“Crime is to the passions what nervous fluid is to life: it sustains them, it supplies their strength.”

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

“Variety, multiplicity are the two most powerful vehicles of lust.”

“You say that my way of thinking cannot be tolerated? What of it? The man who alters his way of thinking to suit othere is a fool. My way of thinking is the result of my reflections. It is part of my inner being,the way I am made. I do not contradict them, and would not even if I wished to. For my system, which you disapprove of is also my greatest comfort in life, the source of all my happiness -it means more to me than my life itself.”
