I actually have a degree in Philosophy — Douglas Alan
Welcome to the club.
:-) You should post in
this poll thread if you haven't already. (Also I could use some more educated eyes of at
this project if you have some time).
The mystery of why the contingent facts are what they are reduces simply to which world we happen to be located in. And there's no mystery in that. — Douglas Alan
Okay, it wasn't clear that that's what you meant before. Sounded more like you just didn't understand modal realism (which you clearly do, now).
We're just going to have to disagree on this. For me, it's a Moorean fact that real phenomenal consciousness cannot arise from nothing but pure math. — Douglas Alan
I'm guessing you're referring to something like the Open Question Argument here? I'm a big fan of that line of argument in its original use but I've never heard that applied to the topic of phenomenal consciousness before, only moral semantics. I don't see how it could clearly apply to the topic of phenomenal consciousness either. Moral questions are asking a different kind of thing to which no descriptive fact can be an answer, so giving a descriptive answer to a question of prescription is a non-sequitur that just leaves open the original question entirely. ("Is it good to save people from torture?" - "It decreases their suffering." - "And
is that good?") I don't see how something like that applies to phenomenal consciousness. I'm guessing you're thinking something along the lines of how no functional account of the objective behavior of a thing can tell us anything about whether it has a subjective experience; that is a point I've made here over and over again, and used as a crucial part of an argument for panpsychism. But just because an
account of function doesn't
account for experience doesn't necessarily require there to be, for example, something non-physical to have the experience, or something non-mathematical in this case.
Here's a very loose argument (I'm winding down for bed and therefore lazy) for why mathematicism actually meshes better with the existence of phenomenal consciousness than a more conventional kind of physicalism: mathematical stuff is easily understood as mental stuff, as ideas in the mind. (Your comparison to Platonism below makes this clear). If the physical world is made up of math, and human minds are instantiated in physical structures, it's much less weird that those physical structures should be able to do mental things, given that they're actually made of mental stuff to begin with. In the stricter, less dualistic terms that I would prefer to think of it, if everything is informational at its base, of a kind akin to what thoughts are composed of, so physical structures are informational structures, physical processes are informational processes, then it really shouldn't seem so weird that some of those informational processes should constitute thought processes as we're familiar with them. It would be weird if
only human brains had anything mind-like about them when everything was made up out of the same mind-stuff... but panpsychism gets around that, by saying yeah, everything is kinda mind-like, everything has something like the phenomenal consciousness that we do, some kind of subjective experience or another, most of it radically less complex and interesting than ours, but the more like us they are in function, the more like ours is their subjective experience too.
I tried to explain MUH to him after the talk, I was having a hard time until I described it as "radical Platonism". — Douglas Alan
"Mathematicism" seems to be the usual term used in philosophy circles, so maybe that would get more people's comprehension. And IMO it's more Pythagorean than Platonic, though I've heard it described as "radical Platonism" too. But I don't like that: I'm strongly anti-Platonist, as he separates the ideal from the physical, and debases the physical as not living up to the ideal, while I don't see mathematicism (whether ancient Pythagorean or modern Tegmarkian) as doing that. It's much like how I'm strongly anti-dualist but partial to something like (a more Berkeleyan, not Platonic) idealism, because it doesn't say that the mental is something apart from the physical, but that the physical is subsumed within the mental; likewise, mathematicism, unlike Platonism, doesn't separate the mathematical or ideal from the physical, but subsumes the physical within it.
