I've read some of Humphrey's books, but I don't recall that. What's his
Whats the citation?
His book "Seeing red" is based on lectures he gave at Harvard University
2004. What makes Humphrey´s theory special is that he thinks sensation is a
side show separated from perception. Dennett has also somewhat come around
to this view. He says in "It´s Not a Bug, It´s a Feature" in Journal of
Consciousness Studies 7 (2000): "Humphrey has convinced me that something
like his distinction between visual sensation and visual perception must be
Why would evolution create a side show and not just perception? What is it
for? asks Humphrey. He has been studying cases of blindsight and found that
although they have perception THEY DON´T CARE. The creation of a side show
is what having a sensation is, concludes Humphrey, and when sensation is
absent the subject thinks of him/herself as less of a Self.
Humphey thinks that sensation and perception from a common beginning take
relatively independent paths in evolution. Sensations in this view are
descendents of a kind of activity which once upon a time actually was a kind
of bodily expression but "nowadays is virtual, privatixed, adressed to an
as-if body; but there is every reason to suppose that its characteristics -
its dimensions - have remained in line with what they were". He further
notes that "the experience of creating a sensation has many of the
characteristics of creating a bodily expression".
