Some of this can be supported by research, and probably some of it can't yet, but it's the overall story I lean toward these days. The inferences that we think of as 'belief formation' aren't really much like any sort of formal logic, so there's no such process that would be isomorphic to some logical structure of nature.
Even single-cell organisms can display behavior we might as well call 'rational' in avoiding danger and seeking nutrients. But they don't deal in reasons and persuasion and counter-arguments and counter-examples and all that stuff that logic is useful for.
Actually, it's not making the mistake, so much as pointing out the mistake. I think the same can be said with the other passages I mentioned (although of course to really verify that would mean going back and looking at them in context.) I agree with every word in your cited text, but then it does capture the critical Kantian point. (I also note how thoroughly the phrase 'the view from nowhere' has become part of the lexicon, thanks to Thomas Nagel, I think.)
So when you say 'there is no reason to think that objectivity is actually equivalent with truth', then you're articulating the critical attitude, not the attitude of those for whom there is no criterion of truth other than objectivity - that being the naive realist!
Suppose we call knowledge the notion, and the essence or truth “being” or the object, then the examination consists in seeing whether the notion corresponds with the object. But if we call the inner nature of the object, or what it is in itself, the notion, and, on the other side, understand by object the notion qua object, i.e. the way the notion is for an other, then the examination consists in our seeing whether the object corresponds to its own notion. It is clear, of course, that both of these processes are the same. The essential fact, however, to be borne in mind throughout the whole inquiry is that both these moments, notion and object, “being for another” and “being in itself”, themselves fall within that knowledge which we are examining...
But not only in this respect, that notion and object, the criterion and what is to be tested, are ready to hand in consciousness itself, is any addition of ours superfluous, but we are also spared the trouble of comparing these two and of making an examination in the strict sense of the term; so that in this respect, too, since consciousness tests and examines itself, all we are left to do is simply and solely to look on. For consciousness is, on the one hand, consciousness of the object, on the other, consciousness of itself; consciousness of what to it is true, and consciousness of its knowledge of that truth. Since both are for the same consciousness, it is itself their comparison; it is the same consciousness that decides and knows whether its knowledge of the object corresponds with this object or not. The object, it is true, appears only to be in such wise for consciousness as consciousness knows it. Consciousness does not seem able to get, so to say, behind it as it is, not for consciousness, but in itself, and consequently seems also unable to test knowledge by it. But just because consciousness has, in general, knowledge of an object, there is already present the distinction that the inherent nature, what the object is in itself, is one thing to consciousness, while knowledge, or the being of the object for consciousness, is another moment. Upon this distinction, which is present as a fact, the examination turns. Should both, when thus compared, not correspond, consciousness seems bound to alter its knowledge, in order to make it fit the object. But in the alteration of the knowledge, the object itself also, in point of fact, is altered; for the knowledge which existed was essentially a knowledge of the object; with change in the knowledge, the object also becomes different, since it belonged essentially to this knowledge.
If you say in the latter statement that there can be many formalisms mapping on the same rules, then formalism is distinct from rules. And surely, by formalism, you could mean to refer to the logic rules as you also stated. But were this the case the following claim of yours “1. Logic is a set of formal systems; it is defined by the formalism” would equate to “1. Logic is a set of logic rules; it is defined by the logic rules” which sounds, if not tautological yet, very little informative.
To me it’s more clear to simply say that formalism is the symbolic codification of logic rules as opposed to the natural language codification of such rules.
Independently from the merits of Tarski’s semantic theory of truth for formal systems, if the price for it is to relativize the notion of truth to a given (object) language, my problem with it is: what does “if and only if” in the T-condition mean? If the be-conditional requires the notion of “True” to be understood as a logic operator, but the notion of true can not be applied at the same language level in which the bi-conditional is expressed, then what does that bi-conditional even mean? Besides asserting p (in the most basic object language and since it’s a language it can offer just representations of facts not facts themselves) doesn’t mean that p is true.
All I can say at this point is that if your naturalist assumptions play a role in your understanding of logic, then they deserve to be addressed as well.
What you may be tempted to say instead is that if there are representational tools that can successfully represent the world, then the world must be such that our representational tools can succeed in representing it. But this claim does very much sound like claiming that we can represent the world that we can represent, doesn’t it?
