What does one want when one is engaged in the sexual act? That everything around you give you its utter attention, think only of you, care only for you...every man wants to be a tyrant when he fornicates.

If it is the dirty element that gives pleasure to the act of lust, then the dirtier it is, the more pleasurable it is bound to be.

Nature, who for the perfect maintenance of the laws of her general equilibrium, has sometimes need of vices and sometimes of virtues, inspires now this impulse, now that one, in accordance with what she requires.

I am about to put foward some major ideas; they will be heard and pondered. If not all of them please, surely a few will; in some sort, then, I shall have contributed to the progress of our age, and shall be content.

Certain souls seem hard because they are capable of strong feelings, and they sometimes go to rather extreme lengths; their apparent unconcern and cruelty are but ways, known only to themselves, of feeling more strongly than others.

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

Nature has not got two voices, you know, one of them condemning all day what the other commands.
