Jim Stone<\/b><\/a>: “Epiphenomenalism about mental properties isn\u2019t necessarily false but I think the case against it is virtually overwhelming”<\/i><\/p><\/blockquote>\n
The only way to make a case against epiphenomenalism (construed as the innocent plaint that we do not seem to be able to give a causal explanation of how or why we feel) is to give a causal explanation of how and why we feel (without resorting to telekinesis, which is false).<\/p>\n
JS:<\/b> “I focus on qualia.”<\/i><\/p><\/blockquote>\n
I agree with you that “it\u2019s silly to argue about words,” so allow me, for heuristic reasons, to substitute in all my quotes from you, below, my preferred, straightforward anglo-saxon term, “feelings,” understood by all, for the quaint neologism “qualia” favored by some philosophers. I think it helps forestall certain common forms of question-begging:<\/p>\n
JS:<\/b> “1. If [feelings] were black holes in causal space… we wouldn\u2019t know they existed.”<\/i><\/p><\/blockquote>\n
Translation: If we didn’t feel, we wouldn’t feel. Agreed.<\/p>\n
(Ontic variant: If there were no feelings, there would be no feelings. Agreed.)<\/p>\n
JS:<\/b> “Of course we do know [feelings] exist and it isn\u2019t a matter of abductive reasoning or inference. We know that [feelings] exist because we are directly acquainted with them.”<\/i><\/p><\/blockquote>\n
I feel (when I’m feeling) therefore I feel (when I’m feeling). Agreed. We owe as much to Descartes (“sentio ergo sentitur<\/a>“).<\/p>\n
JS:<\/b> “Direct acquaintance, on any plausible account, involves causal powers to affect the mind by the object with which we are so acquainted”<\/i><\/p><\/blockquote>\n
Agreed. I’m just waiting for the “plausible account” of how and why.<\/p>\n
(I will let the more equivocal phrase “affect the mind” slip by, though it really just means that gazing at things makes me feel something, namely, what it feels like to see them. In other words, it is just the restatement of the unexplained correlation between functing and feeling. I have no problem with accepting the fact — since it’s obviously true — that the cause of my feeling is something that happens to, and happens in, my brain. But the explanatory gap is in explaining how and why that something that happens is a felt something<\/i>, rather than just a functed<\/i> something. The fact that the felt something does happen is not in dispute. Nor is it really in doubt that it is the brain that causes what would otherwise just be optical transduction to become, instead, or in addition, felt seeing, somehow<\/i>. The part that is not only in doubt but certain is that no one has explained that “somehow” — i.e., how or why the optical transduction is caused to become felt seeing. Moreover, perhaps going a bit beyond what is certain, I add that there are good reasons to believe that it is not even possible to explain it, in the usual causal\/functional way that everything else is explained, without resorting to telekinetic<\/a> causation, which does not exist. The problem is already there in trying to explain how the brain causes feeling, and even more pressingly there in trying to explain how feeling causes doing. There would be no problem at all if all doing and doing-power remained exactly what they are, functionally, but there were no feeling, just unfelt functing.)<\/p>\n
JS:<\/b> “2. It seems perfectly evident that [feelings] play a substantial causal role in our lives.”<\/i><\/p><\/blockquote>\n
Feelings certainly play a substantial felt causal role in our lives. But I hope you will agree that a felt cause is not necessarily the same as a real cause.<\/p>\n
It is also true that the (unproblematic) external objects and internal functional states that appear to be the (unexplained) causes of our feelings (via the brain) play a substantial causal role in our lives (felt and unfelt).<\/p>\n
But it is the causal status and role of feelings qua feelings — rather than just as the side-effects and correlates of unproblematic external objects and internal functional states — that is under scrutiny here: How and why are they felt? Not whether they are felt to be causal (they are). Not even whether they are caused (they no doubt are, somehow). But how and why they are felt rather than just functed (to the same functional effect)?<\/p>\n
JS:<\/b> “on the face of things the causal role of [feelings] in our lives is is one of the phenomena an account of the mind ought to preserve.” <\/i><\/p><\/blockquote>\n
Indisputably.<\/p>\n
But alas, this welcome account is faced with an awkward explanatory gap…<\/p>\n
JS:<\/b> “3. If [feelings] have no causal powers, they couldn\u2019t have been selected for by evolution”. <\/i><\/p><\/blockquote>\n
So one would think.<\/p>\n
So explain to me how the Blind Watchmaker (a pure functionalist, if there ever was one!) was able to select the Darwinian survival machines that felt, and reject the ones that only functed: Was he reading their minds? How? Why? (Evolution is surely as non-telepahic as it is non-telekinetic…)<\/p>\n
