I recently did a post on Riccardo Manzotti’s interesting IAI article: There is no problem of consciousness (warning: possible paywall). In that article, Manzotti described his Mind Object Identity hypothesis. He also published a paper on this idea in 2019, which goes into much more detail.
A quick recap. We make a mistake, he argues, in trying to situate conscious experience inside the brain. Instead, we should view our conscious experience of an object, like an apple, as the object itself in relation to our body. And our memory, imagination, or hallucinations of the object as that object in the past in relation to our body. In other words, we shouldn’t look for the redness of the apple in our head, but at the apple itself. It’s an argument for revising our way of thinking about consciousness.
After that post, Dr. Manzotti contacted me and offered to engage in a brief dialog. Below are answers he had to a few questions I sent. I’m posting them with his permission, and opening this up for wider discussion.
1. With MOI, is there anything special in the relationship between objects and brains (or similar information processing systems)? Or is there conscious experience in any collection of objects in relation to each other?
First and foremost, MOI is not panpsychism. MOI is the identity between one’s consciousness of objects in the world and those objects. For example, what is the physical thing that is Jane’s consciousness of an apple? It is the apple as it happens relative to Jane’s body. The emphasis on the relative nature of external objects is important because it explains why there can be physical features that do not belong to Jane’s apple. For example, Jane is oblivious to any neutrino’s related features of the apple. So the apple that is consistent with Jane’s experience is a subset of the physical properties that make up the apple as an absolute. Yet they are all physical and taken together they make Jane’s apple. It can also be expressed as Jane’s body carving out a subset of the physical world, which we usually refer to as Jane’s consciousness. This is MOI! The remarkable thing is that this is a real explanation, because it explains what consciousness is in the physical world without appealing to specific phenomena and without leaving anything to be explained.
So, please according to MOI there is no consciousness experience spread in the world. This is a crazy idea of panpsychists that does not really explain anything.
Each brain carves out a different subset of the world. Such subsets are carved out because they are able to produce effects using those brains – the subsets exist relative to those brains. No emergence. No panpsychism. No special properties.
2. If the answer to 1 is that brains matter, what distinguishes MOI from a view that sees all those external objects and their interactions as causal precursors to experience in the brain? Is there a fact of the matter on where the experiences actually happen?
As I said above, there is no experience qua experience. There is no magic place where experience happens. There is no conscious apple flashing out somewhere. There is just the apple. MOI states the identity between consciousness and existence, between one’s experience and the objects in one’s existence. It’s a form of reductionism if you like.
For MOI, brains matter insofar as they provide the circumstances where an object can produce an effect and thus can exist.
Let me provide you with an analogy: relative velocity. Take a body in space. Does it have any velocity by itself? No it doesn’t. It has a velocity only relative to other objects that provides a reference frame. The reference frame which is another body provides the circumstances that allow the first object to have a given relative velocity.
Many believe that the brain causes consciousness like, say, the heart causes blood pressure. No! It’s the other way round. The brain carves out external objects like, say, a lock carves out its key, which would just be a scrap of metal if there were no lock.
The idea of relative existence is that: Brains offer objects the opportunity to cause effects. The mind is identical with such objects, rather than with the brain. As regards the traditional idea that the brain causes consciousness, it’s the other way round. The brain has a role but it does not cause consciousness. External objects causes effects in the brain (is it not what happens in everyday experience?) Such objects are what has been called consciousness and has been mistakenly taken to be some mysterious activity in the brain.
3. If brains aren’t required for simpler versions of conscious experience, then since objects in relation to each other is a universal condition, why wouldn’t this be a naturalistic form of panpsychism?
Because panpsychism is committed to the idea that phenomenal experience is something over and above the standard physical world. For panpsychism, consciousness is liberally spread everywhere rather than being associated only with human brains (as the dualists do). In a sense, panpsychism is dualism on steroids.
MOI is totally different. MOI states that there isn’t such a thing as consciousness as something different from the world. Nobody has ever experienced a mental apple next to a physical apple. We have always found apples. And MOI tells us there were physical apples. In this view, there are just objects. When you are made of an object that object is part of your existence. If I asked you to describe what you find in your experience, you would describe an apple, not an image of the apple.
4. You mentioned in a comment that MOI is an empirical hypothesis rather than a philosophical one. What could falsify it?
MOI puts forward all kinds of testable consequences and predictions – a very strong one is there cannot be an experience made of something that a subject never met in the physical world. In short it means that, no matter to what extent one’s brain is internally stimulated, either by means of drugs or other physical means, one cannot perceive or imagine something that is not physical.
So falsify MOI is super easy: just show me one case where a subject has an elementary experience of something she has never met in their life. Show me a congenitally blind subjects who dreams of colors, for instance. Or show me a virtual reality color that does not exist. Or one case where a subject is able to conceive and imagine an impossible color (as for instance an intermediary hue between blue and yellow which is different from green). Such a case has never happened.
As it happens our dreams and imagination, hallucinations even, are totally constrained by the physical world. At most, as René Descartes himself claimed, we can imagine combinations of such physical properties and particulars, as when we imagine a chimera.
A warning. There are a few very rare anecdotal cases of allegedly miraculous experiences (such as the infamous anophthalmic Turkish painter who claimed to “see” colors in his mind). All such cases have been debunked.
5. How do valences and affects factor into MOI? Where would MOI consider them to occur?
Valences and affects are relatively easy. They are a combination of the body plus the external circumstances. For instance, fear is then the body tries to avoid something and, at the same time, gets in a very stereotypical state /heart pressure, heart rate, etc.
6. You note in the IAI article that MOI has no room for ideas, yet it seems as a species capable of symbolic thought that ideas play a crucial role in our experiences. Is this view mistaken?
Look at what’s happening with LLM (Large Language Models) such as ChatGPT and the like. They seem quite good at producing text and content that, if it were produced by humans, would require the notions of idea. Yet, nobody thinks that LLMs have ideas in addition to their code and data. Ideas are fictionary entities no one has ever seen. They have no causal role. They do not exist. Rather than ideas it is enough to refer to what those ideas are about.
Any other questions for Dr. Manzotti?
SelfAwarePatterns 
Hi Dr. Manzotti,
Some follow up questions.
I’m wondering how you see your hypothesis in relation to direct/naive realism?
https://en.wikipedia.org/wiki/Na%C3%AFve_realism
In your answer to my second question, you note that brains offer the opportunity for external objects to cause effects. But these are effects in the brain. I’m wondering why it doesn’t make sense to equate these effects with the experience. This seems particularly tempting since different brains may have very different effects from the same object, and it’s brains that are able to hold such effects from objects encountered years ago.
Regarding your answer to 4, the example that first came to mind when reading it were Platonic solids. These seem like idealizations no one ever encounters in the world, or to be precise, idealizations the first people to come up with them couldn’t have encountered. I know we’re able to imagine objects and their attributes in novel combinations, but at some point it might seem arbitrary to insist these aren’t completely new concepts.
Under your hypothesis, what would your response be for the Mary’s Room thought experiment? Given your response to 4, it seems like we’d have to say Mary learns something new because she hadn’t interacted yet with the relevant objects. But if she did have complete knowledge of the effects of those objects, would that still be true?
Ok, I’ll stop there and let you respond and others weigh in.

