In December 1924 Wolfgang Pauli proposed the idea of an inner degree of freedom of the electron, which he insisted should be thought of as genuinely quantum mechanical in nature. Shortly thereafter Ralph Kronig and, independently, Samuel Goudsmit and George Uhlenbeck took up a less radical stance by suggesting that this degree of freedom somehow corresponded to an inner rotational motion, though it was unclear from the very beginning how literal one was actually supposed to take this picture, (...) since it was immediately recognised that it would very likely lead to serious problems with Special Relativity if the model were to reproduce the electron's values for mass, charge, angular momentum, and magnetic moment. However, probably due to the then overwhelming impression that classical concepts were generally insufficient for the proper description of microscopic phenomena, a more detailed reasoning was never given. In this contribution I shall investigate in some detail what the restrictions on the physical quantities just mentioned are, if they are to be reproduced by rather simple classical models of the electron within the framework of Special Relativity. It turns out that surface stresses play a decisive role and that the question of whether a classical model for the electron does indeed contradict Special Relativity can only be answered on the basis of an exact solution, which has hitherto not been given.

We normally take it for granted that other people will live on after we ourselves have died. Even if we do not believe in a personal afterlife in which we survive our own deaths, we assume that there will be a "collective afterlife" in which humanity survives long after we are gone. Samuel Scheffler maintains that this assumption plays a surprising - indeed astonishing - role in our lives.

We sometimes fail unwittingly to do things that we ought to do. And we are, from time to time, culpable for these unwitting omissions. We provide an outline of a theory of responsibility for unwitting omissions. We emphasize two distinctive ideas: (i) many unwitting omissions can be understood as failures of appropriate vigilance, and; (ii) the sort of self-control implicated in these failures of appropriate vigilance is valuable. We argue that the norms that govern vigilance and the value of self-control (...) explain culpability for unwitting omissions. (shrink)

Samuel J. Kerstein develops a new, broadly Kantian account of the ethical issues that arise when a person treats another merely as a means. He explores how Kantian principles on the dignity of persons shed light on pressing issues in modern bioethics, including the distribution of scarce medical resources and the regulation of markets in organs.

In this paper, we focus on whether and to what extent we judge that people are responsible for the consequences of their forgetfulness. We ran a series of behavioral studies to measure judgments of responsibility for the consequences of forgetfulness. Our results show that we are disposed to hold others responsible for some of their forgetfulness. The level of stress that the forgetful agent is under modulates judgments of responsibility, though the level of care that the agent exhibits toward performing (...) the forgotten action does not. We argue that this result has important implications for a long-running debate about the nature of responsible agency. (shrink)

This paper examines the interplay of semantics and pragmatics within the domain of film. Films are made up of individual shots strung together in sequences over time. Though each shot is disconnected from the next, combinations of shots still convey coherent stories that take place in continuous space and time. How is this possible? The semantic view of film holds that film coherence is achieved in part through a kind of film language, a set of conventions which govern the relationships (...) between shots. In this paper, we develop and defend a new version of the semantic view. We articulate it for a pair of conventions that govern spatial relations between viewpoints. One such rule is already well-known; sometimes called the "180° Rule," we term it the X-Constraint; to this we add a previously unrecorded rule, the T-Constraint. As we show, both have the effect, in different ways, of limiting the way that viewpoint can shift through space from shot to shot over the course of a film sequence. Such constraints, we contend, are analogous to relations of discourse coherence that are widely recognized in the linguistic domain. If film is to have a language, it is a language made up of rules like these. (shrink)

