Samuel Delaney has stated that when the term ‘speculative fiction’ appeared in the Sixties, it was applied loosely to experimental fiction, often with imagery derived from science fiction and fantasy. Perhaps we’d label that ‘literary science fiction’ these days. But speculative fiction, as a name, varied some in its implications over the years (and pretty much disappeared for a while) before finding its current definition as the broad swath of genres stretching from science fiction to fantasy.
I do see it as such a spectrum. What all the genre and sub-genre within speculative fiction share is a self-standing alternate world, with its own internal rules and logic. That differentiates it from realistic fiction, which follows the rules of our own world, and the surrealistic, which bends those rules of the real world — with little regard for logic — to jar the reader’s perceptions.
‘Magic realism’ is, of course, a form of surrealism (by these definitions) rather than speculative fiction.
Rarely do I refer to any of my work as speculative fiction, though I legitimately could. It can sound pretentious, can’t it? My science fiction is readily identified as such. The fantasy — despite most having rather strict science fiction-like underlying rules — would be regarded as fantasy by most. Those terms are good enough for me.
By the way, horror is sometimes included as a sort of speculative fiction but I don’t consider it a genre at all. I would call it a theme, that can be applied to almost any genre. Monsters are everywhere!
