>because organisms wouldn't survive if their entire perceptual system produced only illusions. Small correction. You should say "organisms wouldn't survive if their entire perceptual system produced only useless illusions." The illusions here can also be replaced by an "abstraction". Color is an abstraction of wavelength. Sound is an abstraction of pressure differences. So organisms who's senses produced useful abstractions for their minds prevailed, while others perished. So again, obviously, I see nothing new but the premise that useless abstractions evolved but didn't sustain...
