The Ontology of Subjective Physicalism, by Robert Howell

The Ontology of Subjective Physicalism

This paper outlines in explicit terms one of those theories of physicalism which attempts to address the hard problem of consciousness without elimination and without dualism.

The original reason someone mentioned it to me was because of my thoughts on the problem of consciousness resolving in what people will find problematic, namely scientific anti-realism.

This is a view which basically allows for scientific realism while also allowing for consciousness consistently: something in-between eliminativism and dualism that is not epiphenomenal. It’s also just a generally good review of the history of the arguments on the hard problem of consciousness.

I can’t find anything wrong with it as a metaphysics other than I’m uncertain about how much we need to cave to science in creating a metaphysics, but that’s not really the focus of the paper since it’s outlining something which is consistent and keeps both intuitions of (a kind of) scientific realism with (a kind of) consciousness realism.

Anyone have any thoughts on it? It’ll take some time to read through, so I don’t expect responses right away. But I’d like to hear others’ thoughts if they have them because the paper just seems so “smooth” to me: there’s not much to nit-pick, so I’m having a hard time with an “against the grain” reading.

Quite some time, given the occasional windows of opportunity to make headway.

The abstract seems like something I’d agree with. The inability of an objective description to convey subjective knowledge does not necessarily imply that subjectivity doesn’t supervene on the physical.
“there are some physical states that are subjective, in that those states must be undergone in order to be fully grasped.”
I absolutely agree with this. One cannot know what it’s like to be a bat. Given physicalism, one can in principle sufficiently describe a bat to the point of being able to accurately simulate it. Neither the computer nor the people implementing the simulation will learn from this what it’s like to be a bat, but the simulated bat will know.

That epistemic knowledge (redundant, I know) cannot be conveyed any more than I can convey my subjective experience to any entity that lacks it. We only presume a similar experience with peers such that discussion of such states has relatable references.

Mary’s room also illustrates this disconnect between objective and subjective knowledge.

I’m glad you’re reading.

He utilizes Mary’s room in an interesting way in the paper.

I look forward to your shared thoughts after you finish reading.

Thanks for sharing the paper. To contribute to further discussion, I share some reactions.

Two intuitions generate the core of the mind-body problem. On the one hand
there is the idea that conscious mentality, with all its Technicolor vivacity, is
bound to have aspects that elude the cold, objective descriptions of science.

Objective descriptions are “cold.” Why this metaphor cold ? Because objective means “unbiased.” Basically the standpoint is made as generic as possible. No value judgements. Just measurements.

On the other hand, there is the deep sense that everything is composed of the
same basic physical stuff, and that to think otherwise is to grant conscious
beings like ourselves a convenient pride of place in the world’s ontological
catalogue. Upon reflection, however, many people are inclined to give up
one or the other of these intuitions because they seem to conflict. On some
level one of the intuitions maintains that there is something “special” about
conscious mentality, while the other maintains that it is not “special,” but is
crafted of the same clay as everything else.

Is there a really a deep sense that everything is made of some basic stuff ? I grant that there is a common assumption of some vague X that functions as a truthmaker. This X, which comes in many flavors, is “external” or “really there.” So that statements are “true” or “false” in an absolute sense.

Also “conscious” beings don’t want to get big heads ! So it’s “good” to be a physicalist. It’s even a duty. Which goes against the “cold” mentioned earlier. We are warm about being cold. The colder the better. The colder the more truthful. There is something in this, but taken to the limit it’s nonsense. Or ?

We are warm about being objective. About practicing a certain art of the generic quantitative standpoint. We are so warm about being cold that color becomes “unreal.” Yet most of those measuring the world, repressing their feelings about it, still see it in color. Still feel something, that they omit from the report. What goes in the report, and only that, is “real.”

A decision to ignore most of the world within a certain game results in a forgetting of the context of that game. The context of that game, social sensory reality with values and feelings and norms, gets transformed into an illusory internal stuff.

Some physical properties can be grasped only subjectively. The properties
that underwrite conscious experiences (e.g. qualia) are physical, but they are
not identical with any property mentioned in a completed physics.

This is strange stuff ! A “completed physics” ( unpack that ! ) does not include certain physical properties.

All physical properties can only be grasped “subjectively.”

Am I saying something radical here ? I don’t mean that an image of the world is in my head, an image made of “qualia.” I just mean you or I perceive this or that. And you or I understand this or that piece of physics.

The “from-a-point-of-view-ness” of perceiving and understanding the world ( of the world’s being there and showing itself ) gets misread in terms of perceptions being non-world stuff in the head.

So much of what’s called “physicalism” ends up being dualism with a privileging of the “homogenous external stuff” as pseudo-primary.

