Well, this was one of the subjects of the Lovecraft / Weird Fiction conference I was at on Thursday over at Goldsmiths. Amongst other things, we were trying to see if we could work out what distinguishes the weird from the uncanny / fantastic / marvellous. One formulation went like this. The (Freudian) uncanny is what seems supernatural, but really isn't - a trick of the light, a quiver on the surface of the natural. The marvellous is released from all constraints of naturalism. The fantastic the momentary equivocation between uncanny and the marvellous. The weird, on the other hand, is the addition to the natural of a novel truth - an enormity - which is then retroactively normalised. It *always was true* that Cthulhu sleeps in R'lyeh, but this truth is activated by being discovered (through a purely mundane process of investigation and "correlation" of natural fact). This is a bit like an *a priori* - discovered in the midst of experience, but discovered as a necessary ground for experience itself - except that instead of grounding experience, the weird enormity invalidates it: your entire sense of yourself and your place in the cosmos up until now turns out to have been a pathetic delusion. Compare the sequence in the classic alien abduction narrative where a hitherto unsuspecting (yet strangely troubled) person goes to a therapist and, under hypnosis, recovers repressed memories of being abducted by aliens. When confronted with the question of whether these memories are real or false (e.g. in some way "implanted" by the therapist who uncovered them, or confabulated during therapy), the subject acknowledges that the specific memories s/he has *might very well* be false, but nevertheless act as a screen / portal for the real, unrecoverable and unassimilable memory of having been abducted. Even though the "recovered memory" is a fake, its retroactive effect of truth is still in operation: from now on, that person's story is the story of an alien abductee, and the "fake memory" episode is just another episode in that story, itself a consequence to the original transcendental shock of abduction ("I invented these fake memories in order to protect myself from the mind-shattering terror of my real memories..."). I think that Lovecraft's fiction has this kind of structure: it produces a retroactive effect of truth, which outlasts the rather fanciful terms in which the originary horror is often projected ("Trauma will always linger", as Xasthur's Malefic has it).
