Anselm and the Problem of Ostending God

Kripke raises the question concerning how the reference to God might be fixed, and Augustine makes it the leading question of the Confessions: How can I call upon God and not someone else instead? In this paper, I argue that this question is the central concern of Anselm’s Proslogion, which explicitly adopts the dialogical form of Augustine’s Confessions. Anselm does not define God but instead fixes the reference to God through an ostension or indexical description. The same linguistic formulation, “God is that than which nothing greater can be thought,” has three functions: as an ostension, it points out God as that being and not another; as a criterion for selection, it ostensibly picks out a referent that exists rather than not; finally, as a rule for analysis, it provides a principle to clarify the necessary properties of the God that has been so ostended.