We have an empirical answer to that: congenitally blind subjects have no visual experience if their brains are electrically stimulated.
But what if we stimulated the receptors? Unless you think receptors have “mental colors” inside, there is no reasons anything should happen. In fact, color receptors are such if we put them in the right circumstances to work as such. Otherwise they are cells with the capability to release opsin if stimulated by various means (among which surely light rays but not exclusively).
We describe them as color receptors, but they are such only in the right circumstances.

“We have an empirical answer to that: congenitally blind subjects have no visual experience if their brains are electrically stimulated.”
Can you cite a study about that?
I do know that congenitally blind do not dream in color (or even dream visually, I think). In fact, I think color in dreams goes away if vision is lost before two years old. Congenitally blind people who have had their sight restored need to learn to see.
This tells us that learning is involved in vision. The congenitally blind usually lack a connection between the eye and brain or have damage or lesions in the visual cortex. So that wouldn’t tell us what happened if Mary’s red color receptors were triggered. When they modified green light cones in the eyes of male squirrel monkeys so they would be sensitive to red, the monkeys after time learned to see red. So red must be product of receptors and the brain. Does whatever study you are thinking address the learning requirement?

Thanks for your response. Unfortunately, you’ve stepped out of the confines of the thought experiment. In actual fact, if Mary were raised in a black and white environment, she would be unable to see any colors, as those parts of her brain would have been repurposed, as happens in the congenitally blind.
But if we accept that Mary is in a state that she would see the redness of the strawberry if she were exposed to it, i.e., all the neural machinery is there and functional, then it should be possible to activate that machinery in the absence of something red, yes?

For me, Mary would see a color, because Mary would be a color (a relative property in the external world).
For you, Mary would see a color, because Mary’s receptor have the secret juice to trasnform rodopsin in colors and the pumping them up to the control center in the brain where a homunculus sees “phenomenal colors” or “values” or “colors in a model” (quoting from other threads here), which are totally invisible to any scientific enquiry. Or, maybe after some “learning” which is basically some time you give neurons to learn the recipe to cook mental colors out of neural signals.

