We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

ABSTRACTIlya Somin, like several other political epistemologists, effectively exposes the extent of public ignorance and the ways in which such ignorance may damage democratic outcomes. This underpins his case for a more streamlined state, leaving more to individual “foot voting”—where citizens are better incentivized to choose knowledgeably and rationally. One cannot dispute the fact of deep public ignorance. However, one can question the widespread assumption that ignorance is necessarily ethically significant, always productive of undesirable outcomes, or otherwise implicitly dangerous (...) for democracy. The sheer lack of individual efficacy in mass democracies not only incentivizes ignorance, but also creates conditions wherein such ignorance is individually harmless and unlikely in the aggregate to greatly contribute to one or another outcome. Beyond this, there may be no way to attain meaningful knowledge in the areas where democratic decision making is most fraught. Indeed, ignorance may at times lead to better outcomes than would knowledge. The seemingly unassailable status of democracy itself, and the valuable institutional stability that this status ensures, seem to be founded upon a bedrock of public ignorance as to the real nature of democracy.

It has been reported that behavior of experts and novices in various sporting tasks is impervious to the introduction of blur. However, studies have used diverse methods of blurring the visual stimulus, and tasks that did not always preserve the normal perception-action coupling. In the current study, we developed a novel experimental protocol to examine the effect of different levels of Gaussian blur on interception performance and eye gaze data using an immersive VR task. Importantly, this provided a realistic simulation (...) of a real-world boxing scenario in which expert combat athletes experienced a first-person, adaptive viewpoint of the visual environment, which could be blurred according to their gaze location. We found that participants exhibited similar interception performance in the presence of central blur or peripheral blur compared to a control condition with no blur. However, interception performance was significantly better with a central blur compared to peripheral blur. Eye gaze data indicated that although participants fixated at similar areas of interest irrespective of the presence of blur, fixation duration was significantly longer with a strong level of blur in the peripheral viewing condition than all levels of central blur and the control condition. These findings can be explained by relocating attention to different areas of the environment, which thereby influenced the perception of salient information. Participants also performed better on the first punch of a sequence preceded by a foot feint compared to arm feint or no feint. Still, irrespective of feint type, performance was significantly better on the second and third punch compared to the first punch. These findings are consistent with participants using additional information from the opponent's body movements and situational probabilities to increase performance as the sequence of punches developed. Overall, these are the first evidence for the use of VR as a means to examine gaze-contingent manipulations of the environment, and hence highlight the potential for facilitating learning and transfer to a real sporting situations.

This fitting Festschrift contains twelve essays by students, colleagues and friends of Philippa Foot, all of them leading figures in philosophy. Some deal directly and even centrally with Foot’s own work, the others with topics she has herself written on and in a manner relatively sympathetic to what she has said about those topics. Foot’s interests in ethics have been fairly wide-ranging, and that fact is well reflected in the essays of the present volume. Elizabeth Anscombe writes (...) on ‘Practical Inference’; Simon Blackburn on ‘The Flight to Reality’; Rosalind Hursthouse on ‘Applying Virtue Ethics’; Anthony Kenny on ‘Philippa Foot on Double Effect’; Gavin Lawrence on ‘The Rationality of Morality’; John McDowell on ‘Two Sorts of Naturalism’; Warren Quinn on ‘Putting Rationality in its Place’; David Sachs on ‘Notes on Unfairly Gaining More: Pleonexia’; Thomas Scanlon on ‘Fear of Relativism’; Michael Thompson on ‘The Representation of Life’; David Wiggins on ‘Categorical Requirements: Kant and Hume on the Idea of Duty’; and Bernard Williams on ‘Acts and Omissions: Doing and Not Doing’. A short review cannot hope to do justice to all the interesting (and controversial) material to be found in these dedicatory essays. And rather than attempt to discuss even two or three of them, I think it better to choose a single one for closer consideration, namely, Warren Quinn’s rich and fascinating critique of subjectivist/instrumentalist views of practical reason.

