What is the Cartesian ego?

The Cartesian ego, originating from the philosophy of René Descartes, refers to the concept of the self as a thinking, self-aware subject. Descartes famously articulated "Cogito, ergo sum" ("I think, therefore I am"), asserting that the act of thinking is proof of one's existence. This idea emphasizes the importance of consciousness and rational thought in defining the self, distinguishing the Cartesian ego as a foundational element of modern philosophy and the study of identity.
