Pierre Gassendi (1592–1655) and Walter Charlton (1619–1707) influenced Boyle. In 1656 Charlton brought Gassendi’s ideas about atoms to England with his Physiologia Epicuro-Gassendo-Chartonia; or, a Fabrick of Science Natural, upon the Hyopthesis of Atoms, Founded by Epicurus, Repaired by Petrus Gassendus, Augmented by Walter Charlton (1654). Charleton revised Gassendi’s view that everything, including the soul, was made up of material atoms. This view entailed that the soul was a physical thing, which was against the beliefs of most theologians and members of the clergy.
