According to Timothy Williamson 's epistemic view, vague predicates have precise extensions, we just don't know where their boundaries lie. It is a central challenge to his view to explain why we would be so ignorant, if precise borderlines were really there. He offers a novel argument to show that our insuperable ignorance ``is just what independently justified epistemic principles would lead one to expect''. This paper carefully formulates and critically examines Williamson 's argument. It is shown that (...) the argument does not explain our ignorance, and is not really apt for doing so. Williamson 's unjustified commitment to a controversial and crucial assumption is noted. It is also argued in three different ways that his argument is, in any case, self-defeating – the same principles that drive the argument can be applied to undermine one of its premises. Along the way, Williamson 's unstated commitment to a number of other controversial doctrines comes to light. (shrink)

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

Vagueness provides the first comprehensive examination of a topic of increasing importance in metaphysics and the philosophy of logic and language. Timothy Williamson traces the history of this philosophical problem from discussions of the heap paradox in classical Greece to modern formal approaches such as fuzzy logic. He illustrates the problems with views which have taken the position that standard logic and formal semantics do not apply to vague language, and defends the controversial realistic view that vagueness is a (...) kind of ignorance--that there really is a grain of sand whose removal turns a heap into a non-heap, but we cannot know which one it is.

When I take off my glasses, the world looks blurred. When I put them back on, it looks sharpedged. I do not think that the world really was blurred; I know that what changed was my relation to the distant physical objects ahead, not those objects themselves. I am more inclined to believe that the world really is and was sharp-edged. Is that belief any more reasonable than the belief that the world really is and was blurred? I see more (...) accurately with my glasses on than off, so visual appearances when they are on have some cognitive priority over visual appearances when they are off. If I must choose which kind of visual appearance to take at face value, I will choose the sharp-edged look. But what should I think when I see a mist, which looks very blurred however well I am seeing? Indeed, why choose to take any of the looks at face value? Why not regard all the choices as illegitimate projections of ways of seeing the world onto the world itself? (shrink)

The second volume in the _Blackwell Brown Lectures in Philosophy_, this volume offers an original and provocative take on the nature and methodology of philosophy. Based on public lectures at Brown University, given by the pre-eminent philosopher, Timothy Williamson Rejects the ideology of the 'linguistic turn', the most distinctive trend of 20th century philosophy Explains the method of philosophy as a development from non-philosophical ways of thinking Suggests new ways of understanding what contemporary and past philosophers are doing.

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

The paper clarifies and defends the orthodox view that counterfactual conditionals with impossible antecedents are vacuously true against recent criticisms. It argues that apparent counterexamples to orthodoxy result from uncritical reliance on a fallible heuristic used in the processing of conditionals. A comparison is developed between such counterpossibles and vacuously true universal generalizations.

This chapter presents an overview of the major interpretations of probability followed by an outline of the objective Bayesian interpretation and a discussion of the key challenges it faces. I discuss the ramifications of interpretations of probability and objective Bayesianism for the philosophy of mathematics in general.

Understandably absorbed in technical details, discussion of the semantic paradoxes risks losing sight of broad methodological principles. This chapter sketches a general approach to the comparison of rival logics, and applies it to argue that revision of classical propositional logic has much higher costs than its proponents typically recognize.

A study of the contribution semantics makes to the syntactic patterns of English: an intepretive theory of grammar.

Imagine a philosophy conference in Presocratic Greece. The hot question is: what are things made of? Followers of Thales say that everything is made of water, followers of Anaximenes that everything is made of air, and followers of Heraclitus that everything is made of fire. Nobody is quite clear what these claims mean, and some question whether the founders of the respective schools ever made them. But amongst the groupies there is a buzz about all the recent exciting progress. The (...) mockers and doubters make plenty of noise too. They point out that no resolution of the dispute between the schools is in sight. They diagnose Thales, Anaximenes and Heraclitus as suffering from a tendency to overgeneralize. We can intelligibly ask what bread is made of, or what houses are made of, but to ask what things in general are made of is senseless, some suggest, because the question is posed without any conception of how to verify an answer; language has gone on holiday. Paleo-pragmatists invite everyone to relax, forget their futile pseudo-inquiries and do something useful instead. (shrink)

The philosophical relevance of experimental psychology is hard to dispute. Much more controversial is the so‐called negative program's critique of armchair philosophical methodology, in particular the reliance on ‘intuitions’ about thought experiments. This chapter responds to that critique. It argues that, since the negative program has been forced to extend the category of intuition to ordinary judgments about real‐life cases, the critique is in immediate danger of generating into global scepticism, because all human judgments turn out to depend on intuitions. (...) Recently, some proponents of the negative program have tried to demarcate the target of their critique more narrowly. However, their attempts are still far too indiscriminate, and over‐generate scepticism. Nevertheless, once experimental philosophy has refined its own methodology, it may contribute to the refinement of the methodology of mainstream philosophy, by filtering out the effects of cognitive bias, although it offers no prospect of doing without judgments on real or imaginary cases.

