In Ubik, first published in 1969, we find the first distinct appearance of the transcendental element in Dick's work. In his earlier novels, he had been content to demonstrate that there is no "objective" reality irrespective of consciousness: the mind essentially constructs its own world. In Ubik, the protagonist Joe Chip, condemned to a perpetual "half-life" of suspended animation after a fatal accident, finds his world inexorably deteriorating around him. The only thing standing between Joe and complete extinction is a product called Ubik, which comes in spray cans, and, when sprayed on, instantly counteracts the forces of destruction. Among other things, Ubik appears as a razor blade, a deodorant, a bra, a breakfast cereal, a pill for stomach relief, plastic wrap, a salad dressing, a used car, and a savings and loan. As its name implies, it is ubiquitous. Though a symbol of the divine, it is not a mere magical aid but a gift that can only be summoned by the person who needs it through an exercise of will and intelligence. The ending of Ubik has a twist that calls into question the substantiality of the "real world." This is my favorite PKD novel, the one that combines the most dazzling metaphysics with the most involving story and characters. After reading it, one can only start scanning one's own environment for hopeful signs of the redeeming Ubik!
