Perhaps it’s simply my lack of experience with philosophy, but I fail to see any qualitative distinction between common perceptual failures like optical illusions, versus those examples given by lukeprog in the OP. I’m sure lukeprog is setting this up to do some work in one of his later posts in the series. But at this point given no particular reason to draw a boundary anywhere except at the tautology, I draw it at the tautology.
