The primary aim of this paper is to provide the exact diagnosis of the contingent a priori debate so far by untangling complicated issues surrounding it, such as singular thought, linguistic stipulation, and epistemic justification. I will first maintain that most philosophers' arguments for or against the contingent a priori are ultimately based on one of two conflicting intuitions about linguistic stipulation: sceptics of the contingent a priori have appealed to the intuition that extra-linguistic knowledge cannot be acquired through the (...) stroke of a pen, whereas proponents of it have appealed to the other intuition that one is in a position to understand a name that one introduces by oneself into one's own language. Then I will reconstruct the sceptics' and proponents' positions in their strongest form respectively and examine where they disagree, and finally I will argue that the contingent a priori debate cannot help but end in a stalemate without further scrutiny into singular thought. From this diagnosis, I conclude that in order to appropriately judge whether a contingent proposition is knowable a priori, we must first independently investigate what the conditions for singular thought are: the contingent a priori rides on the singular thought debate.

It is widely accepted among philosophers that there is a tension between acquaintance constraints on singular thought and the plausible assumption that the truths of singular attitude reports ensure the subject's having singular thoughts. From this, anti-acquaintance theorists contend that acquaintance constraints must be rejected. As a response, many acquaintance theorists maintain that there is good reason to doubt a strong connection between singular attitude reports and singular thoughts. In this paper, however, I defend the acquaintance theory by arguing that (...) there is in fact no tension at all. I consider three objections regarding singular attitude reports against the acquaintance theory: (i) ultra-liberal singular attitude reports, (ii) the “There is something that S believes to be F” locution, and (iii) infelicities of singular attitude reports. Then, I argue that none of them succeed in showing a genuine tension. (shrink)

Among philosophers, Fregeanism and sententialism are widely considered two of the leading theories of the semantics of attitude reports. Among linguists, these approaches have received little recent sustained discussion. This paper aims to bridge this divide. I present a new formal implementation of Fregeanism and sententialism, with the goal of showing that these theories can be developed in sufficient detail and concreteness to be serious competitors to the theories which are more popular among semanticists. I develop a modern treatment of (...) quantifying in for Fregeanism and sententialism, in the style of Heim and Kratzer, and then show how these theories can—somewhat surprisingly—account for “third readings” on the model of the “Standard Solution” from possible-worlds semantics. The resulting Fregean/sententialist proposal has a distinctive attraction: it treats data related to counterfactual attitudes —which have proven challenging to accommodate in the setting of possible worlds semantics—straightforwardly as third readings.

This paper presents an extension of Putnam's account of how substance terms such as ‘water’ and ‘gold’ function and of how a posteriori necessary truths concerning the underlying microstructures of such kinds may be derived. The paper has three aims. I aim to refute a familiar criticism of Putnam's account: that it presupposes what Salmon calls an ‘irredeemably metaphysical, and philosophically controversial, theory of essentialism’. I show how all of the details of Putnam's account—including those that Salmon believes smuggle in (...) such essentialist commitments—can be squared with a rejection of any such essentialist metaphysics. I aim to reveal why Steward is wrong to suppose that, by helping himself to the claim that ‘H2O’ is a rigid designator of a substance, Kripke, too, presupposes something controversially ‘metaphysical’. I aim to show how my proposed account also sidesteps a variety of objections raised by Needham and others who argue that Kripke's and Putnam's accounts of how ‘water’ and.. (shrink)

Arthur Prior’s argument for the A-theory of time in “Thank Goodness That’s Over” is perhaps his most famous and well-known non-logical work. Still, I think that this paper is one of his most misunderstood works. Because of this, much of its brilliance has yet to be properly appreciated. In this paper, I suggest that the explanation of this is that it has been treated as though it were following the standard model for a piece of Analytic philosophy. That is, it (...) has been assumed that what Prior was doing was deductively demonstrating the truth of a proposition which can be discussed via any sentences with the same semantic content. Here, I argue that this assumption is wrong on two fronts: Most importantly, the strongest reading of the structure of Prior’s argument is as an abduction rather than as a deduction. Many of the most important lessons of the argument are lost by focusing on the bare propositional content of its premise and conclusion statements. In other words, we can learn as much from the manner in which this argument is presented and expressed as we can from that which is expressed. (shrink)

Recent arguments for relativist semantic theories have centered on the phenomenon of “faultless disagreement.” This paper offers independent motivation for such theories, based on the interpretation of predicates of personal taste in certain attitude contexts and presuppositional constructions. It is argued that the correct interpretation falls out naturally from a relativist theory, but requires special stipulation in a theory which appeals instead to the use of hidden indexicals; and that a hidden indexical analysis presents problems for contemporary syntactic theory.

