In this paper, I defend Rudolf Carnap's Principle of Tolerance from an accusation, due to Michael Friedman, that it is self-defeating by prejudicing any debate towards the logically stronger theory. In particular, Friedman attempts to show that Carnap's reconstruction of the debate between classicists and intuitionists over the foundations of mathematics in his book The Logical Syntax of Language, is biased towards the classical standpoint since the metalanguage he constructs to adjudicate between the rival positions is fully classical. (...) I argue that this criticism is mistaken on two counts: (1) it fails to fully appreciate the freedom with regard to the construction of linguistic frameworks that Carnap intended his Principle to embody, and (2) Friedman's objection underestimates the extent to which the evaluation of a framework is task-relative. I conclude that Tolerance is not self-undermining in the way that Friedman claims it is. While this is a restricted conclusion -- and is not a vindication of Carnap's views on logic and mathematics tout court -- it nonetheless suggests that his tolerant perspective has been dismissed too quickly, even by his supporters.

Many authors show how useful logic can be as a tool for building theories that can account for problems in the philosophy of religion, such as paradoxical assertions. As a consequence, one's philosophy of logic is crucial as well, since it determines which logics, from the set of available and constructible logics, one can use to build a theory. In this paper, we present the relatively recent debate between logical pluralism and monism because the positions in this debate determine which (...) logic(s) can, with justification, be applied to build a theory that addresses problems in the philosophy of religion. We begin by presenting the problem of paradoxical assertions and the debate over logical pluralism that bears on the addressing paradoxical assertions. We then canvass strategies for arguing in favor of logical monism, and pluralism; ultimately, we conclude that the Western tradition has reached a stalemate on this issue. We then turn our attention to the potential for Indian religious traditions to contribute to the debate. We present the five-step-syllogism from Nyāya-Hindu philosophy, the four corners of reasoning from Buddhist philosophy, and the seven-fold theory of predication from Jaina philosophy. The upshot of our presentation is to lay the groundwork for cross-traditional logical debate by identifying the ways in which Indian discussions of debate and dialogue relate to modern approaches to logic and the philosophy of logic.

In broadest terms, this thesis is concerned to answer the question of whether the view that arithmetic is analytic can be maintained consistently. Lest there be much suspense, I will conclude that it can. Those who disagree claim that accounts which defend the analyticity of arithmetic are either unable to give a satisfactory account of the foundations of mathematics due to the incompleteness theorems, or, if steps are taken to mitigate incompleteness, then the view loses the ability to account for (...) the applicability of mathematics in the sciences. I will show that this criticism is not successful against every view whereby arithmetic is analytic by showing that the brand of "conventionalism" about mathematics that Rudolf Carnap advocated in the 1930s, especially in Logical Syntax of Language, does not suffer from these difficulties. There, Carnap develops an account of logic and mathematics that ensures the analyticity of both. It is based on his famous "Principle of Tolerance", and so the major focus of this thesis will to defend this principle from certain criticisms that have arisen in the 80 years since the book was published. I claim that these criticisms all share certain misunderstandings of the principle, and, because my diagnosis of the critiques is that they misunderstand Carnap, the defense I will give is of a primarily historical and exegetical nature. Again speaking broadly, the defense will be split into two parts: one primarily historical and the other argumentative. The historical section concerns the development of Carnap's views on logic and mathematics, from their beginnings in Frege's lectures up through the publication of Logical Syntax. Though this material is well-trod ground, it is necessary background for the second part. In part two we shift gears, and leave aside the historical development of Carnap's views to examine a certain family of critiques of it. We focus on the version due to Kurt Gödel, but also explore four others found in the literature. In the final chapter, I develop a reading of Carnap's Principle - the `wide' reading. It is one whereby there are no antecedent constraints on the construction of linguistic frameworks. I argue that this reading of the principle resolves the purported problems. Though this thesis is not a vindication of Carnap's view of logic and mathematics tout court, it does show that the view has more plausibility than is commonly thought. (shrink)

Is language understanding a special case of social cognition? To help evaluate this view, we can formalize it as the rational speech-act theory: Listeners assume that speakers choose their utterances approximately optimally, and listeners interpret an utterance by using Bayesian inference to “invert” this model of the speaker. We apply this framework to model scalar implicature (“some” implies “not all,” and “N” implies “not more than N”). This model predicts an interaction between the speaker's knowledge state and the listener's interpretation. (...) We test these predictions in two experiments and find good fit between model predictions and human judgments. (shrink)

In this essay, I argue that, all else being equal, theism is more probable than naturalism on the assumption that human beings are able to arrive at a body of moral knowledge that is largely accurate and complete. I put forth this thesis on grounds that, if naturalism is true, the explanation of the content of our moral intuitions terminates either in biological-evolutionary processes or in social conventions adopted for pragmatic reasons; that, if this is so, our moral intuitions were (...) selected for their utility, not their truth; and that, if our moral intuitions were so selected, they are probably false. I defend the argument against three objections: first, that the argument amounts to a generic skeptical challenge; second, that ethical naturalism explains how our moral intuitions could have been selected for their truth; and third, that there is a pre-established harmony between the utility of moral beliefs and their truth-values.

