Best Answer

Descartes' first principle was "Cogito, ergo sum" ("I think, therefore I am"), emphasizing the certainty of self-existence through the act of doubting. His second principle was the distinction between mind (res cogitans) and body (res extensa), setting the foundation for his dualistic metaphysical framework.
