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.

_Identity and Discrimination_, originally published in 1990 and the first book by respected philosopher Timothy Williamson, is now reissued and updated with the inclusion of significant new material. Williamson here proposes an original and rigorous theory linking identity, a relation central to metaphysics, and indiscriminability, a relation central to epistemology.__ Updated and reissued edition of Williamson’s first publication, with the inclusion of significant new material Argues for an original cognitive account of the relation between identity and discrimination that has (...) been influential in the philosophy of perception Pioneers the use of epistemic logic to solve puzzles about indiscriminability Develops the application of techniques from mathematical logic to understand issues about identity over time and across possible worlds.

The theorems of the simplest and strongest sensible quantified modal logic include the Barcan Formula and its converse. Both formulas face strong intuitive objections. This paper develops a theory of possibilia to meet those objections.

The paper argues that, although a distinction between a priori and a posteriori knowledge (or justification) can be drawn, it is a superficial one, of little theoretical significance. The point is not that the distinction has borderline cases, for virtually all useful distinctions have such cases. Rather, it is argued by means of an example, the differences even between a clear case of a priori knowledge and a clear case of a posteriori knowledge may be superficial ones. In both cases, (...) experience plays a role that is more than purely enabling but less than strictly evidential. It is also argued that the cases at issue are not special, but typical of a wide range of others, including knowledge of axioms of set theory and of elementary logical truths. Attempts by Quine and others to make all knowledge a posteriori (‘empirical’) are repudiated. The paper ends with a call for a new framework to be developed for analysing the epistemology of cognitive uses of the imagination. (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)

1. What are called ‘intuitions’ in philosophy are just applications of our ordinary capacities for judgement. We think of them as intuitions when a special kind of scepticism about those capacities is salient. 2. Like scepticism about perception, scepticism about judgement pressures us into conceiving our evidence as facts about our internal psychological states: here, facts about our conscious inclinations to make judgements about some topic rather than facts about the topic itself. But the pressure should be resisted, for it (...) rests on bad epistemology: specifically, on an impossible ideal of unproblematically identifiable evidence. 3. Our resistance to scepticism about judgement is not simply epistemic conservativism, for we resist it on behalf of others as well as ourselves. A reason is needed for thinking that beliefs tend to be true. 4. Evolutionary explanations of the tendency assume what they should explain. Explanations that appeal to constraints on the determination of reference are more promising. Davidson’s truth-maximizing principle of charity is examined but rejected. 5. An alternative principle is defended on which the nature of reference is to maximize knowledge rather than truth. It is related to an externalist conception of mind on which knowing is the central mental state. 6. The knowledge-maximizing principle of charity explains why scenarios for scepticism about judgement do not warrant such scepticism, although it does not explain how we know in any particular case. We should face the fact that evidence is always liable to be contested in philosophy, and stop using talk of intuition to disguise this unpleasant truth from ourselves. (shrink)

Recent work on inference to the best explanation has come to an impasse regarding the proper way to coordinate the theoretical virtues in explanatory inference with probabilistic confirmation theory, and in particular with aspects of Bayes's Theorem. I argue that the theoretical virtues are best conceived heuristically and that such a conception gives us the resources to explicate the virtues in terms of ceteris paribus theorems. Contrary to some Bayesians, this is not equivalent to identifying the virtues with likelihoods or (...) priors per se; the virtues may be more accessible epistemically than likelihoods or priors. I then prove a ceteris paribus theorem regarding theoretical consilience, use it to correct a recent application of Reichenbach's common cause principle, and apply it to a test case of scientific reasoning. Explanation and confirmation The heuristic conception of theoretical virtues Abduction and the accessibility of explanatory power Evidential and theoretical consilience A test case: gravitational lensing Conclusion Thus natural science appears completely to lose from sight the large and general questions; but all the more splendid is the success when, groping in the thicket of special questions, we suddenly find a small opening that allows a hitherto undreamt of outlook on the whole.

This paper is a tribute to Delia Graff Fara. It extends her work on failures of meta-rules for validity as truth-preservation under a supervaluationist identification of truth with supertruth. She showed that such failures occur even in languages without special vagueness-related operators, for standards of deductive reasoning as materially rather than purely logically good, depending on a context-dependent background. This paper extends her argument to: quantifier meta-rules like existential elimination; ambiguity; deliberately vague standard mathematical notation. Supervaluationist attempts to qualify the (...) meta-rules impose unreasonable cognitive demands on reasoning and underestimate her challenge. (shrink)

It is not my claim that the ‘L¨ owenheim-Skolem paradox’ is an antinomy in formal logic; but I shall argue that it is an antinomy, or something close to it, in philosophy of language. Moreover, I shall argue that the resolution of the antinomy—the only resolution that I myself can see as making sense—has profound implications for the great metaphysical dispute about realism which has always been the central dispute in the philosophy of language.

