Is Physicalism Incompatible with Physics?

Dusty of Sky May 02, 2019 at 22:47 11675 views 156 comments
Physicalism is the idea that nothing exists except for concrete objects in the material world. But physics is the study of the mathematic principles which determine the behavior of these material objects. And these abstract principles (e.g. F=G(m1m2)/r^2) surely don't exist in the material world. You can't locate them under a microscope. So acknowledging that the laws of physics exist seems to contradict the theory of physicalism. Thoughts?

Perhaps our equations are just representations of how we understand what is real. All an equation does is explain a phenomenon or system in a way that we can communicate to others. I guess you could say that the equations ARE the concrete objects, just broken down in a way we can understand them.

Ideas are still Nouns. If you think about it further, aren't all nouns ideas? My cat exists outside of my mind, but I can only observe him from within my mind. I can tell you his name, and you may be able to identify him. My cat's name (Rico) is the equation and my cat is the concrete object. Is it not correct to say that my cat is Rico? The molecules that make up his cells that make up his body are certainly more complicated than that, so if you want I could go into more detail about his features and personality and chemical makeup. You could say something like Name+Genetics+Experience=Rico. That is a simple albeit relatively accurate formula. The more complicated the formula, the more accurate it seems.

I've never attempted to explain my cat as an equation and I don't know how I feel about doing it either. Regardless, I've always seen language as the bridge between what is real in our minds and what is real in the outside world. I consider equations a kind of language. Language can be broken down to the vibrations of your vocal cords to make different sounds. That sounds like something that can be watched under a microscope to me.

Reply to TogetherTurtle Accepting all of that, the pertinent philosophical question would seem to be: "Then why the hell do you have a cat?"

Seriously, though, it depends on the kind of physicalism we are talking about. Regarding the OP Reply to Dusty of Sky I doubt many physicalists, or any sensible physicalist, would claim that nothing exists except "concrete objects in a material world" since elementary particles are not, according to current physical theory, any such thing; they are fields or waves or intensities in a field. On that conception of the physical, why could ideas, equations or theories not also be such?

This reminds me of Gilbert Ryle's example of a foreigner visiting Oxford and remarking that he had seen the colleges and the libraries, but was wondering where the University was.

So I think one approach for a physicalist here is to say that the laws of physics aren't some additional thing that exists beyond what is observed. Instead their existence, if it is that, just is in the way that those observed things are organized.

(As it happens, Newton's Law is no longer considered to be one of those abstract principles since it's been superseded by GR.)
Dusty of Sky May 03, 2019 at 02:07 #285066
Reply to TogetherTurtle If I understand your cat analogy correctly, you are saying that just as you can represent a complex organism (your cat) with a simple name (Rico), you can represent an enormous amount of physical phenomena (for instance, all the gravitational activity in the history of our universe) with a simple equation (F=G(m1m2)/r^2). So the law of universal gravitation is not something abstract which exists outside of the material world. It's just the name we use to designate the sum of a particular variety of phenomena that occurs within the material world. Please correct me if I misunderstood you.

But I think there's a serious problem with your argument. When people refer to laws of physics like gravity, they are not referring to the sum of a particular sort of phenomena. They are referring to a principle which they understand to govern the material world. If we use your definition of physical laws, then the laws will lose their character of necessity. If the law of universal gravitation just refers to a type of movement, then there's no reason why objects of mass should necessarily attract other objects of mass. Laws of physics would cease to be laws and become mere description of the past. And if gravity is just a simplified description, then I have two questions. 1) why have all objects observed in all controlled experiments always obeyed the law of gravity (as well as every other well established law of physics)? and 2) why should objects continue to obey the law of gravitation in the future? If it's just a description of past phenomena, then perhaps I'll suddenly float up into space. There's no good reason to think I won't unless we understand the gravity equation to refer not to a concrete object, but to an abstract principle which governs the physical universe.

Reply to Janus I'm using the words physical and material interchangeably. So if elementary particles aren't concrete objects in the physical world, then how are they physical? They can't be abstract objects in the physical world. So they're not in the physical world. But if they're not in the physical world, which I understand to include all physical things, then they are not physical things. And isn't the core tenet of physicalism that only physical things exists?

Reply to Andrew M I think my reply to TogetherTurtle basically covers your argument. If the laws of physics are just descriptions of the way things happen to be organized, then they are not laws. And if the laws of physics aren't actually laws, then why does the universe obey them. It can't be random.

Reply to Valentinus I agree. For instance, if you smell roses, does that mean your neurons smell like roses? Obviously not. So how can you neurologically define the smell of roses? You can't. All you can do is point to the spots on your brain that light up when you smell roses.

Physics is physical theory, and not all of what is material or physical in the ordinary sense of those terms is describable or explicable in those fundamental terms. Which is to say that disciplines like geology and biology would become unintelligible if you tried to express our understandings of them in terms of QM or Relativity.

But it doesn't seem to follow that we cannot consistently and coherently say that the entities that are studied in the disciplines of biology, and geology are ultimately constituted by elementary particles or fields. Those entities are complex structures that we think are constituted by, but are not reducible to, or "nothing but" those fundamental entities.

Right, we may be able to show that there are brain processes which correlate with cognitive events, but we can never, it seems, definitively show that the latter are reducible to the former. There would not seem to be any contradiction involved in saying that the latter are constituted by the former, while acknowledging that there are emergent properties which cannot be coherently and comprehensively understood in terms of the former, though.

Reply to Janus I agree with all of that. But don't physicalists believe that everything is reducible to physical entities and nothing else exists?

Reply to Dusty of Sky If you are composed of neurons or cells or both, why would that entail that it should be necessary that they experience what you experience, if experience is an emergent property of complex biological systems? Or even with the philosophical notion of pan-experientialism where experience is fundamental (see Whitehead's Process and Reality), there is no claim being made that experience is the same, or even of the same kind, for complex and simple entities.

Indeed they do. The key word is 'reducible to'. Another way of putting it is that such things as consciousness, ideas, thoughts, and so on, supersede on the physical (per the SEP entry on physicalism. If someone doesn't hold that, then they're not physicalist, because physicalism is above all monistic, i.e. there is only one basic category of stuff, and that is the physical.

One way to argue against that, is to say that such capacities as rational inference and abstract thought are of a different order to anything disclosed by the study of the physical. Or, put another way, there's no coherent means to get from the laws which govern physics and chemistry, to those which govern mathematics and language, as they belong to a different domain. Nor will any amount of neuroscience reveal anything about the foundations of logic, so to speak, as it inheres solely in the relationships of ideas, not on the relationships of physical substances.

That suggests a form of dualism, which I'm willing to defend, if need be.
Janus May 03, 2019 at 02:45 #285081
Reply to Dusty of Sky Again, I think it depends on the physicalist. There is a philosophical position called Eliminative Physicalism, which might be taken to be saying that. But on the face of it, to say that while adhering to the common notion of "physical" (meaning something like 'sensible' or 'able to be sensed') would seem to be such a blatant contradiction of modern scientific understanding and commonsense as to suggest that even the eliminative physicalists must have something else in mind, since they are obviously not stupid people (for example, see the Churchlands).

