That's true, I still wouldn't be able to tell what green is or how you can recognize it. But that's not the point. The point is that this is an experiment that produces different results to me, with my limited senses, based on whether or not you have a sense of green.That doesn't prove that it's green.
It proves that I can pick that card from the rest and you cannot.
It doesn't make you see green either.
Based on your experiment, you would have to - on faith - take my word that the card is green.
So the question remains. Can you propose an experiment that would produce different results to me, with my limited senses, based on whether or not you have a sense that you're more than just a meatsack?