This chapter aims to attempt no more than to make some informal and unsystematic remarks on the transformation of analytic philosophy. It deals with a few sketchy remarks on the historiography of recent analytic philosophy. Writing in 1981, David Lewis described “a reasonable goal for a philosopher” as bringing one’s opinions into stable equilibrium. A natural comparison is between Lewis’s Quinean or at least post‐Quinean methodology and the methodology of Peter Strawson, Quine’s leading opponent from the tradition of ordinary language (...) philosophy. Analytic epistemology provides a good case study of the philosophical application of Gricean pragmatics outside the philosophy of language. On Michael Dummett picture of the history of philosophy, Descartes had made epistemology first philosophy, the engine for the rest of philosophy, and then Frege had replaced epistemology by the philosophy of language as first philosophy. The chapter suggests that philosophy sometimes already uses an abductive methodology and ought to use it more in the future. (shrink)

Two opposing tendencies in the philosophy of language go by the names of ‘referentialism’ and ‘inferentialism’ respectively. In the crudest version of the contrast, the referentialist account of meaning gives centre stage to the referential semantics for a language, which is then used to explain the inference rules for the language, perhaps as those which preserve truth on that semantics (since a referential semantics for a language determines the truth-conditions of its sentences). By contrast, the inferentialist account of meaning gives (...) centre stage to the inference rules for the language, which are then used to explain its referential semantics, perhaps as the semantics on which the rules preserve truth. On pain of circularity, we cannot combine both directions of explanation. (shrink)

Presenting a landmark in linguistics and cognitive science, Ray Jackendoff proposes a new holistic theory of the relation between the sounds, structure, and meaning of language and their relation to mind and brain. Foundations of Language exhibits the most fundamental new thinking in linguistics since Noam Chomsky's Aspects of the Theory of Syntax in 1965—yet is readable, stylish, and accessible to a wide readership. Along the way it provides new insights on the evolution of language, thought, and communication.

Ludwig Wittgenstein is perhaps the greatest philosopher of the twentieth century, and certainly one of the most original in the entire Western tradition. Given the inaccessibility of his work, it is remarkable that he has inspired poems, paintings, films, musical compositions, titles of books -- and even novels. In his splendid biography, Ray Monk has made this very compelling human being come alive in a way that perfectly explains the fascination he has evoked. Wittgenstein's life was one of great moral (...) and spiritual depth. Although his work addresses problems of logic, language, mind, and knowledge, he often described it as having an ethical point, and once said that he "could not help seeing every problem from a religious point of view." In successfully bridging the gap assumed by many to exist between Wittgenstein's life and his work, Monk's biography helps to explain the interest in Wittgenstein's later philosophy on the part of Buddhist scholars.

Experiences of embodied remembering are familiar and diverse. We settle bodily into familiar chairs or find our way easily round familiar rooms. We inhabit our own kitchens or cars or workspaces effectively and comfortably, and feel disrupted when our habitual and accustomed objects or technologies change or break or are not available. Hearing a particular song can viscerally bring back either one conversation long ago, or just the urge to dance. Some people explicitly use their bodies to record, store, or (...) cue memories. Others can move skilfully, without stopping to think, in complex and changing environments thanks to the cumulative expertise accrued in their history of fighting fires, or dancing, or playing hockey. The forms of memory involved in these cases may be distinct, operating at different timescales and levels, and by way of different mechanisms and media, but they often cooperate in the many contexts of our practices of remembering.

