Philip K. Dick, Ubik

The TV set had receded back a long way; he found himself confronted by a dark, wooden cabinet, Atwater-Kent tuned radio-frequency oldtime AM radio, complete with antenna and ground wires. God in heaven, he said to himself, appalled.
But why hadn't the Tv set reverted instead to formless metals and plastics? Those, after all, were its constituents; it had been constructed out of them, not out of an earlier radio. Perhaps this weirdly verified a discarded ancient philosophy, that of Plato's idea objects, the universals which, in each class, were real. The form TV set had been a template imposed as a successor to other templates, like the procession of frames in a movie sequence. Prior forms, he reflected, must carry on an invisible residual life in every object. The past is latent, is submerged, but still there, capable of rising to the surface once the later imprinting unfortunately --and against ordinary experience-- vanished. The man contains--not the boy-- but earlier men, he thought. History began a long time ago.
