" The spelunkers of speculative fiction mining phosphorescent filth from the bowels of the city of New Sodom, the Sci-Fi freaks scraping kipple and back from the bins of decades-old shit sandwiches out back, composting it to grow shrooms, we have built this thing to take its place.
This is the legacy of generations of writers who’d rather tackle adult themes than pander to puerile power-fantasies, whose interests lay with the soft sciences and humanities as much as with the hard sciences and technology, for whom the fiction was always more important than either the fantasia or the futurology. It is also the legacy of those who simply don’t give a fuck about anything other than either fantasia or futurology. This is fiction in which the envelope has been pushed so far out, from ambition or expedience, that all descriptions and definitions – SCIENCE FICTION, SCIENCE FANTASY, SCI-FI, even speculative fiction – can only be, at best, nominal labels for it. It is the fiction that abandons those labels for a negation of description, an indefinition – the acronym SF, which might mean any or all of those things. "
