I posted the following on another thread, and I think it contains the germ of something really important. But (as you will read) I handled/wrote it badly. I've never been able to edit myself (my long post in "Why I Am an Atheist" took me 4 hours to write, 3 months to edit).
But if I could gather a sort of working group of people with the skills in the thread title, I think we could come up with something that helps everybody understand how objective reality interracts with our subjective experience. I think that would be a useful exercise.
The thought that I was responding to was as follows:
"In the true sense that there's nothing like the experience of color anywhere in the universe except in a brain, so too, and ironically, God doesn't exist anywhere in the universe except in a human brain. The brain that believes "color" exists "out there" while arguing that God doesn't, is living in an illusion from which it's incapable of freeing itself."
So here's what I wrote:
"You are really missing something important, because you insist upon equating our subjective experience with reality, and at the same trying to prove that the two can't be reconciled. But I do not believe this to be so.
Consider a flower -- let's make it one that I perceive as purple. I'm going to make a lot of observations about this:
AND ALL OF THAT describes the actual reality. Not my subjective reality, nor yours, nor the bee's, nor the birds' and animals' that distribute seeds subjective realities either. But the one thing that it does admit of is this: that there is a flower, and there is a light spectrum that it reflects/absorbs -- and that is the reality. And, of course, that there are also you, me, the bees birds and animals, to perceive it -- each in our own way."
So, anybody want to volunteer to help me (us) make it better and more coherent?

Consider a flower -- let's make it one that I perceive as purple. I'm going to make a lot of observations about this:
- I say "I perceive as purple" because you have brought up the fact that this is only my own perception, and I have no idea what you perceive. Also you mention the colour-blind, who could not distinguish that purple from brown. But I put it to you, that for all those (the very large majority) who are not colour-blind, if you simply ask them (no prompting, now!) what colour is the flower, they will all respond "purple." So already we know something is happening.
- We know that bees (among other insects) perceive that flower quite differently, because they are seeing in a different section of the spectrum than we are. And we also know, if we adjust our cameras to "see" in that same spectral section, we can get an idea of what the bee sees -- and it really is quite different from what we see.
- We know that neither I, you nor the bee can see what we need to when there is insufficient light. Under moonlight or other dim light, for example, the bee doesn't see the flower's hints as to where the nectar is, nor can we identify the colour -- we see it just as the colour-blind individual does.
- We know that what we see -- and what the bee sees -- is a consequence of light being reflected and not reflected from that flower, and that it is that reflected light that we see. Everything reflects and absorbs different combinations of wavelengths, and that is what gives us the perceptions, subjective as they might be, that we have. Same for the bee.
- Both you, I and the bee, though we may have different goals with respect to this flower, are all able, using only the radiation that the flower reflects/absorbs, to obtain our individual objectives with respect to that flower. Me, to decorate my table, you to woo someone, the bee to collect nectar --------- and the flower! to get the bee to help it reproduce, and you and I and the birds and animals and winds to spread its seeds to where there will be an opportunity for its genes to live on and reproduce again!
AND ALL OF THAT describes the actual reality. Not my subjective reality, nor yours, nor the bee's, nor the birds' and animals' that distribute seeds subjective realities either. But the one thing that it does admit of is this: that there is a flower, and there is a light spectrum that it reflects/absorbs -- and that is the reality.
