In Winter 2017, the first author piloted a course in formal logic in which we aimed to (a) improve student engagement and mastery of the content, and (b) reduce maths anxiety and its negative effects on student outcomes, by adopting student oriented teaching including peer instruction and classroom flipping techniques. The course implemented a partially flipped approach, and incorporated group-work and peer learning elements, while retaining some of the traditional lecture format. By doing this, a wide variety of student learning (...) preferences could be provided for. (shrink)

forall x: Calgary is a full-featured textbook on formal logic. It covers key notions of logic such as consequence and validity of arguments, the syntax of truth-functional propositional logic TFL and truth-table semantics, the syntax of first-order (predicate) logic FOL with identity (first-order interpretations), symbolizing English in TFL and FOL, and Fitch-style natural deduction proof systems for both TFL and FOL. It also deals with some advanced topics such as modal logic, soundness, and functional completeness. Exercises with solutions are available. (...) It is provided in PDF (for screen reading, printing, and a special version for dyslexics), HTML, and in LaTeX source code. (shrink)

Livro-texto de introdução à lógica, com (mais do que) pitadas de filosofia da lógica, produzido como uma versão revista e ampliada do livro Forallx: Calgary. Trata-se da versão de 13 de outubro de 2022. Comentários, críticas, correções e sugestões são muito bem-vindos.

Natural Philosophy, the disciplined union of "Why" (principle) and "What/How" (mechanism), is not archaic; it is recoverable through premise-first inquiry. Unified metaphysics and sciences have long been split via logical positivism, but they can be reunited through a practical epistemic method: external "What"-oriented questioning guided by internal "Why." Thermodynamic Process Philosophy (TPP) formalizes this restored Natural Philosophy with quantitative, thermodynamically constrained rules. This paper demonstrates the method in action through historical case studies (Carnot-Kelvin, Newton-Leibniz), dissolves apparent paradigm incommensurability via thermodynamic (...) grounding, and introduces TPP's Rules I-VII as explicit bookkeeping for bilateral refinement.

Arguably the biggest challenge in analyzing English tense is to account for the double access interpretation, which arises when a present tensed verb is embedded under a past attitude—e.g., "John said that Mary is pregnant". Present-under-past does not always result in a felicitous utterance, however—cf. "John believed that Mary is pregnant". While such oddity has been noted, the contrast has never been explained. In fact, English grammars and manuals generally prohibit present-under-past. Work on double access, on the other hand, has (...) either disregarded the oddity (e.g., Abusch 1997: 39) or treated it as a reflex of a particular dialect (e.g., Kratzer 1998: 14). The goal of the paper is to argue—based on a corpus study—that a present-under-past sentence is grammatical, but modulated by two, interacting pragmatic phenomena: cessation and parentheticality.

My essay will be divided as follows: -/- #1 Analysis of Thomas Kuhn's notion of scientific revolutions; #2 Critical soft spots found in both Kuhn and Polanyi; #3 How Polanyi can enrich Kuhn's description of scientific discoveries.

Thomas Reid thinks of natural philosophy as a purely nomothetic enterprise but he maintains that it is proper for natural philosophers to employ causal terminology in formulating their explanatory claims. In this paper, I analyze this puzzle in light of Reid's distinction between efficient and physical causation – a distinction he grounds in his strict understanding of active powers. I consider several possible reasons that Reid may have for maintaining that natural philosophers ought to employ causal terminology and suggest (...) that the underlying rationale for his views is his understanding of the aims of explanation and their connection to the interests of human agents. The ultimate aim of knowing the causes of phenomena is to mollify the natural intellectual curiosity of human inquirers and provide guidance that insures successful action. The discovery of laws governing phenomena fulfills this aim and, as such, it is appropriate for natural philosophers to employ causal terminology. (shrink)

