We offer a general framework for theorizing about the structure of knowledge and belief in terms of the comparative normality of situations compatible with one’s evidence. The guiding idea is that, if a possibility is sufficiently less normal than one’s actual situation, then one can know that that possibility does not obtain. This explains how people can have inductive knowledge that goes beyond what is strictly entailed by their evidence. We motivate the framework by showing how it illuminates knowledge about (...) the future, knowledge of lawful regularities, knowledge about parameters measured using imperfect instruments, the connection between knowledge, belief, and probability, and the dynamics of knowledge and belief in response to new evidence.

How is what we believe related to how we act? That depends on what we mean by ‘believe’. On the one hand, there is what we're sure of: what our names are, where we were born, whether we are sitting in front of a screen. Surety, in this sense, is not uncommon — it does not imply Cartesian absolute certainty, from which no possible course of experience could dislodge us. But there are many things that we think that we are (...) not sure of. For example, you might think that it will rain sometime this month, but not be sure that it will. Both what we're sure of and what we think have important normative connections to action. But the connections are quite different. This paper explores these issues with respect to assertion, inquiry, and decision making. We conclude by arguing that there is no theoretically significant notion of ‘full belief’ intermediate in strength between thinking and being sure. (shrink)

Consider the sentence “Lois knows that Superman flies, but she doesn’t know that Clark flies”. In this paper we defend a Millian contextualist semantics for propositional attitude ascriptions, according to which ordinary uses of this sentence are true but involve a mid-sentence shift in context. Absent any constraints on the relevant parameters of context sensitivity, such a semantics would be untenable: it would undermine the good standing of systematic theorizing about the propositional attitudes, trivializing many of the central questions of (...) epistemology, the philosophy of mind, and the philosophy of action. In response to this problem, we prove a series of tenability results. We show that, given certain constraints on the parameters of context sensitivity, there is a broad class of principles of propositional attitude psychology whose good standing follows from corresponding claims about people’s mental representations. But these constraints also have some surprising consequences: they are jointly incompatible with coarse-grained theories of propositions, and they are in tension with a natural picture of how speakers and hearers coordinate on the interpretation of attitude ascriptions. In light of these consequences we explore different ways in which the contextualist picture might be developed, and argue that our preferred way compares favorably with Fregeanism and neo-Russellianism.

This chapter offers an opinionated introduction to higher-order formal languages with an eye towards their applications in metaphysics. A simply relationally typed higher-order language is introduced in four stages: starting with first-order logic, adding first-order predicate abstraction, generalizing to higher-order predicate abstraction, and finally adding higher-order quantification. It is argued that both β-conversion and Universal Instantiation are valid on the intended interpretation of this language. Given these two principles, it is then shown how we can use pure higher-order logic to (...) ask, and begin to answer, metaphysical questions with non-trivial implications. In particular, while we must reject the popular idea that structural differences between sentences correspond to parallel distinctions in the logical structure of extra-linguistic reality, it may still be possible to give a purely logical characterization of objectual aboutness and related notions.

We show that, contrary to conventional wisdom, Frege’s distinction between sense and reference does not reconcile a classical logic of identity with apparent counterexamples to it involving proper names embedded under propositional attitude verbs.

Conditional excluded middle (CEM) is the following principe of counterfactual logic: either, if it were the case that φ, it would be the case that ψ, or, if it were the case that φ, it would be the case that not-ψ. I will first show that CEM entails the identity of indiscernibles, the falsity of physicalism, and the failure of the modal to supervene on the categorical and of the vague to supervene on the precise. I will then argue that (...) we should accept these startling conclusions, since CEM is valid. (shrink)

This paper investigates a generalization of Boolean algebras which I call agglomerative algebras. It also outlines two conceptions of propositions according to which they form an agglomerative algebra but not a Boolean algebra with respect to conjunction and negation.

We defend the thesis that every necessarily true proposition is always true. Since not every proposition that is always true is necessarily true, our thesis is at odds with theories of modality and time, such as those of Kit Fine and David Kaplan, which posit a fundamental symmetry between modal and tense operators. According to such theories, just as it is a contingent matter what is true at a given time, it is likewise a temporary matter what is true at (...) a given possible world; so a proposition that is now true at all worlds, and thus necessarily true, may yet at some past or future time be false in the actual world, and thus not always true. We reconstruct and criticize several lines of argument in favor of this picture, and then argue against the picture on the grounds that it is inconsistent with certain sorts of contingency in the structure of time.

