Abstract.In evolving to its great size the human brain has retained the distinctive features and chemistry of three kinds of brains that reflect an ancestral relationship to reptiles, early mammals, and late mammals. It constitutes, so to speak, a psychencephalon comprised of three‐brains‐in‐one, a triune brain. In the evolution from reptiles to mammals two key changes were the development of nursing and maternal care. Through the agency of “newer” parts of the brain a parental concern for family eventually generalizes not (...) only to other members of the species but to the entire biosphere, a psychological development that amounts to the evolution of responsibility and what we call conscience. Given our freedom to decide “yes” or “no” on various issues, we need not look beyond the evolving family to find a reason for being, an ethic to live by. (shrink)

Everything we experience and do as individuals is assumed to be a function of the nervous system. It is as though we were born with a total supply of algorithms for all given forms of psychic states and solutions for immediate or eventual actions. There is evidence that the forebrain is, so to speak, the central processor for psychic experience and psychologically directed behavior. Since information itself is immaterial, all forms of psychic experience represent immaterial emanations of the forebrain, including (...) sensations, perceptions, drives, affects, thoughts, and the precisely measured, cold hard facts of science. But it is to be emphasized that there can be no manufacture or communication of information without the intermediary of behaving entities. Because of the immateriality of information and the Gödel-like problem of self-reference, a central question arises as to whether or not we can ever rely on the brain with its viscoelastic properties to achieve a reliable yardstick for measuring time and space and the general nature of things. Most needed at the present time is a refined picture of the anatomy and chemistry of the brain’s circuitry accounting for its particular species of algorithms. Emphasis is given to the basic role of various proteins in generating subjective experience. Because of the role of resonance in contributing to the dynamical excitability of neural circuits, examples are given here of how it might play an algorithmic role at macroscopic, microscopic, molecular, and atomic levels. To describe this idea attention is focused on three evolutionary types of cortex that have developed in the triune evolution of the mammalian forebrain from the mammal-like reptiles to human beings.