This volume of essays in honour of Philippa Foot constitutes a high quality Festschrift. There is no doubt that Philippa Foot's career is worthy of such a volume. She is one of the most influential philosophers of the past few decades and her work has given rise to, and seeded, much debate in contemporary moral philosophy. She has written on a wide variety of topics — virtue ethics, the doctrine of double effect, naturalism, and practical reasoning. The essays (...) in this volume touch on all of these issues. They are written by such distinguished philosophers as G. E. M. Anscombe, Simon Blackburn, Rosalind Hursthouse, Anthony Kenny, Gavin Lawrence, John McDowell, Warren Quinn, David Sachs, T. M. Scanlon, Michael Thompson, David Wiggins, and Bernard Williams. They all succeed in honouring Professor Foot's work. Given space considerations, and considering the forum for this review, I will focus on those essays that are of most relevance to consequentialism. (shrink)

This chapter outlines three programs that aim to use biological insights in support of philosophical positions in ethics: Aristotelian approaches found, for example, in Thomas Hurka and Philippa Foot; Humean approaches found in Simon Blackburn and Allan Gibbard; and biologically grounded approaches found in of Elliott Sober and Brian Skyrms. The first two approaches begin with a philosophical view, and seek support for it in biology. The third approach begins with biology, and uses it to illuminate the status (...) of morality. This chapter pursues a version of the third program. A major accomplishment of evolutionary biology has been the explanation of biological altruism, which opens the door to a similar explanation of psychological altruism, or “fellow-feeling.” The chapter conjectures that humans have evolved a capacity for normative governance by socially shared rules. A process of cultural evolution led to the social rules with which we are familiar. This genealogical story poses a challenge, for the idea of moral truth plays no role in it. The story therefore lends support to non-cognitivism or anti-realist expressivism. The chapter concludes by exploring the implications of the genealogical story for moral knowledge, moral objectivity, and the idea of moral authority. (shrink)

