Research suggests that perceptual experience of our movements adapts together with movement control when we are the agents of our actions. Is this agency critical for perceptual and motor adaptation? We had participants view cursor feedback during elbow extension–flexion movements when they actively moved their arm, or had their arm passively moved. We probed adaptation of movement perception by having participants report the reversal point of their unseen movement. We probed adaptation of movement control by having them aim to a (...) target. Perception and control of active movement were influenced by both types of exposure, although adaptation was stronger following active exposure. Furthermore, both types of exposure led to a change in the perception of passive movements. Our findings support the notion that perception and control adapt together, and they suggest that some adaptation is due to recalibrated proprioception that arises independently of active engagement with the environment.

How is a person's freedom related to his or her preferences? Liberal theorists of negative freedom have generally taken the view that the desire of a person to do or not do something is irrelevant to the question of whether he is free to do it. Supporters of the “pure negative” conception of freedom have advocated this view in its starkest form: they maintain that a person is unfree to Φ if and only if he is prevented from Φ-ing by (...) the conduct or dispositions of some other person. This definition of freedom is value-neutral in the sense that no reference is made to preferences over options or indeed to any other indicators of the values of options, either in the characterization of “Φ-ing” itself or in the characterization of the way in which Φ-ing can be constrained.

Hume’s account of the scope of justice, many think, is implausibly narrow, apply- ing almost exclusively to respect for property rights. Such a view would indeed be highly objectionable because it would leave out of the scope of justice altogether requirements to keep our promises, obey the law, and refrain from threats and violence (among many others). I argue that Hume’s theory of justice, properly understood, avoids this objection. And seeing how is instructive because once we understand his account correctly, (...) we can appreciate its resources for offering attractive explanations of why a number of diverse phenomena fall within the scope of justice. Overcoming this challenge is a major step- ping stone on the way to seeing Hume’s theory of justice as a genuine competitor with the other dominant theories of justice in the philosophical literature.

In his newly reissued and revised book, the philosopher Ian Dearden at- tempts a critical inquiry into a philosophical position he calls “nonsensi- calism,” which he takes to correspond to the view “that it is possible to be mistaken in thinking one means anything by what one says”.1 He holds that an unexamined assumption to this effect is implicit in a large swathe of philosophical work dating from a period stretching throughout most of the 20th century, thanks to the widespread (...) tendency of philosophers to accuse each other of talk- ing nonsense. This is, according to the author of the book, most visible in the earlier and later philosophical writings of Wittgenstein, in logical pos- itivism, and in representatives of the Oxford-based “ordinary language” philosophy movement, as well as in the writings of many of those subse- quently writing under the influence of these. Dearden coins a special term to refer to the sort of error that philosophers are accusing each other of having committed: he calls such cases of error “illusions of meaning.”. (shrink)

Many of the methods commonly used to research mathematical practice, such as analyses of historical episodes or individual cases, are particularly well-suited to generating causal hypotheses, but less well-suited to testing causal hypotheses. In this paper we reflect on the contribution that the so-called hypothetico-deductive method, with a particular focus on experimental studies, can make to our understanding of mathematical practice. By way of illustration, we report an experiment that investigated how mathematicians attribute aesthetic properties to mathematical proofs. We demonstrate (...) that perceptions of the aesthetic properties of mathematical proofs are, in some cases at least, subject to social influence. Specifically, we show that mathematicians’ aesthetic judgements tend to conform to the judgements made by others. Pedagogical implications are discussed. (shrink)

This article calls for an end to the use of the term ‘invasive species’, both in the scientific and public discourse on wildlife conservation. There are two broad reasons for this: the first problem with the invasive species narrative is that this demonisation of ‘invasives’ is morally wrong, particularly because it usually results in the unjust killing of the animals in question. Following on from this, the second problem is that the narrative is also incoherent, both from scientific and philosophical (...) perspectives. At the heart of both of these issues is the problem that the invasive species narrative oversimplifies what are in fact very complex biological processes. As a result, the policies carried out with the stated aim of ‘controlling’ these animals are often unethical. In light of the current global species decline, this article asserts that the way we think and talk about these animals should be changed and the term ‘invasive species’ should be discontinued, in the hope that this leads to changes in practice.

