The experience of an object is in the brain, but it depends on an object (in sensory experience at least) called the "distal stimulus". Otherwise we may have an illusory experience (e.g. a hallucination) but it is not an experience of an real object.
And yet, from the point of view of the experiencer, it may be exactly the same as if it
was an experience of a real object. That's my point, exactly--that experience is only incidentally and partially connected to reality, and any value attributed to the experience is even more distantly removed.
I know that experience of value can change from person to person, and from one time to the next. But you make it seem like "it's all in the head and dependent on wsh or whim" which is not true.
"Wish" might have been the wrong word, as people rarely
choose their tastes, priorities or values. I was trying to convey the personal nature of value, but it is true that personal things aren't necessarily chosen.
Not an identical one. But besides you miss the point. Take the prospect of eating dog poo. We have "gut feelings" about it, it's not just a matter osf expressing arbitrary judgement. The same with life, but hopefully it will not be so repulsive.
Dog doo is a physical substance, containing the wastes of dogs, including various microorganisms we've labeled bacteria. Over the last zillion years--give or take-- people who tended to avoid it were less likely to die of diseases caught from it than the people who picked it up and played with it. From that, people have developed a gut reaction of disgust in response to the experience of dog doo (I am disgusted by images of it, even if they aren't real, and by thoughts I might have of it, even if they've never happened, and I would probably be disgusted by hallucinations of it, even if I knew they weren't real).
My feeling of disgust is not caused by the poop. It's caused by the zillion years of evolution that carefully selected for disgust at the idea of poop. The only role that the poop had was in the past--it caused people who didn't have that trait to not become ancestors.
Except the realit itself, assuming idealism is false.
The reality would be very, very different than the experience, though. The reality of a Picasso in the woods is not a Picasso in the woods. The reality is a collection of fine minerals on pulverized wood or animal skin, reflecting different wavelengths of light. What is the value of a wavelength of light?
Ok look at a spanner. You need to tighten a bolt. I hand you a screwdriver and say "the value of the object is in the person, so you can make a screwdriver as valuable as a spanner by training your mind."
You're talking about usefulness, which I think is very different, being much closer to physical reality. I might value that screwdriver very highly--maybe my grandpa gave it to me before he died. Maybe I am sexually oriented toward objects, and I'm married to the screwdriver. That doesn't make it the right tool for the job.
