RÉSUMÉMichael Tye soutient que certains noms sont vagues parce qu'ils réfèrent à des objets vagues. Tye, cependant, ne distingue pas entre référer à un objet vague et référer vaguement. Je suggère, à partir de certaines suppositions, que les noms vagues doivent référer vaguement. Et si les noms vagues doivent référer vaguement, alors l'argument de Tye échoue, puisque des noms qui réfèrent à des objets vagues n'ont pas besoin de référer vaguement. Néanmoins, l'indétermination dans la méta-sémantique de la relation d'être (...) porteur d'un nom peut créer des noms qui réfèrent vaguement. Cette conclusion ne dépend pas de la supposition que les noms ont un contenu descriptif, ni de l'idée que les énoncés d'identitè peuvent être indéterminés quant à leur valeur de vérité. (shrink)

John Burgess has recently argued that Timothy Williamson’s attempts to avoid the objection that his theory of vagueness is based on an untenable metaphysics of content are unsuccessful. Burgess’s arguments are important, and largely correct, but there is a mistake in the discussion of one of the key examples. In this note I provide some alternative examples and use them to repair the mistaken section of the argument.

Some have argued that the vagueness exhibited by geographic names and descriptions such as ‘Albuquerque’, ‘the Outback’, or ‘Mount Everest’ is ultimately ontological: these terms are vague because they refer to vague objects, objects with fuzzy boundaries. I take the opposite stand and hold the view that geographic vagueness is exclusively semantic, or conceptual at large. There is no such thing as a vague mountain. Rather, there are many things where we conceive a mountain to be, (...) each with its precise boundary, and when we say ‘Everest’ we are just being vague as to which thing we are referring to. This paper defends this view against some plausible objections. (shrink)

This paper intends to further the understanding of the formal properties of (higher-order) vagueness by connecting theories of (higher-order) vagueness with more recent work in topology. First, we provide a “translation” of Bobzien's account of columnar higher-order vagueness into the logic of topological spaces. Since columnar vagueness is an essential ingredient of her solution to the Sorites paradox, a central problem of any theory of vagueness comes into contact with the modern mathematical theory of topology. Second, Rumfitt’s recent topological reconstruction (...) of Sainsbury’s theory of prototypically defined concepts is shown to lead to the same class of spaces that characterize Bobzien’s account of columnar vagueness, namely, weakly scattered spaces. Rumfitt calls these spaces polar spaces. They turn out to be closely related to Gärdenfors’ conceptual spaces, which have come to play an ever more important role in cognitive science and related disciplines. Finally, Williamson’s “logic of clarity” is explicated in terms of a generalized topology (“locology”) that can be considered an alternative to standard topology. Arguably, locology has some conceptual advantages over topology with respect to the conceptualization of a boundary and a borderline. Moreover, in Williamson’s logic of clarity, vague concepts with respect to a notion of a locologically inspired notion of a “slim boundary” are (stably) columnar. Thus, Williamson’s logic of clarity also exhibits a certain affinity for columnar vagueness. In sum, a topological perspective is useful for a conceptual elucidation and unification of central aspects of a variety of contemporary accounts of vagueness. (shrink)

This paper proposes an experimental investigation of the use of vague predicates in dynamic sorites. We present the results of two studies in which subjects had to categorize colored squares at the borderline between two color categories (Green vs. Blue, Yellow vs. Orange). Our main aim was to probe for hysteresis in the ordered transitions between the respective colors, namely for the longer persistence of the initial category. Our main finding is a reverse phenomenon of enhanced contrast (i.e. negative (...) hysteresis), present in two different tasks, a comparative task involving two color names, and a yes/no task involving a single color name, but not found in a corresponding color matching task. We propose an optimality-theoretic explanation of this effect in terms of the strict-tolerant framework of Cobreros et al. (J Philos Log 1–39, 2012), in which borderline cases are characterized in a dual manner in terms of overlap between tolerant extensions, and underlap between strict extensions. (shrink)

An argument is offered for this conditional: If our current concept conscious state is sharp rather than vague, and also correct , then common versions of familiar metaphysical theories of consciousness are false--?namely versions of the identity theory, functionalism, and dualism that appeal to complex physical or functional properties in identification, realization, or correlation. Reasons are also given for taking seriously the claim that our current concept conscious state is sharp. The paper ends by surveying the theoretical options left (...) open by the concept's sharpness and the truth of the conditional argued for in the paper. (shrink)

The paper is divided into two parts, each with subsections. In the first part, I shall discuss some matters that have been extensively examined by Kim, namely what the basic types of supervenience are and how they are pairwise logically related; in the course of this discussion, I shall distinguish a weak from a strong notion of global supervenience. In the second part, I shall examine supervenience in a context in which Kim has not: I shall attempt to solve a (...) puzzle that arises when we consider supervenience relations involving vague properties and/or predicates. This is, of course, not a special case of property/predicate supervenience, but the typical one: for virtually all properties/predicates are vague. The two parts of the paper stand independently of each other. Of the discussion in the first part, essentially all that is presupposed in the second is the notion of “world strong supervenience” defined in section 1 of part I. (shrink)

This paper explores the idea that vague predicates like “tall”, “loud” or “expensive” are applied based on a process of analog magnitude representation, whereby magnitudes are represented with noise. I present a probabilistic account of vague judgment, inspired by early remarks from E. Borel on vagueness, and use it to model judgments about borderline cases. The model involves two main components: probabilistic magnitude representation on the one hand, and a notion of subjective criterion. The framework is used to (...) represent judgments of the form “x is clearly tall” versus “x is tall”, as involving a shift of one’s criterion, and then to derive observed patterns of acceptance for borderline contradictions, namely sentences of the form “x is tall and not tall”, relative to the acceptance of their conjuncts.

