This paper is a defense of moral evidentialism, the view that we have a moral obligation to form the doxastic attitude that is best supported by our evidence. I will argue that two popular arguments against moral evidentialism are weak. I will also argue that our commitments to the moral evaluation of actions require us to take doxastic obligations seriously.

We discuss Sharon Ryan’s Deep Rationality Theory of wisdom, defended recently in her “Wisdom, Knowledge and Rationality.” We argue that (a) Ryan’s use of the term “rationality” needs further elaboration; (b) there is a problem with requiring that the wise person possess justified beliefs but not necessarily knowledge; (c) the conditions of DRT are not all necessary; (d) the conditions are not sufficient. At the end of our discussion, we suggest that there may be a problem with (...) the very assumption that an informative, non-circular set of necessary and sufficient conditions of wisdom can be given.

In this article, I discuss a trivialization worry for Hartry Field’s official formulation of the access problem for mathematical realists, which was pointed out by Øystein Linnebo (and has recently been made much of by Justin Clarke-Doane). I argue that various attempted reformulations of the Benacerraf problem fail to block trivialization, but that access worriers can better defend themselves by sticking closer to Hartry Field’s initial informal characterization of the access problem in terms of (something like) general epistemic norms of (...) coincidence avoidance. (shrink)

Since Benacerraf’s ‘What Numbers Could Not Be, ’ there has been a growing interest in mathematical structuralism. An influential form of mathematical structuralism, modal structuralism, uses logical possibility and second order logic to provide paraphrases of mathematical statements which don’t quantify over mathematical objects. These modal structuralist paraphrases are a useful tool for nominalists and realists alike. But their use of second order logic and quantification into the logical possibility operator raises concerns. In this paper, I show that the work (...) of both these elements can be done by a single natural generalization of the logical possibility operator. (shrink)

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

The paper argues that knowledge is not closed under logical inference. The argument proceeds from the openness of evidential support and the dependence of empirical knowledge on evidence, to the conclusion that knowledge is open. Without attempting to provide a full-fledged theory of evidence, we show that on the modest assumption that evidence cannot support both a proposition and its negation, or, alternatively, that information that reduces the probability of a proposition cannot constitute evidence for its truth, the relation of (...) evidential support is not closed under known entailment. Therefore the evidence-for relation is deductively open regardless of whether evidence is probabilistic or not. Given even a weak dependence of empirical knowledge on evidence, we argue that empirical knowledge is also open. On this basis, we also respond to the strongest argument in support of knowledge closure. Finally, we present a number of significant benefits of our position, namely, offering a unified explanation for a range of epistemological puzzles. (shrink)

It’s sometimes suggested that we can (in a sense) settle the truth-value of some statements in the language of number theory by stipulation, adopting either φ or ¬φ as an additional axiom. For example, in Clarke-Doane (2020b) and a series of recent APA presentations, Clarke-Doane suggests that any Σ01 sound expansion of our current arithmetical practice would express a truth. In this paper, I’ll argue that (given a certain popular assumption about the model-theoretic representability of languages like ours) we can’t (...) know ourselves to have any such freedom. (shrink)

In this paper, I will attempt to develop and defend a common form of intuitive resistance to the companions in guilt argument. I will argue that one can reasonably believe there are promising solutions to the access problem for mathematical realism that don’t translate to moral realism. In particular, I will suggest that the structuralist project of accounting for mathematical knowledge in terms of some form of logical knowledge offers significant hope of success while no analogous approach offers such hope (...) for moral realism.

Abstract In his discourses on ‘the lily of the field and the bird of the air,’ Kierkegaard presents faith as the best possible response to our precarious and uncertain condition, and as the ideal way to cope with the insecurities and concerns that his readers will recognize as common features of human existence. Reading these discourses together, we are introduced to the portrait of a potential believer who, like the ‘divinely appointed teachers’—the lily and the bird—succeeds in leading a life (...) that is full of care, but free of worry. Such a portrait, we claim, echoes Kierkegaard’s portrait of the knight of faith in Fear and Trembling . In this essay we suggest that faith, as characterized in the ‘lily and bird’ discourses, is a kind of existential trust that would allow us to overcome worry, while remaining wholeheartedly engaged in the finite realm of our cares and concerns. We claim that Kierkegaard’s goal in these discourses is not to belittle our earthly cares, but to invite us to develop a modified attitude toward all that we are susceptible to worry about.

