Book excerpt: Essays in this volume demonstrate how science fiction can serve as a bridge between the sciences and the humanities. The essays show how early writers like Dante and Mary Shelley revealed a gradual shift toward a genuine understanding of science; how H.G. Wells first showed the possibilities of combining scientific and humanistic perspectives; how writers influenced by Gernsback's ideas, like Isaac Asimov, illustrated the ways that literature could interact with science and assist in its progress; and how more recent writers offer critiques of science and its practitioners.
