I suppose what you mean is something like: *** The information from the retina is inadequate to construct a representation of the world around the human organism that is as accurate as could be constructed by an ideal perceiving-system receiving the same light beams that the human eye receives. ***
But, so what? The human mind plainly does NOT have a world-representation of this level of accuracy. Our subjectively-perceived visual world is largely made up, as is convincingly demonstrated by our filled-in blind spots, the raft of optical illusions, and so forth.... We fill in the gaps left by our flawed visual systems using all sorts of inherited and learned inductive bias... -- Ben G On Sun, Oct 5, 2008 at 9:05 PM, Colin Hales <[EMAIL PROTECTED]>wrote: > OK.
