On one occasion, Philip K. Dick (1928-1982) wrote, "The problem with introspection is that it has no end." On another, he said, "There is no route out of the maze. The maze shifts as you move through it, because it is alive." As readers will discover even more vividly this month, Dick followed his ruminations wherever they led. We live in debt to these instigations because they grapple with Big Questions about the nature of humanity, the backside of reality, the insights of insanity, and much more. In this book, twenty writers, many of them professional thinkers, grapple with Dick's ideas and what they mean for us. This paperback also contains the story on which The Adjustment Bureau is based.