The best plan, if you want to critique them, would be to study their works to ascertain just what it is they are saying. There are some on these forums who go on endlessly about how ridiculous and deplorable these eliminative physicalists are, and yet when you question them, you discover that they have not read any of their actual works. They just rely on secondary articles and book reviews from those who share their own prejudices. This is nothing more than confirmation bias at work.
Dusty of Sky May 03, 2019 at 03:18 #285086
Reply to Janus If I understand your use of the term 'emergent' correctly, you mean that the whole which emerges is somehow greater than the sum of the parts from which it emerges. So you could not come to an understanding of the smell of roses just by analyzing each individual neuron involved in producing the olfactory experience. But is it even theoretically possible to understand experience using neurology? A painting is greater than the sum of its paint droplets. But that's because, along with the individual droplets, there are also geometrical relations between those droplets. And we understand how geometric principles transform individual points into complex shapes. But what sort of principles could we use to correlate simple neurological activities with the complex experiences they supposedly produce? Maybe I'm just not imaginative enough, but I don't see how that's possible. And if the emergence of experiences from neurons doesn't occur in accordance with clear principles, then it seems like the word emergence is just a more mundane sounding substitute for 'infusion by the holy spirit' or 'transcendent awakening.'

Regarding physicalism, I am not arguing against any particular eliminative physicalists. Maybe physicalism, like humanism or conservatism, is one of those philosophies which continues to evolve and branch out. In that case, there doesn't seem to be any point in critiquing it, since its defenders can simply claim 'not all physicalists think that' or 'physicalists haven't believed that since 1917.' But the definition of physicalism I was using was the simple one that you get in encyclopedias, namely that everything is ultimately reducible to physical entities.

I don't claim that it will ever be possible to precisely correlate brain activity with complex experiential processes. But there does not seem to be anything in principle wrong with the idea that there may be neural processes correlated with all experiences. We just have to decide which, on the available evidence is more plausible: that there are neural processes correlated with experiences or that there are not, and more strictly that there are neural processes correlated with all experiences or not.

So ,emergence is one possible explanation and "infusion by the holy spirit" or 'transcendent awakening" might be others. How will you decide as to which is the more plausible?

In regard to your definition: what does "reducible" here mean, though? Does it mean explicable? Nothing but? And what is your definition of a physical entity?
Dusty of Sky May 03, 2019 at 03:48 #285095
Reply to Janus Regarding neurons, I agree that we should try to find the most plausible explanation for experience. Neuroscience seems to be a better candidate than vaguely defined notions of spirits and souls. But I still think we can do better. The P-Zombie and Mary's Room thought experiments demonstrate what to me seem like serious problems with the idea that all experiences are caused by neural processes. However, I'm open to the idea that all experiences are correlated with neural processes.

Regarding physicalism, I'll try to give adequate definitions of the terms you asked for. By 'reducible', I mean that nothing in addition is required to explain. So I mean both explicable and nothing but. By physical entity, I mean fundamental particles and the composite objects that are made of fundamental particles. Maybe space-time should also be included as a physical entity.

What about physical properties that are not themselves entities; like wetness for example?
Dusty of Sky May 03, 2019 at 03:57 #285100
If you mean wetness phenomenologically, then it's definitely not a physical entity. If you mean liquidity, then wetness is reducible to the composite state of physical entities.
Janus May 03, 2019 at 04:04 #285105
Reply to Dusty of Sky Why should you think that wetness, as liquidity, is "reducible to the composite state of physical entities" whereas, phenomenologically speaking, it is not? Can you explain how liquidity is reducible in the way you say it is?

The other point is that a physicalist, in order to be counted as any kind of physicalist, does not need to say that wetness, considered either way, is "reducible to the composite state of physical entities", but might rather say that it is an irreducible emergent physical property.
Dusty of Sky May 03, 2019 at 04:11 #285107
Reply to Janus Perhaps I should brush up on my physics, but I think that the liquid state of matter is fairly simple to define. It corresponds to certain pressures and temperates. And if something is liquid, that means that it will assume the shape of its container. It has a fixed volume. And it will behave according to the laws of fluid dynamics. I think physics gives us a fairly comprehensive definition of liquidity. Phenomenologically, wetness is the feeling that something is wet. It doesn't exist in the object which we perceive as wet, but in our own consciousness.
Janus May 03, 2019 at 04:16 #285109
Reply to Dusty of Sky But you still have not explained how a composite of microphysical entities produces the phenomenon of liquidity. I don't know if there are any comprehensive explanations of this, but of course I am not denying such an explanation is possible, even if perhaps only in principle.

When it comes to the phenomenological feeling of wetness; why say that is "in our own consciousness" rather than saying it is in the physical or material interaction between liquids and sentient bodies?
Dusty of Sky May 03, 2019 at 04:24 #285113
Reply to Janus I don't know enough about physics to say for sure. But from what I remember, the four states of matter are clearly defined. They don't have any mysterious emergent properties. Solids have fixed shape and volume, liquids have fixed volume but unfixed shape, gasses have unfixed shape and volume, and plasmas are ionized gasses. Am I missing something?

Nothing that we experience is the direct representation of an interaction between our bodies and the world. First, it gets processed through our brain (and perhaps a non-physical mind as well). So the phenomenological feeling of wetness can only be a mediated result of the body's interaction with a liquid.

To be sure there are neural processes within the body that, along with physical contact with the liquid give rise to the feeling of wetness. What is it that feels wet, though, apart from our bodies or parts of our bodies? Our brains don't feel wet, in fact we don't feel our brains at all. If I dive into water my whole body feels wet. If I dip just the tip of a finger into a liquid it is only my fingertip that feels wet.

Our minds coordinate visual and bodily sensations to form a distinct impression of body parts like fingertips. And when one of our body parts is wet, our minds associate the sensations of wetness with the body parts from which they originate. But the feelings themselves are in the mind. If you jump in pool without a brain, the feeling of wetness will not occur. In the context of our current argument, I'm using mind and brain interchangeably.

Aren't you relying on science to tell you all that? I can't tell whether you are accepting or rejecting physical explanations of the experience of wetness.

You might want to say that all of our experience is in our brains, but if all of science is also only in your brain then how would you know what the notion "in our brains" even means?

Perhaps you mean to say that the models of experience that are created, including the models of the brain itself, are in our brains, but that would be to suggest that there is a real brain that corresponds to our models. How could you know that?

If there were a real, physical brain that corresponds to our models, why would there not be a whole world of other real physical objects which correspond to other models, which are not in our physical brains?

The corollary of this kind of thinking seems to be a weird kind of dualism like Descartes'. The you have the problem of how something physical could interact with something non-physical.

I meant that while gravity is a real thing that we can observe, the name "gravity" simply tells me what you are talking about. It's a useful short term for when not everyone at the dinner table understands math. So the name "gravity" only exists within our minds, but the actual phenomena is what is undeniably real.

Well, undeniable to an extent. You mention that these names turn into descriptions of the past, and you would be absolutely correct. After all, we can not know and study the future. Rico may one day have white fur instead of orange, and while I will obviously be confused about how that happened, you can't blame me for thinking he was orange.

Essentially, I see science as a whole as reverse engineering nature. No one can tell you if you are right in science. Sure, a supervisor or respected elder may tell you what they know, but there is no answer key on the field. Gravity may be a whole lot of hoo-ha. I don't think it is, I hope it isn't, but if you think it is, you still have to explain everything gravity does. While flat earthers have more of a conundrum than a theory, they are still at least attempting to explain what they see.

So, what is real is the phenomena. Objects are naturally drawn toward each other. My cat is orange.

The name can be simple or complex. Gravity can be F=G(m1m2)/r^2 or just simply gravity. Rico can be Rico, or the sum of his genetic code plus his experiences of the world, plus his name, etc.

However, different people explain things in different ways. To a flat earther, what you call "gravity" is simply flat Earth falling at 9.8m/s. You can tell him his definition is wrong, and I would agree, but he is still talking about the same thing we all experience.

