But it’s not the case, as implied, that the notion of consciousness involves a soul or some such thing, nor is the idea of consciousness (necessarily) related to “magical” stuff. It doesn’t follow from viewing us as mere machines whose free will is an illusion that consciousness too is an illusion. It’s been said before, correctly, that the only thing we can be certain of is our own consciousness.
Talking of Occam’s razor: Assuming that other humans are as real as I am, and that they are as conscious as I am, seems a far simpler conception of reality than assuming that I am some sort of Boltzmann brain imagining it all.
Perhaps defining consciousness would have clarified the article’s proposition. It seems that consciousness is being equated with our ability to introspect, to think about us thinking, i.e., with our self-awareness; but feeling pain and pleasure, for instance, is part of our subjective experience too, and as such considered part of consciousness. Is pain an illusion?
