For instance, is human philosophy conceived of as something like reality's self-knowledge? — jas0n
Something like that is surely the case. But that is also too flowery language.
What does it mean for humans to ascend to a mathematical level of abstraction in semiosis? As science, it has resulted in us trying to de-subjectivise our inevitable first person point of view to recover the objective third person, or God's eye, point of view. Or better yet, following more insightful approaches like Nozick's Invariances, we seek to dissolve our highly particular view of the world in the mathematical acid of universal symmetry.
So to the degree the world is understood as physical - some blend of fundamental material accident and fundamental constraining structure - we can hold a mirror up to that. We can construct a metaphysics that sees the world in this way. And pragmatically proves itself as a correct view because it offers us control over all the physics involved.
Thus it is not about "knowledge" in some passive Cartesian representational sense. It is instead knowledge in its enactive and pragmatic sense - its modelling relation sense.
This how we get from semiosis of the actually modelled kind - the biosemiosis of life and mind - to recover some kind of semiosis as the pansemiosis by which the cosmos indeed brings itself into being.
One flaw in Peirce is he conflated the two - especially in his "transcendental" mid-phase of thought where he wrote his notorious comments about matter as effete mind, not making it clear enough whether this was pansemiotic metaphor or pansemiotic metaphysics.
It should be clear that I don't subscribe to the Cosmos as having its own model of itself in a biosemiotic encoded sense. And indeed, it is part of the very theory of biosemiosis that the very possibility of a symbolic code only gets born where physicalism reaches its own naturalistic limits.
A symbol has to be a physical mark, even if just a dot being printed, or a blank being left, on an infinite Turing tape. But the great trick of semiosis is that if you can afford to encode information in a way that seems physically costless, then you - as an organism - can escape all the strictures of the material world.
This is Pattee's epistemic cut. Life and mind arise because they can make physical marks - like a DNA codon or a new synaptic junction - which look perfectly meaningless to the physical world that they then sneakily turn out to regulate.
It costs the body as much to code for a nonsense protein as it does for some crucial enzyme. The world - as a realm of rate dependent dynamics - can't see anything different about the two molecules in terms of any material or structural physics. Both are equally lacking in meaning - and even lacking in terms of being counterfactually meaningless as well. The two molecules just don't fit any kind of signal~noise dichotomy of the kind that semiotics, as a science of meaning, would seek to apply.
But then the body does know the difference as the difference is precisely one it imposes on the physics. It says I could be producing molecular junk or molecular messages. You - the world - can't tell and so just have no say in the matter. I - the body - am thus absolutely free to throw proteins into the bubbling stew of metabolic action and see what sticks as the best evolutionary choice.
Evolution doesn't just happen to organisms. They invent the binary distinction of sense~nonsense so as to make themselves evolvable as something completely new - a structure of rate independent information - imposed on rate dependent dynamics of the merely physicalist world.
So yes, the human story has reached the point where it holds up a mirror to the physicalism of the real world. But it can only do that by adding itself as a further trick - the trick of semiotic mechanism - which the physical world does not appear to contain and which is only present because the physical world in fact has strict limits.
The physical world is capable of abolishing all entropic gradients. But it can't even see the negentropy that is the informal structure that an organism accumulates so as to have its own parasitic existence on this world.
It's a splendid irony. A form of transcendence in that a model of the world must transcend that world. And yet the books get balance as that brief escaped from entropy is then paid back to the world with interest. Life and mind earn their way in the cracks of existence by breaking down accidental barriers to maximum entropy - like the way industrialised humans are taking half a billion years worth of buried carbon, slowly concentrated into rich lodes of coal and petroleum, and burning the bulk of it in a 200 year party.
So the answer to your question is that there is further recursion in the physicalist tale as it now has to add the new thing that is life and mind. The mirror we hold up would show the Comos the self that is also now the one with us in it - the informational degrees of freedom that its laws of thermodynamics could never forbid, but which also didn't in any immediately obvious way seem to require.
It is only because entropification must be achieved in any way possible - and life and mind were the one further way possible - that we can be considered part of the natural order.
Is reality made of signs that are neither mental nor physical ? For this distinction is itself a cut of the sign ? — jas0n
This is the epistemic cut issue. As I previously said, the central trick of semiosis is that a sign is really - as Pattee makes clear - a switch. And it is then easy to see the connection as well as the cut. A mechanical switch is both a logical thing and a physical thing. It has a foot on both sides of the divide.
So that fact puts a halt to the homuncular regress. The two worlds - of entropy and information - are bridged semiotically at the scale of your smallest possible physical switches.
And that is what the biophysics of the past decade has confirmed. All life and mind is based on the ability of proteins - molecular structure - to ratchet the quasi-classical nanoscale of organic chemistry.
The nanoscale is the tipping point where all the key physical forces converge to have the same scale. It is the "edge of chaos" or zone of criticality. In material terms, it exhibits the maximum thermal instability.
And in being peak material instability - halfway between the quantum and the classical - it is also the most tippable state. Biological information can get in there and tilt the entropic odds in its own favour.
But all this is extremely new science. Even in biophysics, the fact is still sinking in.
Have you looked into Derrida's différance? — jas0n
Yep. But only doing due diligence.
:grin:
Generally post-modernism is the backlash against its own structuralist past. It wants to kill the part of itself that was valuable. It got tangled up in Romanticism, Plurality and Idealism in likewise wanting to distinguish itself from Enlightenment rationalism and the hierarchical views of Natural Philosophy.
As philosophy, it is a self-parodying mess. Yet of course, take any text in isolation and it often says something that could be seen as reasonable and obvious.
So between AP and Continentalism, I stick to Pragmatism as the middle path that offers the most coherence.
