One of the reasons why I am not satisfied with such a position is that consciousness appears to be unnecessary from an intelligence / Darwinian standpoint. It appears that Darwinism + neuroscience/computer science can explain the emergence of our behaviour in non-conscious zombies. It has been argued that it could be a spandrel, a by-product of the evolutionary process. I have no problem with that -- in fact I am betting this is the case, because I doubt that a non-conscious human-level intelligence is possible. But I still want to know why. Every time a problem baffles us, and people suggest that: "look, it's just a brute fact", I can't help but feel that this stance is very akin to saying "the gods did it". One of the things I like about Bruno's work is that I fell that he, at least, provides a theory on why it looks so mysterious to us. What also baffles me is why some people can't see the mystery. I don't think this is the case with Brent though, I think he is a pragmatist -- which is a perfectly reasonable thing to be. > To go beyond this, as for example Bruno is attempting to do with the comp > theory, requires an explanatory schema that somehow manages both to > transcend and encapsulate the explication of conscious phenomena in > exclusively reductive terms.

After all, the attempt to understand consciousness amounts to something creating theory on itself. After all, we only have the first-person view. The third-person view of reality is an abstraction. Independently of one's position on MWI, comp, physicalism, idealism, etc, one only knows reality in the 1p. Trying to understand consciousness is trying to understand 1p from the 1p.

Yes, I think you make an interesting distinction above. I think I agree. It's funny because I argue a lot with Brent on this, but I am not opposed to pragmatism. I love AI, and would love to know more about how to reach human-level-AI. But there is a deeper dissatisfaction that I insist on, and others (perhaps more wisely) don't.
