The Cartesian Mind is the Basis of Knowledge: An Analytical Study

Abstract

  The concept of reason according to the philosopher Rene Descartes revolves around the idea that reason is the basic essence that distinguishes man, and reason is the primary source of knowledge and certainty, and it is the tool that enables man to think and contemplate, and distinguish between right and wrong. In Descartes' philosophy, reason is defined as an essence, a thought, which distinguishes human beings from other creatures, and reason is capable of doubt, questioning and thinking in an abstract way, and these abilities are what enable man to reach truths and certain knowledge. Reason is the basis for achieving certainty, which appeared in his skeptical approach known as the cogito or his famous saying "I think, therefore I am". This phrase represents his first and basic certainty that he reached through doubting everything except the existence of reason itself as a thinking thing.