We often speak as if there are merely possible people—for example, when we make such claims as that most possible people are never going to be born. Yet most metaphysicians deny that anything is both possibly a person and never born. Since our unreflective talk of merely possible people serves to draw non-trivial distinctions, these metaphysicians owe us some paraphrase by which we can draw those distinctions without committing ourselves to there being merely possible people. We show that such paraphrases (...) are unavailable if we limit ourselves to the expressive resources of even highly infinitary first-order modal languages. We then argue that such paraphrases are available in higher-order modal languages only given certain strong assumptions concerning the metaphysics of properties. We then consider alternative paraphrase strategies, and argue that none of them are tenable. If talk of merely possible people cannot be paraphrased, then it must be taken at face value, in which case it is necessary what individuals there are. Therefore, if it is contingent what individuals there are, then the demands of paraphrase place tight constraints on the metaphysics of properties: either (i) it is necessary what properties there are, or (ii) necessarily equivalent properties are identical, and having properties does not entail even possibly being anything at all.

Philosophy and Phenomenological Research, EarlyView.

This paper is a study of higher-order contingentism – the view, roughly, that it is contingent what properties and propositions there are. We explore the motivations for this view and various ways in which it might be developed, synthesizing and expanding on work by Kit Fine, Robert Stalnaker, and Timothy Williamson. Special attention is paid to the question of whether the view makes sense by its own lights, or whether articulating the view requires drawing distinctions among possibilities that, according to (...) the view itself, do not exist to be drawn. The paper begins with a non-technical exposition of the main ideas and technical results, which can be read on its own. This exposition is followed by a formal investigation of higher-order contingentism, in which the tools of variable-domain intensional model theory are used to articulate various versions of the view, understood as theories formulated in a higher-order modal language. Our overall assessment is mixed: higher-order contingentism can be fleshed out into an elegant systematic theory, but perhaps only at the cost of abandoning some of its original motivations.

We offer an interpretation of the mental files framework that eliminates the metaphor of files, information being contained in files, etc. The guiding question is whether, once we move beyond the metaphors, there is any theoretical role for files. We claim not. We replace the file-metaphor with two theses: the semantic thesis that there are irreducibly relational representational facts (viz. facts about the coordination of representations); and the metasemantic thesis that processes tied to information-relations ground those facts. In its canonical (...) statement, the ‘file’-theory makes reference to a certain kind of relational representational feature, and a certain kind of mental activity. Mental files need not come into it. In short, we posit mental filing without mental files. Our interpretation avoids awkward problems that arise on the standard interpretation and clarifies the explanatory commitments of the theory. (shrink)

In an essay on performance-enhancing drugs, author Chuck Klosterman (2007) argues that the category of enhancers extends from hallucinogens used to inspire music to steroids used to strengthen athletes—and he criticizes those who would excuse one means of enhancement while railing against the other as a form of cheating: After the summer of 1964, the Beatles started taking serious drugs, and those drugs altered their musical performance. Though it may not have been their overt intent, the Beatles took performance-enhancing drugs. (...) And . . . absolutely no one holds it against them.

In Talking about, Unnsteinsson defends an intentionalist theory of reference by arguing that confused referential intentions degrade reference. Central to this project is a “belief model” of both identity confusion and unconfused thought. By appealing to a well‐known argument from Campbell, I argue that this belief model falls short, because it fails to explain the inferential behavior it promises to explain. Campbell's argument has been central in the contemporary literature on Frege's puzzle, but Unnsteinsson's account of confusion provides an opportunity (...) for more clarity about how the argument is best interpreted, and what it shows.

What explains why we are subjects for whom objects can have value, and what explains which objects have value for us? Axiologicians say that the value of humanity is the answer. I argue that our value, no matter what it is like, cannot perform this task. We are animals among others. An explanation of the value of objects for us must fit into an explanation of the value of objects for animals generally. Different objects have value for different animals. Those (...) differences depend on differences in animal natures and, in particular, on the diverse characteristic capacities of different animals. Once we invoke animal natures, there is nothing for the value of animality, including the value of humanity, to explain. (shrink)

On the traditional relationalist conception of singular thought, a thought has singular content when it is based on an ‘information relation’ to its object. Recent work rejects relationalism and suggests singular thoughts are distinguished from descriptive thoughts by their inferential role: only thoughts with singular content can be employed in ‘direct’ inferences, or inferences that ‘trade on identity’. Firstly this view is insufficiently clear, because it conflates two distinct ideas—one about a kind of inference, the other a kind of process (...) that grounds inferences—under the title, ‘trading on identity’. Secondly, this leaves us without a notion that can be used as an alternative to relationalism about singular thought. The first notion is no more applicable to singular than to descriptive thought. The second may help us better understand singular thought, but does so, not by replacing the view that singular thoughts are information-based, but by helping us understand the nature of information-based thought.

