Vagueness and Indeterminacy, Miscellaneous

Nature is complex, exceedingly so. A repercussion of this “complex world constraint” is that it is, in practice, impossible to connect words to the world in a foolproof manner. In this paper I explore the ways in which the complex world constraint makes vagueness, or more generally imprecision, in language in practice unavoidable, illuminates what vagueness comes to, and guides us to a sensible way of thinking about truth. Along the way we see that the problem of ceteris paribus laws (...) is exactly the problem of vagueness and susceptible to similar treatment. (shrink)

Fine (2017) proposes a new logic of vagueness, CL, that promises to provide both a solution to the sorites paradox and a way to avoid the impossibility result from Fine (2008). The present paper presents a challenge to his new theory of vagueness. I argue that the possibility theorem stated in Fine (2017), as well as his solution to the sorites paradox, fail in certain reasonable extensions of the language of CL. More specifically, I show that if we extend the (...) language with any negation operator that obeys reductio ad absurdum, we can prove a new impossibility result that makes the kind of indeterminacy that Fine takes to be a hallmark of vagueness impossible. I show that such negation operators can be conservatively added to CL and examine some of the philosophical consequences of this result. Moreover, I demonstrate that we can define a particular negation operator that behaves exactly like intuitionistic negation in a natural and unobjectionable propositionally quantified extension of CL. Since intuitionistic negation obeys reductio, the new impossibility result holds in this propositionally quantified extension of CL. In addition, the sorites paradox resurfaces for the new negation.

This paper asks: Is the quantifier variantist committed to metaphysical vagueness? My investigation of this question goes via a study of vague existence. I’ll argue that the quantifier variantist is committed to vague existence and that the vague existence posited by the variantist requires a puzzling sort of metaphysical vagueness. Specifically, I distinguish between (what I call) positive and negative metaphysical vagueness. Positive metaphysical vagueness is (roughly) the claim that there is vagueness in the world; negative metaphysical vagueness is (roughly) (...) the claim that there is vagueness that is not in our language or thought. I’ll argue that the quantifier variantist’s commitment to vague existence comes with positive metaphysical vagueness -- even if it doesn't require negative metaphysical vagueness. (shrink)

Generic generalisations like ‘Opioids are highly addictive’ are very useful in scientific communication, but they can often be interpreted in many different ways. Although this is not a problem when all interpretations provide the same answer to the question under discussion, a problem arises when a generic generalisation is used to answer a question other than that originally intended. In such cases, some interpretations of the generalisation might answer the question in a way that the original speaker would not endorse. (...) Rather than excising generic generalisations from scientific communication, I recommend that scientific communicators carefully consider the kinds of questions their words might be taken to answer and try to avoid phrasing that might be taken to provide unintended answers.

ABSTRACT The truth-conditions of utterances are often underdetermined by the meaning of the sentence uttered, as suggested by the observation that the same sentence has different intuitive truth-values in different contexts. The intuitive difference is usually explained by assigning different truth-conditions to different utterances. This paper poses a problem for explanations of this kind: These truth-conditions, if they exist, are epistemically inaccessible. I suggest instead that truth-conditional underdetermination is ineliminable and these utterances have no truth-conditions. Intuitive truth-values are explained by (...) the effect that all the most reasonable interpretations have on the common ground: An utterance is intuitively true when it is true on all interpretations that answer the question under discussion.

The consensus among spacetime substantivalists is to respond to Leibniz's classic shift arguments, and their contemporary incarnation in the form of the hole argument, by pruning the allegedly problematic metaphysical possibilities that generate these arguments. Some substantivalists do so by directly appealing to a modal doctrine akin to anti-haecceitism. Other substantivalists do so by appealing to an underlying hyperintensional doctrine that implies some such modal doctrine. My first aim in this paper is to pose a challenge for all extant forms (...) of this consensus position. My second aim is to show what form substantivalism must take in order to uphold the consensus while addressing this challenge. The result is a novel "plenitudinous" substantivalist view, which predicts that certain modal facts about spacetime are vague or indeterminate. I then argue against this view on independent grounds, concluding that substantivalists should reject the consensus position. The paper also discusses the way forward for substantivalists in light of this conclusion. (shrink)