I argue for the viability of one neglected way of developing supervenience-based objections to metaethical non-naturalism. This way goes through a principle known as ‘Hume’s Dictum’, according to which there are no necessary connections between distinct existences. I challenge several objections to the Hume’s Dictum-based argument. In the course of doing so, I formulate and motivate modest and precise versions of Hume’s Dictum, illustrate how arguments employing these principles might proceed, and argue that the Hume’s Dictum argument enjoys some advantages (...) relative to other supervenience-based objections to non-naturalism.

I examine issues in the philosophy of religion at the intersection of what possibilities there are and what a God, as classically conceived in the theistic philosophical tradition, would be able to do. The discussion is centered around arguing for an incompatibility between theism and two principles about possibility and ability, and exploring what theists should say about these incompatibilities. -/- I argue that theism entails that certain kinds and amounts of evil are impossible. This puts theism in conflict with (...) popular principles of modal recombination. However, theists have plausible explanations for the violations of recombination that they posit, and can suitably amend these principles without giving up their usefulness in accounting for what possibilities there are. -/- I also argue that despite the impossibility of these evils, God is able to bring these evils about. This puts theism in conflict with the principle that no one is able to do the impossible. However, theists can give a plausible account of why God is unique in being able to do the impossible, and have distinctive resources to address the arguments in favor of the idea that no one is able to do the impossible. And by denying this principle, theists are able to resolve several otherwise difficult puzzles, including reconciling conflicts between the divine attributes. (shrink)

This book introduces a new approach to the issue of radical scientific revolutions, or "paradigm-shifts," given prominence in the work of Thomas Kuhn. The book articulates a dynamical and historicized version of the conception of scientific a priori principles first developed by the philosopher Immanuel Kant. This approach defends the Enlightenment ideal of scientific objectivity and universality while simultaneously doing justice to the revolutionary changes within the sciences that have since undermined Kant's original defense of this ideal. Through a modified (...) Kantian approach to epistemology and philosophy of science, this book opposes both Quinean naturalistic holism and the post-Kuhnian conceptual relativism that has dominated recent literature in science studies. Focussing on the development of "scientific philosophy" from Kant to Rudolf Carnap, along with the parallel developments taking place in the sciences during the same period, the author articulates a new dynamical conception of relativized a priori principles. This idea applied within the physical sciences aims to show that rational intersubjective consensus is intricately preserved across radical scientific revolutions or "paradigm-shifts and how this is achieved.

Everyone has heard of "the invisible hand," the famous metaphor used by Adam Smith (1723-1790) in The Wealth of Nations. Although he uses the expression only once in the book, it has given rise to controversy that has lasted for over two centuries. -/- The famous expression has been understood, in (at least) two very different ways. In one way by most of academia, and in a very different way by Keynes, Noah Chomsky and more lately by Mark Blaug (...) (in the second edition of The New Palgrave, 2008). -/- In the standard textbook interpretation, it is considered a poetical name for "the price mechanism" and presented as an argument in favor of laisser-faire and free trade. In this paper we recall the less well-known interpretation (of Keynes, Blaug and Chomsky), showing that Smith was more reserved towards laisser-faire than is commonly believed and that by "invisible hand" he did not mean the price mechanism.

There is a very plausible principle linking abilities and possibilities: If S is able to Φ, then it is metaphysically possible that S Φ’s. Jack Spencer recently proposed a class of counterexamples to this principle involving the ability to know certain propositions. I renew an argument against these counterexamples based on the unknowability of Fitch propositions. In doing so, I provide a new argument for the unknowability of Fitch propositions and show that Spencer’s counterexamples are in tension with a principle (...) weaker than the one linking abilities and possibilities.

Abstract: In this essay, I outline and defend a version of the aesthetic argument for the existence of God, according to which theism explains our capacity for subjective aesthetic experience better than its major competitor, naturalism. I argue that naturalism fails to adequately explain the nature and range of our aesthetic experiences, since these are amenable neither to standard Darwinian explanation nor to explanation in terms of more complex sociobiological mechanisms such as sexual selection or between-group selection. I concede that (...) aesthetic experience may be an evolutionary spandrel but argue that the conjunction of this thesis with naturalism is highly improbable given the prevalence of beauty in the natural world. Theism, on the other hand, furnishes a robust personal explanation of aesthetic experience, since on theism God has both good reasons to bring such experiences about and the power to do so. I address an objection to the theistic explanation from broadly negative aesthetic experiences, arguing that God plausibly has many reasons to allow these. I contend that this formulation of the argument is superior to other extant versions, since it does not depend on controversial probability judgments, dubious analogies between natural phenomena and human artefacts, or objectivism about aesthetic values.

