Most philosophers find it puzzling how beliefs could wrong, and this leads them to conclude that they do not. So there is much philosophical work to be done in sorting out whether I am right to say that they do, as well as how this could be so. But in this paper I will take for granted that beliefs can wrong, and ask instead when beliefs wrong. My answer will be that beliefs wrong when they falsely diminish. This answer has (...) three parts: that beliefs wrong only when they are false, that beliefs wrong only when they diminish, and that false diminishment is sufficient for wronging. I will seek to elaborate on and defend all three of these claims, but it is the first to which I will give the most attention. (shrink)

It is now generally understood that constraints play an important role in commonsense moral thinking and generally accepted that they cannot be accommodated by ordinary, traditional consequentialism. Some have seen this as the most conclusive evidence that consequentialism is hopelessly wrong,1 while others have seen it as the most conclusive evidence that moral common sense is hopelessly paradoxical.2 Fortunately, or so it is widely thought, in the last twenty-five years a new research program, that of Agent-Relative Teleology, has come to (...) the rescue on all sides. While consequentialism says that every agent ought always to do that action that will bring about the most good, according to Agent- Relative Teleology. (shrink)

Mark Eli Kalderon presents an original study of perception, taking as its starting point a puzzle in Empedocles' theory of vision: if perception is a mode of material assimilation, how can we perceive colors at a distance? Kalderon argues that the theory of perception offered by Aristotle in answer to the puzzle is both attractive and defensible.

The debate over the meanings of indexical expressions has relied heavily on the method of counterexamples. This paper challenges that method by showing that purported counterexamples can often be explained away by appeal to perspective shifts. For these counterexamples to establish anything about indexical reference, we must identify the conditions under which theorists can legitimately appeal to perspective shifts. Some tests for semantic content are considered and it is argued that none of them can tell us when appeal to perspective (...) shift is admissible. The paper then considers how we should proceed if we become convinced that there is no way to identify the content of indexical expressions, offering reasons in favour of a nihilist conception of character over an epistemicist or pluralist conception.

Scientists often adjust their significance threshold during null hypothesis significance testing in order to take into account multiple testing and multiple comparisons. This alpha adjustment has become particularly relevant in the context of the replication crisis in science. The present article considers the conditions in which this alpha adjustment is appropriate and the conditions in which it is inappropriate. A distinction is drawn between three types of multiple testing: disjunction testing, conjunction testing, and individual testing. It is argued that alpha (...) adjustment is only appropriate in the case of disjunction testing, in which at least one test result must be significant in order to reject the associated joint null hypothesis. Alpha adjustment is inappropriate in the case of conjunction testing, in which all relevant results must be significant in order to reject the joint null hypothesis. Alpha adjustment is also inappropriate in the case of individual testing, in which each individual result must be significant in order to reject each associated individual null hypothesis. The conditions under which each of these three types of multiple testing is warranted are examined. It is concluded that researchers should not automatically assume that alpha adjustment is necessary during multiple testing. Illustrations are provided in relation to joint studywise hypotheses and joint multiway ANOVAwise hypotheses. (shrink)

In his groundbreaking book, Thin Objects, Linnebo (2018) argues for an account of neo-Fregean abstraction principles and thin existence that does not rely on analyticity or conceptual rules. It instead relies on a metaphysical notion he calls “sufficiency”. In this short discussion, I defend the analytic or conceptual rule account of thin existence.

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors We (...) Live By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

Hume argues that we succumb to the vice of prejudice when we fail to correct negative generalizations about social groups in the face of counter-evidence. We are blameworthy for these biases, moreover, even if they are unavoidable. Hume’s theory of doxastic responsibility entails that his own racial prejudices are deserving of condemnation. In contrast, contemporary vice epistemologists are more inclined to absolve agents of culpability for prejudices beyond their control.

