Re: [lojban] {zo'e} as close-scope existentially quantified plural variable



I'm not clear where these circumstances came from; the original is just about 
money.  To be sure, your giving me money is a circumstance, as is my buying 
drugs with it, but why go into that.
The context leaper rule (verso existential with anaphora outside its scope is a 
recto universal with scope covering both cases) is nothing to do with logic per 
se but is about getting things into regimented form.  And that, as Montague 
would say, is just a fact of the grammar of English, properly understood.  Does 
it really work for Lojban?  Donnow, let's work it out.  since Lojban is 
*supposed* to be regimented already, the problem shouldn't arise.  But it seems 
to, so either Lojban is not regimented (and so needs some work) or some forms 
that we have been using are improper or don't mean what we think they do.

Why does it have the wrong meaning? Is it still wrong if you use "any"
instead of "all"? I think my solution would give: "For any money, if
you give it to me, I'll spend it on drugs" or "I'll spend on drugs any
money you give me".

I think the issue with donkey sentences is not so much reformulating
them in terms of ordinary first order logic, which can be done by
replacing the short scope existential by a wide scope universal. The
problematic issue is explaining what's going on, since this conversion
is not licensed by any rules of logic.