In this article, we report a study in which 109 research-active mathematicians were asked to judge the validity of a purported proof in undergraduate calculus. Significant results from our study were as follows: (a) there was substantial disagreement among mathematicians regarding whether the argument was a valid proof, (b) applied mathematicians were more likely than pure mathematicians to judge the argument valid, (c) participants who judged the argument invalid were more confident in their judgments than those who judged it valid, (...) and (d) participants who judged the argument valid usually did not change their judgment when presented with a reason raised by other mathematicians for why the proof should be judged invalid. These findings suggest that, contrary to some claims in the literature, there is not a single standard of validity among contemporary mathematicians. (shrink)

Aquinas is often presented as following Aristotle's "Nicomachean Ethics" when treating moral virtue. Less often do philosophers consider that Aquinas's conception of the highest good and its relation to the functional character of human activity led him to break with Aristotle by replicating each of the acquired moral virtues on an infused level. The author suggests that we can discern reasons for this move by examining Aquinas's commentary on the "Sententiae" of Peter the Lombard and the "Summa theologiae" within their (...) historical context. The author's thesis is that Dominican pastoral and intellectual concerns led Aquinas to argue that moral virtue must necessarily be ordered toward the highest good. Understanding this purpose helps to explain his presentation of moral virtue and its implications for standard philosophical interpretations of his work. (shrink)

Mathematicians often conduct aesthetic judgements to evaluate mathematical objects such as equations or proofs. But is there a consensus about which mathematical objects are beautiful? We used a comparative judgement technique to measure aesthetic intuitions among British mathematicians, Chinese mathematicians, and British mathematics undergraduates, with the aim of assessing whether judgements of mathematical beauty are influenced by cultural differences or levels of expertise. We found aesthetic agreement both within and across these demographic groups. We conclude that judgements of mathematical beauty (...) are not strongly influenced by cultural difference, levels of expertise, and types of mathematical objects. Our findings contrast with recent studies that found mathematicians often disagree with each other about mathematical beauty. (shrink)

The first volume of the Mediaeval Commentaries on the Sentences of Peter Lombard (=MCS1) edited by G. R. Evans in 2002 provided the first comprehensive study of those works that house much Latin medieval philosophy from the middle of the twelfth century to Martin Luther in the sixteenth century. Philipp Rosemann rounded out this project in 2007 with The Story of a Great Medieval Book: Peter Lombard's Sentences (Peterborough, ON: Broadview), which serves as an introduction to the second volume he (...) has now edited of the MCS (=MCS2). These volumes provide much of the context for Latin philosophical work in the later Middle Ages, which is arguably the most understudied period of Western thought. Steven Livesey gives .. (shrink)

The Islamic philosophical tradition was the privileged site for the study and continuation of the Classical philosophical tradition in the Middle Ages. An initial chapter on the history of Islamic philosophy sets the stage for sixteen articles on issues across the Islamic, Jewish and Christian traditions. The goal is to see the Islamic tradition in its own richness and complexity as the context of much Jewish intellectual work. Taken together, these two traditions provide the wider context to which Latin Christian (...) intellectuals would turn. The articles are grouped under six topics relevant both to the period and to current philosophical interest: the Islamic philosophical context, the nature of philosophy in the Middle Ages, Neoplatonism and the activity of the soul, creation, virtue, and the Latin reception. Since the nineteenth century Islamic and Jewish philosophy have been neglected in the standard histories of medieval philosophy. The time is right to begin to write a more balanced history of medieval philosophy. In order to begin to write this history, this book focuses on the Islamic, Jewish, and Christian use of - and reaction to - Classical philosophy during the Middle Ages. (shrink)

