In this groundbreaking work, three experts—a mycologist, a chemist and a historian—argue persuasively that the sacred potion given to participants in the course of the ritual contained a psychoactive entheogen. The authors then expand the discussion to show that natural psychedelic agents have been used in spiritual rituals across history and cultures. Although controversial when first published in 1978, the book’s hypothesis has become more widely accepted in recent years, as knowledge of ethnobotany has deepened. The authors have played critical roles in the modern rediscovery of entheogens, and The Road to Eleusis presents an authoritative exposition of their views. The book’s themes of the universality of experiential religion, the suppression of that knowledge by exploitative forces, and the use of psychedelics to reconcile the human and natural worlds make it a fascinating and timely read. This 30th anniversary edition includes an appreciative preface by religious scholar Huston Smith and an updated exploration of the chemical evidence by Peter Webster.

    Nor is it a collection of bizarre facts, though the Angel of the Bizarre might well find himself at home in it. It is not a scientific contribution, a vehicle for an exotic teaching, a testament, a document, a fable. It is simply an account - at times figurative, at times factual - of a first excursion into some as yet scarcely explored realms of consciousness. The Morning of the Magicians is a classic of radical literature, a book that has challenged assumptions and conventional knowledge for decades. It has shaken the foundations of beliefs all over the world and may be the most influential book published in the twentieth century. Louis Pauwels and Jacques Bergier spent years searching "through all the regions of consciousness, to the frontiers of science and tradition" and opened their minds to any fact or theory that went beyond the frontier of current theories. The result is this remarkable work, and the stream of possibilities that it contains: Do mutants exist, are they a future form of man? Does extrasensory perception reveal that human consciousness has advanced beyond its currently accepted limits? What connects the ancient art of alchemy and modern atomic physics?

    The original manuscript of The Book of the Law was re-scanned for this edition, using the latest technology, for the clearest facsimile possible.Aleister Crowley devoted twenty-five years to writing and producing the four parts of this book. It is his magnum opus, in which he systematically expounds the mystical and magical theories and techniques taught in his magical orders, the A∴A∴ and the O.T.O.This profusely illustrated new edition brings together the complete texts of all four parts of Liber ABA (Book 4) in one volume under the overall title Magick. This edition incorporates Crowley`s own additions, corrections, and annotations, and restores dozens of passages omitted from all earlier editions.Magick is the fundamental textbook of modern magick in the New Æon. It also has invaluable teachings for students of Yoga and meditation. Crowley mastered the practices of Yoga during his studies in the East, and writes about them lucidly, without recourse to the imprecise language of mysticism.Beginning with a discussion of the universal origin of world religions in mystical revelation, Magick then explores the theory and practice of mysticism and magick in the light of modern scientific thought. Crowley`s own revelation, The Book of the Law, is then treated as a case study, with an autobiographical study of events leading to its reception.Extensively cross-referenced and annotated, this edition features over 100 diagrams and photographs, as well as a glossary, bibliography, and detailed index.

    Peter Watson's hugely ambitious and stimulating history of ideas from deep antiquity to the present day—from the invention of writing, mathematics, science, and philosophy to the rise of such concepts as the law, sacrifice, democracy, and the soul—offers an illuminated path to a greater understanding of our world and ourselves.

    John Gray's stimulating and extremely enjoyable new book describes the rich, complex world of the atheist tradition, a tradition which he sees as in many ways as rich as that of religion itself, as well as being deeply intertwined with what is so often crudely viewed as its 'opposite'.The result is a book that sheds an extraordinary and varied light on what it is to be human and on the thinkers who have, at different times and places, battled to understand this issue.

    The book takes us from the Greeks' earliest scientific observations through Einstein and beyond in an inspiring celebration of human curiosity. It ends with the quest for the Higgs boson, nicknamed the God Particle, which scientists hypothesize will help unlock the last secrets of the subatomic universe. With a new preface by Lederman, The God Particle will leave you marveling at our continuing pursuit of the infinitesimal.