In this paper we compare different models of vagueness viewed as a specific form of subjective uncertainty in situations of imperfect discrimination. Our focus is on the logic of the operator “clearly” and on the problem of higher-order vagueness. We first examine the consequences of the notion of intransitivity of indiscriminability for higher-order vagueness, and compare several accounts of vagueness as inexact or imprecise knowledge, namely Williamson’s margin for error semantics, Halpern’s two-dimensional semantics, and the system we call Centered semantics. (...) We then propose a semantics of degrees of clarity, inspired from the signal detection theory model, and outline a view of higher-order vagueness in which the notions of subjective clarity and unclarity are handled asymmetrically at higher orders, namely such that the clarity of clarity is compatible with the unclarity of unclarity.

I propose a view that I call "Ersatz Metaphysical Vagueness" according to which the term "perfectly natural" can be semantically vague. As its name suggests, the view mimics traditional metaphysical vagueness without the radical metaphysical underpinnings. In particular, the ersatzer avoids a widely accepted argument schema (advanced by JRG Williams, Ted Sider, Cian Dorr, John Hawthorne and others) according to which, if there is no metaphysical vagueness, F-ness cannot be both perfectly natural and vague.

Sorensen has argued that one can exploit the vagueness of an ordinary predicate like ‘small’ to induce a sort of vagueness in ‘vague’, by constructing a series of predicates of the form ‘n-small’, where x is n- small if and only if x is small or x n. The resulting ‘Sorensen’ed’ predicates present a Sorites case for ‘vague’ ; hence the vagueness of ‘vague’. Hyde argues that this demonstrates that all vague predicates are higher-order vague. (...) Others doubt whether Sorensen’s series really delivers such a result, claiming Hyde’s argument to be either: unsound, because it misidentifies the true source of vagueness in Sorensen’s Sorites ; invalid, because it fails to generalize to all vague predicates ; or circular, because it presupposes the very thing it tries to prove, namely, higher-order vagueness. This paper contributes to the Sorensen-Hyde vs. Tye-Deas-Hull-Varzi debate by clarifying the relations between vague vagueness and higher-order vagueness. I show how claims of higher-order vagueness are derivable from claims of vague vagueness. This is the missing piece needed to complete Hyde’s argument and overcome the objections presented by Deas, Hull, Tye, and Varzi. I then show how Sorensen’s considerations, once properly generalized, pose more far-reaching consequences about the vagueness of ‘vague’ than either defenders or critics of Hyde’s argument have appreciated.

Vagueness: an expression is vague if and only if it is possible that it give rise to a “borderline case.” A borderline case is a situation in which the application of a particular expression to a (name of) a particular object does not generate an expression with a definite TRUTH-VALUE. That is, the piece of language in question neither applies to the object nor fails to apply. Although such a formulation leaves it open what the pieces of language might (...) be (whole sentences, individual words, NAMES or SINGULAR TERMS, PREDICATES or GENERAL TERMS), most discussions have focussed on vague general terms and have considered other types of terms to be non-vague. (Exceptions to this have called attention to the possibility of vague objects, thereby making the designation relation for singular terms be vague). The formulation also leaves open the possible causes for the expression not to have a definite truth value. If this indeterminacy is due to there being insufficient information available to determine applicability or non-applicability of the term (that is, we’re convinced the term either does or doesn’t apply, but we just don’t have enough information to determine which), then this is sometimes called “epistemic vagueness.” It is somewhat misleading to call this vagueness, for unlike true vagueness, this epistemic vagueness disappears if more information is brought into the situation. (‘There are 1.89∞106 stars in the sky’ epistemically vague but is not vague in the generally accepted sense of the term). ‘Vagueness’ may also be used to characterize non-linguistic items such as CONCEPTS, MEMORIES, and OBJECTS ... as well as such semi-linguistic items as STATEMENTS and PROPOSITIONS. Many of the issues involved in discussing the topic of vagueness impinge upon other philosophical topics, such as the existence of TRUTH-VALUE GAPS (declarative sentences which are neither TRUE nor FALSE) and the plausibility of MANY-VALUED LOGIC..

There are some who defend a view of vagueness according to which there are intrinsically vague objects or attributes in reality. Here, in contrast, we defend a view of vagueness as a semantic property of names and predicates. All entities are crisp, on this view, but there are, for each vague name, multiple portions of reality that are equally good candidates for being its referent, and, for each vague predicate, multiple classes of objects that are equally (...) good candidates for being its extension. We provide a new formulation of these ideas in terms of a theory of granular partitions. We show that this theory provides a general framework within which we can understand the relation between vague terms and concepts on the one hand and correlated portions of reality on the other. We also sketch how it might be possible to formulate within this framework a theory of vagueness which dispenses with the notion of truth-value gaps and other artifacts of more familiar approaches.

