Philosophy in the Bedroom (La Philosophie dans le boudoir) is a 1795 erotic 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.
