Les liaisons dangereuses

Marquise de Merteuil: When I came out into society, I was fifteen. I already knew that the role I was condemned to, namely to keep quiet and do what I was told, gave me the perfect opportunity to listen and observe. Not to what people told me, which naturally was of no interest, but to whatever it was they were trying to hide. I practiced detachment. I learned how to look cheerful while, under the table, I stuck a fork into the back of my hand. I became a virtuoso of deceit. It wasn't pleasure I was after, it was knowledge. I consulted the strictest moralists to learn how to appear, philosophers to find out what to think, and novelists to see what I could get away with. And in the end, I distilled everything to one wonderfully simple principle: win or die.
