The other chief collaborators were Pechmeja, Holbach, Paulze, the farmergeneral of taxes, the Abbe Martin, and Alexandre Deleyre.
PAUL HEINRICH DIETRICH HOLBACH, BARON D' (1723-1789), French philosopher and man of letters, of German origin, was born at Heildeisheim in the palatinate in 1723.
Denying the existence of a deity, and refusing to admit as evidence all a priori arguments, Holbach saw in the universe nothing save matter in spontaneous movement.
Holbach exposed the logical consequences of the theories of the Encyclopaedists.
In the Systeme social (1 773), the Politique naturelle (1773-1774) and the Morale universelle (1776) Holbach attempts to rear a system of morality in place of the one he had so fiercely attacked, but these later writings had not a tithe of the popularity and influence of his earlier work.