The paper defends Gareth Evans's argument against vague identity. It appeals to a principle I name the principle of the diversity of the definitely dissimilar to defend the thesis that vague identity statements owe their indeterminacy to vagueness in language.

Vagueness: an expression is vague if and only if it is possible that it give rise to a “borderline case.” A borderline case is a situation in which the application of a particular expression to a (name of) a particular object does not generate an expression with a definite TRUTH-VALUE.

This paper explores the implications of some experimental data for views that identify colors with objective physical properties such as reflectance profiles. Those who reject objectivist views often argue from the existence of intersubjective differences in color categorization ; but objectivists have managed to stand their ground by identifying colors with sets or ranges of reflectances individuated by the ways in which they stimulate the visual system. In the interest of moving the debate forward, I provide a new kind of (...) evidence against objectivism. Results of a psycholinguistic experiment reveal hysteresis and enhanced contrast in ordinary speakers’ applications of vague terms. These dynamical patterns are purely psychological and give rise to intra-subjective variation in subjects’ applications of vague predicates; in particular, in the case of color predicates, nothing in the stimulus configuration or the illuminant undergoes any change, the only variable being the order in which stimuli are judged. I hypothesize that these order effects are necessary if vague words are to be applicable to values on dimensions, like color, that admit of continuous change. To the extent that this hypothesis is correct, it suggests that if colors are the properties named by ordinary color predicates, and ordinary color predicates are vague, and the application of vague predicates exhibits the order effects found in the experiment, colours cannot be physical or otherwise objective in nature.

In this paper I offer a counterexample to the so called vagueness argument against restricted composition. This will be done in the lines of a recent suggestion by Trenton Merricks, namely by challenging the claim that there cannot be a sharp cut-off point in a composition sequence. It will be suggested that causal powers which emerge when composition occurs can serve as an indicator of such sharp cut-off points. The main example will be the case of a heap. It seems (...) that heaps might provide a very plausible counterexample to the vagueness argument if we accept the idea that four grains of sand is the least number required to compose a heap—the case has been supported by W. D. Hart. My purpose here is not to put forward a new theory of composition, I only wish to refute the vagueness argument and point out that we should be wary of arguments of its form. (shrink)

Attempts to give a Logic or Semantics for vague predicates and to defuse the Sorites paradoxes have been largely a failure. We point out yet another problem with these predicates which has not been remarked on before,namely that different people do and must use these predicates in individually different ways. Thus even if there were a semantics for vague predicates, people would not be able to share it. To explain the occurrence nonetheless of these troublesome predicates in language, (...) we propose a different approach based on asking the question, “How do these vague predicates help people to communicate with each other?” We show that in general, even though different people assign different extensions to vague predicates, they usually benefit from receiving information framed in terms of them.

The Lewis-Sider argument from vagueness is one of the most powerful objections against restricted composition. Many have resisted the argument by rejecting its key premise, namely that existence is not vague. In this paper, I argue that this strategy is ineffective as a response to vagueness-based objections against restricted composition. To that end, I formulate a new argument against restricted composition: the argument from determinate vagueness. Unlike the Lewis-Sider argument, my argument doesn’t require accepting that existence is not (...) class='Hi'>vague, but only that it is not vague in a specific way, which, I argue, is entailed by restricted composition. I show that the rejection of this species of vague existence follows from assumptions even friends of vague existence should be happy to accept. (shrink)

Peter Unger's puzzle, the problem of the many, is an argument for the conclusion that we are grossly mistaken about what kinds of objects are in our immediate surroundings. But it is not clear what we should make of Unger's argument. There is an epistemic view which says that the argument shows that we don't know which objects are the referents of singular terms in our language. There is a linguistic view which says that Unger's puzzle shows that ordinary singular (...) terms and count nouns are vague. Finally, there is an ontological view which says that the puzzle shows that there are vague objects. ;The epistemic view offers the simplest solution to the problem of the many, but runs foul of a different problem, the problem of vague reference. The problem of vague reference is that given the presuppositions of the epistemic view there are too many too similar objects that might be the reference of a name such as 'Kilimanjaro' for it to be plausible that the name has a determinate reference. The linguistic view, spelled out in terms of semantic indecision and supervaluation, offers the same solution to the problem of the many and to the problem of vague reference. But it leaves no room for de re beliefs about ordinary material object. The ontological view offers a solution to the problem of the many that avoids the problem of vague reference and the problem of de re beliefs. For these reasons it is preferable to the other two. ;However, ontological vagueness has met strong objections. It has been argued that it is a fallacy of verbalism, that it is inconsistent and that once formulated in a consistent way it is not distinguishable from the linguistic view. These objections can be met, but not without cost. To avoid the charge of being inconsistent, friends of the ontological view have to give up the law of excluded middle. ;A positive account of vague parthood has two parts. First, parthood is not primitive but dependent on other primitive facts. The most important of the primitive facts are about to what kinds objects belong and how objects are casually related. Second, sometimes the primitive facts fail do determine of two objects whether one is part of the other. Given a notion of vague parthood, a notion of vague object can be defined roughly in the following way: An object O is vague if there is an object a such that it is indeterminate whether a is part of O.

