| Aug 21, 2018 at 0:07 | comment | added | Conifold | @rus9384 McGinn does not assume physicalism, and indeed argues for its implausibility, so such an assumption begs the question. And physicalist's position is not that "humans perceive colors in similar ways" in the relevant sense of "what it feels like", it is that asking if something feels different or the same to different subjects is a meaningless question that twists the language. | |

Further science shoild investigate if neurons connected to them are similar. If so, assuming physicalism we are done: humans perceive colors in similar ways. However, given that different colors also have different secondary effects (grey sky makes people more sad, for example) it is already plausible these experiences are similar for all people (I don't assume blind and colorblind). | |

| Aug 20, 2018 at 21:17 | comment | added | Conifold | McGinn overreaches with his rhetoric, but the core of his argument refers to "what these states feel like to you" as to what is unknowable. It does seem plausible that we can find physical correlates to say "manic" but on reflection these correlates correlate neural patterns to overt behavior, not to "what it feels like". Indeed, since we have no access to "what it feels like" other than, well, feeling it, and the feeling can only be done in the first person, it is by design impossible to correlate it to anything physical. We know not if what we both call "red" "feels the same" to both of us. | |
