OK then. I'll reiterate, with all the clarity I can muster.

Short version: {su'o cinfo cu broda} has to mean that some actual lion
brodas. Otherwise we have problems. This is largely independent of the
meaning of {lo cinfo cu broda}, but not of the explanation of that
meaning.

Long version:

The basic problem as I'm seeing it: if we don't specify levels, then we
don't really specify quantifier scope.

What I mean by this (i.e. by "really"): if B hears A say {su'o ctuca cu
tavla ro le tadni}, and B wants to understand what A means to say about
actual teachers and actual students, and if {ctuca} and {tadni} do not
specify levels, then B has to guess which levels A intends them to refer
to. If, for example, B guesses that A is talking about kinds of teacher
and about actual students, all B can deduce about actual teachers and
students is that every student was talked to by some teacher.

(Here I'm using 'actual' in opposition to 'kind' - I wish we had
a better word for it)

(I should also clarify that when I say "{ctuca} does not specify
a level", I mean that there are *individuals* which are e.g. kinds of
teachers and which ctuca; if a kind were implemented as being merely
a bunch of actual teachers, we wouldn't have the problems I'm talking
about.)

So I conclude that it is not befitting of a logical language for it to
have no means to specify level - where 'level' refers to whatever it is
that crossing causes these quantifier scope shifts.

This does not mean that I think lojban should only be able to discuss
actual teachers and not kinds of teachers - merely that we need to be
able to distinguish between the two.

I further note that xorlo - or rather, my understanding of xorxes'
understanding of xorlo - makes this issue less academic than it might
otherwise be. That's because it has descriptions, e.g. {lo ctuca},
habitually (though not always) referring to (bunches of) corresponding
kinds, e.g. to the kind Teacher.

So under xorxes' xorlo, kinds are not rare things summoned up only when
we specifically want to talk about them - you have to deal with them if
you want to understand any sentence using a gadri.

(Here I'm using "the kind Teacher" to refer to the whatever-it-is that
xorxes habitually refers to with {lo ctuca}; I have so far failed to
understand what this is, but it seems that whatever it is is a level up
from actual teachers as regards quantifier scope ambiguities, and that's
all we need to know about it for the present discussion)


This leaves the question of how to deal with this problem; we have
various partial answers, but perhaps I shouldn't complicate this thread
by discussing them here.
