Wittgenstein is undoubtedly one of the central figures in twentieth-century philosophy of language. Whether in the early Tractatus Logico-Philosophicus, where language is understood through its logical relation to the world, or in the later Philosophical Investigations, where meaning is returned to use, language-games, and forms of life, he changed the direction of modern philosophy in a decisive way. Yet precisely here lies the problem. Wittgenstein saw the danger of language with unusual clarity, but his philosophy also helped produce a deeper displacement. Language was no longer merely a tool through which human beings understand the world. It gradually became the horizon within which the world itself could be philosophically approached.
Strictly speaking, Wittgenstein did not present himself as someone constructing a new ontology. In his later philosophy, he even resisted the traditional metaphysical impulse and treated philosophy as a kind of therapy. Its task was to dissolve confusions generated by the misuse of language. But the effect of a philosophical method is not always identical with the philosopher’s declared intention. Once philosophical problems are repeatedly reduced to grammar, usage, expression, or language-games, language begins to acquire a quasi-ontological position. It stops being one instrument among others and becomes the final condition for whether a problem can be meaningfully discussed at all.
This is my most fundamental reservation about Wittgenstein’s philosophy of language. He noticed that language can mislead philosophy, but he moved too far toward making philosophical inquiry return to language itself. Philosophy no longer faces being, consciousness, freedom, value, and truth directly, but keeps returning to the question of how we speak about them. This may appear cautious, but it can also become a form of retreat. A philosophy that only diagnoses problems as linguistic illness may avoid the more difficult task of explaining why those problems arise from real structures of life, body, world, and experience.
From the perspective of Sustenesis Theory, language is neither the ground of being nor nothingness. The theory begins from Difference, Constraint, and Sustained Coherence. Difference makes more than one relation, state, or transformation possible. Constraint limits, selects, or shapes what can form next. Sustained Coherence occurs when the constitutive relations of an organisation continue, or are compatibly re-formed, through actual dependence across ordered formation. Language is one relational medium within such processes. It preserves differences, invokes experience, organizes judgment, and guides action, but it neither copies reality completely into symbols nor generates meaning inside a closed symbolic world.
The limitation of language therefore does not mean that philosophical problems are merely linguistic problems. Language is indeed like an imprecise ruler. When it attempts to measure an absolute value, it often fails. Concepts such as freedom, justice, consciousness, and goodness are difficult to define with mathematical precision. But this does not mean that they are empty. Very often, language cannot provide an absolute definition, yet it can still present differences in a stable and meaningful way. We may not be able to define absolute justice once and for all, but we can often judge that one institution is more unjust than another. We may not be able to exhaust the essence of freedom, but we can still recognize that coercion, oppression, and deprivation reduce freedom.
This point is crucial. A ruler may itself be inaccurate. Its scale may contain a deviation, so when we use it to measure a single object, we may not obtain its absolute length. But if we use the same ruler to measure two objects, it can still tell us which one is longer, which one is shorter, and roughly how large the difference is between them. Language works in a similar way. It may not tell us what justice, freedom, or consciousness is in an absolute ontological sense, but within the same context, the same field of experience, and the same structure of constraints, it can allow us to compare different institutions, actions, and states of consciousness.
This metaphor separates linguistic problems from genuine philosophical problems. The imprecision of language can certainly distort philosophical expression and generate many pseudo-problems. But the imprecision of language does not imply that the structures of reality do not exist. Nor does it imply that philosophy must retreat entirely into language. Language may fail to provide an absolute scale, but it can still support valid comparison. It may not capture the ultimate essence of a concept, but it can help us identify difference, direction, constraint, and structural relation.
In this sense, Saussure’s claim that language contains only differences and no positive terms can be understood in a broader philosophical way. Meaning is not always derived from the isolated essence of a word. It often arises from a network of differences among words, experiences, and practices. We do not need to grasp the absolute essence of red before we can distinguish red from blue or yellow. In the same way, we do not need to possess the final definition of justice before we can judge that some arrangements are more unjust than others. Meaning is not a static object. Structurally, it lies in a difference's position within a relational organisation and in the consequences that position has for further formation.
The validity of philosophy therefore does not depend on the absolute precision of language. Wittgenstein’s later philosophy rightly reminded us that meaning is embedded in use and forms of life. But if philosophy becomes too absorbed in how the ruler is made, it may forget that even an imperfect ruler can still reveal relative differences in the world. Language is imperfect, but that does not make it useless. Language cannot deliver absolute definitions, but that does not prevent it from helping us approach reality.
Sustenesis Theory is concerned precisely with how such differences are preserved, invoked, tested, and corrected. A linguistic concept exists when its constitutive differentiated relations continue to be realised; its structural meaning lies in a difference's position within a relational organisation and in the efficacy that position has for further formation. When a linguistic relation formed through Difference under Constraint acquires actual constraining efficacy over later thought or action, it exhibits Structural Reflexivity. None of this makes the concept true merely because it persists. Truth concerns whether a domain-directed structure remains appropriately constrained by the object relations to which it refers; testing and correction concern how that relation is examined and revised.
