...continued Moving on: "That someone has been caused to think something doesn't mean he has a reason for thinking something." True enough, and nothing in my position either implies or is predicated on the assumption that they would. On the other hand, in cases like this, there is a reason that they had the thought, namely whatever it was that caused the thought. I bring this up because I am wondering whether there is some unwarranted conflation going on between these two different uses of 'reason'. If not, could you explain more fully the significance you see in this comment? Next: ”The materialist view of the mind closes off any other way in which likeness can be achieved, because (if it's consistent) it postulates that brain states, ultimately reducible to fundamental particles, are all that objectively exist." If, by likeness, you mean some correspondence between a thought about the world and the world as it is, then information flow along causal chains might do that, and you have not said anything which shows that it cannot. On the other hand, it is not necessary to show that this must happen, as chain-of-causality provides a plausible answer to the central question without requiring any particular likeness. Another problem with this statement is that, as it stands, the clause following the 'because' does not appear to explain or justify the clause preceding it. If you think it does, please explain. As I write this, I see there might be yet another problem over what 'any other way' in the conclusion is referring to - it appears to be 'a chain' from the preceding sentence, presumably a chain of causality. Did you intend your conclusion to be ' the materialist view of the mind closes off any way, other than a chain of causality, in which likeness can be achieved?' If it is, I do not discern what this is intended to refute. Regardless, this is a metaphysical claim. I prefer to avoid using such things, as they tend to take the form of intellectual overreach into areas where nothing definite can be said. We can approach the question of whether the mind is a physical phenomenon without metaphysics, just as we can do the same with the question of whether the weather is a physical phenomenon. ”You claim "an understanding of causality may potentially lead us to being able to say... in what way thoughts are similar to reality", but you offer no details...” Well, there has been no pressing need for me to do so, as chain-of-causality offers an answer to the central question without involving similarity in any way, but I will happily offer a deal - you say specifically what sort of similarity you think you need, and I will see if I can explain or accommodate it within chain-of-causality. In addition, I can’t let this particular statement go without noting the irony of you chiding me for not providing details! "... I deny this is so -- causality can't rescue your position; it can't make there be some like-ness that is somehow both material and yet does not involve arrangements of atoms that are similar, which we've already ruled out." Frankly, I have no idea what you are saying here, but whatever it was, I suspect that it is moot now that I have clarified my position. If you think it is still an issue, could you provide more details? Finally, I don't think there's anything to say about the conclusion - obviously, I'm not persuaded that it is correct, for all the reasons above. There is, however, one more thing that I want to go back to, as it pertains to this discussion as a whole. You have acknowledged that your claim is very limited, in that you are not making any claim as to what this likeness may be like. One of the consequences of it being limited in this way is that no conclusion of your arguments can rise to the level of being taken for a fact - a justified true belief - until you can say enough, about what it means to say that thoughts have a likeness to reality, for that premise to be regarded as justified (to be clear, this is a necessary but not sufficient condition.) You cannot avoid critical analysis of your thesis by not making affirmative statements about what it means, as the absence of such claims is one of the bigger problems with it. If you remain aloof about this, anyone evaluating your claim on its merits would be fully justified in being equally aloof about whether your argument is sound.