One of the most popular and enduring approaches to indeterminacy phenomena (e.g., vagueness) over the past several decades has been some form or another of supervaluationism. I argue that supervaluationism is inadequate as a model of indeterminacy: There is an entire class of examples of indeterminacy, characterized by a common “branching” structure, that cannot be modeled in the way supervaluationism proposes. I demonstrate my conclusion explicitly with respect to two specific examples—indeterminate personal identity and indeterminate reference—showing how supervaluationism can model (...) neither. Importantly, my arguments apply to both traditional “semantic” and more recent “metaphysical” versions of supervaluationism. (shrink)

How demanding is the virtuous life? Can virtue exist alongside hints of vice? Is it possible to be virtuous within a vicious society? A line of thinking running through Diogenes and the Stoics is that even a hint of corruption is inimical to virtue, that participating in a vicious society makes it impossible for a person to be virtuous. One response to this difficulty is to claim that virtue is a threshold concept, that context sets a threshold for what is (...) considered virtuous. On this way of thinking, what counts as virtuous in one society may be more demanding than what passes for virtuous in another. This response seems plausible when considering that virtue-theoretic terms like `honest' are gradable adjectives. Many gradable adjectives, like `tall' and `expensive,' have contextual thresholds that shift depending on the situation, and so is tenable that virtue-theoretic adjectives might function with contextual thresholds as well. A major difficulty for this response, however, is that virtue terms are absolute gradable adjectives, a variety of gradable adjectives that do not require a contextual threshold. Absolute gradable adjectives instead draw their truth conditions from their maximal degree, suggesting that Diogenes and the Stoics were correct to think that virtue is incompatible with even a small degree of vice.

This paper concerns regret, where regretting is to be understood, roughly, as mourning the loss of a forgone good. My ultimate aim is to add a new dimension to existing debate concerning the internal logic of regret by revealing the significance of certain sorts of cases—including, most interestingly, certain down-to-earth cases involving vague goals—in relation to the possibility of regret in continued endorsement cases. Intuitively, it might seem like, in continued endorsement cases, an agent’s regret must be tied to the (...) idea that the forgone good is no better than the achieved good but is also not fully made up for by the achieved good because the goods are different in kind. But this view is controversial. After describing a challenge to the view, as well as the main features of the debate regarding regret in which it figures, I appeal first to a fanciful case involving a set of ever-better options, and then to a more down-to-earth case involving a vague goal, to develop a defense of the opposing view that, even in continued endorsement cases, mourning the loss of a forgone good need not be tied to the idea that the loss of the good is not fully made up for by the gain of a preferred or incomparable good of a different kind.

I present a new pragmatic theory of loose talk, focussing on the loose use of numbers and measurement expressions. The account explains loose readings as arising from a pragmatic mechanism aimed at restoring relevance to the question under discussion (QUD), appealing to Krifka's notion of a measurement scale. The core motivating observation is that the loose reading of a claim need not be weaker than its literal content, as almost all pragmatic treatments of loose talk have assumed (e.g. Lasersohn). The (...) loosening mechanism described here can be applied to a range of other linguistic phenomena as well. (shrink)

So far, color-naming studies have relied on a rather limited set of color stimuli. Most importantly, stimuli have been largely limited to highly saturated colors. Because of this, little is known about how people categorize less saturated colors and, more generally, about the structure of color categories as they extend across all dimensions of color space. This article presents the results from a large Internet-based color-naming study that involved color stimuli ranging across all available chroma levels in Munsell space. These (...) results help answer such questions as how English speakers name a more complex color set, whether English speakers use so-called basic color terms (BCTs) more frequently for more saturated colors, how they use non-BCTs in comparison with BCTs, whether non-BCTs are highly consensual in less saturated parts of the solid, how deep inside color space basic color categories extend, or how they behave on the chroma dimension.

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.

The current literature on indeterminacy centers around two projects. One concerns the logic of indeterminacy; the other concerns its nature or source. The aim of this paper is to introduce, motivate and go some way toward addressing a new, third project: that of providing what I call a minimal characterization of indeterminacy. An MC, to a first approximation, is a relatively pre-theoretical characterization of indeterminacy that is neutral between the various substantive theories of the nature and logic of indeterminacy. An (...) MC thus captures a generic sense of indeterminacy that, at least in principle, is recognized by all parties to the debate over the phenomenon’s underlying nature and logic. I begin by introducing the concept of an MC and outlining some of the main theoretical virtues of providing an MC. I then establish some desiderata on a suitable MC, and use these desiderata to rule out various initially attractive proposals. In the final part of the paper I sketch the beginnings of my own MC and defend it against objections. (shrink)

Ben-Yami presents Wittgenstein’s explicit criticism of the Platonic identification of an explanation with a definition and the alternative forms of explanation he employed. He then discusses a few predecessors of Wittgenstein’s criticisms and the Fregean background against which he wrote. Next, the idea of family resemblance is introduced, and objections answered. Wittgenstein’s endorsement of vagueness and the indeterminacy of sense are presented, as well as the open texture of concepts. Common misunderstandings are addressed along the way. Wittgenstein’s ideas, as is (...) then shown, have far-reaching implications for knowledge of meaning and the nature of logic, and with them to the nature of the philosophical project and its possible achievements.