Most democratic theorists agree that concentrations of wealth and power tend to distort the functioning of democracy and ought to be countered wherever possible. Deliberative democrats are no exception: though not its only potential value, the capacity of deliberation to ‘neutralise power’ is often regarded as ‘fundamental’ to deliberative theory. Power may be neutralised, according to many deliberative democrats, if citizens can be induced to commit more fully to the deliberative resolution of common problems. If they do, they will be (...) unable to get away with inconsistencies and bad or private reasons, thereby mitigating the illegitimate influence of power. I argue, however, that the means by which power inflects political disagreement is far more subtle than this model suggests and cannot be countered so simply. As a wealth of recent research in political psychology demonstrates, human beings persistently exhibit ‘motivated reasoning’, meaning that even when we are sincerely committed to the deliberative resolution of common problems, and even when we are exposed to the same reasons and evidence, we still disagree strongly about what ‘fair cooperation’ entails. Motivated reasoning can be counteracted, but only under exceptional circumstances such as those that enable modern science, which cannot be reliably replicated in our society at large. My analysis suggests that in democratic politics – which rules out the kind of anti-democratic practices available to scientists – we should not expect deliberation to reliably neutralise power.

Actors, undercover investigators, and readers of fiction sometimes report “losing themselves” in the characters they imitate or read about. They speak of “taking on” or “assuming” the beliefs, thoughts, and feelings of someone else. I offer an account of this strange but familiar phenomenon—what I call imaginative transportation.

We offer a framework for organizing the literature regarding the debates revolving around infinite idealizations in science, and a short summary of the contributions to this special issue.

It is plausible that the models of our scientific theories correspond to possibilities. But exactly which models of which scientific theories stand in this correspondence? The answers to this question hinted at so far in the literature are too restrictive: they don't support the idea that the models of many of our best scientific theories correspond to physical possibilities. The paper thus provides a novel proposal for guiding belief about physical possibilities based on physics. The proposal draws on the notion (...) of an effective theory: a theory that applies very well to a particular, restricted domain. We argue that it is the models of effective theories that we should believe correspond, at least in part, to physical possibilities. It is thus effective theories that should guide modal reasoning in science. (shrink)

The Generality Problem is widely recognized to be a serious problem for reliabilist theories of justification. James R. Beebe's Statistical Solution is one of only a handful of attempted solutions that has garnered serious attention in the literature. In their recent response to Beebe, Julien Dutant and Erik J. Olsson successfully refute Beebe's Statistical Solution. This paper presents a New Statistical Solution that countenances Dutant and Olsson's objections, dodges the serious problems that trouble rival solutions, and retains the theoretical virtues (...) that made Beebe's solution so attractive in the first place. There indeed exists a principled, rigorous, conceptually sparse, and plausible solution to the Generality Problem: it is the New Statistical Solution. (shrink)

In light of Jewish tradition and the metaphysics of time, we argue that God can and will change the past. The argument makes for a new answer to the problem of evil and a new theory of atonement.

In his discussion of the duty of benevolence in §27 of the Metaphysics of Morals, Kant argues that agents have no obligation to promote their own happiness, for ‘this happens unavoidably’ (MS, AA 6:451). In this paper I argue that Kant should not have said this. I argue that Kant should have conceded that agents do have an obligation to promote their own happiness.

According to the Reasoning View about normative reasons, facts about normative reasons for action can be understood in terms of facts about the norms of practical reasoning. I argue that this view is subject to an overlooked class of counterexamples, familiar from debates about Subjectivist theories of normative reasons. Strikingly, the standard strategy Subjectivists have used to respond to this problem cannot be adapted to the Reasoning View. I think there is a solution to this problem, however. I argue that (...) the norms of practical reasoning, like the norms of theoretical reasoning, are characteristically defeasible, in a sense I make precise. Recognizing this property of those norms makes space for a solution to the problem. The resulting view is in a way analogous to the familiar defeasibility theory of knowledge, but it avoids a standard objection to that theory. (shrink)

In this article, we describe four theoretical and methodological problems that have impeded implicit attitude research and the popular understanding of its findings. The problems all revolve around assumptions made about the relationships among measures, constructs, cognitive processes, and features of processing. These assumptions have confused our understandings of exactly what we are measuring, the processes that produce implicit evaluations, the meaning of differences in implicit evaluations across people and contexts, the meaning of changes in implicit evaluations in response to (...) intervention, and how implicit evaluations predict behavior. We describe formal modeling as one means to address these problems, and provide illustrative examples. Clarifying these issues has important implications for our understanding of who has particular implicit evaluations and why, when those evaluations are likely to be particularly problematic, how we might best try to change them, and what interventions are best suited to minimize the effects of implicit evaluations on behavior.

