I must call to the reader's
attention the fact that this
book has little to say about
mechanisms in the brain that
have been or might be
uncovered by way of
explanation of perception.
Instead, I discuss, in
nonphysiological language,
theories of perception that
describe the kind of process
that might be assumed to occur
when we have various
perceptions. By analogy to
computers, one might say that
the first step in explaining
mental events is to describe
them in terms of the kind of
processing that occurs
(software) rather than in terms
of the neurophysiological
structures that can carry it out
(hardware). The reasons for
taking this approach are set
forth in Chapter 1.
