@Pharoah said: "I would suggest not mentioning phenomenal qualities in your overall explanation/description of the evolution of life" - fair comment and I have considered it. I can't say what the physiological processes in intimate detail because I am not God.
@Soupie: If phenomenal qualities arise or are generated by physiological processes, biologists/neurologists will--as technology allows--be able to describe them in intimate detail. Omniscience would not be required.
Pharoah said: Technically, THz reflection is a conceptual representation and still lies on the subjective side although we rightly feel pretty confident (being realists) that there is objective truth in this.
Soupie: I disagree. THz, or terahertz, refers to the oscillation/movement of electromagentic waves through space. The movement of electromagnetic waves is objective.
Pharoah said: [T]his is not the case: "What can be represented physiologically are particle/wave frequencies." …
The phenomenal experience of colour is a different kind of non-conceptual representation. I have reached some agreement I think with you @Soupie ..., that physiological mechanisms do represent colour in a qualitatively relevant way.
Soupie: Pharoah, let’s clarify what you are saying. We have three (3) variables here:
- A physical stimulus (electromagnetic wave) = X
- A physiological mechanism (chemical reaction) = X1
- A phenomenal experience (blue) = X2
You appear to be making two claims:
- If X is good for organism, then organism will evolve X1 that represents X.
- X1 will represent X2.
The problem with claim I. is that it doesn’t tell us anything about X2. It doesn’t tell us what color is, where it comes from, or why it exists (what’s its function).
The problem with claim II. is that, again, you haven’t explained what X2 is, where it came from, or why it exists.
A physiological mechanism might represent a physical stimulus. But it does not follow that a physiological mechanism will represent a phenomenal quality.
Where does this phenomenal quality exist that there may be a physiological mechanism that might represent it?
Does blue exist out in space? You’ve said no, phenomenal qualities are observer dependant and that they exist in the body/brain.
Perhaps what you mean to say is:
If X is good for the organism, then organism will evolve X1, and from X1 will emerge X2.
That is, if electromagnetic wave X is good for the organism, then organism will evolve representational physiological mechanism X1, and from physiological mechanism X1 will emerge the phenomenal quality blue X2.
The problem with the above scenario is that it does not tell us what blue is, where it came from, nor why it exists.
Pharoah: I do think I have explained why fairly well in the paper... not well enough no doubt.
… why? yes I have.
Where?... the brain and body…
what? What?!
Soupie: I’m sorry, I don’t see why on your description phenomenal qualities exist. It seems that physiological mechanics carry the load.
It’s clear that you believe physiological mechanisms and phenomenal qualities are intimately related. I don’t disagree. However, you have not explained how nor why they are related.
What are colors? Are they physical, phenomenal, or something else?
Pharoah: I have explained what colors are... from a realist stance they are worldly characteristics that have observer-dependent qualitative relevancies (thanks to the evolution of lifeforms)...
Soupie: You say colors are “worldy” characteristics. Are colors physical or phenomenal characteristics?
As to what your theory has to offer-- as
@smcder noted some time ago--I don't see what it offers beyond the standard theory of evolution via natural selection. And so far as I can tell, it doesn't
explain the origin, evolution, or function of consciousness.