In a recent paper, Sylvia Wenmackers and Leon Horsten discuss how the concept of a fair infinite lottery can best be extended to denumerably infinite lotteries.

According to traditional versions of the mental file theory, we should posit _mental files_—that is, mental representations with containment structure—to explain both rational relations between the attitudes, and the persistence of the attitudes across time. However, Goodman and Gray ( 2022 ) offer a revisionary interpretation of the file framework, according to which its explanatory commitments are better presented by positing _mental filing_, as a process, but not _mental files_, as mental representations with file structure. Goodman and Gray (...) focus on a certain class of synchronic explanations, but files have also been thought to play an essential diachronic role in the maintenance and update of object-directed thought. This paper has two aims. First, we clarify the aims and commitments of Goodman and Gray ( 2022 ). Second, we extend their mental filing view to show how it can account for continued belief, change of mind and persistence of the attitudes in general. (shrink)

This paper discusses a puzzle, the heart of which is this question: How is it that real individuals can resemble fictional individuals? It seems that any answer given by one who has taken a stand on the ontology of fictional individuals will come with significant drawbacks. An Anti-Realist will have to explain, or explain away, the apparent truth of our positive assertions of resemblance, while a Realist will have to explain how we are to understand resemblance in light of either (...) the further claim that fictional characters are not associated with properties in the same way real individuals are, or that fictional characters are nonexistent or nonactual. I here survey the different Realist and Anti-Realist strategies in hopes that reflection on (mainly the drawbacks of) each will aid those who are curious about ontologies which may include fictionalia.

The purpose of this paper is to dissolve paradoxes of the infinite by correctly identifying the infinite natural numbers.

Although at first glance, “facts” are the paradigms of straightforwardness, something about facts seems to invite perpetual controversy and dichotomizing. Innumerable bifurcations on the topic have included "Facts vs. Theories”, “Facts vs. Appearance”, "Facts vs. Values", ... and, popular nowadays, "(Real)Facts vs. Fake Facts". This paper most aligns with the facts vs. theories model, so far as whatever facts are, theories seem to be constructed stories that are necessary for connecting and interpreting the facts. Yet the boundary between the two (...) is fluid and fuzzy: Fact in one context is theory in another, depending on what is being accepted or contested at the time. This paper’s views are compatible with—but neutral on the plausibility of having—an optimism like Peirce’s that scientific inquiry may nonetheless converge towards a consensus. To illustrate the challenges of finding “straightforward” facts, the paper includes a case example, related to research on possible health effects of exposure to electromagnetic-field radiation (EMF). _ The source paper for this 2018 update was originally presented at the University of Waterloo 30th Anniversary Philosophy Conference, 1993.

Did Plato intend the laws of the Laws to change? While most scholars agree that there is to be legal change in Magnesia, I contend that this issue has been clouded by confusing three distinct questions: (1) whether there are legal mechanisms for changing the law in Magnesia, (2) what the attitudes of Magnesian citizens towards innovation and legal change are, and (3) whether Plato thinks the law is always the ultimate political authority. Once we separate these issues and look (...) at the relevant texts more closely, we see that the Athenian Visitor is primarily concerned with supplementing the original lawgiver’s laws and that any innovation that occurs should be consistent with this lawcode. This does not settle the question about whether it is always right to act in accordance with the existing laws, though it does provide a valuable framework for understanding a central aspect of Platonic political philosophy. Thus, although Plato’s ideal places knowledge above the law, in practice the laws of Magnesia will be fixed and authoritative for those people living under them. (shrink)