I argue that sentence contents should be assigned truth-values relative to parameters other than a possible world only if those parameters are fixed by the context of assessment rather than the context of use. Standard counterexamples, including tense, de se attitudes, and knowledge ascriptions, all admit of alternative analyses which do not make use of such parameters. Moreover, allowing such indices greatly complicates the task of defining disagreement, and forces an odd separation between what is true, and what someone has (...) truthfully said. If non-world indices are always fixed by the context of assessment, a characterization of semantic theories as ?relativist? in terms of assessment-sensitivity converges with a characterization in terms of sensitivity to non-world indices. More tentatively, I suggest that even a possible world index, when used in the assignment of truth-values to sentence contents, should be fixed by the context of assessment, not the context of use. This eliminates MacFarlane's category of ?non-indexical contextualism?, and results in a system in which parameters fixed by the context of use are used only in the assignment of contents to linguistic expressions, and parameters used in the assignment of truth-values to contents are uniformly fixed by the context of assessment.

I look at incompatibilist arguments aimed at showing that the conjunction of the thesis that a subject has privileged, a priori access to the contents of her own thoughts, on the one hand, and of semantic externalism, on the other, lead to a putatively absurd conclusion, namely, a priori knowledge of the external world. I focus on arguments involving a variety of externalism resulting from the singularity or object‐dependence of certain terms such as the demonstrative ‘that’. McKinsey argues that incompatibilist (...) arguments employing such externalist theses are at their strongest, and conclusively show that privileged access must be rejected. While I agree on the truth of the relevant externalist theses, I show that all plausible versions of the incompatibilist reductio argument as applied to such theses are fundamentally flawed, for these versions of the argument must make assumptions that lead to putatively absurd knowledge of the external world independently of the thesis of privileged access.

This paper argues that truth values of sentences containing predicates of “personal taste” such as fun or tasty must be relativized to individuals. This relativization is of truth value only, and does not involve a relativization of semantic content: If you say roller coasters are fun, and I say they are not, I am negating the same content which you assert, and directly contradicting you. Nonetheless, both our utterances can be true (relative to their separate contexts). A formal semantic theory (...) is presented which gives this result by introducing an individual index, analogous to the world and time indices commonly used, and by treating the pragmatic context as supplying a particular value for this index. The context supplies this value in the derivation of truth values from content, not in the derivation of content from character. Predicates of personal taste therefore display a kind of contextual variation in interpretation which is unlike the familiar variation exhibited by pronouns and other indexicals. (shrink)

Perception is a central means by which we come to represent and be aware of particulars in the world. I argue that an adequate account of perception must distinguish between what one perceives and what one's perceptual experience is of or about. Through capacities for visual completion, one can be visually aware of particular parts of a scene that one nevertheless does not see. Seeing corresponds to a basic, but not exhaustive, way in which one can be visually aware of (...) an item. I discuss how the relation between seeing and visual awareness should be explicated within a representational account of the mind. Visual awareness of an item involves a primitive kind of reference: one is visually aware of an item when one's visual perceptual state succeeds in referring to that particular item and functions to represent it accurately. Seeing, by contrast, requires more than successful visual reference. Seeing depends additionally on meta-semantic facts about how visual reference happens to be fixed. The notions of seeing and of visual reference are both indispensable to an account of perception, but they are to be characterized at different levels of representational explanation. (shrink)

Kripke’s examples of allegedly contingent a priori sentences include ‘Stick S is exactly one meter long’, where the reference of ‘meter’ is fixed by the description ‘the length of stick S’. In response to skepticism concerning apriority Kripke replaced the meter sentence with a more sophisticated variant, arguing that the modified example is more immune to such skepticism. The case for apriority is examined. A distinction is drawn between apriority and a broader notion, “qua-priority,” of a truth whose epistemic justification (...) is dependent on no experience other than that required to justify belief of the deliverances of pure semantics. It is argued that Kripke’s examples are neither a priori nor qua-priori. (shrink)

