My point was that constants (or, more accurately, Skolem functions) are handled as an extreme case of the "tight existential quantification over a glorked domain", namely where the glorked domain is a singleton. Of course if this were the only relevant case, it would be perverse to consider it as quantification over a singleton domain. In other words: I'm converting your binary ambiguity - between the Skolem function "some things I (would) have in mind" and the existential quantifier ranging over the whole universe - into a vagueness, the glorked domain C interpolating between the two extremes. > Nor do I see the point of trying to bring together anaphora (typically > syntactic. occasionally semantic), deixis (always pragmatic, I think) > and the "whatever I have in mid" sense (probably pragmatic), as well > as the unfettered quantifiers of the indifferent gaps.

I don't know if it's a mistake. I don't see it as being much more conceptually repugnant that the binary ambiguity it interpolates, and it explains more uses. It is, however, incomplete as an explanation of unfilled places, because unfilled places are often more like generics - e.g. in "adjectival" predications like {ko'a se cinri} or {ko'a jdari}. > Careful about the order of thing; if resolution of {zo'e} comes after anaphora > (as it usually would, given your ideas), them {P(zo'e zo'e)} would not be the > same as {P(zo'e ri)} because each occurrence of {zo'e} is evaluated on its own. Yes, I think I was wrong to suggest that anaphora can be cleared up before interpreting the {zo'e}s and {lo}s. The real story is likely to be tricky. To take a simple example: when the {lo} is read generically, what does {lo remna cu prami ri} mean? There are two obvious possibilities - "humans love humans" (both generic) and "humans love themselves". The first is natural only if we admit kinds. (For nastier a example, consider the apparently classic {ro te cange poi ponse lo xasli cu darxi ri}... although I'd be happy simply considering this to be meaningless) > On Oct 9, 2011, at 13:03, Martin Bays <mbays@sdf.org> wrote: > > > * Sunday, 2011-10-09 at 12:11 -0400 - John E.
