The modal argument for dualism
Here's what I understand about this argument. Versions of it has been used by Kripke and Chalmers and here by Plantinga to argue that we are not our bodies or brains. The argument goes like this: Imagine yourself without a body. That seems easy enough. Can you imagine your body without its body? It seems not. That would be patently contradictory. Thus, your mind must have at least one property that your body doesn't: namely the modal property of possibly existing without a body. By Leibniz's law, they cannot be identical. That law simply says that everything has the property it has. If A has a property B does not have, they are not identical by that law. Your mind would have the modal property of possibly existing without a body while your body cannot exist without itself.
There are at least two ways to attack this. One may wish to deny Leibniz's law for modal properties; that is, one may wish to assert that it is possible for some things to have some modal properties they don't have. But I don't see this as a plausible avenue. It seems to me that Leibniz's law is true unrestricted, true for all properties, genuine, relational and modal.
So I will concentrate on the other possible objection which I will term the epistemic constraint to modality (ECM). It may seem plausible at first that anything one can imagine being true may be true in some possible world. Your car may be green when it is actually red. We know that your car has the modal property of possibly being green. How do we know that? We just imagine it so and if we can imagine it so, it is possible it is so. That's how we seem to know what is and isn't possible in the broadest sense. I can imagine your car being green when it's red and thus it must have the modal property of possibly green. I cannot imagine your car being green all over and red all over at the same time and thus your car must not have the modal property of being possibly green and red all over at the same time.
But does this kind of epistemic access always cut modality at its joints? Cut it precisely such that the space of epistemic possibility covers the same space as the modal space? Let's imagine we live 500 years ago. We would know what water was. It's that clear, potable, odorless liquid. Can we imagine it not being H2O? Yep, I believe we can. We could imagine it being XYZ for example. But we now know that water = H2O. It could not have been possible that water did not turn out to be H2O because water = H2O is a necessary identity statement. This is a case where our epistemic space over steps the boundaries of possibility. Thus zombies may not be possible though we can (now) imagine them.
Defenders of the claim that epistemic space and modal space are perfectly overlapping can deny that people 500 years ago really can imagine that water = H2O because they are not thinking about water when they imagine it not being H2O. But this doesn't seem like a way to defend that claim because then how would we know we are talking about or believing anything about some putative object when we imagine it being so (having some property) when science may tell us one day that it does not have that property? It doesn't seem that my ability to refer and to think about things are so dependent on contingencies in future scientific discovery.

Copy and original revisited
Object A is a copy iff its creation was intended as a copy of some object B (or maybe even an idea of such an object) and A does not (numerically) equal B.
Puzzle of the self-torturer revisted
Dimensions
In 1968 Melzack and Kenneth Casey described pain in terms of its three dimensions: "Sensory-discriminative" (sense of the intensity, location, quality and duration of the pain), "Affective-motivational" (unpleasantness and urge to escape the unpleasantness), and "Cognitive-evaluative" (cognitions such as appraisal, cultural values, distraction and hypnotic suggestion).[40] They theorized that pain intensity (the sensory discriminative dimension) and unpleasantness (the affective-motivational dimension) are not simply determined by the magnitude of the painful stimulus, but “higher” cognitive activities (the cognitive-evaluative dimension) can influence perceived intensity and unpleasantness. Cognitive activities "may affect both sensory and affective experience or they may modify primarily the affective-motivational dimension. Thus, excitement in games or war appears to block both dimensions of pain, while suggestion and placebos may modulate the affective-motivational dimension and leave the sensory-discriminative dimension relatively undisturbed." (p. 432) The paper ends with a call to action: "Pain can be treated not only by trying to cut down the sensory input by anesthetic block, surgical intervention and the like, but also by influencing the motivational-affective and cognitive factors as well." (p. 435)
The old children's story of the frog in the pot who is slowly being boiled alive reminds me of this self torturer puzzle. The frog may suddenly feel a sharp rise in pain once some threshold (psychological or otherwise) is reached and jump right out instead of being boiled alive. That would seem realistic and explanatory and thus dissolve the puzzle of the self torturer as well.
In 2002 Dr. Victor H. Hutchison, Professor Emeritus of Zoology at the University of Oklahoma, with a research interest in thermal relations of amphibians, said that "The legend is entirely incorrect!". He described how the critical thermal maximum for many frog species has been determined by contemporary research experiments: as the water is heated by about 2 °F, or 1.1 °C, per minute, the frog becomes increasingly active as it tries to escape, and eventually jumps out if the container allows it.[3][21]

