A mere "symbol" of medicine--the sugar pill, saline injection, doctor in a white lab coat--the placebo nonetheless sometimes produces "real" results. Medical science has largely managed its discomfort with this phenomenon by discounting the placebo effect, subtracting it as an impurity in its data through double-blind tests of new treatments and drugs. This book is committed to a different perspective--namely, that the placebo effect is a "real" entity in its own right, one that has much to teach us about how symbols, settings, and human relationships literally get under our skin.

Anne Harrington's introduction and a historical overview by Elaine Shapiro and the late Arthur Shapiro, which open the book, review the place of placebos in the history of medicine, investigate the current surge in interest in them, and probe the methodological difficulties of saying scientifically just what placebos can and cannot do. Combining individual essays with a dialogue among writers from fields as far-flung as cultural anthropology and religion, pharmacology and molecular biology, the book aims to expand our ideas about what the placebo effect is and how it should be seen and studied. At the same time, the book uses the challenges and questions raised by placebo phenomena to initiate a broader interdisciplinary discussion about our nature as cultural animals: animals with minds, brains, and bodies that somehow manage to integrate "biology" and "culture," "mechanism" and "meaning," into a seamless whole.

A profound exploration of the external influences that shape human consciousness, from healing rituals to digital devices

In this voyage through thousands of years of psychosomatic healing, distinguished anthropologist and sociologist Roger Bartra examines the placebo effect as a key to our understanding of human consciousness. Shamans and Robots demonstrates how biology and technology become intertwined within human culture by using the various histories of ritual and symbolic healing to speculate about future developments in artificial intelligence.

Charting the extensive history of the placebo effect through medieval healing, shamanism, and early psychoanalytic practices, Bartra posits that consciousness is not simply the province of the mind but something equally shaped by external systems and objects. He finds evidence of this “exocerebrum”—the extension of our brains outside the body—in the shamanistic concept of the placebo, in which external objects heal our bodies, and in modern technical devices like prostheses or robots, whose development of a mechanical consciousness would have to mimic, and in turn elucidate, the processes involved in the creation of consciousness in humans. Through this radical concept, he analyzes digital media’s relationship to the functions of the human brain and probes the possibility of artificial consciousness.

Both a look at the human body’s potential to restore itself and a profound reflection on the curative power of symbolic structures, Shamans and Robots explores how our technologies increasingly serve as extensions of our cognitive selves.
