Which book was written by an atheist salon owner and explicitly denies the existence of God?
Baron d'Holbach:  He was born Paul Heinrich Dietrich in Edesheim, near Landau in the Rhenish Palatinate, but lived and worked mainly in Paris, where he kept a "salon". The System of Nature:  Most notoriously, the work explicitly denies the existence of God, arguing that belief in a higher being is the product of fear, lack of understanding, and anthropomorphism.
