Beyond the Posthuman: Knowledge Ecology and the Relational Human in the Age of AI

The dominant posthuman narrative frames the human as something to be transcended, enhanced, or decentred as artificial intelligence advances. This paper argues that such anxiety is largely an artifact of a flawed starting point: the substantialist, Cartesian, individualist conception of the human inherited from Western modernity. Drawing on Japanese philosophy and biosemiotics, it proposes an alternative ontology in which the human is relational from the outset, and in which co-evolution, resilience, and conscious society can be reconceived as processes of shared meaning-creation.

Nishida Kitarō’s logic of place (basho) and Watsuji Tetsurō’s notion of ningen — the human as “betweenness” (aidagara) — show that the self is not a bounded substance but a node in a field of relations. Knowledge, on this view, is not information possessed by individuals but is generated in Ba, the shared context-in-motion underlying the SECI model of knowledge creation developed with Ikujiro Nonaka. The paper extends this into a framework of Knowledge Ecology: organizations and societies understood as living, semiotic systems in which meaning circulates and evolves.

Two pillars support the argument. First, Imanishi Kinji’s theory of habitat segregation (sumiwake) offers a distinctively Japanese, non-Darwinian account of co-evolution as symbiosis rather than competitive optimization — a resource largely absent from Western posthuman discourse and directly relevant to human–technology–nature relations. Second, biosemiotics (von Uexküll’s Umwelt, and contemporary work by Kalevi Kull and others) recasts life itself as meaning-making, bridging biological, cognitive, and cultural orders of semiosis.

From this synthesis, the human–AI relationship is reframed. AI participates in knowledge creation, but the irreducibly human contributions are tacit knowing, phronesis (practical wisdom), and kōsō-ryoku — the imaginative, conceptualizing capacity theorized by Miki Kiyoshi. Resilience, accordingly, is not mere systemic robustness but a society’s capacity to keep generating meaning under disruption. A “conscious society” is one that cultivates this capacity deliberately, through institutions and shared places that sustain collective wisdom.

The paper closes on a normative claim: in the posthuman age, meaning is a choice. What distinguishes human flourishing is not computation but the ongoing, value-laden act of choosing what matters. The transformation of the human is therefore not a movement beyond the human, but a recovery of the relational, meaning-creating being we have always been — now in conscious partnership with intelligent machines and the wider web of life. The argument draws on the author’s forthcoming monograph Knowledge Ecology: Understanding Innovation in the Age of AI (Springer), and on three decades of theory and practice in knowledge creation and innovation management.