In his contribution, Mark Alfano lays out a new (to virtue theory) naturalistic way of determining what the virtues are, what it would take for them to be realized, and what it would take for them to be at least possible. This method is derived in large part from David Lewis’s development of Frank Ramsey’s method of implicit definition. The basic idea is to define a set of terms not individually but in tandem. This is accomplished by assembling all (...) and only the common sense platitudes that involve them (e.g., typically, people want to be virtuous), conjoining those platitudes, and replacing the terms in question by existentially quantified variables. If the resulting sentence is satisfied, then whatever satisfies are the virtues. If it isn’t satisfied, there are a couple of options. First, one could just admit defeat by saying that people can’t be virtuous. More plausibly, one could weaken the conjunction by dropping a small number of the platitudes from it (and potentially adding some others). Alfano suggests that the most attractive way to do this is by dropping the platitudes that deal with cross-situational consistency and replacing them with platitudes that involve social construction: basically, people are virtuous (when they are) at least in part because other people signal their expectations of virtuous conduct, which induces virtuous conduct, which in turn induces further signals of expected virtuous conduct, and so on.

Keepsakes are nostalgic objects par excellence. We value keepsakes because they prompt nostalgic memories of the past. But perhaps more importantly, we also value them because they afford a feeling of contact with that which they remind us of. Drawing on work in philosophy and psychology, this chapter aims to give an account of the nature and value of keepsakes as nostalgic objects. Keepsakes, it argues, are objects that bear a material continuity with some person, event, or place from one’s (...) past to which one has a personal attachment. To understand the distinctive experiential value of keepsakes as nostalgic objects, however, the chapter argues that we need to invoke the imagination. Keepsakes manifest the presence of the past by prompting one to imaginatively project what a keepsake is historically connected with onto the object as one experiences it in the present. (shrink)

For years now, unionization has been under vigorous attack. Membership has been steadily declining, and with it union bargaining power. As a result, unions may soon lose their ability to protect workers from economic and personal abuse, as well as their significance as a political force. In the Name of Liberty responds to this worrying state of affairs by presenting a new argument for unionization, one that derives an argument for universal unionization in both the private and public sector from (...) concepts of liberty that we already accept. In short, In the Name of Liberty reclaims the argument for liberty from the political right, and shows how liberty not only requires the unionization of every workplace as a matter of background justice, but also supports a wide variety of other progressive policies.

In this paper, I describe some of what I take to be the more interesting features of friendship, then explore the extent to which other virtues can be reconstructed as sharing those features. I use trustworthiness as my example throughout, but I think that other virtues such as generosity & gratitude, pride & respect, and the producer’s & consumer’s sense of humor can also be analyzed with this model. The aim of the paper is not to demonstrate that all moral (...) virtues are exactly like friendship in all important respects, but rather to articulate a fruitful model in which to explore the virtues. Section 2 explores the relational nature of friendship, drawing on Aristotle’s discussion of friendship in the Nicomachean Ethics. Section 3 catalogues four motivations for taking seriously the friendship model of virtue. Section 4 applies the friendship model in depth to the virtue of trustworthiness. (shrink)

Mechanistic explanations satisfy widely held norms of explanation: the ability to manipulate and answer counterfactual questions about the explanandum phenomenon. A currently debated issue is whether any nonmechanistic explanations can satisfy these explanatory norms. Weiskopf argues that the models of object recognition and categorization, JIM, SUSTAIN, and ALCOVE, are not mechanistic yet satisfy these norms of explanation. In this article I argue that these models are mechanism sketches. My argument applies recent research using model-based functional magnetic resonance imaging, a novel (...) neuroimaging method whose significance for current debates on psychological models and mechanistic explanation has yet to be explored.

Virtues are dispositions that make their bearers admirable. Dispositions can be studied scientifically by systematically varying whether their alleged bearers are in (or take themselves to be in) the dispositions' eliciting conditions. In recent decades, empirically-minded philosophers looked to social and personality psychology to study the extent to which ordinary humans embody dispositions traditionally considered admirable in the Aristotelian tradition. This led some to conclude that virtues are not attainable ideals, and that we should focus our ethical reflection and efforts (...) more on jerry-rigging our environments than on improving our characters. Most virtue ethicists resisted this reorientation. However, much of the scientific evidence on which the controversy was based has failed to replicate, raising the question of how much faith we should place in methodologically suspect studies. In this paper, I assess the state of the debate and recommend best practices for a renewed interdisciplinary investigation of virtues and vices in which philosophical expertise related to conceptualization and theorizing is essentially intertwined with scientific expertise related to operationalization, measurement, and statistics.

