There has been increased attention on how scientific communities should respond to spurious dissent. One proposed method is to hide such dissent by preventing its publication. To investigate this, I computationally model the epistemic effects of hiding dissenting evidence on scientific communities. I find that it is typically epistemically harmful to hide dissent, even when there exists an agent purposefully producing biased dissent. However, hiding dissent also allows for quicker correct epistemic consensus among scientists. Quicker consensus may be important when (...) policy decisions must be made quickly, such as during a pandemic, suggesting times when hiding dissent may be useful. (shrink)

If the end of metaphysics is not upon us, then phenomenology must be at an end instead. Or so we are told, at least, by the “new realists,” or at least by some of the thinkers I’ll refer to using this term. And why shouldn’t we agree with them? If there’s anything at all to be said for the line of thinking that they advance, then today, we are at long last licensed to speak about beings once again; but apparently, (...) phenomenology deals only with consciousness, which we must admit—assuming we have a realist bone in our bodies—does not determine beings themselves at all. To persist with the phenomenological method, rather, would be to block all progress in philosophy—or so, again, some of these “new realists” will... (shrink)

Ostensibly, Heidegger’s notion of Befindlichkeit isn’t one of the really enigmatic concepts in his oeuvre—for everyone knows that on Heidegger’s account, this phenomenon, which bears at least some connection to what we normally call emotion, provides a basic disclosure of “the Dasein’s” worldly engagement. Nonetheless, there are enigmas here, given that Heidegger connects the phenomenon of Befindlichkeit with the disclosure of the Dasein’s past, as well as to its “thrownness” and its cultural heritage, none of which seems transparently true of (...) emotions. Some clarification is called for, then—and as I attempt to demonstrate in this article, this is possible only by interpreting the notion of Befindlichkeit in the context of an element of Husserl’s account of time- and self-consciousness that Heidegger incorporated as a central feature of his own, amended account of temporality—namely, Husserl’s notion of the protentional fulfillment that, on his reckoning, lies at the heart of this consciousness. Interpreting Heidegger’s account of Befindlichkeit in this fashion, I also show how, so interpreted, it can help us to make headway in both contemporary emotion studies and the currently developing critical theories of affect.

On Dan Zahavi’s Husserlian account of the subject, the self-temporalization of subjectivity presupposes what he calls an “immediate impressional self-manifestation.” It follows from this view that self-awareness is an inherent power of the one who will be subject, rather than a product of sociality introduced into life from without. In this paper, I argue against Zahavi’s position by going over the development of Husserl’s account of time-consciousness, examining the positions Husserl takes and the reasons that he comes to these positions. (...) Once we reach Husserl’s ultimate account, it becomes evident that Zahavi’s position is untenable. (shrink)

As the title of my article has probably made clear already, this will be an essay on the work of Emmanuel Levinas and John Rawls—and while I might not be the first person ever to compose a paper about Levinas and Rawls together, I'll probably be the second or third if not.

However, in clinical practice, MMF dose reduction, interruption, or discontinuation due to (...) hematological and gastrointestinal side-effects occurred in up to 50% of the patients. Large retrospective analyses have demonstrated that patients requiring MMF dose manipulation due to adverse events experienced a higher rate of rejection and graft loss. Enteric-coated mycophenolate sodium was developed with the goal of improving upper GI side-effects. Here, we review the efficacy and safety of EC-MPS in de novo kidney transplant recipient, and in stable renal transplant patients who were converted from MMF. The changes in GI-related adverse events using patient-reported outcome instruments are also reviewed.Keywords: enteric-coated mycophenolate sodium, mycophenolate mofetil, kidney transplant, efficacy, gastrointestinal tolerability.

