Not a problem. I still think that defining a term so that it only applies in a certain circumstance is special pleading though.
I don't think so. I've never had a common conception that a magic penny would have some sort of intelligent agent living inside it.
Well, it certainly succeeded in distracting from the discussion for a while if that was your intent. However, it didn't succeed in furthering your argument.
Organization? Please define that. Or more likely, redefine it to make it very specific so that the definition only applies to dualism lest I attempt to use it to describe something else.
It only violates the law of conservation of energy in the case of the mind/body problem and only then if you assume that the body is a closed system.
Please elaborate. What huge unexplainable gap does it leave?
It could be property dualism, neutral monism, or something else. I've never seen a reference that says that knowledge of how the supernatural interacts with the natural is impossible. Can you cite one please?
Leaving out that part of the description would not be special pleading. Putting it in is special pleading. You seem to be making an exception for one specific case without any justification other than you think that somehow calling something "magic" will make it seem irrational and you don't want things that you want to seem rational to also be called "magic." Why not just redefine the word "rational" to exclude belief in a god and be done with it?
OK, so here you've given one possible criteria for determining whether something is irrational: it lacks a causal account (by which I assume you to mean that the cause cannot be known).
Unfortunately, we've already established a lack of a causal account for other things such as quantum randomness, which I assume you feel are rational. At the same time, you haven't really given a valid reason why you feel that it is impossible for knowledge about the interaction between the supernatural and the natural to be known.
So now you seem to be qualifying your statement about a causal account -- that it only applies to organized (presumably meaning non-random) occurrences. You haven't really given a valid reason why it only applies to organized occurrences other than to eliminate quantum randomness from the "irrational" bin, which would amount to special pleading.
But of course gravity can't be explained and isn't random, so is that irrational?
That justification would apply to both organized and unorganized occurrences.
You already said that interaction between the supernatural and the natural is possible, which means that if it occurred, we could indeed observe it. Also, the coherence of the concept has already been established (that's what we mean by "it's possible."
Or neutral monism, or maybe something else. I'm just not convinced that the differences between materialism, neutral monism, property dualism, or something else support your assertion that belief that a personal god could interact with the natural world is irrational.
Maybe. Or maybe we don't currently have good ways to investigate their truth. But the same can be said of other things that you consider rational.
We've already agreed that both concepts are logically possible, so what do you mean by "physically possible" and why would that make the burden of evidence lower? Are you saying that there is a lower burden of evidence for the belief that teapots orbit Jupiter because it is physically possible?
And even if the burden of evidence was lower, there's no compelling evidence for either one. If there's no compelling evidence for something, there's no compelling evidence for it regardless of the burden of evidence.
You do realize "that is probable" implies a probability greater than 50%, right? So what sort of "circumstantial evidence" is there to conclude that, say, aliens are probable?
I see your point, but I don't accept that something being "physically possible" lowers the bar as far as evidence goes. If there were strong evidence for something that isn't currently considered "physically possible" we'd have to change the laws of physics just as we'd be inclined to believe anything for which there is strong evidence. If there is weak evidence, physically possible or otherwise, then we have no reason to assume that it's true, but we might still very well have an opinion about it.
I disagree. It appears to be an evidence issue that you're trying to special-plead out of by suggesting a higher burden of evidence for dualism but giving no concrete reasons why (nor even providing compelling evidence that dualism is required for the supernatural to interact with the natural).

I prepared a long answer and my computer just ate it, so here's a quick list instead.
1. The definition of 'magic' is not special pleading. It is a definition, so by definition it cannot take the form of that logical error.
2. "Magic" meaning that something organized occurs in this world without a possible explanation is just the way that most people do use the term, so I am not supplying anything special here. A magic penny works by doing something organized -- like granting a wish, etc. It fits precisely the same pattern. If magic pennies caused random subatomic particles to arise, we wouldn't call it magic. It could be that quantum weirdness is magic by this definition, that there is some organized force behind the world responsible for it. But there is no way that we could know that. We distinguish between the random, stochastic occurrences at this level and 'magic' because the latter includes the idea of either organization or intentionality or both.
3. Mind-body dualism consists of two entities -- mind and body. We cannot see mind. We can only see its effects on body. So, the only way to distinguish between a material monist and dualist account of "mind" is to provide a causal account of how it works. By definition, dualism cannot provide a causal account, only material monism can; that is how we distinguish them. If dualism could provide a causal account, then it would not be dualism. This is a fundamental definition issue, not an issue of what we currently know and don't know.