Wittgenstein’s problem is that he emphasized the internal rules of language-use without sufficiently explaining why those rules are able to stabilize at all. Language-games exist. Forms of life matter. But a form of life is not produced by language alone. Behind it there are bodies, biological structures, shared experience, the resistance of the physical world, institutional consequences, and long-term social practices. If these constraints are weakened, language-games begin to float as symbolic activities, as though different communities were merely playing different games and we could no longer ask which claims remain answerable to object relations, which practices affect conscious subjects, or what each system actually sustains at its own scale.
This creates the danger of linguistic relativism. Science, religion, myth, moral judgment, and political narrative can all be described as different language-games. But Sustenesis Theory cannot accept this flattening. Different systems of language certainly operate by different rules, yet persistence and internal coherence do not make them equally true or reliable. Where a discourse is directed at an object-domain, its claims must remain exposed to constraints capable of producing a truth/error distinction. Verification tests that relation; justification and reliability concern why a claim may be depended upon. Effective operation may provide evidence within a stated scope, but it cannot substitute for truth.
This is also the key to the problem of linguistic recursion. If language seeks its ground only inside itself, it can fall into endless explanation. One word requires another word, and that word requires yet another. Concepts may define one another indefinitely, but this process cannot automatically produce a real ground. A dictionary-like loop in which A is defined by B, B by C, and C returns to A is a conceptual loop: a dependency among explanations that fails to disclose what constrains their reference. It must not be confused with Structural Reflexivity, which is an ordered and actual process in which a relation previously formed through Difference under Constraint re-enters as a constraint on later formation. Conceptual circularity can hide a missing ground; structural return can be a real mechanism.
At a deeper level, any complex symbolic system that is sealed entirely within itself struggles to establish its own final ground. Gödel’s incompleteness theorem is a result within mathematical logic and should not be casually converted into a proof about language as a whole. Yet philosophically, it does suggest that a sufficiently complex formal system cannot easily secure completeness and consistency solely from within itself. If language is treated as the only ontological system, it faces an analogous difficulty. It can explain, repair, translate, and extend itself, but it cannot obtain its final ground from itself alone. To make language the only ontology is therefore not caution. It is a path that cannot truly converge.
For language to terminate this recursion, it must encounter an external dimension. This external dimension is not mysterious. It includes the physical world, the practices through which human beings survive, the biological structure of the brain and body, the institutional consequences of common life, and the repeated correction of concepts by lived experience. Measurement begins only when the ruler touches something that resists it. Otherwise, language remains a movement from word to word.
Here, pragmatism and later holistic accounts of knowledge offer useful references. Quine’s metaphor of the web of belief is especially relevant. Logic and mathematics may lie closer to the center of the web, but the edges of the web must still touch experience. Language and knowledge are not isolated sets of sentences, yet neither are they the same thing. Knowledge requires a domain-directed structure in which object constraints can generate a truth/error distinction. Understanding requires the further capacity to reconstruct relevant constraints, explain how a result is formed, recognise its limits, and transfer it into new contexts. A web may help preserve both, but internal consistency and survival alone establish neither.
Pain is a clear example. We can discuss how the word pain is used, and we can compare how different cultures express suffering. But pain itself is not manufactured by a language-game. When a person is injured, the neural response, bodily contraction, fear, and impulse to withdraw precede linguistic explanation. Moral concepts are similar. Good and evil may be expressed differently by different traditions, but harm, fear, humiliation, empathy, dependence, cooperation, and betrayal are not arbitrary products of language. Language can interpret them, organize them, and institutionalize them, but it does not create them from nothing.
When we discuss a highly abstract concept such as morality, the non-linguistic factors that interrupt recursion are not a single object but several constraints working together. Pain, fear, empathy, dependence, and security involve real conditions of conscious subjects; cooperation, trust, commitment, punishment, and reputation involve durable social relations; actions and institutions have consequences that can benefit or harm those subjects. These relations keep moral language from being arbitrary. They do not, by their mere persistence, derive an ought from structural fact. A moral judgment still requires an explicit bridge commitment identifying the affected moral patients and the sustenetic conditions to be protected. Here moral patients include conscious subjects for whom changes in sustenetic conditions can constitute experiential or life-course benefit or harm, beings developing through causal continuity into such subjects, and subjects whose consciousness is temporarily interrupted while they remain causally continuous as the same subject.
The same applies to free will. Language can analyze how the word freedom is used, but rules of usage cannot decide whether an action subject actually has alternatives under relevant constraints, can inhibit a response, can revise direction through feedback, or bears responsibility under conditions of control, knowledge, and avoidability. These are structural and empirical questions before they are verbal ones. Linguistic comparison helps us formulate them; it cannot settle them by itself.
