The Exegesis of Philip K. Dick is the landmark 2011 publication of Dick's vast private philosophical journal by Houghton Mifflin Harcourt, edited by Pamela Jackson and Jonathan Lethem with Erik Davis as annotations editor. Copyright is held jointly by Laura Coelho, Christopher Dick, and Isa Hackett (Dick's heirs).
The volume is organized in four parts, with an introduction by the editors, an afterword by Richard Doyle titled "A Stairway to Eleusis: PKD, Perennial Philosopher," extensive endnotes, a glossary, and separate indexes for names and works. The Library of Congress description characterizes it as Dick's "magnificent and imaginative final work" dedicated to questioning the nature of reality and perception.
Preserved in typed and handwritten notes, journal entries, letters, and story sketches, the Exegesis represents Dick's sustained philosophical investigation following his mystical experiences of February-March 1974. This published edition, while representing only a fraction of the estimated 8,000 pages Dick wrote, superseded the earlier Sutin-edited In Pursuit of VALIS as the definitive published source for Dick's metaphysical writings. It stands as one of the most extraordinary documents in American letters, combining rigorous philosophical inquiry with deeply personal spiritual searching.