The idea that knowledge can be extended by inference from what is known seems highly plausible. Yet, as shown by familiar preface paradox and lottery-type cases, the possibility of aggregating uncertainty casts doubt on its tenability. We show that these considerations go much further than previously recognized and significantly restrict the kinds of closure ordinary theories of knowledge can endorse. Meeting the challenge of uncertainty aggregation requires either the restriction of knowledge-extending inferences to single premises, or eliminating epistemic uncertainty in (...) known premises. The first strategy, while effective, retains little of the original idea—conclusions even of modus ponens inferences from known premises are not always known. We then look at the second strategy, inspecting the most elaborate and promising attempt to secure the epistemic role of basic inferences, namely Timothy Williamson’s safety theory of knowledge. We argue that while it indeed has the merit of allowing basic inferences such as modus ponens to extend knowledge, Williamson’s theory faces formidable difficulties. These difficulties, moreover, arise from the very feature responsible for its virtue- the infallibilism of knowledge. (shrink)

Harman and Lewis credit Kripke with having formulated a puzzle that seems to show that knowledge entails dogmatism. The puzzle is widely regarded as having been solved. In this paper we argue that this standard solution, in its various versions, addresses only a limited aspect of the puzzle and holds no promise of fully resolving it. Analyzing this failure and the proper rendering of the puzzle, it is suggested that it poses a significant challenge for the defense of epistemic closure.

Semaglutide, sold under the brand names of Ozempic, Rybelsus and Wegovy, is one of the most popular drugs on the market. Manufactured by Novo Nordisk, semaglutide is the newest in a family of glucagon-like peptide-1 receptor agonists used most commonly to treat type II diabetes. To date, the results of semaglutide for the treatment of type II diabetes have been overwhelmingly positive. It is for the drug’s effects on appetite suppression and weight loss, however, that have led its surge in (...) popularity, with many hailing semaglutide as the new ‘miracle drug for weight loss’. Despite its popularity, both the governmental and popular reception to the drug has largely been mixed. In this paper, we address a range of ethical concerns and argue that while many are legitimate, they do not provide conclusive reason not to prescribe semaglutide for weight loss. (shrink)

Most contemporary political science researchers are advocates of multimethod research, however, the value and proper role of qualitative methodologies, like case study analysis, is disputed. A pluralistic philosophy of science can shed light on this debate. Methodological pluralism is indeed valuable, but does not entail causal pluralism. Pluralism about the goals of science is relevant to the debate and suggests a focus on the difference between evidence for warrant and evidence for use. I propose that case study research provides evidence (...) for use through providing information that bears on the applicability of causal generalizations and risk assessment. (shrink)

This article is not about machine consciousness. It's about our understanding of new technology. An emerging contemporary trend treats large language models (LLMs) as cognitive beings partly because they display high-level linguistic abilities. This is in part because we struggle to conceive of a purely linguistic agent. I flesh out this new typological possibility while suggesting that there are interesting features attributable to LLMs based on their architectures and the kinds of information they can process that help us to see (...) the world through their nodes.

Bilateralism in proof-theoretic semantics, according to which rules are provided for both assertions and denials, has been central to the development of inferentialist theories of meaning over the past few decades. Bilateralists are split, however, as to what this position amounts to, with two different formal approaches to bilateralism corresponding to fundamentally different ways of thinking about the basic notion in terms of which an inferentialist theory is to be cast: normative incoherence or committive consequence. In this paper, I show (...) how these two forms of bilateralism can be brought together in a single framework that has the virtues of both. The resulting framework is uniquely capable of serving as a proof-theoretic basis to carry out an inferentialist semantic theory. (shrink)

In this article, robust evidence is provided showing that an individual’s moral character can contribute to the aesthetic quality of their appearance, as well as being beautiful or ugly itself. It is argued that this evidence supports two main conclusions. First, moral beauty and ugliness reside on the inside, and beauty and ugliness are not perception-dependent as a result; and, second, aesthetic perception is affected by moral information, and thus moral beauty and ugliness are on the outside as well.

