"Cartesianism is the name given to the philosophical doctrine (or school) of Ren\u00E9 Descartes. Descartes is often regarded as the first thinker to emphasize the use of reason to develop the natural sciences. For him, the philosophy was a thinking system that embodied all knowledge, and expressed it in this way:Cartesians view the mind as being wholly separate from the corporeal body."@en .
