It wasn't intended for this purpose, but merely to illustrate (once
again) the very "shoot from the hip" approach that Schiller has
taken.

Quite a leap indeed.  I am more than a little bit uncomfortable in
appearing to defend the "theory-ladeness of perception" type of thesis
advanced by Campbell, Feyerabend, et al.  I don't buy it, of course.
And one needn't (as you realize) defend this extreme view in pointing
out the inadequacies of Schiller's position.

No, but having been a professional philosopher I *did* read Rand's
essays (carefully, I might add).  Since Schiller claimed to be a
"scientist", it seems to me likewise that he *ought* to be familiar
with at least *some* of this (it is hardly the property of philosophers,
and I believe that anyone educated as a genuine scientist must of
necessity have encountered *some* of the issues and arguments).
Quite honestly, at this point it appears to me that Schiller's view
of theories and their role in science (as well as his knowledge
of the history of science) is so naive that I suspect the claim to
being a scientist.  Suppose in response to the naive operationalist
view of Schiller (I won't even call it 'instrumentalist' any more),
I were to raise to *you* the simple question, "If such statements
as we have been considering are *only* shorthand descriptions of
our past experiences, what about the status of nomological
generalizations?"  I believe *you* would know what I meant and
could at least state the problems.