This slightly modified version of Jackson’s argument goes as follows. Mary
is a brilliant scientist who has lived her life in a black and white room. During
her prolonged imprisonment she was taught all of physics, neuroscience, and
biology through black and white computer screens. In fact, she eventually
gained all the information about the world that could possibly be conveyed
to her through such screens and monitors. At that point she had all the
objective information about the world. Nevertheless, when she left the room
to be presented with a red rose by her captor, she saw the red of the rose and
learned something new—she learned what it is like to see red. Thus, not all
information is objective information.

She studies physics, appropriates important and warranted beliefs. But why is physics not just numerology ? Or beautiful mathematical fantasy ? What constrains the math ?

Perception. Observation. Of colorful and noisy objects by a generic observer. By many actual observers, but the point is to “lift away” from particular observers. The theory predicts the perceptions of unborn observers.

So “objective information” here is about generic perceptions in the future. An observer can’t loan us his or her eyes or ears. They write that the measurement was this or that. That process of measurement is ignored here. The leap to the generic observer tacitly becomes a leap from the “quality” that becomes numerical through measurement.

This “objective information” is presented like the “mind of God.” The word “objective” leaps from “no relevant bias” to “in the mind of God.” This “mind of God” is “true” apart from the perceptions that made us take it seriously in the first place.

I didn’t get very far with this paper because I had trouble understanding how the author was using the words ‘subjective,’ ‘objective,’ ‘physical’,’ and ‘consciousness.’ I’m no philosopher so forgive my intrusion, but my brief acquaintance with some of the writings of William James has led me to a profound change of perspective.

In his Essays on Radical Empiricism, James repudiates the idea of consciousness as substance, and re-deploys the word ‘consciousness’ for a function in place of this repudiated substance. But he still has to appeal to the fact that all of this activity is arising, and he recruits the term “pure experience” in order to allude to this.

In later works (Some Problems in Philosophy, and Pluralistic Universe) James seems to have softened his distinction between these two. It seems to me that having dispensed with the idea of consciousness as substance, he may have felt drawn back into using the word ‘consciousness’ in place of the more cumbersome term “pure experience.”

From the vantage point of James’s pure experience, the concepts ‘physical,’ ‘mental,’ ‘subjective,’ and ‘objective’ are just ways that pure experience divides into categories. So, having been swayed by James’s philosophy, to me any attempt to squeeze consciousness (pure experience) into a category of itself seems perverse.

Am I missing something?

I agree. “Pure experience” is a gesture toward “the total fact.” I take the word “experience” to gesture toward the “for-me structure” of this “total fact.”

James almost “had” to use “experience” to remind people of this total fact, since so many were in the habit of using “reality” for a curated fragment of this “total fact.”

Yes, I think that’s the same error that I was alluding to. We regard a category of consciousness as ‘reality’ and then wonder why we can’t find a place for consciousness in ‘reality.’ Some solve this irritating problem by claiming that consciousness is an illusion (eliminative materialism) – it’s like they put the cart before the horse and then can’t find a use for the horse so they shoot it.

Yes. You got a laugh out of me with this one.

On the first page the author says it’s important to maintain a “rigorous separation between epistemological and
metaphysical issues.”, and I agree. Yet in the article the words ‘subjective’ and ‘objective’ are used ambiguously between epistemological and metaphysical senses via the figurative expression ‘grasp’. For example:

  1. A full physical description of the world leaves nothing out. All properties can receive objective, physical descriptions. Nonetheless, there are some properties that cannot be grasped fully unless they are grasped subjectively, via
    conscious experiences, as well as by objective physical descriptions.
  2. Some physical properties can be grasped only subjectively. The properties that underwrite conscious experiences (e.g. qualia) are physical, but they are not identical with any property mentioned in a completed physics.

What could it mean to grasp physical properties "only subjectively?

Any experience is subjective. Doesn’t matter if it’s a private headache or a public building. Both are ‘subjective’ in the sense that they exist only for the one who has them. This is the metaphysical or ontological sense of the word ‘subjective’.

Your knowledge of your own headache is also subjective in the sense that it exists in your head, but that doesn’t mean that it’s epistemically subjective. You can have epistemically objective knowledge about your head ache, and share the knowledge publicly by means of language.

There’s certainly a difference between experience and description. A description is seldom sufficient for learning a craft or a sport, and in this sense I believe there’s some knowledge that you acquire only by doing things. But that’s not a shortcoming of descriptions.

It seems trivially true that a full description of the physical reality omits what one has yet to learn and describe.

I have not read the whole paper, but one thing it seems to omit is that it assumes that matter is most fundamental while ignoring the view that math is more fundamental than matter. At the same time, its “monism” seems to be defined in opposition to mind-body dualism, which is what it appears to mean by “dualism”, rather than in a rejection of a privileged position of math in the universe. (I myself am a dualist in that I believe in a separate ideal realm of math while I reject Cartesian mind-body dualism.)

I’ll definitely read it. Gotta finish something up first…

Funny that I posted (mentioning Mary and bats) just before he got into both. He uses Mary to turn the dualist conclusion on its head by making her the expert in ‘ectoplasm’, but still not being informed of any subjective facts.