This document is a set of notes I took on QFT as a graduate student at the University of Pennsylvania, mainly inspired in lectures by Burt Ovrut, but also working through Peskin and Schroeder (1995), as well as David Tong’s lecture notes available online. They take a slow pedagogical approach to introducing classical field theory, Noether’s theorem, the principles of quantum mechanics, scattering theory, and culminating in the derivation of Feynman diagrams.

What is the nature of the concept beauty? Does it differ fundamentally from nearby concepts such as prettiness? It is argued here that beauty, but not prettiness, is a dual-character concept. Across a number of contexts, it is proposed that beauty has descriptive senses that refer to, inter alia, having intrinsically pleasing appearances, and a normative sense associated with deeply held values. This account is supported across two, pre-registered, studies (N=500) and by drawing on analysis of corpus data. It is (...) suggested that this can help to explain why beauty, unlike prettiness, is thought to be deep in both the sense of being important and in the sense of being less closely tied to sensory surfaces.

Ethical, Legal and Social Aspects (ELSA) originated in the 4thEuropean Research Framework Programme (1994) andresponsible research and innovation (RRI) from the EC researchagenda in 2010. ELSA has received renewed attention inEuropean funding schemes and research. This raises the questionof how these two approaches to social responsibility relate toone another and if there is the possibility to align. There is aneed to evaluate the relationship/overlap between ELSA and RRIbecause there is a possibility that new ELSA research will reinventthe wheel if it (...) does not engage with the body of literaturealready present in RRI research. This provides unneeded extrabureaucracy, reformulations of research agendas, extrainvestment, and an overabundance of frameworks to implement,and ELSA research does not take advantage of the body ofresearch developed in RRI. This paper evaluates how ELSA andRRI diverge, are complementary, and can be aligned. (shrink)

Jc Beall argues that if FDE is logic proper, then there is no logical negation. This claim is largely based on the fact that, in standard proof systems for FDE, there are no stand-alone negation rules that suffice to capture the behavior of negation. In this paper, I show that by adopting a bilateral proof system for FDE, one can maintain that there is a logical negation, it is the very same logical negation that belongs to classical logic, and its (...) basic function is to flip-flop between assertion and denial. After laying out the bilateral proof systems on which this claim is technically based, I develop the conception of assertion and denial on which this claim is philosophically based, responding to a number of objections. I conclude by considering the possibility of a different, so-called "Boolean" negation, in the context of this bilateral framework. (shrink)

This paper examines how professionals (N = 32) working on artificial intelligence (AI) view structural AI ethics challenges like injustices and inequalities beyond individual agents' direct intention and control. This paper answers the research question: What are professionals’ perceptions of the structural challenges of AI (in the agri-food sector)? This empirical paper shows that it is essential to broaden the scope of ethics of AI beyond micro- and meso-levels. While ethics guidelines and AI ethics often focus on the responsibility of (...) designers and the competencies and skills of designers to take this responsibility, our results show that many structural challenges are beyond their reach. This result means that while ethics guidelines and AI ethics frameworks are helpful, there is a risk that they overlook more complicated, nuanced, and intersected structural challenges. In addition, it highlights the need to include diverse stakeholders, such as quadruple helix (QH) participants, in discussions around AI ethics rather than solely focusing on the obligations of AI developers and companies. Overall, this paper demonstrates that addressing structural challenges in AI is challenging and requires an approach that considers four requirements: (1) multi-level, (2) multi-faceted, (3) interdisciplinary, and (4) polycentric governance.