What we observe could change tomorrow and never change back. As so, I believe our names and definitions should change with them. Of course, I don't think gravity is ever going to change, but we can only know the past and use that to predict the future.

The you have the problem of how something physical could interact with something non-physical.


The problem of how the physical interacts with the non-physical was solved a long time ago by Plato, through the introduction of a third principle, the medium between the two. This is called "Plato's tripartite soul", mind, body and the medium spirit. Look it up. Descartes did not adequately describe this principle and so reintroduced the problem of interaction to anyone who does not look beyond Cartesian principles to understand dualism. However, anyone who has studied dualist principles with more effort will know that interaction is a non-issue, which was resolved for western philosophers prior to the life of Jesus.

Yes, they do exist in the material world, or senses wouldn't be able to sense them. Symbols are just manipulations of material. Their conceptualization is processed, transmitted, received, memorized by way of chemical and energetic functions within physical locations--brains. That we perceive them as non-physical doesn't affect their being physical or not. Perception is also a physical and energetic exchange between the senses and the brain.

I partially accept physical explanations. We know from experimentation that experiences correlate with brain states. But I'm not a Cartesian dualist. I think experiences like wetness or surprise or the color blue have real substantial existence. I think it's self evident that they do, because we experience them. I think that physical objects only exist in the sense that they can explain the world we experience. And physical explanations are compelling enough that I think it's pretty safe to say that there really is something (let's call it OR for objective reality) corresponding to our concept of the physical world. But we don't what OR is. We only know how it affects our experiences. I'm drawing the same distinction that the Orthodox Christians use when they talk about God. They can know the energies of God, but they can't know his essence. So when I talk about the physical brain, I'm just referring to the causal source of experiences. I'm not specifying what the nature of the source is. And I'm also drawing the Aristotelian distinction between different types of causes. The physical brain might be the efficient cause of our experiences, but I don't think it's the material or formal cause. The material causes of experiences are not neurons, but the components of experience itself such as colors and sounds and feelings. And the formal cause of experience, I think is best described by what Kant referred to as the schemata: the functions by which our manifold of sensations are arranged according to space, time and the Categories. I'm happy to defend and elaborate upon my own ideas, but I'll just remind you that the original purpose of this post was to challenge the idea that everything that exists is physical.

And these abstract principles (e.g. F=G(m1m2)/r^2) surely don't exist in the material world. You can't locate them under a microscope. So acknowledging that the laws of physics exist seems to contradict the theory of physicalism. Thoughts?

D.M. Armstrong developed a physicalist metaphysics that is consistent with these abstract principles. In a nutshell:

Everything that exists is a state of affairs (SOA). An SOA is composed of 3 types of constituents:
a particular, its properties, and its relations to other SOAs. The gravitational force between 2 objects is a relation between those objects (states of affairs) that is describable as a function of the internal properties of their respective masses and of the distance between them.

The relation described by the gravitation equation does not exist independent of the objects; it exists only in the objects (states of affairs).

Physical laws are expressed as mathematical equations. So they are not merely descriptions of the past but are also predictions of the future. Scientists observe structure and patterns and hypothesize testable laws and explanations. That seems to work pretty well.

So it appears you are asserting a Euthyphro-style dilemma. Either the universe obeys a law external to it or else there can be no law (in which case we should expect a disorderly universe). Would that be a fair description?

the laws of physics are just descriptions of the way things happen to be organized, then they are not laws. And if the laws of physics aren't actually laws, then why does the universe obey them. It can't be random. What are the odds that every physical object, in the absence of laws, would always act as if it were governed by laws? Statistically infinitesimal, I would say.


You're begging the question here. Why would you say "it can't be random", what is preventing that from being the case? You've already presumed there are laws which prevent certain things from being the case by claiming that particles cannot randomly act in the exact manner they do. If there are truly no laws at all, then one of the things that can be the case is that all particles simply behave the way they do for no reason at all. With no laws, what is there to prevent them from doing so? Also, with no laws, there is no such thing as statistical liklihood either, so you can't even say it is unlikely.

I wasn't talking about a totally unordered universe. I was talking about a universe which was ordered the way it is for no reason at all. I'm saying that that to presume order must have a law enforcing it is to presume the natural state of affairs is disorder, which is question begging, presuming we already know enough about fundamental particles to know they cannot become ordered without some force compelling them.

I agree that in a universe without any perceived order, there could be no individual thing, but that does not require such order to actually exist, nor does it require such order to have been enforced by laws external to that which is thus bound.

Consider all that happens when teaching a physical law:

i) We write a statement which expresses a physical law.
ii) We demonstrate the meaning of the written statement by performing an experiment.
iii) We summarize the result of our demonstration: "Performing action U in state A resulted in state B, in accordance with the law"

According to realism, we've demonstrated the truth or coherence of the law as well as the meaning of the written statement, but the meaning, agency and whereabouts of the law itself mysteriously lie elsewhere.

In contrast, according to anti-realism our demonstration is part of the very meaning of the physical law. That is to say, the physical law is in part an anthropological description of what physicists do in certain situations to achieve a sense of coherence.

Of course, the anti-realist shouldn't forget the role and responsibility of the environment in the truth of experimental outcomes, that is to say the construction of such outcomes. The difference is, the anti-realist includes the very actions, perceptions and mentation of the physicist as part of the very definition of the physical law he is verifying.

Physicalism is the idea that nothing exists except for concrete objects in the material world. But physics is the study of the mathematic principles which determine the behavior of these material objects. And these abstract principles (e.g. F=G(m1m2)/r^2) surely don't exist in the material world.

If these abstract principles don't exist in the "material" world, then how did they make their way into your post for me to see and read? Is an internet forum with people's ideas that you access via your computer an abstract principle? How did you come to know of abstract principles if not by the world itself, which you call "material" and "physical"?

The problem with arguments like this is because they assume some type of dualism - where two or more kinds of substances exist and are so different that they are incompatible, or unable to interact.

There is no "physical" or "non-physical". Everything is part of the same world, or reality, or substance that do interact. How do you explain your non-physical ideas being put into a physical form for communicating to other minds? How do you get your ideas into other people's minds, if not by your non-physical mind interacting with the physical and then vice versa, when I read your posts?

These terms are incoherent and unnecessary. We can talk about the world without using such terms. Your mind is a representation of the world, and as such mathematics is a model of the world. We could use words just as well as numbers to describe the world and numbers and words are composed of visual scribbles or sounds if they are spoken. How did you come to know the existence of numbers and words if not by using your senses to access the world?

The relation between (or among) states of affairs can often be described mathematically. The point is that the equation is an abstraction, and doesn't exist independently of the states of affairs.

Armstrong is a realist regarding laws of nature. He believes there are actual laws of nature, not just regularities. To Armstrong, "laws of nature are dyadic relations of necessitation ... holding between universals." Where a universal is a "state of affairs type".

Electrons and protons are two different "state of affairs types". Each electron has the property "-1 electric charge"; while protongs have "+1 electric charge." It is a "law of nature" that protons and electrons attract one another because of their properties. This attraction is a dyadic relation (involving any electron-proton pair) necessitated by their properties.

This is not accurate. Physicalism refers to a spectrum of positions, but it is most commonly formulated as a commitment to the claim that everything that exists supervenes (or in some way depends) on the physical, where "the physical" is defined in terms of the ontological commitments required by the physical sciences (whether future or current). Again, there are many nuances on this general theme - perhaps as many nuances as there are physicalists!

Often people who wish to reject physicalism characterize it as a necessarily mechanistic model, which it only is insofar as it is in accordance with outmoded paradigms. This is nothing more nor less than knocking down strawmen.