When should you engage with difficult arguments against your cherished controversial beliefs? The primary conclusion of this book is that your obligations to engage with counterarguments are more limited than is often thought. In some standard situations, you shouldn't engage with difficult counterarguments and, if you do, you shouldn't engage with them open-mindedly. This conclusion runs counter to aspects of the Millian political tradition and political liberalism, as well as what people working in informal logic tend to say about argumentation. (...) -/- Not all misleading arguments wear their flaws on their sleeve. Each step of a misleading argument might seem compelling and you might not be able to figure out what's wrong with it. Still, even if you can't figure out what's wrong with an argument, you can know that it's misleading. One way to know that an argument is misleading is, counterintuitively, to lack expertise in the methods and evidence-types employed by the argument. When you know that a counterargument is misleading, you shouldn't engage with it open-mindedly and sometimes shouldn't engage with it at all. You shouldn't engage open-mindedly because you shouldn't be willing to reduce your confidence in response to arguments you know are misleading. And you sometimes shouldn't engage closed-mindedly, because to do so can be manipulative or ineffective. -/- In making this case, Jeremy Fantl discusses echo chambers and group polarization, the importance in academic writing of a sympathetic case for the opposition, the epistemology of disagreement, the account of open-mindedness, and invitations to problematic academic speakers.

The so-called ‘mental files theory’ in the philosophy of mind stems from an analogy comparing object-concepts to ‘files’, and the mind to a ‘filing system’. Though this analogy appears in philosophy of mind and language from the 1970s onward, it remains unclear to many how it should be interpreted. The central commitments of the mental files theory therefore also remain unclear. Based on influential uses of the file analogy within philosophy, I elaborate three central explanatory roles for mental files. Next, (...) I outline several common criticisms of the file picture, which have been a source of resistance to the view. Finally, I outline several interpretations of the theory, thus highlighting that the best interpretation of the file-theory's central analogy remains a live issue. (shrink)

In this paper, we offer a brief, critical survey of contemporary work on truth. We begin by reflecting on the distinction between substantivist and deflationary truth theories. We then turn to three new kinds of truth theory—Kevin Scharp's replacement theory, John MacFarlane's relativism, and the alethic pluralism pioneered by Michael Lynch and Crispin Wright. We argue that despite their considerable differences, these theories exhibit a common "pluralizing tendency" with respect to truth. In the final section, we look at the underinvestigated (...) interface between metaphysical and formal truth theories, pointing to several promising questions that arise here. (shrink)

Influential work on proper names, most centrally associated with Kripke (1980), has had a significant influence in the literature on singular thought. The dominant position among contemporary singularists is that we can think singular thoughts about any object we can refer to by name and that, given the range of cases in which it is possible to refer using a name, name use in fact enables singular thought about a name's referent. I call this the extended name-based thought thesis (extended-NBT). (...) This chapter outlines the reasoning and presumptions of theorists who adopt extended NBT, and also outlines a set of reasons to resist it. The piece is distinctive in approaching the question of the relation between names and singular thought by focusing on the function of names and what this function entails (or doesn’t) about the kinds of thoughts (singular or descriptive) we have when we use names to communicate. In short, thinking about the function of names tells against the claim that name-use enables singular thought. (shrink)

Plato is often acknowledged as the first philosophical critic of democracy and his Republic is regularly taken as a paradigm of an anti-democratic work. While it is true that Plato objected to much about the democracy of his own time, Plato’s political theorizing also reveals an interest in improving democratic institutions. This chapter explores three themes in Plato’s thinking about democracy: firstly, Plato's insistence that rulers should be knowledgeable and his claim that most people are politically incompetent (§1); secondly, Plato's (...) criticisms of oratory and the corrupting effects of public rhetoric (§2); thirdly, Plato's use of democratic institutions in the Laws (§3). Once we appreciate these different evaluations of democratic practices, we can see that Plato was not simply ‘anti-democratic’ or ‘pro-democratic’ but thought some democratic practices should be abandoned, some reformed, and some adopted.

It's often said that according to deflationary theories of truth, truth is not a ‘substantial’ property. While this is a fine slogan, it is far from transparent what deflationists mean (or ought to mean) in saying that truth is ‘insubstantial’. Focusing so intently upon the concept of truth and the word ‘true’, I argue, deflationists and their critics have been insufficiently attentive to a host of metaphysical complexities that arise for deflationists in connection with the property of truth. My aim (...) is to correct several misunderstandings as to what deflationists are after here—including some harboured by deflationists themselves—and to offer an account of the commitments about truth's nature that they ought to undertake. In developing this account, I focus particularly upon the issue of what metaphysics of truth a Horwichian minimalist ought to adopt. (shrink)

