René Descartes (born March 31, 1596—died February 11, 1650) (Vanessa Gibson)
According to the Stanford
Encyclopedia of Philosophy, Descartes was "a creative mathematician of the
first order, an important scientific thinker, and an original
metaphysician." Those being listed in chronological order. Although
surrounded by Aristotelian frameworks in his fields, Descartes was a skeptic—one
who was not afraid to desert tradition. In fact, it was his life's mission
"to reform all knowledge," (Hatfield).
Mathematics was Descartes first passion
and perhaps his greatest interest. As a mathematician, he developed equations
and systems such as the Cartesian coordinates, which, among other
contributions, would later evolve into analytic geometry. In the "natural
philosophy," or science department, he is credited with several large
achievements that would push forward modern science, some of such achievements
were his studies of the universe, the components of matter, and how light is
reflected and refracted. In metaphysics, which, for Descartes, was not entirely
separate from physics, his most notable and long-lasting theory was what we
today call "mind-body dualism," but in the 17th century, for
Descartes, it was more of a distinction. He claimed that "the nature of
the mind (a thinking, non-extended thing) is completely different from that of
the body (an extended, non-thinking thing), and therefore it is possible for
one to exist without the other." He did not mean that they do exist
without the other, only that they could, because they are separate and
completely different substances (Skirry, "Mind-Body"). Related to
this, is Descartes extremely well-known reasoning—originally written in French
as "Je pense, donc je suis," and most famous for its Latin phrasing
"Cogito, ergo sum." We know it in English as "I think, therefore
I am;" and that because we can say that "I exist," it is an absolute
certainty that we do exist.
