René Descartes - Meditation #3 - A Cosmological Proof of God’s Existence

This video lecture is about Rene Descartes’ third Meditation on First Philosophy. It is part of an introduction to philosophy course. In this meditation Descartes offers a cosmological proof of the existence of god. The attempted proof starts from the fact that Descartes has the idea of an all perfect being.
