"Dick’s choice of the name Eldritch to (anti)christen his villainous cyborg signals, I think, a purposeful wedding of the textures and tones of SF with those of Gothic horror. A term redolent of Lovecraftian slime, “eldritch” designates the uncanny quality of even the most advanced technologies, their apocalyptic infestation of the soul. Yet for Dick the decay of human identity under the lurid gaze of dark gods is not a primordial regression, as Lovecraft would have depicted it, but rather the outcome of technological progress itself; the notion of the perceptual world as a manipulable construct, amenable to technoscientific control, unites Gnostic theology with psychedelic experience in a particularly science-fictional way."
