Advocates of radical realist theories of legitimacy propose that political legitimation narratives are often void where they show signs of motivated reasoning. In a recent critique of the method, example cases have been put forward in which an analysis and critique of flawed justification narratives seems urgently called for, and yet motivated reasoning is absent. This, critics suggest, should deflate the prominence of motivated reasoning within the radical realism. I argue here that those cases are misconstrued. Motivated reasoning can either (...) be easily identified therein, or the cases are irrelevant to begin with. The issue with realism’s motivated reasoning connection is another: the explanatory direction of fit between epistemic circularity and motivated reasoning. The former explains the normative salience of the latter. Hence, I hope this intervention clarifies a misunderstood and underexplored aspect of contemporary radical realist theory and adds to the contextualisation of the psychology of motivated reasoning within normative social theory more broadly.

We argue that artificial networks are explainable and offer a novel theory of interpretability. Two sets of conceptual questions are prominent in theoretical engagements with artificial neural networks, especially in the context of medical artificial intelligence: Are networks explainable, and if so, what does it mean to explain the output of a network? And what does it mean for a network to be interpretable? We argue that accounts of “explanation” tailored specifically to neural networks have ineffectively reinvented the wheel. In (...) response to, we show how four familiar accounts of explanation apply to neural networks as they would to any scientific phenomenon. We diagnose the confusion about explaining neural networks within the machine learning literature as an equivocation on “explainability,” “understandability” and “interpretability.” To remedy this, we distinguish between these notions, and answer by offering a theory and typology of interpretation in machine learning. Interpretation is something one does to an explanation with the aim of producing another, more understandable, explanation. As with explanation, there are various concepts and methods involved in interpretation: Total or Partial, Global or Local, and Approximative or Isomorphic. Our account of “interpretability” is consistent with uses in the machine learning literature, in keeping with the philosophy of explanation and understanding, and pays special attention to medical artificial intelligence systems.

The character of computational modelling of cognition depends on an underlying theory of representation. Classical cognitive science has exploited the syntax/semantics theory of representation that derives from logic. But this has had the consequence that the kind of psychological explanation supported by classical cognitive science is " _conceptualist_: " psychological phenomena are modelled in terms of relations that hold between concepts, and between the sensors/effectors and concepts. This kind of explanation is inappropriate for the Proper Treatment of Connectionism.

A. W. Moore argues in this bold, unusual, and ambitious book that it is possible to think about the world from no point of view. His argument involves discussion of a very wide range of fundamental philosophical issues, including the nature of persons, the subject-matter of mathematics, realism and anti-realism, value, the inexpressible, and God. The result is a powerful critique of our own finitude.

Abstract‘Behavioural modernity’ isn’t what it used to be. Once conceived as an integrated package of traits demarcated by a clear archaeological signal in a specific time and place, it is now disparate, archaeologically equivocal, and temporally and spatially spread. In this paper we trace behavioural modernity’s empirical and theoretical developments over the last three decades, as surprising discoveries in the material record, as well the reappraisal of old evidence, drove increasingly sophisticated demographic, social and cultural models of behavioural modernity. We (...) argue, however, that some approaches to identifying and categorizing modernity have not kept up with this new picture. This is due to what we term ‘Rubicon expectations’: classificatory and interpretive practices which look for or assume clear demarcations in behavioural and cultural processes. We develop a philosophical account of ‘investigative disintegration’ to capture how our understanding of behavioural modernity has changed, and how Rubicon-based practices have become inadequate. Disintegration, in the form we analyse, occurs when scientists’ conception of a phenomenon shifts sufficiently to reshape an investigation’s epistemic structure. For behavioural modernity, the explanatory weight which once lay on identifying ‘switch-points’ in the innate suite of hominin cognitive capacities, lies now in understanding the social and demographic environments that were capable of sustaining and nourishing more complex material cultures. Finally, we argue that the phenomenon itself has not disintegrated to the point that we are left with no interesting explanandum: for all its mosaic, disparate nature, there are still good reasons for behavioural modernity to retain its central place in investigation of our species' origins.