In a lot of domains in metaphysics the tacit assumption has been that whichever metaphysical principles turn out to be true, these will be necessarily true. Let us call necessitarianism about some domain the thesis that the right metaphysics of that domain is necessary. Necessitarianism has flourished. In the philosophy of maths we find it held that if mathematical objects exist, then they do of necessity. Mathematical Platonists affirm the necessary existence of mathematical objects (see for instance Hale and Wright (...) 1992 and 1994; Wright 1983 and 1988; Schiffer 1996; Resnik 1997; Shapiro 1997 and Zalta 1988) while mathematical nominalists, usually in the form of fictionalists, hold that necessarily such objects fail to exist (see for instance Balaguer 1996 and 1998; Rosen 2001 and Yablo 2005). In metaphysics more generally, until recently it was more or less assumed that whatever the right account of composition—the account of under what conditions some xs compose a y—that account will be necessarily true (for a discussion of theories of composition see Simons 1987 and van Inwagen 1987 and 1990; the modal status of the composition relation is explicitly addressed in Schaffer 2007; Parsons 2006 and Cameron 2007). Similarly, it has generally been assumed that whatever the right account is of the nature of properties, whether they be universals, tropes, or whether nominalism is true, that account will be necessarily true (though see Rosen 2006 for a recent suggestion to the contrary). In considering theories of persistence it has been widely held that whether objects endure or perdure through time is a matter of necessity (Sider 2001; though see Lewis 1999 p227 who defends contingent perdurantism). And with respect to theories of time it is frequently held that whichever of the A- or B-theory is true is necessarily true. A-theorists often argue that there is time in a world only if the A-theory is true at that world (see for instance McTaggart 1903; Markosian 2004; Bigelow 1996; Craig 2001) while B-theorists often argue that the A-theory is internally inconsistent (Smart 1987; Mellor 1998; Savitt 2000 and Le Poidevin 1991). Once again, we find a few recent contingentist dissenters. Bourne (2006) suggests that it is a contingent feature of time that it is tensed, and thus that the A-theory is contingently true. Worlds in which there exist only B-theoretic properties are worlds with time, it is just that time in those worlds time is radically different to the way it is actually. Other defenders of the B-theory, though not expressly contingentists, do offer arguments against versions of the A-theory that try to show that such A-theories theories are inconsistent with the actual laws of nature (see for instance Saunders 2002 and Callender 2000); these arguments, at least, leave room for the possibility that the A-theories in question are contingently false (at least on the assumption that the laws of nature are themselves contingent, an assumption that not everyone accepts). Despite some notable exceptions, necessitarianism has flourished in many, if not most, domains in metaphysics. One such exception is Lewis’ famous defence of Humean supervenience as a contingent claim about our world. Lewis does not argue that necessarily, the supervenience base for all matters of fact in a world is nothing but a vast mosaic of local matters of particular fact. Rather, he thinks that we have reason to think that our world is one in which Humean supervenience holds (see Lewis 1986 p9-10 and 1994). Another exception to the necessitarian orthodoxy is to be found in the lively debate about the modal status of the laws of nature. Here, if anything, contingentism has been the dominating force, with it generally being held that there are possible worlds in which different laws of nature hold (this view is defended by, among others, Lewis 1986 and 2010; Schaffer 2005 and Sidelle 2002). Necessitarian dissenters hold that the laws of nature are necessary, frequently because they think it is necessary that fundamental properties have the causal or nomic profiles they do (see for instance Shoemaker 1980 and 1988; Swoyer 1982; Bird 1995; Ellis and Lierse 1994). Nevertheless, when it comes to thinking about the nature of the laws themselves, the necessitarian presumption is back on firm footing. Though there is disagreement about whether the laws are generalisations that feature in the most virtuous true axiomatisation of all the particular matters of fact (often known as the Humean view of laws and defended by Ramsey 1978; Lewis 1986 and Beebee 2000) or whether laws are relations of necessity that hold between universals (a view defended by Armstrong 1983; Dretske 1977; Tooley 1977 and Carroll 1990) no one has seriously suggested that it might be a contingent matter which of these is the right account of laws. The necessitarian orthodoxy is not surprising since metaphysics is largely an a priori process. While a priori reasoning may be used to determine whether a proposition is necessary or contingent, it is not well placed (in the absence of a posteriori evidence) to determine whether a contingent proposition is actually true or false. Since metaphysicians aim to tell us which principles are true in which worlds, on the face of it the discovery that metaphysical principles are contingent seems to make part of the task of metaphysics epistemically intractable. In what follows I consider two reasons one might end up embracing contingentism and whether this would lead one into epistemic difficulty. The following section considers a route to contingent metaphysical truths that proceeds via a combination of conceptual necessities and empirical discoveries. Section 3 considers whether there might be synthetic contingent metaphysical truths, and the final section raises the question of whether if there were such truths we would be well placed to come to know them.

The chapter offers a philosophical account of the capacity to recognise moral considerations to be used in investigating whether psychopaths are amoral, as opposed to immoral. The author criticizes Simon Baron-Cohen and James Blair et al., who maintain that psychopaths are amoral insofar they lack empathy, for endorsing a sentimentalist account of moral understanding. Moreover, the author criticizes Kant's version of rationalism for assuming an impersonal notion of moral rationality that is unconstrained by specific human features. He offers, instead, (...) an account of moral rationality in the spirit of Philippa Foot's Aristotelian inspired proposal. According to this view, moral rationality is a type of rationality that depends on the capacities for empathy, developing feelings of benevolence and resistance to causing harm. Although some psychopaths are irrational in other ways, the author suggest that central to psychopathy is a failure of moral rationality. (shrink)

