I think explanations are important to prove causation ;-) and it's interesting that you can break this example down. Each explanatory step is materially plausible (it has a satisfactory public explanation), right up to the perception of the light. But the qualia (qualium?) itself doesn't have a public description, and there isn't any sense of satisfaction that it has been explained. It's tempting to believe that's because it's a complicated step, but there seems no obvious way to reduce it. So as far as I can see it is still only an assumption, with the hope/faith that some plausible explanation will one day be found. I'm not sure there are many other widely-held scientific explanations like this one? > > > you remove any connection between neurons, yet the words of one brain >> (or brain activity ostensibly associated with the words) are still >> transmitted from one to the other. >> > > When you write books I don't always read them AND if I don't read your > book your book still exists, so I can say with great confidence that my > reading of your books does not cause your books to exist. > > John K Clark > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
