The Seven Beauties of Science Fiction Quotes

“Unlike historical fiction (of which sf is a direct heir), where a less intense suspense operates because the outcome of the past is still in the process of being completed in the present’s partisan conflicts, sf is suspended because all the relevant information about the future is never available. Because future developments influence revisions of the past, sf’s black box also involves the past, in the hesitation that comes in anticipating the complete revision of origins.”
