Abstract
Anselm's argument has two distinct conclusions: (a) we cannot intelligibly doubt that god exists, and (b) this god, whose existence we cannot doubt, exists necessarily. if we replace anselm's vague conception of god by the spinozistic conception of substance, a defensible version of the ontological argument, understood as having these two conclusions, can be constructed. two important consequences of this analysis are: (1) the ontological argument, properly understood, deals simply with the concept of substance. it is a further question whether substance ought to be understood as god. (2) the ontological argument does not actually demonstrate the existence of anything. it simply makes clear the consequences of adopting a metaphysical view which employs the spinozistic conception of substance
