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?

Sexual pleasure is, I agree, a passion to which all others are subordinate but in which they all unite.

At all times, in every century, every age, there has been such a connection between despotism and religion that it is infinitely apparent and demonstrated a thousand times over, that in destroying one, the other must be undermined, for the simple reason that the first will always put the law into the service of the second.

There is no more lively sensation than that of pain; its impressions are certain and dependable, they never deceive as may those of the pleasure women perpetually feign and almost never experience.

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.

My passions, concentrated on a single point, resemble the rays of a sun assembled by a magnifying glass: they immediately set fire to whatever object they find in their way.

Murder is a horror, but an often necessary horror, never criminal, which it is essential to tolerate in a republican State. Is it or is it not a crime? If it is not, why make laws for its punishment? And if it is, by what barbarous logic do you, to punish it, duplicate it by another crime?
