We can only know of the world in-itself through logical limitations and consequences. Namely, some "thing" must be there. But beyond that, everything is a model we create that attempts to represent what is there. Knowledge is the the logical application of our representations for our best chance at matching to the consequences of its existence. But such an existence can only be known as the representations we hold, as we only know how the thing in-itself impacts the world, not what it truly is to exist as itself unobserved — Philosophim
No, definitely not. By analogy, for instance, the rules – generalizations abstracted from design (logical) space – for valid moves in chess (e.g. metaphysics) are not "over-arching means of determining" winning strategies for playing chess (e.g. physical theories).
Constrained in relation to what?
Also, experience of what?
Absolutely sense-data or sensations or however you want to call it, is fundamental to any metaphysics.
I think the minimum requirement of agreement should be, that metaphysics is about the world.
Someone who calls themselves a materialist or an idealist use evidence all the time, they'll say that, for example, the collapse of wave function counts as evidence for idealism, or they'll say that the progress of neuroscientific evidence proves materialism is correct.
So, you'd have to specify a bit, what you mean by not having an ounce of empirical data. As I see it, experience must count as empirical content, otherwise we are using the word "empirical" to mean, "publicly observable", these are not the same thing.
Sounds as if some kind of model-centric version would count as part of metaphysics for you. Because saying "model of possible experience" without specifying what this relates to, doesn't amount to much, so far as I can see.
I have nothing to define, but would you not agree that the OP's claim sounds like Metaphysical itself?
"X is unknowable." is also a Metaphysical comment.
Because if it were Science, they will make up some hypothesis on the object they want to find out.
For me, metaphysics it's the most important part of philosophy. My objection to your OP is that you attempt to discredit metaphysics using a definition that I, and most philosophers, don't believe is correct.
I've noted before I generally do not use philosophical terms such as 'metaphysics' in discussions, because as you can see from the many replies, no one can agree what they actually mean.
We can only know of the world in-itself through logical limitations and consequences. Namely, some "thing" must be there
If you recall the idea of "discrete experience", we part and parcel reality as we wish within our own minds. I can view a field of grass, a blade of grass, or a piece of grass. I do not even need to call it "grass". It is the applications of these identities in practice which determine their usefulness in representing how a thing in-itself impacts the world in a way that is not-contradicted by its existence.
Just wanted to chime in at how I thought this was a really great post!
On my end, I am using the definition used in the Kantian tradition, as well as Leibniz and many before him. — Bob Ross
If you have a different definition, then let’s hear it: I am more than happy to entertain other definitions. — Bob Ross
I'm not a Kant scholar, but I've read "Critique of Pure Reason." I don't remember it saying anything like "metaphysics is, in fact, indistinguishable from human imagination." I doubt that it did and I doubt that Kant thought it. I can't speak to Leibnitz, but I would be surprised if he felt that way. — T Clark
Constrained by our possible forms of experience: space and time. Just because I experience the outer world in space and time, it does not follow that they exist in the outer world itself; nor that anything I derive from my experience, which is conditioned by them, pertains to anything beyond it. Instead, it only holds valid insofar as it references a possible experience from a being which has a similar ‘type’ of experience as myself. — Bob Ross
I agree, if by ‘about the world’ you take it to mean that one is deriving what the world fundamentally is in-itself: knowledge of the absolute, the whole, the totality of existence, that which transcends you, ontology, etc. — Bob Ross
So, in other words, the ontological claims get stripped out, and what is left is the claim that we have reasons to consider the world that we experience as idealistic or physicalist (or what not) and not that the world in-itself actually is any of those. — Bob Ross
I guess I am not entirely following: the model relates to possible experience. Metaphysics, as the study of what which is beyond the possibility of experience, is ontological in nature. For me, a model is not an ontology: the former is a map for navigation, which may or may not be accurate to the territory, and the latter is a theory of what the territory is. — Bob Ross
No. Yes.Would you say, then, that metaphysics is informed by physics, and never vice-versa? — Bob Ross
Inferences from factual, or natural, axioms (i.e. physics) are sound. Inferences with "beyond" premises (e.g. magic, myths, ideals), whether or not they are valid, cannot be sound. Metaphysics is rational, at best, and itself is never theoretical (i.e. explanatory of nature). E.g. 'interpretations' of QM are metaphysical (re: ontology), not epistemological (i.e. predictive, or conclusive)³ – in Aristotlean terms they 'come after (i.e. categorical generalizations from, or (as per Collingwood) absolute presuppositions of)¹ the physics'. This is why Spinoza's scientia intuitiva¹ (holistic, nondual) follows from common ideas³ (objective) which in turn follow from inadequate, or imaginary, ideas² (subjective) – the latter two e.g. as per Peirce/Dewey. Of course, there are other 'interpretations of metaphysics' but I find them either less rational (i.e. unsound, anachronistic)² or irrational (i.e. invalid, faith-based / idealist / subjectivist aka "X-of-the-gaps").... for how could an abstraction from experience necessarily pertain to that which is beyond it?

