Discourse on the Method is a philosophical and methodological treatise by Renรฉ Descartes published in 1637, which outlines his approach to scientific inquiry and establishes a foundation for modern philosophy. It emphasizes reason as the primary source of knowledge, advocating for systematic doubt and the use of mathematical principles in understanding the natural world. This work connects to Cartesian philosophy, where Descartes argues for a mechanistic view of nature, suggesting that the universe operates like a machine governed by physical laws.
