ABSTRACT
This chapter aims to construct systematic and unitary analogs of all ten arguments, analogs that support a parallel family of antireductive conclusions about the nature of light. The ontologically distinct nature of light is further reflected in the fact that the distinction between appearance and reality, which holds for any broadly physical phenomenon, cannot be drawn in the case of light itself. The conceivability of a dark universe filled with electromagnetism (EM) waves shows only that the various cross-theoretic identities motivated by the EM reduction are, as they should be, contingent rather than necessary identities. It should be pointed out that such an "open question" argument will be maximally appealing to one who is minimally instructed in EM theory. EM theory successfully reduces objective spectral colors to different wavelengths of EM radiation, but leaves their subjective conscious effects on humans aside.
