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 the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

What do psychedelics reveal about consciousness? What impact have psychedelics had on philosophy? In this rapidly growing area of study, this is the first volume to explore the philosophy of psychedelic experience, from a range of interdisciplinary and cross-cultural perspectives. In doing so, Philosophy and Psychedelics reveals just why the place of psychedelics in our societies should not be left to medical sciences alone, as psychedelic experience opens up new perspectives on fundamental philosophical questions relating to human experience, ethics, and the metaphysics of mind. Mapping a range of philosophical responses to the surge in studies into psychedelic drugs in the cognitive sciences, this go-to volume examines topics including psychedelics and the role of governance; psychedelics and mysticism; what psychedelics can tell us about dyadic thankfulness; and psychedelics as ways to gain new knowledge. Written by leading international scholars, the essays cover Western and non-Western traditions, from analytic philosophy to Zen Buddhism, and discuss a variety of hallucinogens, such as LSD, MDMA, and Ayahuasca, in order to build a much-needed bridge between the rapidly growing scientific research and the philosophy behind psychedelic experience.

THE NEW YORK TIMES BESTSELLER As seen on The Joe Rogan Experience! A groundbreaking dive into the role psychedelics have played in the origins of Western civilization, and the real-life quest for the Holy Grail that could shake the Church to its foundations. The most influential religious historian of the 20th century, Huston Smith, once referred to it as the "best-kept secret" in history. Did the Ancient Greeks use drugs to find God? And did the earliest Christians inherit the same, secret tradition? A profound knowledge of visionary plants, herbs and fungi passed from one generation to the next, ever since the Stone Age? There is zero archaeological evidence for the original Eucharist – the sacred wine said to guarantee life after death for those who drink the blood of Jesus. The Holy Grail and its miraculous contents have never been found. In the absence of any hard data, whatever happened at the Last Supper remains an article of faith for today’s 2.5 billion Christians. In an unprecedented search for answers, The Immortality Key examines the archaic roots of the ritual that is performed every Sunday for nearly one third of the planet. Religion and science converge to paint a radical picture of Christianity’s founding event. And after centuries of debate, to solve history’s greatest puzzle. Before the birth of Jesus, the Ancient Greeks found salvation in their own sacraments. Sacred beverages were routinely consumed as part of the so-called Ancient Mysteries – elaborate rites that led initiates to the brink of death. The best and brightest from Athens and Rome flocked to the spiritual capital of Eleusis, where a holy beer unleashed heavenly visions for two thousand years. Others drank the holy wine of Dionysus to become one with the god. In the 1970s, renegade scholars claimed this beer and wine – the original sacraments of Western civilization – were spiked with mind-altering drugs. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The constantly advancing fields of archaeobotany and archaeochemistry have hinted at the enduring use of hallucinogenic drinks in antiquity. And with a single dose of psilocybin, the psychopharmacologists at Johns Hopkins and NYU are now turning self-proclaimed atheists into instant believers. But the smoking gun remains elusive. If these sacraments survived for thousands of years in our remote prehistory, from the Stone Age to the Ancient Greeks, did they also survive into the age of Jesus? Was the Eucharist of the earliest Christians, in fact, a psychedelic Eucharist? With an unquenchable thirst for evidence, Muraresku takes the reader on his twelve-year global hunt for proof. He tours the ruins of Greece with its government archaeologists. He gains access to the hidden collections of the Louvre to show the continuity from pagan to Christian wine. He unravels the Ancient Greek of the New Testament with the world’s most controversial priest. He spelunks into the catacombs under the streets of Rome to decipher the lost symbols of Christianity’s oldest monuments. He breaches the secret archives of the Vatican to unearth manuscripts never before translated into English. And with leads from the archaeological chemists at UPenn and MIT, he unveils the first scientific data for the ritual use of psychedelic drugs in classical antiquity. The Immortality Key reconstructs the suppressed history of women consecrating a forbidden, drugged Eucharist that was later banned by the Church Fathers. Women who were then targeted as witches during the Inquisition, when Europe’s sacred pharmacology largely disappeared. If the scientists of today have resurrected this technology, then Christianity is in crisis. Unless it returns to its roots. Featuring a Foreword by Graham Hancock, the NYT bestselling author of America Before.

While maintaining an intimate link with the reader, the author Kenny Berman describes a practical shamanic method for applying sacred visionary plants for healing and transformational purposes. The ancient methods taught within are techniques he learned from the plants in the same manner as the shamans receive their knowledge. These methods were later refined and elaborated upon through his experiences working with mestizo curanderos in the Ucayali region of the Peruvian Amazon and other curanderos in Chiapis, Mexico in the 1990's. The book documents shamanic techniques for applying sacred visionary plants, namely: ayahuasca, Psilocybe mushrooms, Iboga, Salvia divinorum, peyote, San Pedro and others in a prescribed ritual manner. It begins by stating the philosophy of Psychedelic Shamanic Magick and then continues to describe all the shamanic tools (smoke, feathers, voice, scent, percussion, color, stones and more.) that are used in conjunction with willpower for creating a lasting change or to reveal transformative information. It ties all of this together into a complete ritual process beginning with the collection of the plants and culminating in the final procedure of consuming a sacred visionary plant in ceremony.

When philosophy rescued him from an emotional crisis, Jules Evans became fascinated by how ideas invented over two thousand years ago can help us today. He interviewed soldiers, psychologists, gangsters, astronauts, and anarchists and discovered the ways that people are using philosophy now to build better lives. Ancient philosophy has inspired modern communities — Socratic cafés, Stoic armies, Epicurean communes — and even whole nations in the quest for the good life. This book is an invitation to a dream school with a rowdy faculty that includes twelve of the greatest philosophers from the ancient world, sharing their lessons on happiness, resilience, and much more. Lively and inspiring, this is philosophy for the street, for the workplace, for the battlefield, for love, for life.

This handbook reviews promising applications of psychedelics in treatment of such challenging psychiatric problems as posttraumatic stress disorder, major depression, substance use disorders, and end-of-life anxiety. Experts from multiple disciplines synthesize current knowledge on psilocybin, MDMA, ketamine, and other medical hallucinogens. The volume comprehensively examines these substances' neurobiological mechanisms, clinical effects, therapeutic potential, risks, and anthropological and historical contexts. Coverage ranges from basic science to practical clinical considerations, including patient screening and selection, dosages and routes of administration, how psychedelic-assisted sessions are structured and conducted, and management of adverse reactions.

Humans have always sought ecstatic experiences - moments where they go beyond their ordinary self and feel connected to something greater than them. Such moments are fundamental to human flourishing, but they can also be dangerous. Beginning around the Enlightenment, western intellectual culture has written off ecstasy as ignorance or delusion. But philosopher Jules Evans argues that this diminishes our reality and denies us the healing, connection and meaning that ecstasy can bring. He sets out to discover how people find ecstasy in a post-religious culture, how it can be good for us, and also harmful. Along the way, he explores the growing science of ecstasy, to help the reader - and himself - learn the art of losing control. Jules' exploration of ecstasy is an intellectual and emotional odyssey balancing personal experience, interviews and readings from ancient and modern philosophers that will change the way you think about how you feel. From Aristotle and Plato, via the Bishop of London and Sister Bliss, radical jihadis and Silicon Valley transhumanists, The Art of Losing Control is a funny and life-enhancing journey through under-explored terrain.
