I think of science fiction, including my own, as very much a paraliterary genre. The fact that it lives – and has lived – on the margin is important to its history. If you remove it from that margin, you remove it from its historical context; I don’t think that’s such a good thing. Genre boundaries are real power boundaries. Bringing all the genres together into what, following Roland Barthes, Susan Sontag called “the great democracy of texts” has endless problems – quite as many as trying to mete equality out among classes, races, and religions. “Let’s get al the races together and we’ll have no problems” – starting tomorrow.