The late J. L. Mackie and his work were a focus for much of the best philosophical thinking in the Oxford tradition. His moral thought centres on that most fundamental issue in moral philosophy – the issue of whether our moral judgements are in some way objective. The contributors to this volume, first published in 1985, are among the most distinguished figures in moral philosophy, and their essays in tribute to John Mackie present views at the forefront of the subject. (...) Five of the essays give a new understanding of the objectivity of moral judgements. These are by Simon Blackburn, R.M. Hare, John McDowell, Susan Hurley and Bernard Williams. The remaining contributors – Philippa Foot, Steven Lukes, Amartya Sen, David Wiggins – give their attention to problems which are equally compelling, such as the defence of a moral outlook based on a conception of a need and of what follows from it. The volume also includes the addresses given by Simon Blackburn and George Cawkwell at the memorial service for John Mackie, and a list of his publications, compiled by Joan Mackie. (shrink)

This paper defends an account of cosmopolitanism as a corrective virtue of the sort endorsed by Philippa Foot. In particular, it argues that cosmopolitanism corrects a common and dangerous tendency to form overly strong identifications with political entities such as countries, nations, and cultures. The account helps to unify the current heterogeneous collection of cosmopolitan theories, as is illustrated by a discussion of the cultural cosmopolitanism of Jeremy Waldron, and the political cosmopolitanism of Simon Keller. The account also (...) helps distinguish cosmopolitans from their critics, most of whom share the cosmopolitan’s commitment to respect for human rights: for example, liberal patriots, liberal nationalists and liberal culturalists.

Climate change is projected to have very severe impacts on future generations. Given this, any adequate response to it has to consider the nature of our obligations to future generations. This paper seeks to do that and to relate this to the way that inter-generational justice is often framed by economic analyses of climate change. To do this the paper considers three kinds of considerations that, it has been argued, should guide the kinds of actions that one generation should take (...) if it is to treat both current and future people equitably. In particular it examines the case for what has been termed pure time discounting, growth discounting and opportunity cost discounting; and it assesses their implications for climate policy. It argues that none of these support the claims of those who think they give us reason to delay aggressive mitigation policies. It also finds, however, that the second kind of argument can, in certain circumstances, provide support for passing on some of the costs of mitigation to future generations. (shrink)

I argue that it is rational for a person to believe the conjunction of her beliefs. This involves responding to the Lottery and Preface Paradoxes. In addition, I suggest that in normal circumstances, what it is to believe a conjunction just is to believe its conjuncts.

I argue that alternative-denoting expressions interact with their semantic context by taking scope. With an empirical focus on indefinites in English, I show how this approach improves on standard alternative-semantic architectures that use point-wise composition to subvert islands, as well as on in situ approaches to indefinites more generally. Unlike grammars based on point-wise composition, scope-based alternative management is thoroughly categorematic, doesn’t under-generate readings when multiple sources of alternatives occur on an island, and is compatible with standard treatments of binding. (...) Unlike all in situ treatments of indefinites, relying on a true scope mechanism prevents over-generation when an operator binds into an indefinite. My account relies only on function application, some mechanism for scope-taking, and two freely-applying type-shifters: the first is Karttunen’s :3–44, 1977. https://doi.org/10.1007/BF00351935) proto-question operator, aka Partee’s Studies in discourse representation theory and the theory of generalized quantifiers, Foris, Dordrecht, 1986) IDENT, and the second can be factored out of extant approaches to the semantics of questions in the tradition of Karttunen. These type-shifters form a decomposition of LIFT, the familiar function mapping values into scope-takers. Exceptional scope of alternative-generating expressions arises via scopal pied-piping: indefinites take scope over their island, which then itself takes scope. (shrink)