The problem of fuzzy boundaries when delineating cortical areas is widely known in human brain mapping and its adjacent subdisciplines . Yet, a conceptual framework for understanding indeterminacy in neuroscience is missing, and there has been no discussion in the philosophy of neuroscience whether indeterminacy poses an issue for good neuroscientific explanations. My paper addresses both these issues by applying philosophical theories of vagueness to three levels of neuroscientific research, namely to cytoarchitectonic studies at the neuron level intra-areal neuronalinteraction measured (...) by the BOLD-signal of functional magnetic resonance imaging and inter-areal connectivity between different cortical areas. The rest of the paper explores how this framework can be extended to mechanistic explanations in neuroscience. I discuss a semantic and an ontic interpretation of vagueness in mechanistic explanations and argue how both become scientifically interesting from the perspective of a philosophy of scientific practice.

This paper presents a novel semantic analysis of unit names and gradable adjectives, inspired by measurement theory (Krantz et al 1971). Based on measurement theory's typology of measures, I claim that different predicates are associated with different types of measures whose special characteristics, together with features of the relations denoted by unit names, explain the puzzling limited distribution of measure phrases.

In this research work I take into account the relation of indistinguishability. This relation seems to be prima facie reflexive, symmetric and transitive; in short, an equivalence relation. However, there are some cases where the relation under consideration fails to be transitive. In this thesis I will discuss two of those cases: vagueness of gradabale adjectives and count nouns, and identity criteria involving perceptual phenomena. My research attempts to answer the following question: how is it possible to communicate and to (...) make meaningful judgments using vague terms and non-transitive identity criteria? This thesis presents an analysis of vagueness and identity criteria that shows that speakers always consider the elements which vague expressions refer to or whose names compose identity statements within a context and from a certain level of precision. I also attempt to provide a formal treatment of vague adjectives and count nouns on the one hand, and of identity criteria on the other. I employ two key concepts in both the treatments: context dependence and granularity. (shrink)

The main focus of this thesis is indeterminate identity and its relations to vague objects and to imprecise designation. Evans's argument concerning indeterminate-identity statements is often regarded as a proof that vague objects cannot exist. In chapter I I try to argue that the argument may be refuted by vague objects theorists. In chapter II I present various accounts of what indeterminate identity between objects may consist in and three different characteristics of it. I argue that there (...) are objects whose identity is indeterminate and that such indeterminacy is ontic in the sense that it concerns individuation and spatio-temporal boundaries of objects. I also formulate the argument showing that terms designating indeterminately identical objects cannot be precise designators. Chapter III is devoted to problems concerning vagueness and identity-over-time. The indeterminate answer to the questions concerning diachronic identity in puzzling cases can be regarded as the correct response by both endurantists and perdurantists. However, while for perdurantists the whole vagueness of persistence conditions is a conceptual matter, for endurantists it deserves the name of "ontic vagueness". Chapter IV focuses on questions concerning vagueness and identity-at-a-time. I offer a new solution to the problem of the many, according to which in each case in which the problem arises there is - contrary to appearances - only one object present. The problem arises because each such object has many precisifications, which nevertheless have no ontological significance. I also propose a new account of what it takes for an object to be vague. Chapter V deals with indeterminate identity in the domain of quanta. The first part investigates the various problems concerning identity and individuation of quantum particles, whereas the second part is devoted to analysis and critique of E. J. Lowe's example of alleged indeterminate identity-over-time between electrons. (shrink)

[1] We all know that language is vague. The majority of our terms admit borderline cases. We are notoriously unable to resolve the precise number grains required for a portion of sand to fall under the predicate "heap". It might be supposed that blurry boundaries are, at bottom, an ontological phenomenon. Perhaps the indeterminacy of our predicates is inherited from the indeterminacy of the properties they denote. Perhaps objects can also by vague, rendering singularly terms, including proper (...) class='Hi'>names, uncomfortably imprecise. This thesis has been dismissed, challenged, and championed by various philosophers over the course of the century. Undoubtedly the most widely discussed objection to vague ontology comes in the form of a one-page argument devised by Gareth Evans (1978). Although other arguments against vague objects have been proposed,1 Evans' argument has occupied center stage, clarifying and provoking debate. Its impact reconfirms the value of Evans' philosophical legacy. (shrink)