Just to let you know, for me, Mary would see a color for reasons a lot closer to your reasons than you think.
For me, Mary would see a color because the mechanism that gets triggered is correlated with seeing the color, because it was naturally selected for that correlation. This correlation, sometimes referred to as mutual information, is not a physical property. It’s an informational property. And as you say, the correlations are relations between (parts of) the brain and physical things in the environment.
I read your Mind Object Identity theory as simply redefining “you” as the set of these correlations, which is fine. But I think it stretches the common understanding of identity too far, unless there is some practical purpose that it serves, which purpose i haven’t seen yet.

What is mutual information? (I know what it is of course). yet, does it have color?
Of course it has not. You postulate information must, nobody has a clue as to why and how, become colors or, since such a woring looks too dumb, “to be interpreted as colors”? “to create a model of colors”? “to ????” What? Why should the appeal to mutual information? or integrated information? or magic information be of any help?
Is the problem of going from information to colors any better than going from neural signals to colors? No it is not. If anything it is worse. At least neural signals are physical entities. Mutual information are abstracts, descriptive fictionary entities.
Once again, I don’t care about the common understanding which is clearly failing here. We need simply to start from scratch and ask ourselves, given the physical world, what is the better match with what we call “conscious experience of the world”? I propose the identity with the most logical option, namely the world itself. You keep looking for mysterious invisible unphysical entities … mutual information is just another ghost.

Thanks for your comments. Let me reply orderly.
1. “But these are effects in the brain. I’m wondering why it doesn’t make sense to equate these effects with the experience. This seems particularly tempting since different brains may have very different effects from the same object”
The effects in the brain do not have any of the properties we find in our experience, thus they are not our experience. How many times will I have to stress this elementary fact? Since they do not have the properties of out experience, it follows that they are not our experience. There is no way to escape from this conclusion.
Moreover, you say that equating effects inside brain with experience is very tempting since brains have differente effect from the same object. Well, this is the opposite of what happens. In fact, to the best of our everyday life, our experiences are very much identical no matter the neural differences. We all see yellow bananas and red strawberris and we all continue to perceive them remarkably in the same way, no matter the differences in our brains. Morevoer, during our own life, neural representations keep changing (the well known phenomenon of representational drift), yet our experience of, say, a yellow banana, stays remarkable identical during all our life?
You say there is something that is different between your perception and mine of the yellow banana. Such a residual change is due to the relative nature of physical properties, rather than to a subjective experience inside our brain.
2. Concepts are not something we perceive. We can conceive of N-Dimensional spaces, yet we do not experience them. Platonic solids or abstracta are not consciously perceived.
3. The Knowledge Argument, as famous as it was, lumps together knowledge and experience. Mistakenly in my opinion. Mary knows everything but she has not experienced everything. The two things are different. Today, with AI we are facing examples where AI systems have knowledge without having experience. I belive the knowledge argument made sense in the 70’s when Frank Jackson was developing his ideas but it does not long hold its grip on the debate.
Thanks again!

With thanks to you and to Dr. Manzotti for this rare opportunity, I’d like to follow up on your question 3. Is a human brain or body necessary for consciousness? For example, a worm eating its way through an apple could be said to have a relationship to that apple not dissimilar from that of a human who eats it, or touches it, or looks at it. Does this mean the worm is conscious?

Excellent question.
Based on my hypothesis there is no magic threshold above which a system becomes magically consciousness. There is just the world taking place as a bundle of events/objects. Each objects brings into existence other relative objects. Some of such objects are just quantitatively more articulate. So, say, a table does not bring much into existence. Only weights. Its relative world is rather dull.
A worm’s body brings into existence many more relative properties.
A human being’s body brings into existence more and more complex properties. This is its world, which is a physical world.
A big difference between human beings and worm is likely in the time span of their world. A worm is mostly reacting to events that have taken place in temporal proximity. A human beings (and many mammals) actions are conditioned by events that took place anywhere in their lifespan (decades or more).
Yet, and this the crux of the matter. Nowhere there is the need of adding something like phenomenal character to what’s going on. There are just objects and their properties. It’s all we need.
Phenomenal character has been invented to justify a “miniworld without matter” inside the body. Once we accept that the apple we perceive is one with the apple on the table, there is no longer any need for a phenomenal apple.

My point is, what we’ve been calling experience is just existence. We do not experience objects. Objects exists and they are what we are. There is just existence.
Logically speaking, MOI goes in the opposite direction of panpsychism. MOI is a, if you like, a panphysicalism (or panexistentialism).

Thanks. I don’t want to tax your patience. I may have misunderstood when you said that a table’s “relative world is rather dull.” I think you are drawing a distinction between experience as primitive and experience as transactional or relational.

