Philip K. Dick was both our most brilliant science fiction writer and a visionary philosopher who chose to couch his speculations in fiction. For, as he wrote about androids and virtual reality, schizophrenic prophets and amnesiac gods, Dick was also posing fundamental questions: What is reality? What is sanity? And what is human? This unprecedented collection of Dicks literary and philosophical writings acquaints us with the astonishing range and eloquence of his lifelong inquiry. The Shifting Realities of Philip K. Dick includes autobiography, critiques of science fiction, and dizzyingly provocative essays such as The Android and the Human and If You Find This World Bad, You Should See Some of the Others. Readers will also find two chapters of a proposed sequel to Dicks award-winning novel The Man in the High Castle and selections from the metaphysical Exegesis that inspired his classic VALIS. Witty, erudite, and exploding with intellectual shrapnel, this is the last testament of an American original. This collection confirms Dicks reputation as one of the foremost imaginative thinkers of the twentieth century.
