by Marquis de Sade

Philosophy in the Bedroom is a 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 two lead characters make the argument that the only moral system that reinforces the recent political revolution is libertinism, and that if the people of France fail to adopt the libertine philosophy, France will be destined to return to a monarchic state.
