> "Consciousness" means "an existing stream of experiences". Those seem equally nebulous. > "Free will" means "a feeling that one could've made a different choice" That doesn't seem like the ordinary definition of the term, either in philosophy or in everyday usage. I would think most people would define "having free will" as not just feeling that one could have made a different choice, but rather it actually being physically possible for a different choice to have been made. > "qualia" means "specific characteristics of experiences that one can attend to" I think those are also equally nebulous. > One need not "insist" on anything to believe they are unique characteristics of our identity. The insistence is necessary, and invariably comes up. As soon as I say to someone "given your definitions of these concepts, I don't think they exist" they will say "well, I've started with the foregone conclusion that I cannot deny the existence of these things, so either you're plainly wrong, or we need to tweak our definitions and understanding of these things."
