Do you know what a contemporary panpsychist would say about selfhood? If there are tiny consciousness units or vast waves of it, where is knowledge of self? Is selfhood emergent? Or is it in the tiny bits? — frank
I'm not very well read at the moment, sorry. I haven't kept up that well with developments.
There are two camps (among others) among panpsychists IIRC. One camp are the micropsychists (or smallists) who think that there is consciousness everywhere there is matter, because all matter at the level of fundamental particles possess a unitary consciousness. So quarks and electrons and leptons or whatever are conscious. So these panpsychists don't think that literally everything is conscious, just that consciousness is everywhere because tiny things are everywhere. At exactly which points in the complexification of matter consciousness arises again as a unitary mind (i.e. a self, a centre of experience) I'm not sure about. Is it at the level of atom? The organic molecule? The cell? The neuron? The brain? Or what? Smallism seems doomed to arbitrariness to me, and very vulnerable to all the usual objections: How do experiences 'sum'? This is still a kind of emergence so why not just have emergence from non-conscious stuff? How do we avoid the arbitrariness? No doubts smallists have their answers, but one way out of this is to drop smallism and opt for....
...Cosmopsychism, which could be called 'biggism' I suppose. This says we start with the universe as a whole as the primarily conscious entity. I'm not sure about that either, although I prefer it to smallism. I might be a cosmopsychist, I'm not sure. Need to read up about it. There is the possibility here of making a fallacy of division (the parts are conscious because the whole is) as @TheMadFool will be alert to. But it's likely that other arguments are made which do not fall foul of that.
For a theory of what makes a 'self' or private unitary centre of consciousness is a very interesting question and I don't know the answer to it. However we could plug in various functionalist theories of consciousness here, but rebranding them not as theories of consciousness, but theories of the self. For example, the Integrated Information Theory of consciousness (Tononi and Koch) is a really interesting idea, except it is wrong because it is a functionalist reductionist theory of consciousness. It says consciousness and integrated information are one and the same thing, which is just wrong. Consciousness is consciousness and integrated information is integrated information. Instead it could be much more profitably rebranded as a theory of the self. That is to say, any entity that integrates information is an individual. Everything (however arbitrarily defined) integrates at least 1 bit of information (I'm winging it here - it's ages since I read the papers) so everything is a centre of consciousness. However experiences start to get interesting when more than 1 bit of information is integrated. And when we come to brains, which integrate large amounts of information, we get the rich conscious lives we currently have. I think it's an interesting possibility.
In general I think there is a massive confusion which dogs both philosophy and science, the confusion between consciousness and identity. For example, when people take an anaesthetic, it is said they have
lost consciousness, which is fine for everyday talk of the kind that @Banno likes. But if we take this a little more carefully, we might ask "What exactly is lost? Could it be identity that is disrupted, rather than a loss of consciousness? Experientially, for the person, wouldn't those two things be the same?" On one, identity remains, but consciousness is lost; Asil has no experience. The other, consciousness remains, but identity is lost; Asil has no experiences because Asil, defined as a functional unity, no longer exists; instead, lower level systems which do retain (complex or simple) functional unity are the ones having experiences. When Asil wakes up, what has happened? Has her consciousness rebooted? Or has her identity rebooted? It's hard to tell experimentally. But we tend to assume it is consciousness that has rebooted, but this is not a safe assumption. I think it's much more likely that identity is disrupted.
