In praise of the hand: A philosopher considers the crucial role of the hand in human evolution, particularly with respect to language. “McGinn is an ingenious philosopher who thinks like a laser and writes like a dream.” —Steven Pinker This book is a hymn to the hand. In Prehension, Colin McGinn links questions from science to philosophical concerns to consider something that we take for granted: the importance of the hand in everything we do. Drawing on evolutionary biology, anatomy, archaeology, linguistics, psychology, and philosophy, among other disciplines, McGinn examines the role of the hand in shaping human evolution. He finds that the development of our capacity to grasp, to grip, to take hold (also known as prehension) is crucial in the emergence of Homo sapiens. The human species possesses language, rational thought, culture, and a specific affective capacity; but there was a time when our ancestors had none of these. How did we become what we so distinctively are, given our early origins? McGinn, following Darwin and others, calls the hand the source of our biological success. When our remote ancestors descended from trees, they adopted a bipedal gait that left the hands free for other work; they began to make tools, which led to social cooperation and increased brain capacity. But McGinn goes further than others in arguing for the importance of the hand; he speculates that the hand played a major role in the development of language, and presents a theory of primitive reference as an outgrowth of prehension. McGinn sings the praises of the hand, and evolution, in a philosophical key. He mixes biology, anthropology, analytical philosophy, existential philosophy, sheer speculation, and utter amazement to celebrate humans' achievement of humanity.

This volume introduces a methodology, based on a systematic, in-depth study of prehension and hafting traces on experimental stone artifacts. The author proposes a number of distinctive macro- and microscopic wear traits for identifying handheld tools.

Volume 3.

The simple task of grasping objects has been studied for centuries by scientists, therapists and engineers who have tried to understand and duplicate the versatility of the human hand. Using an interdisciplinary approach and new framework for looking at prehension, the authors uncover the subleties of the amazing interaction between the hand and the brain. They draw from such diverse fields as experimental psychology, kinesiology, robotics, neural networks, artificial intelligence, neuropsychology and rehabilitation. A triangle strategy is presented, starting from conceptual models that suggest both experimental and computational models. Chapters describe the multiple postures established by the hand, phases in the dynamic process of reaching for, grasping and manipulating various objects, and the constraints acting on such activity.Appendices provide the complete anatomy of the upper limb, the basics of computational modelling, and the fundamentals of prosthetic and dextrous robot hands. The ultimate goal of this book is to develop a common vocabularly for multidisciplinary researchers who strive to understand a system as complex as the hand under the control of the human brain.