Just about every theorist holds that vague terms are context-sensitive to some extent. What counts as ?tall?, ?rich?, and ?bald? depends on the ambient comparison class, paradigm cases, and/or the like. To take a stock example, a given person might be tall with respect to European entrepreneurs and downright short with respect to professional basketball players. It is also generally agreed that vagueness remains even after comparison class, paradigm cases, etc. are fixed, and so this context sensitivity does not (...) solve the problems with vague terms. In this paper, I briefly sketch the main features of my broadly contextualist account of vagueness, that of the late Ruth Manor, and that of Agustín Rayo, showing how the three accounts relate to, and reinforce, each other, noting a seeming difference. A key item used to articulate my own view is David Lewis's notion of conversational score. This is used to track which borderline cases have been called in the course of a conversation. Manor alludes to Lewis's notion of accommodation, a key aspect of the kinematics of conversation, and Rayo invokes Stalnaker's notion of common ground. I'll show how the conversational score could be employed to develop and extend their views, showing how vague terms, as they construe them, are (or can be) deployed in conversation, consistent with both the underlying indeterminacy of the terms and normal communicative goals. To help develop all three views further, I invoke Craige Roberts's notion of Retrievability, a tool developed to show how definites, such as definite descriptions, singular pronouns, and proper names, are deployed in conversation, in a Lewis-style scorekeeping framework. This, I think, is exactly the right way to understand conversations in what Manor calls non-sorities situations and, to invoke my own view, in sorites situations as well. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Beastly Vagueness in Charles Sanders Peirce and Henry JamesMegan M. QuigleyIn 1878, Charles Sanders Peirce closed the first section of "How to Make our Ideas Clear"—an article that William James later declared a "birth certificate of Pragmatism"—on a strangely anecdotal note.1 Using what would become known as the pragmatic method to demolish the notion of Grand Ideas ("Our idea of anything is our idea of its sensible effects"), Peirce (...) also included a lesson from an "old German story":Many a man has cherished for years some vague shadow of an idea, too meaningless to be positively false; he has nevertheless, passionately loved it, has made it his companion by day and by night, and has given to it his strength and his life, leaving all other occupations for its sake, and in short has lived with it and for it, until it has become, as it were, flesh of his flesh and bone of his bone; and then he has waked up some morning to find it gone, cleaned vanished away like the beautiful Melusina of the fable, and the essence of his life gone with it. I have myself known such a man.(WCSP, p. 261)The story of the fled Melusina (a half-woman, half-serpent who gives birth to monsters) acts ostensibly as a warning against the danger inherent in "vague" ideas. "A vague shadow of an idea" can sap the life-blood out of a young man and, therefore, Peirce asserted, we must strive to be clear. But Peirce's anecdote did more than further his argument; it was an autobiographical aside—so personal, in fact, that he ordered the passage to be deleted in all future printings of his essay.Melusina was not just an allusion to a mythological figure; it was also a reference to the middle name of his wife, Harriet Melusina Fay. Since his schooldays, Peirce's friend and, later, wife, whom he called [End Page 362] "Zina," had been his constant companion and even the scribe for his fervent aspirations. Under the title "Theories of C. S. Peirce, 1854" she had transcribed his ambitious declaration: "My life is built upon a theory: and if this theory turns out false, my life will turn out a failure" (Brent, p. 51). By the mid 1870s, Peirce's theory, "passionately loved... his companion by day and by night," was finally being elucidated in his articles; however, Melusina herself had "cleaned vanished away," after two decades of intimacy, leaving Peirce in Paris to what his friend Henry James described as "a very lonely and dreary existence." Peirce's inclusion of an anecdote about his own loneliness—"I have myself known such a man"—is poignant even as it reveals his anger. Melusina is both a monster and "beautiful," and with her disappearance, Peirce has lost, "the essence of his life." The personal allusion also highlights the anxiety in the young Peirce's writing. What if his theories came to nothing, remained merely vague, and he lost his whole life and his wife to a misguided dedication? And how ironic would that be given that the idea itself aimed to explode the fallacy of grand ideas? Such an irony was not lost on his main companion during the winter of 1875, Henry James.In the following pages I aim to demonstrate that Charles S. Peirce's anxiety acted as a germ for the beast of John Marcher in James's late story, "The Beast in the Jungle." "More than any of Henry James's tales," Paul Lindholdt writes, "'The Beast in the Jungle,' has prompted source studies and psychoanalytic discussions by critics striving to identify" John Marcher.2 Eager to diagnose the relationship between Marcher and May Bartram, critics have sought both autobiographical and literary sources for Marcher's character.3 Strangely, however, no one has noted the connection between Peirce and Marcher, an omission that is especially odd given the critical attention directed at the relationship between the story and pragmatism. Since Richard Hocks's Henry James and Pragmatistic Thought highlighted the pragmatic tendencies of James's story and called Marcher the "anti-pragmatist" hero, "an epitome of William's... (shrink)

This paper deals with the exceptions-tolerance property of generic sentences with indefinite singular and bare plural subjects (IS and BP generics, respectively) and with the way this property is connected to some well-known observations about felicity differences between the two types of generics (e.g. Lawler's 1973, Madrigals are popular vs. #A madrigal is popular). I show that whereas both IS and BP generics tolerate exceptional and contextually irrelevant individuals and situations in a strikingly similar way, which indicates the existence of (...) a basically equivalent tolerance mechanism, there is also a difference between them, unnoticed so far, which concerns the degree to which the properties of the legitimate exceptions can be characterized in advance. Following claims in Greenberg (2003), I argue that both this newly observed difference as well as the traditional felicity differences result from an underlying contrast in the type of ‘non-accidentalness’ expressed by the two types of generic sentences, and more formally, in the accessibility relations that their generic quantifier (Gen) is compatible with. To capture the new difference in tolerance of exceptions, I develop an improved version of the exceptions-tolerance mechanism for generic sentences suggested in Kadmon & Landman (1993), namely, a restriction on the set of individuals and situations quantified by Gen, which is partially vague to two different degrees using supervaluationist methods. The different degrees of vagueness in this restriction are shown to be systematically dependent on the two types of accessibility relations that IS and BP generics are compatible with, which are redefined as precise and vague restrictions on the generic quantification over worlds.