The interaction problem only exists for those who think of mind and matter as completely different substances. Positing a third intermediary which is a composite of both does not really help, since we have no good reason to consider mind and matter to be completely different substances in the first place.

There is very good reason to consider two completely different forms of actuality, and therefore two completely different substances. These reasons are evident all over this forum in the form of various philosophical problems. Mind and matter are apprehended as completely different. The so-called interaction problem is an argument used against the dualist description, which is to treat these two as different substances. But the third "intermediary" renders this interaction argument as impotent. Therefore dualism remains as an acceptable solution to these philosophical problems.

When something is apprehended as "composite", a proper understanding of that thing requires an understanding of the individual elements of that composition, and the reasons for their union. So it does not serve us in our attempts to understand nature to simply say that nature, as a whole, is a composite, and ignore the fact that a composite is composed of distinct parts, united somehow. The division is evident to us, like the division between past and future, and to ignore the division in order to claim that the two distinct parts are really one, without understanding how the two distinct parts are united, is just a mistake.

To summarize, we actually have very good reason to consider mind and matter as distinct substances. The so-called interaction problem has no bearing. And, if our goal is to understand nature, and nature appears to be composite, there is no reason not to make the appropriate divisions in analysis. So denying the dualist distinctions is just detrimental to the process of understanding.

Not a specific argument, just an observation. I think framing physical laws in that way implicitly assumes Platonic dualism. That is, Platonism assumes there is a material domain and a separate domain of forms. On that framing, subordinating form to matter would imply that physical laws are contingent and nominal rather than necessary and universal - and so not really laws.

But a different approach is to reject the Platonist framing. Instead there is a unitary universe that can be investigated and described in both experiential and logical terms. The universe exhibits form rather than obeying it or creating it as the horns of the dilemma suggest.

In statistics, we collect data about a sample in order to make inferences about the whole to which the sample belongs. For instance, we might survey a sample of coin flips in order to find whether heads or tails is more likely. And unless we are biased in the way we choose our samples, we assume that the more individual samples we take, the more confidently we can make estimations about the whole. If we consistently find that half of coin flips land on heads, we infer that the 50/50 principle applies to all coin flips. It can't just be that the coin flips we came across happened to result in heads half the time for no reason. There must be something about coin flips, as a particular kind of phenomena, that causes them to behave this way. And the same applies to objects of mass attracting objects of mass. If all the objects we observe attract each other in accordance with the law of gravitation, then we conclude that gravitational attraction applies to all objects. It can't just be an arbitrary pattern in the sample we took.

Randomness is the default state of something which isn't governed by laws. Isn't that self evident? If something isn't ordered, we should expect it to be disorderly. Coin flips are random because there isn't any regular principle which determines how we flip them. Conversely, if something does exhibit consistent regularities in its behavior, that indicates that it is governed by a principle. Regarding the second assumption, all we need to accept is that a universe where fundamental particles behaved differently wouldn't contradict anything about logic or statistics.

For instance, it seems to be a property of mass that it causes space-time to warp around it. But I don't think you can just take this fact at face value. Why does the universe exhibit these patterns? It's not logically necessary. Maybe it's physically necessary, but necessity, it seems to me, implies the existence of laws. Something can't just happen to be necessary.

They're not physical objects. How do you resolve this problem without admitting non-physical objects into your ontology?

The fundamental thing to keep in mind is that (according to Armstrong), everything that exists is a state of affairs (a particular with its properties and relations). The properties and relations do not exist independent of the state of affairs in which they are instantiated. We can still think abstractly about properties and relations (through the "way of abstraction"), but these are just mental exercises.

Yes, physical properties are universals, and exist in their instantiations. But it's not quite correct to say that physical laws are functions of properties. Rather, physical laws are relations between "state of affairs types" (SOATs). The distinction is subtle, but important, and it's lost if you conflate properties with SOATs:

We can consider there to be a SOAT for each property (i.e. the SOAs that have property x are a SOAT). But it would be incorrect to say "-1 charge" has an attraction to "+1 charge" - which implies a relation between properties (which is incorrect). Rather, we should say "states of affairs with a -1 charge have an attraction to states of affairs with a +1 charge" - which elucidates the fact that it fundamentally a relation between SOATs (a relation that is instantiated in SOAs of those types).

You asked, "Are these universal natures real things?" If a "thing" is an ontic object, then NO, because a property is not a SOA. Nevertheless, the universal "-1 charge" (which is a universal) exists, as a constituent of certain SOAs.

They are concepts by which we make sense of our observations.

The idea that the universe can be understood is a fundamental presupposition that underlies nearly all human thought, especially scientific thought. If we can't use logic and mathematics to draw conclusions, then science is futile.


I wasn't denying the use of logic to draw conclusions. Science takes empirical observations and uses logic to describe and predict things about the universe. But that's not what you were doing. You said "a universe without logic would be absurd" and "a universe without gravity, on the other hand, is easy to imagine". Neither of those two statements apply logic to empirical sense data. The first simply asserts that logic is a law and that without it the universe would seem absurd to you. The second just declares that you feel you are capable of successfully imagining a thing. I'm asking what either of those declarations have to do with the nature of reality.

That you see logic as a law without which the universe seems absurd, tells us about you, your beliefs and your limits of sense. It doesn't say anything about the universe. That you think you can imagine a universe without gravity tells us about your imagination (or your confidence in it), not the universe.

It can't just be that the coin flips we came across happened to result in heads half the time for no reason. There must be something about coin flips, as a particular kind of phenomena, that causes them to behave this way. And the same applies to objects of mass attracting objects of mass. If all the objects we observe attract each other in accordance with the law of gravitation, then we conclude that gravitational attraction applies to all objects. It can't just be an arbitrary pattern in the sample we took.


This is a common misapplication of probability. I strongly suggest Ramsey's Truth and Probability if you can get hold of a copy. We only presume that something must have influenced a run of 100 heads in a coin toss because we know that normally the distribution would be 50/50. We don't know in advance how we would expect objects of mass to behave, so we can make no probabilistic statements whatsoever about the fact that they all act the way gravity describes.

Randomness is the default state of something which isn't governed by laws. Isn't that self evident?


No. That's exactly the question of the thread. Why would you presume something must be governed externally in order to not be random. Have you seen Lagton's Ant?

Coin flips are random because there isn't any regular principle which determines how we flip them.


No. Coin flips appear random because we don't have the data to determine their path. If we did, their resting face would be entirely predictable.

Interesting, and good to know. But if Armstrong takes the most basic objects in the universe to be states of affairs, then I don't see how he can call himself a physicalist in the traditional sense. States of affairs, as I understand them, consist of relations between abstract entities like properties, relations and particulars without instantiations.

No. A state of affairs is not "relations between abstract entities." Abstract entities do not exist (that would be inconsistent with physicalism). Abstractions are just tools of the mind (useful fictions) they do not actually exist as ontic objects.

Consider actual objects in the real world, such as a rock. Consider the mass of the rock (700 grams). You can't physically separate the rock's mass from the actual rock. There is not a relation between the rock's other properties and the property "700 grams". The rock's mass is an intrinsic property of the rock. You can think abstractly about the fact that the rock's mass is 700 grams, but that doesn't mean "700 grams" exists independently of the rock, or that the rock exists independently of its mass.

Multiple objects can have an identical 700 gram mass: consider all such objects with a 700 gram mass: they can be considered a State of Affairs Type (states of affairs with the property "700 grams mass"). "700 grams mass" is a universal, because multiple objects can have this property.

