I suspect the real breakthroughs in our understanding of consciousness are going to come from an entirely different direction. That direction, controversially, has to do with psychedelics-which, as many of the contributors to The Divine Spark argue, offer spectacular potential for the investigation of the 'hard problem' of consciousness. -from the introduction by Graham Hancock Psychedelics: Medicinal? Vital in interspecies communication or communion with the sacred? Helpful for reaching enlightenment or damaging to the brain? In this anthology, edited by bestselling author Graham Hancock, twenty-two writers illuminate the topic of psychedelics and consciousness like never before. Travel to South America, the American Southwest, outer space, inner space, and back in time to revisit Pahnke's The Good Friday experiment. Explore the effects of ayahuasca, LSD, and much more. The contributors to this volume are Mike Alivernia, Russell Brand, David Jay Brown, Paul Devereux, Rick Doblin, Ede Frecska, Alex Grey, Nassim Haramein, Martina Hoffmann, Don Lattin, Luis Eduardo Luna, Dennis McKenna, Thad McKraken, Rak Razam, Gabriel Roberts, Thomas B. Roberts, Gregory Sams, Robert M. Schoch, Mark Seelig, Rick Strassman, Robert Tindall, and, of course, Graham Hancock.
