 On Hartshorne’s view, metaphysics does not deal with realities beyond the physical, but rather with those features of reality that are ubiquitous or that would exist in any possible world. And he does not think that it is possible to think of a preeminent being that existed only contingently since if it did exist contingently rather than necessarily, it would not be preeminent. That is, God’s existence is either impossible (positivism) or possible, and, if possible, then necessary (theism). He is assuming here that there are three alternatives for us to consider: (1) God is impossible; (2) God is possible, but may or may not exist; (3) God exists necessarily. The ontological argument shows that the second alternative makes no sense. Hence, he thinks that the prime task for the philosophical theist is to show that God is not impossible.