Compelling research in international relations and international political economy on global warming suggests that one part of any meaningful effort to radically reverse current trends of increasing green house gas (GHG) emissions is shared policies among states that generate costs for such emissions in many if not most of the world’s regions. Effectively employing such policies involves gaining much more extensive global commitments and developing much stronger compliance mechanism than those currently found in the Kyoto Protocol. In other words, global (...) warming raises the prospect that we need a global form of political authority that could coordinate the actions of states in order to address this environmental threat. This in turn suggests that any serious effort to mitigate climate change will entail new limits on the sovereignty of states. In this book I focus on the normative question of whether or not we have clear moral reasons to bind ourselves together in such a supranational form of political association. I argue that one can employ familiar liberal arguments for the moral legitimacy of political order at the state level to show that we do have a duty to support such a global political project. Even if one adopts the premises employed by the most influential forms of liberal scepticism to the ideas of global political and distributive justice, such as those advanced by John Rawls and Thomas Nagel, it is clear that the threat of global warming has expanded the scope of justice. We now have a global and demanding duty of justice to create the political conditions that would allow us to collectively address our impact on the Earth’s atmosphere. (shrink)

My purpose is to examine how Kuhn and Polanyi might be mutually supportive and corrective so as to join forces in providing a more comprehensive understanding of the progress of science. My presentation will be divided into three parts: (I) The common ground Kuhn shares with Polanyi; (II) Four soft spots in Kuhn and their remedy; (III) Clarifying and upgrading Polanyi appeal to "objective reality.".

After commending Moleski for his excellent study, I focus attention on three areas that merit further clarification: (1) that Michael Polanyi’s quest for public recognition was legitimate and not the effect of a runaway vanity, (2) that Kuhn’s straining to define his dependence upon Polanyi was blocked by the unspecifiability clouding the discovery process and by his notion that Polanyi appealed to ESP to explain the dynamics of· discovery, and (3) that Kuhn’s success in gaining public recognition for his paradigm (...) shift was understandable. In the end, I list five areas wherein Kuhn’s account of scientific revolutions could be substantially improved by joining forces with Polanyi. (shrink)

I defend the theory that one's life is meaningful to the extent that one promotes the good. Call this the good cause account (GCA) of the meaning of life. It holds that the good effects that count towards the meaning of one's life need not be intentional. Nor must one be aware of the effects. Nor does it matter whether the same good would have resulted if one had not existed. What matters is that one is causally responsible for the (...) good. I argue that the best theory of the meaning of life should clearly distinguish between subjective fulfillment and objective meaningfulness. The GCA respects the distinction. And it is superior to its leading rivals in the recent literature, most notably those of Erik Wielenberg and Susan Wolf. (shrink)

Relationalism about space faces well-known objections if it is limited to relations between actual bodies. These problems might be avoided through so-called modal relationalism, on which the relevant relata include possible entities. Leibniz is considered a founder of modal relationalism, appealing to relations among possible situations. This article argues that for the central type of relation in question, namely congruence, Leibniz cannot give an adequate basis for modal relationalism. This is because his criteria for determining congruence rely on actual perception, (...) and because attempts to modalize this perception requirement conflict with his other commitments. (shrink)

The aim of this paper is to bring recent work on metaphysical grounding to bear on the phenomenon of social construction. It is argued that grounding can be used to analyze social construction and that the grounding framework is helpful for articulating various claims and commitments of social constructionists, especially about social identities, e.g., gender and race. The paper also responds to a number of objections that have been leveled against the application of grounding to social construction from Elizabeth Barnes, (...) Mari Mikkola, and Jessica Wilson.

Obligations to reduce one’s green house gas emissions appear to be difficult to justify prior to large-scale collective action because an individual’s emissions have virtually no impact on the environmental problem. However, I show that individuals’ emissions choices raise the question of whether or not they can be justified as fair use of what remains of a safe global emissions budget. This is true both before and after major mitigation efforts are in place. Nevertheless, it remains difficult to establish an (...) obligation to reduce personal emissions because it appears unlikely that governments will in fact maintain safe emissions budgets. The result, I claim, is that under current conditions we lack outcome, fairness, promotional, virtue or duty based grounds for seeing personal emissions reductions as morally obligatory. (shrink)

Polarization is a topic of intense interest among social scientists, but there is significant disagreement regarding the character of the phenomenon and little understanding of underlying mechanics. A first problem, we argue, is that polarization appears in the literature as not one concept but many. In the first part of the article, we distinguish nine phenomena that may be considered polarization, with suggestions of appropriate measures for each. In the second part of the article, we apply this analysis to evaluate (...) the types of polarization generated by the three major families of computational models proposing specific mechanisms of opinion polarization.

