The Primordial Mind: An Integrated Neuroevolutionary Ontology of Human Psychic Architecture

The Ontology of the Primordial Mind proposed in this work presents a hierarchical,
neuroevolutionarily informed model designed to integrate findings from evolutionary psychology,
social neuroscience, Paleolithic anthropology, stress epigenetics, philosophy of emotions, and
cultural learning theory. In its current formulation, the model conceptualizes the Primordial Mind as
a psychic architecture shaped over hundreds of thousands of years, articulating basal
neurophysiological processes, socially relevant functional mechanisms, instinctive motivational
modules, pre-reflective affective filters, and a symbolic-reflexive layer that, although evolutionarily
recent, remains deeply modulated by ancestral substrates. The ontology is structured across six
interdependent levels (0 to 5), unified by transversal mechanisms that provide system-wide
plasticity, including interoception, cumulative cultural learning, active inference, HPA-axis
regulation, and environmentally responsive epigenetic processes.
Level 0 corresponds to the pre-tribal ecological and social context, characterized by small-scale
bands, high interdependence, environmental vulnerability, and elementary forms of care, vigilance,
and aggression regulation. Archaeological and ethnographic evidence suggests that these
conditions served as the ecological backdrop against which early human social tendencies were
calibrated. Level 1 represents the primordial neurophysiological infrastructure—threat detection
systems, salience networks, interoceptive circuits, and affiliative neural pathways—providing the
parameters that guide attention allocation and internal state regulation.
Level 2 encompasses the functional mechanisms that operate upon this infrastructure, such as
vigilance, bonding, status evaluation, reciprocity, fast social reading, and coalition propensity. Level
3 comprises the instinctive motivational modules—care, defensive and offensive aggression,
mate-seeking, group protection, and exploration—conceptualized not as rigid instincts but as
flexible motivational heuristics shaped by bodily states, social context, and learning history. Level 4,
the primordial affective triage, represents the convergence point between body and environment,
synthesizing interoceptive signals, implicit memories, anticipations, and social cues into rapid
emotional priorities that precede reflective cognition. Level 5, the modern reflexive mind, emerges
upon this platform, producing autobiographical narrative, symbolism, normative morality, long-term
planning, and identity—crucially without replacing earlier layers but reinterpreting and modulating
them.
The model is unified by transversal mechanisms that regulate developmental and intergenerational
calibration: interoception as the body–brain axis governing emotional valence; cumulative cultural
learning as an amplifier of ancestrally shaped competencies; epigenetic processes shaped by early
care as modulators of physiological reactivity and social sensitivity; and active inference as the
computational framework guiding uncertainty minimization in social environments.
As a conceptual framework, the proposed ontology integrates archaeological, neurobiological,
behavioral, cultural, and philosophical evidence into a coherent model of the human psyche. It
generates testable predictions—for example, that interoceptive interventions alter rapid social
choices; that synchronized rituals reduce social uncertainty and increase cooperation; that early
caregiving history shapes threat sensitivity through epigenetic pathways; and that cultural prestige
dynamics reorganize the expression of ancestral motivational modules within a few generations.
The model also reframes contemporary psychological suffering as a product of misalignments
between ancestral parameters and modern environments.
Ultimately, the Ontology of the Primordial Mind does not present itself as a final answer but as an
integrative heuristic intended to guide future research in social neuroscience, developmental
psychology, evolutionary anthropology, behavioral epigenetics, and philosophy of mind. Its strength
lies not in offering definitive conclusions but in its capacity to unify dispersed evidence, propose
plausible mechanisms, and generate productive research programs that bridge biology, culture,
and subjectivity into a coherent account of the human psyche.