Metaphysical modalities are definable from counterfactual conditionals, and the epistemology of the former is a special case of the epistemology of the latter. In particular, the role of conceivability and inconceivability in assessing claims of possibility and impossibility can be explained as a special case of the pervasive role of the imagination in assessing counterfactual conditionals, an account of which is sketched. Thus scepticism about metaphysical modality entails a more far-reaching scepticism about counterfactuals. The account is used to question the (...) significance of the distinction between a priori and a posteriori knowledge. (shrink)

I was not impressed by Dr Geggie's article offering a survey of the attitudes of newly appointed consultants towards research fraud ( Journal of Medical Ethics 2001; 27 :344–6). Indeed, by mixing up categories of misconduct from what is at most “bad behaviour” to the very serious, he is not entirely beyond reproach himself. I remind readers that Dr Geggie suggested that 55.7% of the respondents had observed (from the title) “research fraud”. If the term “research fraud” is to have (...) any meaning, it must be reserved for conduct that consciously and deliberately attempts to impose a fraud on others. The US National Academy of Sciences' report, On Being a Scientist: Responsible Conduct in Research distinguishes clearly between “misallocation of credit, honest errors, and errors caused through negligence” and “deception, making up data or results, changing or misreporting data or results, and plagiarism”. The former are “ethical transgressions... that generally remain internal to the scientific community... dealt with locally through peer review, administrative action, and the system of appointments and evaluations”. The latter “strike at the heart of the values on which science is based”. The White House's Office of Science and Technology Policy reached similar conclusions, restricting research misconduct to “fabrication, falsification and plagarism”. I agree with these assessments. In Dr Geggie's paper, deception would include deliberate falsification of data (category 3 of Dr Geggie's table 1), cheating (4A) and deliberately plagiarising …. (shrink)

Credences are beliefs about evidential probabilities. We give the view an assessment-sensitive formulation, show how it evades the standard objections, and give several arguments in support.

Examining one of the fundamental issues in cognitive psychology: How does our conscious experience come to be the way it is?

Being social creatures in a complex world, we do things together. We act jointly. While cooperation, in its broadest sense, can involve merely getting out of each other’s way, or refusing to deceive other people, it is also essential to human nature that it involves more active forms of collaboration and coordination (Tomasello 2009; Sterelny 2012). We collaborate with others in many ordinary activities which, though at times similar to those of other animals, take unique and diverse cultural and psychological (...) forms in human beings. But we also work closely and interactively with each other in more peculiar and flexible practices which are in distinctive ways both species-specific and culturally and historically contingent: from team sports to shared labour, from committee work to mass demonstrations, from dancing to reminiscing together about old times.

Kant stated that there are three mental faculties: cognition, feeling, and desire. The faculty of feeling has received the least scholarly attention, despite its importance in Kant's broader thought, and this volume of new essays is the first to present multiple perspectives on a number of important questions about it. Why does Kant come to believe that feeling must be described as a separate faculty? What is the relationship between feeling and cognition, on the one hand, and desire, on the (...) other? What is the nature of feeling? What do the most discussed Kantian feelings, such as respect and sublimity, tell us about the nature of feeling for Kant? And what about other important feelings that have been overlooked or mischaracterized by commentators, such as enthusiasm and hope? This collaborative and authoritative volume will appeal to Kant scholars, historians of philosophy, and those working on topics in ethics, aesthetics, and emotions. (shrink)

It is widely assumed that religion is responsible for dictating and guiding moral behavior. This study investigated that claim and its relationship to monetary incentive, self-esteem, and gender within the context of academic dishonesty. A sample of 65 undergraduate students were assessed using a revision of Allport's Religious Orientation Scale and then monitored for cheating on a computerized version of the Graduate Records Exam under different experimental conditions. Self-esteem and monetary incentive were manipulated, and gender was selected to measure their (...) effect on cheating behavior. Results of this study found that: participants’ religious orientation was not related to their tendency to cheat in any way; participants cheated significantly more when receiving monetary incentive for their performance than when they did not; participants with induced low self-esteem cheated significantly more than those with induced high self-esteem; and men cheated more than women at a level that bordered on significance. Academic performance was not found related to academic cheating. Findings are discussed in the context of existing literature. (shrink)

