But if you take away or change the object then that value disappears or changes. So the phenomenon of value is not not 100% subjective.
The same could be said for a pink triangle. If you look at it, you see it; when the physical pink triangle goes away, you stop seeing it and start seeing something else. But consider this--a person who is blind can look at it without seeing it, and a person who is synesthetic can see it without looking at it (I chose pink triangle specifically because my girlfriend has synesthesia, and once reacted to the sound of a chain going over a winch with "SO MANY TRIANGLES!!!!!!" The were pink. It was funny. She has also ordered me to change my ring tone because the sound of it causes her to see an offensive shade of bubble-gum barbie pink.)
However, take the person out of the equation, and an interesting thing happens. You can paint a pink triangle and leave it in the woods--you can even leave a loop of chain hanging over a water-wheel, for good measure. In that situation, there will *definitely* be no pink triangles, because there are no eyes and brains around to interpret the physical reality of light waves into the experience of pinkness or triangularity.
The sight of the pink triangle
seems to rely on the existence of a "real" one, but unusual situations reveal the truth about it--the sight itself is a 100% psychological experience. It's one which
often happens to be triggered by and associated with certain situations in physical reality but the connection is incidental. The physical reality it is associated with, and the experience of it, can be completely separated. The experience itself happens only in the brain and nowhere else.
Which means something very significant. If you take away the object, there
may or may not be a change in the experience (I'll clarify that in a bit), but take away the person, and there will
definitely be no experience at all.
I accept that value is in the brain, but that value often emerges on interaction between the object and the brain. I recall that science teaches us that listening to music can cause the release of endorphins, which is why certain music sounds good to us. We don't have to think about this, it is something that we experience. The music is good. Such value necessarily depends - as far as we can tell - on unconscious processing of the stimulus, I fully accept that. But the phenomenological experience we consciously encounter actually has value in it.
Rather than being a monotone field of {0, 0, 0, 0, 0...} which we have to ruminate on to change the value of, I turn on Beethoven and are confronted with {+3, +4, +5, +2, +1, +5, +6...}. Or noisy roadworks start and I find myself in the middle of {-2, -4, -5, -6, -2...} if you understand the idea. To borrow an idea from science, value is part of the "field equations" of phenomenological reality. Such things can be difficult to change.
This may or may not be relevant, but I want want to understand what you mean. As I understand, the numbers here are attempts to codify enjoyment? 0 is nothing interesting, negative numbers are unpleasantness and positive numbers are enjoyment, magnitude describes the degree of enjoyment (or distress) caused by the experience?
No, value does not usually depend on wish as far as I can recall, at least in the sense that we can change a value on whim. That's why I am willing to pay for Beethoven to replace silence, or theatre tickets to replace watching drying paint, and paint to cover up the ugly marks on the wall. I cannot just wish the silence, or the road works into having the aestethic value of Beethoven etc, no matter how hard try.
Many people (mostly monks) have trained their minds to find satisfaction in utter silence and stillness. To find the world in nothing.
Even if you are not inclined to do that, you can still close your eyes and imagine Beethoven, or--to move farther from the outside world--music of your own creation. You can cause yourself to have the psychological experience, absent the physical stimulus.
Which comes back to what I was saying before:
The physical reality, minus the person, is nothing at all. No value, no enjoyment or distress, nothing.
The person, minus the physical reality, can still experience the value of that thing.
So the value relies entirely on the person, and only minimally, if at all, on the thing.
