Thomas Nagel reviews Daniel Dennett's latest I enjoyed Dennett's paper, "Two Black Boxes," but whenever I read his stuff on consciousness, I immediately sense that he's trying to hoodwink me.
What doesn't sit right is this: Dennett wants to say that common-sense things, like emotions and macroscopic objects and such, are illusions of the manifest image, but that we ought to regard them as real because they're useful. He's basically saying, "It's all just pretend, but it's fine that we pretend, as long as we keep in mind that we're pretending."
On the one hand, I see the merit of this. It certainly helps to keep in mind that the representation is not the thing that it represents, and the reification of representations is, indeed, a philosophical pitfall. The problem is that Dennett wants to claim that the only thing that isn't a representation is physicality. Of course, pretense itself is also a user illusion, but it's okay for us to pretend that there's such a thing as pretending. :s
I am quite comfortable with there being a physical description of all subjective phenomena. It bothers me not one whit that the thoughts I form while writing this all correspond to brain states, or even that they are brain states. I'll even grant you that the neural descriptions are far more useful, if you're doing neuroscience or something similar. The third-person perspective can be primary for methodological reasons, but why grant it ontological primacy? Dennett's answer, ultimately, is "because it's useful to do so." But things are the way they are, regardless of what is useful to us, and Dennett would, no doubt, agree with that. And if utility determines ontology, then why not assume the manifest image is real as well, since we need that too? You can even argue that the manifest image is more useful; we survived for millennia with it alone, and we still use it more often in our lives than the scientific image. More to the point, if Dennett is so adamant that things are the way they are regardless of what's useful for us, then why does he base his ontology on utility in the first place?
The manifest image is "the world according to us," yes - as is the scientific image.