I hope this helps you understand that a state of affairs is an inseparable package: everything that exists (such as a rock) has properties and relations, but it actually doesn't make sense to say that any of those properties or relations has some sort of independent existence.

A universe that disobeys logic is absurd by definition. It would be circular reasoning to try to use logic to prove itself, and I don't have any other way to prove that it's valid. But if we can't use logic to decide what can and can't be true about the universe, then we can't use anything. Empirical observations are only useful because we can pair them with logic in order to draw conclusions. So what's the point in saying that universe might not actually make any logical sense?

If something happens over and over again in the exact same way, I assume there's a reason for it. And if something happens for a reason, it's not random. If something happens for no reason, it is random. And the ant is governed by laws. They're in his programming. He is determined to move in a certain way, and being determined is the opposite of being random. I take random, undetermined and for no reason to all be synonymous. Whether laws have to be external is a separate issue.

If there is any consistent pattern in the behavior of objects of mass, then I think it's safe to assume that those patterns did not just show up coincidentally. Objects of mass will probably continue to behave as we've observed them to behave in the past, and there's probably a reason for that. Do you even disagree? If you don't think that gravity is a result of an external law, then what is it a result of? A lot of people here seem to think it's the result of the inherent properties of objects of mass.

The very phrase "state of affairs" seems to imply that there are multiple affairs in a single state. I'm not claiming that particulars, properties and relations can exist independently. But in order to explain what a state of affairs is, don't you need to appeal to the existence of its abstract constituents? Just because the abstractions are codependent doesn't mean they don't exist. And I don't think it would be helpful to define existence as being exclusive to things which can (hypothetically) exist independently. Because independent SOAs consist of their codependent parts and therefore depend on them.

In your first statement you treat logic (correctly) as a method of thinking, we "use" logic. In your second statement you treat it as a set of rules which it is, at least theoretically, possible to 'disobey'. This is the problem I'm trying to highlight. Logic is a method of thinking about things (empirical data), which has proven incredibly useful. But its utility derives from the degree of success it has in predicting states of affairs. We can't now turn things the other way around and say that the states of affair are somehow forced (against their otherwise default state) to comply with this method of thinking we made up.

Sort of. The constituents exist (within a SOA), and we can think abstractly about them.

And I don't think it would be helpful to define existence as being exclusive to things which can (hypothetically) exist independently. Because independent SOAs consist of their codependent parts and therefore depend on them.

That's consistent with Armstrong's view. The constituents (e.g. specific properties) actually exist, but only in their instantiations as part of states of affairs. Returning to laws of nature as "relations between states of affairs types" - it shows that there's not actually a dependency on an equation existing as an ontic abstract object. Abstract objects (as ontic objects) are incompatible with physicalism. Constrast this with Platonism, which can assume Newton's law of gravity exists independent of there being objects to which it applies. For that matter, Armstrong would deny the existence of "4" as an abstract object. Rather, there are states of affairs consisting of 4 objects (sub-SOAs), but we can still think abstractly about the universal "4".

That the shirt has pattern X, pattern Y, or some other pattern is a judgment which someone makes. The judgement is made by the person who designed the shirt, that it ought to have such and such a pattern. And so the shirt was made to have that pattern. The pattern exists in the designers mind, and on paper, before it exists on the shirt. It could be imagined to be on numerous different media. So it's actually quite easy to imagine the pattern without the shirt. I don't see why this might be difficult for you.

I don't see how that's relevant. What's relevant is that the concept of "emergence" is such that if something is emergent it is composed of parts. And anything composed of parts is reducible, according to the concepts of "parts" and "reducible". Therefore it is impossible, by way of contradiction, that anything emergent is irreducible. "Emergence" as such is nonsense.

Final cause as described by Aristotle is incompatible with emergence, because it requires that the form of the thing which will come into being is prior in time to the material existence of the thing, as its cause, like an idea, the blueprint or plan for the thing. Final cause implies intention. "Emergence" does not allow that the emergent thing's existence is intentional. Therefore "emergence" is incompatible with "final cause".

Something seems very wrong to me about saying that everything in universe exhibits the same forms for no reason. And if there is a reason, I don't think the reason could be framed as simply a property of the objects which exhibit form. For instance, it seems to be a property of mass that it causes space-time to warp around it. But I don't think you can just take this fact at face value. Why does the universe exhibit these patterns? It's not logically necessary. Maybe it's physically necessary, but necessity, it seems to me, implies the existence of laws. Something can't just happen to be necessary. There must be something else that makes it necessary.


If the universe is all there is, then there is nothing to reference outside of it. The reason why mass curves spacetime, if that's the right question to ask, is to be found by empirical investigation.

Yes, that's the route, examine the mind with the mind. I think your concern about objectivity is misguided though. The mind is what is used to understand both sensible world, and the mind itself. But the mind is present to the mind directly and therefore has direct access to itself, while it only has a mediated access to the sensible world, through the means of the senses. So it only understands the sensible through the means of the principles by which it interprets sensations. These principles are not themselves sensible, they are non-physical, and are only understood directly by the mind. Therefore, all of our knowledge of the sensible world, the physical, is only as dependable, or "objective", as our knowledge of the intelligible world, the non-physical. And it is necessary to conclude that our knowledge of the physical is founded, grounded, and based in our knowledge of the non-physical, so it is impossible that our knowledge of the physical is more reliable, or "objective", than our knowledge of the non-physical.

This is why it is not very wise, and possibly dangerous to dismiss the non-physical as magic. The physicists, and other empirical scientists are using the non-physical principles in their performance acts of prediction. If we want to understand what they are doing in these acts, we must proceed towards an understanding of the non-physical principles. If we dismiss the usage of non-physical principles, and therefore the scientific performances, as magic, this is just a disposition of not wanting to know.

Unless you are direct realist, the pattern is not in the shirt, it is what the shirt is said to have. The designer has the pattern in mind, and makes the shirt as an example, or representation of that pattern. You can see this in all artificial physical objects, cars, planes, building, etc., they are representations of the ideas, concepts, used to construct them. There is a model, a blueprint, design, which the object is made to be a representation of. This is what is in Plato's cave allegory, sensible objects are a reflection of the ideas used to create them. That's how the philosopher comes to understand the reality of existence.

The same is the case with the non-physical principles by which we understand the world. Our minds look at the physical world through these non-physical principles, and until we fully understand what they add or take away from the appearance of the world, we cannot say how the world really is.

No. I must have an image (or instructions) relating to a pattern in order to try to create another pattern just like it. Neither of them are the pattern in some way. They are two different patterns with many similarities.


OK, let's say that they are two different patterns. Whether or not they are similar is a matter of judgement.

Quoting Isaac
Yes. "Exists" is not the problem, "the" is the problem. There's no such thing as the pattern. There are patterns (which are just collections of properties we focus on), those patterns have similarities, that's all there need be to it. We don't need to then reify some archetype.


If there is no such thing as "the pattern", then I see no reason to be talking about the pattern. But if you say that the shirt has "a pattern", then it is you who is trying to reified "the pattern", claiming that it is a real thing within the shirt. I see no principles whereby we might judge something, what you call "collections of properties" as "a pattern". Is any random thing a pattern to you? Can we agree that there is no point in talking about "the pattern", or "a pattern" if you insist that there is no such thing as 'the pattern", and to say that the shirt has a pattern is pure nonsense? if there is no such thing as "the pattern" which the shirt has, it is nonsense to say that it has a pattern.

