Paul,
 From my point of view, I'd have to point out that this appears to be
an example of either not distinguishing between the mental constructs
we form to explain experience and whatever it is we imagine gives
rise to that experience or a case of making without stating it the
assumption of realism. The article I pointed to indicates that there
are other options we should consider.

"As a result of modern research in physics, the ambition and hope, still cherished by most authorities of the last century, that physical science could offer a photographic picture and true image of reality had to be abandoned." --M. Jammer in Concepts of Force, 1957.

"If what we regard as real depends on our theory, how can we make reality the basis of our philosophy? ...But we cannot distinguish what is real about the universe without a theory...it makes no sense to ask if it corresponds to reality, because we do not know what reality is independent of a theory."--S. Hawking in Black Holes and Baby Universes, 1993.
