Neuropsychedelia examines the revival of psychedelic science since the "Decade of the Brain." After the breakdown of this previously prospering area of psychopharmacology, and in the wake of clashes between counterculture and establishment in the late 1960s, a new generation of hallucinogen researchers used the hype around the neurosciences in the 1990s to bring psychedelics back into the mainstream of science and society. This book is based on anthropological fieldwork and philosophical reflections on life and work in two laboratories that have played key roles in this development: a human lab in Switzerland and an animal lab in California. It sheds light on the central transnational axis of the resurgence connecting American psychedelic culture with the home country of LSD. In the borderland of science and religion, Neuropsychedelia explores the tensions between the use of hallucinogens to model psychoses and to evoke spiritual experiences in laboratory settings. Its protagonists, including the anthropologist himself, struggle to find a place for the mystical under conditions of late-modern materialism.

How historical, social, and cultural forces shaped the psychedelic experience in midcentury America, from CIA experiments with LSD to Timothy Leary's Harvard Psilocybin Project. Are psychedelics invaluable therapeutic medicines, or dangerously unpredictable drugs that precipitate psychosis? Tools for spiritual communion or cognitive enhancers that spark innovation? Activators for one's private muse or part of a political movement? In the 1950s and 1960s, researchers studied psychedelics in all these incarnations, often arriving at contradictory results. In American Trip, Ido Hartogsohn examines how the psychedelic experience in midcentury America was shaped by historical, social, and cultural forces--by set (the mindset of the user) and setting (the environments in which the experience takes place).

Decades later, starting in the 1980s, Japanese cultural primatology was given a second look as Euro-American primatologists began to debate amongst themselves the question of whether Homo sapiens is the only cultural animal. In the most recent chapter of this controversy, field researchers such as the Swiss primatologist Christophe Boesch have accused experimental psychologists such as Michael Tomasello of underestimating and even denying the capacity of chimpanzees for culture because they limit their studies to captive animals, brought up under cognitively debilitating conditions and tested in laboratory settings bound to favor human test subjects with whom the animals are compared. These controversies raise serious questions about what sort of laboratory culture is best for the study of primate cognition. .

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.

We live in the digital age where our sense of self and identity has moved beyond the body to encompass hardware and software. Cyborgs, online representations in social media, avatars, and virtual reality extend our notion of what it means to be human. This approachable book looks at the progression of self from the biological to the technological using a multidisciplinary approach. It examines the notion of personhood from philosophical, psychological, neuroscience, robotics, and artificial intelligence perspectives, showing how the interface between bodies, brains, and technology can give rise to new forms of human identity. Jay Friedenberg present the content in an organized and easy-to-understand fashion to facilitate learning. A gifted researcher, author, and classroom teacher, he is one of the most influential voices in the field of artificial psychology.
