However, when you look at red, you experience what I experience when I look at blue. Because the experiences are systematically swapped, you consistently refer to blue as blue, and red as red. Now comes the experiment. How would you demonstrate empirically that your red and blue experiences are different, as opposed to us both having the same color experience when we look at the same color, red or blue. How can you empirically demonstrate one case, experiences swapped, versus the other, both sets of color experiences the same?
If you mean in the absolute sense, I can't. Nobody can. But empiricism is not supposed to be based on absolutes but rather on what's more likely based on the evidence available.
