Don; What you are describing is the difference between naive realism and representationalism, two basic philosophies on how we view the world. Discussion on this level gives me hope that the PDML can advance beyond the zoom vs.prime, digital vs. film, or dogs vs. cats discussions that usually occur.
<snip> We all know that colour doesn't exist outside the brain. This organ, over a long time, derived (evolved) a mechanism for distinguishing between different wavelengths of light. We call this colour perception. I don't think there is any way we can be sure that what one person sees is exactly the same as that seen by another. For example when we look at a particular shade of red - say a surface that reflects light in the region of 710 � - we can't be sure that Tom or Dick sees the same thing when he looks at the same Rose petal. His eye will distinguish the wavelength as a separate 'colour' but will it be the same as mine? Looking at a colour solid, or one of the Pantone charts, we see each patch as distinct from the others, but do we see the same thing and Harry standing next to us? May be. Maybe not. <snip> BUTCH "Each man had only one genuine vocation - to find the way to himself" Hermann Hesse (Demian)