This paper explores the editorial influence of Joseph Banks on the Philosophical Transactions—still, at the time of his accession to the Presidency of the Royal Society in 1778, the most prestigious scientific periodical published in English. In particular, it examines how Banks forged, and wielded, personal influence over what went into the Transactions. Nominally, at least, the periodical was under the collective control of the Society's council, with significant statutory safeguards in place to prevent editorship by a presidential clique. Yet (...) this was exactly what Banks was able to speedily create and maintain. In this essay I explore how Banks accomplished this and the pressures it produced, addressing two key questions. First, I examine the social dimension of Banks's management of the Transactions (and what contemporaries thought of it), including particularly the questions of how and to whom access to the periodical was afforded or denied by Banks and his associates; and second, I consider how Banks and the Society dealt with the emerging competitive pressure of new commercial and learned society periodicals. I outline a sphere of scientific sociability partly created by informal processes of communicating, circulating, and evaluating papers developed by Banks and his close associates, and its significance for the Transactions in its engagements with other sites, genres, and conventions of scientific publication.

In this essay, I reply to an influential objection to evolutionary debunking arguments against moral realism. According to this objection, our capacity for autonomous rational reflection allows us to grasp moral truths independently of distorting evolutionary influences, so those influences do not prevent us from having moral knowledge. I argue that rational moral reflection is not, in fact, autonomous from evolutionary influences, since it depends on our evolved, pre-reflective grasp of moral properties. I then consider and reject the suggestion that (...) realists can supply an autonomous foundation for rational moral reflection or do without any such foundation. Next, I address the allegation that my arguments have skeptical implications for rational reflection in non-moral domains. Finally, I conclude with a gesture toward a more promising route for realists who oppose debunking arguments. (shrink)

This book addresses some basic questions about intrinsic value: What is it? What has it? What justifies our beliefs about it? In the first six chapters the author defends the existence of a plurality of intrinsic goods, the thesis of organic unities, the view that some goods are 'higher' than others, and the view that intrinsic value can be explicated in terms of 'fitting' emotional attitudes. The final three chapters explore the justification of our beliefs about intrinsic value, including coherence (...) theories and the idea that some value beliefs are warranted on the basis of emotional experience. Professor Lemos defends the view that some value beliefs enjoy 'modest' a priori justification. The book is intended primarily for professional philosophers and their graduate students working in ethics, value theory and epistemology. (shrink)

While every endpointed interval I in a linear order J is, considered as a linear order in its own right, trivially Muchnik‐reducible to J itself, this fails for Medvedev‐reductions. We construct an extreme example of this: a linear order in which no endpointed interval is Medvedev‐reducible to any other, even allowing parameters, except when the two intervals have finite difference. We also construct a scattered linear order which has many endpointed intervals Medvedev‐incomparable to itself; the only other known construction of (...) such a linear order yields an ordinal of extremely high complexity, whereas this construction produces a low‐level‐arithmetic example. Additionally, the constructions here are “coarse” in the sense that they lift to other uniform reducibility notions in place of Medvedev reducibility itself. (shrink)

I examine two related arguments for the claim that if God is omnipotent, God cannot lack abilities such as the ability to do evil or to act irrationally. Both arguments concern the idea that omnipotence is inconsistent with being dominated with respect to abilities. I raise new issues in the formulation of such dominance principles about ability, and attempt to solve them. I also discuss and reject existing objections to these arguments. I conclude that these arguments are promising but not (...) conclusive, and that important work remains to be done in formulating the relevant dominance principles. (shrink)

The health co-benefits of CO2 mitigation can provide a strong incentive for climate policy through reductions in air pollutant emissions that occur when targeting shared sources. However, reducing air pollutant emissions may also have an important co-harm, as the aerosols they form produce net cooling overall. Nevertheless, aerosol impacts have not been fully incorporated into cost-benefit modeling that estimates how much the world should optimally mitigate. Here we find that when both co-benefits and co-harms are taken fully into account, optimal (...) climate policy results in immediate net benefits globally, overturning previous findings from cost-benefit models that omit these effects. The global health benefits from climate policy could reach trillions of dollars annually, but will importantly depend on the air quality policies that nations adopt independently of climate change. Depending on how society values better health, economically optimal levels of mitigation may be consistent with a target of 2 °C or lower. (shrink)