A formal result is proved which is used in Juhani Yli-Vakkuri’s ‘Epistemicism and Modality’ to argue that certain two-dimensional possible world models are inadequate for a language with operators for ‘necessarily’, ‘actually’, and ‘definitely’.

In this paper I suggest that, over and above the need to explore and understand the technological newness of computer art works, there is a need to address the aesthetic significance of the changes and effects that such technological newness brings about, considering the whole environmental transaction pertaining to new media, including what they can or do offer and what users do or can do with such offerings, and how this whole package is integrated into our living spaces and activities. (...) I argue that, given the primacy of computer-based interaction in the new-media, the notion of ‘ornamentality’ indicates the ground-floor aesthetics of new-media environments. I locate ornamentality not only in the logically constitutive principles of the new-media (hypertextuality and interactivity) but also in their multiform cultural embodiments (decoration as cultural interface). I utilize Kendall Walton’s theory of ornamentality in order to construe a puzzle pertaining to the ornamental erosion of information in new-media environments. I argue that insofar as we consider new-media to be conduits of ‘real-life’, the excessive density of ornamental devices prevalent in certain new-media environments forces us to conduct our inquiries under conditions of neustic uncertainty, that is, uncertainty concerning the kind of relationship that we, the users, have to the propositional content mediated. I conclude that this puzzle calls our attention to a peculiar interrogatory complexity inherent in any game of knowledge-seeking conducted across the infosphere, which is not restricted to the simplest form of data retrieval, especially in mixed-reality environments and when the knowledge sought is embodied mimetically.

This book investigates context-sensitivity in natural language by examining the meaning and use of a target class of theoretically recalcitrant expressions. These expressions-including epistemic vocabulary, normative and evaluative vocabulary, and vague language -exhibit systematic differences from paradigm context-sensitive expressions in their discourse dynamics and embedding properties. Many researchers have responded by rethinking the nature of linguistic meaning and communication. Drawing on general insights about the role of context in interpretation and collaborative action, Silk develops an improved contextualist theory of CR-expressions (...) within the classical truth-conditional paradigm: Discourse Contextualism. The aim of Discourse Contextualism is to derive the distinctive linguistic behavior of a CR-expression from a particular contextualist interpretation of an independently motivated formal semantics, along with general principles of interpretation and conversation. It is shown how in using CR-expressions, speakers can exploit their mutual grammatical and world knowledge, and general pragmatic reasoning skills, to coordinate their attitudes and negotiate about how the context should evolve. The book focuses primarily on developing a Discourse Contextualist semantics and pragmatics for epistemic modals. The Discourse Contextualist framework is also applied to other categories of epistemic vocabulary, normative and evaluative vocabulary, and vague adjectives. The similarities/differences among these expressions, and among context-sensitive expressions more generally, have been underexplored. The development of Discourse Contextualism in this book sheds light on general features of meaning and communication, and the variety of ways in which context affects and is affected by uses of language. Discourse Contextualism provides a fruitful framework for theorizing about various broader issues in philosophy, linguistics, and cognitive science. (shrink)