I love to reply.
The apple is not in relation with me. The apple is in relation with my body. As the apple standing on top of the table is in relation with the table.
All objects are in relation with other objects. Being in relation with a given object brings into existence given relative properties. A different object would have brought into existence different properties.
There is no consciousness as something over and the above existence. There is just the existence of objects as they are. A bundle of relative objects is my existence. Another bundle of relative objects is your existence. That’s the idea. There is no consciousness, just existence.
We’ve been mistaken into believe there is consciousness in addition to consciousness. Why did we do so? Because we assumed that the experience of objects had to be ontologically distinct from the objects and placed inside an object (the brain) with none of the properties of the things we are one with. Thus we invented a ghost, called consciousness or experience, conveniently placed either inside the head or “inside us” (which is a meaningless expression) or inside our interiority (another meaningless expression).

Dr. Manzotti, I’ve given some thought to your explanation, and I hope I can tempt you back for a follow-up response.
I won’t try to find certain sorts of objects that are problematic for your account, as seems customary, because I believe your account can survive such counter-examples—if only because the nature of an “object” is equally flexible for both sides.
Rather, I want to explore the choice you made after you noticed quite correctly how we have “assumed that the experience of objects had to be ontologically distinct from objects and placed inside an object (the brain) with none of the properties of the things we are one with.” At this point we are reconsidering the idea that there is a “subject,” which has experiences, and an “object,” which is experienced. You find it metaphysically parsimonious to collapse the two, so that there are only objects, which exist in relationships, such as “this apple” for “this body.”
Why, at this juncture, did you choose to build your explanation on objects? This threatens to point outside the relationship you are trying to convey, back toward an older Cartesian concept.
It might have been equally possible to rest your discussion of relationships on “subjects.” Of course, this would be to take the other side of the Cartesian dichotomy in an attempt to overturn it. Perhaps we had better be done with both terms altogether, and go with something like “process” or “occasion”!
But as a starting point, the supposition that the apple and I are both subjects seems equally compatible with your innovative approach, and for nodes of existence such as ourselves, it might be more approachable. Had you given thought to this option?

I must make a belated addition to my question about awarding ontological significance to “objects.” You explained at the very start of our exchange that “There is just the world taking place as a bundle of events/objects.” Here you used “events” as if it were interchangeable with “objects.” To me this suggests it might make equal sense to talk about “mind-event identity.” But since we tend to associate objects with passivity and the possibility of an independent or isolated existence, while on the other hand we associate events with activity arising from relationships, the latter word seems more promising for a post-Cartesian view.

Hi AJOwnes again,
You made two excellent points (why not go for a subject-only ontology and why not consider mind-event ontology). The two points are apparently different but share a common root. Let me address them orderly.
1. If everything is an object, why should everyting not be a subject? Are idealism and materialism not symmetrical? My answer is a definitive no. The reason is that the world of appearance (experience/ideas/etc) is defined parasitically on the word of matter (substance/whatever).
Moreover, experience requires an experiences. So if we want to have a flat ontology, we need an ontology made of something that exists by itself, i.e. substance or matter. Experience is not a substance. this is in a nutshell, but I am sure you can get the gist of the argument.
2. Why not a mind-event ontology rather than a mind-object ontology? For me it’s fine. It might also be an mind-actual occasions ontology. I use the word object for a series of reasons. But my objects are not naive objects, they are relative objects in act. So I agree with you.
Finally, the common ground is that by adopting a relative actual objects ontology, there is no need of experience, appearance, relations, etc.

Thank you, Dr. Manzotti, for an informative reply.
When you say “we need an ontology made of something that exists by itself, i.e. substance or matter,” I think of this “by itself” thing as existing, as it were, in itself as well as for another. Whether we call it “substance or matter,” or whatever, its existence for another is what explains consciousness, but its raw existence in its own right is the prerequisite for consciousness.
This differs from relational theories, such as that of Rovelli, where the relationship itself constitutes the raw existence of the thing. But if I understand you, it doesn’t necessarily assert an ontology of “naive” objects in their own right, as with Object-Oriented Ontology. Rather, it asserts an ontology of some almost ether-like medium, required for relationships, or patterns of information, to be expressed or instantiated as “relative objects.” As we move beyond the explanation of consciousness and into an underlying ontology itself, is this what you have in mind?
You seem to agree that we could talk about objects as events instead, but “for a series of reasons,” you prefer the word “object.” It’s these reasons that interest me. Personally I prefer the word “event,” as suggestive of a different kind of relationship more suited to the concerns of the 21st century than the “objects” dear to instrumentalist modernity.

