Now I beg of you to tell me whether I must love a human being simply because he exists or resembles me and whether for those reasons alone I must suddenly prefer him to myself?

Let us give ourselves indiscriminately to everything our passions suggest, and we will always be happy...Conscience is not the voice of Nature but only the voice of prejudice.

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

No lover, if he be of good faith, and sincere, will deny he would prefer to see his mistress dead than unfaithful.

Sex without pain is like food without taste

Lust's passion will be served; it demands, it militates, it tyrannizes.

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.
