From
here.
Again, thanks for your comments on the OP. Here I would like to clarify the key points where my claim goes further than a cautiously realist reading would allow.
The main divergence lies in what we
take for granted about the independence of the world “as it is”—that is, the world assumed to exist apart from all modes of disclosure, experience, or intelligibility. While nobody would disagree that the mind plays a role in cognition—supplying the conceptual framework, perceptual integration, and interpretive acts by which we know—they would nevertheless retain an innate conviction that there exists, in the background, a world that is
fully real and determinate independently of mind. This is what I see as the import of
metaphysical realism and that is what I am seeking to challenge.
My position is closer to what might be called a phenomenological form of idealism: it asserts that there is no reality outside of
some perspective, not in a merely epistemological sense (i.e., that we only know from a point of view), but in a deeper sense—namely, that the very structure of the world, as intelligible and coherent, is
constituted in and through the relation to mind. Not an
individual mind, of course, but the noetic act—the perceiving, structuring, and meaning-bestowing – that makes any world appear in the first place. (Relevant to note that the etymology of 'world' is from the old Dutch 'werold' meaning 'time of man'.)
To make this clearer, consider the example you cite of Neptune’s pre-discovery existence. The realist insists: “It existed all along—we simply didn’t know it.” But the claim I'm advancing would point out that what “it” was prior to its discovery is not just unknown, but indeterminate. The very notion of “an object that exists but is wholly outside any possible disclosure” is, I suggest, an imaginative construction. It is an extrapolation or projection. The fact that it might be accurate doesn't undercut that.
I'm not arguing for solipsism or Berkeley's idealism. I’m not saying “nothing exists unless I think it.” Rather, I’m arguing that the world as a coherent totality is incomprehensible outside the structures of consciousness. It’s not that the mind projects onto a blank slate, nor that it merely filters a pre-existing reality, but rather that reality as it shows up at all is a
co-arising: dependent on the mutual implication of mind and world. (This is the aspect that is specifically phenomenological.)
This is why, when I write that “what we know of its existence is bound by and to the mind,” I do not mean this as a mere limitation of our faculties, but as a disclosure of something fundamental: that intelligibility is not something we add to a blank canvas but something that arises with, and through, the encounter of mind-and-world.
The critique that “the world exists anyway” misses this crucial nuance. Of course, something is there. But to designate it as “the world,” or even as “something,” already presupposes the categories of thought—form, object, existence, and so on. The realist mistake, in my view, is to treat these categories as transparent labels for things that are "there anyway", failing to recognise the way the mind categorises and situates them, without which they would be unintelligible.
Regarding “form”: Aristotle posits forms as intrinsic to particulars, but in a way that already implies a kind of noetic participation—form is what renders a thing intelligible, it is how we know what it *is*. I agree with that, but add a post-Kantian refinement: the intelligible world is not merely a cross-section or partial view of some greater reality—it is the only world we encounter. To speak of things as intelligible independently of any mind is, I believe, to risk incoherence. Intelligibility is not something that can be separated off from consciousness and remain intact. As our empirical knowledge of the universe expands, it becomes incorporated into the intelligible body of knowledge that consitutes science.
So in sum: my position is not that mind is just one actor among others in an otherwise mind-independent world. It is that there is no world at all without mind—not as a subjective opinion, but as the condition for appearance, for disclosure, and for anything we might meaningfully call real.
And finally, the reason this matters is so we do not lose sight of the subject—the observer—for whom all of this is meaningful in the first place. The scientific, objective view is essentially from the outside: in that picture, we appear as one species among countless others, clinging to a pale blue dot, infinitesimal against the vast panorama that scientific cosmology has revealed. But it is to us that this panorama is real and meaningful. So far as we know, we are the only beings capable of grasping the astounding vistas disclosed by science. Let’s not forget our role in that.