Blame is usually discussed in the context of the free will problem, but recently moral philosophers have begun to examine it on its own terms. If, as many suppose, free will is to be understood as the control relevant to moral responsibility, and moral responsibility is to be understood in terms of whether blame is appropriate, then an independent inquiry into the nature and ethics of blame will be essential to solving (and, perhaps, even fully understanding) the free will problem. (...) In this article we first survey and categorize recent accounts of the nature of blame – is it action, belief, emotion, desire, or something else? – and then we look at several proposed requirements on appropriate blame that look beyond the transgressor himself, considerations that will form part of a full account of the ethics of blame.

Experiences of Depression is a philosophical exploration of what it is like to be depressed. In this important new book, Matthew Ratcliffe develops a detailed account of depression experiences by drawing on work in phenomenology, philosophy of mind and psychology, and several other disciplines.

This chapter describes the attributionist approach to moral responsibility. Works by Pamela Hieronymi, T.M. Scanlon, Angela Smith, and Matthew Talbert are taken to representative of this approach. On the interpretation given here, attributionism is committed to the following: assessments of moral responsibility are, and ought to be, centrally concerned with the morally significant features of an agent’s orientation toward others that are attributable to her, and an agent is eligible for moral praise or blame solely on the basis of (...) these attributions. Attributionism is presented as rejecting the claim that agents are morally responsible only for what is under their voluntary control, as well as the claim that agents are responsible for wrongdoing only if they could have responded to the moral considerations that spoke against your behavior. These supposed conditions on moral responsibility are rejected for the same reason: agents may reveal features of their selves, in a way that is sufficient for moral responsibility, even in cases in which these conditions are not met.

In Real Hallucinations, Matthew Ratcliffe offers a philosophical examination of the structure of human experience, its vulnerability to disruption, and how it is shaped by relations with other people. He focuses on the seemingly simple question of how we manage to distinguish among our experiences of perceiving, remembering, imagining, and thinking. To answer this question, he first develops a detailed analysis of auditory verbal hallucinations (usually defined as hearing a voice in the absence of a speaker) and thought insertion (...) (somehow experiencing one's own thoughts as someone else's). He shows how thought insertion and many of those experiences labeled as "hallucinations" consist of disturbances in a person's senseof being in one type of intentional state rather than another. Ratcliffe goes on to argue that such experiences occur against a backdrop of less pronounced but wider-ranging alterations in the structure of intentionality. In so doing, he considers forms of experience associated with trauma, schizophrenia, and profound grief. The overall position arrived at is that experience has an essentially temporal structure, involving patterns of anticipation and fulfillment that are specific to types of intentional states and serve to distinguish them phenomenologically. Disturbances of this structure can lead to various kinds of anomalous experience. Importantly, anticipation-fulfillment patterns are sustained, regulated, and disrupted by interpersonal experience and interaction. It follows that the integrity of human experience, including the most basic sense of self, is inseparable from how we relate to other people and to the social world as a whole. (shrink)

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

Spinoza was one of the most influential figures of the Enlightenment, but his often obscure metaphysics makes it difficult to understand the ultimate message of his philosophy. Although he regarded freedom as the fundamental goal of his ethics and politics, his theory of freedom has not received sustained, comprehensive treatment. Spinoza holds that we attain freedom by governing ourselves according to practical principles, which express many of our deepest moral commitments. Matthew J. Kisner focuses on this theory and presents (...) an alternative picture of the ethical project driving Spinoza's philosophical system. His study of the neglected practical philosophy provides an accessible and concrete picture of what it means to live as Spinoza's ethics envisioned. (shrink)

Drawing on examples from the history of warfare from the crusades to the present day, "The ethics of war" explores the limits and possibilities of the moral regulation of war. While resisting the commonly held view that 'war is hell', A.J. Coates focuses on the tensions which exist between war and morality. The argument is conducted from a just war standpoint, though the moral ambiguity and mixed record of that tradition is acknowledge and the dangers which an exaggerated view (...) of the justice or moral worth of war poses are underlined. In the first part, the broad image of the just war is compared with the competing images of realism, militarism and pacifism. In the second part, the moral issues associated both with the decision to go to war and with the manner in which war is conducted are explored. Was the allied decision to go to war in the Gulf premature? were economic sanctions a more effective and morally preferable option? was Britain justified in going to war over the Falklands? did the allied bombing of Germany in the Second World War constitute a war crime? should the IRA's claim to belligerent status be recognised? these questions and more are raised in this important book.

