The need to assume such a principle, that plasma employs semiosis, which is contrary to the evidence, points to bad metaphysics. — Metaphysician Undercover
I can't see how that can be the case without there being mind in the first place. When Peirce says that 'matter is effete mind', this does seem to be his meaning. As we've discussed, he seems to have acquired this idea from Emerson, Schelling, Kant, and others of that ilk. He is also invariably categorised as an idealist philosopher - actually as an objective idealist. — Wayfarer
So, the reader or interpreter of symbols, and thus of form and matter, is herself exhaustively constituted by matter/symbol ('symbol' here understood in the broadest sense as inclusive of sign, icon and symbol). Matter/ symbol reads itself? — Janus
The pansemiotic claim is tricky. I readily admit that it is a speculative project. So I will try to explain it better.
Straightforward semiosis is no problem. Humans use language to regulate social behaviour. It is just taken as obvious that language is a symbolic activity where tokens or symbols are used so that a realm of ideas can interact with a world of material dynamics.
Then Peirce sought to define what was the "core machinery" by which language could gain this meaningful "modelling relation" with the world. He drilled down to describe it in epistemic terms - understanding semiosis as the logical act of reasoning. So words have their purchase over reality because of a triadic sign relation. There is the world. There are the signs we form that "represent" it. There is then our habits of interpretation - the understanding we form by virtue of a sign-mediated relation with the world.
This is pretty much straight linguistics. It is a more sophisticated take than Saussurean semiotics in being triadic rather than dyadic. Peirce makes the Kantian point that the sign stands between us and the world. And so the sign represents not just the world, but also "us". The signs we form are inherently "self-interested" in that they represent the world in terms that are pragmatic or purpose-imbued, not nakedly of "the thing in itself". So the mediating level of sign - the "umwelt" that forms our "state of sensation" - is a representation of our state of being, our wishes, desires, interests, and history, as much as it purports to be a representation of the world beyond.
Another important wrinkle of the Peircean approach is that he saw sign as itself having an immanent developmental story. It begins as merely a potential relation - an icon. Develops to become an indexical sign. Then only ultimately reaches full-fledged status as a symbol. So first it is just a picture that can be recognised as involuntarily predicting some state of affairs. Then it becomes a more deliberate pointer - like a dog's wagging tail or a road sign. Only finally is there a full "epistemic cut" where the relation between a token and what it stands for becomes arbitrary and therefore a wholly voluntary, or "self-produced", communicative act that requires interpretance.
The word "apple" - either as a spoken sound or scribbled writing - and an apple have no necessary connection. Therefore the habit of understanding the physical mark to mean something becomes entirely "mental". Mentality begins definitely at that point.
So semiosis is straightforward and uncontroversial. Peircean semiosis is pragmatic as it is clearly tied to an epistemology of the self. The sign relation makes us as much as it makes the world that exists for us. It is an understanding of language use and human reason that gets Kant and manages to accept the key part of idealism without rejecting what matters about realism.
Then armed with an understanding of the triadic semiotic relation, we can see that it applies to life as well as to mind. We can see that brains use neurons to encode the world, form a modelling relation with the world based on sign. And the immune system is semiotic. So is the gut. They use a system of molecular receptors to decide what is self and what is non-self. Then the genes of a cell are clearly a coding machinery, embodying a model of the self in a world in their ability to interpret the signs they are getting in terms of the states of being they are trying to achieve.
So science has no problem seeing Peircean semiosis as a completely general account of life and mind. It describes a triadic "world-making" relation that run all the way from the first biological act - the first time a molecule functioned as a message - right up through complex bodies, to bodies with brains, to brains with language, to languages that were logical, mathematical, and capable of "total reasoned abstraction".
Then we can start to talk about pan-semiosis. This would be a continuation of the story beyond the kind of complexity we recognise in living and mindful systems.
Now Peirce did attempt this with his Cosmological semiotics. He described the triadic relation in a way where the Universe's coming into being as a realm of definite law could be understood as the psychological development of habits of regulation.
As Wayfarer notes, late in life, Peirce did become overtly religious - or at least "spiritual". But how seriously should we take that, given that his semiosis arose out of a scientific psychological model, and then out of a logical generalisation of that psychology?
