Can the physicalist consistently hold that representational content is all there is to sensory experience and yet that two
perceivers could have inverted phenomenal spectra? Yes, if he holds that the phenomenal properties the inverts experience
are dummy properties, not instantiated in the physical objects being perceived nor in the perceivers’ experiences. In fact,
he should probably hold that phenomenal properties don’t exist at all. All there are, as far as phenomenal properties go,
are phenomenal property experiences.