Certain realists about properties and relations identify them with universals. Furthermore, some hold that for a wide range of meaningful predicates, the semantic contribution to the propositions expressed by the sentences in which those predicates figure is the universal expressed by the predicate. I here address ontological issues raised by predicates first introduced to us via works of fiction and whether the universal realist should accept that any such predicates express universals. After assessing arguments by Braun, D. and Sawyer, S. (...) for fictional universal anti-realism, I propose a novel, Kripke-inspired argument for the same conclusion. I ultimately defend the claim that while this argument presents the strongest case for fictional universal anti-realism, it is nonetheless unsound. I conclude that nothing stands in the way of accepting that some fictional predicates express fictional universals. (shrink)

Differential privacy (DP) aims to confer data processing systems with inherent privacy guarantees, offering strong protections for personal data. But DP’s approach to privacy carries with it certain assumptions about how mathematical abstractions will be translated into real-world systems, which—if left unexamined and unrealized in practice—could function to shield data collectors from liability and criticism, rather than substantively protect data subjects from privacy harms. This article investigates these assumptions and discusses their implications for using DP to govern data-driven systems. In (...) Parts 1 and 2, we introduce DP as, on one hand, a mathematical framework and, on the other hand, a kind of real-world sociotechnical system, using a hypothetical case study to illustrate how the two can diverge. In Parts 3 and 4, we discuss the way DP frames privacy loss, data processing interventions, and data subject participation, arguing it could exacerbate existing problems in privacy regulation. In part 5, we conclude with a discussion of DP’s potential interactions with the endogeneity of privacy law, and we propose principles for best governing DP systems. In making such assumptions and their consequences explicit, we hope to help DP succeed at realizing its promise for better substantive privacy protections. (shrink)

Philosophers of science have insisted that evidence of underlying mechanisms is required to support claims about the effects of medical interventions. Yet evidence about mechanisms does not feature on dominant evidence-based medicine “hierarchies.” After arguing that only inferences from mechanisms (“mechanistic reasoning”)—not mechanisms themselves—count as evidence, I argue for a middle ground. Mechanistic reasoning is not required to establish causation when we have high-quality controlled studies; moreover, mechanistic reasoning is more problematic than has been assumed. Yet where the problems can (...) be overcome, mechanistic reasoning can and should be used as evidence. (shrink)

It has become popular of late to identify the phenomenon of thinking a singular thought with that of thinking with a mental file. Proponents of the mental files conception of singular thought claim that one thinks a singular thought about an object o iff one employs a mental file to think about o. I argue that this is false by arguing that there are what I call descriptive mental files, so some file-based thought is not singular thought. Descriptive mental files (...) are mental files for which descriptive information plays four roles: determines which object the file is about, if any, it sets limits on possible mistakes that fall within the scope of successful reference for the file, it acts as a ‘gatekeeper’ for the file, and it determines persistence conditions for the file. Contrary to popular assumption, a description playing these roles is consistent with the file-theoretic framework. Recognising this allows us to distinguish the notion of singular thought from that of file-thinking and better understand the nature and role of both. (shrink)

Objectives -/- Surveys in various countries suggest 17% to 80% of doctors prescribe ‘placebos’ in routine practice, but prevalence of placebo use in UK primary care is unknown. Methods -/- We administered a web-based questionnaire to a representative sample of UK general practitioners. Following surveys conducted in other countries we divided placebos into ‘pure’ and ‘impure’. ‘Impure’ placebos are interventions with clear efficacy for certain conditions but are prescribed for ailments where their efficacy is unknown, such as antibiotics for suspected (...) viral infections. ‘Pure’ placebos are interventions such as sugar pills or saline injections without direct pharmacologically active ingredients for the condition being treated. We initiated the survey in April 2012. Two reminders were sent and electronic data collection closed after 4 weeks. Results -/- We surveyed 1715 general practitioners and 783 (46%) completed our questionnaire. Our respondents were similar to those of all registered UK doctors suggesting our results are generalizable. 12% (95% CI 10 to 15) of respondents used pure placebos while 97% (95% CI 96 to 98) used impure placebos at least once in their career. 1% of respondents used pure placebos, and 77% (95% CI 74 to 79) used impure placebos at least once per week. Most (66% for pure, 84% for impure) respondents stated placebos were ethical in some circumstances. Conclusion and implications -/- Placebo use is common in primary care but questions remain about their benefits, harms, costs, and whether they can be delivered ethically. Further research is required to investigate ethically acceptable and cost-effective placebo interventions. (shrink)

