Or provide inputs which give the appearance of a world, yes.

I'm not sure why this is a problem, however.

I think the point of the MGA is that matter isn't primary?

Comp assumes that computation is necessary for consciousness, and in practice, for us to carry out computation requires physics to support it, of course - but that doesn't mean it's *necessary* for computation. Computation might be able to exist in Numberland, or so I'm told. > (it's just not necessary that physics be fundamental, whatever that means). > It means it doesn't emerge from anything else. But if physics isn't primary then there's no argument anyway, because as far as I can tell comp seems quite happy with non-primary physics. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