Consciousness also cannot be compressed into language. Language can analyze how the word consciousness is used, but first-person presence does not require linguistic permission. Pain, hesitation, choice, regret, and expectation are not produced only after they have been defined in words. Language can stabilize and express these experiences, but it is not their condition of existence. If Wittgensteinian therapy goes too far, it reduces subjectivity to expressive rules and avoids the deeper question of consciousness as a sustenetic relation.
In Sustenesis Theory, consciousness is neither a mysterious entity hidden behind language nor a pseudo-problem that can be dissolved by linguistic analysis. Under the complete criterion stated in the Glossary, R2 consciousness is difference-preserving whole reflexivity: within the same update window, results from multiple relatively independent formation chains jointly form a current relation, their differentiated contributions remain jointly effective, and that whole relation constrains the chains’ further formation. R1 coordination remains reproducible by local, pairwise, or centre–branch constraint relations. A centre–branch model counts as an R1 decomposition only when its centre merely aggregates or relays separable contributions without retaining the differentiated joint configuration that would realise the candidate whole; renaming that whole as a centre does not decompose it. At R2, the whole has content-sensitive, cross-chain efficacy that those decomposed relations cannot reproduce while all participating chains and their relevant local capacities are retained. Reproduction is judged at a specified scale, across a stated intervention family, and within empirically justified tolerances. The counterfactual intervention must alter or remove the common relation without merely disabling the chains; if decomposed paths reproduce the relevant cross-chain effects under those conditions, the organisation remains R1 rather than R2. Its conscious-subject boundary is maximal only relative to the same update window, specified scale, and counterfactually closed candidate whole; nested or overlapping R2 candidates are evaluated separately. Language may enter this whole relation and can greatly enlarge reflection and self-consciousness, but language, feedback, integration, self-description, or institutional recursion alone does not establish consciousness. An infant, an animal, or a person without developed linguistic expression is therefore not excluded by definition.
Social practice is another important anchor beyond language. The meaning of a concept cannot be judged only by how it appears in sentences; its consequences within action and institutions also matter. Law does not exist merely because people use the word law. Its constitutive relations among procedures, sanctions, expectations, and power must be actually formed and continuously realised; their constraint on conduct is one consequence and source of evidence. Earlier decisions can become constraints on later decisions, giving an institution Structural Reflexivity. That institutional return does not by itself create a single conscious subject. It identifies an ordered social mechanism, not an experiential whole.
This is the fundamental difference between Sustenesis Theory and Wittgenstein’s method. Wittgenstein sees many philosophical illnesses as misuses of language. Sustenesis Theory asks how relations form through Difference under Constraint, how formed relations re-enter later formation, and how their constitutive organisation achieves Sustained Coherence. Language is only one part of this process. It can preserve true claims or knowledge, but it can also produce illusion. It can support understanding, but it can also increase recursive confusion. Its epistemic force cannot be judged only by conformity to grammatical rules; it depends on whether its domain-directed relations remain open to testing and correction under real constraints.
This does not deny Wittgenstein’s value. His insight was real. He showed that language profoundly shapes philosophical problems and that many confusions are indeed generated by words. But his limitation lies in his failure to distinguish clearly enough between the limiting role of language and the ontological status of language. Language shapes understanding and expression, but it is not the final ground of the world. It can determine how we enter a problem, but it cannot determine whether the problem itself exists.
Philosophy cannot remain inside language. It must acknowledge the imprecision of language, while also acknowledging that beyond language there are bodies, worlds, actions, institutions, consciousness, and value-constraints. Philosophy should not deny the object measured because the ruler is imperfect. Nor should it abandon the pursuit of reality because language can produce illusion. The better path is to return language to its proper place. Language is a tool within a sustenetic system, a medium, a mechanism for preserving difference, a way of invoking reality, but it is not being itself.
Language is an indispensable tool for human philosophy. In many cases, it is the primary tool through which human beings think philosophically at all. But the limitation of the tool does not imply the emptiness of ontology. We cannot conclude that the world is immeasurable because the ruler is imprecise. Nor should we spend our entire philosophical life studying the ruler simply because the ruler is important. The task of philosophy is to understand how, through imperfect tools, we gradually approach the contours of a real external world under the constraints of body, experience, action, and reality.
Wittgenstein helped bring philosophy back from certain illusions of traditional metaphysics. That was his contribution. But if philosophy becomes trapped inside language as a result, it has only moved from one illusion to another. Language is neither prison nor throne. It is an imperfect but useful ruler. The task of philosophy is not to worship the ruler, nor to destroy it, but to use it while facing the real world that continually constrains, corrects, and demands revision from our understanding.