[This is an earlier (1997), much longer and more detailed version of my entry on LOTH in the _Stanford Encyclopedia of Philosophy_] The Language of Thought Hypothesis (LOTH) is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, thought is, roughly, the tokening of a representation that (...) has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking. (shrink)

The aim of this paper is to discuss a seemingly straightforward argument against physicalism which, despite being implicit in much of the philosophical debate about consciousness, has not received the attention it deserves (compared to other, better-known “epistemic”, “modal”, and “conceivability” arguments). This is the argument from the non-supervenience of the first-personal (and indexical) facts on the third-personal (and non-indexical) ones. This non-supervenience, together with the assumption that the physical facts (as conventionally understood) are third-personal, entails that some facts – (...) namely, first-personal, phenomenal ones – do not supervene on the physical facts. Unlike other arguments against physicalism, the first-personal argument, if successful, refutes not only physicalism but also other third-personal metaphysical pictures, including standard versions of dualism.

Over the past few years, the tree model of time has been widely employed to deal with issues concerning the semantics of tensed discourse. The thought that has motivated its adoption is that the most plausible way to make sense of indeterminism is to conceive of future possibilities as branches that depart from a common trunk, constituted by the past and the present. However, the thought still needs to be further articulated and defended, and several important questions remain open, such (...) as the question of how actuality can be understood and formally represented in a branching framework. The present volume is intended to be a 360 degree reflection on the tree model. The contributions is gathers concern the model and its alternatives, both from a semantic and from a metaphysical point of view. ​. (shrink)

This book presents novel formalizations of three of the most important medieval logical theories: supposition, consequence and obligations. In an additional fourth part, an in-depth analysis of the concept of formalization is presented - a crucial concept in the current logical panorama, which as such receives surprisingly little attention.Although formalizations of medieval logical theories have been proposed earlier in the literature, the formalizations presented here are all based on innovative vantage points: supposition theories as algorithmic hermeneutics, theories of consequence analyzed (...) with tools borrowed from model-theory and two-dimensional semantics, and obligations as logical games. For this reason, this is perhaps the first time that these medieval logical theories are made fully accessible to the modern philosopher and logician who wishes to obtain a better grasp of them, but who has always been held back by the lack of appropriate ‘translations' into modern terms.Moreover, the book offers a reflection on the very nature of logic, a reflection that is prompted by the comparisons between medieval and modern logic, their similarities and dissimilarities. It is thus a contribution not only to the history of logic, but also to the philosophy of logic, the philosophy of language and semantics.The analysis of medieval logic is also relevant for the modern philosopher and logician in that, being the unifying methodology used across all disciplines at that time, logic really provided unity to science. It thus presents a unified model of scientific investigation, where logic plays the aggregating role. (shrink)

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed.

Contextualism is the view that knowledge ascriptions – utterances of sentences containing the word “knows” - express different propositions in different contexts of utterance. But what features of context determine the propositions expressed by knowledge ascriptions? According to a version of contextualism I call conversational contextualism, the conversational dynamics or kinematics determine the propositions expressed by knowledge ascriptions. In this paper I argue that the most sophisticated version of conversational contextualism, which is the view defended by Michael Blome-Tillmann (2009; 2014), (...) faces serious problems. My (very) tentative conclusion will be that conversational contextualism should be abandoned because of these problems. (shrink)

According to a widespread picture due to Kaplan, there are two levels of semantic value: character and content. Character is determined by the grammar, and it determines content with respect to context. In this chapter Recanati criticizes that picture on several grounds. He shows that we need more than two levels, and rejects the determination thesis: that linguistic meaning as determined by grammar determines content. Grammatical meaning does not determine assertoric content, he argues, but merely constrains it — speaker’s meaning (...) necessarily comes into play. On the alternative picture he offers, there are four basic levels, only one of which is determined by the grammar. Pragmatics is what enables the transition from each level to the next. (shrink)