From the posts here, Mind Object Identity seems to be highly focused on ontology, and more specifically objects. Properties and perceived properties only seem to come up for discussion when humans imagine novel combinations such as a chimera. I wonder how Manzotti would react to experiences like the hot hand / cold hand experiment I discussed on my blog. It seems to me that MOI needs to add (or clarify) that an experience can be an object as relating to a specific part of a body, not always the whole body.
I find a lot to like about MOI. I’ve thought for a long time that redness is a property of apples and other relevantly structured surfaces, for example. It doesn’t hurt that I have a very permissive ontology of objects, events, processes, properties, and relations.

I agree with you! When I refer to the relative nature of objects, using the body as a whole is an oversimplification. Of course, different parts of the body act as as many bodies.
About the cold/hot hand experiment: if the state of a part of the body changes, the relative properties of objects change too. Thus the same object may have a relative temperature for on hand and another relative temperature for another objects.
The advantage of placing relative properties in the world is that we do not have to invent invisibile subjective properties inside the brain.

Suppose you read Ariosto’s renaissance poem “Orlando furioso” and you read of the mytical beast called hippogrif (the head and the wings of an eagle and the body of a horse). You get what it means because in your life you encountered eagles and horses and the poem pushes you to allow eagles and horses to produce an effect together.
What is a story then? It is a physical objects that allows other physical objects in people’s lives to produce effects together in novel combinations and thus it is a physical object that allows to new objects to come into existence.

Of course, MOI admits the possibility that different subjects sees colors differently, because colors are relative to ONE’S BODY (but not to him/her). If bodies are different, for instance because one is tetrachromat, then relative colors – still physical – would be different too.
As in the case of relative velocity. If you move at different speed, the relative velocity of other objects will change accordingly.

Consider this. Relative velocity. Take a body O in space. And now take another body B approaching O at a given speed. Does O have a relative velocity C to B now? Yes it has! Where and what has C? O of course. It’s O’s relative velocity to B. Now crush B. Does O still have the velocity C? No, it hasn’t.
Now, take O to be the external object, C to be any relative physical property of O, and B to be one’s body-brain.
And now you will see that the fact that there is no need to place the subject where the brain is. Nor to give the brain mystical superpower such as “projecting objects where they ought to be”. What does it mean that the experience of the tree is located where the tree is not? In which mental space is the experience located?

I never have seen a need to place the subject in the brain. The subject is simply another part of the model of reality the brain has created. The brain in conception is, of course, another part of that model. The idea that it might be where the model exists is a hypothesis of that model which works well for most purposes – we might monitor brain waves to determine if a person is conscious, for example.
Locating the subject outside the model isn’t possible because the foundation of the model is differentiation of physical body (of the model) from the external world (of the model) in order to be able to act in the world; hence, the evolutionary purpose.

It is a concrete physical model that mimics reality by creating an analogue or simulation reality where all the objects interact.

It seems hasty to me to dismiss models. A scientific theory is a model. Your hypothesis is a model that you’re arguing for. My knowledge of where my fridge is, and what I think is currently in it, is also a model. Even my knowledge of my own body is a model.
And I’d argue that my ability to remember an elephant, even though there isn’t one in front of me right now, utilizes a model. Yes we can see that as a relation between my body and an elephant I once encountered, but the fact that the elephant can still affect me requires something in the brain to preserve those effects. I think the right name for that something is a “model”.
Of course, the physical manifestation of these models in brains is far from obvious. They seem like a disparate network of associations, dispositions triggered on certain stimuli, pattern completions. We could also regard them as complex decision trees with crosstalk between them. You could say all of that isn’t a model, but then I think we need another word to describe those dynamics.

Let me quote something I wrote a few years ago:
“The brain, of course, is all about seeing relationships, identifying differences and similarities. It does this with learning and memory. What our senses present to us may not be veridical but the relationships in what is presented must be veridical or we could not interact consistently with the world. When people are fitted with prism glasses that turn everything upside down, they learn in a few weeks how to interact with the world using completely upside-down input. This is possible because the relationships between the objects are relatively the same. Regularity and consistency in the world still exists and the brain can learn about the regularity and how to operate with it.
“Perceptions are not exactly veridical, but our understanding of the world still is to a degree veridical because we learn about relationships between the objects of the world. Evolution selected for perceptions, which are not veridical, and a general-purpose brain that can detect relationships in those perceptions. I think perhaps part of the so-called hard problem of consciousness comes exactly from this disparity between nonveridical, somewhat arbitrary, perceptions and the more veridical understanding of relationships. When we look at the world, we do not really see it, but we do see relationships in it. That makes the world sometimes seem like a simulation and it makes us wonder where the simulation comes from”.

