I don't specifically recall the "distinction" you cite. — Pop
I wasn't getting at anything, although I do think we're getting semantic information mixed up with the kind of information scientists use, including biologists. Do you think? — frank
There are two papers in the link titled "What is information". The focus is DNA and information, but it is still relevant to general consideration. — Pop
Maxwell's demon
— frank
We are talking about open systems. Natural systems are dissipative. I'm not sure what you are getting at? — Pop
Just so we're clear that copying DNA is not a case of semantic information. No cognition involved. — frank
Good lord. Maxwell’s demon is how classical mechanics introduces the epistemic cut that underpins thermodynamics and hence dissipative structure theory.

And that led to Feynman’s ratchet to show the quantum limit of any such informational demon. — apokrisis
This is the code paradigm, the idea that ‘life is chemistry plus information plus codes’. - — Pop
What is not clear...is the ontological status of information, and the result is that today we have two conflicting paradigms in biology.
One is the ‘chemical paradigm’, the idea that ‘life is chemistry’, or, more precisely, that ‘life is an extremely complex form of chemistry’.
The other is the ‘information paradigm’, the view that chemistry is not enough, that ‘life is chemistry plus information’.
This implies that there is an ontological difference between information and chemistry, a difference which is often expressed by saying that information-based processes like heredity and natural selection simply do not exist in the world of chemistry.
Against this conclusion, the supporters of the chemical paradigm have argued that the concept of information is only a linguistic metaphor, a word that summarizes the result of countless underlying chemical reactions. [This is exactly the contention of reductionist physicalism - wayfarer]
The supporters of the information paradigm insist that information is a real and fundamental component of the living world, but have not been able to prove this point. As a result, the chemical view has not been abandoned and the two paradigms both coexist today.
Here [e.g. in this paper - wayfarer] it is shown that a solution to the ontological problem of information does exist. It comes from the idea that life is artefact-making, that genes and proteins are molecular artefacts manufactured by molecular machines and that artefacts necessarily require sequences and coding rules in addition to the quantities of physics and chemistry. More precisely, it is shown that the production of artefacts requires new observables that are referred to as nominable entities because they can be described only by naming their components in their natural order. From an ontological point of view, in conclusion, information is a nominable entity, a fundamental but not-computable observable. — Marcello Barbieri
Ok, but DNA replication still isn't semantic information. Should we discuss the difference? — frank
Information is a property. — frank
Information is a property. — frank
What Barbieri is showing, is the sense in which the storing and transmission of information differentiates life from non-life. — Wayfarer
We have been through this before - How is it relevant for irreversible systems? — Pop
So, what is crucial here, is that Barbieri is claiming there's an ontological distinction between living organisms and non-organic matter. That is what is resisted by 'the chemical paradigm', because if it's true, then materialism proper - the contention that matter-energy is all that exists - can't be maintained. — Wayfarer
We are discussing Barberi's paper. Did you read it? — Pop
Since the early 1970s, Italian embryologist and theoretical biologist Marcello Barbieri has been developing a biosemiotic framework for biology based on his analysis of the cell’s internal organic codes. Developing his theory of semantic biology in complete independence from the Sebeokian biosemioticians, but now widely recognized as a key figure in the development of 21st century biosemiotics, Barbieri proposes an alternative biosemiotic paradigm that is not organicist and qualitative in its origins, but mechanist and molecular instead – but that is just revolutionary a framework for the attempt to scientifically investigate and understand the reality of sign processes in life processes
There are 21 papers we are focusing on, and the broad thrust is a reconsideration of what is meant by "information" at the cellular level.
**These papers an excellent source for getting a feel for the cutting edge in contemporary understanding. — Pop
I have always had trouble with the term semiosis as it implies an interpreter. But why should meaning have an interpreter? — Pop
A semiotic relation exists when some sort of habit of interpretance reads the world in terms of its “signs” and responds with the certainty of automatic reflex. — apokrisis
In the early universe there could not have been an interpreter, but form arose and developed.
In one sense everything is a development of form. — Pop
Just some thinking that badly needs integration. :sad: — Pop
What you do not understand is - when you look at a rock it changes your brain patterning. So what exactly changed your brain patterning? — Pop
Meaning may be meaningful in its own right. — Pop
As Pattee put it, the central problem for biology is to explain how a molecule can be a message (and not just a material). — apokrisis
One can lead the horse to integration, but one can’t make it integrate. — apokrisis