Timothy Williamson has famously argued that the principle should be rejected. We analyze Williamson's argument and show that its key premise is ambiguous, and that when it is properly stated this premise no longer supports the argument against. After canvassing possible objections to our argument, we reflect upon some conclusions that suggest significant epistemological ramifications pertaining to the acquisition of knowledge from prior knowledge by deduction.

In this paper I will draw attention to an important route to external world skepticism, which I will call confidence skepticism. I will argue that we can defang confidence skepticism (though not a meeker ‘argument from might’ which has got some attention in the 20th century literature on external world skepticism) by adopting a partially psychologistic answer to the problem of priors. And I will argue that certain recent work in the epistemology of mathematics and logic provides independent support for (...) such psychologism. (shrink)

There are few indulgences academics can crave more than to have their work considered and addressed by leading researchers in their field. We have been fortunate to have two outstanding philosophers from whose work we have learned a great deal give ours their thoughtful attention. Grappling with Stephen Yablo’s, and Juan Comesaña’s comments and criticisms has helped us gain a better understanding of our ideas as well as their shortcomings. We are extremely grateful to them for the attentiveness and seriousness (...) with which they have considered our arguments and to philosophical studies for giving us this opportunity. Given the substantive difference between the two response papers, there is not much beyond sincere gratitude that we can covey to them jointly. We will therefore address them in turn. (shrink)

I offer the first sustained defence of the claim that ugliness is constituted by the disposition to disgust. I advance three main lines of argument in support of this thesis. First, ugliness and disgustingness tend to lie in the same kinds of things and properties (the argument from ostensions). Second, the thesis is better placed than all existing accounts to accommodate the following facts: ugliness is narrowly and systematically distributed in a heterogenous set of things, ugliness is sometimes enjoyed, and (...) ugliness sits opposed to beauty across a neutral midpoint (the argument from proposed intensions). And third, ugliness and disgustingness function in the same way in both giving rise to representations of contamination (the argument from the law of contagion). In making these arguments, I show why prominent objections to the thesis do not succeed, cast light on some of the artistic functions of ugliness, and, in addition, demonstrate why a dispositional account of disgustingness is correct, and present a novel problem for warrant-based accounts of disgustingness (the ‘too many reasons’ problem).

I introduce a schematic notation for formulating bilateral natural deduction systems, and I use this notation to formulate three distinct bilateral natural deduction systems for classical logic. I then propose a new criterion for bilateral harmony that I argue is superior to the existing criteria proposed in the literature. Finally, I show, at the schematic level, that all three bilateral systems meet this criterion of bilateral harmony.

Bilateral proof systems, which provide rules for both affirming and denying sentences, have been prominent in the development of proof-theoretic semantics for classical logic in recent years. However, such systems provide a substantial amount of freedom in the formulation of the rules, and, as a result, a number of different sets of rules have been put forward as definitive of the meanings of the classical connectives. In this paper, I argue that a single general schema for bilateral proof rules has (...) a reasonable claim to inferentially articulating the core meaning of all of the classical connectives. I propose this schema in the context of a bilateral sequent calculus in which each connective is given exactly two rules: a rule for affirmation and a rule for denial. Positive and negative rules for all of the classical connectives are given by a single rule schema, harmony between these positive and negative rules is established at the schematic level by a pair of elimination theorems, and the truth-conditions for all of the classical connectives are read off at once from the schema itself.

According to an act-based conception of propositions, propositions are types of cognitive or linguistic acts. Such accounts are advertised as having major metaphysical and epistemological advantages over traditional platonic accounts. However, existing versions of such accounts appeal to platonic properties and relations in order to account for the contents expressed by predicates, reintroducing many of the problems they aim to solve. Characterizing both *that a is F* and *that it’s F* as different types of “assertibles” (the former can be asserted (...) full-stop and the latter can be asserted of things), the issue can be seen as a limitation of existing act-based approaches: they apply only to a restricted class of assertibles. In this paper, I show how adopting a normative functionalist approach to linguistic meaning enables one to generalize the act-based approach to all assertibles such that no appeal to extrinsic properties and relations is needed. I show, further, how this radicalized act-based account provides the resources for a satisfactory account of our knowledge of objective states of affairs, properties, and relations (which I dub “instantiables”) in terms of our mastery of linguistic norms.

