It is argued that theoretical models cannot use qualia as explanatory
tools, and cannot explain them either; thus, there is no way to make q
ualia do any useful work at all, at least in a theory. However, qualia
do occur in both imagery and perception, and this article presents so
me ways of thinking about qualia from a functional perspective. Imager
y differs from perception in its function. It is not a faded copy of p
erception. It is less distinct than perception because it is only as d
istinct as it needs to be, not because it is inherently indistinct. Qu
alia represent functionally relevant encodings whether in perception o
r imagery. The present approach is functionalist and quite similar to
Pani's (1996). (C) 1996 Academic Press, Inc.