Many theists and atheists believe that God would not permit an evil unless God’s allowing it (or an evil at least as bad) is required for a greater good. In “The Argument from Particular Horrendous Evils” (and elsewhere) Peter van Inwagen has argued against this belief by appealing to his “No Minimum Claim” (NMC), namely, that it is reasonable to believe there is no minimum amount of evil required for God’s purposes. In this paper I distinguish different formulations of NMC, (...) and, by drawing an instructive parallel to traditional sorites paradoxes, refute Jeff Jordan’s criticism that because morally significant suffering is finitelydiminishable, NMC must be false.

Legal concepts and notions are deeply affected by religions, ethics, philosophy and the culture of a particular nation. As Friedman Comparing legal cultures, Dartmouth, Aldershot, 1997, p. 34) highlights, understanding legal culture is a crucial factor as it both affects their translation and interpretation and consequently has an impact on the application of law. This increases in importance, for example, in the context of the principle of mutual trust and recognition of judgments assumed by the European Union as the cornerstone (...) of judicial co-operation in the European Union, which would not be possible without the trust in each other’s justice system and the respect for the different legal systems and traditions of the Member States. In that vein, ‘the Third Space’, where legal concepts and notions of multiple origins meet and where their meanings are negotiated, transformed, translated and integrated into various socio-political and cultural contexts has acquired an immense significance. Although there may be natural similarities between legal professions in the European Union, they could differ quite substantially as they are deeply rooted in the history and societal evolution of a country; therefore, they are generally regulated at a national, not a European level. In light of the above, the author intends to perform an in-depth analysis of key terminology in the field of names of legal professions which exist in the Member States of the European Union. The author focuses on the terms which refer to the legal profession of lawyers as they might pose obstacles in translation and interpretation due to different functions and roles these legal professionals play in their legal systems or due to the lack of their equivalents in other legal systems. The terminology is compared to present similarities and differences in their meaning, particularly putting some emphasis on socio-political and cultural contexts. The research methods encompass the analysis of relevant literature and the terminological analysis of the research material, which includes the information on legal professions provided by particular Member States on the European e-Justice portal and relevant national regulations in that respect. Finally, the author draws the conclusion that a thorough analysis of the functions and roles of a particular legal profession in socio-political and cultural contexts is required before the translation and interpretation of the term is provided as it helps to avoid ambiguity and makes legal communication precise.

I propose understanding CP-law statements as statements that assert the existence of vague statistical laws, not by fully specifying the contents of those laws, but by picking them out via a description that is both self-referential and self-locating. I argue that this proposal validates many common assumptions about CP-laws and correctly classifies many examples of putative CP-laws. It does this while avoiding the most serious worries that motivate some philosophers to be skeptical of CP-laws, namely the worry that they (...) lack non-trivial truth conditions and that it is impossible for empirical evidence to disconfirm them.

A vexing puzzle about vagueness, rationality, and evolution runs, in crude abbreviation, as follows: vague language use is demonstrably suboptimal if the goal is efficient, precise and cooperative information transmission; hence rational deliberation or evolutionary selection should, under this assumed goal, eradicate vagueness from language use. Since vagueness is pervasive and entrenched in all human languages, something has to give. In this paper, we focus on this problem in the context of signaling games. We provide an overview of a (...) number of proposed ways in which vagueness may come into the picture in formal models of rational and evolutionary signaling. Most argue that vague signal use is simply the best we can get, given certain factors. Despite the plausibility of the proposals, we argue that a deeper understanding of the benefits of vagueness needs a more ecological perspective, namely one that goes beyond the local optimization of signaling strategies in a homogeneous population. As an example of one possible way to expand upon our current models, we propose two variants of a novel multi-population dynamic of imprecise imitation where, under certain conditions, populations with vague language use dominate over populations with precise language use.

