Proceeding from a philosophical interpretation of negative theology as performatively undermining our seeming understanding of the absolute and thereby evoking a transformative experience, this paper emphasises the philosophical significance of negative theology by linking it to Karl Jaspers’ notion of the universal limit situation of existence. Against this background, an analysis of mystical and psychotic experiences shows how certain similarities between the two can be understood as constituting a particular mental state in which the universal limit situation is experienced personally. (...) Moreover, experiencing the limit situation, be it through this mental state or through certain moods or feelings, can be transformative and may lead to an attitude of groundless trust that acknowledges the incomprehensibility of the human condition. The paper argues that this reading of negative theology provides a better understanding of the parallels between mysticism and psychosis and may be fruitfully applied in therapy. (shrink)

Scientific interest in drug-induced mystical experiences reemerged in the 1990s. This warrants reexamining the philosophical issues surrounding such studies: Do psychedelic drugs cause mystical experiences? Are drug-induced experiences the same in nature as other mystical experiences? Does the fact that mystical experiences can be induced by drugs invalidate or validate mystical cognitive claims? Those questions will be examined here. An overview of the scientific examination of drug-induced mystical experiences is included, as is a brief overview of the history of the (...) use of psychedelic drugs in religion. (shrink)

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)

The term entheogen refers to drugs—including the artificial substances and active principles drawn from them—which are known to produce ecstasy and have been used traditionally in certain religious and shamanic contexts. The entheogenic experiences provoked by entheogens are described by users in myriad ways, including in spiritual, religious, philosophical, and secular contexts. Entheogenic experiences have shown that they can create opportunities for individuals to generate meaning, including novel philosophical insights, which users claim to gain by way of experience. As such, (...) entheogenic experiences exhibit the ability to influence a change in a user’s fundamental philosophical commitments, or live options, including their ethical dispositions. Given that these new live options are rooted in experience, their veracity gains further credence for users than those commitments they have come to hold by way of abstraction. By philosophically investigating the phenomenology of entheogenic experiences, this work argues that entheogens have ethical import. (shrink)