Puzzle of the self-torturer?
Suppose someone — who, for reasons that will become apparent, Quinn calls the self-torturer — has a special electric device attached to him. The device has 1001 settings: 0, 1, 2, 3, …, 1000 and works as follows: moving up a setting raises, by a tiny increment, the amount of electric current applied to the self-torturer's body. The increments in current are so small that the self-torturer cannot tell the difference between adjacent settings. He can, however, tell the difference between settings that are far apart. And, in fact, there are settings at which the self-torturer would experience excruciating pain. Once a week, the self-torturer can compare all the different settings. He must then go back to the setting he was at and decide if he wants to move up a setting. If he does so, he gets $10,000, but he can never permanently return to a lower setting. Like most of us, the self-torturer would like to increase his fortune but also cares about feeling well. Since the self-torturer cannot feel any difference in comfort between adjacent settings but gets $10,000 at each advance, he prefers, for any two consecutive settings s and s+1, stopping at s+1 to stopping at s. But, since he does not want to live in excruciating pain, even for a great fortune, he also prefers stopping at a low setting, such as 0, over stopping at a high setting, such as 1000
This passage as stated states that the increments to be increased are of the devices settings (i.e. amount of electric current). But the "puzzle" seem to arise when we consider increments of degrees of pain.

Poem
Love of Wisdom
Often homes are built
Over an abyss
The structural supports of lies and fallacy
The philosopher, never remiss
In demolishing false security
With a wrecking ball of analysis
Watch the house of cards as it falls
Upon sounder base shall be built
The Chamber of hallowed halls

More pessimistic ethics and political philosophy
Morality as we know it (useful fictions?)
What if most of the ethics or morality we know in philosophy or common sense ethical reasoning are seriously shaped by our building of fictions based on ethical intuitions? That's not to say that necessarily these intuitions are wrong (error theory on these intuitions). Even if they are right these intuitions may be based on one or a few paradigm cases and though have some truth in them, small inaccuracies in the way morality is built up from them may magnify and cause ever more fictions to be built on top of earlier formulations. These fictions may in turn cause frictions with either each other or other aspects of what we know. That's not to say that harmonization of these fictions with each other and other aspects of our knowledge are not possible, it's just to say that any harmonization may be in some sense arbitrary and based on fictions.
As one example could it be that our intuitions regarding moral responsibility and especially contempt and its opposite, praise of moral character, are based on fictions we have of each others characters such as that these character traits are relatively permanent (maybe even across possible worlds) and rather consistent with other character traits of the individual? We may have invented conceptions of personhood as enbodying relatively permanent and consistent character traits based on justifying our practices of attributing blame and contempt, eg such as fictions regarding people's character or personality. It may also be based on the fiction of alternative possibilities assuming that it is a fiction (my point is that we don't know if determinism is true and so my calling it an invented fiction may be justified on that epistemic lacuna). As we know more about the world, we would have to come to ever more elaborate fictions to justify our practices or else risk not being able to justify them as they conflict either with each other or with other notions. If determinism is true, we may have to change our conceptions of what it means to be a person (i.e., come up with further fictions which in turn may or may not come into conflict with either other moral intuitions or what we will learn in the future about the world).
Let's say that one day we were to learn that the Nazis are very much like us. That is, that had most Nazis been raised in different environments like ours or we had been raised in theirs, they would have turned out very differently and not been subject to the contempt we have of them and may even be the objects of praise. Consider Hitler; it's possible that had he been raised differently, he might have turned out a good person. We may have invented a character type for him which is false and his fellow Nazis. Since many of our reasoning may be based on using paradigm cases of evil and these are our paradigms, many of our reasoning may be contaminated in a sense.
This is analogous to the fictions we sometimes invent (as the story goes) in mathematics such as inventing the fiction of sets, etc. Now it may the true that some of our “fictions” may actually turn out true in which case they would not be fictions but it seems that they could as well turn out to be fictions and the long history of ad hoc rationalizing and creating of fictions needed to form coherent pictures of either morality or mathematics may count against them as such. If they turn out true, that would be coincidental.
However, there may be moral facts out there. It's just that they may not square well at all with our moral common sense or reasoning as these maybe the products of our fiction building as well as our intuitions. Moral facts and a truthful moral theory may be far more nuanced and unrecognizable from all of our notions.