It is both amazing and fitting that this huge, jargon-laden (this book really needs a glossary!), heavily academic work has become a best seller in the world of the educated. One has to be dedicated to learn the jargon and then plow through 551 pages of text and 238 pages of notes. Meanwhile, we are told time and again that this is just an outline of what is to come! -/- Though he severely criticizes the excesses of the three movements, (...) this is a deconstructive and New Age Mystical and postmodern interpretation of religion, philosophy and the behavioral sciences from a very liberal,spiritual point of view—i.e., without the worst of decon, pm and NAM jargon, rabid egalitarianism and anti-scientific anti-intellectualism. -/- He analyzes in some detail the various world views of philosophy, psychology, sociology and religion, exposing their fatal reductionistic flaws with (mostly) care and brilliance, but most of the sources he analyzes are of almost no relevance today. They use terminology and concepts that were already outdated when he was researching and writing 20 years ago. One has to slog thru endless pages of jargon -laden discussion of Habermas, Kant, Emerson, Jung et.al. to get to the pearls. -/- You get a terrific sampling of bad writing, confused and outdated ideas and obsolete jargon. -/- If one has a good current education, it is doubly painful to read this book (and most writing on human behavior). Painful because it´s so tortured and confusing and then again when you realized how simple it is with modern psychology and philosophy. The terminology and ideas are horrifically confused and dated (but less so in Wilber´s own analysis than in his sources). -/- This book and most of its sources are would-be psychology texts, though most of the authors did not realize it. It is about human behavior and reasoning-about why we think and act the way we do and how we might change in the future. But (like all such discussion until recently) none of the explanations are really explanations, and so they give no insight into human behavior. Nobody discusses the mental mechanisms involved. It is like describing how a car works by discussing the steering wheel and metal and paint without any knowledge of the engine, fuel or drive train. In fact, like most older ´explanations` of behavior, the texts quoted here and the comments by Wilber are often more interesting for what kinds of things they accept (and omit!) as explanations, and the kind of reasoning they use, than for the actual content. -/- If one is up on philosophy and cognitive and evolutionary psychology, most of this is archaic. Like nearly everyone (scholars and public alike--eg, see my review of Dennett´s Freedom Evolves and other books), he does not understand that the basics of religion and ethics-- in fact all human behavior, are programmed into our genes. A revolution in understanding ourselves was taking place while he was writing his many books and it passed him by. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my article The Logical Structure of Philosophy, Psychology, Mind and Language as Revealed in Wittgenstein and Searle 59p(2016).

What kind of semantics should someone who accepts the epistemicist theory of vagueness defended in Timothy Williamson’s Vagueness (1994) give a definiteness operator? To impose some interesting constraints on acceptable answers to this question, I will assume that the object language also contains a metaphysical necessity operator and a metaphysical actuality operator. I will suggest that the answer is to be found by working within a three-dimensional model theory. I will provide sketches of two ways of extracting an epistemicist semantics (...) from that model theory, one of which I will find to be more plausible than the other. (shrink)

Let the moral question of personal identity be the following: what is the nature of the entities we should focus our prudential concerns and ascriptions of responsibility around? (If indeed we should structure these things around any entities at all.) Let the semantic question of personal identity be the question of what is the nature of the entities that ‘person’ is true of. A naive (in the sense of simple and intuitive) view would have it that the two questions are (...) so intimately connected that the entities we should focus our concerns and ascriptions around are, pretty trivially, the persons. In part, my aim here is to evaluate this naive view. However, I will not actually attempt to give a definite verdict on it. Rather, I will identify the assumptions under which the naive view is true, and discuss how to go about evaluating those assumptions. (shrink)

The Kripke/Wittgenstein paradox and Goodman’s riddle of induction can be construed as problems of multiple redescription, where the relevant sceptical challenge is to provide factual grounds justifying the description we favour. A choice of description or predicate, in turn, is tantamount to the choice of a curve over a set of data, a choice apparently governed by implicitly operating constraints on the relevant space of possibilities. Armed with this analysis of the two paradoxes, several realist solutions of Kripke’s paradox are (...) examined that appeal to dispositions or other non-occurrent properties. It is found that all neglect crucial epistemological issues: the entities typically appealed to are not observational and must be inferred on the basis of observed entities or events; yet, the relevant sceptical challenge concerns precisely the factual basis on which this inference is made and the constraints operating on it. All disposition ascriptions, the thesis goes on to argue, contain elements of idealization. To ward off the danger of vacuity resulting from the fact that any disposition ascription is true under just the right ideal conditions, dispositional theories need to specify limits on legitimate forms of idealization. This is best done by construing disposition ascriptions as forms of (implicit) curve-fitting, I argue, where the “data” is not necessarily numeric, and the “curve” fitted not necessarily graphic. This brings us full circle: Goodman’s and Kripke’s problems are problems concerning curve-fitting, and the solutions for it appeal to entities the postulation of which is the result of curve-fitting. The way to break the circle must come from a methodology governing the idealizations, or inferences to the best idealization, that are a part of curve-fitting. The thesis closes with an argument for why natural science cannot be expected to be of much help in this domain, given the ubiquity of idealization. (shrink)
