Descartes intends to replace the “mentally” influenced phenomenon to the subordinate status of a composite effect. The most prominent advocate of a particle theory of light was Newton’s corpuscular model survived into the early years of the 19th century, at which time evidence for the wave nature of light became overwhelming. As a consequence of his first law of motion, Descartes insists that