As a main challenge to the growing block theory (GBT), the epistemic objection is intended to show that GBT is untenable because it leads to the ignorance of the objective present. What is worse, extant solutions to this objection, the dead past view (DPV) and strong tense views (STV), are unsatisfactory on the ground that their semantic explanations of tensed statements undermine the purported semantic unity of GBT and thus make GBT collapse into a version of presentism. In contrast to (...) extant solutions, I recommend growing blockists to adopt a new “biting the bullet” solution: They should accept the ignorance of the absolute present for the dual purpose of retaining GBT’s semantic unity and theoretical independence. Moreover, I argue that ignorance is not a big loss for growing blockists: Although they lose the so-called “Moorean common advantage” over B-theorists and include some “deeply mysterious” and epistemically inaccessible fundamental posit in their ontology, growing blockists thereby protect the semantic unity of their theory and most of ordinary knowledge about B-relations between moments of time and their temporal locations. Theory choice, in essence, is a matter of balancing benefits and costs. I believe that versions of GBT which accept the ignorance of the objective present are indeed tenable intermediate positions in the philosophical debate about the nature of time, and they deserve serious considerations of B-theorists.

Two-dimensional (2D) semantics is a formal framework that is used to characterize the meaning of certain linguistic expressions and the entailment relations among sentences containing them. 2D semantics has also been applied to thought contents. In contrast with standard possible worlds semantics, 2D semantics assigns extensions and truth-values to expressions relative to two possible world parameters, rather than just one. So a 2D semantic framework provides finer-grained semantic values than those available within standard possible world semantics, while using the same (...) basic model-theoretic resources. The 2D framework itself is just a formal tool. To develop a semantic theory for someone’s language, a proponent of 2D semantics must do three things: (i) explain what exactly the two possible world parameters represent, (ii) explain the rules for assigning 2D semantic values to a person’s words and sentences, and (iii) explain how 2D semantic values help in understanding the meanings of the person’s words and sentences.

Crispin Wright and Filippo Ferrari have accused relativism of not accounting for “parity” – the idea that, when we argue over matters of taste, we take our opponents’ opinions to be “as good as ours” from our own, committed perspective.

In this discussion paper, I argue that no theory of consciousness can simultaneously respect four initially plausible metaphysical claims – namely, “first-person realism”, “non-solipsism”, “non-fragmentation”, and “one world” – but that any three of the four claims are mutually consistent. So, theories of consciousness face a “quadrilemma”. Since it will be hard to achieve a consensus on which of the four claims to retain and which to give up, we arrive at a landscape of competing theories, all of which have (...) pros and cons. I will briefly indicate which kinds of theories correspond to the four horns of the quadrilemma. (shrink)

In Overlooking Conventions Michael Devitt argues in defence of the traditional approach to semantics. Devitt’s main line of argument is an inference to the best explanation: nearly all cases that linguistic pragmatists discuss in order to challenge the traditional approach to semantics are better explained by adding conventions into language, in the form of expanding the range of polysemy or the range of indexicality (in the broad sense of linguistically governed context sensitivity). In this paper, we discuss three aspects of (...) a draft of Devitt’s Overlooking Conventions, which was discussed at a conference in Dubrovnik in September 2018. First, we try to show that his rejection of Bach’s distinction between convention and standardization overlooks important features of standardization. Second, we elaborate on Devitt’s argument against linguistic pragmatism based on the normative aspect of meaning and show that a similar argument can be mounted against semantic minimalism. While Devitt and minimalists have a common enemy, they are not allies either. Third, we address a methodological difficulty in Devitt’s view concerning a threat of over-generation and propose a solution to it. Although this paper is the result of collaboration the authors have written different parts. Carlo Penco has written part 1, Massimiliano Vignolo has written part 2 and part 3. (shrink)

The purpose of this article is to offer a new view of the key relation between the content and the conscious character of visual experience. The author aims to support the following claims. First, the author rejects the qualia realist claim that conscious character is an intrinsic, nonrepresentational property of visual experience, for example, a pattern of activation of neurons. However, the author also rejects the rival widespread representationalist claim that the conscious character of visual experience is identical to, or (...) supervenes on, any specific property represented by visual experience. The positive proposal is the following. Conscious character is identical to those patterns of activation of neurons that are referentially or representationally alive. Conscious redness, for example, is a pattern of activations of neurons that is normally created only when brains of physical duplicates come in visual contact with some distal property. This pattern of activation is recruited by natural selection to represent that property. This is called meaning representationalism. (shrink)

