The primary and most beautiful of nature's qualities is motion

I've been to Hell. You've only read about it.

Your body is the church where Nature asks to be reverenced.

It has, moreover, been proven that horror, nastiness, and the frightful are what give pleasure when one fornicates. Beauty is a simple thing; ugliness is the exceptional thing. And fiery imaginations, no doubt, always prefer the extraordinary thing to the simple thing.

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.

Hope is the most sensitive part of a poor wretch's soul; whoever raises it only to torment him is behaving like the executioners in Hell who, they say, incessantly renew old wounds and concentrate their attention on that area of it that is already lacerated.

One must do violence to the object of one's desire; when it surrenders, the pleasure is greater.
