Didn't see this post until now:
Immanuel Can wrote:This is the point I doubt.
Some things are capable of being described gradualistically, and some are simply not . . .
You don't seem to doubt this, you seem to be sure that it's an on/off affair.
It could be an on/off affair, but I don't think there's a good reason to believe that it is. I'm not saying that anyone is sure that it's a gradation, by the way.
Either you're not quite understanding the problem, or you've somehow vaulted ahead of brain experts. Everyone else seems to see a major mystery here.
First off, it hardly matters whether everyone thinks something. That certainly doesn't make them correct. But I'm not at all the only philosopher who thinks there's nothing mysterious about it.
In Philosophy, it's called the "emergent properties problem."
You just can not help but regularly be patronizing, as if you know more about philosophy than everyone else, and you're educating everyone else. If you really knew more about philosophy you'd know that (a) I'm not the only philosopher who thinks that there's nothing mysterious about consciousness (and certainly many neuroscientists think that there's nothing mysterious about it on a broad ontological level), and (b) that it's actually called "the hard problem," not "the emergent properties problem," because "emergent properties" has connotations that many do not accept, whether they're physicalists or not.
Again, you've jumped ahead of the story. You've started with "brain materials, structures and processes." You haven't touched the question of why these mere materials have come to have what we call "consciousness" in the first place.
The materials that have consciousness are brain materials, structures and processes near the complexity of the human brain. They don't have consciousness because of something prior to that. It's a property of those materials, structures and processes, and not a property of other materials, or other structures, or other processes.
Not so fast. How did these materials first come to have any iota of "consciousness" at all?
Forget about cosnciousness for a minute. As a universal generality, all materials, in particular structures, and undergoing particular processes, have particular properties, right? All materials have properties that are only present with each physical change in those three factors (the materials, structures--that is relations of the materials, and processes--that is, the changing relations of those materials). So the way that any x "comes to have" the properties it has is by being comprised of the materials, in the structures, and undergoing the processes that it is at that moment. Those same exact properties do not obtain when the materials, structures and processes are different. Properties supervene on those three things. So consciousness is simply a property of materials in the structures and undergoing the processes that are typical of human brains.
For Evolutionism needs a story about that, or it's got a huge gap in its story regarding the appearance of consciousness from non-conscious materials.
There's no gap. There are different properties with all different materials, structures and processes. At every step in that there are different properties.
