Happy Easter! I hope people are managing to enjoy some leisure and pleasure in these unique circumstances of lockdown. One thing I did was to watch this video of Daniel Kaufman and Massimo Pigliucci raising some objections to the (very different) views of Keith Frankish and I. I enjoyed this and I’m very grateful to Daniel and Massimo for thinking about my work. I’d like share a couple of quick responses.
My first issue is that they reject my version of panpsychism without really articulating what it is. This is especially striking when they discuss the response I gave to Sabine Hossenfelder’s blog post critiquing panpsychism in my public exchange of letters with Massimo. At 28:29, Massimo says that I respond by saying that ‘panpsychism is not about physical properties as we understand them.’ This is at best a massive oversimplification of my response to Hossenfelder and is arguably misleading. Daniel then goes on to criticise me in very strong terms (including accusing me ‘either unresponsive or obtuse’ on twitter…I thought we’d got on on twitter!) for not appreciating I need to offer an account of how certain properties can be ‘elemental properties of matter but not material’ (he contrasts me to his former supervisor Katz, who wrote ‘a whole book’ articulating a view according to which there are entities with both abstract and concrete properties).
The thing is, I do have an account, which I have written two books (one academic and one popular) defending. And that account is built on upon two further books, one by Bertrand Russell and one by Arthur Eddington (or rather, it’s based upon those books and the huge literature that they have spawned). The idea is that the properties physicists refer to – mass, spin and charge – are identical to forms of consciousness, and that we can make sense of this identity because physics only describes the behavioural properties of physical properties and is silent on their intrinsic nature. Now there are all sorts of ways you can criticise that account, and I’m sure some will doubt it’s ultimately incoherent. But I find it bizarre that Massimo and Daniel don’t even describe my view but instead dismiss me on the grounds that I don’t have a view.
Later in the discussion, the issue of empirical evidence comes up. Massimo correctly reports that I don’t think that a case can be made for panpsychism over materialism on the basis of empirical evidence. However, he then goes on to say that when he challenged me on this, I said that ‘the very asking for empirical evidence assumes a physicalist view’ (38:20). This is something Massimo also pressed in this recent popular article, suggesting I put metaphysics before epistemology and that I provide no epistemological justification for my view. I’ve looked back at the letters I wrote, and I have no absolutely no idea how Massimo is reaching this interpretation of what I said.
In fact, for better or worse, I do have an argument for the seemingly odd claim that we have grounds for believing panpsychism despite not having straightforward empirical grounds for believing it. My reasoning is as follows. We tend to think of the aim of science as accounting for the data of public observation and experiment. The trouble is, consciousness is not known about in this way. We know that consciousness exists not on the basis of observation and experiment but on the basis of our immediate awareness of our feelings and experiences. Hence, if we religiously follow the dictum ‘only believe in the things that are known about on the basis of public observation and experiment’, we’d have no grounds for postulating consciousness at all (the illusionists, also discussed in this video, are wonderfully consistent on this point).
Therefore, if we want a science of consciousness, we need to expand our conception of the data science needs to account for. We need to be looking for the simplest theory that can account for both the data of public observation and experiment and the first-person reality of consciousness. I think panpsychism is that theory (partly because I think it can be demonstrated that materialism can’t account for consciousness), and this constitutes the basis of my epistemological justification of it.
Now there are all sorts of things you can attack about the above position, and the very interesting claims Daniel and Massimo make later in the discussion could certainly be used in this way. But if you’re going to discuss my case for panpsychism surely you should at least say what that case is. And the stuff Massimo attributes to me about ‘the request for empirical evidence assumes physicalism’ is wild misinterpretation.
Later in the discussion, Daniel and Massimo agree that idealism is empirically equivalent to materialism, and Daniel mocks Samuel Johnson for trying to refute Berkeley’s idealism by kicking a stone. There is a deep irony here: the Russell-Eddington inspired panpsychism I defend is also empirically equivalent to materialism, which makes Hossenfelder’s post the contemporary equivalent of Johnson’s stone-kicking. Furthermore, given that Massimo accepts that materialism and idealism are empirically equivalent, surely by his own strict empiricism he should be agnostic about which view is true. Perhaps he is, but one doesn’t get that impression.
I’m sure there’ll be lots of people who watch this video and say, ‘Oh my god, Goff defends a view without any evidence, he’s such an idiot.’ But I think anyone fair-minded who’s read, watched, or listened to anything I’ve said on this, whether they agree with me or not, will recognise that my view is not being charitably represented here. In fact, it’s barely represented at all.
