I assure you that I am not doing it on purpose. >But the cases we were discussing were -- I thought -- about getting one >token >of a type out of a set of such tokens -- each of them being in fact an >event >type. Getting tokens out is done with le/lo. I don't think we disagree there. {ro lo broda} gets each token from {lo'i broda}, {ro lo nu broda} gets each token from {lo'i nu broda}. >That still seems to me to be inherently extensional for all that the >extension is made up of intensional objects. Indeed, le/lo are always extensional. On the other hand: {lo'e broda} gets the type from {lo'i broda} and {lo'e nu broda} gets the type from {lo'i nu broda}. For any given set, there is one type. (Of course there are sub-types to go with the respective sub-sets.) >Maybe we >need to set up some terminology so that the various sorts of intensions are >sorted out.

The way I understand it, fronting, quantifier binding, etc don't apply when you _use_ an intension. When you _talk about_ it, you tokenize it. {le ka ce'u broda} is used to talk about the intension. The intension is in this case a token. With {lo'e broda} I make use of the intension, I don't refer to the intension. >Let's keep >"intension" as a general term for objects which are referred to by >expressions with those properties. Ok. We can say that {broda} is always intensional. But {lo broda} and {lo ka broda} are always extensional (one referring to broda-tokens and the other to ka-tokens). {lo'e broda} is the way I found to keep the intensionality of the broda-type at sumti level. {lo ka broda} maintains the intensionality of {broda}, (it is extensional for ka) but it is the wrong kind of object when we have a place that requires broda-tokens or broda-types. >Types and tokens are another matter entirely, though perhaps practically >related.

And how do you make use of that type? (I don't mean talk about it, but make use of it.) >The two share some properties and these are defining for the >type -- and they typically "have" them in different ways, though the >terminology here is muddier than usual: the token typically is subject of >the >property, the type contains the property (to take what seems to me the >least >confusing pair of possibilities). Yes, you are _talking about_ the type. I'd like to see some uses. >The quasiness of the intensionality comes >about from the fact that some real-world truths affect the issue of what >tokens may fall under a given type: the fact that Jill is Jack's bitchy >sister means that the proposition that Jack's bitchy sister is asleep falls >under the same type as the proposition that Jill is asleep, even though >they >are not the same proposition.

I suppose that the sense of >that >predicate expression is pretty close to just that, the property of falling >under that proximate type. Ok, as I said before, I am not very clear about the sense of the predicate headed by {du'u}. My instinct says that {lo'i du'u ...} has only one member, and in one-member sets making the type-token distinction is probably hair-splitting. But if {lo'i du'u ...} has many members then {du'u} should behave like any other {broda}. >Why not, in complete generality, use {le du'u ce'u broda} in this case >(assuming that this refers to the sense corresponding to the reference lo'i >broda, i.e., the sense of {broda}, which it ought do)? That is how I would refer to the intension, yes. (I would use {ka} rather than {du'u}, but that's beside the point.) I use {lo'e} not to refer to intensions but to make use of them: ta simlu le ka ce'u sfofa That appears to have the property of being a sofa. ta simsa lo'e sfofa That is like a sofa. I can't use {le ka ce'u sfofa} with {simsa}, because {simsa} compares same level objects, not objects with properties. I can use {le ka ce'u sfofa} with {simlu} because {simlu} is an object-property relationship. >I suppose that >"when I don't want to quantify over the extesion of the set" means "when I >want to talk about the sense of the expression delimiting to the set rather >than to the set itself or its members" It means "when I want to use the sense", not "talk about the sense". mu'o mi'e xorxes _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com ------------------------ Yahoo!