Wayfarer keeps returning to the one quote that is his convenient hostage to fortune. But it is unfair on Peirce to read his incredibly broad-minded approach to a "philosophy of nature" in such a narrow and self-serving fashion. His semiotics provides an intelligible bridge between the divided camps of physicalism and idealism. To claim Peirce is then just an idealist is cheap and slipshod.
Anyway, Peirce's cosmological semiotic is more a "logical poetry" than a physics-based theory. It was inspired by the dawning thermodynamic understanding of his time. It did foreshadow quantum physics in its emphasis on indeterminism and the observer-depend nature of reality. Peirce even foreshadowed general relativity in proposing that an evolving universe might show curvature over cosmic measurement scales - his early career as a scientist meant this kind of measurement issue was exactly his forte.
So the context of Peirce's cosmological argument was that he was fully up to date with the science of his age. And he could see that the Newtonian notion of an eternal Comos with fixed God-given laws was pretty "unnatural" in a world where mind, reasoning, growth and evolutionary development were a central fact.
Thus Peirce created his theory of an immanent pansemiotic cosmology where hierarchically complex existence was formed via a "universal growth of reasonableness".
The story went that in the beginning was a Firstness, a bare potential of spontaneous fluctuation or tychism. The sporting of absolute chance. So there was a vagueness with no particular matter or form. But then that meant there was nothing to prevent accidental fluctuations that were some kind of context-less event - a bare action with a direction of some kind.
Then if something could spontaneously happen once, it might happen again. With nothing preventing it, you would have a host of fluctuations and so now the Secondness of some more definite act of interaction. One fluctuation would react with another. The possibility of a history of collisions, deviations, agglomerations, deformations, etc, could start to form.
Then once you have this random play of interactions, regularities would start to emerge. Over time, a history would start to exist in a way that became generally constraining. A habit or state of equilibrium would result.
This was straight thermodynamcs. Inject a hot particle into a tepid gas standing at equilibrium and the particle will eventually knock about in a way so that its momentum converges towards the general average. A cold particle will get bumped and jiggled to heat it up to the average. So the laws of nature can be understood as nothing more than the kind of rational patterns that emerge as the "sum over histories" of a set of interaction - a prevailing statistics.
The Universe would have been born of unbounded fluctuations - the primal chaos of a Firstness. But it then could not help but to self-organise in the fashion described by both thermodynamics and quantum physics. The first random actions might have any direction, any strength. But then their interactions would thermalise them, tame them, bring them towards some common equilibrium that gave the Universe an overall direction or developmental flow. A collective history become a collective constraint. Existence becomes a single universal habit.
So Peirce's semiotic - the triadic system of Firstness, Secondness and Thirdness - is the ontological version of his epistemic triad of world, sign and interpretance. Semiotics in the linguistic or psychological sense is about the symbol~matter distinction - the epistemic cut by which a realm of ideas can come to regulate a world of material dynamics. Now Peirce was using the same causal machinery to explain the physical world as if it had "a mind".
The metaphysical question becomes how much is this just a nice analogy and how much a proper theory of nature and existence? So pan-semiosis would be showing how it is actually a theory more than an analogy.
Well if we look at the way physics went after Peirce's time, we can see how the observer issue moved back to centre stage.
Newtonian physics was reductionist in being a realist physics based on just observables. Basically, humans believed they were looking at reality with a God's-eye view of it. There was no issue about where to place the epistemic cut between the observer and the world observed. Naive realism applied. Then came Kant to show the psychological problems inherent in that. And then Peirce - whose career as a scientist was all about science's fundamental issue of how to make an "objective measurement".
But the observer issue became central to modern physics in the 20th century. Quantum mechanics showed something really "weird" was going on as humans just couldn't seem to disentangle themselves from the world they wanted to measure. But relativity was just as weird. Again, an observer was only relatively disentangled from what they meant to observe. And even eventually thermodynamics returned the same metaphysical shock. Chaos revealed the initial conditions measurement issue for describing dynamics. The Newtonian approach to entropy turned out to be also the inverse of a measurement of observer uncertainty - the metaphysical twist that turned physics towards its new information theoretic perspective.
So nature really seems to be trying to tell us something. To understand it, we need a semiotic lens. A fundamental theory of nature will have to include the observer along with the observables in some formal fashion. We can't pretend to have a simple God's-eye view like Newton. The "mind" itself must be reduced in some completely general fashion. And Peirce offers the most general story on how observers and observables - selves and worlds - are developed through the mediation of the third thing of the signs that connect them.
