Panpsychism - Galen Strawson on consciousness

I was browsing the wonderful Philosophy Bites yesterday and listened to Galen Strawson on Panpsychism*.
*Panpsychism is the doctrine that mind is a fundamental feature of the world which exists throughout the universe
I've mention Strawson's ideas before, and my big objection to his approach is that he denies emergence as an explanation of how you can get consciousness (experiential things) from non-experiential matter.  He - briefly - addresses that point head on in this philosophy bite, though I'm not entirely convinced by is argument and yesterday's post about Integrated Information Theory (IIT) is an example of a way to approach the emergence of consciousness (not that I found IIT entirely convincing either).

However, this, from Strawson, at least deserves pondering:
Why have we simply assumed that the physical is in its fundamental nature non-experiential. What's the evidence for that idea? And I'll give you the answer because it's mathematically precise, there is zero evidence for the existence of non-experiential reality anywhere in the universe. So why simply assume that the fundamental things are non-experiential and then cause this huge problem for yourself which is the problem of how do I get the experiential from the non-experiential? It's much simpler, simply to suppose that there is experiential reality already there, right at the bottom of things.

Galen Strawson on Panpsychism (Starting at 4:42)
The point is that: "cogito ergo sum"; we know from our own experience that the experiential exists, it is non-experiential reality that we are taking on trust.

Information & consciousness

One of the reasons I'm so interested in information is the link to consciousness. Consciousness is surely on the front line of our struggle to make sense of the world, it is one of the really big problems. See what Dennett wrote in 1969:
THOSE who are convinced of the futility of philosophy are fond of pointing to its history and claiming that there is no progress to be discerned there. In no area of philosophy is this claim easier to support than in philosophy of mind, the history of which, when viewed through a wide-angle lens, appears to be a fruitless pendulum swing from Descartes' dualism to Hobbes’ materialism, to Berkeley’s idealism, and then back to dualism, idealism and materialism, with a few ingenious but implausible adjustments and changes of terminology. The innovations of one generation have been rescinded by the next so that despite a growing intricacy of argument and a burgeoning vocabulary of abstruse jargon, supplemented in each era by the fashionable scientific terms of the day, there have been no real and permanent gains.

The question that defined the pendulum is what the relation is between mind and body, and the problem that set the pendulum in motion was Descartes' dilemma of interaction. If, as seems plausible at first glance, there are minds and mental events on the one hand and bodies and physical events on the other, then these two spheres either interact or not.

"Content and Consciousness", D. C. Dennett, Routledge & Kegan Paul 1969
Of course since that was written 40 years ago it could all of changed - maybe the problem of the mind has been solved, but I don't think so.

Information surely lies at the boundary of these two spheres.

In the London Review of Books there was recently a review of a work by the philosopher Galen Strawson [1]. There's lots of really intriguing ideas in there, like the suggestion that
...the subjective experience of the self does not require that it persist beyond the lived present, which lasts for less than a second
so not only am I not that same person when I wake up in the morning as the person who went to sleep the night before, but I am a different person from one second to the next.
Not only does the self not persist across gaps in consciousness; it also doesn’t persist across the shifts in the content of consciousness that occur constantly in the course of waking life.


But that's not really what I wanted to highlight here. What I want to raise (which I have just discovered was not in that LRB article, but in an earlier one [2]!) is Strawson's panpsychism:
Strawson ... stands revealed as a panpsychist: basic things (protons, for example) are loci of conscious experience
Having been reading about native American religions over the Christmas it is quite nice to come across a (modern, Western) philosopher with an argument that might support the idea that trees, rocks and rivers might be conscious, but it is a lot to swallow and I'm not quite there yet!

One of the steps in the argument that leads Strawson to panpsychism is that he doesn't believe in emergence. So, since we are conscious, so too must the stuff we are made of also be conscious. And since that stuff is the same stuff that trees, rocks and rivers are made of, so too might they be conscious. Well, I think that is where I can point to a straightforward disagreement: I do believe in emergence. I think information is an emergent property. The information carried by the bits in a digital communication channel is not in the bits, but 'emerges' from the order in which they are put together.
