I'm leaving for a week in the backwoods, so it will be more like next week before I reply, as there are many things here to correct. One thing I did n...
I see that you still have no clear idea what my argument is, largely, it seems, as a result of your attempts to paraphrase it into something that you ...
firstly. let me say that I have come to agree with you that I should say something about what physicalists assume about color vision, though it will n...
There is nothing wrong with introducing a new premise into a discussion. If doing so were wrong, then we should reject your introduction, in your late...
There is alternative way of looking at your argument, by introducing premise 0: Everything that anyone could know about color vision is physically-enc...
Indeed it is, and on the contrary, you seem to have overlooked (or, as you would put it, "are confused about") the relevance of this issue. It goes ba...
I am glad that this, at least, is obvious, but there is an implicit question here: suppose we have some system having information on account of being ...
I did, and I see that it can be read in the light of these being synonyms. I assume, therefore, that you have no objection to 'can be stated' being su...
You say I am mistaken in saying that it is a premise of yours that Mary learns something from seeing colors, but your premise 7 is that "Mary gains ne...
I am puzzled by this. The claim that Mary learns something from seeing colors is a premise of Jackson's argument, and yours too, if I am not mistaken....
The SEP is an excellent resource, and in section 2 we have a discussion showing that it is not straightforward to find an inverted spectrum scenario t...
I think we should reset this discussion, and start over. Firstly, let's get rid of the ambiguous phrase "physical knowledge", and replace it with "kno...
And in quoting me, you left off the very next line: Later on, I wrote: so it is not as if I am imputing straw-man arguments to you. The only invocatio...
Ha! this is just a long-winded way of attempting to hide that you are failing to refute what I have been saying: people generally agreeing on categori...
That's my point about your argument - you are making assumptions - assumptions that say "our experiences have these similarities". Equally for your as...
Firstly, thanks for taking the time to put together a well-argued case. I cannot imagine why you think I am confusing L1 and L2, but there is nothing ...
Nevertheless, I think we can trim the range of issues to be covered. Personally, I don't think your concept of complete physical knowledge is incohere...
Jackson (and also you, I believe) are actually arguing that Mary's knowledge, at the time of her release, is incomplete - but any response along these...
It is clear that before we can complete the discussion of your argument, we have to resolve the issue of what would count as an effective counterargum...
I think it is sometimes called 'yellow' (if I am recalling that usage correctly) because it is a variant of the more common green opsin, with a spectr...
The question of who bears the burden of proof (or accounting) is not always clear-cut, but in this case, I think Churchland's response, especially whe...
I think I do, and I think we are talking at cross-purposes. You are saying that these differences exist, and I am saying that they are second-order ef...
If it is not knowledge, then Jackson's argument fails, because it depends on her gaining knowledge that is not in the set of "all the physical knowled...
Well, if you haven't reached the conclusion that physicalism is false, then you have not completed your task of, as you put it, circumventing Churchla...
Purely by chance, I noticed that you added a postscript to your last-but-one post after I had replied to it, in which you offered some sort of respons...
The only thing that was to the point in your previous-to-last post was that you finally put up an argument (or, rather, the outline of one) in support...
All the evidence to that point (notably, the absence of any argument) supported it.Whether the situation has improved with your latest post remains to...
Essentially yes, but... Firstly, we must recognize that people have been talking about colors for millenia, and, for the most part, doing so without h...
Let's cut to the chase, and start with one issue that seems to render everything else moot - your conclusion: This seems to come back to what I said e...
I think that most proponents of that view would say that she would be able to remember colors, compare colors, and even perform Hume's task of imagini...
Thanks! I am surprised by the lack of attention that Churchland's paper gets, as, in my opinion, he has identified the fundamental flaw in Jackson's a...
And often the null hypothesis is right! We seem to be agreed, then, that this hypothesis is both plausible and possibly correct. Firstly, I see that t...
@"Harry Hindu" It doesn't approach being a proof, but, IMHO, it is a plausible hypothesis. Per my earlier post, I would not propose that everyone's ex...
There are some who disagree, but personally I agree that subjective knowledge is real. What makes it subjective, in my opinion, is that only I have th...
I think I can give an analogy which shows why this approach is not useful. Suppose we have two different computers; say an ARM device running Linux an...
Jackson claims to have proven that physicalism is false, so physicalists can logically assume that physicalism is correct in any counter-argument - it...
This is actually the essence of Paul Churchland's response "Knowing Qualia: A Reply to Jackson", in which he shows that Jackson uses the term "knows a...
@"Pantagruel" My go-to example for this sort of thing is the theory of evolution. It is one of the most powerful and influential scientific theories t...
Thanks! It occurred to me just now that a simplified definition along these lines might be that a justification has to be a valid argument that is mor...
There are close parallels with the soundness of an argument here, and the no false premises response, which I agree is a partial solution, is treating...
No, I don't see a negative self-reference that has any relevance to whether subjective experience can be explained. Nor do I see any any subjectivity....
Well, we'll see - or not. With regard to your example, it is not clear to me what your argument here is - in fact, I cannot even see what your conclus...
It's not entirely straightforward to come up with a definition of what's alive and what's dead; there is some disagreement over whether viruses are tr...
I think you are alluding to the Lucas-Penrose argument aganst the possibility of there being algorithms that produce minds. If so, that is a separate ...
Yes, I think you are on the right track here, though it may be leading in a surprising direction. Firstly, there is no difficulty with 'it is possible...
I had some more thoughts on conceivabilty vs. possibility. Most philosophers accept possible-world semantics for dealing with questions of possibility...
Thanks for saying that. It is easy to get carried away whan defending a point of view. I do, and I used to do it a lot more; I have to make a consciou...
I think we have reached the point that we can agree to differ over whether or not there is something special about understanding, because we are appro...