A modest theory of meaning does not attempt to give an account of the concepts expressed by the primitive expressions of a language. Throughout his career, John McDowell has argued that our semantic aspirations ought to be modest in this sense. By contrast, inferentialism, as developed by Wilfrid Sellars and Robert Brandom, is clearly an immodest theory of meaning: it aims to account for the concepts expressed by linguistic expressions in terms of the inferential rules governing their use. In this (...) paper, I defend inferentialism against all of McDowell’s criticisms, arguing that they either fail to apply to the view, or beg the question against it. (shrink)

I argue that the main existing accounts of the relationship between the beauty of environmental entities and their moral standing are mistaken in important ways. Beauty does not, as has been suggested by optimists, confer intrinsic moral standing. Nor is it the case, as has been suggested by pessimists, that beauty at best provides an anthropocentric source of moral standing that is commensurate with other sources of pleasure. I present arguments and evidence that show that the appreciation of beauty tends (...) to cause a transformational state of mind that is more valuable than mere pleasure, but that leads us to falsely represent beautiful entities as being sentient and, in turn, as having intrinsic moral standing. To this extent, beauty is not, then, a source of intrinsic moral standing; it’s a source of a more important anthropocentric value than has hitherto been acknowledged. (shrink)

When are morally good actions beautiful, when indeed they are? In this paper, it is argued that morally good actions are beautiful when they appear to express the deep or true self, and in turn tend to give rise to an emotion which is characterised by feelings of being moved, unity, inspiration, and meaningfulness, inter alia. In advancing the case for this claim, it is revealed that there are additional sources of well-formedness in play in the context of moral beauty (...) in addition to those that have tended to be focused on to date: one which is connected to imagining a deep location for the goodness concerned, and another which is connected to imagining that the goodness stems from capacities which are essential to the person. (shrink)

According to the most important objection to the existence of moral beauty, true judgements of moral beauty are not possible as moral judgements require being motivated to act in line with the moral judgement made, and judgements of beauty require not being motivated to act in any way. Here, I clarify the argument underlying the objection and demonstrate that it does not show that moral beauty does not exist. I present two responses: namely, that the beauty of moral beauty does (...) not lie in the moral goodness per se (the ‘adjacent properties’ response), and that only a dispositional motivation to act is required for the moral judgements that are typically made as part of judgements of moral beauty, whereas aesthetic judgements only rule out state motivations to act (the ‘equivocation of motivation required’ response). In addressing the objection, I show how moral beauty is consistent with disinterestedness, and so should be accepted more widely; also clarifying where the beauty in moral beauty resides, and how the moral–aesthetic distinction should be drawn.

Why are moral actions beautiful, when indeed they are? This paper assesses the view, found most notably in Schiller, that moral actions are beautiful just when they present the appearance of freedom by appearing to be the result of internal harmony (the Schillerian Internal Harmony Thesis). I argue that while this thesis can accommodate some of the beauty involved in contrasts of the ‘continent’ and the ‘fully’ virtuous, it cannot account for all of the beauty in such contrasts, and so (...) needs to be weakened considerably (to the Internal Harmony Thesis). To account for the remaining beauty that cannot be fully accommodated even by this revised thesis, as well as the beauty contained in contrasts that involve agents who experience internal conflict as a result of being sensitive to different sources of moral value to an appropriate extent, a number of further theses need to be posited: namely, that the beauty of some moral actions is to be accommodated in terms of internal disharmony (the Internal Disharmony Thesis), and in terms of a felt harmony between the appreciator of the action and the executor of the action (the Affective Harmony Thesis). As such, in contrast to Schiller, I suggest that we need to take a pluralist and context-sensitive approach to accommodating the beauty of moral actions. (shrink)

