Philosophical Perspectives on Human Existence: Descartes to Post-Structuralism
Rene Descartes
Descartes posits that fundamental existence stems from the thinking, self-aware subject (res cogitans). His method, methodical doubt, leads to the indubitable conclusion: “I think, therefore I am” (Cogito, ergo sum). This opens the philosophy of the subject and philosophical modernity.
