Rumors have circulated for years about the strange contents of a huge unpublished work by Philip K. Dick. Here at last is the first publication of portions of the legendary Exegesis - selections from eight thousand pages written (mostly in longhand) during the last years of his life, when Dick was wrestling with a series of spiritual visions. In Pursuit of Valis contains autobiographical material, metaphysical diagrams, philosophical speculation and Dick's analysis of his own fiction.
