Valis is a 1981 science fiction novel by American writer Philip K. Dick, intended to be the first book of a three-part series. The title is an acronym for Vast Active Living Intelligence System, Dick's gnostic vision of God. Set in California during the 1970s, the book features heavy auto-biographical elements and draws inspiration from Dick's own investigations into his unexplained religious experiences over the previous decade.
