  1. The Psychedelic Gospels: The Secret History of Hallucinogens in Christianity.Jerry B. Brown & Julie M. Brown - 2016 - Rochester, Vermont: Park Street Press / Inner Traditions.
    hroughout medieval Christianity, religious works of art emerged to illustrate the teachings of the Bible for the largely illiterate population. What, then, is the significance of the psychoactive mushrooms hiding in plain sight in the artwork and icons of many European and Middle-Eastern churches? Does Christianity have a psychedelic history? -/- Providing stunning visual evidence from their anthropological journey throughout Europe and the Middle East, including visits to Roslyn Chapel and Chartres Cathedral, authors Julie and Jerry Brown document the role (...)

  2. Review of Nicolas Langlitz's Neuropsychedelia: The Revival of Hallucinogen Research Since the Decade of the Brain. [REVIEW]Meg Stalcup - 2015 - Somatosphere 2015.
    Humphry Osmond wrote to Aldous Huxley in 1956 proposing the term “psychedelic,” coined from two Greek words to mean “mind manifesting.” The scholars, one a psychiatrist and the other a celebrated novelist and philosopher, were exuberant about the potential of drugs for accessing the mind. Huxley favored a phrase from William Blake: -/- If the doors of perception were cleansed everything would appear to man as it is, infinite. -/- He postulated that psychedelics disturbed the “cerebral reducing valve” (1954), and (...)

  3. The Varieties of Psychedelic Epistemology.Chris Letheby - 2019 - In Nikki Wyrd, David Luke, Aimee Tollan, Cameron Adams & David King (eds.), Psychedelicacies: more food for thought from Breaking Convention. Strange Attractor Press.
    Recent scientific research suggests that altered states of consciousness induced by classic psychedelic drugs can cause durable psychological benefits in both healthy and patient populations. The phenomenon of ‘psychedelic transformation’ has many philosophically provocative aspects, not least of which is the claim commonly made by psychedelic subjects that their transformation is centrally due to some kind of learning or knowledge gain. Can psychedelic experiences really be a source of knowledge? From the vantage point of philosophical materialism or naturalism, a negative (...)

  4. Looking for the Self: Phenomenology, Neurophysiology and Philosophical Significance of Drug-induced Ego Dissolution.Raphaël Millière - 2017 - Frontiers in Human Neuroscience 11:1-22.
    There is converging evidence that high doses of hallucinogenic drugs can produce significant alterations of self-experience, described as the dissolution of the sense of self and the loss of boundaries between self and world. This article discusses the relevance of this phenomenon, known as “drug-induced ego dissolution (DIED)”, for cognitive neuroscience, psychology and philosophy of mind. Data from self-report questionnaires suggest that three neuropharmacological classes of drugs can induce ego dissolution: classical psychedelics, dissociative anesthetics and agonists of the kappa opioid (...)

  5. Cognitive enhancement, cheating, and accomplishment.Rob Goodman - 2010 - Kennedy Institute of Ethics Journal 20 (2):pp. 145-160.
    In an essay on performance-enhancing drugs, author Chuck Klosterman (2007) argues that the category of enhancers extends from hallucinogens used to inspire music to steroids used to strengthen athletes—and he criticizes those who would excuse one means of enhancement while railing against the other as a form of cheating: After the summer of 1964, the Beatles started taking serious drugs, and those drugs altered their musical performance. Though it may not have been their overt intent, the Beatles took performance-enhancing drugs. (...)

  6. Psychedelics and Moral Psychology: The Case of Forgiveness.Samir Chopra & Chris Letheby - forthcoming - In Chris Letheby & Philip Gerrans (eds.), Philosophical Perspectives on Psychedelic Psychiatry. Oxford University Press.
    Several authors have recently suggested that classic psychedelics might be safe and effective agents of moral enhancement. This raises the question: can we learn anything interesting about the nature of moral experience from a close examination of transformative psychedelic experiences? The interdisciplinary enterprise of philosophical psychopathology attempts to learn about the structure and function of the “ordinary” mind by studying the radically altered mind. By analogy, in this chapter we argue that we can gain knowledge about the everyday moral life (...)

  7. Psychedelics: Recent Philosophical Discussions.Chris Letheby - 2017 - In Thomas Schramme & Steven Edwards (eds.), Handbook of the Philosophy of Medicine. Springer.
    “Classic”, serotonergic psychedelic drugs such as LSD and psilocybin are the objects of renewed attention in science and psychiatry. A recent spate of research has produced evidence that psychedelics might be safe and effective adjuncts to the treatment of mood and addictive disorders, agents of positive psychological change in healthy subjects, and valuable tools for studying the neural mechanisms of perception and cognition. This chapter surveys three philosophical debates that have arisen in response to this “renaissance” of psychedelic research. The (...)

  8. Psilocybin, LSD, Mescaline and drug-induced synesthesia.Dimitria Electra Gatzia & Berit Brogaard - 2016 - In Victor R. Preedy (ed.), The Neuropathology Of Drug Addictions And Substance Misuse. Elsevier.
    Studies have shown that both serotonin and glutamate receptor systems play a crucial role in the mechanisms underlying drug-induced synesthesia. The specific nature of these mechanisms, however, continues to remain elusive. Here we propose two distinct hypotheses for how synesthesia triggered by hallucinogens in the serotonin-agonist family may occur. One hypothesis is that the drug-induced destabilization of thalamic projections via GABAergic neuronal circuits from sensory areas leads to a disruption of low-level, spontaneous integration of multisensory stimuli. This sort of integration (...)

  9. Naturalistic Entheogenics.Chris Letheby - 2022 - Philosophy and the Mind Sciences 3.
    In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of “classic” psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatment relies essentially on the induction of non-naturalistic metaphysical beliefs, rendering it epistemically objectionable. I begin the précis by summarizing material from chapters two and three (...)

  11. Philosophy of Psychedelics.Chris Letheby - 2021 - Oxford, UK: Oxford University Press.
    Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...)

  12. Self unbound: ego dissolution in psychedelic experience.Chris Letheby & Philip Gerrans - 2017 - Neuroscience of Consciousness 3:1-11.
    Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound.

  13. Philosophy and classic psychedelics: A review of some emerging themes.Chris Letheby & Jaipreet Mattu - 2022 - Journal of Psychedelic Studies 5 (3):166-175.
    Serotonergic (or “classic”) psychedelics have struck many researchers as raising significant philosophical questions that, until recently, were largely unexplored by academic philosophers. This paper provides an overview of four emerging lines of research at the intersection of academic philosophy and psychedelic science that have gained considerable traction in the last decade: selfless consciousness, psychedelic epistemology, psychedelic ethics, and spiritual/religious naturalism. In this paper, we highlight philosophical questions concerning (i) psychedelics, self-consciousness, and phenomenal consciousness, (ii) the epistemic profile of the psychedelic (...)

  15. Review of Steven D. Hales' Book: Relativism and the Foundations of Philosophy. [REVIEW]Manhal Hamdo - 2018 - INTERNATIONAL JOURNAL OF RESEARCH CULTURE SOCIETY 2 (1):200-204.
    This review is a critical evaluation of the main points of Steven D. Hales’ significant book: Relativism and the Foundations of Philosophy. To that end, I will first summarize his major line of argument pointing out to the richness and significance of the book. After that, I will argue that Hales’ account of intuition is subject to the challenge shown by some recent works written on the topic, and that it postulates a concept of knowledge that opposes Gettier’s one, without (...)
