Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences

Descartes's seminal "Discourse on the Method" laid the groundwork for modern Western philosophy and science. In this revolutionary work, he systematically doubts all received knowledge to arrive at fundamental truths, famously declaring "I think, therefore I am." It remains an essential text for understanding the origins of rationalism and its profound impact on scientific inquiry and human thought.