Already hailed as a masterpiece, Foundations of Language offers a brilliant overhaul of the last thirty-five years of research in generative linguistics and related fields. "Few books really deserve the cliché 'this should be read by every researcher in the field'," writes Steven Pinker, author of The Language Instinct, "but Ray Jackendoff's Foundations of Language does." Foundations of Language offers a radically new understanding of how language, the brain, and perception intermesh. The book renews the promise of early generative linguistics: (...) that language can be a valuable entrée into understanding the human mind and brain. The approach is remarkably interdisciplinary. Behind its innovations is Jackendoff's fundamental proposal that the creativity of language derives from multiple parallel generative systems linked by interface components. This shift in basic architecture makes possible a radical reconception of mental grammar and how it is learned. As a consequence, Jackendoff is able to reintegrate linguistics with philosophy of mind, cognitive and developmental psychology, evolutionary biology, neuroscience, and computational linguistics. Among the major topics treated are language processing, the relation of language to perception, the innateness of language, and the evolution of the language capacity, as well as more standard issues in linguistic theory such as the roles of syntax and the lexicon. In addition, Jackendoff offers a sophisticated theory of semantics that incorporates insights from philosophy of language, logic and formal semantics, lexical semantics of various stripes, cognitive grammar, psycholinguistic and neurolinguistic approaches, and the author's own conceptual semantics.

Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

Moore’s sympathies are anti‐realist. As an example of an antirealist account of truth, he gives what he calls “the Wittgensteinian View” of truth for mathematical discourse. In attempting to show how to “sidestep certainly apparently decisive objections” to the Wittgensteinian View, Moore acquiesces in the charge that it makes the consistency of a mathematical theory a matter of stipulation: we adopt a rule “that guarantees the consistency of Peano Arithmetic.” Moore’s main concern is the defensibility of anti‐realist view of philosophical (...) discourse. In “Williamson’s Philosophy of Philosophy”, Paul Horwich defends the idea that the proper business of philosophy is clarification rather than systematic theory‐building. In political philosophy, it would be hard to mount a credible defense of some system of government without considering what effects it causally explains. In terms of Diego Marconi’s clear version of Wittgenstein’s account, it is straightforward to explain why it is no longer a live option for so many philosophers. (shrink)

Discusses the scientific potential represented by intelligent machines and their social implications.

A case in point is Frank Jackson’s talk of “conceptual possibility” and “conceptual necessity.” He writes as if the issue between us is the relative methodological priority for philosophy of conceptual modalities and metaphysical modalities. In addition to the uncritical reliance on conceptual modality, another fallacy is surfacing. Paul Boghossian developed an epistemology of logic based on understanding‐assent links corresponding to fundamental rules of logic. His paradigm was modus ponens: a necessary condition for understanding “if” was supposed to be willingness (...) to assent to inferences by modus ponens involving “if.” Boghossian objects that Simon’s tolerance of assent to gappy statements undermines the presumption that he is assenting to them as true. In Nenad Miscevic paper, such competencies are postulated for the linguistic, spatial‐geometric, mathematical, metaphysical, epistemological, and moral domains. Thus Miscevic auxiliary modularity‐independent characterization offers little help in demarcating a useful category of intuition. (shrink)

This chapter argues that the ordinary cognitive capacity to handle counterfactual conditionals carries with it the cognitive capacity to handle metaphysical modality. It aims to illustrate with examples our cognitive use of counterfactual conditionals, and sketches an epistemology for such conditionals. The chapter explains how they subsume metaphysical modality, and assesses the consequences for the distinction between a priori and a posteriori knowledge. It discusses the relation between metaphysical possibility and the restricted kinds of possibility that seem more relevant to (...) ordinary life. Philosophers’ ascriptions of metaphysical modality are far more deeply rooted in our ordinary cognitive practices than most skeptics about it realize. Many philosophers are more confident in their judgments about more or less realistic thought experiments in epistemology and moral philosophy than about more radically strange ones in metaphysics. Philosophical controversy will naturally make the unclear cases salient. (shrink)

This chapter explores some general aspects of the tension between one’s role as a believer and one’s role as an appraiser of oneself as a believer in philosophy. The proposal is to replace true belief by knowledge in a principle of charity constitutive of content. Knowledge maximization need not make the ascription of knowledge come too cheap. By contrast, Davidson’s principle of charity gives good marks to an interpretation for having Stone Age people assent to many truths of quantum mechanics, (...) if it happens to fit the compositional structure of their language. Perhaps the underlying worries about knowledge maximization can be captured in a more abstract form. A subtler attempt to extract knowledge from Davidson’s principle of charity exploits beliefs that one knows. Knowledge maximization implies that our ancestors had some primitive knowledge as soon as they had some primitive beliefs; it is not as though archaeology suggests otherwise. (shrink)
