The Illusion of Descartes

Some people claim that reality is an illusion, and that we can never really “know” anything because our thinking is nothing more than a biological process. Rene Descartes was a French philosopher who famously made the claim, “I think, therefore I am.” In this lesson, Dr. R.C. Sproul explains how Descartes’ logic can help us defend the reality of our own existence and lays a foundation for Christian truth.