Given that conspiracies exist, can we be justified in dismissing conspiracy theories without concerning ourselves with specific details? I answer this question by focusing on contrarian conspiracy theories, theories about conspiracies that conflict with testimony from reliable sources of information. For example, theories that say the CIA masterminded the assassination of John F. Kennedy, 9/11 was an inside job, or the Freemasons are secretly running the world are contrarian conspiracy theories. When someone argues for a contrarian conspiracy theory, their options (...) are to appeal to eyewitness testimony, incriminating documents, photographs, audio recordings, video recordings, allegedly scientific evidence, anomalies, or considerations of cui bono (who benefits). Most laypeople don’t know how to adequately respond to arguments for contrarian conspiracy theories, but this doesn’t mean that it’s dogmatic to reject them. I argue that many laypeople are defeasibly justified in rejecting a variety of contrarian conspiracy theories based on testimony and this justification is rarely defeated by arguments for contrarian conspiracy theories even if we don’t know how to respond to these arguments.

An “inferentialist” semantic theory for some language L aims to account for the meanings of the sentences of L solely in terms of the inferential rules governing their use. A “hyper-inferentialist” theory admits into the semantics only “narrowly inferential” rules that normatively relate sentences of L to other sentences of L. A “strong inferentialist” theory also admits into the semantics “broadly inferential” rules that normatively relate perceptual states to sentences of L or sentences of L to intentional actions. It is (...) widely thought that only the latter of these two sorts of semantic theories is at all viable. I argue here that the opposite is so. Negatively, strong inferentialism is viciously circular: including rules into the semantic theory that relate perceptual states to sentences of the language requires us to appeal, in individuating those perceptual states, to the very meanings for which we are supposed to be inferentially accounting. Hyper-inferentialism does not face this problem because it does not appeal to any nonlinguistic states. Positively, though hyper-inferentialism is widely thought to be a theoretical non-starter, I argue here that it is a genuine theoretical possibility insofar as it essentially includes cross-perspectival inferences, inferences along the lines of the one from the sentences “The ball is in front of n,” “The ball is red,” and “The lighting is good” to the sentence “n sees that the ball is red.” I make the further exegetical claim that Robert Brandom, though unanimously taken to be a strong inferentialist, is in fact a hyper-inferentialist.

Mathematical knowledge and moral knowledge (or normative knowledge more generally) can seem intuitively puzzling in similar ways. For example, taking apparent human knowledge of either domain at face value can seem to require accepting that we benefited from some massive and mysterious coincidence. In the mathematical case, a pluralist partial response to access worries has been widely popular. In this paper, I will develop and address a worry, suggested by some works in the recent literature like (Clarke-Doane, 2020 ), that (...) connections between ought facts and action prevent us from giving a similarly pluralist response to moral access worries.

Some authors argue that it is permissible for clinicians to conscientiously provide abortion services because clinicians are already allowed to conscientiously refuse to provide certain services. Call this the symmetry thesis. We argue that on either of the two main understandings of the aim of the medical profession—what we will call “pathocentric” and “interest‐centric” views—conscientious refusal and conscientious provision are mutually exclusive. On pathocentric views, refusing to provide a service that takes away from a patient's health is professionally justified because (...) there are compelling reasons, based on professional standards, to refuse to provide that service (e.g., it does not heal, and it is contrary to the goals of medicine). However, providing that same service is not professionally justified when providing that service would be contrary to the goals of medicine. Likewise, the thesis turns out false on interest‐centric views. Refusing to provide a service is not professionally justified when that service helps the patient fulfill her autonomous preferences because there are compelling reasons, based on professional standards, to provide that service (e.g., it helps her achieve her autonomous preferences, and it would be contrary to the goals of medicine to deny her that service). However, refusing to provide that same service is not professionally justified when refusing to provide that service would be contrary to the goals of medicine. As a result, on either of the two most plausible views on the goals of medicine, the symmetry thesis turns out false. (shrink)

