René Descartes (March 31, 1596 - February 11, 1650), also known as "Renatus Cartesius" (latinized form), was a highly influential French philosopher, mathematician, scientist, and writer. Dubbed the "Father of Modern Philosophy", and the "Father of Modern Mathematics", much of subsequent western philosophy is a reaction to his writings, which have been closely studied from his time down to the present day.
