If the scenario can be filled out such that the two experiences have the same representational content and the scenario is metaphysically possible, then representationalism predicts identical qualia — contradicting the stipulated difference.
Something that could exist or happen in reality without violating the fundamental laws of nature — not logically contradictory.
qualia(The passage presents two competing definitions to contrast the views)
On the Cartesian picture: intrinsic qualities of inner ideas of which subjects are directly aware, necessarily shared by internal duplicates regardless of environment. On wide representationalism: representational contents of inner states whose nature is partly externally determined
scenario(as used in philosophical arguments)
A detailed imagined situation or setup designed to test a philosophical idea, like a thought experiment.
Spectrum inversion scenarios help to focus the dispute between representationalists and their critics. (Actual cases of shifted spectra can also serve: see Block 1999.) Any version of representationalism is committed to the following thesis. Consider a case of red-green spectrum inversion, and imagine Invert and Nonvert are both looking at the red peppers depicted in figure 6, against a neutral background. Nonvert’s experience has \(Q_{R}\), while Invert’s experience has \(Q_{G}\). Because the t
