Written by the pioneering scientist, theorist and activist J. D. Bernal, this futuristic essay explores the radical changes to human bodies and intelligence that science may bring about, and suggests the impact of these developments on society. Bernal presents a far-reaching vision of the future that encompasses space research and colonization, material sciences, genetic engineering, and the technological hive mind. In his view, it will be possible for the conditions of civilization to reach a state of materialist utopia. For all three realms—the world, the flesh, and the devil—Bernal attempted to map out the utmost limit of technoscientific progress, and found that there are almost no limits.

With a new introduction by McKenzie Wark.
