(You must have meant "extensional reading" up there.)
I find it objectionable as a translation of E1. I'm also not
quite sure how to interpret it. I would need first to understand
for example what it means for John to wear a blanket as, let's
say, Paul's coat. Does it make sense? Once I have understood
how it works with a definite case I can understand what L1
means, but if I can't grasp any definite cases, then it is
hard for me to understand L1. Maybe I should start with an
even easier case: "he wears his grey coat as his grey coat".
That seems obvious, if he is wearing his grey coat then he
is most likely wearing it as his grey coat and not as anything
else. Then from there go to "he wears the blanket as his grey
coat" (a coat he usually wears). That day he had sent the coat
to the cleaner's, so he replaces it with the blanket. So he
wears the blanket as his grey coat, ok. And then the difficult
jump to "he wears the blanket as Paul's coat" (a coat he never
wore, and maybe never even saw). How does he do that? I can't
make the jump. So if I can't make sense of that case, I find it
even harder to claim that there is an uspecified coat somewhere
such that he wears the blanket as that coat.

I mean the bridi in whose prenex their quantifiers are contained.
For a simple bridi, any {lo broda} filling one of the selbri's
standard places has an extensional reading in that bridi.

You mean something like {ko'a krici le du'u ge fo'a du fo'e gi
fo'a na du fo'e}? Yes, a person can believe contradictory things,
how is that a problem?

I don't really understand your point. I don't think we're disagreeing
about anything here anyway, except about the possible readings of
E1, and that is English, not Lojban. In the case at hand, {lo kosta}
is not within any du'u so none of those problems arise. There is no
such thing in Lojban, as far as I know, as an intensional place
that protects its arguments from exporting their quantifiers to
the prenex. {lo broda cu brode} is always {su'o da poi broda zo'u
da brode}, whatever brode is.

Any quantified term has to deal with the set over which the
quantifier runs. {lo broda cu brode} makes a statement about
the set of {broda}. It says that at least one of its members
is a brode.

No, with {lo'e broda} we don't deal with the set of broda
extensionally because we don't have a quantifier to run over
that set. It is pure intension. But this is not provided by
x3 of dasni, {lo'e} is intrinsically intensional, just as
{lo} and {le} are intrinsically extensional because they
have quantifiers to answer to. So in the same x3 of dasni, one
will produce the standard extensional reading, and the other
will produce a zi'o-type reading.

No there isn't. There is a word filling the x3 slot, but it's
a word like {zi'o} (only with greater semantic content).

{lo'e} marks those transcendental types which are not extensional.

We got away from the problem because we no longer have
quantification over coats at the main bridi level.