Epistemic contextualism (‘EC’), the view that the truth-values of knowledge attributions may vary with the context of ascription, has a variety of different linguistic implementations. On one of the implementations most popular in the early days of EC, the predicate ‘knows p’ functions semantically similarly to gradable adjectives such as ‘flat’, ‘tall’, or ‘empty’. In recent work Jason Stanley and John Hawthorne have presented powerful arguments against such implementations of EC. In this article I briefly systematize the contextualist analogy to (...) gradable adjectives, present Stanley’s argument against the analogy, and offer a contextualist response that abandons the analogy in favor of modeling the semantics of ‘knows p’ along the lines of quantifier expressions. I then present Hawthorne’s objection to the views presented, and finally conclude by outlining an argument to the effect that ‘knows p’ is an automatic indexical and as such to be expected to function differently from many other indexicals that the term has been compared to in the literature. I finally point out that no analogy should be expected to be perfect, and that no harm is done by postulating some unique behavior of ‘knows p’. (shrink)

I critically discuss some aspects of Mark Sainsbury's Reference without Referents, from an otherwise sympathetic viewpoint. My objections focus on the adequacy of the truth-conditional framework that Sainsbury presupposes. I argue that, as semantic theories, truth-conditional accounts are both too ambitious, and too austere to be fully explanatory, and that both problems have consequences for an account of reference. The latter problem has to do with the difficulties to capture in a truth-conditional framework the descriptive contribution of indexicals and, in (...) my view, proper names. The former has to do with the non-semantic contribution of context to the determination of truth-conditions in general and reference in particular. /// En este artículo discuto críticamente algunos aspectos del libro de Mark Sainsbury Reference without Referents, desde una perspectiva por lo demás próxima. Mis objeciones se centran en la adecuación del marco que Sainsbury presupone: la semántica de condiciones de verdad.

El segundo problema tiene que ver con las dificultades para representar la contribución descriptiva de los deícticos y, en mi opinión, de los nombres propios también en el marco de condiciones de verdad. El primero tiene que ver con la contribución no semántica del contexto a la determinación de las condiciones de verdad en general y la referencia en particular. (shrink)

There are at least three interpretations that attempt to read from the Sense-Certainty Chapter a Hegelian theory of indexicals. First, the Impossibility of Singular Reference Reading understands Hegel as excluding in principle the possibility of any linguistic cognition of individuals. Second, the Theory of Reference Reading criticizes the first reading and interprets from Hegel the classical idea of direct reference theory. Third, Brandom’s Anaphoric Theory Reading suggests an alternative explanation while still defending the possibility of knowledge of individuals in Hegel. (...) I criticize the first two readings and argue that the third is the most exegetically and philosophically adequate interpretation. The first interpretation attempts to ascribe to Hegel a sort of skepticism, but this can be at most in a very restricted sense successful and the skepticism constructed in such a way is too trivial to refute Hegel’s position. The second reading is more adequate in that it does not fall into the error that the first one committed, but is still flawed because it introduces a subject-object or mind-world dualism that Hegel denies. The third reading has great advantages compared to the first two readings in terms that it provides a suitable account of indexical knowledge on individuals while avoiding skepticism and dualism which arise in the former readings.

This paper is a new defense of the view that visual hallucinations lack content. The claim is that visual hallucinations are illusory not because their content is nonveridical, but rather because they seem to represent when they fail to represent anything in the first place. What accounts for the phenomenal character of visual experiences is not the content itself (content-representationalism), but rather the vehicle of content (vehicle-representationalism), that is, not the properties represented by visual experience, but rather the relational properties (...) of experience (or of the brain) of representing singular contents, namely particular instantiations of properties. I argue that the Russellian particular-involving proposition is the only appropriate model for the representational content of visual experience and hence that visual hallucinations are just like failed demonstrations.

