The anthropology of consciousness is a field of enormous and demanding scope. In this article, there is no attempt to address all of the current trends in thinking and research; rather, the aim was to draw a line through the field that extends from the 19th century and European philosophies to some contemporary expressions of those philosophies in social science research. In particular, taking the original project of Edmund Husserl, an approach to the phenomenological investigation of the nature of consciousness (...) and, in addition, states of consciousness is proposed in the form of “existential grammars.” The treatment is propaedeutic: The ideas presented here are part of an on-going, long-term project tied to cross-cultural and experimental research on consciousness. However, the short-term outcomes are promising in elucidating the foundational questions not only about consciousness but also about specific areas of interest such as healing and the nature of scientific investigation itself. One important direction in this work is to illuminate, where possible, the pre-reflective rationalities of human experience, of consciousness itself, in such a way that we might generate codes of consciousness ultimately not as the equivalent of genetic models, but as descriptors of the core matrix of consciousness out of which alterations of consciousness might be better understood.

Ayahuasca is a psychoactive brew from Amazonas, popularized in the last decades in part through transnational religious networks, but also due to interest in exploring spirituality through altered states of consciousness among academic schools and scientific researchers. In this article, the author analyzes the relation between science and religion proposing that the “demarcation problem” between the two arises from the relations among consciousness, intentionality, and spirituality. The analysis starts at the beginning of modern science, continues through the nineteenth century, and (...) then examines the appearance of new schools in psychology and anthropology in the countercultural milieu of the 1960s. The author analyzes the case of ayahuasca against this historical background, first, in the general context of ayahuasca studies in the academic field. Second, he briefly describes three cases from Spain. Finally, he discusses the permeability of science to “spiritual ontologies” from an interdisciplinary perspective, using insights from social and cognitive sciences. (shrink)