First, concerning the sources of metaphysical cognition, it already lies in the concept of metaphysics that they cannot be empirical. The principlesb of such cognition (which include not only its fundamental propositionsc or basic principles, but also its fundamental concepts) must therefore never be taken from experience; for the cognition is supposed to be not physical but metaphysical, i.e., lying beyond experience. Therefore it will be based upon neither outer experience, which constitutes the source of physics proper, nor inner, which provides the foundation of empirical psychology
Space is not an empirical concept which has been derived from outer experiences. For in order that certain sensations be referred to something outside me (that is, to something in another region of space from that in which I find myself), and similarly in order that I may be able to represent them as outside and alongside one another, and accordingly as not only different but as in different places, the representation of space must already underlie them [dazu muß die Vorstellung des Raumes schon zum Grunde liegen]. Therefore, the representation of space cannot be obtained through experience from the relations of outer appearance; this outer experience is itself possible at all only through that representation...
...Space is a necessary a priori representation that underlies all outer intuitions. One can never forge a representation of the absence of space, though one can quite well think that no things are to be met within it. It must therefore be regarded as the condition of the possibility of appearances, and not as a determination dependent upon them, and it is an a priori representation that necessarily underlies outer appearances. — Kant
This is my fault, as I have been using the “world in-itself” terminology to refer to whatever exists beyond one’s experience, but I actually distinguish the “world in-itself” from “the absolute”: the former is actually a product of the model wherein organisms are thought to represent the world, and the latter is whatever exists completely sans anything we gain from our experience. — Bob Ross
The subtle difference, and contention I would have with your above quote, is that we cannot know, independently of evidence gathered from our experience (which is constrained by our possible forms of experience), that we represent objects in a space and time that transcends us: takeaway the forms of our experience (namely space and time that doesn’t transcend us) and it equally unintelligible that there is some “thing” out there. In other words, some “thing” being out there is a part of a model itself as well. — Bob Ross
To build off of this, I would say that our “discrete experience” of the objects, such as blades of grass, says nothing about what may exist in the world which transcends our possible forms: not even that there is a blade of grass—irregardless of what we label it. — Bob Ross
“Logical”, “model”, “representation”. I just want to point out that these concepts get their sense from to a particular sort of metaphysical foundation. If we shifted to a different metaphysics, — Joshs
Why only, "through logical limitations and consequences"? Could you elaborate?
I'd be more inclined to say, that we can only know the world through our nature, and the nature of other people, including the imaginitive thinking of our intellectual ancestors who managed to point the way towards having a more accurate view of nature, and... and... and...
Is that contradictory? — wonderer1
They can be useful words, but in philosophical conversation in which we are trying to come to an objective solution to a problem, these words have so much cultural subjectivity loaded into them that their meaning become debates within a debate… When having a discussion that needs clarity, we should remove such words where possible to focus on the true issue we wish to discuss.
— Philosophim
What about words like worldview, cultural subjectivity, formulation of problems, perspective, frame of reference, bias, set of presuppositions, paradigm? — Joshs
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
