I stuck to it so persistently that I wasted infinite time, and my head became so confused that I could hardly see or take in anything.”

“The extreme inequality of our ways of life, the excess of idleness among some and the excess of toil among others, the ease of stimulating and gratifying our appetites and our senses, the over-elaborate foods of the rich, which inflame and overwhelm them with indigestion, the bad food of the poor, which they often go withotu altogether, so hat they over-eat greedily when they have the opportunity; those late nights, excesses of all kinds, immoderate transports of every passion, fatigue, exhaustion of mind, the innumerable sorrows and anxieties that people in all classes suffer, and by which the human soul is constantly tormented: these are the fatal proofs that most of our ills are of our own making, and that we might have avoided nearly all of them if only we had adhered to the simple, unchanging and solitary way of life that nature ordained for us. ”

“...there is no real advance in human reason, for what we gain in one direction we lose in another; for all minds start from the same point, and as the time spent in learning what others have thought is so much time lost in learning to think for ourselves, we have more acquired knowledge and less vigor of mind. Our minds like our arms are accustomed to use tools for everything, and to do nothing for themselves.”

“In truth, laws are always useful to those with possessions and harmful to those who have nothing; from which it follows that the social state is advantageous to men only when all possess something and none has too much.”

“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?”
