Philip K. Dick

Philip Kindred Dick was an American novelist, short story writer, and essayist whose published work during his lifetime was almost entirely in the science fiction genre. Dick explored sociological, political and metaphysical themes in novels dominated by monopolistic corporations, authoritarian governments, and altered states. In his later works, Dick's thematic focus strongly reflected his personal interest in metaphysics and theology. He often drew upon his own life experiences and addressed the nature of drug abuse, paranoia and schizophrenia, and transcendental experiences in novels such as A Scanner Darkly and VALIS.