Logic rules allow us to infer some conclusions from some premises. Such rules ensure that if the premises are true, then the conclusion is true. And that’s possible because from premises to conclusions we are manipulating our own representations so that, semantically speaking, there is no more truth in the conclusion than there is in the premises, there is no more information in the conclusion than there is in the premises. The mapping to the world can be done by the premises. But logic would work even without any such mapping. E.g. Premise 1: squares are triangles; Premise 2: triangles are circles; Conclusion: squares are circles.
It’s not the world that satisfies such rules, but our representations of the world. While we can represent and logically process representations of state of affairs that do not map into reality and do not correspond to facts, are there real states of affairs that we can not represent ? But how can we answer such question without possibly representing such state of affairs? What are we picking with the notion “state of affairs“ for whatever goes beyond our means of representation (so including the notion of "state of affairs" itself)?
I have real trouble accepting this, but then, it is Wittgenstein, so who am I to question it?
I myself have often appealed to the ‘illusion that the so-called laws of nature are explanations of natural phenomena’ in arguing against scientific realism but this response taken as a whole seems unreasonably sceptical to me.
It seems to me that Wittgenstein’s argument is similar to Hume’s in denying the necessity of inductive logic. I suppose it’s something to do with the fact that causality - a causing b - is neither deductively true nor directly observable. But isn’t this where ‘Kant’s answer to Hume’ is supposed to apply i.e. causality as being a necessary condition of reason?
I think where it seems wrong to me is that it presumes that because causation only pertains to the phenomenal sphere, then it says nothing about ‘the world in itself or its meaning’. I think that’s an unreasonable inference. But I’m interested in what others have to say about it.
Does this not contradict Heisenberg Uncertainty and it's approach to measuring the quantum cloud of possible locations of elementary particles?
If we conceive of conceptual structuring as a universal feature of the mind, then there is no threat to objectivity, because questions of objectivity simply cannot arise. Sense organs and the brain do not just register the world. Our minds structure our experience and our thought in fundamental ways. To think that this in itself could compromise objectivity is to imagine that we could think without brains, see without eyes. To the extent to which this is Kant’s point about our perceiving the world only as phenomenal (as it is structured by our minds) and not as it is in itself (as it is in its unstructured form), then this is just to say that we cannot think without minds any more than we can see without eyes. Unmediated perception (and thought) is not objective perception: it is not perception at all...
So that we are not misled into simply associating objectivity and truth, it is worth highlighting one very important difference between them. Whereas truth is absolute and does not come in degrees, objectivity only comes in degrees. The idea of absolute objectivity is a misconception, encouraged by thinking of it as a view from nowhere. If there is no view from nowhere, there is no limiting case where, having progressively become more and more objective, a theory can finally attain absolute objectivity. Objectivity does not become like truth in the limiting case. Indeed, some of the deepest and most persistent problems for understanding objectivity arise when one tries to make it absolute, or at least inadvertently thinks of it in absolutist terms.
What we are seeking to do in imposing standards of objectivity in our judgements in modern science is to identify and separate the informative and the uninformative, with a view to producing reliable results. Objectivity is more mundane than ‘the search for truth’, and it is in its very mundaneness, by contrast with the ‘search for truth’, that its value lies.
Objectivity - A Very Brief Introduction
It is metaphorical in the sense that it anthropomorphizes the process of natural selection as if it were an agent following rules of logic, and the case of computers is similar.
It may be worth noting that the causative rules we use for computation are not the same as logic
but (for example) philosophers seem convinced that material implication is at best a poor approximation of actual implication, and yet computers "make due" with material implication. Of course there has also been an interesting reciprocal causality between computers and the field of logic, such that it is more difficult to separate the two now than it was in the past.
I posted a thread on stackexchange about the relationship of logic and causation. It turns out they’re different topics. Logic is the relationship between propositions whereas physical causation involves many factors. You can find the discussion here. The very first response notes that the ‘because’ of logical necessity is not the same as the ‘because’ of causation. And a lot hangs on this distinction, it turns out.
Another point is, apropos of the other thread on Schopenhauer - his ‘fourfold root of sufficient reason’ also differentiates between the logic of being knowing (which approximates to what we are calling logic) and the logic of becoming (which approximates to physical causation.)
I personally am very drawn to your (3) - that there is a logic in order of things, as the Greek intuition has it. I think the issue with that is that it seems to contravene the naturalist assumption of there being no telos. But also notice that related to this concern, the whole concept of ‘natural law’ is nowadays called into question. See for example There are no laws of Physics. I *think* this mirrors a confusion, but I’ll leave it there for now.