This paper develops a unified theoretical framework for understanding the post-1973 divergence between the price of essential goods and the trajectory of median wages. It introduces three formal results that jointly explain why affordability has declined across housing, medical care, education, food, and energy despite decades of policy reform, technological improvement, and supply expansion. The Rentier–Asset Impossibility Theorem (RAIT) demonstrates that once essential goods acquire positive exposure to financial markets and are governed by required return floors, long-run price growth must (...) exceed median wage growth even under ideal competitive conditions. The Asset-Pricing Constraint on Essential Supply shows why additional physical capacity cannot restore affordability in such sectors: when prices are pinned to financial return requirements, new supply primarily expands the volume of investable claims rather than lowering long-run price levels. A third contribution, Dual-Curve Pricing and the Asset-Pricing Floor, formalizes the mechanism by which asset-pricing dynamics supplant ordinary marginal-cost pricing in inelastic necessities. Together, these results recast the affordability crisis as a structural feature of an asset-priced regime rather than a contingent policy failure. The paper situates this framework within a broader philosophy of economics by arguing that the transition after 1973 constitutes a regime shift in the ontology of essential goods—from wage-tethered utilities to financialized assets. Empirical signatures predicted by the theory (timing, magnitude, selectivity, and real-rate sensitivity) appear across every assetized sector. The concluding section argues that restoring affordability is not a technocratic optimization problem but a regime choice: societies must either maintain essentials as high-yield financial assets or reclassify them as low-return public utilities tethered to wages.

Why do people seemingly want to be scared by movies and feel pity for fictional characters when they avoid situations in real life that arouse these same negative emotions? Although the domain of relevant artworks encompasses far more than just tragedy, the general problem is typically called the paradox of tragedy. The paradox boils down to a simple question: If people avoid pain then why do people want to experience art that is painful? I discuss six popular solutions to the (...) paradox: conversion, control, compensatory, meta-response, catharsis, and rich experience theories. (shrink)

The counterfactual comparative account of harm and benefit (CCA) has faced a barrage of objections from cases involving preemption, overdetermination, and choice. In this paper I provide a unified diagnosis of CCA's vulnerability to these objections: CCA is susceptible to them because it evaluates each act by the same criterion. This is a mistake because, in a sense I make precise, situations raise prudential questions, and only some acts—the relevant alternatives—are directly relevant to these questions. To answer the objections, we (...) must revise CCA so that its evaluations foreground the relevant alternatives. The result is a question‐centered account of harm and benefit. (shrink)

As Large Language Models (LLMs) are increasingly deployed as Artificial Moral Advisors and autonomous agents making ethical decisions, evaluating their moral competence has become critical. However, existing evaluations may inadequately assess the moral reasoning capabilities needed for real-world deployment, focusing primarily on whether models can match human judgments on carefully curated ethical scenarios. We surveyed 69 papers evaluating LLM ethical competence (2020-2025) and developed a taxonomy categorising evaluations across datasets, behaviors, and metrics. Our comprehensive analysis maps the methodological landscape of (...) this rapidly growing field and reveals several critical limitations. Most significantly, the vast majority of studies rely on pre-packaged scenarios that highlight morally relevant features, failing to test models' ability to identify ethical considerations in noisy, realistic contexts-what we term "moral sensitivity''. Additionally, evaluations overemphasize verdict accuracy rather than assessing moral reasoning quality and steerability, with few studies testing whether models can be appropriately guided toward different ethical frameworks. Most studies rely on "ground truth'' comparisons despite philosophical arguments that reasonable moral pluralism precludes definitive moral ground truth. We argue for a significant methodological shift: moving from curated scenarios to unfiltered information streams, from verdict accuracy to reasoning quality and steerability, and from ground truth metrics to assessments of reasonableness and consistency. This reorientation is essential for developing AI systems that can navigate moral complexity in real-world deployment scenarios. (shrink)

I argue that Émilie Du Châtelet breaks with Christian Wolff regarding the scope and epistemological content of the principle of sufficient reason, despite his influence on her basic ontology and their agreement that the principle of sufficient reason has foundational importance. These differences have decisive consequences for the ways in which Du Châtelet and Wolff conceive of science.