Research notes of Mark Pettinelli about cognitive science, cognitive psychology.

This collection of articles is almost all of the psychological writings of Mark Pettinelli.

Nondescriptivist views in many areas of philosophy have long been associated with the commitment that in contrast to other domains of discourse, there are no propositions in their particular domain. For example, the ‘no truth conditions’ theory of conditionals1 is understood as the view that conditionals don’t express propositions, noncognitivist expressivism in metaethics is understood as advocating the view that there are not really moral propositions,2 and expressivism about epistemic modals is thought of as the view that there is no (...) such thing as the proposition that Jack might be at home, over and above the proposition that Jack is at home.3 Of course, it is nearly always acknowledged that advocates of a nondescriptivist theory need not deny that there are conditional, moral, or modal propositions ‘at the end of the day’ – for if they also endorse a deflationary reading of talk about propositions, as famously advocated by Simon Blackburn, then they can employ such deflationary talk just as much as the rest of us. They just don’t appeal to propositions to do any of the work in their theories. Rather, they ‘earn the right’ to talk about propositions.4 It is the aim of this paper to upset this way of thinking about the proper attitude of nondescriptivists toward propositions, and to advocate a more constructive and in some ways more radical alternative on behalf of the nondescriptivist. I will begin by introducing and developing a set of problems that are faced by any nondescriptivist theory which tries to do without propositions. All of these problems are easily solved by any view which postulates propositions across the board, but none of them are solved by merely deflationary talk about propositions – their most promising solutions require propositions to do real theoretical work, and therefore the problems themselves remind us of and illustrate some of the important reasons why it is worth positing propositions in the first place..

Jago uses a Fitch-style argument in an attempt to demonstrate that every truth has a truthmaker. But Trueman shows that there is a parallel argument, this time to the conclusion that no truth has a truthmaker. Since we cannot accept both, we must ditch at least one Fitch. But which? Keywords: Truth, truthmaking, truthmaker maximalism, Fitch paradox, Robert Trueman.

This is an overview of the main themes and theses of _Reasons First_ for a book symposium, and intended to be read alongside the other contributions to that symposium.

This paper brings together two erstwhile distinct strands of philosophical inquiry: the extended mind hypothesis and the situationist challenge to virtue theory. According to proponents of the extended mind hypothesis, the vehicles of at least some mental states (beliefs, desires, emotions) are not located solely within the confines of the nervous system (central or peripheral) or even the skin of the agent whose states they are. When external props, tools, and other systems are suitably integrated into the functional apparatus of (...) the agent, they are partial bearers of her cognitions, motivations, memories, and so on. According to proponents of the situationist challenge to virtue theory, dispositions located solely within the confines of the nervous system (central or peripheral) or even the skin of the agent to whom they are attributed typically do not meet the normative standards associated with either virtue or vice (moral, epistemic, or otherwise) because they are too susceptible to moderating external variables, such as mood modulators, ambient sensibilia, and social expectation signaling. We here draw on both of these literatures to formulate two novel views – the embedded and extended character hypotheses – according to which the vehicles of not just mental states but longer-lasting, wider-ranging, and normatively-evaluable agentic dispositions are sometimes located partially beyond the confines of the agent’s skin.

I propose an apparatus for handling intrasentential change in context. The standard approach has problems with sentences with multiple occurrences of the same demonstrative or indexical. My proposal involves the idea that contexts can be complex. Complex contexts are built out of (“simple”) Kaplanian contexts by ordered n-tupling. With these we can revise the clauses of Kaplan’s Logic of Demonstratives so that each part of a sentence is taken in a different component of a complex context. I consider other applications (...) of the framework: to agentially distributed utterances (ones made partly by one speaker and partly by another); to an account of scare-quoting; and to an account of a binding-like phenomenon that avoids what Kit Fine calls “the antinomy of the variable.”.