Quoting Isaac
But a tartan pattern, for example, is just as possible as apples to remove from the world. In fact, before the advent of weaving, there was a world with no tartan pattern. What you can't do is remove all the tartan patterns from the world but leave all the kilts exactly as they were, meaning that the tartan pattern does not exist independently of the thing it is describing.


Talking about the world prior to the existence of some thing, is not the same as attempting to remove something already existing in the world, and then talk about that thing afterwards. These two are completely different. So this comparison is not useful. And since we have no premise to talk about the existence of patterns, as you have insisted there is no such thing as the pattern, we need to establish some premise whereby we can talk about patterns, before there is any point to making a claim such as the one you've made here.

Quoting Isaac
No. A pattern existed in the mind of the designer. A different pattern exists on the shirt. Are you trying to claim that the exact same pattern has been removed from the mind of the designer and placed on the shirt?


No, what I claimed is that a copy of the pattern which existed in the mind of the designer was made on the shirt. So we seem to have agreement here, maybe we can find a starting point. The pattern in the mind of the designer is not exactly the same as the pattern on the shirt. Let's say that there is a pattern in the mind, and there is a pattern on the shirt, and they are not the same, and neither can be said to be "the pattern". Do you agree that the pattern on the shirt is a copy of the one in the designer's mind?

The property of ripeness belongs the the apple alone, not redness.


That's strange I would think that "ripeness" is a judgement made by human beings, and not a property at all. When the banana is ripe for me, it is overripe for my son. Ripeness is not a property at all, it's a judgement, just like good and bad are not properties of moral and immoral acts, they are judgements of such acts. Come to think of it, redness, big, small, hard and soft, and everything that we call "properties" are just judgements made by human beings. When we say that such and such has X property, we are just making a judgement.

Do you think there is, at least in principle, an explanation? And if so where and how is it to be found?


If you mean, do I think there is in principle an explanation for scientific laws, the answer is: I don't think there is. As I said, given that there are scientific laws or regularities or whatever you want to call them, and that we can discover them, then we can discover all kinds of things on the basis of those regularities. But as to why there are those regularites - I think that's actually quite out of scope for science. It seems the typical arrogance of today's world that we would think that this is something that could be discovered. Like the proverbial 'rooster taking credit for the sunrise'.

I suppose from the hypothetical theistic perspective, the reason you can't find the source of order in the world, is because it's not actually there; that nature is organised by principles which don't originate within nature herself. And that does seem at least logical, even though I know it's not a popular view of the matter.

So I'm saying, the question of 'why the universe is lawful' is not so much a scientific as a philosophical question. Obviously whatever philosophy makes of it has to take into account whatever science discovers, but at this point in history, the idea of big-bang cosmology seems very easy to analogise from the perspective of natural theology and many other forms of philosophical cosmology.

is physics incompatible with physicalism? well, I suppose that depends on if the laws of physics, which have no spatial extension in themselves, precede the existence of physically extended entities, or come into being after those physically extended entities are limited and therefore defined. fools often say that the laws of physics are simply “descriptions” the physical world, and do not exist apart from our conception of them. but they fail to answer the question as to how the world that we perceive is limited in such a way as to allow the abstraction of unchanging laws from it.

if not by the laws of physics in combination with some teleological force, how are things limited and compartmentalized in their limitation as they are?

I don't think that the difference is a matter of "location in space". The pattern on the shirt can be seen and can be measured as occupying space, the one in the designer's mind cannot. The spatial existence of the two is what is different. If being able to be measured, and having spatial relations with other things is having a "location in space", then the imaginary pattern has no location in space. That, I think is the principal difference, the pattern on the shirt can be said to have a spatial location, but the imaginary one cannot.

This huge difference is why we're better off to move to something like what you mentioned, "instructions", or what I mentioned, a "plan" or 'blueprints", to understand the creation of the pattern on the shirt. We can say that the instructions have physical existence, on the paper, but this is a bunch of symbols which represent the ideas of what someone is supposed to do in order to create a shirt with a specified pattern. These ideas of what someone needs to do to create a specified physical object, are in minds.

There is no point in you and I discussing exactly where the pattern is, until we determine what a pattern is, because I think the pattern is what is specified about the shirt, and therefore is ideal, having no spatial location, and you think the pattern is what exists in the shirt therefore having a spatial location in the shirt. Studies in physics demonstrate that it is difficult, if not impossible, to assign spatial locations to parts (particles) within objects. So I think that my position is much more realistic than yours. The pattern is what is specified about the shirt, it is not something within the shirt. Can you agree with this, or would you prefer to demonstrate how you think that it is more realistic to conceive of the pattern as something in the shirt, or on the shirt, rather than something which is said about the shirt?

It seems to me that a judgment is a property of a decision, goal, or intent. What is ripe for you isn't overripe for your son. It is still in a state of ripeness that either you or your son prefer. It isn't that it is over ripe for your son, it is the same ripeness as it is for you, it's just that he prefer's his under ripe, whereas you prefer yours ripe. You aren't determining the ripeness of fruit. It is your judgment, or preference, of the current state of ripeness. Your judgment has to be about something, and it is about the current state of the fruit. You are committing a category error in projecting "good" or "bad" onto the fruit, when the fruit is only ripe, over ripe, or under ripe, not good or bad. Good and bad are properties of judgments.

Let's either use science we know and understand (which would exclude all the 'spooky stuff' from quantum physics which has yet to be understood), or let's allow for uncertainty and progress in scientific understanding (which would not rule out a direct mind-brain correlation just because we have yet to fully explain it).

It means that the thing has been judged to have that property.

That's nonsense. If it isn't a judgement which determines whether the fruit is ripe or not then how is the ripeness determined? Do you not see that there needs to be criteria as to what constitutes "ripe" and, that there needs to be a comparison of the fruit in relation to this criteria, in order for the fruit to be determined as ripe or not? If this comparison is not a judgement, then what is it?

This is the case when any properties are attributed to anything, it is a matter of judgement.

If your naturalism wants a reductionism of substance that corresponds to principles of understanding physicalism is incompatible namely because the principles will eventually become mathematical abstraction and mathematics.

I think physicalism or material reductionism is best considered an educational tool, organization/contextualization... It is infintely important to have an educated public that knows for instance the cell, DNA and genes are basic units and concepts that relate to biology and know what the are.
In terms of the grand philosophy I think as we move forward we will be looking at more computational/information based theories because it actually reflects our understanding and practice. In particular synthetic biology is much more focused and defined as a methodological approach to biology understanding and utilizing it as a technology than it is any overarching concerns like the origin or meaning of life...

Energy is not a physical object, it is an attribute, a property of moving objects, the capacity to do work. It is "physical" only in the sense that it is something attributed to an object. Energy is a property of an object. The problem here is that some people assign "existence" to properties without having any physical object to assign these attributes to and then they create the illusion that the attribute has existence all on its own. In this case someone would say that energy exists as something physical, independent of any object. But of course that's nonsensical to say that there is a property existing independently of all objects, unless we look at that property as a concept, then it is an abstraction, in the mind.