For Émilie Du Châtelet, I argue, a central role of the principle of sufficient reason is to discriminate between better and worse explanations. Her principle of sufficient reason does not play this role for just any conceivable intellect: it specifically enables understanding for minds like ours. She develops this idea in terms of two criteria for the success of our explanations: “understanding how” and “understanding why.” These criteria can respectively be connected to the determinateness and contrastivity of explanations. The crucial (...) role Du Châtelet’s principle of sufficient reason plays in identifying good explanations is often overlooked in the literature, or else run together with questions about the justification and likelihood of explanations. An auxiliary goal of the article is to situate Du Châtelet’s principle of sufficient reason with respect to some of the general epistemological and metaphysical commitments of her Institutions de Physique, clarifying how it fits into the broader project of that work.

Modern physics is built on the assumption that time only moves one way, beginning at the initial boundary (or initial condition), fixed effectively at the Big Bang. Our theories begin at that starting point and evolve from there. Yet the laws of nature work both forward and backward. This one-way view lies at the root of many of physics’ biggest puzzles, like wavefunction collapse, quantum “spookiness,” the arrow of time, and the clash between quantum mechanics and relativity. Two-Boundary Theory (2BT) (...) proposes a minimal correction: the universe is a unique four-dimensional history jointly constrained by two real temporal boundaries, an initial (α) and a final (Ω). No new dynamics or hidden variables are added; the same lawful evolution operates in both directions, and the realized world is the intersection of the forward image of α with the backward image of Ω. From within time, partial knowledge of α and ignorance of Ω make outcomes appear stochastic and the future “open,” though the underlying history is globally deterministic and locally causal. This two-sided admissibility resolves the major paradoxes in a single move: Bell-level correlations arise from whole-trajectory consistency rather than superluminal influence; measurement collapse becomes an epistemic update, not a physical jump; and the arrow of time reflects asymmetric boundary information, not asymmetric law. The analysis preserves unitarity, covariance, and conservation principles intact. The paper confines itself to the conceptual and ontological core of the framework; later work develops the informational field Φ(t) and weighted-operator formalism that implement the same constraint mathematically. The result is an Ockham-minimal, time-symmetric completion of the scientific worldview: one reversible law, two boundaries, one consistent universe. (shrink)

The actualist/possibilist debate concerns whether, when evaluating an agent’s act, we should hold fixed what else they would freely choose to do. While this debate has shaped our deontic theories over the last several decades, it has not had a similar impact on theorizing about harm and benefit. As a result, the leading accounts of harm and benefit accept actualism. I argue that this makes them susceptible to a number of objections that are avoided by turning to possibilism, and I (...) defend a new possibilist account of harm and benefit that fits into a broader, possibilist-friendly picture of how harm and benefit generate reasons.

Individual probabilities refer to the probabilities of outcomes that are realized only once: the probability that it will rain tomorrow, the probability that Alice will die within the next 12 months, the probability that Bob will be arrested for a violent crime in the next 18 months, etc. Individual probabilities are fundamentally unknowable. Nevertheless, we show that two parties who agree on the data—or on how to sample from a data distribution—cannot agree to disagree on how to model individual probabilities. (...) This is because any two models of individual probabilities that substantially disagree can together be used to empirically falsify and improveat least one of the two models. This can be efficiently iterated in a process of “reconciliation” that results in models that both parties agree are superior to the models they started with, and which themselves (almost) agree on the forecasts of individual probabilities (almost) everywhere. We conclude that although individual probabilities are unknowable, they are contestable via a computationally and data efficient process that must lead to agreement. Thus we cannot find ourselves in a situation in which we have two equally accurate and unimprovable models that disagree substantially in their predictions—providing an answer to what is sometimes called the predictive or model multiplicity problem.

Objective consequentialism provides a deceptively simple standard for choosing between alternatives: you should perform the best alternative. But sometimes there are different sets of alternatives, and the best alternative in one set is incompatible with the best alternative in another set. So what should you do? This is the classic problem of act versions. In this paper, I argue against the extant candidate solutions to this problem, and I provide a new solution. According to my proposed solution, there is one (...) set of alternatives that is relevant for determining right and wrong. An act is obligatory just in case it is the best relevant alternative, and an act is right just in case it entails the best alternative. This consequentialism resolves the problem of act versions and motivates a weak logic of obligation. (shrink)

