    My Modern Philosophy Professor was teaching us that the medievals attempted to make a metaphysic around substance through aristotle's 4 causes. However the problem was that they could not account for "interaction" between substances. The moderns would then recreate metaphysics around this problem with the rationalists creating a bizarre version of the world and the empiricists who were skeptical about finding an explanations between causal "interaction". Could someone explain if the picture is accurate and explain what this problem of interaction is more thoroughly?

    @Metaphysician Undercover Should appear soon to answer. And small point: metaphysics: one metaphysics, many metaphysics. "Metaphysic" a solecism. Plural because then one subject took up multiple scrolls instead of fitting as a modern subject in a single book. E.g., politics, ethics, economics, physics, analytics. Singular nouns though seeming plural.

    It's the mind/body problem. And also the level of movement problem. The second entails the fact that no amount of microphysics can explain biological movement, and no amount of chemistry can explain phsychological movement. ETC. They are all real, measured, measurable, predictable, scientific, yet there is no interactive predicative or explanatory features between levels of movement.

    The mind/body problem is so simple to understand that I shan't insult anyone's intelligence by explaining it. Basically it says that the mind is real, the body is real, the mind is connected to the body, but how and where?

    Ever since Plato introduced the "tripartite soul", there hasn't really been an interaction problem, because the principles are there to resolve it, for anyone who wants to. "Spirit" is the third feature which accounts for the interaction between body and mind.

    The interaction problem is commonly presented by monists who reject the eternal Forms of Platonism. It is argued that eternal forms could not interact with temporal bodies. But as Aristotle showed, so long as the two distinct substances are represented as actual, therefore active, there is no problem with interaction between dual substances. The appearance of a problem is a result of representing one of the two substances as necessarily passive, by being eternal, outside of time. This indicates that the understand of time which is involved with the concept of "eternal forms" is faulty. So the "interaction problem" is the manifestation of a misunderstanding of time.

    The reason why it is argued that eternal Forms cannot interact is that they are eternal, therefore outside of time, unchanging and necessarily inactive, as activity requires time. If we allow that immaterial Forms are active, they are only outside of time if time is conceived of as being a property of physical change.

    Introducing another substance just adds fuel to the fire.

    The interaction between "substances" is a problem for naive realists who believe that the world is as they see it, rather than symbolizing how the world is. It's as if they think that the symbols (the brain) are distinct from the symbolizing (the mind).

    What this is basically saying is that two substances are more similar than dissimilar, something that leans more towards monism. The point being is that you have to represent the substances as being more similar in order to explain how they interact.

    So instead of introducing the supernatural (the eternal) to account for the natural. It's all natural, including gods and where they live, if they were to exist.

    That's not what I meant. All you are saying, is that by naming them both as "substance", they are therefore more similar than dissimilar. But that does not follow logically at all. Placing two things in the same category doesn't mean that they are necessarily more similar than dissimilar. All I did was find some principle of similarity, such that the two could be placed in the same category. In no way does this indicate that they are more similar than dissimilar. "Substance dualism" does not imply that the two proposed substances are more similar than dissimilar because they are both called substance.

    If we deny absolute passivity as impossible, unreal, because it is not in any possible way actual, then it is excluded from our discussion, and our two opposing extremes are both forms of activity, they are actual. One could be extremely fast and the other extremely slow for example, but they are opposing extremes, and it makes no sense to say that they are more similar than dissimilar. Now, if we want to validate these two as acceptable extremes we need to substantiate them. Since they are opposing extremes each will be substantiated by a different demonstration, hence distinct substances.

    So instead of introducing the supernatural (the eternal) to account for the natural. It's all natural, including gods and where they live, if they were to exist.Harry Hindu

    I think it's a fool who equates the supernatural with the eternal. We do not need to apprehend "eternal" to apprehend "supernatural". What I've been trying to say, is that the dichotomy which pits the eternal as opposed to the temporal, resulting in the interaction problem, is not a fair representation of classical dualism. It's a strawman.

    The interaction problem is that if there are two substances that interact, they must have something in common by virtue of which they can interact. But if they have something in common, that common thing is more fundamental than the substances, so the substances are not really substances after all. Conclusion: there cannot be a plurality of substances that interact. There could, perhaps, be a plurality of substances that cannot interact ever, even in principle. But as they can never have any bearing on our universe whatever, it's not worth even thinking about them.

    I can't see your point Harry. If we have liquid water and solid ice, and someone argues that ice is never liquid, and liquid is never ice, therefore the two can never interact, we must explain freezing and thawing in order to understand the interaction.