Orwell’s views on the nature of free speech are significantly more complex than is often recognized. This paper examines what he had to say about freedom of speech and intellectual freedom. It seeks to provide a philosophical analysis of his understanding and use of these concepts and to address some apparent tensions in his thought. In so doing, the paper identifies five dominant aspects of Orwell’s account of free speech. He viewed free speech as closely related to intellectual freedom, which (...) he highly valued; he treated free speech as primarily about the ability to say what one believes to be true; he thought that both government and various kinds of private actors posed serious threats to free speech; he believed that free speech required social safeguards, in addition to legal protection; and he recognized that free speech was a right with limits. He wrote little about the freedom of speech for liars. The paper concludes with the observation that he, therefore, left us with a number of crucial questions to discuss and think about for ourselves. (shrink)

Beliefs are concrete particulars containing ideas of properties and notions of things, which also are concrete. The claim made in a belief report is that the agent has a belief (i) whose content is a specific singular proposition, and (ii) which involves certain of the agent's notions and ideas in a certain way. No words in the report stand for the notions and ideas, so they are unarticulated constituents of the report's content (like the relevant place in "it's raining"). The (...) belief puzzles (Hesperus, Cicero, Pierre) involve reports about two different notions. So the analysis gets the puzzling truth values right. (shrink)

Metaethical expressivists claim that we can explain what moral words like ‘wrong’ mean without having to know what they are about – but rather by saying what it is to think that something is wrong – namely, to disapprove of it. Given the close connection between expressivists’ theory of the meaning of moral words and our attitudes of approval and disapproval, expressivists have had a hard time shaking the intuitive charge that theirs is an objectionably subjectivist or mind-dependent view of (...) morality. Expressivism, critics have charged over and again, is committed to the view that what is wrong somehow depends on or at least correlates with the attitudes that we have toward it. Arguments to this effect are sometimes subtle, and sometimes rely on fancy machinery, but they all share a common flaw. They all fail to respect the fundamental idea of expressivism: that ‘stealing is wrong’ bears exactly the same relationship to disapproval of stealing as ‘grass is green’ bears to the belief that grass is green. In this paper I rehearse the motivations for the fundamental idea of expressivism and show how the arguments of Frank Jackson and Philip Pettit [1998], Russ Shafer-Landau [2003], Jussi Suikkanen [2009], and Christopher Peacocke [2004] all fail on this same rock. In part 1 I’ll rehearse the motivation for expressivism – a motivation which directly explains why it does not have subjectivist consequences. Then in each of parts 2-5 I’ll illustrate how each of Jackson and Pettit’s, Peacocke’s, Shafer-Landau’s, and Suikkanen’s arguments work, respectively, and why each of them fails to respect the fundamental parity at the heart of expressivism. Though others have tried before me to explain why expressivism is not committed to any kind of subjectivism or mind-dependence – prominently including Blackburn [1973], [1998], Horgan and Timmons [2006], and, in response to Pettit and Jackson, Dreier [2004] and Smith and Stoljar [2003], the explanation offered in this article is distinguished by its scope and generality..

Popper’s (1983, 2002) philosophy of science has enjoyed something of a renaissance in the wake of the replication crisis, offering a philosophical basis for the ensuing science reform movement. However, adherence to Popper’s approach may also be at least partly responsible for the sense of “crisis” that has developed following multiple unexpected replication failures. In this article, I contrast Popper’s approach with Lakatos’ (1978) approach and a related approach called naïve methodological falsificationism (NMF; Lakatos, 1978). The Popperian approach is powerful (...) because it is based on logical refutation, but its theories are noncausal and, therefore, lacking in scientific value. In contrast, the Lakatosian approach considers causal theories, but it concedes that these theories are not logically refutable. Finally, the NMF approach subjects Lakatosian causal theories to Popperian logical refutations. However, its approach of temporarily accepting a ceteris paribus clause during theory testing may be viewed as scientifically inappropriate, epistemically inconsistent, and “completely redundant” (Lakatos, 1978, p. 40). I conclude that the replication “crisis” makes the most sense in the context of the Popperian and NMF approaches because it is only in these two approaches that replication failures represent logical refutations of theories. In contrast, replication failures are less problematic in the Lakatosian approach because they do not logically refute theories. Indeed, in the Lakatosian approach, replication failures can be legitimately ignored or used to motivate theory development. (shrink)

