Over at UrbanPhilosophy.net is a Philosophy of Religion student from the University of Toronto, Mitchell LeBlanc, who has been endeavouring to make a case against presuppositional apologetics. Coursing a new direction from his original first three drafts, [1] perhaps due to the daunting scope of such a task or perhaps due to the criticisms from Chris Bolt and others at ChoosingHats.com, [2] the final draft version of the article [3] targets the Transcendental Argument for God (TAG) as argued for by the late philosopher Greg L. Bahnsen from Covenant Media Foundation.
As did his mentor Cornelius Van Til, Bahnsen defended the transcendental argument as singularly the only cogent and self-consistent Christian apologetic method by virtue of being uniquely grounded upon the distinctive presuppositions of revelational epistemology. [4] Van Til’s extensive work is considered by some to be a contribution to Christian philosophy of Copernican dimensions, [5] wherein he demonstrated by indirect proof the existence of God as the necessary precondition for the intelligibility of reality and the human experience thereof, such that God, as affirmed by Christian orthodoxy, is not a conclusion drawn from rational argument (evidentialism) but is logically prior to any reasoning at all (presuppositionalism). [6] As Van Til framed the matter in his An Introduction to Systematic Theology, “Unless God exists as ultimate [and] self-subsistent, we could not even know anything; we could not even reason that God must exist, nor could we even ask a question about God.” [7]
LeBlanc at this point holds a considered view that the TAG is not merely debatable but in fact false, taking as his point of evaluation the fundamental laws of logic, concluding that they “cannot depend on the Christian God” and therefore the TAG “is not sound”—and must remain so “pending further defense” thereof. His bold conclusion notwithstanding, we may inquire with skepticism whether or not LeBlanc really has successfully defeated the TAG as it already stands, never mind its further defense.