I describe and motivate Rational Internalism, a principle concerning the relationship between motivating reasons (which explain actions) and normative reasons (which justify actions). I use this principle to construct a novel argument against Objectivist theories of normative reasons, which hold that facts about normative reasons can be analyzed in terms of an independently specified class of normative or evaluative facts. I then argue for an alternative theory of normative reasons, the Reasoning View, which is consistent with both Rational Internalism and (...) one standard motivation for Objectivism. (shrink)

Spinoza studies have seen a renaissance of interest in his views on modality, from which considerable disagreement has emerged about Spinoza's modal commitments. Much of this disagreement stems from larger interpretive disagreements about Spinoza's metaphysics. After a brief introduction, this SEP article begins with Spinoza's views on the distribution of modal properties, which quickly leads the heart of Spinoza's metaphysics, intersecting his views on causation, inherence, God, ontological plenitude and the principle of sufficient reason. Although the question of whether Spinoza (...) was a necessitarian is the predominant topic of discussion in the recent secondary literature on Spinoza's modal views, Spinoza also sketches interesting accounts of the nature of modality and the ground of modality that shed fresh light on his modal commitments. Though understudied by recent interpreters, these latter topics were of interest to Spinoza's peers and remain vibrant research questions in contemporary metaphysics of modality. (shrink)

Reading Foucault’s work on power and subjectivity alongside “developmentalist” approaches to evolutionary biology, this article endorses poststructuralist critiques of political ideals grounded in the value of subjective agency. Many political theorists embrace such critiques, of course, but those who do are often skeptical of liberal democracy, and even of normative theory itself. By contrast, those who are left to theorize liberal democracy tend to reject or ignore poststructuralist insights, and have continued to employ dubious ontological assumptions regarding human agents. Against (...) both groups, I argue that Foucault’s poststructuralism must be taken seriously, but that it is ultimately consistent with normative theory and liberal democracy. Linking poststructuralist attempts to transcend the dichotomy between agency and structure with recent efforts by evolutionary theorists to dissolve a similarly stubborn opposition between nature and nurture, I develop an anti-essentialist account of human nature and agency that vindicates poststructuralist criticism while enabling a novel defense of liberal democracy.

Should the idea of economic man-the amoral and self-interested Homo economicus-determine how we expect people to respond to monetary rewards, punishments, and other incentives? Samuel Bowles answers with a resounding "no." Policies that follow from this paradigm, he shows, may "crowd out" ethical and generous motives and thus backfire. But incentives per se are not really the culprit. Bowles shows that crowding out occurs when the message conveyed by fines and rewards is that self-interest is expected, that the employer (...) thinks the workforce is lazy, or that the citizen cannot otherwise be trusted to contribute to the public good. Using historical and recent case studies as well as behavioral experiments, Bowles shows how well-designed incentives can crowd in the civic motives on which good governance depends. (shrink)

