With this properly understood, we can now turn to the arguments. We have already met one argument for the existence of God, in Chapter 1: Descartes’s ‘trademark’ argument. It did not seem all that strong, and in fact at a later point in his book, Meditation V, Descartes supplemented it with another. The second was a version of a much older argument, the ontological argument of St Anselm (1033–1109). Anselm defines God as a being ‘than which nothing greater can be conceived’.
