Working mostly alone, almost single-handedly writing 250,000 lines of computer code, Steve Grand produced Creatures®, a revolutionary computer game that allowed players to create living beings complete with brains, genes, and hormonal systems—creatures that would live and breathe and breed in real time on an ordinary desktop computer. Enormously successful, the game inevitably raises the question: What is artificial life? And in this book—a chance for the devoted fan and the simply curious onlooker to see the world from the perspective of an original philosopher-engineer and intellectual maverick—Steve Grand proposes an answer.

From the composition of the brains and bodies of artificial life forms to the philosophical guidelines and computational frameworks that define them, Creation plumbs the practical, social, and ethical aspects and implications of the state of the art. But more than that, the book gives readers access to the insights Grand acquired in writing Creatures—insights that yield a view of the world that is surprisingly antireductionist, antimaterialist, and (to a degree) antimechanistic, a view that sees matter, life, mind, and society as simply different levels of the same thing. Such a hierarchy, Grand suggests, can be mirrored by an equivalent one that exists inside a parallel universe called cyberspace.

The mind of the machine, the body suspended in time, organs exchanged, thought computed, genes manipulated, DNA samples abducted by aliens: the terrain between science and speculation, fraught with the possibility of technological and perhaps even evolutionary transformations, is the territory Richard Doyle explores in Wetwares. In a manner at once sober and playful, Doyle maps potentials for human transformation by new ecologies of information in the early twenty-first century. Wetwares ranges over recent research in artificial life, cloning, cryonics, computer science, organ transplantation, and alien abduction. Moving between actual technical practices, serious speculative technology, and science fiction, Doyle shows us emerging scientific paradigms where "life" becomes more a matter of information than of inner vitality-in short, becomes "wetwares" for DNA and computer networks. Viewing technologies of immortality-from cryonics to artificial life-as disciplines for welcoming a thoroughly other future, a future of neither capital, god, human, nor organism, the book offers tools for an evolutionary, transhuman mutation in the utterly unpredictable decades to come. Richard Doyle is associate professor of rhetoric and science studies in the Department of English at Penn State University. He is the author of On Beyond Living: Rhetorical Transformations of the Life Sciences (1997).
