English Kaliedoscope Non Fiction 06: On Science Fiction

I have often made the point that true science fiction is a creature of the last two centuries. Science fiction cannot exist as a picture of the future unless, and until, people get the idea that it is science and technology that produce the future; that it is advances in science and technology (or, at the very least, changes in them) that are bound to make the future different from the present and the past, and that thereby hangs a tale.
