In The Marquis d’Argens: A Philosophical Life Julia Gasper analyzes the life and works of an influential Enlightenment writer and philosopher. The facts of d’Argens’ life as well as his works have been a source of controversy due to the many rumors and anonymous publications erroneously linked to him. Through meticulous research, Gasper provides the only comprehensive list of d’Argens’ works and separates the realities of his life from the myths that have built up around him. Accused of being a libertine or an unoriginal mimic of greater minds, d’Argens has too often been dismissed as an unimportant figure. Gasper defends this much maligned philosopher and reveals how imaginative and influential he truly was.