This paper engages with a specific problem concerning the relationship between descriptive and normative claims. Namely, if we understand that descriptive claims frequently contain normative assertions, and vice versa, how then do we interpret the traditionally rigid distinction that is made between the two, as ’Hume’s law’ or Moore’s ’naturalistic fallacy’ argument offered. In particular, Kripke’s interpretation of Wittgenstein’s ’rule-following paradox’ is specially focused upon in order to re-consider the rigid distinction. As such, the paper argues that if descriptive and (...) normative claims are not mutually exclusive, then we need a new framework with which to understand this relationship. In this regard, the paper borrows from concerns with vagueness, particularly using a degree-theoretic approach in terms of subjective probability, in an attempt to graphically figure out these differences. Consequently, the paper tentatively proposes the hyperbola model in which degrees of normativity and degrees of descriptivity could be expressed and measured. It is hoped, as a result, that this tentative proposal will contribute to deepening the debate on vagueness in general. (shrink)

Abstract The paper is concerned with the status of vague predicates. It is argued that they are for the most part ?classifiers?, which are covertly comparatives and name not monadic properties but relations. The Sorites Paradox, it is claimed, is thus defused and a verdict theory of vague predicates is presented. Our practice in using vague words is described and it is contended that in our use of these predicates we always have a permanent possibility of independent (...) demarcation. Wittgenstein's picture of the wall and the swamp is deployed to avoid the Transition Problem and it is argued against Fregeans that we need vague language for the advancement of knowledge and understanding.

Artificial Intelligence (AI) pervades humanity in 2022, and it is notoriously difficult to understand how certain aspects of it work. There is a movement—_Explainable_ Artificial Intelligence (XAI)—to develop new methods for explaining the behaviours of AI systems. We aim to highlight one important philosophical significance of XAI—it has a role to play in the elimination of vagueness. To show this, consider that the use of AI in what has been labeled _surveillance capitalism_ has resulted in humans quickly gaining the capability (...) to identify and classify most of the occasions in which languages are used. We show that the knowability of this information is incompatible with what a certain theory of vagueness—_epistemicism_—says about vagueness. We argue that one way the epistemicist could respond to this threat is to claim that this process brought about the end of vagueness. However, we suggest an alternative interpretation, namely that epistemicism is false, but there is a weaker doctrine we dub _technological epistemicism_, which is the view that vagueness is due to ignorance of linguistic usage, but the ignorance can be overcome. The idea is that knowing more of the relevant data and how to process it enables us to know the semantic values of our words and sentences with higher confidence and precision. Finally, we argue that humans are probably not going to believe what future AI algorithms tell us about the sharp boundaries of our vague words unless the AI involved can be explained in terms understandable by humans. That is, if people are going to accept that AI can tell them about the sharp boundaries of the meanings of their words, then it is going to have to be XAI. (shrink)

Philosophers disagree about whether vagueness requires us to admit truth-value gaps, about whether there is a gap between the objects of which a given vague predicate is true and those of which it is false on an appropriately constructed sorites series for the predicate—a series involving small increments of change in a relevant respect between adjacent elements, but a large increment of change in that respect between the endpoints. There appears, however, to be widespread agreement that there is some (...) sense in which vague predicates are gappy which may be expressed neutrally by saying that on any appropriately constructed sorites series for a given vague predicate there will be a gap between the objects of which the predicate is definitely true and those of which it is definitely false. Taking as primitive the operator ‘it is definitely the case that’, abbreviated as ‘D’, we may stipulate that a predicate F is definitely true (or definitely false) of an object just in case ‘DF (a)’, where a is a name for the object, is true (or false) simpliciter.1 This yields the following conditional formulation of a ‘gap principle’: (DΦ(x) ∧ D¬Φ(y)) → ¬R(x, y). Here ‘Φ’ is to be replaced with a vague predicate, while ‘R’ is to stand for a sorites relation for that predicate: a relation that can be used to construct a sorites series for the predicate—such as the relation of being just one millimetre shorter than for the predicate ‘is tall’. Disagreements about the sense in which it is correct to say that vague predicates are gappy can then be recast as disagreements about how to understand the definitely operator. One might give it, for example, a pragmatic construal such as ‘it would not be misleading to assert that’; or an epistemic construal such as ‘it is known that’ or ‘it is knowable that’; or a semantic construal such as ‘it is true that’.

Although the predominant view is that vagueness is due to our language being imprecise, the alternative idea that objects themselves do not have determinate borders has received an occasional hearing. But what has failed to be appreciated is how this idea can avoid a puzzle Peter Unger named “The Problem of the Many.”[i].

Bertrand russell, In his paper on "vagueness," claims that all language is vague. His first argument is that language is vague because all words-Physical-Object words, Logical words, Proper names, Etc.-Are vague. Or, To state the argument more fully: a word is vague if it is a word the extent of whose application is essentially doubtful; all words have an extent of application that is essentially doubtful; hence all words are vague. There are several difficulties, (...) Most of which result from russell's use of the phrase 'essentially doubtful'. Physical-Object words may be used vaguely. But to say that words may be used vaguely is not the same as saying that they are vague. Similar considerations apply to logical words. Concerning proper names I argue, First, That, Given russell's theory, He cannot consistently maintain that they are vague, And, Second, That the evidence he offers is not evidence for the vagueness of proper names but evidence that we are sometimes in doubt whether or not to give an entity a name. Russell's second argument is that language is a system, And, Since the system is vague, The component parts of the system must be vague. The argument has its difficulties. (shrink)

A tempting solution to problems of semantic vagueness and to the Liar Paradox is an appeal to truth-value gaps. It is tempting to say, for example, that, where Harry is a borderline case of bald, the sentenceHarry is baldis neither true nor false: it is in the ‘gap’ between these two values, and perhaps deserves a third truth-value. Similarly with the Liar Paradox. Consider the following Liar sentence: is false.That is, sentence says of itself that it is false. If we (...) accept the Tarskian schema S is true iff pwhere ‘S’ is a name of a sentence ‘p,’ we are led into paradox. Both the assumption that is true, and the assumption that is false lead us, via, to is true if and only if is false.Given this result, a natural reaction is to place in a ‘gap’ between true and false.