A theory of evidential probability is developed from two assumptions:(1) the evidential probability of a proposition is its probability conditional on the total evidence;(2) one's total evidence is one's total knowledge. Evidential probability is distinguished from both subjective and objective probability. Loss as well as gain of evidence is permitted. Evidential probability is embedded within epistemic logic by means of possible worlds semantics for modal logic; this allows a natural theory of higher-order probability to be developed. In particular, it is (...) emphasized that it is sometimes uncertain which propositions are part of one's total evidence; some surprising implications of this fact are drawn out. (shrink)

According to the principle of bivalence, truth and falsity are jointly exhaustive and mutually exclusive options for a statement. It is either true or false, and not both, even in a borderline case. That highly controversial claim is central to the epistemic theory of vagueness, which holds that borderline cases are distinguished by a special kind of obstacle to knowing the truth-value of the statement. But this paper is not a defence of the epistemic theory. If bivalence holds, it presumably (...) does so as a consequence of what truth and falsity separately are. One may therefore expect bivalence to be derivable from a combination of some principles characterizing truth and other principles characterizing falsity. Indeed, such derivations are easily found. Their form will of course depend on the initial characterizations of truth and falsity, and not all such characterizations will permit bivalence to be derived. In this paper we focus on the relation between its derivability and some principles about truth and falsity. We will use borderline cases for vague expressions as primary examples of an urgent..

The ‘limits of markets’ debate broadly concerns the question of when it is (im)permissible to have a market in some good. Markets can be of tremendous benefit to society, but many have felt that certain goods should not be for sale (e.g., sex, kidneys, bombs). Their sale is argued to be corrupting, exploitative, or to express a form of disrespect. InMarkets without Limits, Jason Brennan and Peter Jaworski have recently argued to the contrary: For any good, as long as it (...) is permissible to give it for free, then it is permissible to give it for money. Their thesis has led to a number of engaging objections, and I leverage recent work on the nature of feasibility within political philosophy to offer a new challenge.I argue that feasibility offers a constraint on which markets can be permissibly implemented. Though it may be possible to create a morally acceptable version of an otherwise repugnant market, some of these markets may be infeasible, and so we are not permitted to implement them. After laying out this challenge, I consider several replies. They concern the relevance of feasibility, and whether any markets really are infeasible. This provides an opportunity to explore the dangers of pursuing the infeasible and with markets generally. I conclude by considering what might lead us to pursue these markets despite their infeasibility, or how knowledge of infeasibility may prove useful regardless. (shrink)

The core of Tony Brueckner’s critique in ‘Knowledge, Evidence, and Skepticism according to Williamson’ is his claim in section 5 that my account of perceptual knowledge has an unacceptable consequence. My reply will concentrate on that claim and largely ignore the rest of Brueckner’s interesting discussion, for it is easy to check that the claim is essential to Brueckner’s argument against my analysis of skepticism and evidence. The alleged consequence at issue concerns a case in which Brueckner knows by seeing (...) that his cup is red. According to Brueckner, I am committed to the implausible view that ‘[his] belief of the proposition that [his] cup is red is justified in virtue of [his] belief of the proposition that [his] cup is red!’ Why does he take my account of..

Second-order logic and modal logic are both, separately, major topics of philosophical discussion. Although both have been criticized by Quine and others, increasingly many philosophers find their strictures uncompelling, and regard both branches of logic as valuable resources for the articulation and investigation of significant issues in logical metaphysics and elsewhere. One might therefore expect some combination of the two sorts of logic to constitute a natural and more comprehensive background logic for metaphysics. So it is somewhat surprising to find (...) that philosophical discussion of secondorder modal logic is almost totally absent, despite the pioneering contribution of Barcan. (shrink)

I. An argument is presented for the conclusion that the hypothesis that no one will ever decide a given proposition is intuitionistically inconsistent. II. A distinction between sentences and statements blocks a similar argument for the stronger conclusion that the hypothesis that I have not yet decided a given proposition is intuitionistically inconsistent, but does not block the original argument. III. A distinction between empirical and mathematical negation might block the original argument, and empirical negation might be modelled on Nelson''s (...) strong negation, but only on intuitionistically unacceptable assumptions. IV. Intuitionists may have to accept the original argument, and therefore be committed to a dubious view of time on which there cannot be merely inductive evidence for statements about the infinite future.