If I’m not mistaken here, Manzotti’s MOI is a highly complex extended version of Rovelli’s RQM. Correct me if I’m wrong Riccardo.
RQM extended would mean that there is an interaction between one object, the brain and another object, the apple. The variables of these two systems take value only at the interactions and the values they take are only relative to the other system affected by the interaction and the system that is affected by that interaction is the brain and the affect of that interaction is what is known as consciousness.
Where Manzotti’s model breaks down is that he does not recognize that consciousness is “now” an emergent system as a result of that interaction just like H2O is an emergent system as a result of taking on the values of one oxygen atom and two hydrogen atoms.
There is a great deal of obfuscation occurring within his explication of the subject material, and I think this muddy water is an artifact of conflating the brain with mind. Can there be a full accounting of mind and/or consciousness in a physical framework? Absolutely!!! Ideas are physical structures, the only question that remains unanswered with MOI is what is the physics of that physical structure. The only physics that is tenable is quantum.

there is an ontological problem here. Several actually. They are not your fault but it’s the state of the debate these days.
People use “emergence” as an ontological scapegoat to have something unexpected popping out. First and foremost, the notion of emergence is faulty. It does not explain anything. As long something is truly emergent, it’s nothing short of a miracle (brute emergence is akin to dualism). A truly emergent level is just like the immaterial mind. It’s something alien to the underlying level of reality.
On the other hand, it is not brute emergence, it is no longer different from the underlying level of reality, and thus it wont’ do what emergentists hope it will.
Either way, the notion of emergence is a recipe for disaster.
Secondarily, you want to use emergece as a magic wand and the appeal to quantum magic is just alike. You do not have any sound argument based on real QM formulas. Please don’t take personally, but it’s ages that I hear these vague declarations about QM as the solution. But we simply have NOT ONE REASON EITHER EMPIRICAL OR THEORETICAL (pace Penrose and Hameroff) as to why a quantum level should be any closer to what we know as our existence (or experience).

To my way of reasoning it is not at all unexpected; in fact, based upon the empirical evidence that mind is a subjective system and not veridical, one would expect mind to be separate and distinct from the brain. That is of course unless you believe that a single system such as the brain can be both objective and subjective at the same time. And if so, then we truly do have a miracle taking place because its the only system in the known universe that is capable of being both objective and subjective at the same time.

We find a person who has never experienced any hue between 260 and 280, and show him a deck of 35 cards, from which we have surreptitiously removed the 270 card provided by the paint company.

I actually tend to think neural activity is the easier sell here. But it requires considering the adaptive function of that activity.
Consider the following spectrum map.
There’s nothing in those specific wavelengths that determine when we transition from blue to green to yellow to orange to red. The wavelengths we receive from an object are due to the reflective properties of its surface, but nothing about those properties mandate any specific hue.
That’s because color isn’t a property of the object. It’s a conclusion our brain reaches about the object based on those wavelengths (and other factors). The things we see as red or yellow, and the things we see as blue or green, are due to the evolutionary affordances those objects provided our primate ancestors. The sharpest distinctions are for common foreground objects, and the least distinct ones are for hues commonly in the background. (At least for a land animal concerned about ripe fruit.) And the most striking colors are for items with the highest saliency.
Seeing color as a conclusion makes it easier to account for things like “the dress”, or a host of color illusions.
https://en.wikipedia.org/wiki/The_dress
And it allows for the fact that color blind individuals can’t distinguish as many colors. Or that different species of animals have widely varying capabilities when it comes to color discrimination.
I don’t really see any of this as necessarily a problem for your overall hypothesis. Except that simply considering color to be at the object seems too simple.

totally right about everything (actually it was Newton himself who first noticed that the velocity of photons – which was later redefined as frequency – could not account for the wheel of colors as well as for the discontinuity in the spectrum).
but …
first of all I keep talking of RELATIVE properties and I’m not a NAIVE phycalist. This is paramount.
what do I mean?
The naive physicalist believes that properties are absolute. So the property is the wavelength. Which is, say, varying continuosuly from 380A to 750 A. And so, how can a such a simple value explain the color bands, the color wheel, the primaries, and so forth? It cannot of course.
yet this is naive physicalism.
But, starting with Galileo and velocity, physicalism is not committed to such a naivety. We can step forward to what I call contemporary physicalism where all properties are relative. Sometimes the relation is easy to be expressed with a simple formula (as is the case with mass, lenght, size, velocity, frequency, etc.), sometimes it requires to take into consideration a complex interaction with an object that might be as complex as the human visual system.
The human visual system, as complex as it is, is only a physical object though. It does not interpret. It does not create colors. It does not process information in terms of colors. And all of that. What does it do? It allows hues to produce effects. That’s all. As it happens, our visual system, due to its evolutionary history and biological constraints, does not react equally to all changes in the visual spectrum. So, as regards to the effects that a HUE produces RELATIVE to a human visual system, it might well be that HUE 480 and HUE 485 are more different than HUE 600 and HUE 605. Why? Because they are different RELATIVE to their effects, not in an ABSOLUTE and NAIVE way.
Having said that, I insist: neural activity does not have any of the property of colors! How could it be the underpinning of colors? Where are colors in the brain? I don’t see any!

