In this highly original book, Russell Blackford discusses the intersection of science fiction and humanity's moral imagination. With the rise of science and technology in the 19th century, and our continually improving understanding of the cosmos, writers and thinkers soon began to imagine futures greatly different from the present. Science fiction was born out of the realization that future technoscientific advances could dramatically change the world. Along with the developments described in modern science fiction - space societies, conscious machines, and upgraded human bodies, to name but a few - comes a new set of ethical challenges and new forms of ethics. Blackford identifies these issues and their reflection in science fiction. His fascinating book will appeal to anyone with an interest in philosophy or science fiction, or in how they interact.
