Sapience as Autonomy Beyond Mere Biological Agency

A persistent failure in naturalistic accounts of mind is the silent downgrading of the explanandum. When cognitive science reduces sapience to computation, or evolutionary psychology treats rational agency as an adaptive heuristic, the explanatory gain is purchased by substituting a simpler target for the original one. What gets explained is no longer the capacity that generates normative, necessary knowledge — the kind of knowledge science actually claims to produce — but something behaviorally adjacent and philosophically deflated.

Piaget and Peirce both diagnosed this problem and responded by setting the threshold for sapience unusually high. For both thinkers, the distinctively human capacity is not mere sentience, teleological behavior, or even instrumental agency. It is autonomy in the Kantian sense: agency governed by self-legislated norms, which is inherently reflective, intersubjective, and semiotic. This is the capacity that makes science a normative practice rather than a mere behavioral regularity — one in which knowledge is not just produced but obligated to be a certain way because reality has a certain structure.

The unresolved challenge is to construct an integrative evolutionary framework that runs continuously from the physical through the biological to the cultural without collapsing the qualitative distinctiveness of the sapient at the upper end. Piaget's genetic structuralism and Peirce's semiotics were serious attempts at exactly this synthesis. Their failure to fully close the gap is not a reason to abandon the ambition but a measure of how genuinely hard the problem is. reductive transhumanism fills the vacuum left by that failure, and its conclusions follow logically — but only from premises that have already smuggled in the downgrade.