I got lost around the conceivability argument around pg 13, acknowledging that the argument has teeth when I never thought it did. To me it’s like, “I’m willing to entertain utter implausibility, therefore it must be the case”. Sure, Howell addresses the argument, but I never thought Chalmers had an argument to start with.

Objective is the antonym of several things, and here they mean ‘not subjective’ as opposed to ‘biased’. Often when discussion ontology, I use the word to mean absolute, or ‘not relative’.

I don’t think it is within the scope of this paper to ponder what the physical (some of which is matter) might in turn supervene on. It’s about physical being enough, there not being some 2nd thing to the side, neither supervening on the other. This fairly old view admits that a full physical description cannot convey subjective knowledge, and why that’s not a problem.

For a lot of people, sure. And even if we are recalcitrant to attribute “stuff” because of worries about substance (which includes me) there’s still the intuition that it all hangs together somehow: even if I end at relationship or process as the turtles all the way down rather than things there’s still this notion that I’ve arrived at an ending: however I render it, all the “stuff” hangs together in a kind of unity: for many even though I feel like such-and-such there is a deep sense that there’s some explanation for that experience which bottoms out in the world we inhabit, be it idealist or materialist.

It can result in that, but if we reflect then it seems – like ourselves here – we’d start being a little cautious about inferring things from a particular way of describing the world (which, necessarily, ignores most of reality) to a general understanding of what reality fundamentally is.

Here we might say that the game is taking place in the ontology room which is attempting to unwrap that possibility while acknowledging it’s something of a game.

Yup. That’s the takeaway of the position being described. And really he’s more pointing out that one may hold both intuitions at once, given this consistent stance, not that this is the best way to look at the world as a whole per se.

I’m not sure it’s so radical here. “Grasp” could be stipulated to be the subjective side of understanding. But I think that’s not exactly what the paper is getting at. It seems to me that we can grasp physics – which, for purposes of this paper, serves as the “objective” physicalism (which may include intentionality in it, which is kind of how I read you here when talking about point-of-view), but there are still some physical states of affairs which the objective physicalism leaves out, namely whatever “qualia” tends to refer to. Also note here that the view he’s defending is the inclusive version which weakens the claim somewhat to say that there are only some aspects which can only be fully grasped through the subjective, like the sensation of pain (as opposed to the behavior of pain).

Yup. Dualism has a way of reappearing everywhere.

I think we can skip this explanation of “objective” and say “however you want to cash out scientific facts, like physics, is what we mean by objective physicalism”: for an idealist the mind of God, for the materialist the inert fact, but either way both can point and share the measurement whereas they cannot share their experience of the measurement. I’d put it that “objective” changes with time and place and practice and all that, but there are still general “rules” that arise from practice that people utilize to work together in generating knowledge, and that’s close enough to count for “objective” for the purposes of this paper.

I see the argument. It’s not persuasive to an eliminativist, but the argument follows through well enough. I’m not sure it’s sound, but that it has traction is enough want to address it.

I found the re-dressed Mary’s Room argument interesting. Given subjective physicalism it makes sense to say Mary does learn something more, even if it isn’t the sort of knowledge we tend to mean.

Let’s say that it means “not-objectively”, where “objectively” is something like modern physics, chemistry, and biology. (or, better, a perfected version of these in the future – since everyone will admit that right now things are “left out” of science, since there are more questions)

Nope, you’re just reading the paper from a different perspective. You’re thinking about it from the perspective of William James’s Pragmaticism Pragmatism, whereas this is a paper that’s written in the tradition of contemporary analytic metaphysics.

It’s not so much that you’re missing something as the paper starts from entirely different concerns than William James, and utilizes the terms differently from James.

It assumes that because that’s the assumption he’s working from in the beginning. Howell’s not arguing that this is the one true metaphysics. He’s pointing out a possible way to reconcile two common intuitions that are frequently thought to conflict upon reflection.

The argument is more “If you reflect even more, here’s a consistent way to hold both beliefs”

If you don’t hold both beliefs then the paper is something of a non-starter for your beliefs, though it is worthy to understand why others believe as they do even if you don’t believe as they do.

The words ‘objective’ and ‘subjective’ tend to create false dichotomies. Such as “science is objective, experience is subjective, and therefore some knowledge can’t be objective, and what’s subjective can’t be science”.

So let’s clarify the epistemic and ontological senses in which the words ‘subjective’ and ‘objective’ are used.

You can have epistemically objective knowledge of physical properties, despite their objective mode of existing and the subjective mode in which your knowledge and experiences exist. We can have and share epistemically objective knowledge of the ontologically subjective domain of our individual experiences, headaches, joys, thoughts etc.

Now, what could it mean to know (grasp) physical properties “only subjectively”?

It’s trivially true that you grasp things “only subjectively” in the sense that experiences and knowledge exist in your mind. But if the experience is epistemically subjective, then the question arises… how could it be an experience of anything ontologically objective such as physical properties?