I think you didn't clarify much what you mean by "formalism". As a starter, I take "formalism" to be broadly speaking the symbolic codification of a set of logic rules. If there are one or many sets of logic rules, this is a distinct issue.
"Formalism" to me is required to standardize a given set of rules and remove ambiguities of ordinary language for certain syntactic terms (e.g. we can attributing different meanings to “to be“, “if…,then…”, “not”, “or” or “all” in logic).
Said that, I find the expression "one true logic" nonsensical. One may be willing to count "logic" by counting the number of "set of ‘logic’ rules" we want to distinguish (for example in geometry different set of postulates can different geometries the same can go for logic see e.g. non-classical logic). But there is no way for me to make sense of “true” as applied to “logic” since the notion of “truth” is built in the “logic” rules themselves, in other words the meaning of “truth” is determined by “logic rules” too. One might be tempted to see “logic rules” as a description of how things are, but that’s a categoric confusion to me: “logic rules“ are rules, not description of facts. To me.
Broadly speaking yes, if you mean by "logic of cause" the set of semantic rules that govern the notion of “cause”. However, more strictly speaking, "logic" refers to rules governing synthatic terms (like propositional operators, quantifiers, modal operators, etc.)
Formalism helps us discriminate better different ways allowing us to meaningfully speak of things according to various sets of “logic” rules.
What does one mean by “being sufficiently rational”? To me, appeal to “rationality” is nothing other than an appeal to the set of rules thatmust be satisfied in order to make things intelligible to somebody. And this may certainly include logic rules, too.
3. Logic refers to rules that make the world intelligible to us.
Believe it or not neighbors can deliberate with one another without the need of any state authority and men can design and build infrastructure without being a state employee. In fact, the state more often than not contracts out these duties to private entities.
As for collective action, there is nothing collective about state activity. I’ve never once been consulted about roads or bandits. Have you? These sorts of decisions are never collective, but are invariably decided by a cabal of politicians, officials, and their bagmen.
And no wonder people cannot band together to fix a simple road; they have been taught their whole lives that people cannot, nor should not do so. No wonder people cannot band together to help the poor in their community, or fix potholes, because they’ve been taught their whole lives that they do not need to bother, that we can let some politicians and officials take our money and they will handle it for us.
I do not believe that any significant proportion of human beings will turn into bandits and murderers as soon as they find themselves free to do so. I’ve met enough people to conclude otherwise
The absurd presumption is that we are obliged to choose between two defunct cannons.
Not only eminent domain, but civil forfeiture, taxation, tariffs, subsidies, minimum wages, welfare, regulation, and so on. Wherever the state takes from some persons what belongs to them and gives it to other persons to whom it does not belong, there you have plunder, and that is the nature of the business of your lord.
That a law like the 5th amendment and courts make the process of theft more difficult for the state, none of that, nor your authority on project management, negate the intents and efforts to take what isn't theirs and give to whom it does not belong. The courts are still beholden to the same laws as devised by the state, and eminent domain or some version thereof is present in every liberal democracy. In Canada it is "expropriation". In Australia it is "compulsory acquisition". These words do not mean nothing.
I would also say that the claim that there is private ownership is a myth, used as it is to disguise the reality that we have hardly left the state of serfdom. To purchase some means of production, like land for instance, one cannot just go out and stake an area for private use and claim jurisdiction. It's only "private" if the state allows it to be, which isn't saying much because they can come and take it any time they want.
And we really have to remember that the most successful version of socialism has been with social-democracy, which is still quite alive an kicking in the Western World. Social Democrats have ruled many Western countries and are and inherent part of Western democracy just as are conservatives.
Even Christianity has had this with it's Crusades, which really is a bizarre feat to pull out from the teachings of Jesus Christ, and all those time people wanted to build "The New Jerusalem".
The argument that seems salient to ↪vanzhandz's OP is that if one can say nothing about the mooted "base reality", then it is irrelevant to our conversations.
Alternately, if we do talk about this "base reality", then it's not the case that we can say nothing about it.
↪schopenhauer1 Other minds have always been a problem for idealists.
Trouble is, it’s so unclear what idealism is.
But yes, idealism has difficulty in avoiding solipsism, as I’ve explained previously. It usually needs God’s help.
Idealism has been moribund since the end of the century before last, and of little more than historical interest. That it is so popular in this forum is a peculiarity of the forum.
