The Ontological Argument (Part 3): Descartes v Kant

Picture of a wallet with cash in itLearning aims: This lesson explores René Descartes version of the Ontological Argument, and the critiques of Immanuel Kant with regard to this. Descartes version of the Ontological Argument centers on the notion of existence, and in particular why this is something we cannot take away from God. The lesson begins with a recap of Anselm's version of the argument, and shows how Descartes version differs from him on this point. The lesson also considers in some depth the triangle analogy, and sets this within the context of two 'proofs' for God’s existence as discussed by Descartes in the Third Meditation. The second part of this lesson explores Immanuel Kant's critiques of Descartes understanding of the notion 'existence'. After briefly considering Kant's distinction between analytic and synthetic statements, the lesson explains why Kant believed existence could never function as a predicate in a statement, and also why it makes no logical sense to talk of God having existence.
