Here is what Dennett has to say in his own words:
I think Dennett's position (functionalism) is
plausible. But that doesn't make it problem-free.
Functionalism reduces
all of consciousness to information feedback. A functionalist would be prone to say that things like AI might be conscious. It would even be able to experience something like pain, if it were somehow possible to identify the formula for pain (information-wise) and run it through an AI's neural net.
On the other hand we have
biological naturalism. This theory states that consciousness is something PHYSICAL... just like the functionalists say. But it is physical in the sense that that it is
causally reducible to nervous activity and brain states. Unless you have neurons that fire, you DON'T have consciousness. That's what a biological naturalist thinks. It has nothing to do with information. It has to do with the physical states of neurons. The issue that biological naturalists put before the functionalists is: there is no ontological reduction between brain states and
the quality of our conscious experiences.
Now, remember, both camps agree that consciousness is CAUSALLY reducible to brain activity. Neither camp proposes ectoplasm or any kind of Cartesian soul. They are both
PHYSICALIST theories.
The first "physicalist" in the Western tradition (who worked on the problem of consciousness) was-- my avatar-- Baruch Spinoza. According to him, our mental experiences ARE PHYSICAL THINGS. Why does he think so? Because of that causal reducibility that we were discussing earlier. He was one of the first guys to really start paying attention to that. His way of thinking is called "dual-aspect monism." It's a bit antiquated by now, but I think it gets the job done pretty well. I also (and this is a huge guess) think that Spinoza would tend toward biological naturalism rather than functionalism if he were alive today. But, again, that's just my personal guess. And even I'm only like 80% on it.
Don't feel neglected,
@vulcanlogician. I believe Iain McGilchrist's philosophy could also be described as "dual-aspect monism". For him the cosmos or simply nature would be the basis of the monism and matter and consciousness would be its two aspects. But I am still incubating what I think about this video and what to say. I do appreciate your effort to present Dennett's words in a useful light. Still thinking but in the meantime in my reading last night the discussion turned very logically from the rejection of Dennett's denial of consciousness (if that is really what his words meant) to the possibility that we might simply dismiss Matter instead. If lopping off one horn of the hard problem dilemma and consciousness can't be the one, how about the other? A ridiculous notion to me but I question whether it is quite as ridiculous as a plain reading of Dennett's words. All that follows is an extended excerpt from The Matter With Things, beginning on page 1607 on my Kindle:
CAN WE DENY MATTER ALTOGETHER?
Matter itself is an abstraction which no-one has ever seen: we have only seen elements of the world to which we attribute the quality, within our consciousness, of being material. It both substitutes an idea for an experience (which is a kind of event) and, in doing so, produces something static, no longer in process: no longer an experience, now a thing. According to Bohr, ‘isolated material particles are abstractions, their properties being definable and observable only through their interaction with other systems.’45 Materialism derives the only thing we undeniably know, the concreteness of experience, from an unknown abstraction: matter.
A number of philosophers had already come to this conclusion. Thus FCS Schiller wrote in 1891:
It appears that all we know of matter is the forces it exercises. Matter, therefore, is said to be unknowable in itself ... And yet it is perhaps hardly astonishing that a baseless abstraction should be unknowable in itself. And matter certainly is such an abstraction. For all that appears to us is bodies, which we call material. They possess certain more or less obvious points of resemblance, and the abstraction, ‘matter’, is promptly invented to account for them.46
And later:
All the sensible qualities of matter are due to forces, gravitative, cohesive, propulsive, chemical, electrical, or to motions (like heat, sound, light, etc), or ‘motive forces’. Matter itself, therefore, is left as the unknown and unknowable substratum of force ... It is not required to explain the appearance of anything we can experience, and is merely a metaphysical fiction designed to provide forces with a vehicle.47
But, as we saw in the previous chapter, energy needs no substratum. Above all, matter cannot be called on to bring about the ‘annihilation of the mind by means of one of [the mind’s] own abstractions.
In a 2017 essay entitled ‘Minding matter: the closer you look, the more the materialist position in physics appears to rest on shaky metaphysical ground’, Frank eloquently expresses both the mystery of consciousness and the puzzling reluctance of many biologists to entertain theories that venture beyond viewing consciousness as a result of processing in the brain. ‘Materialists appeal to physics to explain the mind’, he writes, ‘but in modern physics the particles that make up a brain remain, in many ways, as mysterious as consciousness itself.’ And he continues:
Some consciousness researchers might think that they are being hard-nosed and concrete when they appeal to the authority of physics. When pressed on this issue, though, we physicists are often left looking at our feet, smiling sheepishly and mumbling something about ‘it’s complicated’. We know that matter remains mysterious just as mind remains mysterious, and we don’t know what the connections between those mysteries should be. Classifying consciousness as a material problem is tantamount to saying that consciousness, too, remains fundamentally unexplained. 49
All this may be importantly true, but I think we should no more conclude that we can deny matter than that we can deny consciousness. Neither way out of our dilemma is at all satisfactory. What, then, can we say about matter? Strawson uses the word
physicalism to refer to a reality which is not antithetically divided into matter and mind, but incorporates both elements as indivisible. From this perspective he writes: ‘It’s not just that we don’t definitely know the nature and limits of the physical. We definitely don’t know the nature or limits of the physical. Physics may tell us a great deal about the structure of physical reality’, he writes:
but it seems that it can’t tell us anything about the intrinsic nature of reality in so far as its intrinsic nature is more than its structure ... It’s plain that the human science of physics can’t fully characterise the nature of concrete reality, even in principle ... On many matters, such as experience, physics is simply silent. If you’re not clear on this limitation, you have no idea what physics is. This isn’t New Age anti-scientism, it’s hardnosed physicalism.’51
If asked my view, I would say that matter appears to be an element within consciousness that provides the necessary resistance for creation; and with that, inevitably, for individuality to arise. All individual beings, including ourselves, bring forms into being and cause them to persist: each of us is not, ultimately, any one conformation in matter, but, Ship of Theseus-like, the conformation itself, the morphogenetic field, which requires matter in order to be brought into being, but, once existent, persists while matter comes and goes within it.Remember Schopenhauer: ‘Matter is that which persists and endures.’52 Since the development of new such form-fields in consciousness seems to be part of the creative process of the cosmos, the lending of persistence (for a while) may be matter’s peculiar role.