I'm starting to see a pattern now in your thinking. It appears like you want to say that the non-physical is real, so long as it is not consider to exist as physical objects. The imaginary pattern is real, but not an existing physical object, energy is real but not an existing physical object. For you, these things are real, and they are not physical objects. However, instead of recognizing that "not physical objects" means that they are "non-physical" you want to make the incoherent move of disassociating "physical" from "object", to say that these things are physical but not objects. Do you understand that "physical" is defined as "of the body"? This is why your move to disassociate "physical" from "object", allowing that things like energy, and imaginary patterns, are physical but not objects is incoherent, because it renders the term "physical" as incoherent and self-contradictory. There are things of the body (physical) without a body (object)

Physics is derived from the Greek 'study of nature', conventionally distinguished from metaphysics. So I would say, different in kind. Post Galilean science concentrates on what is quantifiable, first and foremost. The primary or measurable qualities or attributes of any subject are just those factors which can be precisely described in such terms. So the natural sciences likewise are conceived in mainly quantitative terms which is why physics is the paradigmatic science of modernity. But as the OP points out, in fact the ontological status equations, algorithms, and mathematical theorems, are themselves not something which can be located in the physical domain. So, yes, agree with you that metaphysics is in some fundamental way thinking about the nature of knowledge itself, about what it means to know.

Quick question to the thread some time a go I watched something on TED (link below) where someone with a phantom limb had an augmentation that preserved the nerve of the severed limb. When they added the prosthesis that essentially mimics what would be a natural foot he could stand up almost immediately.

So my question is does the immaterial phantom limbs count as evidence for conscious illusion for physicalism? or did the old phantom limb is an illusion count as evidence for physicalism?

Because I could run this case used to argue the irreducibility argument of consciousness too... I am unsure if it has already been used to do so as the only thing I need to prove in my mind the reducibility of consciousness to being based in a physical phenomenon is how lobotomy, dementia, brain injury and dementia clearly makes you significantly less or detectably non-conscious.

You seem to have agreed that we can talk about patterns without any judgement about whether or not these patterns exist.


Yes. We can talk about unicorns without establishing whether they exist too.

Quoting Metaphysician Undercover
So why do you want to make assertions about where they physically are?


I don't. I suppose I would be asserting where the origin of the pattern I'm talking about (which, as above, does not 'exist') physically is. Like a painting of a unicorn. I might say "the unicorn in that painting has black fur, that's unusual for a unicorn, and it looks like it's angry about something". Of course, the unicorn in question does not exist, neither do any of the unicorns I'm comparing it to in establishing it uniqueness, but that doesn't mean it's not relevant where the origin of my abstraction is located. Its about a presumption of shared experience. I see a shirt reflecting partly black, partly white light. I abstract from those light signals a pattern, as set of instructions (black....move an inch...white). I point out the origin of that abstraction, and even talk colloquially about its "being on the shirt" because I presume your mind is sufficiently like mine that you will form a similar abstraction.

But you might not. And that's the important point. There's no rule forcing you to abstract the same idea from the shirt as I do, so there's no generalised idea that exists independently of those two ideas in our minds. It's simply a convenience, given the likelihood that our two abstractions will be very similar, to talk about them as if they were one thing.

As so often happens in philosophy, what we can successfully talk about has been confused with what we can actually demonstrate to be ontologically the case.

Reply to Dusty of Sky If you didn’t understand that the mathematics derives from measuring physical phenomenon then you’d likely make the faulty assumption you have in the OP.

So, the laws of physics are observed and measured (meaning not measuring some imaginary event!) and mathematical abstractions are then created - thought up - in order to make useful and applicable predictions about how experienced phenomena relate - or don’t relate!

From this the world of Pure Mathematics has branched off into its own little field of play and on occasions what we deem as “physics” meets up with “pure maths”. Really they are both extension of the same principle - that is to measure, by some given arbitrary units, events and to put these read measurements to use in order to theorise what has, will and is happening.

If abstract concepts cannot be related to physical phenomenon then they are useless to physics. Once they are discovered to relate to physical phenomenon then they are obviously no longer ‘useless’.

Where’s the confusion?

I've never abstracted instructions from a shirt, unless there was something written on the shirt. I don't see much point in continuing this discussion.

We make judgements about anything. Do you recognize the difference between the thing and what is attributed to the thing (a property)? Or, the difference between the subject and the predicate? To say that something has a specific property does not mean that the thing actually has that property, the statement is a reflection of a judgement. It means that the thing has been judged to have that property.

I already explained how saying something has a specific property does not mean that the thing has that property. Like I said, "The apple is red" is making a category error in attributing redness to the apple when it is actually a property of the apple, light and your sensory system. Like I said, redness carries information about all three causes, not just the apple. Just as a doctor can test your sensory system by making you look at letters, the letters are the constant, but our sensory systems could be different and create different visual effects in our minds. We can make different judgments about the letters, but the letters don't change. In other words, the letters have properties in and of themselves that makes them letters regardless of our individual judgments. If they didn't, then how could the doctor test your vision?


Quoting Metaphysician Undercover
That's nonsense. If it isn't a judgement which determines whether the fruit is ripe or not then how is the ripeness determined? Do you not see that there needs to be criteria as to what constitutes "ripe" and, that there needs to be a comparison of the fruit in relation to this criteria, in order for the fruit to be determined as ripe or not? If this comparison is not a judgement, then what is it?

This is the case when any properties are attributed to anything, it is a matter of judgement.

I think you are confusing categorizations with judgments. Sure, humans create arbitrary categories to make sense of the world. These categories can vary from person to person and what one considers "ripe", another might consider "over ripe", but we are still both talking about the same thing - some property of the apple that we refer to as ripe. If we both weren't talking about the same apple, then we would both be talking past each other. If I was referring to the apple when using the word, "ripe", and you were referring to your judgment, then we would both be talking past each other. When I say that the apple is ripe, am I talking about the apple in your head, my head, or there on the table?

Is thinking a property of you? Are you a thinking entity? Is your thinking a judgment of mine, or is it really a property of you - part of what it means to be you?

Physicalism is the idea that nothing exists except for concrete objects in the material world. But physics is the study of the mathematic principles which determine the behavior of these material objects. And these abstract principles (e.g. F=G(m1m2)/r^2) surely don't exist in the material world. You can't locate them under a microscope. So acknowledging that the laws of physics exist seems to contradict the theory of physicalism. Thoughts?


It's much bigger than physics, I think.

Quoting Dusty of Sky
Physicalism is the idea that nothing exists except for concrete objects in the material world.


OK.

But science - the discipline(s) of science, not its subject matter - is not a concrete object in the material world. It's a concept, an immaterial thing. So it doesn't exist. The same applies to philosophy, for example. And religion. Oh, and politics. ... Capitalism. Greed. The American Way. Beauty. Happiness. Ambition. Joy. The list goes on and on...

Your arguments stand, I think. I can see no justification at all for this physicalism. It is wrong because it is incomplete. There are things that exist which it denies, or cannot see.

Quoting Wayfarer
Physics is derived from the Greek 'study of nature', conventionally distinguished from metaphysics. So I would say, different in kind. Post Galilean science concentrates on what is quantifiable, first and foremost. The primary or measurable qualities or attributes of any subject are just those factors which can be precisely described in such terms. So the natural sciences likewise are conceived in mainly quantitative terms which is why physics is the paradigmatic science of modernity. But as the OP points out, in fact the ontological status equations, algorithms, and mathematical theorems, are themselves not something which can be located in the physical domain. So, yes, agree with you that metaphysics is in some fundamental way thinking about the nature of knowledge itself, about what it means to know. That is mostly shoved aside or ignored or taken for granted in a lot of analytical philosophy.


OK. So as I see it, metaphysics is 'the study of the study of nature'. My observation here is that investigation begins with qualitative interactions with nature. That is, something can't be measured unless it can first be experienced, observed or otherwise interacted with. So those interactions become the material to be formalized. But that investigative process assumes observers, goals, tools and schemas.

However those observers, goals, tools and schemas are themselves part of the natural world that, in turn, can be investigated and therefore become material that can be formalized. So the qualitative and quantitative are present in both investigative processes, the second process being meta in the sense that it is reflective and self-aware.

