Gain or omission/termination of loss produces approach; while loss or omission/termination of gain produces withdrawal. Control of approach/withdrawal motivation is distinct from valuation of gain/loss and does not entail learning – making “reward” and “punishment” ambiguous. Approach-withdrawal goal conflict engages a neurally distinct Behavioural Inhibition System, which controls “anxiety” but not “fear”.

Many philosophers argue that the face-value of moral practice provides presumptive support to moral realism. This paper analyses such arguments into three steps. (1) Moral practice has a certain face-value, (2) only realism can vindicate this face value, and (3) the face-value needs vindicating. Two potential problems with such arguments are discussed. The first is taking the relevant face-value to involve explicitly realist commitments; the second is underestimating the power of non-realist strategies to vindicate that face-value. Case studies of each (...) of these errors are presented, drawn from the writings of Shafer-Landau, Brink and McNaughton, and from recent work in experimental metaethics. The paper then considers weak presumptive arguments, according to which both realist and non-realist vindications of moral practice are possible, but the realist vindications are more natural. It is argued that there is no sense of ‘natural’ available that can make these arguments work. The conclusion is that all extant presumptive arguments for moral realism fail. (shrink)

Essays devoted to the work of the late Neil Wilson, Canadian philosopher and contributor to the field of semantic analysis that emerged from the fusion of logic, pragmatism, and ontology. Many of the essays in this volume take their initial inspiration from Wilson's seminal work Substances Without Substrata.

Multiverse Views in set theory advocate the claim that there are many universes of sets, no-one of which is canonical, and have risen to prominence over the last few years. One motivating factor is that such positions are often argued to account very elegantly for technical practice. While there is much discussion of the technical aspects of these views, in this paper I analyse a radical form of Multiversism on largely philosophical grounds. Of particular importance will be an account of (...) reference on the Multiversist conception, and the relativism that it implies. I argue that analysis of this central issue in the Philosophy of Mathematics indicates that Radical Multiversism must be algebraic, and cannot be viewed as an attempt to provide an account of reference without a softening of the position.

Are the objects and events that take place in Virtual Reality genuinely real? Those who answer this question in the affirmative are realists, and those who answer in the negative are irrealists. In this paper we argue against the realist position, as given by Chalmers (2017), and present our own preferred irrealist account of the virtual. We start by disambiguating two potential versions of the realist position—weak and strong— and then go on to argue that neither is plausible. We then (...) introduce a Waltonian variety of ictionalism about the virtual, arguing that this sort of irrealist approach avoids the problems of the realist positions, fits with a unifying theory of representational works, and offers a better account of the phenomenology of engaging in virtual experiences.

Set-theoretic and category-theoretic foundations represent different perspectives on mathematical subject matter. In particular, category-theoretic language focusses on properties that can be determined up to isomorphism within a category, whereas set theory admits of properties determined by the internal structure of the membership relation. Various objections have been raised against this aspect of set theory in the category-theoretic literature. In this article, we advocate a methodological pluralism concerning the two foundational languages, and provide a theory that fruitfully interrelates a `structural' perspective (...) to a set-theoretic one. We present a set-theoretic system that is able to talk about structures more naturally, and argue that it provides an important perspective on plausibly structural properties such as cardinality. We conclude the language of set theory can provide useful information about the notion of mathematical structure. (shrink)

Awarding rights to rivers, forests, and other environmental entities (EEs) is a new and increasingly popular approach to environmental protection. The distinctive feature of such rights of nature (RoN) legislation is that direct duties are owed to the EEs. This paper presents a novel rebuttal of the strongest argument against RoN: the no interest argument. The crux of this argument is that because EEs are not sentient, they cannot possess the kinds of interests necessary to ground direct duties. Therefore, they (...) cannot be legitimate rights-bearers. After considering and rejecting standard responses to this argument, the paper challenges its fundamental assumption: that rights-correlative duties must be grounded in the interests of the rights-bearer. The paper then presents the RoN critic with a dilemma. The critic must either accept that EEs are legitimate rights-bearers, or delegitimise many well-established rights-bearers along with EEs. Either way, the no interest argument loses its force. (shrink)

In recent years the distinction between agent-relative and agent-neutral reasons has been taken by many to play a key role in distinguishing deontology from consequentialism. It is central to all universalist consequentialist theories that value is determined impersonally; the real value of any state of affairs does not depend on the point of view of the agent. No reference, therefore, to the agent or to his or her position in the world need enter into a consequentialist understanding of what makes (...) an action right or wrong or morally permissible. Consequentialism thus provides an agent-neutral account of both the right and the good. (shrink)

