  (Here is one way of putting the Inverted Earth version of this argument (see subsections 2.3.3 and 3.1). After first arriving on Inverted Earth, your word ‘red’ means red, and to you the green peppers on Inverted Earth look red. But after a period of acclimatization, you come to speak the language of the locals, and your experiences come to represent correctly the colors of things—green  peppers on Inverted Earth look green. Now compare your present experience of a green pepper on Inverted Earth with your previous experience of peppers of exactly that shade back on Earth. Same content, but different qualia. Alternatively, the anti-representationalist argument can proceed by exhibiting an example of the converse: same qualia, but different content—see Block 1990, 64–7.)
