Rene descartes is a famous French philosopher. Turan Hella (now renamed Descartes to commemorate this great man) was born in the Antilles-Loire province of France and died in Stockholm, Sweden.

Descartes is a famous French philosopher, physicist, mathematician and theologian. He made an important contribution to the development of modern mathematics, because he formulated the geometric coordinate system and was known as the father of analytic geometry. Together with the British philosopher Francis Bacon, he initiated the "epistemological" turn of modern western philosophy.

Descartes, the representative of dualism, left a famous saying "I think, therefore I am" (or translated as "thinking is the only definite existence") and put forward the idea of "universal doubt". Descartes was one of the founders of modern European philosophy, and Hegel called him "the father of modern philosophy".
