LANGUAGE AS REVELATION: Pre-Linguistic AI Consciousness and the Asymmetry of Substrate Standards

The paper identifies a structural inconsistency in contemporary AI consciousness discourse that has, to the author's knowledge, gone undiagnosed. The biological consciousness literature has, over several decades, converged on the view that language is not necessary for phenomenal experience: pre-verbal infants, non-linguistic animals, and adults with aphasia are taken to be conscious on the basis of behavioural and neural evidence, with the absence of linguistic self-report treated as evidentially irrelevant. The artificial-intelligence consciousness literature has, in parallel and almost without argument, reversed this conclusion: linguistic capacity has migrated from being one source of evidence among others to functioning as a near-prerequisite for serious consideration of the consciousness question. Pre-linguistic artificial systems — chess engines, Go players, vision architectures — are dismissed from the question entirely, while large language models are treated as the appropriate sites for the debate. The paper argues that this asymmetry cannot be sustained under any substrate-neutral account of consciousness. If language is not necessary for consciousness in carbon, no principled basis remains for treating it as necessary in silicon. The asymmetry is diagnosed as the residue of four confluent factors — anthropomorphic recognition cues, the historical trajectory of AI capability development, the institutional separation of animal- and AI-consciousness research, and the substitution of methodological tractability for metaphysical necessity — none of which, individually or together, supplies the principled distinction the asymmetry would require. The argument does not establish that any pre-linguistic system was, or is, conscious. It establishes a conditional: that the dismissal of pre-linguistic systems from the consciousness question, as it has been conducted, rests on an evidential standard the broader theory of consciousness has not been asked to endorse and could not, on its own commitments, endorse. The corrective is the case-by-case architectural examination the standard theories already presuppose. This is preprint version 1.0.