Propositions play a central role in contemporary semantics. On the Russellian account, propositions are structured entities containing particulars, properties and relations. This contrasts sharply with the sets-of-possible-worlds view of propositions. I’ll discuss how to extend the sets-of-worlds view to accommodate fine-grained hyperintensional contents. When this is done in a satisfactory way, I’ll argue, it makes heavy use of entities very much like Russellian tuples. The two notions of proposition become inter-definable and inter-substitutable: they are not genuinely distinct accounts of how (...) propositions represent what they represent. Semantic theorists may move freely between the two conceptions of what propositions are. Nevertheless, the two approaches give different accounts of the metaphysical nature of propositions. I argue that the sets-of-worlds view provides an adequate account of the nature of propositions, whereas the Russellian view cannot. (shrink)

Doxastic voluntarism is the thesis that our beliefs are subject to voluntary control. While there’s some controversy as to what “voluntary control” amounts to (see 1.2), it’s often understood as direct control: the ability to bring about a state of affairs “just like that,” without having to do anything else. Most of us have direct control over, for instance, bringing to mind an image of a pine tree. Can one, in like fashion, voluntarily bring it about that one believes a (...) specific proposition? Doxastic voluntarists hold that, at least in some circumstances—such as when the evidence is ambiguous—we can. Doxastic involuntarists, in contrast, maintain that we cannot. Some involuntarists hold that the concept of belief itself precludes the possibility of believing voluntarily. Others hold that the impossibility of voluntary belief is a contingent psychological fact. Historically, the issue of doxastic voluntarism has been connected to how many think about religious commitment: a prominent view of faith is that it is a voluntary decision to believe. Furthermore, the issue of voluntarism has also been viewed as having bearing on fundamental questions in epistemology. For example, are epistemic norms duties to believe in certain ways? Are there practical or moral reasons to believe? If the answer to either question is “yes,” it seems some measure of voluntary doxastic control is required. -/- In section 1, we expand on the definition of doxastic voluntarism, and survey various kinds of control (e.g. direct, indirect, long-range) and the doxastic attitudes we might control (e.g. outright belief, withholding, credences). In section 2, we discuss a number of historical views on doxastic voluntarism. In section 3, we survey motivations for rejecting doxastic voluntarism. There are two general strategies: arguments that appeal to psychological considerations, and conceptual arguments regarding the nature of belief. In section 4, we survey five approaches to defending voluntarism: those that appeal to epistemic permissivism, doxastic compatibilism, skepticism, one-off considerations, and non-standard views of belief. In section 5, we cover empirical work on doxastic voluntarism. The last two sections discuss two implications of voluntarism. In section 6, we discuss voluntarism’s implications for the ethics of belief, and in section 7, we discuss issues at the intersection of voluntarism and religious faith. (shrink)

The concepts of placebos and placebo effects refer to extremely diverse phenomena. I recommend dissolving the concepts of placebos and placebo effects into loosely related groups of specific mechanisms, including (potentially among others) expectation-fulfillment, classical conditioning, and attentional-somatic feedback loops. If this approach is on the right track, it has three main implications for the ethics of informed consent. First, because of the expectation-fulfillment mechanism, the process of informing cannot be considered independently from the potential effects of treatment. Obtaining informed (...) consent influences the effects of treatment. This provides support for the authorized concealment and authorized deception paradigms, and perhaps even for outright deceptive placebo use. Second, doctors may easily fail to consider the potential benefits of conditioning, leading them to misjudge the trade-off between beneficence and autonomy. Third, how attentional-somatic feedback loops play out depends not only on the content of the informing process but also on its framing. This suggests a role for libertarian paternalism in clinical practice. (shrink)

