Doesn't Dawn mean here "exogenous to the _control_ system", not referring
loosely to the behaving organism as "the system"?
Even if that is the case, she still has a problem. Throughout most of B:CP,
Bill does show the reference signal coming in from the next higher control
system, to be sure, and hence exogenous to the CS under discussion.
But, in the final analysis, on p. 217 in the chapter on Memory, he says,
"One change in the model covers all cases, including many we have not yet
considered. The change is this: We will assume from now on that _all_
_reference_ _signals_ _are_ _retrieved_ _recordings_ _of_ _past_
_perceptual_ _signals_ [emphasis in original]. This requires giving the
outputs from higher-order systems the function of address signals, whereas
formerly they were reference signals. The address signals select from
lower-order memory those past values of perceptual signals that are to be
recreated in present time."
Hence reference signals are _always_ endogenous, not only to the organism
but also to the control system.

On page 162, as part of her review of what she calls "perception control
theory," she indicates that "The reference signal itself is exogenous to the
system." I don't understand that. I thought reference signals were part of
the behaving person and thus endogenous. Oh well, it's probably just the
case that I don't understand big, fancy words.
