The Cartesian Method of Doubt is a philosophical approach developed by René Descartes that involves systematically questioning and doubting all beliefs to establish a firm foundation for knowledge. This method is central to Descartes' quest for certainty, where he suspends judgment on anything that can be doubted, ultimately leading to the famous conclusion, 'Cogito, ergo sum' (I think, therefore I am). This method is significant in the context of modern philosophy as it shifts the focus from external authorities to individual reasoning and skepticism.
