In what N. Katherine Hayles describes as this enormously ambitious posthumous volume, renowned scholar George Slusser offers a definitive version of the argument about the history of science fiction that he developed throughout his career: that several important ideas and texts, routinely overlooked in other critical studies, made significant contributions to the creation of modern science fiction as it developed into a truly global literature. He explores how key thinkers like Rene Descartes, Benjamin Constant, Thomas De Quincey, Guy du Maupassant, J.D. Bernal, and Ralph Waldo Emerson influenced and are reflected in twentieth-century science fiction stories from the United States, Great Britain, France, Germany, Poland, and Russia. The conclusion begins with Slusser’s overview of global science fiction in the twenty-first century and discusses recent developments in countries like China, Romania, and Israel. Hayles’s foreword provides a useful summation of the book’s contents, while science fiction writer Gregory Benford contributes an afterword providing a personal perspective on the life and thoughts of his longtime friend. The book was edited by Slusser’s former colleague Gary Westfahl, a distinguished scholar in his own right.
