Definition from Wiktionary, the free dictionary
- (philosophy) Ideology that discusses reality and change in terms of particles (corpuscles) and their motion.
- The main difference between atomism and corpuscularism was the existence of the void. For Descartes, there could be no vacuum, and all matter was constantly swirling to prevent a void as corpuscles moved through other matter. Another key distinction between Descartes' corpuscularism and classical atomism is Descartes' concept of mind/body duality, which allowed for an independent realm of existence for thought, soul, and most importantly, God.