The material account proposes that indicative conditionals are material, but it is widely believed that this account cannot be applied to subjunctive conditionals. There are three reasons for this consensus: (1) the concern that most subjunctive conditionals would be vacuously true if they were material, which seems implausible; (2) the inconsistency with Adams pair, which suggests that indicative and subjunctive conditionals have different truth conditions; and (3) the belief that the possible world theories are a superior alternative to the material (...) account. In this paper, I will argue against (1) by showing that the counterintuitive aspects of vacuously true conditionals can be explained away in a consistent manner, regardless of whether they are indicative or subjunctive. I will support this argument by demonstrating that the positive arguments for the material account of indicatives also apply to subjunctives. I will counter (2) by explaining the Adams pair as logically equivalent conditionals that may be appropriate at different times, depending on the speaker’s epistemic situation. Finally, I will challenge (3) by arguing that the possible world account faces insurmountable issues and that a comprehensive material account of both indicatives and subjunctives is ultimately a more elegant solution.

In the standard theory of deontic modals, ‘ought’ is understood as expressing a propositional operator. However, this view has been called into question by Almotahari and Rabern’s puzzle about deontic ‘ought’, according to which the ethical principle that one ought to be wronged by another person rather than wrong them is intuitively coherent but the standard theory makes it incoherent. In this paper, I take up Almotahari and Rabern’s challenge and offer a refinement of the standard theory to handle the (...) puzzle. I propose that ‘ought’ is evaluated relative to contextual parameters (e.g., Kratzer’s conversational backgrounds, Finlay and Snedegar’s alternative sets) and those contextual parameters are sensitive to agents as well as possible worlds.

A fairly simple theory of the semantics of tense is obtained by combining three claims: (i) for any time t, a present-tense sentence `p' is either true or false at t; (ii) for any time t0 earlier than t, the future-tense sentence `It will be the case that p at t' is true at t0 if `p' is true at t, false otherwise; (iii) for any time t0 later than t, the past-tense sentence `It was the case that p at (...) t' is true at t0 if `p' is true at t, false otherwise. This theory, which has been called the theory of timeless truth, is often dismissed on the basis of its alleged incapacity to comply with indeterminism. Here, instead, it will be suggested that there is no reason to be dismissive. Section 1 provides some elucidations about the theory. Sections 2 and 3 explain how a foregone objection to it can be resisted. Sections 4 and 5 show that there is a plausible sense in which (i)-(iii) are compatible with indeterminism. Sections 6 and 7 dispel some misunderstandings that may lead to think that indeterminism is not vindicated in some important sense other than that outlined. (shrink)

This programmatic paper is an attempt to connect some worries in the philosophy of language with some traditional views in artificial intelligence. After a short introduction to the notion of context in philosophy (§1), starting from the inventor of mathematical logic, Gottlob Frege, I list three debates in the philosophy of language where the solution is strongly undecided: §2 treats the debate between holism and molecularism; §3 describes the debate on the boundaries between semantics and pragmatics; §4 hints at a (...) solution of the debate between explicit and implicit view of incomplete descriptions. These debates may be considered case studies on what is happening to the notion of context in philosophy in the first two decades of XXI century; they push us to look for a unifying framework in which to frame those worries: I propose to shift the attention towards a representation of the basic abilities required to navigate across contexts (§5). In the conclusion, I use some suggestions from computer sciences as a contribution towards a better definition of what is meant by “pragmatic competence”, strictly connected to the philosophical enterprise (§6).

What is the relationship between the claim that generics articulate psychologically primitive generalizations and the claim that they exhibit a unique form of context sensitivity?

The problem of value disagreement and contextualist, relativist and metalinguistic attempts of solving it are laid out. Although the metalinguistic account seems to be on the right track, it is argued that it does not sufficiently explain why and how disagreements about the meaning of evaluative terms are based on and can be decided by appeal to existing social practices. As a remedy, it is argued that original suggestions from Putnam's 'The Meaning of "Meaning"' ought to be taken seriously. The (...) resulting dual aspect theory of meaning can explain value disagreement in much the same way as it deals with disagreement about general terms. However, the account goes beyond Putnam's by not just defending a version of social externalism, but also defending the thesis that the truth conditional meaning of many evaluative terms is not fixed by experts either and instead constantly contested as part of a normal function of language.
