Cartesian Doubt

Definition

Cartesian doubt is a philosophical method developed by René Descartes that involves systematically questioning and doubting all beliefs and knowledge to establish a firm foundation for true understanding. This approach emphasizes skepticism as a way to strip away false beliefs and arrive at certainty, ultimately leading to the famous conclusion 'Cogito, ergo sum' ('I think, therefore I am'). This method is crucial in shaping the development of the scientific method and empiricism by promoting critical thinking and reliance on reason.