Why do war crimes occur? Are perpetrators of war crimes always blameworthy? In an original and challenging thesis, this book argues that war crimes are often explained by perpetrators' beliefs, goals, and values, and in these cases perpetrators may be blameworthy even if they sincerely believed that they were doing the right thing.

Most people would agree that a small child, or a cognitively impaired adult, is less responsible for their actions, good or bad, than an unimpaired adult. But how do we explain that difference, and how far can anyone be praised or blamed for what they have done? In this fascinating introduction, Matthew Talbert explores some of the key questions shaping current debates about moral responsibility, including: What is free will, and is it required for moral responsibility? Are we responsible (...) for the unforeseen consequences of our actions? Is it fair to blame people for doing what they believe is right? And are psychopaths open to blame? As Talbert argues, we are morally responsible for our actions when they are related to us in particular ways: when our actions express our true selves, for example, or when we exercise certain kinds of control over them. It is because we bear these relationships to our actions that we are open to praise and blame. _Moral Responsibility_ will be an important resource for students and researchers in ethics, moral psychology, and philosophy of agency and of great interest to all those wishing to understand an important aspect of our moral practices.

What do mathematicians mean when they use terms such as ‘deep’, ‘elegant’, and ‘beautiful’? By applying empirical methods developed by social psychologists, we demonstrate that mathematicians' appraisals of proofs vary on four dimensions: aesthetics, intricacy, utility, and precision. We pay particular attention to mathematical beauty and show that, contrary to the classical view, beauty and simplicity are almost entirely unrelated in mathematics.

We suggest a rigorous theory of how objective single-case transition probabilities fit into our world. The theory combines indeterminism and relativity in the “branching space–times” pattern, and relies on the existing theory of causae causantes (originating causes). Its fundamental suggestion is that (at least in simple cases) the probabilities of all transitions can be computed from the basic probabilities attributed individually to their originating causes. The theory explains when and how one can reasonably infer from the probabilities of one “chance (...) set-up” to the probabilities of another such set-up that is located far away. (shrink)

It is widely held that if an agent is not morally responsible for her action – i.e., if she is not deserving of blame – then we have a (decisive) reason to refrain from blaming her. But though this is true, the fact that someone is deserving of blame isn’t clearly sufficient for there to be most allthings- considered reason for blaming that person. Other considerations bear on this question as well. Coates offers an account of some of these (...) considerations – particularly those that can serve as deontic constraints on blame. He also offers a reply to those skeptical of the “ethics of blame” on the grounds that such theorizing invariably appeals to the “wrong kind of reasons.”. (shrink)

In an advertisement for water filter cartridges, we see a tumbling waterfall. The caption reads, "Like nature, Brita is beautifully simple." What kind of thinking is this? Is nature an objective reality that, in its beautiful simplicity, is unaffected by time, culture, and place? The word _nature _itself: what do we actually mean by it? These are some of the riveting questions examined by Peter Coates as he demonstrates that nature, like us, has a history of its own. Beginning (...) with Roman times, Coates investigates the ideological and material factors that have influenced human perceptions of, attitudes toward, and uses of nature—notably religion and ethics, science, technology, economics, gender, and ethnicity. Nature is seen among its rich panoply of meanings as a physical place, as the collective phenomena of the world, as an essence or principle that informs the workings of the world, as an inspiration and guide for people and a source of authority governing human affairs, and as the conceptual opposite of culture. By examining these aspects of nature, Coates leads us on a spectacular tour of the central intellectual forces of Western civilization. The book is essential reading for those who seek an understanding of the history of ideas and the role of nature in that history. (shrink)