Many influential stances within the social sciences regard nature in one of two ways: either as none of their concern (which is with the social and cultural aspects of human existence), or as wholly a social and cultural fabrication. But there is also another strand of social scientific thinking that seeks to understand the interplay between social and cultural factors on one side and natural factors on the other. These volumes contain the main contributions that have been made within each (...) of these streams of thought. The selections illustrate to the reader the complexity of the various positions within these streams, and the strengths and limitations of each perspective. A new introduction places these articles in their historical and intellectual context and the volumes are completed with an extensive index and chronological table of contents. (shrink)

This is the first biography of the last and greatest British idealist philosopher, R. G. Collingwood, a man who both thought and lived at full pitch. Best known today for his philosophies of history and art, Collingwood was also a historian, archaeologist, sailor, artist, and musician. A figure of enormous energy and ambition, he took as his subject nothing less than the whole of human endeavor, and he lived in the same way, seeking to experience the complete range of human (...) passion. In this vivid and swiftly paced narrative, Fred Inglis tells the dramatic story of a remarkable life, from Collingwood's happy Lakeland childhood to his successes at Oxford, his archaeological digs as a renowned authority on Roman Britain, his solo sailing adventures in the English Channel, his long struggle with illness, and his sometimes turbulent romantic life. In a manner unheard of today, Collingwood attempted to gather all aspects of human thought into a single theory of practical experience, and he wrote sweeping accounts of history, art, science, politics, metaphysics, and archaeology, as well as a highly regarded autobiography. Above all, he dedicated his life to arguing that history--not science--is the only source of moral and political wisdom and self-knowledge. Linking the intellectual and personal sides of Collingwood's life, and providing a rich history of his milieu, History Man also assesses Collingwood's influence on generations of scholars after his death and the renewed recognition of his importance and interest today.

In exploring corporate perceptions of the business case for supplier diversity, this paper reports on a cross-national study of large purchasing organisations that had introduced, or were in the process of introducing, purchasing initiatives aimed at ethnic minority businesses. The research investigates how LPOs portray the benefits of this form of socially responsible purchasing and suggests a business case construct based on four component elements. It also highlights a number of contextual factors that appear to have shaped business case rationales. (...) The paper concludes with a discussion of issues of cost and contingent influences affecting SD programmes and points to possible areas for future research. (shrink)

‘Globalization’ has become in recent years one of the central themes of social scientific debates. Social theories of globalization may be regarded as specific academic and analytic manifestations of wider forms of ‘global consciousness’ to be found in the social world today. These are ways of thinking and perceiving which emphasize that the whole world should be seen as ‘one place’, its various geographically disparate parts all being interconnected in various complex ways. In this article we set out how both (...) a general ‘ecumenical sensibility’ involving such ways of thinking, and its specifically academic variant, an ‘ecumenical analytic’, are simultaneously responses to ‘globalizing conditions’ and also products of the latter. We demonstrate how social theories of globalization, locatable in the overall set we call the ‘ecumenical analytic’, are reflexive thought-products, in that they both seek to investigate, and are made possible by, ‘globalizing conditions’. Rejecting the view that both an ecumenical sensibility and an ecumenical analytic are solely products of modernity, we show how such modes of consciousness and analysis were present in the period of Greek history between the death of Alexander the Great and the rise of the Roman Empire. We show how at that period a socio-political situation akin in certain ways to modern ‘globalizing conditions’ generated both an ecumenical sensibility and an ecumenical analytic, the latter most forcefully represented by a revolutionary new genre in historiography called Universal History. By examining the ideas of its most famous practitioner, the historian Polybius, we demonstrate that Universal History both provided a framework for understanding what we today would call ‘globalization’, and exhibited a remarkable degree of reflexive awareness about its own conditions of possibility. We seek to show that an attentiveness to ‘global’ processes and a reflexive understanding of what makes that form of thinking possible in the first place, are not solely confined to modernity but were identifiable features of intellectual production in the Hellenistic period of ancient Greece. In this way we argue that scholars today should not imagine that the contemporary ‘global turn’ in social thought is either unique or wholly historically unprecedented. (shrink)

