An exploration of the emergence of a new psychedelic spirituality in the work of Philip K. Dick, Terence McKenna, and Robert Anton Wilson. A study of the spiritual provocations to be found in the work of Philip K. Dick, Terence McKenna, and Robert Anton Wilson, High Weirdness charts the emergence of a new psychedelic spirituality that arose from the American counterculture of the 1970s. These three authors changed the way millions of readers thought, dreamed, and experienced reality-but how did their writings reflect, as well as shape, the seismic cultural shifts taking place in America? In High Weirdness, Erik Davis-America's leading scholar of high strangeness-examines the published and unpublished writings of these vital, iconoclastic thinkers, as well as their own life-changing mystical experiences. Davis explores the complex lattice of the strange that flowed through America's West Coast at a time of radical technological, political, and social upheaval to present a new theory of the weird as a viable mode for a renewed engagement with reality.