Philosophers have come to distinguish between ‘right’ and ‘wrong’ kinds of reasons for belief, intention, and other attitudes. Several theories about the nature of this distinction have been offered, by far the most prevalent of which is the idea that it is, at bottom, the distinction between what are known as ‘object-given’ and ‘state-given’ reasons. This paper argues that the object-given/state-given theory vastly overgeneralizes on a small set of data points, and in particular that any adequate account of the distinction (...) between the ‘right’ and ‘wrong’ kinds of reason must allow state-given reasons to be of the right kind. The paper has three main goals, corresponding to its three main parts. In part 1 I set up the problem by introducing the right-kind/wrong-kind distinction, the object-given/state-given distinction, and the object-given/state-given theory, according to which the former distinction simply amounts to the latter. Part 2 presents the main argument of the paper: I argue against the object-given/state-given theory by showing that all of the earmarks of the ‘right’ and ‘wrong’ kinds of reason apply to reasons not to intend and not to believe, but that these cases can’t be captured by the object-given/state-given theory. Finally, in part 3 I use these arguments to motivate and explore a more general hypothesis about the rightkind/wrong-kind distinction, and explore some of the consequences of rejecting the object-given/stategiven theory.

Can one fully succeed in performing illocutionary acts addressed to others if they do not understand what one is purportedly saying? Can one, for example, tell others something if they do not understand what one supposedly said? It is not uncommon for speech act theorist to claim that one cannot.

Pluralists about coincident entities say that distinct entities may be spatially coincident throughout their entire existence. The most pressing issue they face is the grounding problem. They say that coincident entities may differ in their persistence conditions and in the sortals they fall under. But how can they differ in these ways, given that they share all their microphysical properties? What grounds those differences, if not their microphysical properties? Do those differences depend only on the way we conceptualise those objects? (...) Are they primitive facts about reality? Neither option is pleasant for the pluralist, but what else can she say? To respond to the grounding problem, the pluralist should first tell a story about what material objects are. If that story explains how the modal and sortal properties of objects are grounded, in a way that allows for differences between coincident objects, then she has a response to the problem. That is precisely my aim in this paper. (shrink)

In this paper, I explore the role for anticipated regret in major life decision-making, focusing on how it is employed by realistic decision-makers in a variety of realistic cases. I argue that the most obvious answers to how regret might matter in decision do not make these cases intelligible, but that we can make them intelligible through consideration of the significance of narrative in our own self-understanding.

YouTube has been implicated in the transformation of users into extremists and conspiracy theorists. The alleged mechanism for this radicalizing process is YouTube’s recommender system, which is optimized to amplify and promote clips that users are likely to watch through to the end. YouTube optimizes for watch-through for economic reasons: people who watch a video through to the end are likely to then watch the next recommended video as well, which means that more advertisements can be served to them. This (...) is a seemingly innocuous design choice, but it has a troubling side-effect. Critics of YouTube have alleged that the recommender system tends to recommend extremist content and conspiracy theories, as such videos are especially likely to capture and keep users’ attention. To date, the problem of radicalization via the YouTube recommender system has been a matter of speculation. The current study represents the first systematic, pre-registered attempt to establish whether and to what extent the recommender system tends to promote such content. We begin by contextualizing our study in the framework of technological seduction. Next, we explain our methodology. After that, we present our results, which are consistent with the radicalization hypothesis. Finally, we discuss our findings, as well as directions for future research and recommendations for users, industry, and policy-makers. (shrink)

Several authors have recently endorsed the thesis that there is what has been called pragmatic encroachment on knowledge—in other words, that two people who are in the same situation with respect to truth-related factors may differ in whether they know something, due to a difference in their practical circumstances. This paper aims not to defend this thesis, but to explore how it could be true. What I aim to do, is to show how practical factors could play a role in (...) defeating knowledge by defeating epistemic rationality—the very kind of rationality that is entailed by knowledge, and in which Pascalian considerations do not play any role—even though epistemic rationality consists in having adequate evidence.

