This book offers a social, political, and aesthetic critique of transhumanism and of the accelerating growth of scientific knowledge generally. Rather than improving our lives, science and technology today increasingly leave us debilitated and infantilized. It is time to restrain the runaway ambitions of technoscientific knowledge. The transhumanist goal of human enhancement encapsulates a range of dangerous social pathologies. Like transhumanism itself, these pathologies are rooted in, or in reaction to, the ethos of ‘more’. It’s a cultural love affair with excess, which is prompted by the libertarian standards of our cultural productions. But the attempt to live at the speed of an electron is destined for failure. In response, the author offers a naturalistic account of human flourishing where we attend to the natural rhythms of life. The interdisciplinary orientation of Transhumanism, Nature, and the Ends of Science makes it relevant to scholars and students across a wide range of disciplines, including social and political philosophy, philosophy of technology, science and technology studies, environmental studies, and public policy.