A common description of a mathematical proof is as a logically structured sequence of assertions, beginning from accepted premises and proceeding by standard inference rules to a conclusion. Does this description match the language of proofs as mathematicians write them in their research articles? In this chapter, we use methods from corpus linguistics to look at the prevalence of imperatives and instructions in mathematical preprints from the arXiv repository. We find thirteen verbs that are used most often to form imperatives (...) in proofs, and that these show up significantly more often within proofs than in the surrounding mathematical writing. We also show that there are many more verbs used to form a diverse selection of instructions in proofs. These findings are at odds with the view of proofs as sequences of assertions. Instead, we argue in favour of the recipe model of proofs: that proofs are like recipes, giving instructions for mathematical actions to be carried out. (shrink)

We examined a large set of conditional inference data compiled from several previous studies and asked three questions: How is normative performance related to intelligence? Does negative conclusion bias stem from Type 1 or Type 2 processing? Does implicit negation bias stem from Type 1 or Type 2 processing? Our analysis demonstrated that rejecting denial of the antecedent and affirmation of the consequent inferences was positively correlated with intelligence, while endorsing modus tollens inferences was not; that the occurrence of negative (...) conclusion bias was related to the extent of Type 2 processing; and that the occurrence of implicit negation bias was not related to the extent of Type 2 processing. We conclude that negative conclusion bias is, at least in part, a product of Type 2 processing, while implicit negation bias is not. (shrink)

Historically people with learning difficulties1 have been either included in research without their consent or excluded from research that affects their treatment and care. Over the last 20 years, however, it has been recognised that to exclude the voice of people with learning difficulties (and other so called vulnerable groups) in research that reflects their lived experiences challenges our notion of ethical practice. Cognitive ability has traditionally been one of the key factors in determining ability to consent. This paper identifies, (...) through work with a group of men with learning difficulties, the impact of different ways of presenting information to prospective participants on their ability to understand key issues in relation to participation in research and hence their ability to give informed consent2.

The Scottish Mental Health Arts and Film Festival has seen hundreds of arts, public and community groups coproduce over 300 events to over 25,000 audience members. Integral to this arts-based approach, in contrast to social marketing or public education models, is the notion that mental health is an essentially contested concept whereby meanings are negotiated and debate encouraged. With emerging evidence that the festival is an ef ective way of engaging people intellectually and emotionally, we explore ethical issues, challenges and (...) paradoxes that have emerged as the festival has developed. Consideration is given to issues of power, purpose, opportunity costs, reach, impact, programming risks, and participation from those with experience of mental ill-health. Throughout, we explore practical implications for funding, managing, programming, marketing and evaluation of this and similar endeavours. (shrink)

Many authors have commented on the relative frequency of the present tense—and the relative infrequency of the past tense—in mathematical writing. However, none (to our knowledge) have provided an estimate for the size of this effect or explored how universal it is. In this short note we report an analysis of corpora of mathematical and day-to-day English. We conclude that the present-to-past ratio of tenses is at least 3:1 in mathematical English, compared to approximately 5:7 in day-to-day English. Further, we (...) show that this tendency to favour the present tense is almost universally present in written mathematics. (shrink)

The purpose of this paper is to offer a sympathetic reconstruction of the political thought of Paul Feyerabend. Using a critical discussion of the idea of the ‘free society’ it is suggested that his political thought is best understood in terms of three thematic concerns – liberation, hegemony, and the authority of science – and that the political significance of those claims become clear when they are considered in the context of his educational views. It emerges that Feyerabend is best (...) understood as calling for the grounding of cognitive and cultural authorities – like the sciences – in informed deliberation, rather than the uncritical embrace of prevailing convictions. It therefore emerges that a free society is best understood as one of epistemically responsible citizenship rather than epistemically anarchistic relativism of the ‘anything goes’ – a striking anticipation of current debates about philosophy of science in society.

The neonatologist was describing the dire situation, the complexity of the fetus's anomalies, and the options—comfort care, some resuscitation—and finished by saying, “We would not recommend ECMO …” “We would not recommend” is a curious phrase. There is something ambiguous, very nebulous about it, something passive, noncommittal, maybe even deflective. As a bioethics researcher, I wondered how this phrase is interpreted, how it influences parents' moral deliberation over their options.

