I have supported my deviations with reasons; I did not stop at mere doubt; I have vanquished, I have uprooted, I have destroyed everything in my heart that might have interfered with my pleasure.

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

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

Don't have children: they deform women's bodies and turn into an enemy 20 years later.

Wolves which batten upon lambs, lambs consumed by wolves, the strong who immolate the weak, the weak victims of the strong: there you have Nature, there you have her intentions, there you have her scheme: a perpetual action and reaction, a host of vices, a host of virtues, in one word, a perfect equilibrium resulting from the equality of good and evil on earth.

The primary and most beautiful of Nature's qualities is motion, which agitates her at all times, but this motion is simply a perpetual consequence of crimes, she conserves it by means of crimes only.

Lust is to the other passions what the nervous fluid is to life; it supports them all, lends strength to them all ambition, cruelty, avarice, revenge, are all founded on lust.