In this article, we reflect on our experiences teaching a PWOL course called Philosophy for Living. The course uses modules focused on different historical philosophical ways of life (Epicureanism, Stoicism, Confucianism, Existentialism, etc.) to engage students in exploring how philosophy can be a way of life and how its methods, virtues, and ideas can improve their own lives. We describe and compare our experiences with two central aspects of our approach: engagement with diversity and the use of immersive experiences and (...) assignments. In particular, we discuss how we recognize and center various forms of diversity in philosophy—cultural and gender diversity, but also diversity in how and in what forms philosophy can be done and what “philosophy as a way of life” can be. We also examine how the experimental and experiential aspects of immersive assignments promote deeper understanding and create possibilities for personal transformation. (shrink)

In this paper I argue for an association between impurity and explanatory power in contemporary mathematics. This proposal is defended against the ancient and influential idea that purity and explanation go hand-in-hand (Aristotle, Bolzano) and recent suggestions that purity/impurity ascriptions and explanatory power are more or less distinct (Section 1). This is done by analyzing a central and deep result of additive number theory, Szemerédi’s theorem, and various of its proofs (Section 2). In particular, I focus upon the radically impure (...) (ergodic) proof due to Furstenberg (Section 3). Furstenberg’s ergodic proof is striking because it utilizes intuitively foreign and infinitary resources to prove a finitary combinatorial result and does so in a perspicuous fashion. I claim that Furstenberg’s proof is explanatory in light of its clear expression of a crucial structural result, which provides the “reason why” Szemerédi’s theorem is true. This is, however, rather surprising: how can such intuitively different conceptual resources “get a grip on” the theorem to be proved? I account for this phenomenon by articulating a new construal of the content of a mathematical statement, which I call structural content (Section 4). I argue that the availability of structural content saves intuitive epistemic distinctions made in mathematical practice and simultaneously explicates the intervention of surprising and explanatorily rich conceptual resources. Structural content also disarms general arguments for thinking that impurity and explanatory power might come apart. Finally, I sketch a proposal that, once structural content is in hand, impure resources lead to explanatory proofs via suitably understood varieties of simplification and unification (Section 5).

Why must incompatibility be symmetric? An odd question, but recent work in the semantics of non-classical logic, which appeals to the notion of incompatibility as a primitive and defines negation in terms of it, has brought this question to the fore. Francesco Berto proposes such a semantics for negation argues that, since incompatibility must be symmetric, double negation introduction must be a law of negation. However, he offers no argument for the claim that incompatibility really must be symmetric. Here, I (...) provide such an argument, showing that, insofar as we think of incompatibility in normative pragmatic terms, it can play its basic pragmatic function only if it is symmetric. The upshot is that we can vindicate Berto’s claim about the symmetry of incompatibility but only if we, pace Berto, think about incompatibility, in the first instance, as a pragmatic relation between acts rather than a semantic relation between contents.

Räsänen and Ahola-Launonen recently offered a commentary on an ethical analysis I co-authored with Julian Savulescu on the use of semaglutide-based weight-loss drugs such as Ozempic. In this response, I continue the discussion by engaging their concerns about the narrow framing of our analysis with respect to the structural determinants of health and the conditions of autonomy, as well as the role of race, class and gender in shaping stigma and access to treatment. I argue that Räsänen and Ahola-Launonen’s critique (...) and the conclusion they draw are largely in alignment with our paper and that the absence in our account of a more expansive conception of autonomy and a broader discussion of race, class and gender are fair criticisms. In what follows, I add nuance to these dimensions and caution against critiques of unjust structures that risk reproducing injustice by inadvertently denying the agency, self-respect and inclusion of marginalised groups.

