[From Fred Nickols (990505.1720 EDT)]-- Came across the following on another list (the learning organization or LO list) and immediately thought to solicit reactions from CSG Netters... Critique, anyone? If I recall, no one on this list was particularly impressed by Pinker's book and it might or might not be a good "lay reference." >Leo writes: > >>What I am going to say here, may make the confusion even larger, or it >>may help Steve and others to narrow the gap between the 'real' world with >>the world of imagination. > >>The whole world around us is a world of imagination. It is a translation >>of the signals of our body-sensors into a picture in our mind. If we see >>a house, this picture of the house is caused by the electromagnetic >>photons from a source via our eyes into our brains. The brains create in >>the mind a picture of the source.

This is fine, but the PCT term is "perception," not "imagination." What we mean by imagination is a signal in the perceptual channels that is manufactured inside the brain instead of being caused by photons. I think the author needs to think this through some more. For example, how does his brain know about photons? Best, Bill P.
