Rene Descartes
Rene Descartes was a French philosopher. Descartes had a connection to the experimental philosophy networks of the day. Rene Descartes sought to replace the Scholastic philosophical tradition altogether. Descartes questioned reality as it is interpreted through the senses. Descartes' insight was that all perceived phenomenon is attributable to the motion of an invisible sea of corpuscles. Human thought and God were excluded from this scheme, as it was thought by Descartes that these are not constituents of the physical universe. Within this philosophical framework, Descartes proposed that different kinds of motion were not fundamentally different. They would all be different manifestations of corpuscular motions obeying the principles of the universe.
What was particularly influential were his explanations of:
Circular astronomical motions are explained in terms of a vortex motion of corpuscles in space. Descartes maintained that the vacuum could not exist.
Gravity was explained by the pushing of objects downward by corpuscles.