There remains no consensus among social scientists as to how to measure and understand forms of information deprivation such as misinformation. Machine learning and statistical analyses of information deprivation typically contain problematic operationalizations which are too often biased towards epistemic elites' conceptions that can undermine their empirical adequacy. A mature science of information deprivation should include considerable citizen involvement that is sensitive to the value-ladenness of information quality and that doing so may improve the predictive and explanatory power of extant (...) models.

How can one ‘see’ the operationalization of contemporary visual culture, given the imperceptibility and apparent automation of so many processes and dimensions of visuality? Seeing – as a position from a singular mode of observation – has become problematic since many visual elements, techniques, and forms of observing are highly distributed through data practices of collection, analysis and prediction. Such practices are subtended by visual cultural techniques that are grounded in the development of image collections, image formatting and hardware design. (...) In this article, we analyze recent transformations in forms of prediction and data analytics associated with spectacular performances of computation. We analyze how transformations in the collection and accumulation of images as ensembles by platforms have a qualitative and material effect on the emergent sociotechnicality of platform ‘life’ and ‘perception’. Reconstructing the visual transformations that allow artificial intelligence assemblages to operate allows some sense of their heteronomous materiality and contingency. (shrink)

Political realists have argued that ‘the political’ is an autonomous domain with its own distinctive concepts, distinctive methodology, and distinctive ‘source of normativity’. I here explore the metanormative commitments of realism (of the radical realist branch, in particular) and question the viability of exploring the ontology of the normative altogether. I argue that the escape into the metanormative realm was something of a wrong turn within the realism debates – an intellectual error. My central argument, building on recent metatheoretical work (...) on normativity, is meant to discredit the sheer possibility of metanormative distinctness. If realists can neither prove metanormative, nor traditional, nor methodological distinctness, there is a valid question as to its standing. I speculate, perhaps realism is little more than a new semantic label for ‘continental’ practices of social analysis as they leak into the analytic tradition. But then again it can be argued that most contemporary continental thought, and certainly much of what passes as critical theory these days, is thoroughly moralist, anti-positivist, and postmodern, and those sentiments are not shared by radical realists, who are, or so I’ll argue, far more faithful to the modernist tradition of social theory.

Combining sociological evidence with the analytical tools of philosophy, Ethics, Money and Sport articulates and explores the main concerns about the way money has changed our experience of sports. Clearly written and illustrated by examples from major sports around the world, Ethics, Money and Sport enables students, researchers and policymakers - as well as anyone with an interest in the future of sport - to engage with this crucial debate.

This chapter offers an indirect defence of the Evansian conception of egocentric space, by showing how it resolves a puzzle concerning the unity of egocentric spatial perception. The chapter outlines several common assumptions about egocentric perspectival structure and argues that a subject’s experience, both within and across her sensory modalities, may involve multiple structures of this kind. This raises the question of how perspectival unity is achieved, such that these perspectival structures form a complex whole, rather than merely disunified set (...) of individually, distinctively structured experiences. The shortcomings of variety of accounts are considered: switch accounts ; sensory accounts; transformation accounts; and ultimate accounts. These shortcomings are addressed by a further kind of account provided by the Evansian conception – an agentive account – according to which egocentrically structured experiences present the world in relation to parts of a single thing, the body as a dynamic unity.

Thought experiments have played a pivotal role in many debates within ethics—and in particular within applied ethics—over the past 30 years. Nonetheless, despite their having become a commonly used philosophical tool, there is something odd about the extensive reliance upon thought experiments in areas of philosophy, such as applied ethics, that are so obviously oriented towards practical life. Herein I provide a moderate defence of their use in applied philosophy against those three objections. I do not defend all possible uses (...) of thought experiments but suggest that we should distinguish between legitimate and illegitimate uses. Their legitimate uses are determined not so much by the modal content of any actual thought experiment itself, but by the extent to which the argument in which it is nested follows basic tenets of informal logic and respects the fundamental contingency of applied ethical problems. In pursuing these ideas, I do not so much provide a set of criteria for their legitimate use, but more modestly present two significant ways in which their use can go awry. (shrink)

The Covid‐19 crisis has accelerated a trend toward burnout in health care workers, making starkly clear that burnout is especially likely when providing health care is not only stressful and sad but emotionally alienating; in such situations, there is no mental space for clinicians to experience authentic clinical empathy. Engaged curiosity toward each patient is a source of meaning and connection for health care providers, and it protects against sympathetic distress and burnout. In a prolonged crisis like Covid‐19, clinicians provide (...) care out of a sense of duty, especially the duty of nonabandonment. We argue that when duty alone is relied on too heavily, with fear and frustration continually suppressed, the risk of burnout is dramatically increased. Even before Covid‐19, clinicians often worked under dehumanizing and unjust conditions, and rates of burnout were 50 percent for physicians and 33 percent for nurses. The Covid‐19 intensification of burnout can serve as a wake‐up call that the structure of health care needs to be improved if we are to prevent the loss of a whole generation of empathic clinicians.

