It doesn't seem objectively unreasonable to me that physical processing should give rise to a rich inner life. It seems clear to me that it can and it does. Note I said "clear," not "obvious" or "established." I certainly could be wrong. I look for reasons why it should seem unreasonable to others and I can come up with two answers. 1) Cognitive scientists seem to be a long way from identifying the neurological mechanisms that manifest as experience. I'm not really sure how true that is, but I don't think it's a good reason. 2) People just can't imagine how something so spectacular, important, and intimate as what it is like to be us could just be something mechanical. — T Clark
Thanks, that's interesting. I've taken the liberty of bolding a few of the words in there. I want to make a list of verbs that have been used to characterise the relationship between consciousness and a physical system. Perhaps as the basis for another thread, I could do a poll maybe.
As to the substance of what you say:
1) This perhaps is related to arguments from ignorance. I've been told that's what I'm doing several times, and that might be right. Maybe I just haven't read enough neuroscience. Maybe I lack faith in the scientific method which, after all, is easily the best method we have had so far in our history at arriving at reliable/true/useful theories about the world. Philosophy, which again has been pointed out to me many times, it completely fucking hopeless by comparison. Having said all that, the issues seem to me to be
conceptual rather than
empirical. Sometimes scientists need philosophers to help them out a bit with the concepts (yeah that's patronising, I don't care. Just as philosophers are often shit at science, scientists are often shit at philosophy too). One example of an important conceptual matter is the idea that consciousness does not, conceptually, seem to admit of borderline cases. Another example is the separation of different senses of 'consciousness', which Chalmers apparently does as you've quoted. Lexicographers also have a role to play here in clarifying what it is people actually use the word for. Maybe hard-bitten neuroboffins on the one hand and fairy woo-mongers on the other are talking about different things and are failing to actually disagree.
2) That may be true of some, but I don't think it's true of many philosophers. People like Brian Cox and Dawkins make much of this point - going on and on about how the wonders of the natural world are not diminished by their physical basis. I think it basically a straw man, no serious woo-mongers actually make this point.
And of course the mind, and in particular experience, isn't just something mechanical, just the operation of the nervous system, any more than life is just chemistry. The mind emerges out of neurology. The mind operates according to different rules than our nervous system. We call the study of the mind "psychology." I don't have any problem conceiving of that, even though I don't understand the mechanisms by which it could happen. — T Clark
(Collecting my list of verbs again) OK, so you're a non-reductionist about the mind. That's obviously fine but it creates a problem. If mind isn't just the operation of a nervous system, what is it? A simple unsophisticalted identification (the simplest way to be a physicalist) between neural activity and consciousness is no longer an option. One option is to take a hierarchical systems approach, saying that whole systems and sub-systems have properties unique to each 'level' and these have upward and downward causation powers, and that various components of mind, including consciousness, is somehow captured with these concepts. I think
@apokrisis thinks something along these lines (no doubt I have got it wrong somewhat wrong).
If there are other reasons for rejecting a neurological basis for phenomenal consciousness, you haven't provided it. You've only really found fault with reasons why scientists say there is one. Your argument is primarily a matter of language, not science.
Sure, but it depends what you're looking for. I don't have a falsification. For example, I can't take
@Nickolasgaspar's theory, use it to make a prediction, and then make an observation that falsifies that prediction. So if that's what you want from a critique, I can't offer that. One thing philosophers can offer is a mapping of the theoretical landscape, so the broad options are all clearly visible, and the pros and cons of each laid out. Then we can provisionally pick one as a result of an abductive inference. The joke I don't get tired of repeating is taken from Churchill: "Panpsychism is the worst theory of consciousness apart from all the others." The idea here is roughly that one of three options must be true: eliminativism, panpsychism or emergence. We pick the least problematic.
As for the function issue, we're not really talking about brain function, we're talking about mind function. I'm positing that not neurological function but neurological mechanism and process are the basis of mind function.
Don't quite follow that bit.
I think most would agree that phenomenal consciousness is a valuable mental resource and capability.
Sure, absolutely. As a panpsychist I go much further, and assert that any behaviour at all, including the behaviour of atoms, is valuable for the mind of the atom. Everything happens because of consciousness. I've been toying with the idea that all causation is actually psychological. We move about and do things because of how we feel. So do atoms and molecules and everything else. That's not to say mechanism doesn't exist. Just to say that mechanism is derivative of will, and a macro-effect supervening on lots of things all doing what they want.
@Banno mentioned the difficulties with the concept of physical causation and linked to the SEP article, for which I was grateful. I need to read that more and reflect. The whole idea is a bit of a switcheroo.
Have to stop there, back to work for me. Thanks for interesting post.
