It's the natural extension of this abuse of notation: using
ce'u itself for the identity function.


But {ce'u} is not any function at all, and certainly not the identity function.  It is just a bound variable of a certain type, one that creates functions to types of objects out of those types of objects by putting in the holes.

But the value of the function will be different for each!
How is this different from the {le mamta be ce'u} case?
In both cases there is one function wich gives different values
for each of them as argument. They no doubt differ in
{le ka makau du ce'u}, in "who they are".>

Right you are, they do differ in le du be ce'u.  I got off on the fact that this is a pretty pointless one, since, if we know they differ at all, they differ in this way, so this is not very informative.  But itis true.  Thanks for reminding me.

Except where the matrix is the minimal sumti place itself? Why
can't ce'u stand for the identity function?>

The matrix here is a proposition, so {ce'u} in it creates a property.  To be sure, as you just pointed out, one of the arguments to this property that yields a truth is the identity function.  So, in that sense (application of function to argument) I suppose {ce'u} can stand for the identity function, along with several other functions, including {le du'u makau du ce'u}.  I don't see the thread of this argument at the moment, though, since that fact does not fit in with where I thought you were going or where you need to be going to make some sort of case here against {ce'u}in sentences or sumti.

<I don't think this is only about {djuno}. Is there any predicate
at all that will accept both {le broda} and {le du'u makau broda}
indifferently? >

I don't know, but I wouldn't be surprised  ({te tavla} looks like a case at first glance).  Again, what is the point here?  I thought your concern was about two abstractions, {le broda be ce'u} (a function to individuals) and {le du'u makau broda} (a set of propositions).  Why point to a concretum instead, {le broda}?  It seems irrelevant.

<You really don't see any parallel between the {le broda}:
{le du'u makau broda} pair and the {le broda be ce'u}:{le du'u
makau broda ce'u} one?

Sure, I see a parallel; the first are (very loosely) instances of the second, with the {ce'u} applied to the same argument ({zo'e}, I suppose).  So?  The fact remains that one of the first is a concretum, the other an abstractum, while both of the second pair are abstracts -- and it isthe role of abstracts that I claim allows them to function in the same environment.  So the problems (if there are any) with a concretum and an abstract in the same place have no bearing on the issue.

Yoou seem to be regularly confusing a function with its values and thatis likely to lead to a (n even more) serious mass of misunderstandings -- which it seems to have done.