Eco-labels emphasize information disclosure as a tool to induce environmentally friendly behaviors by both firms and consumers. The goal of eco-labels is to reduce information asymmetry between producers and consumers over the environmental attributes of a product or service. However, by focusing on this information asymmetry, rather than on how the label meets consumer needs, eco-labels may send irrelevant, confusing, or even detrimental messages to consumers. In this article, the authors investigate how the environmental signal of eco-labels interacts with product (...) characteristics such as brand, quality, and price. In a discrete choice experiment, the authors examine consumer response to two similar eco-labels for wine, one associated with a quality reduction and the other not. The results show that respondents preferred both eco-labeled wines over otherwise identical conventional counterparts when the price was lower and the wine was from a lower quality region. However, they preferred conventional, more expensive wine from a high-quality region. This preference indicates that respondents not only obtain some warm glow value from eco-labeled wine but also possibly interpret eco-labeling as a signal of lower quality. This relationship held across both types of eco-labels, meaning that consumers did not understand the difference between them. This research contributes to the literature on information disclosure policies by highlighting important elements for effective eco-labels. These elements include consumer awareness and understanding of the eco-label, and consumer willingness to pay for an eco-labeled product. The results emphasize the need to create eco-labels that communicate clearly both the environmental attributes and the private benefits associated with them. (shrink)

The rules for Core Logic are stated, and various important results about the system are summarized. We describe its relationship to other systems, such as Classical Logic, Intuitionistic Logic, Minimal Logic, and the Anderson–Belnap relevance logicR. A precise, positive explication is offered of what it is for the premises of a proof to connect relevantly with its conclusion. This characterization exploits the notion of positive and negative occurrences of atoms in sentences. It is shown that all Core proofs are relevant (...) in this precisely defined sense. We survey extant results about variable-sharing in rival systems of relevance logic, and find that the variable-sharing conditions established for them are weaker than the one established here for Core Logic (and for its classical extension). Proponents of other systems of relevance logic (such asRand its subsystems) are challenged to formulate a stronger variable-sharing condition, and to prove thatRor any of its subsystems satisfies it, but that Core Logic does not. We give reasons for pessimism about the prospects for meeting this challenge. (shrink)

This book introduces the reader to ethics by examining a current and important debate. During the last fifty years the orthodox position in ethics has been a broadly non-cognitivist one: since there are no moral facts, moral remarks are best understood, not as attempting to describe the world, but as having some other function - such as expressing the attitudes or preferences of the speaker. In recent years this position has been increasingly challenged by moral realists who maintain that there (...) are moral facts; there is a truth of the matter in ethics, which is independent of our views, and which we seek to discover. Unfortunately much of this interesting debate found in the work of McDowell, Wiggins, Putnam, Blackburn and others is not easily accessible to undergraduates. McNaughton presents many of the major issues in ethics by way of a clear exposition of both sides of this argument and assumes no prior knowledge of philosophy. Topics discussed include: moral observation, moral motivation, amoralism and wickedness, moral weakness, cultural relativism and utilitarianism. The book concludes that a convincing case can be made out for a radical form of moral realism in which moral virtue is found, not in the following of correct moral principles, but rather in the development of moral sensitivity. Moral Vision is a clear and engaged introduction to an important, and often troubling, debate. (shrink)

This chapter proposes a novel form of deontology that, while it contrasts with consequentialism in defending duties of special relationship and options, is allied with consequentialism in denying that there are moral constraints. It devotes considerable attention to distinguishing between various consequentialist doctrines, and the distinction between them and deontology. The distinction between agent-relativity and agent-neutrality plays a crucial role here. It also discusses and rejects contractualism. The same applies to particularism in its most radical form: despite the sympathy for (...) the particularist’s skepticism concerning strict moral principles, it is argued that there are principles of a weaker, Rossian form.