The paper proposes a novel solution to the problem of scope posed by natural language indefinites that captures both the difference in scopal freedom between indefinites and bona fide quantifiers and the syntactic sensitivity that the scope of indefinites does nevertheless exhibit. Following the main insight of choice functional approaches, we connect the special scopal properties of indefinites to the fact that their semantics can be stated in terms of choosing a suitable witness. This is in contrast to bona fide (...) quantifiers, the semantics of which crucially involves relations between sets of entities. We provide empirical arguments that this insight should not be captured by adding choice/Skolem functions to classical first-order logic, but in a semantics that follows Independence-Friendly Logic, in which scopal relations involving existentials are part of the recursive definition of truth and satisfaction. These scopal relations are resolved automatically as part of the interpretation of existentials. Additional support for this approach is provided by dependent indefinites, a cross-linguistically common class of special indefinites that can be straightforwardly analyzed in our semantic framework.

Campaigns highlighting the alleged incompatibility of the Islamic polity with principles of democratic self-governance are longstanding. The basic assumption of the incompatibalist proposition runs as follows: Political legitimacy in Muslim polities can be reduced to a principle of conformity with a set of divinely given rules and norms, the Sharīʿa, occasionally supplemented, and interpreted, by Islamic legal scholars and practitioners. In short, political Islam recognizes the Sharīʿa and Usūl al-fiqh (or, for the purposes of this essay, fiqh, for short) as (...) the Islamic polity’s foundations––those are deemed incompatible with democratic participation. In response, Mohammad Fadel (2018) has argued that the legal instrument of maṣlaḥa, which Fadel summarizes as considerations of the “public good” or “general interest,” can establish the democratic accountability mechanism that critics see missing in political authorities of Sharīʿa–grounded polities. Fadel supports this normative view with reference to some select classical Sunni jurisprudence, particularly the Usūl al-fiqh. I contest this view in two ways: Firstly, on a conceptual level, most thorough analyses of democracy acknowledge responsiveness and active involvement as fundamental components of democratic self-rule. Fadel’s idea of maṣlaḥa does not entirely align with this notion. Secondly, from a doctrinal standpoint, Fadel’s argument is confined solely within the classical Sunni context. That means, Fadel’s argument is contingent upon a significant departure from numerous (potentially the majority) sources within a comprehensive lineage of maṣlaḥa. (shrink)

The paper proposes the first unified account of deictic/sentence-external and sentence-internal readings of singular different . The empirical motivation for such an account is provided by a cross-linguistic survey and an analysis of the differences in distribution and interpretation between singular different , plural different and same (singular or plural) in English. The main proposal is that distributive quantification temporarily makes available two discourse referents within its nuclear scope, the values of which are required by sentence-internal uses of singular different (...) to be distinct, much as its deictic uses require the values of two discourse referents to be distinct. Thus, we take sentence-internal readings to be a form of ‘association with distributivity’ that is similar to association with focus. The contrast between singular different , plural different and same is explained in terms of several kinds of quantificational distributors that license their internal readings. The analysis is executed in a stack-based dynamic system couched in type logic, so we get compositionality in the usual Montagovian way. Quantificational subordination and dependent indefinites in various languages provide additional motivation for the account. Investigating the connections between items with sentence-internal readings and the quantificational licensors of these readings opens up a larger project of formally investigating (i) the typology of quantificational distributors and distributivity-dependent items and (ii) the fine-grained contexts of evaluation needed to capture this typological variation.

