The Gifford Lectures were established in 1885 at the universities of St Andrews, Glasgow, Aberdeen and Edinburgh to promote the discussion of 'Natural Theology in the widest sense of the term - in other words, the knowledge of God', and some of the world's most influential thinkers have delivered them. The 1901–2 lectures given in Edinburgh by American philosopher William James are considered by many to be the greatest in the series. The lectures were published in book form in 1902 (...) and have been reprinted many times. James, who was educated in the United States and Europe, and spent much of his career teaching philosophy at Harvard, was very influential in the development of modern psychology, and in these twenty lectures he explores the personal experience of religion. Some of the topics include religion and neurology, 'the sick soul', saintliness, and mysticism. (shrink)

The Perennial Philosophy is defined by its author as "The metaphysic that recognizes a divine Reality substantial to the world of things and lives and minds." With great wit and stunning intellect, Aldous Huxley examines the spiritual beliefs of various religious traditions and explains them in terms that are personally meaningful.

2010 Reprint of 1905 edition.This work is the magnum opus of Bucke's career, a project that he researched and wrote over many years. In it, Bucke described his own experience, that of contemporaries, and the experiences and outlook of historical figures including Buddha, Jesus, Paul, Plotinus, Muhammad, Dante, Francis Bacon, and William Blake. Bucke developed a theory involving three stages in the development of consciousness: the simple consciousness of animals; the self-consciousness of the mass of humanity ; and cosmic consciousness (...) - an emerging faculty and the next stage of human development. Among the effects of this progression, he believed he detected a lengthy historical trend in which religious conceptions and theologies had become less and less fearful. A classic work. (shrink)

This is a detailed portrait of how an aboriginal tribe of the remote Amazonian region understands the cosmic dimensions of their partnership with the rainforest. Anthropologist Gerardo Reichel-Dolmatoff, who spent most of his life working in Colombia among the Indian tribes of the North-West Amazon, explores the world-view of the Tukano Indians: their view of the forest as a model of the cosmos; the master of the animals; their complex and multi-dimensional bond with their environment; and their social and sexual (...) restrictions in order to harmonise with the rainforest.

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.

This paper is part of an ongoing project devoted to the investigation of the psychotropic brew Ayahuasca from a cognitive-psychological perspective. This perspective contrasts with those of practically all investigations of Ayahuasca which pertain either to the natural sciences-notably botany, pharmacology, brain science and clinical medicine-or to anthropology. Here, I discuss the visualizations induced by Ayahuasca from a structural, as opposed to contentual, point of view. A typology of the structural forms in which visualizations may appear is drawn. Also examined (...) are the various types of interaction a person can have with his/her visions and aspects pertaining to the semantics of visions and their narrative structure. The distinctions drawn are readily applicable to hallucinatory and visionary experiences induced by other agents and in other contexts. Thus, the present typology may be regarded as presenting the foundations for the cognitive-psychological study of such experiences at large. (shrink)

Temporality is a fundamental determinant of human cognition. There are, however, states of mind in which people feel that temporality changes radically and perhaps even becomes irrelevant. Here I attempt a typology of the patterns of such non-ordinary temporal experiences. The discussion is based on a phenomenological study of the special state of consciousness induced by Ayahuasca, a powerful Amazonian psychoactive brew.

This paper is part of a comprehensive research project whose aim is to study the phenomenology of the special state of mind induced by the psychoactive Amazonian potion ayahuasca. Here, I focus on those aspects of the ayahuasca experience that are related to basic features of the human consciousness. The effects of the potion are discussed in terms of a conceptual framework characterizing consciousness as a cognitive system defined by a set of parameters and the values that they take. In (...) various theoretical contexts, these values have been assumed to be basic, paradigmatic properties of human consciousness. The phenomenological data pertaining to ayahuasca indicate that the features at hand can be modified. Following earlier suggestions by William James and Aldous Huxley, I conclude that any general theory of consciousness should be based not only on the study of so-called ordinary consciousness, but also on that of non-ordinary states.

This paper examines the standard conceptualizations of the notion of hallucination in light of various non-ordinary phenomenological patterns associated with altered states of consciousness induced by psychoactive agents. It is argued that in general, the conceptualizations encountered in the literature do not do justice to the richness and complexity that the psychological phenomenology actually exhibits. A close inspection of this phenomenology reveals some pertinent distinctions which are usually not made in the scientific literature. On the one hand, the discussion is (...) based on first-hand experiences and, on the other hand, it is grounded in empirical and theoretical cognitive investigations of the phenomenology of human consciousness. Theoretically, the discussion is grounded in an approach highlighting the centrality of experience, meaning and action in cognition. (shrink)

A new phenomenological framework for the characterization of human consciousness is presented. The theory is introduced in several stages - making distinctions concerning types of consciousness, levels, parameters, functional features and dynamic operations. The phenomenology encompasses both ordinary and non-ordinary states of mind. It appears that in its totality the phenomenology of human consciousness comprises a well- structured system exhibiting coherence and internal structure. In addition, this framework presents a new approach for cognitive research, methodologically as well as theoretically. Observations (...) concerning the intellectual challenge of consciousness are.

The article on synaesthesia by Ramachandran and Hubbard is comprehensive and intellectually stimulating. In this commentary, I would like to present some empirical data not discussed in R&H and to raise some theoretical questions relating to ideas proposed in this article. My comments will be divided into three sections, or - rather - three stories, which correspond to three, independent and different, occasions in my career in which I found myself dealing with synaesthesia. Each of these stories carries a moral (...) that adds to the picture of synaesthesia drawn in R&H. (shrink)