One essential criticism about Descartes’ “I think, therefore I am” is that we have no idea about what “to be” or “to exist” means. The same applies to our conversation as a proof that the world exists, which is almost the same argumentation adopted by Descartes: it cannot be proof of the existence on the world, because we have no idea of what “existence” means.
I think you have it backwards. We don’t understand language through experience de, we understand experience through language.
It is sometimes said that animals do not talk because they lack the mental capacity. And this means: "they do not think, and that is why they do not talk." But—they simply do not talk. Or to put it better: they do not use language—if we except the most primitive forms of language.—Commanding, questioning, recounting, chatting, are as much a part of our natural history as walking, eating, drinking, playing.
Thinkers in physics (Karen Barad), biology(Stuart Kauffman, Lynn Margolis), the social sciences and philosophy extend Witt’s work on human discourse to the non-human world in order to show that reciprocal interaction within a field or configuration applies not just to human discourse but to the biological and physical worlds in themselves.
Precisely which causal architecture for integrating information is the smell of pine? No answer has been offered and none ever will: these proposals set themselves an impossible task by assuming that objects in spacetime exist when not observed and have causal powers. This assumption works admirably within the interface. It utterly fails to transcend the interface: it cannot explain how conscious experiences might arise from physical systems such as embodied brains.
Suppose that I am an agent—a conscious agent—who perceives, decides, and acts. Suppose that my experiences of objects in spacetime are just an interface that guides my actions in an objective world—a world that does not consist of objects in spacetime. Then the question becomes: What is that world? What shall we place in that box labeled WORLD?
Let’s grant, provisionally, that we have conscious experiences, that we are fallible and inconsistent in our beliefs about them, and that their nature and properties are legitimate subjects of scientific study. Let’s also grant that our experiences, some of which we are consciously aware of and many of which we are not, inform our decisions and actions; again, taking these as ideas to be refined and revised by scientific study. Let us grant, in short, that we are conscious agents that perceive, decide, and act.
Then the question remains: What is the objective world?
Could conscious experiences bubble out of a computer simulation? Some scientists and philosophers think so, but no scientific theory can explain how. Simulations run afoul of the hard problem of consciousness: if we assume that the world is a simulation, then the genesis of conscious experiences remains a mystery.
--
We can convey an experience by a mere expression. This is data compression of impressive proportions. How much information is wrapped up in an experience, say, of love? It’s hard to say. Our species has explored love through countless songs and poems and, apparently, failed to fathom its depths: each new generation feels compelled to explore further, to forge ahead with new lyrics and tunes. And yet, despite its unplumbed complexity, love is conveyed with a glance. This economy of expression is possible because my universe of experience, and my perceptual interface, overlaps yours.
There are, of course, differences. The visual experiences of the colorblind differ from the rich world of colors that most of us relish. The emotional experiences of a sociopath differ from ours in a way perhaps inconceivable to us, even in our darkest moments. But often the overlap is substantial, and grants us genuine, if but partial, access to the conscious world of another person, a world that would otherwise lie hidden—behind an icon of their body in our interface.
When we shift our gaze from humans to a bonobo or a chimpanzee, we find that the icon of each tells us far less about the conscious world that hides behind it. We share with these primates 99 percent of our DNA, but far less, it would seem, of our conscious worlds. It took the brilliance and persistence of Jane Goodall to look beyond the icon of a chimp and glimpse inside its conscious world. 15
But as we shift our gaze again, from a chimp to a cat, then to a mouse, an ant, a bacterium, virus, rock, molecule, atom, and quark, each successive icon that appears in our interface tells us less and less about the efflorescence of consciousness behind the icon—again, “behind” in the same sense that a file lies “behind” its desktop icon. With an ant, our icon reveals so little that even Goodall could not, we suspect, probe its conscious world. With a bacterium, the poverty of our icon makes us suspect that there is, in fact, no such conscious world. With rocks, molecules, atoms, and quarks, our suspicion turns to near certainty. It is no wonder that we find physicalism, with its roots in an unconscious ground, so plausible.
We have been taken in. We have mistaken the limits of our interface for an insight into reality. We have finite capacities of perception and memory. But we are embedded in an infinite network of conscious agents whose complexity exceeds our finite capacities. So our interface must ignore all but a sliver of this complexity. For that sliver, it must deploy its capacities judiciously—more detail here, less there, next to nothing elsewhere. Hence our decline of insight as we shift our gaze from human to ant to quark. Our decline of insight should not be mistaken for an insight into decline—a progressive poverty inherent in objective reality. The decline is in our interface, in our perceptions. But we externalize it; we pin it on reality. Then we erect, from this erroneous reification, an ontology of physicalism.