We explored the neural mechanisms allowing humans to report the subjective onset times of conscious events. Magnetoencephalographic recordings of neural oscillations were obtained while human subjects introspected the timing of sensory, intentional, and motor events during a forced choice task. Brain activity was reconstructed with high spatio-temporal resolution. Event-time introspection was associated with specific neural activity at the time of subjective event onset which was spatially distinct from activity induced by the event itself. Different brain regions were selectively recruited for (...) introspection of different event types, e.g., the bilateral angular gyrus for introspection of intention. Our results suggest that event-time introspection engages specific neural networks to assess the contents of consciousness. Subjective event times should therefore be interpreted as the result of complex interactions between introspection and experience networks, rather than as direct reproduction of the individual’s conscious state or as a mere post hoc interpretation.

This paper is concerned with representational explanations of how one experiences and acts with one’s body as an integrated whole. On the standard view, accounts of bodily experience and action must posit a corresponding representational structure: a representation of the body as an integrated whole. The aim of this paper is to show why we should instead favour the minimal view: given the nature of the body, and representation of its parts, accounts of the structure of bodily experience and action (...) need not appeal to a representation of the body as an integrated whole. The argument proceeds by distinguishing two kinds of explanatory roles for representations: standing-in for absent targets and structuring ambiguous sensory information concerning a target. Representations of body-parts are suited to fulfil both kinds of explanatory role, whereas a representation of the body as an integrated whole is only suited to fulfil the latter, as a means of coordinating representations of body-parts. It is then argued that the structure of the body can itself serve as a means of coordinating body-part representations, rendering representation of the body as an integrated whole explanatorily superfluous.

The history of economic thought witnessed several prominent economists who took seriously models and concepts in physics for the elucidation and prediction of economic phenomena. Econophysics is an emerging discipline at the intersection of heterodox economics and the physics of complex systems, with practitioners typically engaged in two overlapping but distinct methodological programs. The first is to export mathematical methods used in physics for the purposes of studying economic phenomena. The second is to export mechanisms in physics into economics. A (...) conclusion is drawn that physics transfer is often justified at the level of mathematical transfer but unjustified at the level of mechanistic transfer. (shrink)

SUMMARYThis paper offers practical guidance for empirical interpretation in the history of political thought, especially uncovering what authors meant and why they wrote what they wrote. I thus seek to fill a small but significant hole in our rather abstract methodological literature. To counter this abstraction, I draw not only on methodological theorising but also on actual practice—and on detective-work, a fruitful analogy. The detective analogy seeks to capture the intuition that we can potentially find right answers but must handle (...) fragmentary evidence that different people can plausibly read in different ways. Placing the focus on evidence, and on combining different types of evidence, suggests that orthodox categories like ‘contextualist’ and ‘Marxist’ too often accentuate differences between scholars. This paper instead highlights core principles that unite us—ideas that underpin good textual interpretation across all ‘schools of thought’. (shrink)

Wakley in 1846 called Grant “at once the most eloquent, the most accomplished, the most self-sacrificing, and the most unrewarded man in the profession.”128 I have shown some of the reasons why this was so, and I have suggested that his Lamarckism was one of a number of factors that served to alienate him from the conservative scientific community in the 1830's and 1840's. I have further shown the need for a fundamental rethinking of Grant's position in the history of (...) biology. There is little profit in seeing him as a precursor of Darwin. His importance lies as a teacher of philosophical anatomy and as the disseminator of Geoffroy's views in London. With the recent interest of historians in the emergence of a non-Paleyite approach to design in the 1830's (that is, an approach stemming from a unity of plan), a reassessment of Grant along these lines seems in order.Also, by understanding Grant's professional and transmutational threat, we can more fully appreciate the anti-Lamarckian ploys of leading scientists like Owen and Lyell. These scientific and social tactics reinforced the isolation Grant suffered as a result of his radical, materialistic, and antimonopolist views. Together with the laissez-faire arrangements at the joint-stock university, they led to his financial collapse — and to the decline of his scientific output that Darwin found so inexplicable. Beddoe described Grant as a disappointed man. “Alas!” wrote Wakley. “Who would be an English Cuvier?”129. (shrink)

