TPF : Physicalism & Irreducibility
Posted: Sat Sep 02, 2023 10:41 am
The irreducibility of phenomenal experiences does not refute physicalism.

So the central argument against physicalism is the irreducibility of consciousness experiences to physical facts about our brains. ___Apustimelogist
The point I try to make is that if experiences are representations of things in the outside world then maybe they can never be reduced to brains. Yes, you can say - "well I have experiences and that is that" - but a physicalist could just say that his experiences are his brain. You would tell him he is wrong because experiences don't reduce to brains but if this irreducibility is something a physicalist expects or is consistent with physicalism then the argument wouldn't work. — Apustimelogist
I'm currently reading a book by Mathematician Charles Pinter, subtitled "How the Mind Creates the Features & Structure of All Things". And it's the creative aspect of the brain processing which produces mental experiences that are completely different from the physical source. I won't go into the details here, but basically the brain converts incoming isolated bits of information (e.g. photons) into integrated packets of meaning (e.g feelings, experiences, sensations) that are relevant only to the observer, and not inherent in the source.
Pinter uses the 20th century psychology Gestalt Theory of Perception to make his case. A Gestalt is simply a holistic collection of parts with a meaning that is not in the parts --- hence the experience or sensation cannot be reduced to the physical properties of the incoming photons or electrons that originated in an external object. In other words, the Representation (Map ; concept) is not the same as the Object (Terrain ; thing). The mental map excludes a lot of the physical properties, and artistically adds some interconnections & re-arrangements that are relevant only to the Perciever. The Whole is more than the sum of its parts.
The takeaway from this understanding of Perception as Interpretation, implies that the translated*1 subjective meaning (Qualia) cannot be reduced to the properties of the object (Quanta). Experiences are meaningful (significant) to the Subject, but meanings are metaphysical/immaterial, not physical/material. There's definitely a correlation between physics & metaphysics, but the creative causation (translation) by the brain produces novelty (a system), instead of merely reproducing the original. The brain is a machine for making meanings, but meaning is not the ding an sich.
*1. Translation often adds personal significance & feelings of the translator to the literal words of the author. The human brain is born with compartmentalized categories, which are later filled with personal experiences & feelings & prejudices. The image below is an example of the brain adding its own expectations to the incoming data. There is no triangle in the image.
THE TRIANGLE IS NOT OUT THERE, but added by the brain as a new meaning that is inferred, not seen