So the metaphysical project is clear. Physics is already charging down that road. But there are still some paradigmatic shifts in thinking that are a long way off for virtually everyone. We can't "get" pansemiosis until we have made some quite significant changes in orientation.
The key one that currently interests me is the importance of material instability to the whole picture.
The usual assumption is that the material part of the story must be about stability, definiteness, concreteness, persistence. It just make sense that the material foundations of being must be sturdy for the more delicate business of symbolically-encoded complexity to arise. You definite parts to start constructing elaborate wholes ruled over by rather immaterial ideas or purposes.
But the recent biophysical revelations about the molecular basis of life show that a cell depends on its fundamental instability. All its molecular parts must be in danger of falling apart to make them in fact easily controllable by the cell's information. So life seeks what was, back in the 1980s, called the edge of chaos, or self-organised criticality. It is materiality at its most fragile or labile that is "living enough" to become the robust foundation of living processes. As what is poised on the point of falling apart is also poised on the point of falling together. All the molecular chaos needs is a steadying genetic hand - enough of a signal pointing in the "right direction" that is the falling together.
So biosemiosis is about this central understanding. Life depends on fragile material. It wants a material foundation so labile that it can then become "completely regulated" by the ideas and purposes remembered at the informational level of the genes. The job of stabilising is owned by the system's information. The mind of the cell - as a collection of learnt habits - is the source of its long-run stability.
So consciousness is often thought of as being centrally about spontaneous creativity and maximum fluidity. But neuroscience has also come to realise it is the same story of a regulation of uncertainty. The mind is centrally about habit formation. And it exists to stabilise a collection of useful physical or behavioural interactions with the world.
Any other model of "the mind" - like a spiritual or freewill one - is fundamentally flawed. Even the linguistic human mind is all about creating a social and cultural stability. Humans - as animals - are a bunch of unstable degrees of freedom. But language is society's way to bind humans into collective organisms. As we see in modern society, personal instability is promoted - we are brought up to imagine that anything might be possible in terms of how we might behave. And then that individuated instability becomes a potent energy that society can harness - keep nudging just enough so that we collectively fall together in some enduring direction while always seeming to be on the verge of catastrophically falling apart.
OK, this story of semiosis as "the stable realm of symbol regulating the instability of material reality" works for life and mind. Then pansemiosis would extend that to the physical world in general.
And again, this is simply just the view that physics has been backing into for about 100 years now. Quantum mechanics tells us the Cosmos is fundamentally indeterministic and then needs "a context" to collapse its uncertainty. What creates material stability is thermal decoherence. And this context, this history, is then "written into" thermal event horizons. The holographic principle shows that the physics of "material events" is ruled by the "information content" that can be encoded on the "surface" of a physical region of spacetime.
So it sounds odd if - as MU does - we try to understand pansemiosis in terms of the Cosmos literally having some kind of mind that is interpreting physical events as symbolic activities. This starts to sound like the pan-psychism of Whitehead and his prehending particles. Atoms are reading each other as signs rather than just colliding like material billiard balls. Spooky, hey?
But still, modern physics actually has rejected the material billiard balls now. Two particles crash into each other and recoil in some far less material way. In quantum language, the collision starts to become a blizzard-like exchange of virtual particles - tiny messages that you are getting too close to me and need to start backing off. The pressure of exchanges increases until the other particle is forced to veer off.
And then as we really step back to a quantum field description, the reason why two particles bounce off each other becomes just some kind of statistical effect - an completely informational one. The probabilities of where the two particles ought to be becomes exponentially "anywhere except as close as this". Even the last material connection of virtual particles has vanished. The quantum picture has switched to one of pure sign. All the physics can properly describe is the abstract image of a completely generic wavefunction. Somehow an observer must then intrude "physically" to tell us what actually happened on this or that particular occasion with the same kind of probabilistic set-up.
So I accept that pan-semiosis sounds weird. But reality is weird! And pan-semiosis is a metaphysics weird enough to account for all of the phenomena that science is most concerned about. It is a metaphysical machinery that can span the gamut from the quantum to the cosmic, the physical to the mental. Even if physics ends up calling it something else, it will still be pansemiotics as Peirce originally envisioned it. And it is quite nice that in theoretical biology at least, a conscious connection to Peirce has been forged in the public embracing of "biosemiosis" over the past 20 years.