    In A Guide to the Good Life, William B. Irvine plumbs the wisdom of Stoic philosophy, one of the most popular and successful schools of thought in ancient Rome, and shows how its insight and advice are still remarkably applicable to modern lives. In A Guide to the Good Life, Irvine offers a refreshing presentation of Stoicism, showing how this ancient philosophy can still direct us toward a better life. Using the psychological insights and the practical techniques of the Stoics, Irvine offers a roadmap for anyone seeking to avoid the feelings of chronic dissatisfaction that plague so many of us. Irvine looks at various Stoic techniques for attaining tranquility and shows how to put these techniques to work in our own life. As he does so, he describes his own experiences practicing Stoicism and offers valuable first-hand advice for anyone wishing to live better by following in the footsteps of these ancient philosophers. Readers learn how to minimize worry, how to let go of the past and focus our efforts on the things we can control, and how to deal with insults, grief, old age, and the distracting temptations of fame and fortune. We learn from Marcus Aurelius the importance of prizing only things of true value, and from Epictetus we learn how to be more content with what we have. Finally, A Guide to the Good Life shows readers how to become thoughtful observers of their own life. If we watch ourselves as we go about our daily business and later reflect on what we saw, we can better identify the sources of distress and eventually avoid that pain in our life. By doing this, the Stoics thought, we can hope to attain a truly joyful life.

    In the tradition of unsolved historical mysteries like David Grann's Killers of the Flower Moon and Douglas Preston's The Lost City of the Monkey God, Brian Muraresku’s 10-year investigation takes the reader through Greece, Germany, Spain, France and Italy, offering unprecedented access to the hidden archives of the Louvre and the Vatican along the way.In The Immortality Key, Muraresku explores a little-known connection between the best-kept secret in Ancient Greece and Christianity. This is the real story of the most famous human being who ever lived (Jesus) and the biggest religion the world has ever known. Today, 2.4 billion people are Christian. That's one third of the planet. But do any of them really know how it all started?Before Jerusalem, before Rome, before Mecca—there was Eleusis: the spiritual capital of the ancient world. It promised immortality to Plato and the rest of Athens's greatest minds with a very simple formula: drink this potion, see God. Shrouded in secrecy for millennia, the Ancient Greek sacrament was buried when the newly Christianized Roman Empire obliterated Eleusis in the fourth century AD.Renegade scholars in the 1970s claimed the Greek potion was psychedelic, just like the original Christian Eucharist that replaced it. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The rapidly growing field of archaeological chemistry has proven the ancient use of visionary drugs. And with a single dose of psilocybin, the psycho-pharmacologists at Johns Hopkins and NYU are now turning self-proclaimed atheists into instant believers. No one has ever found hard, scientific evidence of drugs connected to Eleusis, let alone early Christianity. Until now.Armed with key documents never before translated into English, convincing analysis, and a captivating spirit of quest, Muraresku mines science, classical literature, biblical scholarship and art to deliver the hidden key to eternal life, bringing us to what clinical psychologist William Richards calls "the edge of an awesomely vast frontier."Featuring a Foreword by Graham Hancock, the New York Times bestselling author of America Before: The Key to Earth's Lost Civilization.

    The sheer fact that over half of Americans don't believe in evolution (to say nothing of the number of Congressmen who don't believe in climate change) and the resurgence of religious prejudices and strictures as factors in politics, education, medicine, and social policy make the need for this book urgent.Religion and science compete in many ways to describe reality - they both make "existence claims" about what is real - but they use different tools to meet this goal. In his elegant, provocative, and direct argument, leading evolutionary biologist and bestselling author Jerry Coyne lays out in clear, patient, dispassionate details why the toolkit of science, based on reason and empirical study, is reliable, while that of religion - including faith, dogma and revelation - is unreliable and leads to incorrect, untestable, or conflicting conclusions. Indeed, by relying on faith, religion renders itself incapable of finding truth.

