Would this be a bridge between presuppositional and classical apologists? I am very unfamiliar with the presuppositional method, and am not sure of whether the disagreement lies with the workability of the ontological and cosmological arguments, or the appropriateness of using them in defense of the faith. But it seems there could be a harmonizing of the two positions, given that the 'God' arguments do not go far enough in proving God apart from oneself. That ultimately, philosophical speaking, there would remain a choice between theism and solipsism. Not that it is much of a choice.
