"Discourse on the Method" is a philosophical and scientific treatise written by René Descartes in 1637. In this work, Descartes outlines his approach to acquiring knowledge, emphasizing the importance of doubt and systematic reasoning. He famously states, "I think, therefore I am," highlighting the role of self-awareness in understanding existence. The text is divided into six parts, covering topics such as the nature of knowledge, the existence of God, and the distinction between mind and body. Descartes' method encourages critical thinking and serves as a foundation for modern scientific inquiry, influencing later philosophers and scientists.