Conscious realism pins the decline where it belongs—on our interface, not on an unconscious objective reality. Although each successive icon, in the sequence from human through ant to quark, offers a dimmer view of the conscious world that lies behind, this does not entail that consciousness itself is on a dimmer switch. The face I see in a mirror, being an icon, is not itself conscious. But behind that icon flourishes, I know firsthand, a living world of conscious experiences. Likewise, the stone I see in a riverbed, being an icon, is not conscious nor inhabited by consciousness.
---
Conscious realism contends, to the contrary, that no physical object is conscious. If I see a rock, then that rock is part of my conscious experience, but the rock itself is not conscious. When I see my friend Chris, I experience an icon that I create, but that icon itself is not conscious. My Chris-icon opens a small portal into the rich world of conscious agents; a smiling icon, for instance, suggests a happy agent. When I see a rock, I also interact with conscious agents, but my rock-icon offers no insight, no portal, into their experiences.
So conscious realism reframes the AI question: Can we engineer our interface to open new portals into the realm of conscious agents? A hodgepodge of transistors affords no insight into that realm. But can transistors be assembled and programmed into an AI that opens a new portal into that realm? For what it’s worth, I think so. I think that AI can open new portals into consciousness, just as microscopes and telescopes open new vistas within our interface.
In §24 of the Encyclopedia Logic [Hegel] claims that “logic coincides with metaphysics, with the science of things grasped in thoughts” (EL 56/81), and in the introduction to the Logic he maintains that “the objective logic . . . takes the place . . . of former metaphysics which was intended to be the scientific construction of the world in terms of thoughts alone” (SL 63/1: 61). Hegel also emphasizes the metaphysical character of the Logic by asserting that its subject matter is the logos, “the reason of that which is”: “it is least of all the logos which should be left outside the science of logic” (SL 39/1: 30)…
Hegel does not claim that ontological structures are known in the Logic precisely as they occur in nature. The Logic conceives such structures in abstraction from space, time, and matter first of all, and the Philosophy of Nature then examines how such structures manifest themselves in space and time. Hegel’s claim that conceptual and syllogistic form is to be found in nature (or in “all things”) should not therefore be taken to blur the distinction between the Logic and the Philosophy of Nature. What that claim does make clear, however, is that for Hegel “concept” and “syllogism” are forms inhering in what there is and are not just forms in terms of which we think; they are ontological and not merely logical structures.
---
Hegel’s arguments in support of the claim that thought understands not just the objects of our experience but being itself can be regarded as forming his own Transcendental Deduction....
There are two intimately related arguments at the heart of Hegel’s Transcendental Deduction. After Kant’s critical turn, Hegel maintains, the logician is no longer justified in taking for granted any rules, laws, or concepts of thought (SL 43/1: 35). Indeed, the logician cannot take for granted anything at all about thought except thought’s own simple being. In the science of logic, therefore, we may begin from nothing more determinate than the sheer being of thought itself—thought as sheer being.
...The principal difference between Descartes and Hegel, of course, is that for Hegel the process of suspending all that thought has previously taken for granted about itself leaves us not with the recognition that I am but with the indeterminate thought of thought itself as sheer being.
Hegel’s second argument is equally simple but starts from the idea of “being” rather than from thought. If we are to be thoroughly self-critical, we cannot initially assume that being is anything beyond the being of which thought is minimally aware. We may not assume that being stands over against thought or eludes thought but must take being to be the sheer immediacy of which thought is minimally aware—because that is all that the self-critical suspension of our presuppositions about being and thought leaves us with. A thoroughly selfcritical philosopher has no choice, therefore, but to equate being with what is thought and understood. Any other conception of being—in particular, one that regards being as possibly or necessarily transcending thought—is simply not warranted by the bare idea of being as the “sheer-immediacy-of-which-thoughtis-minimally-aware” from which we must begin.
First, we are aware of being for no other reason than that we think; thought is thus the “condition” of our awareness of being. This is Hegel’s quasi-Kantian principle. Second, thought is minimally the awareness or intuition of being itself. This is Hegel’s quasiSpinozan principle. These two principles dovetail in the single principle that the structure of being is the structure of the thought of being and cause Hegel to collapse ontology and logic into the new science of ontological logic. 31
Hegel acknowledges that there is a difference between thought and being: being is what it is in its own right and is not there only for conscious thought. Moreover, as we learn in the course of the Logic, being does, after all, turn out to constitute a realm of objects (“over there” and all around us). Hegel insists, however, that we may not begin by assuming that being is quite separate from thought.

