The Abstraction Fallacy in Light of Dual-Closure: A Response to Lerchner (2026)

Alexander Lerchner's "The Abstraction Fallacy: Why AI Can Simulate But Not Instantiate Consciousness" (2026) offers a compelling critique of computational functionalism by arguing that computation is a mapmaker-dependent description rather than an intrinsic physical process. This paper does not dispute Lerchner's conclusions but demonstrates that his central insights find a deeper metaphysical grounding within the Dual-Closure Framework developed in the author's prior work (2025–2026). It is argued that Lerchner's notion of the "mapmaker" can be more fully understood when interpreted in light of two conditions identified by the Dual-Closure Law of Authentic Feeling: existential vulnerability and non-duplicability. While Lerchner's argument can be formulated independently, the Dual-Closure Framework provides a broader metaphysical account within which the Abstraction Fallacy can be more deeply explained and extended. This integration also allows the implications of Lerchner's critique to be developed beyond the philosophy of mind into questions of normativity, jurisprudence, and artificial intelligence alignment.