The Claims of Common Sense investigates the importance of ideas developed by Cambridge philosophers between the World Wars for the social sciences concerning common sense, vague concepts and ordinary language. John Coates examines the thought of Moore, Ramsey, Wittgenstein and Keynes, and traces their common drift away from early beliefs about the need for precise concepts and a canonical notation in analysis. He argues that Keynes borrowed from Wittgenstein and Ramsey their reappraisal of vague concepts, and developed the novel (...) argument that when analysing something as complex as social reality, theory might be simplified by using concepts which lack sharp boundaries. Coates then contrasts this conclusion with the view shared by two contemporary philosophical paradigms - formal semantics and Continental post-structuralism - that the vagueness of ordinary language inevitably leads to interpretive indeterminacy. Developing a link between Cambridge philosophy and work on complexity, vague predicates and fuzzy logic, he argues that Wittgenstein's and Keynes's ideas on the economy of ordinary language present a mediating route for the social sciences between these philosophical paradigms.

Mathematical explanations are poorly understood. Although mathematicians seem to regularly suggest that some proofs are explanatory whereas others are not, none of the philosophical accounts of what such claims mean has become widely accepted. In this paper we explore Wilkenfeld’s suggestion that explanations are those sorts of things that generate understanding. By considering a basic model of human cognitive architecture, we suggest that existing accounts of mathematical explanation are all derivable consequences of Wilkenfeld’s ‘functional explanation’ proposal. We therefore argue that (...) the explanatory criteria offered by earlier accounts can all be thought of as features that make it more likely that a mathematical proof will generate understanding. On the functional account, features such as characterising properties, unification, and salience correlate with explanatoriness, but they do not define explanatoriness. (shrink)

Ambivalence is a form of inner volitional conflict that we experience as being irresolvable without significant cost. Because of this, very few of us relish feelings of ambivalence. Yet for many in the Western philosophical tradition, ambivalence is not simply an unappealing experience that's hard to manage. According to Unificationists--whose view finds its historical roots in Plato and Augustine and is ably defended by contemporary philosophers such as Harry Frankfurt and Christine Korsgaard--ambivalence is a failure of well-functioning agency. The reasons (...) for this, we're told, are threefold. First, it precludes agents from resolving their wills in a way that is necessary for autonomy. Second, it precludes agents from fully affirming their live and, in particular, from fully affirming the choices they make. As a result, ambivalence robs them of an important source of meaning. Finally, ambivalence causes agents to act in self-defeating ways. In so doing, they act without integrity. Ambivalence is thus seen as a threat to a trio of important agential goods, and as a result, it imperils the best forms of human agency. -/- Against the Unificationists, D. Justin Coates argues that ambivalence does not preclude volitional resolution or normatively significant forms of affirmation. Nor does it guarantee self-defeat. Consequently, ambivalence as such is no threat to autonomy, meaning, or integrity. In assessing these arguments, ambivalence is also revealed to have an important role in securing the very goods that unificationists contend it undermines. The reason for this is that each of these goods requires the agent to be normatively competent. But normative competence itself, Coates argues, often leads agents to be ambivalent. The best forms of human agency are therefore shown to be not only compatible with ambivalence but as regularly requiring it. Ambivalence is thus not a volitional defect, but a crucial constituent of well-functioning agency. (shrink)

We investigated whether mathematicians typically agree about the qualities of mathematical proofs. Between-mathematician consensus in proof appraisals is an implicit assumption of many arguments made by philosophers of mathematics, but to our knowledge the issue has not previously been empirically investigated. We asked a group of mathematicians to assess a specific proof on four dimensions, using the framework identified by Inglis and Aberdein (2015). We found widespread disagreement between our participants about the aesthetics, intricacy, precision and utility of the proof, (...) suggesting that a priori assumptions about the consistency of mathematical proof appraisals are unreasonable.

