If I don't know what I'm referring to when I say "consciousness," it seems reasonable to conclude that I ought not use the term.
What it is, to know what one is referring to? If I see a flying saucer, I may be wrong in believing it's an alien spaceship, but I am not wrong about seeing something, a thing I also believe to be an alien spaceship.
pangel says:
The fuzziest starting point for "consciousness" is "something similar to what I experience when I consider my own mind".
and that is the brute fact from which the conundrum of consciousness starts. The fact of having subjective experience is the primary subject matter. That we have no idea how, given everythin...
This seems significant:
