Cartesian doubt is a philosophical method associated with René Descartes, a 17th-century French philosopher, mathematician, and scientist. This method involves systematic skepticism about the validity of one’s beliefs and knowledge claims in order to establish a foundation for true knowledge. Descartes employed this technique in his work "Meditations on First Philosophy," where he sought to identify what can be known with absolute certainty.
