PhizzicsPhan said:Apeiron, I will respond to your additional questions, believe me. But please humor me with this line of questioning a bit longer. Where does the "epistemic cut" occur? With unicellular life? Viruses? Prions? Self-replicating RNA? Is there an exact moment that life emerged phylogenetically? And is there an exact moment in each life form's development that it transitions from abios to bios ontogenetically? If so, what is that moment and why?
Do you think viruses and prions existed before life began? If you agree this is unlikely, as they are parasitically dependent on life, then we can rule them out as a foundational issue. (You could have "less than life" developing from life proper, if there is life around to hijack).
And the actual beginning is unknown. It left no record. So we can only make educated guesses. We can't bring it forward as evidence in this argument, and if that is what you are asking for, it is not a legitimate tactic. Talking about what might have been the case might help the argument along, but it is not a make or break part of it.
So you will have to tell me what it is about the epistemic cut, matter~symbol, dividing line that you object to.
Asking me to take you back to the point at which it first happened is an interesting question, but a sidelight. If we know it is what happened.
But because it is interesting, my answer would be that the origin of life was all about the "constraint of dimensionality".
So ordinary law-bound dynamics takes place in generic environments. A chemical reaction takes place in a solution, a 3D space at constant pressure, temperature, etc. And so its rate is dependent on these globally rigid or holonomic constraints.
But changing those constraints changes the rate. So in a rock-pool heated by the sun, flushed by the sea, you get imposed patterns.
When a collection of hydrophobic fatty molecules form up into a globular sphere, that again shrinks the dimensionality for chemical processes. Likewise when the processes are confined to a thin water film as on the spur formations of clay.
So first we have to recognise the importance of dimensional constraint as a way of locally changing the rate of generic chemical processes. And a theory about the origins of life would be seeking these kinds of stories. Which indeed they do.
And then we can show also that symbolic systems lie at the very end of the spectrum of possible dimensional constraint. Shrink down the space of a reaction and it goes from 4D down to 1D and then 0D. It becomes a serial code - like genes and words. And it becomes something novel because once removed from the hurlyburly of generic dynamics, serial codes have the newfound freedom to objectively measure that hurlyburly and start to control its initial conditions employing flexible or non-holonomic constraints.
So you can see the nature of the argument? The reason the origin of life seems such a puzzle is that it is usually framed as the surprising emergence of two critical things at the same time - metabolic processes and rate-controlling codes.
But I am unifying those two kinds of emergence as one. They are both the result of the same process of dimensional reduction. Metabolism can arise spontaneously as generic dynamics wanders into some more dimensionally constrained regime (like a crystalline clay formation with its films of water). And codes can arise spontaneously for the same reason.
This is also my view of the emergence of speech in homo sapiens. The development of vocal cords for other reasons (song like emotional/social calls perhaps) placed a serial constraint on utterance. This led to a rapid development of symbolic speech. Once vocalisation had wandered into a sufficient degree of constraint by "chance" - evolution of a restriction for other reasons - symbolic speech became inevitable.
([EDIT] I should add that the semantics~syntax issue is just as confounding for evolution of speech theorists as the metabolism~code one is for origins of life theorists. And this is the way out of that issue.)
So as you can see, having a strong definition of life vs non-life leads on to a richly structured view of biology and mind science generally.
On the other hand, panpsychism as a model of reality just appears to shuffle the fundamental questions around.
Can't find consciousness popping out the top where things are maximally complex, well let's guess that it instead exists down at the bottom where things are maximally simple.
