This paper begins with a revaluation of Carnap's critique of existence questions, and finds that with modification his argument is successful in giving a prima facie cause for doubt that the ontological question addressed by religious realists and non-realists has content. The second part of the paper argues that these doubts can be met with proper attention to the role of truth in the religious realism debate. The paper concludes by arguing for a close relationship between the semantic and the ontological varieties of religious realism.
