Homo Semanticus: Meaning-Holding as an Anthropological and Technical Threshold

This paper argues that the next decisive anthropological threshold is not a further increase in intelligence, information-processing speed, or expressive fluency, but the emergence of a new regime of semantic maturity: the capacity to hold meaning. By holding I do not mean merely possessing meanings, beliefs, symbols, or representations. I mean the temporally extended ability to generate, preserve, regulate, and transmit semantic order under conditions of pressure, ambiguity, and coupling without suffering structural collapse. The paper makes four contributions. First, it distinguishes meaning-holding from meaning-possession and defines holding as a viability condition rather than a stock concept. Second, it argues that membrane concepts drawn from autopoiesis, enactivism, active inference, and distributed cognition provide a better unit of analysis than either the isolated subject or the purely disembodied sign. Third, it integrates this boundary-centered view with a scope-disciplined formal proposal from the current Semantic Physics programme: if a substrate admits a local, first-order, dissipative, non-chiral, productive closure of type T1-T5, then its local admissible transport state is canonically parameterized by four irreducible sectors, Q = (D, h, B, ), namely a driving field, holding capacity, internal blockade, and boundary semipermeability. The strongest universal claim is therefore conditional, not absolute: cross-substrate scope remains an empirical question. Fourth, it recasts Homo semanticus not as a biologically new species but as a regulative anthropological figure for the twenty-first century: the human being capable of selective openness, non-collapsing integration, non-depleting transmission, and tension-bearing continuity. The paper closes by outlining a falsifiable research programme for meaning-holding across persons, institutions, and machines, with open-weight language models, finance, and membrane-rich biological systems treated as privileged witness families.
