“Valid descriptions” don’t account for why things are this way rather than some other way.

Wild speculation. As I said before, materialism could conceivably explain human ability and behavior, but in my opinion runs aground at human consciousness. Therefore, I doubt that humans are a complex sort of robot. > Humans have intentionality. Granted. I do anyway. So at least one human does. > Therefore some other, sufficiently complex, robots have intentionality Not proven. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