In this paper I argue that split-brain syndrome is best understood within an extended mind framework and, therefore, that its very existence provides support for an externalist account of conscious perception. I begin by outlining the experimental aberration model of split-brain syndrome and explain both: why this model provides the best account of split-brain syndrome; and, why it is commonly rejected. Then, I summarise Susan Hurley’s argument that split-brain subjects could unify their conscious perceptual field by using external factors to (...) stand-in for the missing corpus callosum. I next provide an argument that split-brain subjects do unify their perceptual fields via external factors. Finally, I explain why my account provides one with an experimental aberration model which avoids the problems typically levelled at such views, and highlight some empirical predictions made by the account. The nature of split-brain syndrome has long been considered mysterious by proponents of internalist accounts of consciousness. However, in this paper I argue that externalist theories can provide a straightforward explanation of the condition. I therefore conclude that the ability of externalist accounts to explain split-brain syndrome gives us strong reason to prefer them over internalist rivals. (shrink)

In this article, I explore the ethical dimensions of same-sex reproduction achieved through epigenome editing—an innovative and transformative technique. For the first time, I analyse the potential normativity of this disruptive approach for reproductive purposes, focusing on its implications for lesbian couples seeking genetically related offspring. Epigenome editing offers a compelling solution to the complex ethical challenges posed by traditional gene editing, as it sidesteps genome modifications and potential long-term genetic consequences. The focus of this article is to systematically analyse (...) the bioethical issues related to the use of epigenome editing for same-sex reproduction. I critically assess the ethical acceptability of epigenome editing with reproductive purposes from multiple angles, considering harm perspectives, the comparison of ethical issues related to gene and epigenome editing, and feminist theories. This analysis reveals that epigenome editing emerges as an ethically acceptable means for lesbian couples to have genetically related children. Moreover, the experiments of a reproductive use of epigenome editing discussed in this article transcend bioethics, shedding light on the broader societal implications of same-sex reproduction. It challenges established notions of biological reproduction and prompts a reevaluation of how we define the human embryo, while poses some issues in the context of gender self-identification and family structures. In a world that increasingly values inclusivity and diversity, this article aims to reveal a progressive pathway for reproductive medicine and bioethics, as well as underscores the need for further philosophical research in this emerging and fertile domain.

Tailoring climate change messages to a particular spatial scale (e.g. a specific country or region) is often seen as an effective way to frame communication about climate change. Yet the empirical evidence for the effectiveness of this strategy is scarce, and little is known about how recipients react to spatially-framed climate change messages. To learn more about the effects and usefulness of different spatial frames as a communication and engagement tool, we conducted a study in which we presented members of (...) the general public with either a national or a global framing of climate change. In contrast to previous spatial-framing studies, the present research used semi-structured interviews – rather than survey questions – to obtain rich, in-depth information about participants’ views of climate change. Irrespective of the framing, participants revealed associations that were located at various spatial scales. Moreover, when participants talked about climate change, they repeatedly switched between different spatial scales, revealing patterns that were consistent with seeking to preserve existing beliefs and preferences. These findings improve our understanding of how the public represents climate change, and provide a novel explanation as to why simple spatial framing often fails to achieve the anticipated effects.

I sketch a line of thought about consciousness and physics that gives some motivation for the hypothesis that conscious observers deviate—perhaps only very subtly and slightly—from quantum dynamics. Although it is hard to know just how much credence to give this line of thought, it does add motivation for a stronger and more comprehensive programme of quantum experiments involving quantum observers.

In 1949, Richard Feynman published the essentials of his solution to the recalcitrant problems that plagued quantum theories of electrodynamics of his days. The main problem was that the theory, that was considered to be correct and often led to correct observable consequences, also implied that some quantities should be infinite, while by common sense or empirical evidence they were finite. Feynman devised a method of solving the relevant theoretical equations in which particular combinations of elementary solutions yielded empirically adequate (...) results even when applied to complex problems. The combination of the basic solutions was guided by relatively simple graphical considerations... (shrink)

There has been considerable discussion in the literature of one kind of identity problem that mathematical structuralism faces: the automorphism problem, in which the structure is unable to individuate the mathematical entities in its domain. Shapiro (Philos Math 16(3):285–309, 2008) has partly responded to these concerns. But I argue here that the theory faces an even more serious kind of identity problem, which the theory can’t overcome staying within its remit. I give two examples to make the point.

