This is close to my view. But I think we need to be more radical, not less radical than this.
You write “Reality as disclosed to a knower has an ineliminably subjective or perspectival dimension.” So “as disclosed” actually reduces the claim, because indirect realism will already grant this much.
I suggest instead that reality itself “has an ineliminably subjective or perspectival dimension.” Reality is shared but not objective.
Experience is reality. Period. But of course we have a pragmatic use of “real” that applies to what we count on. The “appearance/reality” distinction is only pragmatic and relative.
Kant writes, as you quote:
that the things that we intuit are not in themselves what we intuit them to be, nor are their relations so constituted in themselves as they appear to us
The post-dualist approach to this is temporal rather than spatial. The object-for-me-here-now is only a “moment” of “aspect” of the object. The object is here for me here and now as also-for-others and in terms of its past and possibility. The case for this is phenomenological. We need only look at our non-theoretical life. I share the road with other drivers, trusting my life to sense of perceiving and acting on perceptual objects that are also there and pragmatically relevant to those other drivers. Or I get immersed in some playful conversation with my spouse. What we discuss is “there” as “there for both us.” And so on.
The things we depend on and care about are things as they ( partially) appear.
As I see it, we want to acknowledge the “transcendence” of objects. They are not “just for me” or “in my pineal gland.” We don’t need to put the empirical world “inside people’s minds” just because the empirical world is obviously perspectival.
I prefer my reading of Plato to Kant here. The “idea” of the thing is its unity. A thing is a temporal and intersubjective synthesis of its moments. The thing does not hide behind its moments, but it can only show one side of itself but not showing its other sides. So the thing “hides ‘behind’ itself” in this temporal rather than spatial sense. But this is relationship of being and time. The thing is fundamentally a temporal synthesis.
“On those stepping into rivers, other and other waters flow.”
The “pre-temporal” philosopher dreamed of collapsing reality into a single vision, a single moment. But the world is “music,” and music lives only in time or as time.
Right. The object is not “in my individual mind.” But the object may show a moment of itself to me that it shows to no one else. To me it’s better to just acknowledge that objects show themselves differently to different subjects. The object depends on no particular consciousness, but — in my view — consciousness in general is simply the being or the presence of the world. So a world “outside” of consciousness is basically nonsense, but this word “outside” is misleading, because consciousness is not “inside stuff” that “contains unreal images.” This is how I understand “nonduality.” I don’t have consciousness. Consciousness has me. I just accept the weird relationship of sentience and brains as a brute fact. This also means that I understand claims about “the” past by scientific models as Peirce does, which is to say as claims about the future. Scientific models are tools for meeting the future. Where is the year 1953 ? “It” exists in some sense. But how exactly ? This is a rich side issue, but it comes up in After Finitude.
I don’t know if I would use “naturalism” for this, but we agree that many philosophers just ignore the problem of perspective. That’s how I’d frame it. The empirical world is from-a-point-of-view. “Objective reality” is nonsense at worst and a vague target at best.
It’s not how you’d do it, but I attack this naivety from the “left.” The problem with “scientism” is that it is indulgently metaphysical and presumptuous, leaving its fundamental terms hanging in the air, undefined. What does one even mean by “exist” ?
Scientism loses the empirical object of actual science, because scientism ( as I intend it here ) is just as metaphysical as a sophisticated theism ---- is a curious variant of theism, but its “God” has withered into mystified mathemagical truthmaker.
Instead of qualitative empirical objects, we get a bifurcation of “inside qualia” and the tiniest residue of “external true object.” This is utterly divorced from how we live and what we care about. It replaces reality with a video game.