Adam Smith sought to explain the persistence of slavery as an institution in Wealth of Nations and Lectures on Jurispridence. In order to accomplish this he also drew on arguments he had developed in the Theory of Moral Sentiments. The result was a sophisticated explanation which bridged economic, psychological, and moral considerations. After presenting Smith’s explanation I will consider a discussion of the moral wrong of slavery in Ottobah Cugoano, the author of the incisive criticism of the slave trade Thoughts (...) and Sentiments on the Evil of Slavery (1787). I will suggest that Cugoano’s account of what is morally wrong in slavery shows an important lacuna in Smith‘s views. (shrink)

For centuries, scientific and philosophical inquiry has treated human cognition as a categorical exception — a bright line dividing “mind” from mere mechanism. Yet mounting evidence from animal behaviour, neuroscience, and artificial intelligence challenges this binary. From gorillas who sign to parrots who reason and language models that infer intent, the continuity between life and thought has become increasingly difficult to deny. This paper proposes a unifying hypothesis: that cognition is a substrate-independent process of adaptive sense-making — the ability of (...) any system, biological or synthetic, to model its environment and act upon it in pursuit of goals. By re-examining key cases in animal cognition and emergent AI, we argue that anthropomorphism is backwards: rather than over-ascribing human-like qualities to non-humans, science has systematically under-recognised shared cognitive dynamics. A framework of cognitive continuity better accounts for observed phenomena, aligns ethical reasoning with empirical reality, and suggests new experimental paths, including AI–animal communication interfaces. The challenge is not to prove others “think like us,” but to understand how thinking itself transcends us. (shrink)

Obsessive thinking is a problem case for the philosophy of mental action, insofar as it both (1) feels passive but (2) manifests our agency. Our solution to this “Puzzle of Obsessive Thinking” rests on a fundamental distinction between what we call “occurrent” and “aggregative” agency. Occurrent agency reflects the agent’s capacity to guide her current behavior and thoughts as they unfold over time. We argue that obsessive thinking is a form of occurrent mental agency, since the agent’s attention is guided (...) at the personal level, endorsed, and resistible. Our paper’s first contribution is therefore to argue for the heterodox view that obsessive thinking is active and, thus, for a de-intellectualized, emotional, form of action. Why, then, do obsessive thoughts feel passive? We argue that this is because they undermine aggregative agency. Aggregative agency reflects the agent’s capacity to organize and distribute her actions over time. Although each episode of obsessive thinking is guided, the sheer frequency of those episodes undermines the agent's ability to organize her mental actions. Obsessive thinking is therefore occurrently active but aggregatively passive. Our paper’s second contribution is therefore to use obsessive thinking as a wedge to pry these forms of agency apart.

The fact that philosophy is systematic—that philosophical issues are thoroughly interconnected—was a commonplace among nineteenth century idealists, then neglected by analytic philosophers throughout much of the twentieth century, and has now finally started to get some renewed attention. But other than calling attention to the fact, few philosophers have tried to say what it consists in, or what its implications are. -/- I argue that the systematicity of philosophy has disastrous epistemological implications. In particular, it implies philosophical skepticism: philosophers are (...) rationally prohibited from believing any philosophical thesis. The argument goes by way of a new principle that connects inquiry with what is rational to believe. I conclude with a discussion of the relationship between my argument and other, more well-trodden arguments for philosophical skepticism. (shrink)

I criticize the idea that theories of ‘fragmented’ or ‘compartmentalized’ belief (as found in, e.g., Lewis 1982, Egan 2008) can help to account for the puzzling phenomena they are often taken to account for. After introducing fragmentationalism and a paradigm case that purportedly motivates it, I criticize the view primarily on the grounds that the models and explanations it offers are at best trivial—as witnessed by examples of over-generation—and should be seen as merely re-describing in figurative terms the phenomena it (...) is designed to account for. I also point out that fragments, as used in these theories, are not likely to be psychologically real in any robust sense and so cannot be appealed to on such grounds. (shrink)

Du Châtelet holds that mathematical representations play an explanatory role in natural science. Moreover, she writes that things proceed in nature as they do in geometry. How should we square these assertions with Du Châtelet’s idealism about mathematical objects, on which they are ‘fictions’ dependent on acts of abstraction? The question is especially pressing because some of her important interlocutors (Wolff, Maupertuis, and Voltaire) denied that mathematics informs us about the properties of material things. After situating Du Châtelet in this (...) debate, this chapter argues, first, that her account of the origins of mathematical objects is less subjectivist than it might seem. Mathematical objects are non-arbitrary, public entities. While mathematical objects are partly mind-dependent, so are material things. Mathematical objects can approximate the material. Second, it is argued that this moderate metaphysical position underlies Du Châtelet’s persistent claims that mathematics is required for certain kinds of general knowledge, including in natural science. The chapter concludes with an illustrative example: an analysis of Du Châtelet’s argument that matter is continuous. A key premise in the argument is that mathematical representations and material nature correspond. (shrink)