We can represent two things as distinct, hydrogen and oxygen for example, but the fact that they are described as distinct does not create a problem of interaction. There is only a problem of interaction if the two distinct things are represented as incapable of interacting with each other. This is the strawman type of representation which monists project onto substance dualism, to create the illusion of an interaction problem. But of course it's just a strawman because substance dualists do not represent the two substances as incapable of interacting with each other, as I've explained. They represent them as interacting. The fact that explaining the interaction requires adding more to the mix is just a feature of the complexities of reality.

    This is just dumb. We don't use thawing as an explanation to explain the interaction between ice and liquid. Why do we need "thawing" to explain how a glass of liquid behaves when ice cubes are dropped inside it. Thawing doesn't explain how the liquid gets displaced then the glass overflows. Physics is what explains that.

    I have a better example that we can use. How does software interact with hardware? Do we need to assert the existence of spirits to account for how software and hardware interact in your computer?

    The "point" is that these questions remain unanswered, and they need to be answered in order for us to have an adequate understanding of reality, like wave/particle duality in physics for example.

    No, what is measured, in the case of measuring the heat, does not determine the state of the object. As I explained, further deductive logic is required. You point the thermometer at the object and it gives you the temperature. It does not tell you whether it is frozen or liquid.

    The fact that you find them interesting has no bearing on whether or not they are ontologically fundamental.Harry Hindu

    What I meant is that they are interesting to me because they are ontologically fundamental. if you want to dispute that, as not evident to you, then that is your prerogative. But so far you are quibbling over nonsensical strawman representations, refusing to go anywhere near that subject.

    In fact, your interest implies that they are epistemological in nature rather than ontological. You need to define "substance" to explain why only two things qualify as a substance and not all the other things that interact.Harry Hindu

    Actually, it is you who is trying to turn this from an ontological issue into an epistemological issue, by insisting on a definition. In metaphysics we take the term, and attempt to determine what it refers to, through the usage presented, to determine the actual reality, or unreality (in the case of misunderstanding) of that thing referred to. To start with a definition would only prejudice the inquiry, misleading us, as Plato demonstrated in the case of "knowledge" in his "Theaetetus".

    So, in this case, we are starting with the assumption that there are two fundamental substances, and we are inquiring whether there is an interaction problem between them. My argument is that the supposed interaction problem is only the result of defining "substance" in a prejudicial way, which creates the illusion of an interaction problem. If we adhere to normal usage of "substance" there is no such interaction problem.

    Your objection appears to be why is there supposed to be two fundamental substances rather than a different number. This is the result of previous metaphysics, which sees the need for a distinction between material substance and immaterial. And as I explained, it is supported by modern physics with wave (immaterial), particle (material) duality. Clearly, the physics of waves is distinct from the physics of particles, as the substance of each is different, yet there is some form of interaction.

And, I infer that there is immaterial substance in your mind. But there is something which separates our minds, a medium between us, which is evidently material substance. You might wish to call it something else, but I think it's acceptable and customary to refer to this medium which separates our minds as material substance. Do you not agree that it is also acceptable and customary to refer to the ideas and concepts within your mind and my mind as immaterial substance? If not, I think that you are attempting to force a definition of "substance" which is unacceptable. What are your epistemic standards for "substance" then?

    Doesn't the fact that the words of some "long-dead human" still exist, and are still respected by many as authoritative mean anything to you? I suppose that you could just reject the idea that there is any importance to those words, and assume that this is all a random coincidence, that the words still exist and are accepted by many as authoritative. But since the words of billions of other human beings who have lived in the time period between then and now, are not respected as authoritative, and are therefore not still existing, I think it is only a fool who would make such an assumption.

    And a mighty fine assumption, too. But in the end just an assumption. And it highlights not one but at least two problems. First the connection between mind and body - on the assumption they're different. And a problem that lurks in the background, the connection between conjecture and the world.

    That is, anyone can make models based on assumptions, and for their respective purposes some of those models work pretty well and are productive. Question: when do the models become real?

    As you said, it's a "mighty fine assumption", and that's because it's based in true experience. That's what distinguishes it from many other metaphysical assumptions which tend to be purely speculative conjectures based in some fantasy.

    Of course, everyone knows that a model is a model, and that it's reality is as a model. I think that's sort of obvious. And this is fundamental to substance dualism. What substantiates the model as something real, it's dependence on a mind, is completely different from what substantiates the reality of the thing being modeled, as not necessarily dependent on a mind. Hence substance dualism.

