"In this provocative new study one of the world's most distinguished anthropologists proposes that an understanding of cognitive science enriches, rather than threatens, the work of social scientists. Maurice Bloch argues for a naturalist approach to social and cultural anthropology, introducing developments in cognitive sciences such as psychology and neurology and exploring the relevance of these developments for central anthropological concerns: the person or the self, cosmology, kinship, memory and globalisation. Opening with an exploration of the history of anthropology, Bloch shows why and how naturalist approaches were abandoned and argues that these once valid reasons are no longer relevant. Bloch then shows how such subjects as the self, memory and the conceptualisation of time benefit from being simultaneously approached with the tools of social and cognitive science. Anthropology and the Cognitive Challenge will stimulate fresh debate among scholars and students across a wide range of disciplines"--

The third volume in a projected four-part series on the evolution of human intelligence, a series acknowledged by opponents and supporters alike as one of the most important recent investigations into the sources and nature of human intelligence. Professor Itzkoff first sets forth the evolutionary facts as a beacon to illuminate his biological theory of variable intelligence. Filling out the evidence from the psychological and brain sciences presented in THE FORM OF MAN and TRIUMPH OF THE INTELLIGENT, he here develops a full-scale model of the mind that more fully explains the relationship between I.Q. and the broader expressions of human intelligence as experienced in daily life. (His model of variable intelligence further delves into the historical consequences of our ancient biological and psychoneurological heritage. Issues such as gender, race, and ethnic variability are treated factually and responsibly, taking into account the full range of empirical evidence available to scholars.) The result is a theory having three complementary bodies of evidence - evolutionary, psychoneurological, and historical - building into a perspective on the factual «why» of human intellectual differences. These differences can best be observed in the richness and diversity of individual personality as well as in the cultures of our world. Itzkoff here takes the first tentative steps toward a biological explanation of the nature and structure of culture. WHY HUMANS VARY IN INTELLIGENCE is an appeal for the rational study of human nature, a plea to allow for further nonideological research into this most crucial area of contemporary concern.

The Form of Man presents a new interpretation, consonant with Darwinian evolutionary theory, recent evidence of human evolution, and the realities of cultural life. The exploration begins with the study of the form of life, traversing the tentative gropings of intelligent organic matter in its long struggle to establish itself as life's major adaptation. Seymour Itzkoff explains how intelligence as an adaptation is the slowest and most complex of life's vehicles to escape the degradation of energy predicted by the second law of thermodynamics. Dr. Itzkoff proposes that two evolutionary processes were keys to shaping human nature along its own particular path. Paedomorphosis (infantilization) explains many of man's unique anthropoid features. Orthoselection (evolution in a straight line) allows us to complete a picture of mankind's rapid catapult in brain size expansion almost into our own day. Both concepts reveal how man could have escaped the close selective honing that would have made him a far more practical creature. The final dramatic moment came with the sudden icy extrusion of a super sapient, Homo sapiens sapiens, sometime after 100,000 B.P. It ransformed the structure of all existing transitional hominids and created the conditions for both the growth of civilization and the paradoxical dilemmas and tragedies in our present polyglot humanity.