In this chapter, we consider the plausibility and consequences of the use of the term “honest errors” to describe the accidental killings of civilians resulting from the US military’s drone campaigns in Iraq, Syria, Afghanistan, and elsewhere. We argue that the narrative of “honest errors” unjustifiably excuses those involved in these killings from moral culpability, and reinforces long-standing, pernicious assumptions about the moral superiority of the US military and the inevitability of civilian deaths in combat. Furthermore, we maintain that, given (...) the knowledge-distorting practices within the US military’s organizational structure, few if any civilian deaths from drone strikes meet the criteria of a genuinely morally excusing “honest mistake”. Instead, these accidental killings often reflect objectionable attitudes of relative disregard for the safety of civilians. These attitudes are, we argue, sufficient to warrant the attribution of blame and moral responsibility, both with respect to certain individual actions and with respect to the US military as an institution. In light of this, we propose incorporating a Principle of the Moral Equality of Non-combatants into military assessments of what counts as “acceptable risk” to civilians. This would go some way, we argue, to redressing the ongoing injustice inflicted on the victims of civilian killings by the failure of the US military and US political leadership to take moral responsibility for unjustified civilian deaths.

Judith Jarvis Thomson famously argued that abortion is permissible even if we accept that a fetus qualifies as a person and possesses a right to life. The current paper presents two arguments that undermine Thomson’s position. First, the paper sketches a contractarian argument that explores Thomson’s violinist thought experiment from behind a veil of ignorance, which suggests that if we had an equal likelihood of being an unwanted fetus and a pregnant woman, it would be rational for us to oppose (...) abortion. Second, the paper discusses the hypothetical self-aborting fetus, a thought experiment that reverses the dependence relationship between a woman and a fetus. It is argued that in this scenario, where fetuses have agency of their own, Thomson’s position would counterintuitively prohibit a woman from temporarily curtailing the freedom of her fetus even to save her own life.

Does artificial intelligence (AI) pose existential risks to humanity? Some critics feel this question is getting too much attention, and want to push it aside in favour of conversations about the immediate risks of AI. These critics now include the journal Nature, where a recent editorial urges us to 'stop talking about tomorrow's AI doomsday when AI poses risks today.' We argue that this is a serious failure of judgement, on Nature's part. In science, as in everyday life, we expect (...) influential actors to consider the consequences of error. As the world's leading scientific journal, Nature is certainly an influential actor, especially so in the absence of robust global regulation of AI. Yet it has manifestly failed to consider the cost of error in this case. (shrink)

This article attempts to show that Heidegger’s phenomenology may shed light on political phenomena. It pursues this project by arguing that Heidegger’s phenomenology is an appropriation of Aristotle’s practical philosophy and his conceptualization of phronesis. I argue that, in Being and Time, Heidegger’s ‘circumspection’, which is a capacity for making sense of practical situations, is a translation of phronesis. Heidegger argues, though, that the sight of circumspection is foreshortened by the rules and norms of ‘the one’. In division 2, ‘conscience’ (...) becomes a sharpening of the vision of phronesis, which sees through the one. I then defend Heidegger’s appropriation of phronesis and argue that Heidegger’s concept of conscience, which takes up a critical stance toward plurality, may actually be a proper vision of practical wisdom under modern conditions. I substantiate this claim by turning to an unlikely source to bolster Heidegger’s reading of phronesis and the modern public, Hannah Arendt. (shrink)

We focus on the production of efficient descriptions of objects, actions and events. We define a type of efficiency, textual economy, that exploits the hearer’s recognition of inferential links to material elsewhere within a sentence. Textual economy leads to efficient descriptions because the material that supports such inferences has been included to satisfy independent communicative goals, and is therefore overloaded in the sense of Pollack [18]. We argue that achieving textual economy imposes strong requirements on the representation and reasoning used (...) in generating sentences. The representation must support the generator’s simultaneous consideration of syntax and semantics. Reasoning must enable the generator to assess quickly and reliably at any stage how the hearer will interpret the current sentence, with its (incomplete) syntax and semantics. We show that these representational and reasoning requirements are met in the SPUD system for sentence planning and realization. (shrink)

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)

