But it's clear that what we can see of reality is made of more than just causality.
Not to me. For instance, while conciousness is still mysterious to me, it sure has causal power, if only the power to make me think of it —and the causal power to make Chalmers write papers about it.
I think what you're saying is that in the present, there's no difference between your current configuration having resulted from a life lived for 20+ years, and your current configuration having materialized five seconds ago. Well, if by hypothesis the configuration is exactly the same in the two scenarios under consideration, then the configuration is exactly the same. That much is true tautologically or by assumption.
I think I mean something stronger than that. You may want to re-read the part of the Quantum Physics sequence. The universe actually doesn't even encode the notion of different particles, so that talking about putting this carbon atom there and that carbon atom here doesn't even makes sense. When you swap 2 atoms, you're back to square one in a stronger sense than when you swap 2 numbered (but otherwise indistinguishable) billiard balls. Configuration space is folded on itself, so it really is the same configuration, not a different one that happens to be indistinguishable from the inside.
substrates matter, and just implementing a state machine doesn't guarantee consciousness, let alone persistence of identity.
Err… Let my brain be replaced by a silicon chip. Let's leave aside the question of personal identity. Is that thing concious ? It will behave the same as me, and write about conciousness the same I do. If you believe that, and believe it still isn't concious, I guess you believe in PZombies. I don't. Maybe changing my substrate would kill me, but I strongly believe the result is still concious, and human in the dimensions I care about.
For instance, while conciousness is still mysterious to me, it sure has causal power
I agree that consciousness has causal power. I'm saying consciousness is not just causal power. It's "something" that has causal power. The ontological deficiencies of materialist and computational theories of consciousness all lie in what they say about the nature of this "something". They say it's a collection of atoms and/or a computational state machine. The "collection of atoms" theory explains neither the brute features of consciousnes...
From Being a Realist (even if you believe in God):
My mother, who doesn't call herself a theist (I think she's agnostic), doesn't even accept realism. She doesn't even agree with this:
That's little more than tautologies here. Yet it elicited an impression of being forced to believe. I know because she told me about the totalitarian dangers from such narrow thinking.
I'm happy to have finally found the root cause of our ongoing disagreement, but now, how can I deal with that? It looks pretty hopeless, but just in case, does someone have a suggestion, or should I just leave it at that? (My ego doesn't like it, but giving up is an option.)
Now I'm relieved to know that in near mode, she's a complete realist. This craziness only shows up in far mode.
