This is a pioneering cognitive psychological study of Ayahuasca, a plant-based Amazonian psychotropic brew. Benny Shanon presents a comprehensive charting of the various facets of the special state of mind induced by Ayahuasca, and analyzes them from a cognitive psychological perspective. He also presents some philosophical reflections. Empirically, the research presented in this book is based on the systematic recording of the author's extensive experiences with the brew and on the interviewing of a large number of informants: indigenous people, shamans, members of different religious sects using Ayahuasca, and travellers. In addition to its being the most thorough study of the Ayahuasca experience to date, the book lays the theoretical foundations for the psychological study of non-ordinary states of consciousness in general.

A pioneering study of the phenomenology of the special state of mind induced by Ayahuasca, a plant-based Amazonian psychotropic brew. The author's research is based both on extensive firsthand experiences with Ayahuasca, and on interviews conducted with a large number of informants coming from different places and backgrounds.

In this wide-ranging book the author presents his critique of the contemporary portrayal of cognition, an analysis of the conceptual foundations of cognitive science and a proposal for a new concept of the mind. Shanon argues that the representational account is seriously lacking and that far from serving as a basis of cognitive activity, representations are the products of such activity. He proposes an alternative view of the mind in which the basic capability of the cognitive system is not the manipulation of symbols but rather action in the world. His book offers a different outlook on the phenomenon of consciousness and presents a new conception of psychological theory and explanation. This revised second edition includes a new postscript.