There are two things we must know in order to know what vagueness is. We must know what kinds of things can be vague. Evidently, predicate and sentence types can be vague, but what about tokens of those types? What about statements and other speech acts? What about abstract entities such as properties and propositions? And what about names and the boundaries of physical objects? Then, of course, for each kind of thing that can be vague, (...) we must know in what vagueness for that kind consists. Needless to say, that there are these two questions doesn’t mean that we should try to answer the first before trying to answer the second. (shrink)

Abstract: We propose a view of vagueness as a semantic property of names and predicates. All entities are crisp, on this semantic view, but there are, for each vague name, multiple portions of reality that are equally good candidates for being its referent, and, for each vague predicate, multiple classes of objects that are equally good candidates for being its extension. We provide a new formulation of these ideas in terms of a theory of granular partitions. We (...) show that this theory provides a general framework within which we can understand the relation between vague terms and concepts and the corresponding crisp portions of reality. We also sketch how it might be possible to formulate within this framework a theory of vagueness which dispenses with the notion of truth-value gaps and other artifacts of more familiar approaches. Central to our approach is the idea that judgments about reality involve in every case (1) a separation of reality into foreground and background of attention and (2) the feature of granularity. On this basis we attempt to show that even vague judgments made in naturally occurring contexts are not marked by truth-value indeterminacy. We distinguish, in addition to crisp granular partitions, also vague partitions, and reference partitions, and we explain the role of the latter in the context of judgments that involve vagueness. We conclude by showing how reference partitions provide an effective means by which judging subjects are able to temper the vagueness of their judgments by means of approximations. (shrink)

Analytic philosophers have traditionally held the proper sense of language to be determined in large part by precise descriptions substituted for the vague words and phrases of ordinary usage. These descriptions are usually conceived as lists of abstract attributes. These attributes, it is often assumed, are synthesized by the mind on the occasion of its contact with particular objects. And, once synthesized, they are held to function as the criteria by which the facts of our ordinary experience are recognized (...) and classified in language. Aspects of this attributive theory go back to Locke, if not to Aristotle, but its classic expression is probably Russell’s theory of definite descriptions. Since the tendency of this theory is to substitute everywhere complex expressions for simpler ones, the simplest parts of speech, i.e., names, are driven to the vanishing point. It is well known, for example, that Russell considered ordinary names such as ’socrates’ to be abbreviations for descriptions and not really names at all; the only terms of ordinary language he considered to be true names are terms such as ‘this’ and ‘that'.

Theory and Practice; Precision and Vagueness. There has long been a conflict between the theory and the practice of scientific naming. The theory expressed both by working scientists and by philosophers has almost always been that precision is an essential part of the scientific attitude and of the procedures and results of science. Theoretically, metaphors have been scorned as belonging to poetry or to philosophy rather than to science. In scientific practice, however, vagueness and metaphor are constantly present; and they (...) are particularly evident at the advancing frontiers of any science, whether mathematical, natural, or social.

This paper presents a novel semantic analysis of unit names and gradable adjectives, inspired by measurement theory (Krantz et al 1971). Based on measurement theory's typology of measures, I claim that different predicates are associated with different types of measures whose special characteristics, together with features of the relations denoted by unit names, explain the puzzling limited distribution of measure phrases.

Spirituality is a highly contested concept. Within the nursing literature, there are a huge range and diversity of definitions, some of which appear coherent whereas others seem quite disparate and unconnected. This vagueness within the nursing literature has led some to suggest that spirituality is so diverse as to be meaningless. Are the critics correct in asserting that the vagueness that surrounds spirituality invalidates it as a significant aspect of care? We think not. It is in fact the vagueness of (...) the concept that is its strength and value. In this paper, we offer a critique of the general apologetic that surrounds the use of the language of spirituality in nursing. With the critics, we agree that the term ‘spirituality’ is used in endlessly different and loose ways. Similarly, we agree that these varied definitions may not refer to constant essences or objects within people or in the world. However, we fundamentally disagree that this makes spirituality irrelevant or of little practical utility. Quite the opposite; properly understood, the vagueness and lack of clarity around the term spirituality is actually a strength that has powerful political, social, and clinical implications. We develop an understanding of spirituality as a way of naming absences and recognizing gaps in healthcare provision as well as a prophetic challenge to some of the ways in which we practise health care within a secular and sometimes secularizing context such as the National Health Service.

This paper illuminates the explanatory role of vagueness und species membership against the background of scientific developments in recent stem cell research. With the help of the Neo-Aristotelian concept of “life form naturalism” ontologically vague entities such as stem cells, all above induced pluripotent stem cells, could be described as necessary constituents for the correct sorting and naming of natural processes and its bearers. Furthermore this specific assessment allows drawing some important ontological and ethical consequences.