Jacques Derrida's insistence on submitting politics to the test of undecidability elicits the common accusation that an aporetic form of thought can only end in dubious conclusions concerning the pressing matter of politics and that no normative claims can emerge from a thought of radical undecidability. In this paper, I articulate the structural undecidability (aporia) that constitutes politics according to Derrida, the manner in which this structural undecidability elicits judgments, and the importance for critique of not ignoring it. In particular, (...) this structural undecidability is articulated within the event of foundation of any state or set of social relations by way of a declarative act. In addition, the aporetic structure of the political renders visible the essential relationship between (revealed) religion and politics. Ultimately, due to a necessary reference to an ultimate authority at any event of foundation, the political is always already theologico-political in character. (shrink)

Brock and Glasgow recently introduced a new definition of paradox and argue that this conception of paradox itself leads to paradox, the so-called Paradox Paradox. I show that they beg the questions during the course of their argument, but, more importantly, do so in a philosophically interesting way: it reveals a counterexample to the equivalence between being a logical truth and having a probability of one. This has consequences regarding norms of rationality, undermining the grounds for the Conjunction Fallacy.

In this essay, I address an objection to inference to the best explanation due to Bas C. van Fraassen, according to which explanatory virtues cannot confirm a theory, since they make the theory more informative and thus less likely to be true given the probability axioms. I try to show that van Fraassen’s argument, once made precise, is deductively invalid, and that even an ampliative version of the argument (i) implies, absurdly, that no theory is confirmed by its fit with (...) empirical data; (ii) fails to account for confirmatory closure under deduction; and (iii) falsely presupposes that a theory and its sub-theories can be competing explanations.

Martin Buber: The Life of Dialogue , the first study in any language to provide a complete overview of Buber's thought, remains the definitive guide to the full range of his work and the starting point for all modern Buber scholarship. As well as summarizing Buber's early intellectual development and attitudes - his mysticism, his youthful existentialism, his philosophy of Judaism and religious socialism - it focuses on the two crucial issues of his mature thought: his dialogic or I-Thou philosophy, (...) and his probing of the nature and redemption of evil. As a sensitive, intuitive and perennially fascinating account of one of the twentieth century's great spiritual teachers, and as an influential classic in its own right, Martin Buber: The Life of Dialogue reveals the implications of Buber's thought for theory of knowledge, education, philosophy, myth, history and Judaic and Christian belief. This fully revised and expanded 4th edition includes a new preface from the author, an expanded bibliography incorporating new Buber scholarship, and two new appendices in the form of essays on Buber's influence on Emmanuel Levinas and Mikhail Bakhtin.

This article attempts to think through the logic and distinctiveness of the early Royal Society's position as a metropolitan knowledge community and chartered corporation, and the links between these aspects of its being. Among the knowledge communities of Restoration London it is one of the best known and most studied, but also one of the least typical and in many respects one of the least coherent. It was also quite unlike the chartered corporations of the City of London, exercising almost (...) none of their ordinary functions and being granted very limited power and few responsibilities. I explore the society's imaginative and material engagements with longer-established corporate bodies, institutions and knowledge communities, and show how those encounters repeatedly reshaped the early society's internal organization, outward conduct and self-understanding. Building on fundamental work by Michael Hunter, Adrian Johns, Lisa Jardine and Jim Bennett, and new archival evidence, I examine the importance of the city to the society's foundational rhetoric and the shifting orientation of its search for patronage, the development of its charter, and how it learned to interpret the limits and possibilities of its privileges through its encounters with other chartered bodies, emphasizing the contingent nature of its early development.

In this essay, I defend a mind-body dualism, according to which human minds are immaterial substances that exercise non-redundant causal powers over bodies, against the notorious problem of psychophysical causation. I explicate and reply to three formulations of the problem: (i) the claim that, on dualism, psychophysical causation is inconsistent with physical causal closure, (ii) the claim that psychophysical causation on the dualist view is intolerably mysterious, and (iii) Jaegwon Kim’s claim that dualism fails to account for causal pairings. Ultimately, (...) I conclude that these objections fail and that dualist interactionism is no more problematic or mysterious than physical causation. (shrink)

Logic and humour tend to be mutually exclusive topics. Humour plays off ambiguity, while classical logic falters over it. Formalizing puns is therefore impossible, since puns have ambiguous meanings for their components. However, I will use Independence-Friendly logic to formally encode the multiple meanings within a pun. This will show a general strategy of how to logically represent ambiguity and reveals humour as an untapped source of novel logical structure.

Epistemology or the theory of knowledge is one of the cornerstones of analytic philosophy, and this book provides a clear and accessible introduction to the subject. It discusses some of the main theories of justification, including foundationalism, coherentism, reliabilism, and virtue epistemology. Other topics include the Gettier problem, internalism and externalism, skepticism, the problem of epistemic circularity, the problem of the criterion, a priori knowledge, and naturalized epistemology. Intended primarily for students taking a first class in epistemology, this lucid and (...) well-written text would also provide an excellent introduction for anyone interested in knowing more about this important area of philosophy.