ABSTRACTThis essay is a translation of one of Salomon Maimon’s ethical writings, accompanied by a brief introduction. In it, Maimon proposes a correction of the Kantian moral principle of duty, as it is articulated both by Kant’s Groundwork for a Metaphysics of Morals and his Critique of Practical Reason. In particular, Maimon’s essay reveals the influence of Reinhold’s critique of Kant’s moral philosophy, especially regarding the role of incentives behind moral action. It reveals as well Maimon’s commitment to the primacy (...) of the theoretical over the practical, drawn from his reading of Maimonides and Spinoza. The essay, therefore, marks an important moment in the development of Maimon’s assimilation of Kantian philosophy, one often neglected in scholarship on his work. (shrink)

The following analysis demonstrates that G.H. Mead's understanding of human speech is remarkably consistent with today's interdisciplinary field that studies speech as a natural behavior with an evolutionary history. Mead seems to have captured major empirical and theoretical insights more than half a century before the contemporary field began to take shape. In that field the framework known as “Tinbergen's Four Questions,” developed in ecology to study naturally occurring behavior in nonhuman animals, has been an effective organizing framework for research (...) on human speech. It is used in this paper to organize the comparison of Mead with contemporary scholars. The analysis concludes that Mead was, in a sense, “beyond” the Four Questions by recognizing the limitations of reductionist methods in understanding the nature of conscious phenomena, especially language. Mead's socially situated model of the nature of human speech makes him relevant to today's field where some see an undervaluation of the treatment of language as a social process. (shrink)

Dans ses lectures des nombreux récits de l’Évangile de Jean dans lesquels l’évangéliste mentionne Satan, Thomas d’Aquin montre un souci constant de démolir toute notion selon laquelle le premier des anges déchus peut être identifié à un être maléfique suprême, un summum malum, qui pourrait être identifié avec le démiurge malveillant décrit par les penseurs gnostiques tels que Marcion, Valentin, Mani, ou le mouvement médiéval associé à ce dernier, souvent connu sous le nom de Cathares. La principale de ses préoccupations (...) est la réfutation du déterminisme moral qu’il trouve dans leur pensée, qui est particulièrement incompatible avec la liberté donnée à tous par Dieu pour recevoir la filiation divine, liberté qu’il retrouve tout au long de l’Évangile de Jean.

This paper is a response to “Inferential Evidence” by Jeffrey Dunn, in which he argues that my account of evidence is internally inconsistent, and that any form of Bayesian epistemology excludes evidence gained by inductive inference (which my account allows). In response, I show how the alleged inconsistency dissolves once the process of gaining evidence by inductive inference is fully articulated into the relevant stages, with due attention to the potential role of recognitional capacities.

This brief annotated bibliography is intended to help students get started with their research. It is not a substitute for personal investigation of the literature, and it is not a comprehensive bibliography on the subject. For those just beginning to study Bayesian reasoning, I suggest the starred items as good places to start your reading.

We report the results of an experiment designed to determine the effects of psychological proximity—proxied by awareness of pain and friendship—on moral reasoning. Our study tests the hypotheses that a moral agent’s emphasis on justice decreases with proximity, while his/her emphasis on care increases. Our study further examines how personality, gender, and managerial status affect the importance of care and justice in moral reasoning. We find support for the main hypotheses. We also find that care should be split into two (...) components, one related to protection and the other to the preservation of relationships. Although gender does not affect moral reasoning directly, we find that it does so indirectly via personality, controlling for age, professional status, and professional background. We do not find a significant effect of managerial status on ethics of justice, but do find that holding a managerial position has a negative impact on ethics of care. Regarding personality, we detect significant positive effects of conscientiousness on ethics of justice and of neuroticism on ethics of care. (shrink)

Gerald Dworkin has argued that it is inconsistent with the proper ends of medicine for a physician to participate in an execution by lethal injection. He does this by proposing a principle by which we are to judge whether an action is consistent with the proper ends of medicine. I argue: (a) that this principle, if valid, does not show that it is inconsistent with the proper ends of medicine for a physician to participate in an execution by lethal injection; (...) and (b) that this principle is not valid, and this is because it mistakenly views the promotion of patient autonomy as one of the proper ends of medicine. Rather, I propose, we should view respect for a patient's autonomy as a constraint on the pursuit of the proper ends of medicine, rather than as one of the proper ends itself. With this revised understanding of the proper ends of medicine, we can conclude that it is inconsistent with the proper ends of medicine for a physician to participate in an execution by lethal injection.

The Communist Party USA's reputation for being in the forefront of the fight against African American oppression was forged in the 1930s as the result of the adoption of the Communist International's position that African Americans were an oppressed nationality. According to Marxist-Leninist doctrine, this entitled African Americans to the right to self-determination in that area of the country where they were a majority (the Black Belt South) and equal social and political rights throughout the country. The organizational internalization of (...) this position was accomplished through numerous articles in the Party's press, which were used as educational tools for the membership. The most sustained organizing work in the South occurred in Alabama with the organizing of the Share Croppers Union (SCU). A study of the Party and the SCU in Alabama during the 1930s helps demonstrate the significance of the self-determination position and its importance in shaping the work of the Party among African Americans.
