No, it's absolutely correct. You said "once I show a single SF work with a certain characteristic, that characteristic exists within the set of all SF." That's utter nonsense if you're asserting it has anything to do with a definition of SF, which is the entire point of this thread. What is F? What is SF? The answer isn't 'well here's a diagram of every work of F or SF ever written, and F and SF are everything included in these works.' Before you can even draw your diagram, you need a way of deciding what is and is not SF in the first place, which the all-in approach is decidedly incapable of giving you. So the question remains: how do you decide?Dannyalcatraz said:Absolutely incorrect.
If you really believe what you said however many pages back ("There are portions of each circle that do not touch any other. In other words, you can have pure Fantasy"), then why are you talking about all-inclusive sets? The point of defining SF and F is to locate the portion of the circle that does not touch the others, so again, it seems to me you're muddying the issue by fore-deciding what SF is, then saying everything that is part of every work of SF is part of SF. What is SF in the space where F and Horror and whatever else are not present? Which was my point when I said: a definition of SF contains only what is essential to all SF (and not everything that has ever been included in every remotely SF story ever but which is in no way obligated to be a component of any SF story at all).
I don't know whether you're quibbling over semantics or just dancing around the issue. I've already said that all writing is mixed, meaning SF can have elements of other genres. You're saying no, all writing is homogenous, and everything that is part of every SF work is part of SF, only inessential to it, so unusable as far as defining SF goes. So you agree that squirrels are inessential to defining SF, lovely--what the hell was the point of talking about sets and inessential qualities then? Just to say that, in your opinion, everything that's part of a SF work is SF, though not essentially, whereas in my opinion much of a particular work of SF may belong essentially to another genre, which is in that work mixed with SF, and the only thing that is SF is what is essentially SF?Dannyalcatraz said:Something can be within SF but not be an essential quality of it. If it is not essential, then it cannot be used to define the limits of the genre. The fact that I can find (as you say) squirrels in SF just means that there are squirrels within SF- once I find squirrels in other, non-SF fiction, I know that squirrels are not an essential quality of SF.
A sword is nothing whatever--it's a prop. A genre can make the sword its centerpiece and be definable in terms of the sword, but then we aren't even talking about the sword anymore: we're talking about its iconography, or its uses, what it does or could do, who it belongs to, what it represents. The sword in itself, as mythusmage was saying, is mere staging. It could just as well be a broom or a chainsaw. This is surface stuff.Dannyalcatraz said:Instead of squirrels (is there something going on on the boards with all this talk of squirrels?), a better example might be swords. Swords show up in all kinds of fiction: SF, Fantasy, Civil War fiction, Japanese modern and imperial-period historical fiction. Swords can thus be said to be part of any of those genres, but they don't even begin to define any of them. Including the presence of swords as part of the definition of Fantasy (or any other genre) doesn't help because it allows the inclusion of things that are not part of that genre- it is insufficiently exclusive.
Why is this the point? Nobody's claimed, as far as I've seen anyway, that the difference between a dog and a wolf is what they have in common. I thought we covered this when you said "By defining something as a genre, then, you are taking for granted that it is unique," to which I responded "Yes, I am, otherwise it's undefinable: for every class α1 and definition β, if α1 is β then α2 is not β ( (α1) [βα1 → ~βα2] ), otherwise α1 and α2 are the same thing, i.e. there is no α2." In other words if chair and cushion have the same definition then there is no difference between a chair and a cushion; in order for there to be two different classes of object, chair and cushion, their definitions must differ somewhere; as totalities their relation to one another is one of difference. At what level this uniqueness emerges is unimportant; it's simply a tautological fact that if there are two different classes, the two classes are different.Dannyalcatraz said:THAT is the point of my discussion of taxonomy: to illustrate that its the differences, not similarities, that define species as apart from other species.
Are you just deferring the debate from "genre" to "characteristic?" Honestly, at the biological level we're all made from the same components, and our differences emerge farther up, that's a bit duh. Genre and biology aren't the same thing, unless you're sticking to imagery, in which case maybe the comparison highlights the ridiculousness of that approach. In terms of content, not all writing is made from the same stuff; meaning always emerges uniquely, and doesn't necessarily have anything in common with any other writing at any level, really. There've been a few movements that claimed otherwise, like structuralism, but those always died out rather quickly for a reason.Dannyalcatraz said:Analogously, we can't say that "X" is a defining characteristic of SF if "X" is not unique SF.
