: operational epistemology as an evolutionary adaptationThe sensory order

Purpose – Recent findings in neurobiology, cognitive psychology, and brain evolution are interpreted in light of Hayek's construction of the sensory order as a spontaneously emergent evolutionary adaptation. The sensory order is an experimental view of reality ordered by experience. Approach – Natural selection of behavioral and cognitive adaptations is shown to result in structural change within the brain. Individual brains grow, and species brains evolve, through the construction and evaluation of hypothetical classification schemata. This process both results in the construction of the sensory order, as well as results from the particular models of objective reality that individuals have constructed, their evaluation of these models, and the comparison of our own models with those of others. Findings – Cognitive adaptations, such as belief in agency, causal reasoning, and theory of mind, are inherited because they enhance survival and reproductive opportunities. In addition, behavioral adaptations including empathy, reciprocity, social hierarchy, and peacemaking are also inherited. Socialization in larger groups required the evolution of enhanced brain connectivity permitting a greater degree and sophistication of social intercourse. Research Implications – Recent findings in neurobiology can be better related to one another in terms of how they contribute to the sensory order. Literary Darwinism, a school of literary theory, can also be understood more fully. Originality/Value of Paper – Varied developments in modern neurobiology and cognitive psychology are shown to lead to spontaneously emergent institutional structures, such as behavioral regularities and rules of morality, which further enhance the survival benefits of inherited brain structure and the sensory order.
