The structuring and transformation of myth is presented as a function of a number of brain “operators.” Each operator is understood to represent specifically evolved neural tissue primarily of the neocortex of the brain. Mythmaking as well as other cognitive processes is seen as a behavior arising from the evolution and integration of certain parts of the brain. Human ceremonial ritual is likewise understood as the culmination of a long phylogenetic evolutionary process, and a neural model is presented to explain its properties. Finally, the mechanism by which ritual is used to resolve the antinomies of myth structure is explored.

This paper first considers the current confusion in categorizing and even describing mystical states, including experiences of God, the Void, and lesser religious experiences. The paper presents the necessity of studying the neuropsychological substrate of such experiences both to understand them in greater depth and to help resolve scholarly confusion in this area. As a prelude to presenting a neuropsychological model, the basic principles of brain organization are reviewed, including hemispheri-city; primary, secondary, and tertiary sensory receptive areas; their motor analogues; prefrontosensorial polarity; and the integration of limbic functioning into cortical activity. A neuropsychological model for mystical states is then presented in terms of differential stimulation and deafferentation of various tertiary sensory association areas, along with integration of various patterns of limbic stimulation.

The phenomenology of certain mystical states is contrasted with the sense of “baseline” reality in an exploration of primary senses of reality. Nine theoretical and eight actual primary senses of reality are described. A neurophysiological model is presented to account for these states, and their possible adaptive significance is considered from an evolutionary perspective. Finally the state of absolute unitary being is contrasted with baseline reality, and their competing claims for primacy are evaluated in an epistemological context.

We consider only the relationship of consciousness to physical reality, whether physical reality is interpreted as the brain, artificial intelligence, or the universe as a whole. The difficulties with starting the analysis with physical reality on the one hand and with consciousness on the other are delineated. We consider how one may derive from the other. Concepts of universal or pure consciousness versus local or ego consciousness are explored with the possibility that consciousness may be physically creative. We examine whether artificial intelligence can possess consciousness as an extension of the interrelationship between consciousness and the brain or material reality.

A summary of the progress of biogenetic structuralism as an approach to the social and behavioral sciences is presented, from the publication of Biogenetic Structuralism in 1974 to the present. The difficulty that many scholars have found integrating neuroan-thropology and comparative ethology into an understanding of cultural, and particularly of religious, phenomena over the past almost two decades is considered. More specifically, the articles of James Ashbrook and Mary Lynn Dell published in the same June 1993 issue of Zygon as this article are analyzed and responded to. These authors critique Eugene d'Aquili's work of integrating neuropsychology and religious experience primarily by analyzing Brain, Symbol & Experience, which d'Aquili co-authored with Charles Laughlin, Jr., and John McManus, H. Rodney Holmes's article in the same issue of Zygon analyzes the whole corpus of d'Aquili's religion and science work as it appeared over the years in the pages of Zygon and in other articles and books as well as in Brain, Symbol & Experience. This critique is likewise carefully considered and responded to. Finally a proposed trajectory of d'Aquili's (and Andrew Newberg's) future work in their ongoing project integrating neuropsychology and religious experience is elaborated. This involves, not only expansion of their general theoretical approach, but also empirical testing of hypotheses relating brain function to religious experience using PET scanning and some newer MRI visualization techniques.

This chapter extends biogenetic structural theory to a consideration of the biopsychological principles underlying higher phases of consciousness, particularly those attained by the systematic exploration of consciousness called contemplation. The concepts of psychic energy, flow, centeredness, energy circulation, and dreambody are explored as presented in various mystical traditions, and a model of the underlying neurophysiology is presented in terms of ergotropic-trophotropic tuning. The psychophysiology of various forms of meditation together with emergent peak experiences is examined and integrated into the ergotropic-trophotropic tuning model. Structural invariance of ergotropic-trophotropic tuning as well as invariant aspects of contemplation across different cultures and associated with different symbol systems is considered. Finally the nature and implications of Void Consciousness, God Consciousness, or Abssolute Unitary Being are examined.

Human ceremonial ritual is considered as an evolved behavior, one of the principal effects of which is the promotion of intragroup cohesion by decreasing or eliminating intragroup aggression. It is seen as a major determinant of what Victor Turner calls communitas in human social groups of varying extension. The frequent paradoxical effect of ritual's promoting extragroup aggression at the same time that it diminishes intragroup aggression is considered. A neuroevolutionary model of the development and social effects of ritual behavior is presented, being derived from both ethology and recent neurophysiological studies in humans.