This morning I intended to get out of bed when my alarm went off. Hearing my alarm, I formed the intention to get up now. Yet, for a time, I remained in bed, irrationally lazy. It seems I irrationally failed to execute my intention. Such cases of execution failure pose a challenge for Mentalists about rationality, who believe that facts about rationality supervene on facts about the mind. For, this morning, my mind was in order; it was my action that (...) apparently made me irrational. What, then, should Mentalists say about the phenomenon of execution failure? The phenomenon of execution failure, and the puzzle it raises for Mentalists, have rarely been discussed. This paper addresses the puzzle in two parts. First, it argues that execution failure is a real phenomenon. It is possible for agents to irrationally fail to act on their present-directed intentions. It follows that Mentalists in the philosophy of action must solve the puzzle of explaining what is irrational about cases of execution failure. Second, this paper begins the search for such a solution. It considers six possible resolutions to the puzzle, arguing that none is obviously the most attractive. These resolutions include a requirement of overall conative consistency, an appeal to the norm of intention consistency, a form of Volitionalism, an appeal to factive mental states, and a proposal due to Garrett Cullity, and a novel requirement of proper functioning.

Samuel R. Buss and Aleksandar Ignjatović. Unprovability of Consistency Statements in Fragments of Bounded Arithmetic.

In this two-part series, I explore some of the most important and influential interpretations of Spinoza as an idealist. In this second part, I turn to more recent idealistic interpretations of Spinoza, including the important British idealist school (including Pollock, Martineau, Joachim, and John Caird) at the turn of the 20th century to a very recent and important kind of idealist reading found in the work of Michael Della Rocca.

What does it mean for a hypothesis to be ad hoc? One prominent account has it that ad hoc hypotheses have no independent empirical support. Others have viewed ad hoc judgements as subjective. Here I critically review both of these views and defend my own Coherentist Conception of Ad hocness by working out its conceptual and descriptive attractions.

In recent years, some have claimed that a Darwinian perspective will revolutionize the study of human society and culture. This project is viewed with disdain and suspicion, on the other hand, by many practicing social scientists. This article seeks to clear the air in this heated debate by dissociating two claims that are too often assumed to be inseparable. The first is the ‘ontological’ claim that Darwinian principles apply, at some level of abstraction, to human society and culture. The second (...) is the more ‘pragmatic’ claim that this observation necessitates substantial changes in the practices of social scientists. Even if some version of the first claim is true, I argue – which I believe is quite likely – the second does not follow. This observation ought to chasten the most overzealous advocates of Darwinian social science, as well as softening the instinctive resistance of many social scientists and historians to the genuine insights enabled by a Darwinian approach. The conclusion discusses these insights, the most important of which is a methodological prescription for normative theory. (shrink)

If one is interested in reasoning counterfactually within a physical theory, one cannot adequately use the standard possible world semantics. As developed by Lewis and others, this semantics depends on entertaining possible worlds with miracles, worlds in which laws of nature, as described by physical theory, are violated. Van Fraassen suggested instead to use the models of a theory as worlds, but gave up on determining the needed comparative similarity relation for the semantics objectively. I present a third way, in (...) which this similarity relation is determined from properties of the models contextually relevant to the truth of the counterfactual under evaluation. After illustrating this with a simple example from thermodynamics, I draw some implications for future work, including a renewed possibility for a viable deflationary account of laws of nature.

This book examines the evidential status and use of linguistic intuitions, a topic that has seen increased interest in recent years. Linguists use native speakers' intuitions - such as whether or not an utterance sounds acceptable - as evidence for theories about language, but this approach is not uncontroversial. The two parts of this volume draw on the most recent work in both philosophy and linguistics to explore the two major issues at the heart of the debate. Chapters in the (...) first part address the 'justification question', critically analysing and evaluating the theoretical rationale for the evidential use of linguistic intuitions. The second part discusses recent developments in the domain of experimental syntax, focusing on the question of whether formal and systematic models of gathering intuitions are epistemically and methodologically superior to the informal methods that have traditionally been used. -/- The volume provides valuable insights into whether and how linguistic intuitions can be used in theorizing about language, and will be of interest to graduate students and researchers in linguistics, philosophy, and cognitive science.

