This paper develops more specific details on how natural mental‐function might evolve within a wholly‐material brain system, depending entirely on “self‐organization” operating within á reasonably consistent environment. It is assumed that mental development can, in principle, be explained in detailed mechanistic terms. The attempt is then made to give the outlines of such an explanation, drawing on existing physiological knowledge, and considerations of the practical “design” difficulties which such a system would necessarily have to face. RNA‐like codeable strings are seen as the basic memory elements (rather than adaptable synapses). “Concepts” are explained as Piagetian mental models, built up in explained stages due to interaction with the real object, and encoded on the linear elements. Coordination between these elements is seen as biochemical but with the added available intermediary of electrically mediated signals, allowing coordination at a distance. The likelihood that subsequent developmental periods may recapitulate the same overall strategy is considered.
