Presenting acclaimed essays from one of contemporary science fiction's most imaginative wordsmiths, this collection shows that Robert Silverberg's non-fiction is as witty and original as his fiction and full of acute observations and matter-of-fact insights. Whether he is discussing science fiction, history, cultural effects, science, or writing, Silverberg is always exploring new territories. As in his fiction, no cultural icon escapes his scrutiny, including fellow writers such as Robert Heinlein, Arthur C. Clarke, H P Lovecraft, and Isaac Asimov. Delightfully wicked commentaries on the concepts of thought crimes, space exploration, the ancient Antikythera Computer, and the universal translator in science fiction fill these essays, many of which were originally published as columns in Asimov Science Fiction magazine.