Beginning with Zagzebski (The Philosophical Quarterly 44:65–73, 1994), some philosophers have argued that there can be no solution to the Gettier counterexamples within the framework of a fallibilist theory of knowledge. If true, this would be devastating, since it is believed on good grounds that infallibilism leads to scepticism. But I argue here that these purported proofs are mistaken and that the truthmaker solution to the Gettier problems is both cogent and fallibilist in nature. To show this I develop the (...) notion of evidence of a state of affairs, a crucial concept in the truthmaker theory. I also argue that a common principle of the transmission of evidence through entailment is false, and the cause of much of the trouble. (shrink)

Two experiments used eyetracking during reading to examine the processing of the matrix verb following object and subject relative clauses. The experiments show that the processing of the matrix verb following an object relative is indeed slowed compared to the processing of the same verb following a subject relative. However, this difficulty is entirely eliminated if additional material intervenes between the object gap and the matrix verb. An explanation in terms of spillover processing is ruled out, suggesting that it is (...) the gap-matrix verb sequence that is itself responsible for the difficulty. We consider two accounts of this difficulty, one emphasizing the potential difficulty of rapidly switching between the sentential subject's thematic or syntactic role in the embedded clause and its role in the matrix clause, and one emphasizing the potential difficulty of performing two demanding memory retrievals in rapid succession. The present experiments also closely replicate the previous findings from eyetracking that the noun phrase and the verb within an object relative are both loci of processing difficulty, but that the former induces substantially greater difficulty.

Although it might seem to elicit only a marginal interest for philosophical inquiry, in 20th century continental philosophy the experience of solitude and loneliness were shown to have unexpected importance and gravity. For philosophers such as M. Heidegger, H. Arendt, H.-G. Gadamer or P. Sloterdijk, solitude and loneliness are to be seen, on the one hand, as an ontological determination of our Being and, on the other, as a cause for some of the most worrisome problems of our times such, (...) as the birth of totalitarianism or the phenomenon of self-alienation wide-spread in the Western bureaucratic societies. But none of the philosophers dealing with these matters offers us a clear positive understanding of what solitude and loneliness actually are nor what the task of philosophy should be with regard to these experiences even though they give us to understand that philosophy has one. The present paper tarries upon this question, approaching it from the other end though an investigation of the status of alterity in Heidegger and Gadamer’s philosophy. (shrink)

This edited collection presents the latest cutting-edge research in the philosophy and cognitive science of temporal illusions. Illusion and error have long been important points of entry for both philosophical and psychological approaches to understanding the mind. Temporal illusions, specifically, concern a fundamental feature of lived experience, temporality, and its relation to a fundamental feature of the world, time, thus providing invaluable insight into investigations of the mind and its relationship with the world. The existence of temporal illusions crucially challenges (...) the naïve assumption that we can simply infer the temporal nature of the world from experience. This anthology gathers eighteen original papers from current leading researchers in this subject, covering four broad and interdisciplinary topics: illusions of temporal passage, illusions and duration, illusions of temporal order and simultaneity, and the relationship between temporal illusions and the cognitive representation of time.

This paper advances a version of physicalism which reconciles the “a priori entailment thesis” (APET) with the analytic independence of our phenomenal and physical vocabularies. The APET is the claim that, if physicalism is true, the complete truths of physics imply every other truth a priori. If so, “cosmic hermeneutics” is possible: a demon having only complete knowledge of physics could deduce every truth about the world. Analytic independence is a popular physicalist explanation for the apparent “epistemic gaps” between phenomenal (...) and physical truths. The two are generally seen as incompatible, since the demon’s deductions seem to presuppose analytic connections between physical and phenomenal terms. I begin by arguing, in support of the APET, that implications from the complete truths of physics to phenomenal truths cannot be a posteriori. Such implications are (according to the physicalist) necessarily true. But they cannot be Kripke-style a posteriori necessities, since (according to the physicalist) the complete truths of physics fix any relevant a posteriori facts about the reference of terms. I then show how the physicalist can turn the tables: the demon can exploit the physical fixing of reference to bridge the gap between the vocabularies, by deducing when phenomenal and physical terms co-refer. This opens the way for a “type-C” physicalism, which accepts in-principle deducibility while still appealing to analytic independence to explain why we (who are not demons) find it impossible to see phenomenal-physical connections a priori.