Of course not. That’s because when I watch the data viewer the relevant external color is not the original color, but the screen of a computers. Because the relative object (relative to the visual system) is the external relative object that is impinging with light on the retina. Why should you see the historical causes? MOI is very precise about the causal circummstances that allows you to be identical with previous causes. Not all causes do.

So what? Do you really believe to see a yellowness generated inside the brain? The yellowness does not have to come and go anywhere. The yellowness sticks with the yellow objects.
You may ask: why is that in memory the historical cause seems to be available and with the data viewer it does not? Simply because the causal structure of neurons is different from that of the data viewer. The colors do not stand in the same causal relation with your brain if there is a data viewer in beween.

MOI is not a scientific theory or even a scientific statement regardless of Manzotti’s assertion to tout it as the “ultimate physical model of reality”. MOI is an ideology plain and simple, just like any other ideology. And the predicate concept of that ideology is straightforward; there is only existence as an object relative to another object. There is no consciousness, there is no experience, there are no relationships, there is only existence.
“POOF”… just like that, the hard problem of consciousness disappears because THERE IS ONLY “EXISTENCE” AS AN OBJECT IN RELATION TO ANOTHER OBJECT. Cool huh……
A few other ideologies come to mind like Rupert Spira’s claim to fame: “I am the nature of being” or, an idealist’s declaration: “Consciousness, it is all there is” or, the christian evangelical’s assertion: “Jesus, it’s all there is”.
I mean, after I smoked a couple of bowls of ganja last night I was able to really groove on the profoundness of the MOI model. No, wait…… maybe I grooved on “I am the nature of being”. No… wait; now I can’t seem to remember, maybe it was Kastrup’s mind-at-large. Maybe I need another bowl…..

Instead, you babble hypotheses and phrases that are metaphysically inconsistent and that seem better to you only because you have repeated them so many times that you have become accustomed to considering them true. You don’t even realize, like fundamentalists, that you are no longer capable of reasoning.
But it is significant that you say that MOI is an ideology.

Dan Dennett in his 1991 book described how the colors of flowers and insect perception co-evolved, with the flowers signaling to the animals they have a symbiotic relationship with for cross pollination. Fruits have a similar relationship, advertising their readiness to be consumed (and their seeds spread) by their partner species like primates.
Thanks for the book recommendation! Looks pretty interesting. Something I’ll have to keep in mind.

One big piece of evidence for co-evolution is specificity of wavelengths, such as bees able perceive patterns in flowers that only appear if you can see into the ultraviolet range.

Bees and humans reacts to different clusters of color-related affairs. ie. Colors have different relative properties thanks to our bodies.

Martin,
Is this the unsubscribe for email notifications? It’s the standard WordPress.com functionality. Unfortunately I don’t have any ability to do it on my end. You might have better luck just going directly to the site: https://wordpress.com/email-subscriptions/?option=comments

Thanks. I appreciate your discussions and I’m grateful you liked my blog, but I only wanted to get email notification of any responses to my post.
I used the link and did UNFOLLOW. I can check your blog directly anytime I want to read a discussion. Fascinating posts, but many lean heavily to theory.
When I said “you” are selling data, I meant WordPress, whose link I was trying to use. They have begun to glom other aspects of the web — for example, my web site’s host now uses their software, replete with tons of options but also including forced changes to “skin” without due notification or choices.

Quick question. Have you read anything to suggest that the range of wavelengths available to all organisms might be limited by the requirement that detection in a wavelength requires a suitable chemical that can be manufactured by a living organism and is able to react to the wavelength?
Actually before I posted this comment I found a Quora answer that seems to address this:
Why did all animals evolve to see around the visible light part of the spectrum?
This is the range of wavelengths that the laws of physics and chemistry dictate will react with the types of molecules that biology is made of, enable detection mechanisms to evolve.
Anything much shorter, into the UV range, and the energy levels rises rapidly to the point where the incoming photons start smashing biomolecules apart, and anything much lower, into the infrared and the energy drops too low to trigger reacts in biological molecules at all.