Is the rampant humanism disturbing ? Is such humanism created here or merely unveiled? I think I'm just making the rationalism that was always central explicit. I grant that embracing it gives it a different feel.
After Wittgenstein, the standard response is that there is nothing you can say about this "base reality". The corollary, that it therefore drops out of any discussion; it is irrelevant.
So back to plain ordinary reality, socks and hands and cups and kettles.
For an example of such ill effects, consider someone interested in the privacy of sensations who asks the following question, and who struggles to find any satisfactory answer: ‘Why can nobody else know with the certainty I do whether I feel pain?’ On Wittgenstein’s view, if we attend to the way in which sentences like ‘I feel pain’ are actually used, then this will appear akin to someone grappling with the gibberish: ‘Why can nobody else know with the certainty I do whether ouch!?’ Philosophy can be used to show that there is no real problem here.
In particular, Wittgenstein went to some length to point out that language is embedded in out activities, and certainly not "too distinct, too cut off from the rest of experience"
PI 114(Tractatus Logico-Philosophicus, 4.5): "The general form of propositions is: This is how things are."——That is the kind of proposition that one repeats to oneself countless times. One thinks that one is tracing the outline of the thing's nature over and over again, and one is merely tracing round the frame through which we look at it.
PI 126One might also give the name "philosophy" to what is possible before all new discoveries and inventions.
PI 116The results of philosophy are the uncovering of one or another piece of plain nonsense and of bumps that the understanding has got by running its head up against the limits of language. These
bumps make us see the value of the discovery.
The question "What is a word really?" is analogous to "What is a piece in chess?"
It was true to say that our considerations could not be scientific ones. It was not of any possible interest to us to find out empirically 'that, contrary to our preconceived ideas, it is possible to think suchand-such'—whatever that may mean. (The conception of thought as a gaseous medium.) And we may not advance any kind of theory. There must not be anything hypothetical in our considerations. We must do away with all explanation, and description alone must take its place. And this description gets its light, that is to say its purpose, from the philosophical problems. These are, of course, not empirical problems; they are solved, rather, by looking into the workings of our language, and that in such a way as to make us recognize those workings: in despite of an urge to misunderstand them. The problems are solved, not by giving new information, but by arranging what we have always known. Philosophy is a battle against the bewitchment of our intelligence by means of language.
And he might well have agreed with you that it is impossible to avoid metaphysics, being what is shown rather than just said.
If so, then there are standing waves.
What makes the structure physical and not mathematical? That is a question that we refuse to answer. In our view, there is nothing more to be said about this that doesn’t amount to empty words and venture beyond what the PNC allows. The ‘world-structure’ just is and exists independently of us and we represent it mathematico-physically via our theories. (158)
So you would build another, somewhat larger bottle
This brings me to the second way that I think HW’s metaphilosophy overgeneralizes. According to HW, philosophy is purely descriptive; it should “leave the world as it is” — only describe how we think and talk, and stop at that.
I think philosophy can play a more radical role. Return to our fly. Wittgenstein was not the first to compare the philosopher to one, nor the most famous. That award goes to Socrates, who claimed that the role of the philosopher was to act as a gadfly to the state. This is a very different metaphor. Leaving the world as it is isn’t what gadflies do. They bite. As I see it, so can philosophers: they not only describe how we think, they get us to change our way of thinking — and sometimes our ways of acting. Philosophy is not just descriptive: it is normative.
As he points out, philosophers traditionally assumed that truth has a single nature — something all true statements share. Some said that all truths correspond to reality, others that all truths are useful, or are rationally coherent, and so on. Each one of these views falls short. Not every truth is useful, nor does every truth — think of the fundamental truths of morality or mathematics — clearly correspond to an objective reality. In HW’s eyes, we got ourselves into this mess by ignoring the real function of the concept, which isn’t to pick out some deep property all and only true statements share, but to allow linguistic shortcuts. And that is all there is to it: seeing that there is no “nature” to truth is the way out of the fly bottle...
First, just because we can’t reductively (“scientifically”) define something doesn’t mean we can’t say something illuminating about it. Go back to HW’s account of truth. He assumes that there is either a single nature of truth (and we can reductively define it) or that truth has no nature at all. But why think these are the only two choices?