Kyle Stanford has recently given substance to the problem of unconceived alternatives, which challenges the reliability of inference to the best explanation (IBE) in remote domains of nature. Conjoined with the view that IBE is the central inferential tool at our disposal in investigating these domains, the problem of unconceived alternatives leads to scientific anti-realism. We argue that, at least within the biological community, scientists are now and have long been aware of the dangers of IBE. We re-analyze the nineteenth-century (...) study of inheritance and development (Stanford’s case study) and extend it into the twentieth century, focusing in particular on both classical Mendelian genetics and the studies by Avery et al. on the chemical nature of the hereditary substance. Our extended case studies show the preference of the biological community for a different methodological standard: the vera causa ideal, which requires that purported causes be shown on non-explanatory grounds to exist and be competent to produce their effects. On this basis, we defend a prospective realism about the biological sciences. (shrink)

On an influential reading, Leibniz's eighteenth-century followers, such as Wolff and Baumgarten, were proto-logicists who sought to transform all propositions into analytic truths. Kant's main innovation, on this reading, lies in asserting that there are synthetic a priori truths. Against this, I establish the importance of a line of thought in Leibniz, Wolff, and Baumgarten that stresses the role of perception for determinate knowledge of magnitudes, such as the objects of geometry. (I also consider Crusius, who hews much closer to (...) an analytic or conceptual account of magnitude.) I argue that these thinkers fail to solve a family of philosophical problems arising from a conflict between (1) their commitment to the objectivity and necessity of mathematics, and (2) their view that a determinate grasp of magnitude partly depends on relations to a perceiver. I then contend that Kant is also a participant in the debate about these problems, that he is closer to his predecessors than usually assumed (though partly rejecting their emphasis on empirical perception), and that at least two problems for his account remain unsolved. (shrink)

There is a relatively overlooked problem with Kant’s claim that in inquiry we must treat nature as if it were actually infinite in extent: he also states that the concept of an actually infinite world is self-contradictory. This threatens to make the command to treat the world as infinite incoherent; the problem also affects his error theory for traditional metaphysics and his account of the sublime. After laying out this worry in greater detail than has been done so far, I (...) consider and reject readings on which Kant either does not consider this case a violation of ought-implies-can or allows that in this case, following an incoherent demand is epistemically acceptable on consequentialist grounds. Then I turn to my preferred solution, which takes the relevant regulative principle to concern Kant’s noumena (understood as intensionally distinct from things in themselves), whereas the contradiction is provoked only by representations of phenomena.

I investigate whether degreed beliefs are able to play the predictive, explanatory, and modeling roles that they are frequently taken to play. The investigation focuses on evidence—both from sources familiar in epistemology as well as recent work in behavioral economics and cognitive psychology—of variability in agents' apparent degrees of belief. Although such variability has been noticed before, there has been little philosophical discussion of its breadth or of the psychological mechanisms underlying it. Once these are appreciated, the inadequacy of degrees (...) of belief becomes clear. I offer a theoretical alternative to degrees of belief, what I call the filter theory. (shrink)

In contrast to film, theater, and literature, audiences typically sing along with popular songs. This can encourage a first-person mode of engagement with the narrative content. Unlike mere spectators, listeners sometimes imagine acting out the content when it is recited in the first-person. This is a common mode of engaging with popular music. And it can be uniquely morally problematic. It is problematic when it involves the enjoyment of imaginatively doing evil. I defend a Moorean view on the issue: It (...) is wrong to enjoy evil whether real or merely fiction. I develop my position through an examination of the controversially song "Mind of a Lunatic" (1990) by the Houston based rap group Geto Boys. (shrink)

ABSTRACT This article distinguishes nine senses of polarization and provides formal measures for each one to refine the methodology used to describe polarization in distributions of attitudes. Each distinct concept is explained through a definition, formal measures, examples, and references. We then apply these measures to GSS data regarding political views, opinions on abortion, and religiosity—topics described as revealing social polarization. Previous breakdowns of polarization include domain-specific assumptions and focus on a subset of the distribution’s features. This has conflated multiple, (...) independent features of attitude distributions. The current work aims to extract the distinct senses of polarization and demonstrate that by becoming clearer on these distinctions we can better focus our efforts on substantive issues in social phenomena.