4. Dualism that involves the spiritual has the same feature. If it interacted through a describable mechanism, then it would not be dualist (which, by definition cannot work through causal, describable mechanisms since that is material monism), it would be monism.
5. I never once said that a god interacting with the world is impossible. In fact, I said the opposite. What I said was that we could not provide a mechanism (causal account) for how a personal God worked in the world because that is what dualism means (and I used the word 'magic' to denote this interaction problem). If God is made of the same material as us, then there is no issue, but that is not dualism, that is monism. If God acts in the world we could use that as evidence for the existence of God, but we could not, by definition, understand the mechanism by which He did it because God is not material, so does not work by means of causal/material action. His action in the world would be magic, a miracle.
6. A personal God is defined by theists as immaterial, hence dualism, if we accept that there is a material world. If you want to argue with their definition, then I suggest you take it up with them. But I would support the contention because divinity is considered something "other". 'Fundamentally other' means more than one substance. If God is made of the same stuff as us, then there is no problem by definition. That's just monism.
7. Property dualism (and neutral monism) suffers from the issue of an unexplainable way for differing fundamental (not mechanistic, like differences between iron and cobalt, which does have an explanation) properties to show in one thing and not another. Once again, if a mechanism were explainable, then it wouldn't be property dualism; it would be different attributes of a single fundamental substance (like iron and cobalt differing because of their atomic number, etc.) in a straight monism.
8. Please stop confusing the not yet explained with the fundamentally unexplainable. If something can be explained then it follows the laws of physics and is physically possible and is material. You are stuck on the level of attributes, not the fundamental. This is about fundamental properties/substances not the attributes of those substances in differing quantities/combinations/etc.
9. This is not just an evidence issue. We are not discussing proofs here, but beliefs. We believe based on justifications. We use four major criteria for this -- logical possibility, physical possibility, coherence of ideas and how they fit together, and physical evidence. If something is logically possible but physically impossible we are inclined not to believe it even if there is evidence. Did you believe the photos that convinced Arthur Conan Doyle that faeries exist? But what if you saw an official NASA photo of a teapot orbiting Jupiter along with a story that someone thought it would be funny actually to put a teapot up there? I would consider that much better evidence to convince me to believe that a teapot was up there than a picture of a faerie whatever story went along with it. It will always take more evidence to convince me of faeries existence because they are, by definition, physically impossible (not an infinite amount of evidence, however, just more). Sure, it could be that we have the wrong definition of physically possible, but if that is the case, then faeries are physically possible, and we simply need to reorient our way of thinking. This doesn't change the fact that it is much more difficult for us to believe in the physically impossible than in the physically possible, given the same sort of evidence. If our picture of the world is wrong, then our picture of the world is wrong, and this predisposes us to errors.
10. By definition, God is not in the category of the physically possible or impossible, but he is logically possible. It is not rational to believe in something simply because it is logically possible. Certain definitions of God are coherent too, so that's on His side. So, we are stuck back with evidence. We need more evidence to think of God as existing than we do for something like life on extrasolar planets (just like we need more evidence to believe that faeries exist than to believe that there is a teapot circling Jupiter) because we can't discuss God as physically possible. I have logical arguments for a particular type of God, so there is plenty of evidence (or arguments) for some varieties of God. But we are discussing a personal God here, not a God that we can decide exists in monism. The Drake equation argument is a category error. God is not in the same category as intelligent life on other planets, so the analogy is not appropriate.
11. Why in the world would any theist object to the idea that belief in a personal God is irrational? I thought one of the pillars of religious belief was that it is based in faith and not on logical argument and evidence.
12. I have no clue what would lead you to believe that I think something random/stochastic is rational. The word does not apply to the random. Similarly, it is not special pleading to suggest that mechanism or causal account does not apply to things that are random. By definition, if something is random, there is no possible causal account. Let me remind you, we are not discussing the appearance of things here, but their fundamental nature; just because something appears random could simply mean that we don't have the knowledge to supply the causal account. I already mentioned previously that there is a distinction between the theory of quantum mechanics and the observation of (potentially, since we could arrive at a more fundamental account to explain quantum foam) quantum weirdness. There is no causal account for quantum weirdness within quantum mechanics. We have an uncertainty theorem, but that doesn't tell us why things are the way they are. Part of the reason that super smart people like Richard Feynman tell us that if we think we understand quantum mechanics then we don't is because of this issue.
13. Something unexplainable within materialism does not make materialism irrational. It means that there is something unexplainable. We don't know for sure that quantum weirdness is unexplainable, though. We know that we haven't got an explanation, but that differs from things that, by definition, we cannot provide an explanation.
