Abstract

One of the first envatted brains, the most cyborgian element of J. D. Bernal’s 1929 futuristic manifesto, The world, the flesh and the the devil, proposed a technological solution to the dreary certainty of mortality. In Bernal’s scenario the brain is maintained in an ‘out of body’ but ‘like-body’ environment—in a bath of cerebral–spinal fluid held at constant body temperature. In reality, acquiring prospective immortality requires access to very different technologies—those that allow human organs and tissues to be preserved in a quite ‘inhuman’ life-world—the cryogenic storage chamber. Like Bernal, today’s cryonicists consider that immortality can be secured through preservation of the brain alone. In this article I trace attempts to preserve or suspend life, and especially brain function, through the application of new ‘technologies of immortality’. Drawing together historical information on the development of refrigeration, cryopreservation, transplantation, and nanotechnologies, I explore the uneasy relationship between cryonics and the technology on which it depends for its success—cryogenics. In so doing, I argue that the ability to successfully realize the science fiction fantasy of human immortality will rest on a moral and scientific parasitism: the capacity to use the biotechnological artifacts or proxies—cryogenically preserved brains, archived brains, tissues, and immortalized cell lines—derived from the dead, in order to prolong life.