    You are making an unwarranted assertion that the medium between minds is different than the medium of your mind - hence you create the problem of dualism that you are attempting to fix, and the way you are fixing it is to assert that the mediums are not so different after all, which is more like what monism is saying. So you keep going back and forth between the mediums being distinct, yet similar. Which is it, and how much do the mediums need to share before you agree that they are the same type of substance?

    Have you studied any physics. Science holds that waves are patterns of motion within a material substance composed of parts. They are a change in the relations between the parts of the material substance. As such, the substance is material and the wave is immaterial.

    The wave-particle duality is an epistemological distinction, not an ontological one.Harry Hindu

    What are you talking about Harry? Wave-particle duality is a description supposed to be concerning the reality of what is, therefore it is ontological. It refers to two distinct aspects of the same situation being described, the wavefunction, and the particle. It is not two distinct descriptions of the very same thing, therefore not an epistemological distinction. Failure to recognize that the "wavefunction" and "the particle" refer to two distinct things assuming that they both refer to the very same thing, would create many contradictions. Epistemology does not allow contradiction therefore we must maintain that the distinction is ontological.

    You are making an unwarranted assertion that the medium between minds is different than the medium of your mind...Harry Hindu

    It's clearly not unwarranted. Something must constitute the separation between minds. If what was between your mind and my mind was the same thing as what's in my mind, and the same as what's in your mind, there would be no separation between our minds. However, we experience separation. We cannot posit a real boundary between one thing and another, unless there is a different sort of substance which constitutes the boundary. A boundary is only real (substantial) if there is a difference of substance. If it is all water, within my mind, and yours, and everywhere between us, then there is no separation between us. If it is evident that there is a separation, as it is, then we need to posit another substance which forms the boundary.

    Science holds that waves are patterns of motion within a material substance composed of parts. They are a change in the relations between the parts of the material substance. As such, the substance is material and the wave is immaterial.Metaphysician Undercover
    Which is the same as saying that pattern and the substance are one and the same as you can never have one without the other - ontologically. The distinction you are talking about only exists in your mind as language concepts.

    What are you talking about Harry? Wave-particle duality is a description supposed to be concerning the reality of what is, therefore it is ontological. It refers to two distinct aspects of the same situation being described, the wavefunction, and the particle. It is not two distinct descriptions of the very same thing, therefore not an epistemological distinction. Failure to recognize that the "wavefunction" and "the particle" refer to two distinct things assuming that they both refer to the very same thing, would create many contradictions. Epistemology does not allow contradiction therefore we must maintain that the distinction is ontological.Metaphysician Undercover
    It's missing the critical component of consciousness as an observer and how the mind is only a representation of what is happening, not a clear window to what is actually happening.

    I am now wondering if part of the problem is that dualists seem to think that they see the world as it is (naive realists), and how it appears is different than how it is thought about - hence dualism. You think that the duality exists ontologically, and are unwilling to ponder the possibility that the way it appears in the mind may be different than how it actually is (but that isn't necessarily saying that we can never know about how it actually is). What I'm basically arguing is that particle-wave duality is like a mirage or a bent straw in a glass of water with ice. - an illusion. Illusions, however, are ontological. Their interpretation is epistemological. Epistemology is about the ontology of knowledge. All dualisms resolve to a monism.

    It's clearly not unwarranted. Something must constitute the separation between minds. If what was between your mind and my mind was the same thing as what's in my mind, and the same as what's in your mind, there would be no separation between our minds. However, we experience separation. We cannot posit a real boundary between one thing and another, unless there is a different sort of substance which constitutes the boundary. A boundary is only real (substantial) if there is a difference of substance. If it is all water, within my mind, and yours, and everywhere between us, then there is no separation between us. If it is evident that there is a separation, as it is, then we need to posit another substance which forms the boundary.Metaphysician Undercover
    Pay attention to the bolded part: This can be said about earth, water, fire and air, so why dualism? Your focus on mind and body being special and fundamental would simply be a personal fetish with the two.

    You're assuming that there can't be different kinds of one "substance" (again, you haven't even explained what you mean by the word, or what qualifies as a "substance", so until you do, I'm assuming that you don't know what you're actually talking about when you use that word). Just as we have all the different elements that are just different configurations of atoms, we can have different configurations of one "substance". There are different configurations of the same "substance" between the configurations that are our minds.
