BEYOND TRANSHUMANIST PERFECTION: A Prohumanist Philosophical Anthropology for AI, Digital Health, and Dignified Longevity in the Transmodern Condition

AI-enabled medicine and digital health increasingly instantiate an implicit philosophical anthropology: the person is treated as an improvable system whose deviations from an ideal baseline can be detected, predicted, and corrected through continuous data capture and algorithmic mediation. In this framing, health is reinterpreted as optimisation and longevity becomes a technical horizon of open-ended extension. This article argues that the decisive conflict is not between being for or against enhancement, but between two rival conceptions of enhancement grounded in divergent valuations of embodiment and divergent political grammars of governance. Building on recent clarifications that separate human enhancement from transhumanism, the paper develops a prohumanist philosophical anthropology oriented to dignified longevity: bounded improvement accountable to dignity, vulnerability, justice, and meaning, rather than perfection as an end-state. The transmodern condition—platformised infrastructures, behavioural nudging, and asymmetries of expertise—intensifies the risk that optimisation becomes the default norm in health governance. Against this backdrop, the article proposes four prohumanist constraints for AI-mediated health systems: proportionality, contestability, non-totalisation, and epistemic autonomy. These constraints are translated into design and regulatory criteria for high-stakes health settings, yielding a set of evaluative questions intended to discipline enhancement claims and to protect agency and dignity under conditions of pervasive digital mediation.