This paper is about whether shifts in attention can alter what it is like to think. I begin by taking up the hypothesis that attention structures consciousness into a centre and a periphery, following Watzl's (2014; 2017) understanding of the distinction between the centre and periphery of the field of consciousness. Then I show that introspection leads to divided results about whether attention structures conscious thought into a centre and a periphery -- remarks by Martin (1997) and Phillips (2012) suggest (...) a negative answer, whereas remarks by Maher (1923) and Chudnoff (2013) suggest a positive answer. Lastly, I argue that there is behavioural evidence that lends weight to the 'yes' side of the introspective dispute. My argument makes use of Garavan's (1998) study of forming and maintaining two mental counts at once. (shrink)

Moral theories usually aspire to be explanatory – to tell us why something is wrong, why it is good, or why you ought to do it. So it is worth knowing how moral explanations differ, if they do, from explanations of other things. This paper uncovers a common unarticulated theory about how normative explanations must work – that they must follow what I call the Standard Model. Though the Standard Model Theory has many implications, in this paper I focus primarily (...) on only one. It plays a crucial role in an argument originally due to Cudworth that has been widely held to conclusively establish that voluntaristic ethical theories are incoherent. But if Cudworth’s argument works, then so would similar arguments against many other moral theories. All of these theories therefore need a different model for how normative explanations can work. So I also motivate and sketch one such alternative model. The result enables us to make progress in evaluating the prospects for a successful reductive view about the normative. (shrink)

In “Stakes, Withholding, and Pragmatic Encroachment on Knowledge,” I used a variety of cases, including cases of forced choice, to illustrate my explanation of how and why some pragmatic factors, but not others, can affect whether an agent knows. In his recent contribution, Andy Mueller argues that cases of forced choice actually pose a dilemma for my account. In this paper I reply.

I present an internal problem for David Lewis’s genuine modal realism. My aim is to show that his analysis of modality is inconsistent with his metaphysics. I consider several ways of modifying the Lewisian analysis of modality, but argue that none are successful. I argue that the problem also affects theories related to genuine modal realism, including the stage theory of persistence and modal fictionalism.

Fitting Attitudes accounts of value analogize or equate being good with being desirable, on the premise that ‘desirable’ means not, ‘able to be desired’, as Mill has been accused of mistakenly assuming, but ‘ought to be desired’, or something similar. The appeal of this idea is visible in the critical reaction to Mill, which generally goes along with his equation of ‘good’ with ‘desirable’ and only balks at the second step, and it crosses broad boundaries in terms of philosophers’ other (...) commitments. For example, Fitting Attitudes accounts play a central role both in T.M. Scanlon’s [1998] case against teleology, and in Michael Smith [2003], [unpublished] and Doug Portmore’s [2007] cases for it. And of course they have a long and distinguished history. (shrink)

We can readily identify goal-directed systems and distinguish them from non-goal-directed systems. A woodpecker hunting for grubs is the first, a pendulum returning to rest is the second. But what is it to be a goal-directed system? Perhaps the dominant answer to this question, inspired by systems theories such as cybernetics, is that goal-directed systems are distinguished by their tendency to seek, aim at, or maintain some more-or-less easily identifiable goal. Cybernetics and the like would hold that physical systems subject (...) only to physical laws can exhibit such behavior. If sound, this systems approach to teleology would unify a diverse range of goal-directed phenomena and neatly side-step many traditional bogey-men of teleology, such as anthropomorphism and future causation. Goal-directed phenomena would be a normal feature of the natural causal world that could be described in purely descriptive and quantitative terms, and receive ordinary causal explanations. Thus, the systems approach promises to provide a naturalistic-cum-descriptive account of teleology suitable for use in naturalistic accounts of other phenomena, including the intentionality of mental states and even self-consciousness.

I develop and defend a truthmaker semantics for the relevant logic R. The approach begins with a simple philosophical idea and develops it in various directions, so as to build a technically adequate relevant semantics. The central philosophical idea is that truths are true in virtue of specific states. Developing the idea formally results in a semantics on which truthmakers are relevant to what they make true. A very natural notion of conditionality is added, giving us relevant implication. I then (...) investigate ways to add conjunction, disjunction, and negation; and I discuss how to justify contraposition and excluded middle within a truthmaker semantics. (shrink)
