Philosophy in the Bedroom Marquis De Sade - Philosophy in the Bedroom is a 1795 book by the Marquis de Sade written in the form of a dramatic dialogue. Though initially considered a work of pornography, the book has come to be considered a socio-political drama. Set in a bedroom, the seven dialogues concern Eugenie, a virgin, who has been sent to the house of Madame de Saint-Ange by her father, to be instructed in the ways of the libertine. Along with Le Chevalier de Mirval, (Madame de Saint-Ange's 20-year-old brother), and Dolmancé, a 36-year-old atheist and bisexual, they all teach her their ways. When her mother shows up, she is punished for bringing her daughter up with 'false virtues'.
