Can a transcendental argument reach the world, or only our beliefs?
The strongest version of the argument we could find still has a gap we have not closed.
Does a transcendental or TAG-style argument establish mind-independent worldly X, or only belief/appearance that X?
Thought/knowledge presupposition → mind-independent worldly ground?
Argument incompleteStrongest case · A world-directed transcendental argument needs □(T → X), not merely □(T → B(X)). Proponents propose revelational epistemology and divine-mind grounding as the stronger conditional; rivals press Stroud’s substitution (belief-only) countermodel.
What it still does not settle · No checked packet independently establishes the stronger conditional for the Orthodox-Christian ground without assuming the revelation/metaphysics in dispute.
Can Sher-style formal/structural realism undercut TAG’s only-mind exclusion?
Argument incompleteStrongest case · Sher supplies an explicit formal-structural account of logical laws with truth-based normativity claims; TAG must show why that terminus fails under the same rubric rather than label it impersonal by fiat.
What it still does not settle · Normativity and reliable access bridges remain OPEN on both sides after source-symmetric testing.