This paper examines the consequences of a culture of “personal ethics” when using new methodologies, such as the use of social media sites as a source of data for research. Using SM research as an example, this paper explores the practices of a number of actors and researchers within the “Ethics Ecosystem” which as a network governs ethically responsible research behaviour. In the case of SM research, the ethical use of this data is currently in dispute, as even though it (...) is seemingly publically available, concerns relating to privacy, vulnerability, potential harm and consent blur the lines of responsible ethical research behaviour. The findings point to the dominance of a personal, bottom-up, researcher-led, ‘ethical barometer’ for making decisions regarding the permissibility of using SM data. We show that the use of different barometers by different researchers can lead to wide disparities in ethical practice - disparities which are compounded by the lack of firm guidelines for responsible practice of SM research. This has widespread consequences on the development of shared norms and understandings at all levels, and by all actors within the Ethics Ecosystem, and risks inconsistencies in their approaches to ethical decision-making. This paper argues that this governance of ethical behaviour by individual researchers perpetuates a negative cycle of academic practice that is dependent on subjective judgements by researchers themselves, rather than governed by more formalised academic institutions such as the research ethics committee and funding council guidelines.

When considering potential solutions to meaning-scepticism, Kripke (1982) did not consider a causal-theoretic approach. Kusch (2006) has argued that this is due to the qua-problem. I consider Kusch’s criticism of Maddy (1984) and McGinn (1984) before offering a different way to solve the qua-problem, one that is not susceptible to sceptical attack. If this solution is successful, at least one barrier to using a causal theory to refute Kripke’s scepticism is removed.

In this paper, I examine global public reason as a method of justifying a global state. Ultimately, I conclude that global public reason fails to justify a global state. This is the case, because global public reason faces an unwinnable dilemma. The global public reason theorist must endorse either a hypothetical theory of consent or an actual theory of consent; if she endorses a theory of hypothetical consent, then she fails to justify her principles; and if she endorses a theory (...) of actual consent, her theory will lead to a highly unstable political system. On either side of the dilemma, global public reason faces untenable implications. Although similar criticisms have been advanced against domestic public reason, my argument is not repeating points made before me. My argument is new, in that it raises these objections specifically against global public reason, and in that it shows how, due to increased diversity of belief in the global arena, these problems are more pressing for global public reason than they are for domestic public reason.

The physicist Richard Gott defends the Copernican principle, which claims that when we have no information about our position along a given dimension among a group of observers, we should consider ourselves to be randomly located among those observers in respect to that dimension. First, I apply Copernican reasoning to the distribution of evil in the universe. I then contend that evidence for intelligent extraterrestrial life strengthens four important versions of the argument from evil. I remain neutral regarding whether this (...) result is a reductio of these arguments from evil or the statement of a genuine evidential relationship. (shrink)

Jennifer Saul argues that the evidence from the literature on implicit biases entails a form of skepticism. In this paper, I argue that Saul faces a dilemma: her argument is either self-defeating, or it does not yield a skeptical conclusion. For Saul, both results are unacceptable; thus, her argument fails.

My goal in this paper is to show that it is not the case that positive duties can be derived from Kant’s so-called universalizability tests. I begin by explaining in detail what I mean by this and distinguishing it from a few things that I am not doing in this paper. After that, I confront the idea of a maxim contradictory, a concept that is advanced by many com- mentators in the attempt to derive positive duties from the universalizability tests. (...) I ex- plain what a maxim contradictory is and how the concept is used to derive positive duties. Then I argue that the notion of a maxim contradictory presupposes an objectionable form of maxim realism. I move from there to the idea of a maxim contrary and the deliberative field. These two ideas are used in tandem by commentators who do not appeal to maxim contradictories. I explain how these concepts are used to derive positive duties and then I argue that there is a systematic error in the derivations that enables one to see that they cannot work. (shrink)