It makes sense that ultraviolet and shorter wavelengths are problematic because it’s ionizing radiation. Although it’s worth noting that many insects see into the ultraviolet. Their short lives might make them less vulnerable to the effects.
But in terms of the upper bound, I think I read somewhere that biology focuses on the range it does because that’s where most of the radiation is in our environment (under our star and within our atmosphere) and so most of the easily available information.

If we had evolved under a red dwarf, we might see more into the infrared. There are Earth animals who can see at least some infrared. Vampire bats is an example that comes to mind.
All that said, I haven’t studied this carefully.

Both ultraviolet and infrared begin just at the edge of the visible human spectrum so it might be that the range for other species is just a tad broader than the human range. It’s amazing, however, how little of the EM spectrum is visible to humans. It would be interesting to see what the magnetic field looks like to the birds who can see it. Does it look like a weird color or black lines or what?

Apparently humans don’t see UV because UV rays don’t pass through the cornea whereas in some animals they do. Some humans who have had their lenses surgically replaced are actually able to see UV. My guess is that the pigments picking up blue/violet must also react to UV. It is just that it never reaches the retina in normal human vision. Also, the UV that a cat sees, for example, is just slightly shorter in wavelength that what humans see.

It sounds like it might be a sort of filtering thing, altering the acuity of the portions of the visual field depending on the magnetic fields variations. (The images imply brightness, but the linked paper mentions acuity.)

what is an interpretation in a physical world? it is a different way for different systems to react to the same circumstance.
You can’t say that colors are interepretation because interpretations aren’t colored.

Hello Riccardo,
Apologies for the late comment in the Q & A, and I am sorry if any commenters came off as rude or abrasive. I read your paper in full, and it seems to me that the chief difference between your account and standard direct realism is the relativity hypothesis. It’s this criterion which is key, and which helps avoid the need for disjunctivism. I do think your criticism of representationalism or indirect realism, namely the issue that brain properties and experiential properties are radically unalike, can be solved however. But before I get into that, I have some comments/concerns about the mind-object identity theory:
1. My first thought is that while technically your theory isn’t panpsychist, in the sense that it does not suppose that mental properties are fundamental (or even real), it is still profligate in its attribution of classical experiential properties (aka phenomenal character) which you attribute to object-object relations. If what we traditionally call phenomenal experience is just a matter of being in the right physical relation to an object, then any physical system will have the kind of qualities that we traditionally hold exclusive to the human mind. From my table’s point of view, it too “sees” the chair in front of it etc… This isn’t necessarily a critique of your theory, however.
2. The first point is further exacerbated when we take into account hallucinations, dreams and other non-sensory experiences. You claim that this can be accounted for by incorporating temporal and spatial extension into our account of object-object relation. However, in allowing for arbitrarily large amounts of spatial and temporal “drift” in object-object correspondence, we have now opened up a can of worms. My criticism in my first point was that basically any physical system of objects will instantiate human-quality “experiences” (if we wish to call it that). But now the problem seems much more severe. If me dreaming up Harry Potter is actually a super complex system of existing spatiotemporally scattered physical parts that happen to coincide in the form of a physical system (which we call my dream), then the matter of object-object relation seems totally arbitrary.
Basically, every object within a certain light cone is in some kind of causal contact with another kind of property, object, or object-part. So if you allow the kind of object-object correspondence that would have to take place in a dream, then it would seem that any physical object would instantiate a veritable infinity of possible object correspondences (which we traditionally call experiences). That’s profligacy to an extreme in my view. Any restriction on object-object relation that might attempt to alleviate this issue, on the other hand, is in danger of coming off as completely arbitrary.
I think there are additional issues which 2 evinces that go beyond profligacy as well, for example issues having to do with the specificity and regularity of human experience (or at least what we call experience). If 2 is correct, then basically any conceivable system of object relations is being instantiated in our universe. But the system of object relations that we are acquainted with is highly irregular, specific, unified, and not at all arbitrary in that sense. As the objection in 2 notes, my body was, is, or will be in causal contact with virtually every object in my light cone. The problem is that this kind of extreme kind of distant causal contact seems to be sufficient to account for object-object relational correspondences on your view (in order to explain dreams and hallucinations). And this would lead to a veritable infinity of “experienced” object-object relations relative to my body.
But I (meaning my body) don’t seem to experience a veritable infinity of object-object relations. Furthermore, my dreams (and my experiences more generally) only happen in very specific conditions, according to mechanical regularities that seem unrelated to the kind of object-object relations that you describe, but which seem very relevant to the operation of my brain.
3. What about the existence of “phenomenal character” that goes beyond perception? For example, stuff life emotions, pain and pleasure? These don’t appear to be accounted for in your theory. So at the least we would have to say that your solution is incomplete, unless there’s something that I’m missing of course.
Thanks for taking the time to discuss!
Cheers,
Alex
