Maternal Care as the First Inversion of Self-Centered Relevance

The argument traces a pivotal transition in the evolution of selfhood: the moment when Relevance realization — the process by which an agent organizes its world according to adaptive significance — undergoes a vectorial inversion through mammalian maternity. Prior to this transition, Relevance realization is fundamentally centripetal: the organism evaluates how environmental features bear on its own needs. With maternity, the vector reverses. The mother's Relevance realization becomes centrifugal, organized around the question of how she is relevant to a dependent other whose needs she must model as genuinely distinct from her own.

This is not merely an extension of existing care behaviors but a structural novelty in the Relevance realization machinery itself. The affective dimensions already embedded in recursive Relevance realization — arousal, motivation, emotional salience — are now directed outward through the construction of a model of another being's states. The mother must simultaneously differentiate her own needs from the offspring's, track the offspring's condition relative to competing demands, and sustain this at significant bioenergetic cost. The evolutionary pressure here is immense and the cognitive demands are qualitatively new.

What emerges from this inversion is a richer architecture of self-modeling. The self is now constituted relationally, within a dyadic unit that is neither simple self-extension nor fully independent otherness. The offspring is a projected self that is nevertheless genuinely different. This dyadic structure — intimate mutual modeling between two beings whose relevance landscapes partially overlap but do not coincide — creates the developmental and evolutionary platform for attachment, social cognition, and ultimately the full architecture of human personhood.