Stories in which a hero defeats a semi-human ogre occur much more frequently in unrelated cultures than chance alone can account for. This claim is supported by a discussion of folk-tales from 20 cultures and an examination of the folk-tales from a random sample of 44 cultures. The tendency to tell these stories must, therefore, have its source in the innate human nature discussed by evolutionary psychologists. This essay argues that these stories reinforce innate positive biases in the perception of (...) self and ingroup and negative biases in the perception of outgroups. (shrink)

Social theory is a crucial resource for the social sciences. It provides rich insights into how human beings think and act and how contemporary social life is constructed. But often the key ideas of social theorists are expressed in highly technical and difficult language that can hide more than it reveals. The new edition of this popular book continues to cut to the core of what social theory is about. Covering key themes from the classical thinkers onwards, including Marxism, post-structuralism, (...) phenomenology, feminism and more, the second edition features a new chapter on Actor-Network Theory and enhanced discussion of postcolonial theory. Wide ranging in scope and coverage, the book is concise in presentation and free from jargon. Showing why social theory matters, and why it is of far-reaching social and political importance, the book is ideal for readers seeking a clear, crisp mapping of a complex but very rewarding area.

Philosophical issues of hospitality are bound up with broader issues of cosmopolitanism in thought and in practice. This paper considers the interplay of human faces, masks, forms of hospitality, and cosmopolitanizing and anti-cosmopolitanizing socio-political dynamics in the time of Covid-19. Despite confident assertions by some interested parties that it is now finished and past history, Covid-19 remains a major challenge across the globe, and so reflections on the interplay of masking, cosmopolitanism, and hospitality remain pertinent today and are not merely (...) a quaint feature of life during the early years of the pandemic. Voluntary acts of self-masking are argued to be more than just mundane forms of micro-level action and interaction among persons. Instead, freighted sometimes with political meaning, and certainly loaded with ethical force, the donning of a face mask can operate as a small but compelling quotidian act of cosmopolitan concern and hospitableness towards other people, including those perceived to be very unlike oneself.

It seems beyond doubt that a thinker can come to know a conclusion by deducing it from premisses that he knows already, but philosophers have found it puzzling how a thinker could acquire knowledge in this way. Assuming a broadly externalist conception of knowledge, I explain why judgements competently deduced from known premisses are themselves knowledgeable. Assuming an exclusionary conception of judgeable content, I further explain how such judgements can be informative. (According to the exclusionary conception, which I develop from (...) some remarks in Ramsey, a judgement's content is given by the hitherto live possibilities that it excludes or rules out.) I propose that the value of logic lies in its allowing us to combine different sources of knowledge, so that we can learn things that we could not learn from those sources individually. I conclude by arguing that while single-conclusion logics possess that value, multiple-conclusion logics do not. (shrink)

In recent times developments in the natural sciences and in the sphere of environmental politics have compelled social scientists, and also some natural scientists, to rethink the relations that hitherto have been held, in Western thought generally and within particular disciplines, to characterize ‘nature’ on the one side and ‘culture’ on the other. This article considers the history of this conceptual boundary and looks at new conceptualizations of nature/culture, stimulated by developments both in biotechnology and in the ongoing controversies about (...) environmental degradation. It argues that while some of the contributions to reconfiguring, or abolishing, the nature/ culture division have been productive and stimulating of new ways of conceiving the world, there has nonetheless been an unfortunate tendency for social scientists to bring to bear inherited analytic dispositions on biotechnological and environmental matters. Instead of using these issues as means of challenging social scientific disciplinary dogmas and of engaging in constructive rapprochement with natural scientists, social scientists have in their analyses of such matters often merely asserted the hegemony of ‘culture’ over ‘nature’, and thus in effect the superiority of social scientific over natural scientific conceptualizations of the world. Far from overcoming the nature/culture boundary, social scientists have too often merely asserted the primacy of the sorts of subject matters and analytic techniques they feel comfortable with, rather than subjecting their practices to fully reflexive self-scrutiny.