Suppose that a young athlete has just become quadriplegic. He expects to live several more decades, but out of self‐interest he autonomously chooses to engage in physician‐assisted suicide (PAS) or voluntary active euthanasia (VAE). Some of us are unsure whether he or his physician would be acting rightly in ending his life. One basis for such doubt is the notion that persons have dignity in a Kantian sense. This paper probes responses that David Velleman and Frances Kamm have suggested to (...) the question of whether participating in PAS or VAE to benefit oneself, as the young man might, respects the dignity of persons, specified in an orthodox Kantian way. Velleman claims that it does not, while Kamm insists that, in certain circumstances, it does. I argue against Kamm's position. I go on to contend that while orthodox Kantianism might provide a basis for moral concern regarding the case of the young quadriplegic, it suffers from two serious shortcomings. First, it implies that terminally ill patients are wrong to request VAE or engage in PAS to avoid intense suffering, at least when this suffering has not yet overwhelmed their reason. Second, orthodox Kantianism implies that it is wrong for physicians to withdraw such patients from life‐sustaining treatments, even if they request it. To remedy these shortcomings, I sketch an unorthodox Kantian account of respect for the dignity of persons. This account promises to capture the idea that it would be morally problematic for doctors to help the young quadriplegic to die, but to avoid the shortcomings of an orthodox Kantian account.

In this paper, I argue that sentences that contain ‘omission’ tokens that appear to function as singular terms are meaningful while maintaining the view that omissions are nothing at all or mere absences. I take omissions to be fictional entities and claim that the way in which sentences about fictional characters are true parallels the way in which sentences about omissions are true. I develop a pragmatic account of fictional reference and argue that my fictionalist account of omissions implies a (...) plausible account of the metaphysics of omissions. (shrink)

In the Laws, Plato argues that the legislator should attempt to persuade people to voluntarily obey the laws. This persuasion is accomplished through use of legislative preludes. Preludes (also called preambles) are short arguments written into the legal code, which precede laws and give reasons to follow them. In this paper, I argue that Plato’s use of persuasive preludes shows that he endorses the core features of a public reason theory of political justification. Many philosophers argue that Plato’s political philosophy (...) is deeply at odds with contemporary liberal political philosophy. While Plato certainly does not affirm (and even rejects) some of the main features of liberalism, if it could be shown that he endorses some account of public reason (which is a liberal idea to its core), this would suggest that there is more in common between Plato and liberalism than many philosophers think. Furthermore, if combined with the work of philosophers, like C.C.W. Taylor, this could form a cumulative case against those who argue that there is little in common between Plato’s political philosophy and liberalism. In short, by showing that Plato endorses the core features of public reason, I endeavor to show that there is more in common between Plato and liberalism than is often thought. (shrink)

In 1827, Lady Mary Shepherd published Essays on the Perception of an External Universe, which offers both an argument for the existence of a world of external bodies existing outside our minds and a criticism of Berkeley's argument for idealism in A Treatise Concerning the Principles of Human Knowledge. In this paper, I evaluate Margaret Atherton's criticisms of Shepherd's case against Berkeley, and provide reasons for thinking that, although Shepherd's particular criticisms of Berkeley do not succeed, she correctly identifies an (...) important problem to which Berkeley's reasoning is subject.

Work is on one side a central arena of self-making, self-understanding, and self-development, and on the other a deep threat to our flourishing. My question is: what kind of work is good for human beings, and what kind bad? I first characterise work as necessary productive activity. My answer to my question then develops a perfectionist account of the human good: the good is the full development and expression of human potentials and capacities; this development and expression happens over a (...) lifetime through appropriate practice. Work is thus a problem of human development, and I address that problem by considering three central human capacities: that we are passionate choosers, skilled makers, and social negotiators. For each, I ask: what does this capacity need from our work if it is to develop towards full and flourishing expression? Answering that question leads to a three-part account of good work as requiring: a distinctive kind of pleasure, involving both unselfconscious flow and supervisory self-attention; skill, which I describe via the ideal of craft; and democracy, which I define as a form of life in which each is able to develop and use both expressive and receptive capacities.
