Nor is quantum physics the only field in which Dick's speculations find a revelatory context. Consider the concept of "fake fakes," which is put to use in so many of Dick's novels and stories and which is explored persistently in his nonfiction writings as well. Examples included in the present volume may be found in the outline for a proposed (but never completed) novel Joe Protagoras Is Alive and Living on Earth, as well as in the proposal for a script (never written) for the television series Mission: Impossible and in the 1978 speech (likely never delivered) "How to Build a Universe That Doesn't Fall Apart Two Days Later." In essence, a "fake fake" is -- despite its seeming status as a mere contradiction that equates into "genuine" -- a radically new ontological category that takes on significance precisely because it perplexingly mimics (and even threatens to supersede) our "ordinary" or consensual reality. Hence the "fake fake" is no mere SF plot prop -- although Dick certainly employed it to dazzling effect as just such a prop -- but is also a commentary on the inundation of our world by mechanical and computer-generated simulacra.

In the field of art, Marcel Duchamp explored a similar range of ideas with his concept of the "readymade," a found object that Duchamp would ironically designate as a work of art, at times adding his own visual or linguistic touches (in which case the object became a "readymade aided"). In his 1961 essay "Apropos of 'Readymades,'" Duchamp broached paradoxes that serve to elucidate certain aesthetic possibilities of a world in which Dickian "fake fakes" proliferate. Wrote Duchamp:
