Philip Pettit offers a new insight into moral psychology. He shows that attachments such as love, and certain virtues such as honesty, require their characteristic behaviours not only as things actually are, but also in cases where things are different from how they actually are. He explores the implications of this idea for key moral issues.

Research on personality psychology is making important contributions to psychological science and applied psychology. This second edition of The Cambridge Handbook of Personality Psychology offers a one-stop resource for scientific personality psychology. It summarizes cutting-edge personality research in all its forms, including genetics, psychometrics, social-cognitive psychology, and real-world expressions, with informative and lively chapters that also highlight some areas of controversy. The team of renowned international authors, led by two esteemed editors, ensures a wide range of theoretical perspectives. Each research (...) area is discussed in terms of scientific foundations, main theories and findings, and future directions for research. The handbook also features advances in technology, such as molecular genetics and functional neuroimaging, as well as contemporary statistical approaches. An invaluable aid to understanding the central role played by personality in psychology, it will appeal to students, researchers, and practitioners in psychology, behavioral neuroscience, and the social sciences.

In social identity theory, the in-Christ identity is understood as primarily a socially directed process in which people categorise themselves relative to other groups. Intergroup behaviour would cause them to discriminate against the so-called ‘outgroup’, favouring the so-called ‘ingroup’. Although social identity complexity theory has moved beyond single ingroup-outgroup categorisation, it is a question if social identity theories can fully account for the in-Christ identity, especially within an African context. In African religious identity, identity is linked to both the community (...) and the ruling deities, which are perceived to be real entities that intervene in human affairs and identity, presupposing a supernaturalistic epistemology. Contribution: In this contribution, the naturalistic epistemological underpinnings of social identity theories are reconsidered in light of a supernatural aspect that is argued to be constitutive of the 1st century in-Christ identity as well as the African Christian identity. Amid current approaches to the in-Christ identity, which is mainly a Pauline concept, some of the main Pauline texts that have bearing on the in-Christ identity are revisited in light of current theories and epistemologies on identity.

This is the first complete English translation of Gottlob Frege's Grundgesetze der Arithmetik, with introduction and annotation. The importance of Frege's ideas within contemporary philosophy would be hard to exaggerate. He was, to all intents and purposes, the inventor of mathematical logic, and the influence exerted on modern philosophy of language and logic, and indeed on general epistemology, by the philosophical framework.

Philip Pettit has drawn together here a series of interconnected essays on three subjects to which he has made notable contributions. The first part of the book discusses the rule-following character of thought. The second considers how choice can be responsive to different sorts of factors, while still being under the control of thought and the reasons that thought marshals. The third examines the implications of this view of choice and rationality for the normative regulation of social behaviour. Rules, (...) Reasons, and Norms makes original and illuminating connections across a large swathe of territory, from metaphysics to philosophical psychology to the theory of rational regulation. (shrink)

A minimum voting age is defended as the most effective and least disrespectful means of ensuring all members of an electorate are sufficiently competent to vote. Whilst it may be reasonable to require competency from voters, a minimum voting age should be rejected because its view of competence is unreasonably controversial, it is incapable of defining a clear threshold of sufficiency and an alternative test is available which treats children more respectfully. This alternative is a procedural test for minimum electoral (...) competence. A procedural test for minimum electoral competence also succeeds in fulfilling adults’ duties to promote children’s rational and moral engagement with democracy. A minimum voting age should therefore be rejected, all things considered. A procedural test for minimum literacy and independent voting is the most justified means to ensure competency from voters and to promote the democratic agency of children. (shrink)

In his monograph On Numbers and Games, J. H. Conway introduced a real-closed field containing the reals and the ordinals as well as a great many less familiar numbers including $-\omega, \,\omega/2, \,1/\omega, \sqrt{\omega}$ and $\omega-\pi$ to name only a few. Indeed, this particular real-closed field, which Conway calls No, is so remarkably inclusive that, subject to the proviso that numbers—construed here as members of ordered fields—be individually definable in terms of sets of NBG, it may be said to contain (...) “All Numbers Great and Small.” In this respect, No bears much the same relation to ordered fields that the system ℝ of real numbers bears to Archimedean ordered fields. In Part I of the present paper, we suggest that whereas $\mathbb{R}$should merely be regarded as constituting an arithmetic continuum, No may be regarded as a sort of absolute arithmetic continuum, and in Part II we draw attention to the unifying framework No provides not only for the reals and the ordinals but also for an array of non-Archimedean ordered number systems that have arisen in connection with the theories of non-Archimedean ordered algebraic and geometric systems, the theory of the rate of growth of real functions and nonstandard analysis. In addition to its inclusive structure as an ordered field, the system No of surreal numbers has a rich algebraico-tree-theoretic structure—a simplicity hierarchical structure—that emerges from the recursive clauses in terms of which it is defined. In the development of No outlined in the present paper, in which the surreals emerge vis-à-vis a generalization of the von Neumann ordinal construction, the simplicity hierarchical features of No are brought to the fore and play central roles in the aforementioned unification of systems of numbers great and small and in some of the more revealing characterizations of No as an absolute continuum.

A theory of the first-person plural occupies a unique place in philosophical investigations into intersubjectivity and social cognition. In order for the referent of the first-person plural—“the We”—to come into existence, it seems there must be a shared ground of communicative possibility, but this requires a non-circular explanation of how this ground could be shared in the absence of a pre-existing context of communicative conventions. Margaret Gilbert’s and John Searle’s theories of collective intentionality capture important aspects of the We, but (...) fail to fully account for this shared ground of communicative possibility. This paper argues that Merleau-Ponty’s concept of intercorporeity helps reconcile the positive aspects of these accounts while also explaining how the genesis of the social world is continuous with perceptual life in general. This enables an account of the first-person plural as dependent on reciprocal communicative interaction without the need to posit a primitive or primordial “we-mode” of consciousness. “Intercorporeity” designates a bodily openness to others that is not fundamentally different in kind from the general style of bodily comportment found in Merleau-Ponty’s rich analyses of perceptual life.

In late March of 2020, a new hashtag, #FilmYourHospital, made its first appearance on social media. The hashtag encouraged people to visit local hospitals to take pictures and videos of empty hospitals to help “prove” that the COVID-19 pandemic is an elaborate hoax. Using techniques from Social Network Analysis, this case study examines how this conspiracy theory propagated on Twitter and whether the hashtag virality was aided by the use of automation or coordination among Twitter users. We found that while (...) much of the content came from users with limited reach, the oxygen that fueled this conspiracy in its early days came from a handful of prominent conservative politicians and far right political activists on Twitter. These power users used this hashtag to build awareness about the campaign and to encourage their followers to break quarantine and film what is happening at their local hospitals. After the initial boost by a few prominent accounts, the campaign was mostly sustained by pro-Trump accounts, followed by a secondary wave of propagation outside the U.S. The rise of the #FilmYourHospital conspiracy from a single tweet demonstrates the ongoing challenge of addressing false, viral information during the COVID-19 pandemic. While the spread of misinformation can be potentially mitigated by fact-checking and directing people to credible sources of information from public health agencies, false and misleading claims that are driven by politics and supported by strong convictions and not science are much harder to root out.

Between the affirmative and the negative, the compositional and the oppositional, we need to rethink the difference between difference and contradiction. In this regard, the concept of ‘diplomacy’, as developed by Isabelle Stengers, is of particular significance. Whereas many adherents of an affirmative ontology of difference reduce contradiction to a caveat – ‘of course, antagonism is inevitable, but …’ – diplomacy makes contradiction its fundamental concern. This article explicates the significance of such a conception, via close readings of Stengers’ work (...) in relation to that of Gilles Deleuze, and Gottfried Wilhelm Leibniz. However, it also develops diplomacy in new directions, particularly relating the diplomatic ‘fold’ to the sovereign ‘cut’. The fold of coexistence, then, is achieved through diplomacy as a ‘labour of difference’, against ‘facile pluralism’, which takes worldly cohabitation as given. A diplomatic political ontology is neither bellicose nor pacific; rather, it dramatizes the possibility of peace from within a coercive historical reality. (shrink)

Approach–avoidance theories describe the major systems that motivate behaviours in reaction to classes of appetitive (rewarding) and aversive (punishing) stimuli. The literature points to two major “avoidance” systems, one related to pure avoidance and escape of aversive stimuli, and a second, to behavioural inhibition induced by the detection of goal conflict (in addition, there is evidence for nonaffective behavioural constraint). A third major system, responsible for approach behaviour, is reactive to appetitive stimuli, and has several subcomponents. A number of combined (...) effects of these systems are outlined. Finally, the hierarchical nature of behavioural control is delineated, including the role played by conscious awareness in behavioural inhibition. (shrink)

We examine the notions of negative, infinite and hotter than infinite temperatures and show how these unusual concepts gain legitimacy in quantum statistical mechanics. We ask if the existence of an infinite temperature implies the existence of an actual infinity and argue that it does not. Since one can sensibly talk about hotter than infinite temperatures, we ask if one could legitimately speak of other physical quantities, such as length and duration, in analogous terms. That is, could there be longer (...) than infinite lengths or temporal durations? We argue that the answer is surprisingly yes, and we outline the properties of a number system that could be employed to characterize such magnitudes. (shrink)

Abstractionism, which is a development of Frege's original Logicism, is a recent and much debated position in the philosophy of mathematics. This volume contains 16 original papers by leading scholars on the philosophical and mathematical aspects of Abstractionism. After an extensive editors' introduction to the topic of abstractionism, the volume is split into 4 sections. The contributions within these sections explore the semantics and meta-ontology of Abstractionism, abstractionist epistemology, the mathematics of Abstractionis, and finally, Frege's application constraint within an abstractionist (...) setting.

We develop and defend a distinction between two types of self-censorship: public and private. First, we suggest that public self-censorship refers to a range of individual reactions to a public censorship regime. Second, private self-censorship is the suppression by an agent of his or her own attitudes where a public censor is either absent or irrelevant. The distinction is derived from a descriptive approach to self-censorship that asks: who is the censor, who is the censee, and how do they interact? (...) We label situations in which censor and censee are different agents as public self-censorship, and situations in which they are the same agents as private self-censorship. We demonstrate the salience of this distinction by analysing the case of publication of Mohammed cartoons by the Danish newspaper Jyllands-Posten. Our analysis reveals the presence and interaction of a number of different instances of private and public self-censorship. While our article is primarily concerned with establishing this novel descriptive distinction between public and private self-censorship, our analysis has important evaluative implications. We explain for instance how Jyllands-Posten was laudable as a public self-censor but not so as a private self-censor. In general, our analysis reveals that the agents and processes involved in public and private self-censorship are substantively different, as are the agents to whom normative principles regarding censorship should be applied. In particular, principles of free speech do not apply to the case of private self-censorship, because while an instance of censorship, the absence of an external censor makes the censorship non-coercive.

Andrew Kania has attempted to argue for nihilistic fictionalism about musical works. This view combines an error theory about musical work discourse with the proposal that musical work discourse has a non-alethic value which warrants continued participation in it. In this paper, I argue that Kania fails to establish either component of nihilistic fictionalism. First, I elaborate and reject Kania’s attempt to establish fictionalism on the basis of a methodological proposal he calls ‘descriptivism’. I argue that the methodology is unpopular, (...) unappealing and that the interest in its implications is unclear. What is worse descriptivism does not support fictionalism. I then elaborate and reject Kania’s attempt to establish fictionalism as the best theory compatible with nominalism. I argue that, even by Kania’s standards, eliminativist nominalism, materialist nominalism and materialist fictionalism are preferable to nihilistic fictionalism. (shrink)

Since Euclid defined a point as “that which has no part” it has been widely assumed that points are necessarily unextended. It has also been assumed that this is equivalent to saying that points or, more properly speaking, degenerate segments, have length zero. We challenge these assumptions by providing models of Euclidean geometry where the points are extended despite the fact that the degenerate segments have null lengths, and observe that whereas the extended natures of the points are not recognizable (...) in the given models, they can be recognized and characterized by structures that are suitable expansions of the models.

This paper discusses the neo-logicist approach to the foundations of mathematics by highlighting an issue that arises from looking at the Bad Company objection from an epistemological perspective. For the most part, our issue is independent of the details of any resolution of the Bad Company objection and, as we will show, it concerns other foundational approaches in the philosophy of mathematics. In the first two sections, we give a brief overview of the "Scottish" neo-logicist school, present a generic form (...) of the Bad Company objection and introduce an epistemic issue connected to this general problem that will be the focus of the rest of the paper. In the third section, we present an alternative approach within philosophy of mathematics, a view that emerges from Hilbert's Grundlagen der Geometrie (1899, Leipzig: Teubner; Foundations of geometry (trans.: Townsend, E.). La Salle, Illinois: Open Court, 1959.). We will argue that Bad Company-style worries, and our concomitant epistemic issue, also affects this conception and other foundationalist approaches. In the following sections, we then offer various ways to address our epistemic concern, arguing, in the end, that none resolves the issue. The final section offers our own resolution which, however, runs against the foundationalist spirit of the Scottish neo-logicist program. (shrink)

For Martin, the right to free higher education may be claimed only by those ready and willing pursue autonomy supporting higher education. The unready and unwilling, among whom may be counted carers, disabled, and devout, are excluded. This is unjust. I argue that this injustice follows from a tension between three elements of Martin’s argument: (1) a universal right to autonomy supporting higher education; (2) qualifications on entitlements to access this right in order to preserve the value of higher educational (...) goods; (3) luck egalitarian motivations in Martin’s distributive ethics. I consider options for avoiding such injustices and their implications for Martin’s argument. (shrink)

How should we understand the duties between those who share in parenting a child? Those who engage in shared parenting have duties to each other derived from the child's interests, but they also have additional duties to each other as sharers in parenting. The intentional account of duties between parents appears unable to explain the stringency of duties of shared parenting, as it seems to permit a parent to relinquish unilaterally their duties of shared parenting. Drawing on the work of (...) Bratman, Alonso, and Scanlon, I develop a shared intention account of duties of shared parenting. Duties of shared parenting are constituted by the distinctive combination of the value of reliance in shared intentions, the importance of assurance in agreements, the significance of autonomy is deciding one's goals, and the entitlement to choose with whom one shares the intimacy of parenting. On this view, duties of shared parenting are shown to be stringent, but not duties of strict performance. Thus, I argue that the intentional account of parental duties is able to explain the stringency of duties of shared parenting. (shrink)

Philosopher Rene Descartes visualized a world unified by mathematics, in which all intellectual issues could be resolved rationally by local computation. This series of provocative essays takes a modern look at the seventeenth-century thinker’s dream, examining the physical and intellectual influences of mathematics on society, particularly in light of technological advances. They survey the conditions that elicit the application of mathematic principles; the effectiveness of these applications; and how applied mathematics constrain lives and transform perceptions of reality. Highly suitable for (...) browsing, the essays require different levels of mathematical knowledge that range from popular to professional. 1987 ed. (shrink)

In this paper I will argue that Boghossian's explanation of how we can acquire a priori knowledge of logical principles through implicit definitions commits a transmission of warrant-failure. To this end, I will briefly outline Boghossian's account, followed by an explanation of what a transmission of warrant-failure consists in. I will also show that this charge is independent of the worry of rule-circularity which has been raised concerning the justification of logical principles and of which Boghossian is fully aware. My (...) argument comes in two steps: firstly, I will argue for the insufficiency of Boghossian's template which is meant to explain how a subject can acquire a warrant for logical principles. I will show however that this insufficiency of his template can be remedied by adopting what I call the Disquotational Step. Secondly, I will argue that incorporating this further step makes his template subject to a transmission of warrant-failure, assuming that certain rather basic and individually motivated principles hold. Thus, Boghossian's account faces a dilemma: either he adopts the Disquotational Step and subjects his account to the charge of a transmission of warrant-failure, or he drops this additional step leaving the account confronted with explaining the gap that has previously been highlighted. I will then suggest various rejoinders that Boghossian might adopt but none of which - I will argue - can resolve the dilemma. Lastly, I will raise and briefly discuss the question whether this worry generalizes to other accounts, such as Hale and Wright's that aim to explain our knowledge of logic and/or mathematics in virtue of implicit definitions.

The s, p, d and f blocks of the elements, as delimited by Charles Janet in 1928, can be represented as parallel slices of a regular tetrahedron. They also fit neatly on to the surface of a sphere. The reasons for this are discussed and the possible objections examined. An attempt is made to see whether there are philosophical implications of this unexpected geometrical regularity. A new tetrahedral design in transparent plastic is presented.

This paper argues that education should become more evidence-based. The distinction is made between using existing research and establishing high-quality educational research. The need for highquality systematic reviews and appraisals of educational research is clear. Evidence-based education is not a panacea, but is a set of principles and practices for enhancing educational policy and practice.

If someone abstains from meat-eating for reasons of taste or personal economics, no moral or philosophical question arises. But when a vegetarian attempts to persuade others that they, too, should adopt his diet, then what he says requires philosophical attention. While a vegetarian might argue in any number of ways, this essay will be concerned only with the argument for a vegetarian diet resting on a moral objection to the rearing and killing of animals for the human table. The vegetarian, (...) in this laense, does not merely require us to change or justify our eating habits, but to reconsider our attitudes and behaviour towards members of other species across a wide range of practices.

Hannah Arendt is widely regarded as a political theorist who sought to rescue politics from ‘society’, and political theory from the social sciences. This conventional view has had the effect of distracting attention from many of Arendt’s most important insights concerning the constitution of ‘society’ and the significance of the social sciences. In this article, I argue that Hannah Arendt’s distinctions between labor, work and action, as these are discussed in The Human Condition and elsewhere, are best understood as a (...) set of claims about the fundamental structures of human societies. Understanding Arendt in this way introduces interesting parallels between Arendt’s work and both classical and contemporary sociology. From this I draw a number of conclusions concerning Arendt’s conception of ‘society’, and extend these insights into two contemporary debates within contemporary theoretical sociology: the need for a differentiated ontology of the social world, and the changing role that novel forms of knowledge play in contemporary society as major sources of social change and order.

Roger Crisp has inspired two important criticisms of Scanlon's buck-passing account of value. I defend buck-passing from the wrong kind of reasons criticism, and the reasons and the good objection. I support Rabinowicz and Rønnow-Rasmussen's dual role of reasons in refuting the wrong kind of reasons criticism, even where its authors claim it fails. Crisp's reasons and the good objection contends that the property of goodness is buck-passing in virtue of its formality. I argue that Crisp conflates general and formal (...) properties, and that Scanlon is ambiguous about whether the formal property of a reason can stop the buck. Drawing from Wallace, I respond to Crisp's reasons and the good objection by developing an augmented buck-passing account of reasons and value, where the buck is passed consistently from the formal properties of both to the substantive properties of considerations and evaluative attitudes. I end by describing two unresolved problems for buck-passers. (shrink)

The Tidal Model represents a significant alternative to mainstream mental health theories, emphasizing how those suffering from mental health problems can benefit from taking a more active role in their own treatment. Based on extensive research, The Tidal Model charts the development of this approach, outlining the theoretical basis of the model to illustrate the benefits of a holistic model of care which promotes self-management and recovery. Clinical examples are also employed to show how, by exploring rather than ignoring a (...) client's narrative, practitioners can encourage the individual's greater involvement in the decisions affecting their assessment and treatment. The Tidal Model 's comprehensive coverage of the theory and practice of this model will be of great use to a range of mental health professionals and those in training in the fields of mental health nursing, social work, psychotherapy, clinical psychology and occupational therapy.

There is broad agreement that child labor is wrong and should be eliminated. This chapter examines the three main moral objections to child labor and considers their limitations: harm-based objections, objections from failing to benefit children, and objections from exploitation. Harm-based objections struggle with baselines for comparison and difficulties with Non-Identity problems. Even if child labor is not harmful, it may be wrong because it prevents children from enjoying other benefits, such as schooling. However, is schooling necessarily more beneficial for (...) children than work? Some kinds of child labor may not be harmful, and may benefit children, but they may still be wrong because they are exploitative. I consider some ways to address exploitative child labor, inspired by campaigns led by child workers. The chapter ends with a surprising conclusion that challenges the broad consensus with which we began: we may have duties to promote child labor. (shrink)
