"I think that if there were a God, there would be less evil on this earth. I believe that if evil exists here below, then either it was willed by God or it was beyond His powers to prevent it. Now I cannot bring myself to fear a God who is either spiteful or weak. I defy Him without fear and care not a fig for his thunderbolts."

“Never will a free man bow to the gods of Christianity; never will its dogmas, never will its rites, never its mysteries, never its morals be suitable for a republican.”

“Voluptuaries of all ages, of every sex, it is to you only that I offer this work; nourish yourselves upon its principles: they favor your passions, and these passions, whereof coldly insipid moralists put you in fear, are naught but the means Nature employs to bring man to the ends she prescribes to him; harken only to these delicious promptings, for no voice save that of the passions can conduct you to happiness.”

“Benevolence is more a vice of pride than a true virtue of the soul.”

“I am a libertine, but I am not a criminal nor a murderer, and since I am compelled to set my apology alongside my vindication, I shall therefore say that it might well be possible that those who condemn me as unjustly as I have been might themselves be unable to offset the infamies by good works as clearly established as those I can contrast to my errors. I am a libertine, but three families residing in your area have for five years lived off my charity, and I have saved them from the farthest depths of poverty. I am a libertine, but I have saved a deserter from death, a deserter abandoned by his entire regiment and by his colonel. I am a libertine, but at Evry, with your whole family looking on, I saved a child—at the risk of my life—who was on the verge of being crushed beneath the wheels of a runaway horse-drawn cart, by snatching the child from beneath it. I am a libertine, but I have never compromised my wife’s health. Nor have I been guilty of the other kinds of libertinage so often fatal to children’s fortunes: have I ruined them by gambling or by other expenses that might have deprived them of, or even by one day foreshortened, their inheritance? Have I managed my own fortune badly, as long as I have had a say in the matter? In a word, did I in my youth herald a heart capable of the atrocities of which I today stand accused?... How therefore do you presume that, from so innocent a childhood and youth, I have suddenly arrived at the ultimate of premeditated horror? No, you do not believe it. And yet you who today tyrannize me so cruelly, you do not believe it either: your vengeance has beguiled your mind, you have proceeded blindly to tyrannize, but your heart knows mine, it judges it more fairly, and it knows full well it is innocent.”

“And you, amiable debauchees, you who since youth have known no limits but those of your desires and who have been governed by your caprices alone, study the cynical Dolmancé, proceed like him and go as far as he if you too would travel the length of those flowered ways your lechery prepares for you; in Dolmancé's academy be at last convinced it is only by exploring and enlarging the sphere of his tastes and whims, it is only by sacrificing everything to the senses' pleasure that this individual, who never asked to be cast into this universe of woe, that this poor creature who goes under the name of Man, may be able to sow a smattering of roses atop the thorny path of life.”

“...there is a sum of evil equal to the sum of good, the continuing equilibrium of the world requires that there be as many good people as wicked people...”
