I don't think you have to explain it from *primary* matter. In

Elimanating often the qualia and consciousness. Material
explanation explains only the behavior.
I'm not convinced though that comp is any better. It comes down to
saying qualia are computations seen from the inside. But you could
as well say they are brain processes seen from the inside.
He does not explain where the physical laws come from, nor does he
addressed the consciousness issue.
But of course you need to develop your understanding of the mind-
body problem. The english literature contains many good texts.
Then the UDA explains how to reformulate the problem into a purely
arithmetical problem.
But at the expense of turning physics and everything else into an
arithmetical problem. The problem I see with the UDA is that its
passivity is contagious. In order to function as an AI in the
world it needs more and more of the world to be subsumed into it's
computation.
Dear Bruno and Brent,
It might be helpful if you guys would chat a bit about what you
mean by from the inside. You seem to allude to a outside/inside
relation here. Could you flesh this out a lot more? I have some
thoughts of my own on this, but I would really like to see what your
thoughts are about this relation. For example, does it involve some
thing like a boundary that when crossed is equivalent to a
transition from outside to inside or the reverse? What would define
such a boundary for COMP?
In UDA the inside/outside refers to the 1-view and the 3-view, which
correspond to the content of the diary that the candidate takes with
him in the teleportation/duplication boxes, and the content of the
diary of someone outside the boxes.
In AUDA, outside/inside correspond to the Bp/ Bp p distinction (the
believer or prover versus the knower). Or more generally the # and
# p distinction. The inside obeys the modal logic S4, the outside
obeys to G, G*, from the ideal correct machine's view on itself.
