This expensive book ($108) is intended to serve a small, but dedicated group of scholars engaged in research on “transhumanism;” a subject that enjoyed popularity in the 1980s and 1990s. Transhumanists are optimistic futurists who welcome recent scientific and technological advancements in: “neuroscience, neuropharmacology, life-extension, nanotechnology, artificial ultraintelligence, and space habitation.” (p.1) Most transhumanists are also devoted fans of science fiction and/or spiritualism. Philosophers have long-argued that the very concept of transhumanism is vague or vacuous and that there has always been (and always will be) both defenders and critics of present and future technology. Critics of transhumanism argue that unchecked, free-wheeling scientific and/or technological advancement threatens not only the future of humanity, but also the future of the entire planet. Therefore, they argue, government must play a role in controlling that advancement: Keep that genie in the bottle! For better or worse, this scholarly work is rife with “isms” that are offered in comparison and contrast to “transhumanism,” including: neoliberalism, futurism, utopianism, post-humanism, evolutionary utopianism, and xenofeminism. With 200 pages of scholarly text, it is fully documented with over 600 footnotes, citing mostly of books and journal articles published in the 1980s and 1990s. By all measures, this is a book intended for a rather narrow community of scholars. There is no obvious attempt to recruit new transhumanist scholars, no appeal to a popular audience, nor is it intended to serve as an undergraduate or graduate textbook.