In this paper I use philosophical accounts on the relationship between trust and knowledge in science to apprehend this relationship on the Web. I argue that trust and knowledge are fundamentally entangled in our epistemic practices. Yet despite this fundamental entanglement, we do not trust blindly. Instead we make use of knowledge to rationally place or withdraw trust. We use knowledge about the sources of epistemic content as well as general background knowledge to assess epistemic claims. Hence, although we may (...) have a default to trust, we remain and should remain epistemically vigilant; we look out and need to look out for signs of insincerity and dishonesty in our attempts to know. A fundamental requirement for such vigilance is transparency: in order to critically assess epistemic agents, content and processes, we need to be able to access and address them. On the Web, this request for transparency becomes particularly pressing if (a) trust is placed in unknown human epistemic agents and (b) if it is placed in non-human agents, such as algorithms. I give examples of the entanglement between knowledge and trust on the Web and draw conclusions about the forms of transparency needed in such systems to support epistemically vigilant behaviour, which empowers users to become responsible and accountable knowers.

This paper defends an egalitarian conception of global justice against two kinds of criticism. Many who defend egalitarian principles of justice do so on the basis that all humans are part of a common 'association' of some kind. In this paper I defend the humanity-centred approach which holds that persons should be included within the scope of distributive justice simply because they are fellow human beings. The paper has four substantive sections - the first addresses Andrea Sangiovanni's reciprocity-based argument for (...) the claim that egalitarian principles apply only within the state. The second responds to Michael Blake's coercion-based argument for the thesis that egalitarian principles apply only within the state. A third section draws attention to a general problem with associational accounts of distributive justice. Finally, I seek to show how a humanity-centred cosmopolitanism can accommodate the insights associated with an associational approach. (shrink)

This paper uses the example of the COVID-19 pandemic to analyse the danger associated with insufficient epistemic pluralism in evidence-based public health policy. Drawing on certain elements in Paul Feyerabend’s political philosophy of science, it discusses reasons for implementing more pluralism as well as challenges to be tackled on the way forward.

In this paper I study dynamical models of rational deliberation within the context of Newcomb's problem. Such models have been used to argue against the soundness of the "tickle'" defense of evidential decision theory, which is based on the idea that sophisticated decision makers can break correlations between states and acts by introspecting their own beliefs and desires. If correct, this would show that evidential decision theory agrees with the recommendations of causal decision theory. I argue that an adequate understanding (...) of rational deliberation leads to deliberative processes for which this idea works. My proposal is modest, though. Evidential decision theory cannot always be reconciled with causal decision theory along the lines suggested here, but the agreement between the two theories is broader than previously thought.

Environmentalist philosophers often paint a holistic picture, stressing such things as the continuity of humanity with wider nature and our membership of the 'natural community' . The implication seems to be that a non-anthropocentric philosophy requires that we strongly identify ourselves with nature and therefore that we downplay any human/non-human distinction. An alternative view, I think more interesting and plausible, stresses the distinction between humanity and a nature valued precisely for its otherness. In this article I discuss some of its (...) main elements, and some of the difficulties involved with keeping nature's otherness in focus. Firstly (in sections 1-5), I try to clarify what I take to be the otherness-based position by distinguishing it from the apparently similar views of John Passmore, Robert Elliott and Keekok Lee, and some opposed holistic views, especially of J. Baird Callicott. Then, in the second half of the article (sections 6-7), I argue that if nature is valued in virtue of its otherness, this value is best thought of as an extrinsic, final and objective good, where 'objectivity' is a 'method of understanding', in Thomas Nagel's sense. Although I give some reasons for preferring an otherness account to certain alternative positions, I make no overall attempt to 'prove' that nature is valuable for its otherness. My aim is to show that, if it is, then this seems the best way to understand that value. (shrink)

Memes, of the kind found often on the internet, are an increasingly significant medium of expressive activity. I develop a theory of their ontological nature and, in parallel, an analysis of the concept meme. On my view, memes are abstract artifacts made out of norms for production of instances. The norms say things like ‘use a certain image; add text of a certain kind; the text should be delivered in two chunks, one at the top of the image, one at (...) the bottom, etc.’ Instances of these memes are created when users follow these norms and publish the results. The concept meme is analyzed in terms of the notion of memographic practice, a historically situated form of activity within which memes are created and their instances produced and made public.