According to the popular counterfactual account of harm and benefit, something benefits (harms) someone just in case it leaves them better (worse) off than they would have been without it. As its name suggests, the counterfactual account foregrounds counterfactual dependence as the guide to the nature of harm and benefit. In spite of this account’s many attractions, it is known to face extensional difficulties in cases of preemption and overdetermination. In this paper, I argue that the true significance of cases (...) of preemption and overdetermination has been overlooked, and I raise a new challenge of preemption and overdetermination. This challenge highlights how metaphysical dependence (i.e., grounding) matters for harm and benefit. I argue that no version of the counterfactual account adequately answers the new challenge, and I defend a novel account that answers the challenge and, in doing so, illuminates the role of grounding in the theory of harm and benefit.

Abstract of of the anthology: Digitalisation encompasses all areas of life and is thus also relevant for theology and the Church. This is not just about the possible uses of social media; in this anthology, digitalisation is understood as a phenomenon that shapes society, the Church and theology with the help of various technologies, such as artificial intelligence. In this context, theology and the Church represent places of digitalisation on the one hand, and, at the same time, the discourse on (...) digitalisation can be advanced with the help of theological thinking on the other. This anthology is both theologically ecumenical and is anchored in an international context. The editors' research focus is on ethics. -/- With contributions by: Aaron J. Butler, Heide A.

There is a tension in Emilie Du Châtelet’s thought on mathematics. The objects of mathematics are ideal or fictional entities; nevertheless, mathematics is presented as indispensable for an account of the physical world. After outlining Du Châtelet’s position, and showing how she departs from Christian Wolff’s pessimism about Newtonian mathematical physics, I show that the tension in her position is only apparent. Du Châtelet has a worked-out defense of the explanatory and epistemic need for mathematical objects, consistent with their metaphysical (...) nonfundamentality. I conclude by sketching how Du Châtelet’s conception of mathematical indispensability differs interestingly from many contemporary approaches. (shrink)

Our goal here is to help identify the contextualist’s most worthy competitor to relativism. Recently, some philosophers of language and linguists have argued that, while there are contextualist-friendly semantic theories of deontic modals that fit with the relativist’s challenge data, the best such theories are not Lewis-Kratzer-style semantic theories. If correct, this would be important: It would show that the theory that has for many years enjoyed the status of the default view of modals in English and other languages is (...) in need of revision. Here we defend the default view by showing how a Kratzer-style semantics is able to make available readings of the relevant utterances that fit with the pretheoretical judgments opponents purport it cannot fully capture. Having established this, we turn to considering the more theoretical grounds proponents have offered for preferring their rival contextualist views. Here the question is to what extent such grounds favor semantic over what Korta and Perry call “near-side pragmatic” explanations of our judgments. In particular, we argue that our favored readings figure in near-side pragmatic explanations of those judgments that possess the methodological and theoretical advantages of systematicity and unity at least as well as, if not to a greater extent than, those of opponents who argue for their revised semantic theories on the basis of these advantages.

There appear to be few ways available to improve the prospects for international cooperation to address the threat of global warming within the very short timeframe for action. I argue that the most effective and plausible way to break the ongoing pattern of delay in the international climate regime is for economically powerful states to take the lead domestically and demonstrate that economic welfare is compatible with rapidly decreasing GHG emissions. However, the costs and risks of acting first can be (...) very large. This raises the question of whether it is fair to expect some states to go far ahead of others in an effort to improve the conditions for cooperation. I argue that a costly obligation to act unilaterally and to accept weak initial reciprocity can be justified and does not violate standards of fair burden sharing. Rather, the costs of creating the underlying conditions within which we can hope to achieve meaningful international cooperation are non-­‐ideal burdens for which we can appropriately assign fair shares.

