In libertinage, nothing is frightful, because everything libertinage suggests is also a natural inspiration; the most extraordinary, the most bizarre acts, those which most arrantly seem to conflict with every law, every human institution... even those that are not frightful, and there is not one amongst them all that cannot be demonstrated within the boundaries of nature.

Never lose sight of the fact that all human felicity lies in man's imagination, and that he cannot think to attain it unless he heeds all his caprices. The most fortunate of persons is he who has the most means to satisfy his vagaries.

Between understanding and faith immediate connections must subsist.

The imagination is the spur of delights... all depends upon it, it is the mainspring of everything; now, is it not by means of the imagination one knows joy? Is it not of the imagination that the sharpest pleasures arise?

Behold, my love, behold all that I simultaneously do: scandal, seduction, bad example, incest, adultery, sodomy! Oh, Satan! one and unique God of my soul, inspire thou in me something yet more, present further perversions to my smoking heart, and then shalt thou see how I shall plunge myself into them all!

The most fortunate of persons is he who has the most means to satisfy his vagaries.

Do not breed. Nothing gives less pleasure than childbearing. Pregnancies are damaging to health, spoil the figure, wither the charms, and it's the cloud of uncertainty forever hanging over these events that darkens a husband's mood.