One of the main contributions of Richard Bradley’s book is an elegant extension of Jeffrey’s Logic of Decision that countenances the evaluation of conditional prospects. This extension offers a promising new setting in which to model dynamic choice. In Bradley’s framework, plans can be understood as conditionals of an appropriate sort, while dynamic consistency can be viewed as providing a constraint on the evaluation of conditionals across time. In this paper, we study connections between planning conditionals and dynamic consistency.

The main purpose of this paper is to refute the metaphysicians ‘methodological continuation’ argument supporting epistemic realism in metaphysics. This argument aims to show that scientific realists have to accept that metaphysics is as rationally justified as science given that they both employ inference to the best explanation, i.e. that metaphysics and science are methodologically continuous. I argue that the reasons given by scientific realists as to why inference to the best explanation is reliable in science do not constitute a (...) reason to believe that it is reliable in metaphysics. The justification of IBE in science and the justification of IBE in metaphysics are two distinct issues with only superficial similarities, and one cannot rely on one for the other. This becomes especially clear when one analyses the debate about the legitimacy of IBE that has taken place between realists and empiricists. The metaphysician seeking to piggyback on the realist defense of IBE in science by the methodological continuation argument presupposes that the defense is straightforwardly applicable to metaphysics. I will argue that it is, in fact, not. The favoured defenses of IBE in scientific realism make extensive use of empirical considerations, predictive power and inductive evidence, all of which are paradigmatically absent in the metaphysical context. Furthermore, I argue that the metaphysician, even if the realist would concede to the methodological continuation argument, fails to offer any agreed upon conclusions resulting from its application in metaphysics. As a result, the scientific realist is not committed to believing that there is metaphysical knowledge. (shrink)

This volume comprises ten original essays on Nietzsche, one of the western canon's most controversial ethical thinkers. An international team of experts clarify Nietzsche's own views, both critical and positive, ethical and meta-ethical, and connect his philosophical concerns to contemporary debates in and about ethics, normativity, and value.

In considering the debate about the meaning of ‘disease’, the positions are generally presented as falling into two categories: naturalist, e.g., Boorse, and normativist, e.g., Engelhardt and many others. This division is too coarse, and obscures much of what is going on in this debate. I therefore propose that accounts of the meaning of ‘disease’ be assessed according to Hare’s (1997) taxonomy of evaluative terms. Such an analysis will allow us to better understand both individual positions and their inter-relationships. Most (...) importantly, it will show that it is unlikely that there is a single unique disease-concept at issue. Rather, different authors are, for the most part, considering different concepts.

I address the usefulness of thinking about a human right to subsistence within conceptions of human rights grounded in ordinary moral reasoning. I argue that that natural rights should be understood as rights in rem, with their dynamism constrained by the requirements of justification and their scope constrained by the distinction between perfect and imperfect duty. I then suggest that many of the most pressing demands which the moral significance of subsistence needs create are plausibly imperfect duties, and so cannot (...) correlate to a natural right to subsistence. This restricts the helpfulness of a human right to subsistence in our reasoning about what we owe to others. (shrink)