Simon Blackburn can be seen as challenging those committed to sui generis moral facts to explain the supervenience of the moral on the descriptive. We (like perhaps Derek Parfit) hold that normative facts in general are sui generis. We also hold that the normative supervenes on the descriptive, and we here endeavour to answer the generalization of Blackburn's challenge. In the course of pursuing this answer, we suggest that Frank Jackson's descriptivism rests on a conception of properties inappropriate to discussions (...) of normativity, and we see reason to reject descriptivism generally. We also discuss the views of David Brink, Jonathan Dancy and Bernard Williams in this area. (shrink)

One of the major contributions which Christopher Hookway has made to pragmatist epistemology is a critical exploration of the role that affective dispositions play in inquiry. According to Hookway, a well-functioning rational inquirer must rely upon a set of pre-reflective and affective dispositions which are not themselves fully available to rational evaluation. Despite their pre-reflective nature, on the pragmatist account these affective dispositions provide us with judgments and evaluations which are in many cases more reliable than those provided by explicit (...) rational reflection. -/- This chapter presents and defends Hookway’s account of the epistemic importance of our affective dispositions. The first section presents three roles which affective dispositions play within inquiry. The second section considers the concern that affective dispositions should be considered impositions upon our epistemic agency. In response, Hookway suggests that we must identify with our affective dispositions, and two interpretations of this claim are offered. The third section considers the possibility that the confidence we have in our affective dispositions might be appropriately shaken if we recognize that they are not shared by other inquirers. The chapter concludes by suggesting that Hookway’s position can overcome this worry by developing his notion of critical self-trust in three distinct ways. (shrink)

This Element explores what it means for two theories in physics to be equivalent, and what lessons can be drawn about their structure as a result. It does so through a twofold approach. On the one hand, it provides a synoptic overview of the logical tools that have been employed in recent philosophy of physics to explore these topics: definition, translation, Ramsey sentences, and category theory. On the other, it provides a detailed case study of how these ideas may be (...) applied to understand the dynamical and spatiotemporal structure of Newtonian mechanics - in particular, in light of the symmetries of Newtonian theory. In so doing, it brings together a great deal of exciting recent work in the literature, and is sure to be a valuable companion for all those interested in these topics. (shrink)

This essay presents an ideal for modern Western romantic love.The basic ideas are the following: people want to form a distinctive sort of plural subject with another, what Nozick has called a "We", they want to be loved for properties of certain kinds, and they want this love to establish and sustain a special sort of commitment to them over time.

Given the tremendous proliferation of student plagiarism involving the Internet, the purpose of this study is to determine which theory of ethical reasoning students invoke when defending their transgressions: deontology, utilitarianism, rational self-interest, Machiavellianism, cultural relativism, or situational ethics. Understanding which theory of ethical reasoning students employ is critical, as preemptive steps can be taken by faculty to counteract this reasoning and prevent plagiarism. Additionally, it has been demonstrated that unethical behavior in school can lead to unethical behavior in business; (...) therefore, correcting unethical behavior in school can have a positive impact on organizational ethics. To meet this objective, a content analysis was conducted on the written records of students formally charged with plagiarizing at a large West Coast university. Each case was classified according to the primary ethical reasoning that the student used to justify plagiarism. Results indicate that students predominately invoke deontology, situational ethics, and Machiavellianism. Based on these findings, specific recommendations are offered to curb plagiarism. (shrink)

Neil E. Williams develops a systematic metaphysics centred on the idea of powers, as a rival to neo-Humeanism, the dominant systematic metaphysics in philosophy today. Williams takes powers to be inherently causal properties and uses them as the foundation of his explanations of causation, persistence, laws, and modality.

On his death in 2007, Richard Rorty was heralded by the New York Times as “one of the world’s most influential contemporary thinkers.” Controversial on the left and the right for his critiques of objectivity and political radicalism, Rorty experienced a renown denied to all but a handful of living philosophers. In this masterly biography, Neil Gross explores the path of Rorty’s thought over the decades in order to trace the intellectual and professional journey that led him to that (...) prominence. The child of a pair of leftist writers who worried that their precocious son “wasn’t rebellious enough,” Rorty enrolled at the University of Chicago at the age of fifteen. There he came under the tutelage of polymath Richard McKeon, whose catholic approach to philosophical systems would profoundly influence Rorty’s own thought. Doctoral work at Yale led to Rorty’s landing a job at Princeton, where his colleagues were primarily analytic philosophers. With a series of publications in the 1960s, Rorty quickly established himself as a strong thinker in that tradition—but by the late 1970s Rorty had eschewed the idea of objective truth altogether, urging philosophers to take a “relaxed attitude” toward the question of logical rigor. Drawing on the pragmatism of John Dewey, he argued that philosophers should instead open themselves up to multiple methods of thought and sources of knowledge—an approach that would culminate in the publication of Philosophy and the Mirror of Nature , one of the most seminal and controversial philosophical works of our time. In clear and compelling fashion, Gross sets that surprising shift in Rorty’s thought in the context of his life and social experiences, revealing the many disparate influences that contribute to the making of knowledge. As much a book about the growth of ideas as it is a biography of a philosopher, Richard Rorty will provide readers with a fresh understanding of both the man and the course of twentieth-century thought.

