Like today, there are people who deny the existence of qualia altogether, and think it’s an illusion or some such, so I imagine there will also be people in the future who claim that the material features you claim to give rise to qualia experiences, merely give rise to reports of qualia experiences.
I mean, there are still people claiming that Earth is flat, and that evolution is an absurd lie. But insofar as consensus on anything is ever reached, it basically always requires both detailed tangible evidence and abstract reasoning. I’m not denying that abstract reasoning is necessary, it’s just far less sufficient by itself than mainstream philosophy admits.
I still have to figure out what my values should be, right? Is your position that it’s entirely arbitrary, and any answer is as good as another (within the range)?
We do have meta-preferences about our preferences, and of course with regard to our meta-preferences our values aren’t arbitrary. But this just escalates the issue one level higher—when the whole values + meta-values structure is considered, there’s no objective criterion for determining the best one (found so far).
How do I know this is true? What feedback from reality can I use to decide between “questions without feedback from reality can only be answered arbitrarily” and “there’s another way to (very slowly) answer such questions, by doing what most philosophers do”
You can evaluate philosophical progress achieved so far, for one thing. I’m not saying that my assessment of it is inarguably correct (indeed, given that mainstream philosophy isn’t seriously discredited yet, reasonable people clearly can disagree), but if your conclusions are different, I’d like to know why.
I would categorize this as incorporating feedback from reality, so perhaps we don’t really disagree much.