Some find it plausible that a sufficiently long duration of torture is worse than any duration of mild headaches. Similarly, it has been claimed that a million humans living great lives is better than any number of worm-like creatures feeling a few seconds of pleasure each. Some have related bad things to good things along the same lines. For example, one may hold that a future in which a sufficient number of beings experience a lifetime of torture is bad, regardless (...) of what else that future contains, while minor bad things, such as slight unpleasantness, can always be counterbalanced by enough good things. Among the most common objections to such ideas are sequence arguments. But sequence arguments are usually formulated in classical logic. One might therefore wonder if they work if we instead adopt many-valued logic. I show that, in a common many-valued logical framework, the answer depends on which versions of transitivity are used as premises. We get valid sequence arguments if we grant any of several strong forms of transitivity of 'is at least as bad as' and a notion of completeness. Other, weaker forms of transitivity lead to invalid sequence arguments. The plausibility of the premises is largely set aside here, but I tentatively note that almost all of the forms of transitivity that lead to valid sequence arguments seem intuitively problematic. Still, a few moderately strong forms of transitivity that might be acceptable lead to valid sequence arguments, although weaker statements of the initial value claims avoid these arguments at least to some extent.

Recently, amid growing awareness that computer algorithms are not neutral tools but can cause harm by reproducing and amplifying bias, attempts to detect and prevent such biases have intensified. An approach that has received considerable attention in this regard is the Value Sensitive Design (VSD) methodology, which aims to contribute to both the critical analysis of (dis)values in existing technologies and the construction of novel technologies that account for specific desired values. This article provides a brief overview of the key (...) features of the Value Sensitive Design approach, examines its contributions to understanding and addressing issues around bias in computer systems, outlines the current debates on algorithmic bias and fairness in machine learning, and discusses how such debates could profit from VSD-derived insights and recommendations. Relating these debates on values in design and algorithmic bias to research on cognitive biases, we conclude by stressing our collective duty to not only detect and counter biases in software systems, but to also address and remedy their societal origins.

This article argues against the long-enduring practice of Josephan scholarship to treat the termsτύραννος(‘tyrant’) andλῃστής(‘brigand’) as a collocation, or as undistinguished terms of invective employed by Josephus against various Jewish antagonists in hisBellum Judaicum(=BJ). Towards this aim, the article first examines the frequency in which these two terms appear together throughout the text of theBJ, before turning to a critical examination of particular passages that feature the terms, in order to prove that they are, in fact, not used as undistinguished (...) terms of invective but as terms pertaining to two distinct classes of people: renegade aristocrats vying with their peers for absolute power (the ‘tyrants’) and their gangs of foot soldiers comprising men from the lower classes (the ‘brigands’). The article concludes that Josephus used these terms in this manner in order to convey to his readership, which largely consisted of Roman aristocrats, that the ringleaders of the Judaean revolt which raged betweena.d.66–73 were akin to renegades who periodically wreaked havoc on Rome's own aristocracy, often with devastating consequences for class and country alike.

This paper contrasts two ways of understanding the function of human thought and language. According to representationalism, the function of thought and language is to refer to entities in the world and assert truths about them. By contrast, pragmatism seeks to understand the function of thought and language without any such appeal, at the most fundamental level, to the concepts of truth or reference.

This study analyses the sensitivity of public goods contributions through the lens of psychological motives. We report the results of a public goods experiment in which subjects were induced with the motives of care and anger through autobiographical recall. Subjects’ preferences, beliefs, and perceptions under each motive are compared with those of subjects experiencing a neutral autobiographical recall control condition. We find, but only for those subjects with the highest comprehension of the game, that care elicits significantly higher contributions than (...) anger, with the control treatment in between. This positive influence of the care motive on unconditional giving is accounted for partly by preferences for giving and partly by beliefs concerning greater contributions by others. Anger also affects attention to own and other’s payoffs and perceptions of the game’s incentive structure. (shrink)

This paper is about how we should evaluate our tendencies to find – or fail to find – different meanings in the natural world. It has three aims: (1) to show that some virtues and vices can be exhibited in our tendencies to find or to overlook the meanings of natural things, even if it is unclear whether any can only be exhibited in our relations with such things; (2) to categorise some of the relevant virtues and vices; and (3) (...) to refute the objection that meaning-focused approaches to environmental philosophy, of the sort adopted by writers such as Alan Holland and myself, cannot adequately account for nature's independence from human concerns.