Categorization is clearly a form of judgement.

These categories can vary from person to person and what one considers "ripe", another might consider "over ripe", but we are still both talking about the same thing - some property of the apple that we refer to as ripe. If we both weren't talking about the same apple, then we would both be talking past each other.


That the two different people are talking about the same thing needs to be established, that's why we have the law of identity. We identify the thing, in this case it is what we call "the apple", and we agree that this particular thing will be called "the apple". But how do we identify a property? I suggest that we do this with a definition, and this is why I say that we need to refer to some criteria (the definition), to judge whether the thing (called the apple) is ripe or not. If we do not agree on the definition of "ripe", which is often the case, then we are talking past each other.

Quoting Harry Hindu
When I say that the apple is ripe, am I talking about the apple in your head, my head, or there on the table?


You are talking about the thing, which you have identified as "the apple". So "the apple" is the subject of discussion, and this subject is related to that object by means of identity. That it is "ripe", what you predicate of that subject, is your judgement, and this is in your mind, just like the subject, the apple, is also in your mind. So in your mind you have judged "the apple is ripe", an act of predication, and this relates to the thing you have identified, because that thing is what you call 'the apple".

Is this just another judgment, or are you actually explaining what is the case - that the doctor is making a judgment? You end up with an infinite regress of judgments which just becomes incoherent. Is the universe one big judgment? Does that even make sense?

You have to realize that judgments are about things, and it is what those judgments are about that matter. Sure, it could be that judgments is all you can do and make of the world, but the aboutness of those judgments creates a relationship that we usually refer to as "accuracy", so judgments themselves have a property of accuracy where they are more or less representative of what they are about.

Instead of "judgment", I think I prefer "interpretation". Our senses don't lie, but we can lie to ourselves by interpreting sensory data incorrectly. In interpreting sensory data, we are attempting to determine what they are about. What they're cause is. If they have no cause, then solipsism would be the case, which is what it seems that you are ultimately arguing for.

If they have a cause, then realism is the case and our sensory data actually has meaning in that they are the effect of prior causes - like your body interacting with the world that other minds share.

How else can you explain similar judgments by similar minds? Think about it. If we are all separate minds without a shared world (if that makes any sense) then how is it that we came to similar judgments about our separate sensory data - like that there is an "external" world and that there are other minds, and that you are similar enough to be part of a group of similar entities called "human beings"? How is it that "norms" can even be established and referred to? How is it that language could evolve at all?

I see no need to bring in an infinite regress here. Of course a regress is possible though. If someone makes a judgement, and another asks for the reasoning, or justification for that judgement, then the judgement which follows in explanation, and so on, there would be regress. The regress would not be infinite though, because we are finite beings with finite capacities, so the regress would be limited to the point where someone would break it off and the issue would be left unresolved.

"Interpretation" implies explanation, and very often we judge things without explaining them, so judgement is a far better term here.

Similar minds seeing things in similar ways is explained by "similar minds". I'm not denying that there is a "shared world", what I am denying is that what we (as similar minds) say of the world, is the way that the world is. Remember, I am not questioning the thing, I am questioning the properties. For instance, that the red of the apple is "a property of the apple, light and your sensory system". That is just what you say of the world, it is not necessarily reality.

As long as an individual is judged as within the norm, then that person is correct. But correct, as the norm, does not mean that this is the way the world is. For example, we see that the sun rises and sets, and we might conclude that the sun circles the earth. This might become the norm, the sun circles the earth, and this idea could be judged as correct and be the norm. Just because it is the norm, and correct, does not mean that it is the way that things are.

This does not follow logically, because both "point" and "extension" require a definition, they are mathematical terms, like numbers, things which are not sensed, but understood by definition. If we agree that what I am sensing is called a "tape measure", there is no point to asking whether that tape measure is a point, an extension, or both, without defining the terms.

As I implied in the last post though, to talk about a particular extension requires the assumption of non-physical points, to separate that particular part from the rest of the tape measure.

But if you're just gonna be a complete skeptic, then I can't think of any rational argument to convince you to change your mind. It seems like you're saying "maybe the universe is fundamentally inconceivable, so therefore there's no point in trying to use reason to understand it." If you're right, then I can't use reason to prove you wrong. Maybe reason is just a useful tool for building rocket-ships and laptops. I can't imagine how reason could be so useful without being capable of deducing authentic truths about reality. But maybe the only reason I can't imagine that is that I'm relying on my faulty powers of reasoning. So all I can think to do at this point is make an emotional appeal. Don't you want to understand the world you live in? The only reason that reason is such a useful tool is that we presume that it communicates truth about the way things really are. If we just treat it like an arbitrary construct of human subjectivity, then I suspect it will behave like one. Newton and Einstein didn't make their great discoveries because they thought they were merely using a tool. They believed themselves to be uncovering the secrets of existence.

But perhaps I'm misinterpreting you, and you're no really a skeptic and or pragmatist.

Assuming an external law wouldn't move us closer to an explanation. It would just raise the question of why there happens to be one particular law in effect rather than another.


I agree. And unless you think that there's an infinite regress of laws, you have to eventually ask why law A is in effect rather than law B or C. And regardless of what your answer is, I don't think you can attribute it to physical objects or their features. Laws are unchanging and exert control over all activity throughout the entire universe, whereas physical objects and their features change and they are limited to particular regions of space time.

This is the sort of thing it's worth doing philosophy over--"Thinking hard" about what it is that you sense.


I think maybe it's the passing of time that I sense. What do you think?

I attribute unchanging laws to the universe itself, one example being the law of non-contradiction. In its ontological sense, it's a form that is exhibited universally (i.e., in all objects).

I see no need to separate out form (laws/rules) from the universe. I think this comes down to a philosophical choice here - whether one prefers to conceptualize things in a unitary or dualist sense.

I think that we sense relations including extension. :wink:

Seriously, though, it depends on the kind of physicalism we are talking about. Regarding the OP ?Dusty of Sky I doubt many physicalists, or any sensible physicalist, would claim that nothing exists except "concrete objects in a material world" since elementary particles are not, according to current physical theory, any such thing; they are fields or waves or intensities in a field. On that conception of the physical, why could ideas, equations or theories not also be such?


They ought to, then, give up the term physicalism with its baggage. What gets called physical has been extended to include thigns that would not have been considered physical earlier in history - by materialists,say. Anything that is considered real, will be called physical, so the term has no meaning. It gets even worse if one considers equations real, because there is no way to observe them and there is not even a hypothesis about what they are made of. They are transcendent.

Is physicalism incompatible with morality?

Reply to Delilah Perez No.

Also no to the OP.

Reply to Pfhorrest could you explain why it’s a homework question and I am having trouble with it. I need to explain 3 reasons yes and 3 reasons no.

Reply to Delilah Perez 2 entries from me:

Physicalism is incompatible with morality because if a human being is just a set of atoms like any other, why consider her life inherently more valuable than her death? If humans are just machines, they should be disposable like machines are, once the cost of their maintenance exceeds their utility.

Physicalism is compatible with morality because morality is but the codification of our species social, collaborative instincts, which were shaped by Darwinian evolution, itself compatible with physicalism.

Reply to Olivier5 Ok thanks could you please give me some examples of why the answer should be no.
Olivier5 October 16, 2020 at 22:08 #461834
Reply to Delilah Perez I did give one.
Delilah Perez October 16, 2020 at 22:12 #461837
Reply to Olivier5 oh no I’m sorry I meant could you give me examples on why the answer is yes. Lol sorry I’m being annoying I just don’t really understand the question .
