At last, a worthy antidote to the noxious trend that explains all human consciousness and behaviour in terms of the evolution and activities of the brain alone! Cognitive science, evolutionary psychology, and neurophilosophy, while adding complexity, have embraced the assumption that life unfolds primarily on the basis of evolving, interacting genes. But this view is unbalanced at best. Greenspan and Shanker remind us that opposition to it need not imply mysticism, idealism, or anything spooky. They state the predominance of cultural learning passed on from generation to generation, its content always changing and never complete.
A second theme of the book is that it supplies strong evidence that rationality and cognition are not opposed to emotion, but are in fact the fulfillment of the emotional education hopefully received by every healthy child. To think is to emote, but it is refined emotion that functions in a controlled manner. This is an antidote to the Cartesians, Freudians, and perhaps even Piagetians who have insisted that, developmentally, the rise of reason in maturity overcomes primitive or childish emotional drives.
The authors propose that such emotional learning has culturally evolved over millions of years, with reversals here and dead ends there. Each generation passes on its cultural truths primarily through interactions between infant and mother or other intimate caregivers. But each generation may also contribute in subtle ways to this body of learning or, on occasion, subtract from it. Every child is regarded as recapitulating, in a matter of years or months, the learning that culture achieved over millions of years. Language is the primary example here.
They find little evidence that things so central as language or personal memory are themselves innate, though clearly the capacity to achieve them has become genetically based. The nature-nurture debate becomes appropriately complexified. The antidote to genetic imperialism involves showing that experience determines genetics more than genetics determines experience.
Greenspan and Shanker identify 16 stages of individual f/e (functional/emotional) development, plus a timeline of 12 steps for the f/e evolution of human cognition, outdoing the three steps of Merlin Donald (1991). The neologism “meme” is thankfully not used, though they see human behaviour and the quality of conscious experience as arising from culturally transmitted learning. They cite Terrence Deacon (1997) approvingly, so presumably accept that structural brain adaptations occur along with the slow invention of formal language structures. They don't deny the brain’s influence, but see it as a dance with learning, and the lead is clearly learning.
Greenspan is an expert on infant care and autism, while Shanker, apparently a Wittgenstein scholar, specializes in studying the symbolic activities of trained apes (bonobos). Perhaps as a consequence of their particular expertise, they spend less time on the slow discovery and improvement of speech, symbolism, and thought in early humanity than they do on the rapid appearance of these capacities in individual upbringing. They appear to accept too early and gradual an origin for formal human language, not being critical enough of nonhuman communication or of early paleoanthropological finds. As a result, many ambiguous discoveries are treated as proofs of the presence of abstract ideation. It is not noted that the islands of discovery, seeming to indicate a very early emergence of symbolic interaction, are just that — islands. There is (as yet) no indication of continuity in such activities over succeeding millennia. Nor do the authors deal with early humanity’s immersion in the sacred; language is accepted as having been invented to meet functional needs and for the pleasure of communicating.
Another reservation I have is that all the juice is in the first two parts of the book. Greenspan and Shanker lay out their case in the first 184 pages, leaving the rest for sometimes excruciating exegesis or jumps into global recommendations. Indeed, they emphasize so strongly "the hand that rocks the cradle rules the world" that they have added a hopeful final chapter to guide us all toward Global Interdependency through the education of emotional response in every child's first year. Alas, we have many hurdles to overcome before every child on the planet can receive the loving, interactive attention that will lead it to the authors' highest stage of development in old age: "...true wisdom free from the self-centred and practical worries of earlier stages" (p. 91) and a peaceful world in general.
Optimistic? Sure, but this tome is still recommended for its important defence of culture and learning.
