All, all is theft, all is unceasing and rigorous competition in nature; the desire to make off with the substance of others is the foremost - the most legitimate - passion nature has bred into us and, without doubt, the most agreeable one.

— Marquis de Sade

...and above all, you should not think of writing as a way of earning your living. If you do, your work will smell of your poverty. It will be colored by your weakness and be as thin as your hunger. There are other trades which you can take up: make boots, not books.

— Marquis de Sade

Anything beyond the limits and grasp of the human mind is either illusion or futility; and because your god having to be one or the other of the two, in the first instance I should be mad to believe in him, and in the second a fool.

— Marquis de Sade

Are your convictions so fragile that mine cannot stand in opposition to them? Is your God so illusory that the presence of my Devil reveals his insufficiency?

— Marquis de Sade

Beauty belongs to the sphere of the simple, the ordinary, whilst ugliness is something extraordinary, and there is no question but that every ardent imagination prefers in lubricity, the extraordinary to the commonplace

— Marquis de Sade

Believe me, Eugenie, the words "vice" and "virtue" supply us only with local meanings. There is no action, however bizarre you may picture it, that is truly criminal; or one that can really be called virtuous. Everything depends on our customs and on the climates we live in. What is considered a crime here is often a virtue a few hundred leagues away; and the virtues of another hemisphere might, quite conversely, be regarded as crimes among us. There is no atrocity that hasn't been deified, no virtue that hasn't been stigmatized.

— Marquis de Sade

Between understanding and faith immediate connections must subsist.

But to declare his wishes only in some unknown corner of Asia, to choose the most double-dealing and the most superstitious of peoples as followers, and the vilest, most ridiculous, and most roguish working man as representative, to muddle up the message so much that it is impossible to comprehend, to teach it only to a tiny number of individuals while leaving everyone else in the dark, and to punish them for remaining there... Oh, no, Therese, no, no, such atrocities cannot be our guide. I would rather die a thousand times than believe in them. When atheism wants martyrs, let it choose them and my blood is ready.

— Marquis de Sade

Chimerical and empty being, your name alone has caused more blood to flow on the face of the earth than any political war ever will. Return to the nothingness from which the mad hope and ridiculous fright of men dared call you forth to their misfortune. You only appeared as a torment for the human race. What crimes would have been spared the world, if they had choked the first imbecile who thought of speaking of you.

— Marquis de Sade

Conversation, like certain portions of the anatomy, always runs more smoothly when lubricated.