This note points out a conflict between some common intuitions about metaphysical possibility. On the one hand, it is appealing to deny that there are robust counterfactuals about how various physically impossible substances would interact with the matter that exists at our world. On the other hand, our intuitions about how concepts like MOUNTAIN apply at other metaphysically possible worlds seem to presuppose facts about ‘solidity’ which cash out in terms of these counterfactuals. I consider several simple attempts to resolve (...) this conflict and note they all fall short. (shrink)

I motivate and develop a use-based semantic theory in opposition to the dominant paradigm in philosophical and linguistic semantics. Drawing inspiration from Wilfrid Sellars, I argue that contemporary semantic theories are faced with a basic problem of explanatory circularity. These theories universally presuppose that worldly knowledge of such things as properties or sets of possible worlds precedes and underlies knowledge of meaning. However, I argue that it is only through learning a language--mastering the rules governing the use of the expressions (...) belonging to that language--that speakers can possibly have knowledge of the worldly entities appealed to by semanticists at the base level of their semantic theories. In response to this fundamental problem, I develop a formal semantic framework in which the meaning of a sentence is understood directly in terms of its role in discourse. In contrast to existing semantic frameworks, this framework does not presuppose speakers' worldly knowledge, and so is actually able to explain it. The result is not just a new kind of semantic theory, but a new conception of the relation between meaning and the world. (shrink)

Natural experiments are an increasingly popular research design in political science. This popularity raises a number of questions. First, what are natural experiments and why are they appealing? Second, what makes a good natural experiment? And finally, are natural experiments able to provide resources for knowledge production that other methodologies cannot or do not provide? Using Mary Morgan’s and Thad Dunning’s recent work on natural experiments, I offer answers to the first two questions and use the analysis to argue that (...) natural experiments highlight features of knowledge production that support methodological pluralism and the multiple aims of research.

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain (...) that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.

I argue that current discussions of the epistemological significance of reflection have entangled concerns about reflection with agential concerns. I begin by showing that a central strand of internalist criticism finds externalism unsatisfactory because it fails to provide a particular kind of self-knowledge, knowledge about the epistemic status of one’s own beliefs. Identifying this internalist motivation as the desire for a kind of self-knowledge opens up new possibilities and suggests new conceptual resources. I employ one of these resources—Richard Moran’s distinction (...) between the theoretical stance and the deliberative stance—to locate two types of reflection: mere reflective awareness of one’s attitudes and agent-awareness of one’s attitudes. I then examine Ernest Sosa’s account of the importance of reflection, showing how Moran’s distinction brings out the centrality of agential concerns in Sosa’s argument for reflective knowledge. I also consider briefly its relevance to fully apt knowledge. While I focus on Sosa’s epistemology, the point extends to internalism more generally. (shrink)

When we raise children what we are typically aiming for is a kind of flourishing; we want children to live well as children, and to grow to become adults who live well too. Undoubtedly, part of what we are aiming for when we aim for a child’s flourishing is that they meet their developmental milestones well, and that they succeed among their peers. We are also generally interested in how a child regards themselves; we want children to believe that they (...) have value, and that what they care about has value too. We also typically want children to have an appreciation for their relative value among others; that they are important among many other important beings, and we want them to act well in that knowledge. Of course, not all persons who raise children aim for those ends. Some do not care for how a child conceives of themselves, or whether the child flourishes at all. Others care for their children, and how they conceive of themselves, but aim poorly. As result, some children come to believe that they only deserve love and kindness when they succeed at meeting a caregiver’s ends. Some children come to believe that they have no worth at all. And yet other children, rather than believing they are unworthy, come to regard themselves as of superior worth; as children, for example, who bully and sneer at other children for being a different race, a different class, gender, ability, etc. may. When a child comes to understand themselves in these terms, we typically see it at best as morally problematic, and at worst as a tragedy. Despite our interest in children’s self-conceptions, and the vast literature on how to conceive of and regard children, there is relatively little regarding how children should conceive of and regard themselves. In order to explain how children should conceive of themselves it is my contention that a new account of self-respect is needed for the context of childhood; one that is responsive to the moral value of children, as well as their developmental capacities to recognize that value. Given that developmental psychology is complex and subject to significant variation as children develop, my aim in this paper is to offer a snapshot of what I take self-respect to amount to in early childhood. In particular, I focus on an account fitting for children between three to six years of age. (shrink)
