a1 Department of Philosophy, Oklahoma State University, 308 Hanner Hall, Stillwater, OK 74078–5064


Just prior to The Critique of Pure Reason's examination of the various arguments for God's existence, Kant discusses the conceptual relationship between the idea of an ens realissimum and that of a necessary being. The purpose of this paper is to illustrate the extent to which this discussion informs his claim that the cosmological argument depends upon the ontological argument.