The idea of philosophy as a 'way of life' is not a new one. From the first recorded philosophy by Plato, there has been a tradition of thinking about philosophy as pointing us towards the good life, happiness and an ethical existence. But where does this notion that philosophy has anything to offer in terms of guiding us in how to live and live well come from? In this first ever introduction to philosophy as a way of life, Matthew (...) Sharpe and Michael Ure take us us through the history of the idea from Plato and the Buddha to Foucault, Hadot and Zizek. They examine the kinds of practical exercises each thinker recommended and practiced to transform their philosophy into manners of living and acting. Philosophy as a Way of Life also examines the recent resurgence of thinking about philosophy as a practical, lived reality and why this ancient tradition still has so much relevance and power in the contemporary world.

In the last two decades, philosophy of neuroscience has predominantly focused on explanation. Indeed, it has been argued that mechanistic models are the standards of explanatory success in neuroscience over, among other things, topological models. However, explanatory power is only one virtue of a scientific model. Another is its predictive power. Unfortunately, the notion of prediction has received comparatively little attention in the philosophy of neuroscience, in part because predictions seem disconnected from interventions. In contrast, we argue that topological predictions (...) can and do guide interventions in science, both inside and outside of neuroscience. Topological models allow researchers to predict many phenomena, including diseases, treatment outcomes, aging, and cognition, among others. Moreover, we argue that these predictions also offer strategies for useful interventions. Topology-based predictions play this role regardless of whether they do or can receive a mechanistic interpretation. We conclude by making a case for philosophers to focus on prediction in neuroscience in addition to explanation alone. (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)

Nonsymbolic comparison tasks are commonly used to index the acuity of an individual's Approximate Number System (ANS), a cognitive mechanism believed to be involved in the development of number skills. Here we asked whether the time that an individual spends observing numerical stimuli influences the precision of the resultant ANS representations. Contrary to standard computational models of the ANS, we found that the longer the stimulus was displayed, the more precise was the resultant representation. We propose an adaptation of the (...) standard model, and suggest that this finding has significant methodological implications for numerical cognition research. (shrink)

People who believe they have greater efficacy to address climate change are more likely to engage in pro-environmental behaviour. To confront the climate crisis, it will therefore be essential to understand the processes through which climate change efficacy is promoted. Some interventions in the literature assume that efficacy emerges from analytic reasoning processes: that it is deliberative, verbal, conscious, and influenced by information and education. In the current paper, we critique this notion. We review evidence showing that climate change efficacy (...) perceptions are (a) associated with climate-related distress and threat, (b) prescribed by social norms, (c) associated with social desirability and identity-expressive concerns, (d) surprisingly difficult to change through explicit, verbal instruction, but (e) responsive to imagery. We conclude by examining applied implications of these five propositions and discuss why non-analytic processes might (ironically) be beneficial for sustaining green activism. (shrink)

In previous studies investigating entrainment and person perception, synchronized movements were found to enhance memory for incidental person attributes. Although this effect is robust, including in dance, the process by which it is actuated are less well understood. In this study, two hypotheses are investigated: that enhanced memory for person attributes is the result of (1) increased gaze time between in-tempo dancers, and/or (2) greater attentional focus between in-tempo dancers. To explore these possible mechanisms in the context of observing dance, (...) an eye-tracking study was conducted in which subjects watched videos of pairs of laterally positioned dancers; only one of the dancers was synchronized with the music, the other being asynchronous. The results were consistent with the first hypothesis—music-dance synchrony gives rise to increased visual inspection times. In addition, there was a preference for upper-body fixations over lower-body fixations across both synchronous and asynchronous conditions. A subsequent, single-dancer eye-tracking study investigated fixations across different body regions, including head, torso, legs and feet. Significantly greater dwell times were recorded for head than torso and legs; feet attracted significantly less dwell time than any other body region. Lastly, the study sought to identify dance gestures responsible for torso- and head-directed fixations. Specifically we asked whether there are features in dance that are specially designed to direct an observer’s gaze towards the face—the main “communicative portal” with respect to the transmission of intent, affect and empathy.