My modest aim in this paper is to prove certain relations between some type of hyper-intensional operators, namely context shifting operators, and compositionality in natural languages. Various authors (e.g. von Fintel & Matthewson 2008; Stalnaker 2014) have argued that context-shifting operators are incompatible with compositionality. In fact, some of them understand Kaplan’s (1989) famous ban on context-shifting operators as a constraint on compositionality. Others, (e.g. Rabern 2013) take contextshifting operators to be compatible with compositionality but, unfortunately, do not provide a (...) proof, or an argument in favor of their position. The aim of this paper is to do precisely that. Additionally, I provide a new proof that compositionality for propositional content (intension) is a proper generalization of compositionality for character (hyper-intensions). (shrink)

It’s a truism of philosophy that Realists must not postulate more than we could reasonably hope to know, while Anti-Realists must not leave us with so little that all knowledge is impossible. But balance is not easily come by—and even less in philosophy than in life. So philosophy continues to struggle over the hard cases, with neither the Realist nor the Anti-Realist able to score an easy victory.

I give a brief introduction to how Feynman diagrams are used. I review arguments to the effect that they are only used as calculation tools and should not be interpreted as representations of physical processes. Against these arguments, I propose to regard Feynman diagrams as visual models that explain, in some respects, how elementary particles interact.

Enhanced weathering, in comparison to other geoengineering measures, creates the possibility of a reduced cost, reduced impact way of decreasing atmospheric carbon, with positive knock-on effects such as decreased oceanic acidity. We argue that ethical concerns have a place alongside empirical, political and social factors as we consider how to best respond to the critical challenge that anthropogenic climate change poses. We review these concerns, considering the ethical issues that arise (or would arise) in the large-scale deployment of enhanced weathering. (...) We discuss post-implementation scen- arios, failures of collective action, the distribution of risk and externalities and redress for damage. We also discuss issues surrounding ‘dirty hands’ (taking conventionally immoral action to avoid having to take action that is even worse), whether enhanced weathering research might present a moral hazard, the importance of international governance and the notion that the implementation of large-scale enhanced weathering would reveal problematic hubris. Ethics and scientific research interrelate in complex ways: some ethical considerations caution against research and implementation, while others encourage them. Indeed, the ethical perspective encourages us to think more carefully about how, and what types of, geoengineering should be researched and implemented. (shrink)

The two kinds of discrimination I want to talk about are political discrimination and cognitive discrimination. By political discrimination, I mean what we ordinarily understand by the term "discrimination" in political contexts: A manifest attitude in which a particular property of a person which is irrelevant to judgments of that person's intrinsic value or competence, for example his race, gender, class, sexual orientation, or religious or ethnic affiliation, is seen as a source of disvalue or incompetence; in general, as a (...) source of inferiority.By cognitive discrimination, I mean what we ordinarily understand by the term "discrimination" in cognitive contexts: A manifest capacity to distinguish veridically between one property and another, and to respond appropriately to each. I want to explore the relation between these two kinds of discrimination, and to argue that the first type of discrimination depends upon a failure of the second. (shrink)

Deep brain stimulation (DBS) has been proposed as a potential treatment of drug addiction on the basis of its effects on drug self-administration in animals and on addictive behaviours in some humans treated with DBS for other psychiatric or neurological conditions. DBS is seen as a more reversible intervention than ablative neurosurgery but it is nonetheless a treatment that carries significant risks. A review of preclinical and clinical evidence for the use of DBS to treat addiction suggests that more animal (...) research is required to establish the safety and efficacy of the technology and to identify optimal treatment parameters before investigating its use in addicted persons. Severely addicted persons who try and fail to achieve abstinence may, however, be desperate enough to undergo such an invasive treatment if they believe that it will cure their addiction. History shows that the desperation for a cure of addiction can lead to the use of risky medical procedures before they have been rigorously tested. In the event that DBS is used in the treatment of addiction, we provide minimum ethical requirements for clinical trials of its use in the treatment of addiction. These include: restrictions of trials to severely intractable cases of addiction; independent oversight to ensure that patients have the capacity to consent and give that consent on the basis of a realistic appreciation of the potential benefits and risks of DBS; and rigorous assessments of the effectiveness and safety of this treatment compared to the best available treatments for addiction.