This paper is about the relevance of attitude-ascriptions to debates about singular thought. It examines a methodology (common to early acquaintance theorists [Kaplan 1968] and recent critics of acquaintance [Hawthorne and Manley 2012], which assumes that the behaviour of ascriptions can be used to draw conclusions about singular thought. Although many theorists (e.g. [Recanati 2012]) reject this methodology, the literature lacks a detailed examination of its implications and the challenges faced by proponents and critics. I isolate an assumption of the (...) methodology, which I call the tracking assumption: that an attitude-ascription which states that s Φ's that P is true iff s has an attitude, of Φ-ing, which is an entertaining of the content P (with entertain used in a stipulated sense). I argue that the tracking assumption must be rejected, not because it has deflationary consequences, but because it leads to unstable commitments. I also show that there are independent reasons to reject it, because ordinary attitude ascriptions underdetermine even the truth-conditions of the mental-states they ascribe. However, I argue, this does not involve rejecting the claim that attitude-ascriptions express relations between agents and contents. Instead, they state different relations depending on contextual factors other than the nature of the mental-states ascribed. (shrink)

This paper has a narrow and a broader target. The narrow target is a particular version of what I call the mental-files conception of singular thought, proposed by Robin Jeshion, and known as cognitivism. The broader target is the MFC in general. I give an argument against Jeshion's view, which gives us preliminary reason to reject the MFC more broadly. I argue Jeshion's theory of singular thought should be rejected because the central connection she makes between significance and singularity does (...) not hold. However, my argument grants Jeshion's claim that there is a connection between significance and file-thinking. The upshot is not only that we have reason to reject Jeshion's significance constraint on singular thought, but that we have reason to question the connection made by MFC proponents between file-thinking and singularity.

We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages. We argue that biologists regularly provide this type of explanation when they attribute conserved functions to phenotypic and genetic traits. The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and cell biology. (...) We use these examples to show how the study of conserved functions can integrate knowledge of a trait’s causal effects on fitness and its history of natural selection without invoking adaptation. We also show how conserved function provides a novel basis for addressing objections against evolutionary functions raised by Robert Cummins. (shrink)

Th ere is much controversy surrounding the nature of the relation between fictional individuals and possible individuals. Some have argued that no fictional individual is a possible individual; others have argued that (some) fictional individuals just are (merely) possible individuals. In this paper, I off er further grounds for believing the theory of fictional individuals defended by Amie Thomasson,viz., Artifactualism, by arguing that her view best allows one to make sense of this puzzling relation. More specifically, when we realize that (...) the view allows for an identification of merely possible individuals with fictional individuals, we seethat the utility, and hence the level of credence lent to Artifactualism, is increased. After arguing for this thesis, I respond to three of the most pressing worries. (shrink)

This paper’s most general aim is to illuminate the disagreement between singularists about thought (who claim there are non-descriptive thoughts about ordinary external objects), and descriptivists about thought (who claim all thought about ordinary external objects is descriptive). It does this by clarifying the common claim that singular thoughts have an anchoring role with respect to thought in general and by making two further claims: 1) some of the putative disagreements between singularists and descriptivists are illusory once properly understood, and (...) 2) singularists can more productively argue for their view by separating it from some of the framework in which it is commonly packaged. Separating the singular/descriptive thought distinction from the structured content framework, and casting the singularist’s central claim as one about the structure or form of what I will call referentially anchored thoughts, allows us to move past a common kind of impasse.

In this paper, I discuss two concerns for pluralist truth theories: a concern about a key detail of these theories and a concern about their viability. The detail-related concern is that pluralists have relied heavily upon the notion of a domain, but it is not transparent what they take domains to be. Since the notion of a domain has been present in philosophy for some time, it is important for many theorists, not only truth pluralists, to be clear on what (...) domains are and what work they can do. The viability-related concern is that it’s not clear how a pluralist truth theory could explain the truth-conditions of mixed atomic propositions. To address this concern, truth pluralists should recognize something to which they have not been sufficiently attentive: that some atomic propositions belong to more than one domain. But, recognizing this requires rethinking the relationships between the nature of propositions, their membership in domains, and their truth. I address these issues and propose an understanding of them that is preferable to the best existing account of them, that offered by Michael Lynch. (shrink)

I argue that racism is essentially a civic character trait: to be a racist is to have a character that rationally reflects racial supremacist sociopolitical values. As with moral vice accounts of racism, character is my account’s primary evaluative focus: character is directly evaluated as racist, and all other racist things are racist insofar as, and because, they cause, are caused by, express or are otherwise suitably related to racist character. Yet as with political accounts of racism, sociopolitical considerations provide (...) my account’s primary evaluative standard: satisfying the sociopolitical standard of racial supremacy is what makes racist character racist.