Since Bruno Latour's discussion of a Sakhalin island map used by La Pérouse as part of a global network of “immutable mobiles,” the commensurability of European and non-European knowledge has become an important issue for historians of science. But recent studies have challenged these dichotomous categories as reductive and inadequate for understanding the fluid nature of identities, their relational origins, and their historically constituted character. Itineraries of knowledge transfer, traced in the wake of objects and individuals, offer a powerful heuristic (...) alternative, bypassing artificial epistemological divides and avoiding the limited scale of national or monolingual frames. Approaches that place undue emphasis either on the omnipotence of the imperial center or the centrality of the colonial periphery see only half the picture. Instead, practices of knowledge collection, codification, elaboration, and dissemination—in European, indigenous, and mixed or hybrid contexts—can be better understood by following their moveable parts, with a keen sensitivity toward non-normative epistemologies and more profound temporal frameworks. -/- .

Epistemic akrasia can be rational. I consider a lonely pragmatist who believes that her imaginary friend doesn’t exist, and also believes on pragmatic grounds that she should believe in him. She rationally believes that her imaginary friend doesn’t exist, rationally follows various sources of evidence to the view that she should believe in him to end her loneliness, and rationally holds these attitudes simultaneously. Evidentialism suggests that her ambivalent epistemic state is rational, as considerations grounded in the value of truth (...) justify her beliefs. (shrink)

So‐called downshifters seek more meaningful lives by decreasing the amount of time they devote to work, leaving more time for the valuable goods of friendship, family and personal development. But though these are indeed meaning‐conferring activities, they do not have the right structure to count as superlatively meaningful. Only in work – of a certain kind – can superlative meaning be found. It is by active engagements in projects, which are activities of the right structure, dedicated to the achievement of (...) goods beyond ourselves, that we make our lives superlatively meaningful.

This paper is a brief reponse to some of Douglas Portmore's criticisms of our version of the agent-relative/agent-neutral distinction.

What makes an argument in a law case good or bad? This book examines this and other questions central to the study of jurisprudence. Care has been taken to make the legal elements of the book readily accessible to non-lawyers, and the philosophical elements to non-philosophers.

In light of the growing need to pay attention to general public opinions and sentiments toward AI, this paper examines the levels of understandings amongst the Australian public toward the increased societal use of AI technologies. Drawing on a nationally representative survey of 2019 adults across Australia, the paper examines how aware people consider themselves to be of recent developments in AI; variations in popular conceptions of what AI is; and the extent to which levels of support for AI are (...) liable to alter with additional exposure to information about AI. While a majority of respondents consider themselves to have little knowledge and familiarity with the topic of AI, the survey nevertheless finds considerable range of relatively ‘plausible’ basic understandings of what AI is. Significantly, repeated questioning highlights a willingness among many people to reassess their opinions once having received further information about AI, and being asked to think through issues relating to AI and society. These patterns remain relatively consistent, regardless of respondents’ political orientation, income, social class and other demographic characteristics. As such, the paper concludes by considering how these findings provide support for the development of public education efforts to further enhance what might be termed ‘public understanding of AI’.

This article draws attention to a pattern of development within science and other intellectual research communities that has received virtually no mention. We propose that subsequent dominance of a research community by a figure responsible for significant innovation often delays progress in the field. During the period in which the revolutionary continues to influence research in a community, far too frequently the effect is to freeze progress within the limited directions which the revolutionary sanctions.

In this paper, we make the case that a person who is considering or has already made a decision that appears seriously harmful to that person should in some cases be judged incapable of making that...

Philosophers from Hart to Lewis, Johnston and Bennett have expressed various degrees of reservation concerning the doctrine of double effect. A common concern is that, with regard to many activities that double effect is traditionally thought to prohibit, what might at first look to be a directly intended bad effect is really, on closer examination, a directly intended neutral effect that is closely connected to a foreseen bad effect. This essay examines the extent to which the commonsense concept of intention (...) supports a reasonably consistent and coherent application of double effect. Two important conclusions are these: (1) a number of traditionally proscribed activities involve a kind of “targeting” of innocents that can be taken to exhibit a direct intention to harm them; (2) a direct intention to harm need not involve a desire to harm in any ordinary sense of the latter expression.
