CHAPTER ONE A "COPERNICAN REVOLUTION" IN THEOLOGICAL METHOD A. Introduct1on The subject of theology is the history of the communion of God with man and of ...

It has become somewhat ontologically fashionable for theists to embrace anti-realist views of abstract objects. On pain of consistency, however, I will argue that any theist who accepts the S5 ontological argument for the existence of God should also accept a parallel S5 ontological argument for the existence of abstract objects. This is because the same ontological and modal inferences thought to demonstrate the existence of God can also be used to demonstrate the existence of numbers. I further argue that being ontologically consistent here might come at the price of being theologically unacceptable, as the argument for numbers would seem to vindicate a platonistic view of abstracta—but platonism is incompatible with the traditional concept of God. I conclude by suggesting what I see as the only way out of this dilemma, which is to embrace a view akin Augustine’s where abstracta exist “nowhere but in the very mind of the Creator.” Something like the Augustinian view of abstracta, therefore, can be seen as an indirect theological consequence of the S5 ontological argument for the existence of God.

The ontological argument is one of the most intriguing lines of reasoning in Western thought. Leaving behind debates over the proper relation between science and religion, it makes a simple move from conceptual analysis to existence in order to prove the existence of god. The ontological argument will be reviewed against the background of the contemporary debate on thought experiments. Assuming that the ontological argument fails as a philosophical proof, I will argue that its move from concept to existence might best be understood as a thought experiment of revealed theology (a theology based on revelation – unlike philosophical theology/natural theology). Viewed from this perspective it makes sense that Anselm of Canterbury offered his versions of the ontological argument in the form of a prayer, which, presupposing the existence of god, seems to run counter to a proof of god's existence.