    For more than two centuries, our understanding of the laws of nature expanded rapidly. But today, despite our best efforts, we know nothing more about these laws than we knew in the 1970s. Why is physics suddenly in trouble? And what can we do about it?One of the major problems, according to Smolin, is string theory: an ambitious attempt to formulate a “theory of everything” that explains all the particles and forces of nature and how the universe came to be. With its exotic new particles and parallel universes, string theory has captured the public’s imagination and seduced many physicists.But as Smolin reveals, there’s a deep flaw in the theory: no part of it has been tested, and no one knows how to test it. In fact, the theory appears to come in an infinite number of versions, meaning that no experiment will ever be able to prove it false. As a scientific theory, it fails. And because it has soaked up the lion’s share of funding, attracted some of the best minds, and effectively penalized young physicists for pursuing other avenues, it is dragging the rest of physics down with it.With clarity, passion, and authority, Smolin charts the rise and fall of string theory and takes a fascinating look at what will replace it. A group of young theorists has begun to develop exciting ideas that, unlike string theory, are testable. Smolin not only tells us who and what to watch for in the coming years, he offers novel solutions for seeking out and nurturing the best new talent—giving us a chance, at long last, of finding the next Einstein.

    Written by a 12th- century thinker who was equally active as an original philosopher and as a Biblical and Talmudic scholar, it is both a classic of great historical importance and a work of living significance today.The Guide for the Perplexed was written for scholars who were bewildered by the conflict between religion and the scientific and philosophic thought of the day. It is concerned, basically, with finding a concord between the religion of the Old Testament and its commentaries, and Aristotelian philosophy. After analyzing the ideas of the Old Testament by means of "homonyms," Maimonides examines other reconciliations of religion and philosophy (the Moslem rationalists) and then proposes his own resolution with contemporary Aristotelianism. The Guide for the Perplexed was at once recognized as a masterwork, and it strongly influenced Jewish, Christian, and Moslem thought of the Middle Ages. It is necessary reading for any full comprehension of the thought of such scholastics as Aquinas and Scotus, and indispensable for everyone interested in the Middle Ages, Judaism, medieval philosophy, or the larger problems which Maimonides discusses.

    In this volume, Karen Barad, theoretical physicist and feminist theorist, elaborates her theory of agential realism. Offering an account of the world as a whole rather than as composed of separate natural and social realms, agential realism is at once a new epistemology, ontology, and ethics. The starting point for Barad’s analysis is the philosophical framework of quantum physicist Niels Bohr. Barad extends and partially revises Bohr’s philosophical views in light of current scholarship in physics, science studies, and the philosophy of science as well as feminist, poststructuralist, and other critical social theories. In the process, she significantly reworks understandings of space, time, matter, causality, agency, subjectivity, and objectivity.In an agential realist account, the world is made of entanglements of “social” and “natural” agencies, where the distinction between the two emerges out of specific intra-actions. Intra-activity is an inexhaustible dynamism that configures and reconfigures relations of space-time-matter. In explaining intra-activity, Barad reveals questions about how nature and culture interact and change over time to be fundamentally misguided. And she reframes understanding of the nature of scientific and political practices and their “interrelationship.” Thus she pays particular attention to the responsible practice of science, and she emphasizes changes in the understanding of political practices, critically reworking Judith Butler’s influential theory of performativity. Finally, Barad uses agential realism to produce a new interpretation of quantum physics, demonstrating that agential realism is more than a means of reflecting on science; it can be used to actually do science.

    Examining heroic myths in the light of modern psychology, it considers not only the patterns and stages of mythology but also its relevance to our lives today--and to the life of any person seeking a fully realized existence.Myth, according to Campbell, is the projection of a culture's dreams onto a large screen; Campbell's book, like Star Wars, the film it helped inspire, is an exploration of the big-picture moments from the stage that is our world. It is a must-have resource for both experienced students of mythology and the explorer just beginning to approach myth as a source of knowledge.