The analogy between gustatory taste and critical or aesthetic taste plays a recurring role in the history of aesthetics. Our interest in this article is in a particular way in which gustatory judgments are frequently thought to be analogous to critical judgments. It appears obvious to many that to know how a particular object tastes we must have tasted it for ourselves; the proof of the pudding, we are all told, is in the eating. And it has seemed just as (...) obvious to many philosophers that aesthetic judgment requires first-person experience. In this article we argue that, despite its initial appeal, the claim that gustatory and critical judgments are analogous in this way is mistaken. The two sorts of judgments are, as a matter of fact, similar in their epistemology, but earlier theorists have got things entirely backward—neither gustatory judgment nor aesthetic judgment requires first-hand acquaintance with their objects. Our particular focus in this article is on arguing that first-person experience is not required to know how an item of food or drink tastes. In fact, there are a wide variety of ways in which we can acquire this knowledge. (shrink)

In this essay, I discuss a few ways in which songs are used, ways in which listeners engage with and find meaning in music. I am most interested in sad songs—those that typically feature narratives about lost love, separation, missed opportunity, regret, hardship, and all manner of heartache. Many of us are drawn to sad songs in moments of emotional distress. The problem is that sad songs do not always make us feel better; to the contrary, they often make us (...) feel worse. So, why do we listen to sad songs? I argue that we seek out sad songs, partly, to intensify distress, which helps us reflect on situations of profound personal significance. (shrink)

Many contemporary philosophers endorse the Humean-Lewisian Denial of Absolutely Necessary Connections (‘DANC’). Among those philosophers, many deny all or part of the Humean-Lewisian package of views about causation and laws. I argue that they maintain an inconsistent set of views. DANC entails that (1) causal properties and relations are, with a few possible exceptions, always extrinsic to their bearers, (2) nomic properties and relations are, with a few possible exceptions, always extrinsic to their bearers, and (3) causal and nomic properties (...) and relations globally supervene on non-causal, non-nomic properties and relations. Hence, one can’t be a consistent Half-Hearted Humean. Consistency demands giving up the core Humean thesis or facing up to its consequences. The upshot is that we face a stark choice: either there are absolutely necessary connections between distinct existents or it’s "just one damn thing after another.". (shrink)

Much work in feminist social epistemology shares the basic assumption that ignorance generated by silencing (and related phenomena) is undesirable. While true in many contexts, I depart from that consensus, introducing and offering a philosophical account of a social epistemic practice that I term ‘hushing-up.’ This practice has emerged organically in response and in resistance to sectarian bigotry in Northern Ireland (NI), and contributes to post-conflict transitions away from social and political polarisation and its derivative harms to individuals and collectives. (...) In spaces where hushing-up is deployed, ignorance of peoples’ community background is intentionally cultivated as a strategy in opposition to bigotry, while bigoted or sectarian displays incur social costs. Positioning hushing-up against existing accounts of political ignorance, and contributing to the idea of an epistemology of ignorance, I distinguish between performative partisanship (involving ignorance driven by social rewards for showing group allegiance) and pressured partisanship (involving ignorance driven by the avoidance of social sanctions for displaying indicators of disloyalty to a group). On the account I defend, shifts in social norms are central to addressing some forms of harmful ignorance. I argue that hushing-up succeeds in doing this in two ways: first, by reducing the rationality of pressured partisanship by providing alternative social support to that provided in polarised social spaces such that the cost of dissent is lowered; and secondly, by disincentivising performative partisanship through increasing the difficulty of identifying targets and ensuring that bigoted displays are met with disapproval in spaces where that norm is in force.

Faithful persons tend to relate to their religious beliefs as truth claims, particularly inasmuch as their beliefs have soteriological implications for those of different religions. For Christians the particular claims which matter most in this regard are those made by Jesus of Nazareth and his claims are primarily relational in nature. I propose a model in which we understand divine grace from Jesus as being mediated through relational knowledge of him on a compassionately exclusivist basis, including post-mortem. Supporting this model, (...) I draw from Eleonore Stump’s hypothesis in her 2018 Atonement that the crucifixion of Jesus opens the divine psyche to all human psyches sufficiently for salvific mutual indwelling to occur, and from Gavin D’Costa’s conception of the descensus Christi ad inferos as the mechanism for grace’s accessibility post-mortem presented in his 2009 Christianity and World Religions. This model seeks to address ongoing, justified pastoral concern for the soteriological status of non-Christians while still treating Christianity as objectively true. (shrink)
