Humanity will face water scarcity as this century progresses. Water use grew twice as fast as the global human population last century, and an increasing number of regions around the world are facing, or will face, freshwater scarcity. Four billion people face water scarcity at least one month out of the year. Scarcity makes water valuable for privatizers and commodifiers as an investment vehicle; it emboldens the currency of commodification. I will argue for water justice as socioenvironmental justice. The injustices (...) that can and do attach to water are not reducible to merely distributional wrongs or injustices, they are moral and political harms as markers of a failing democracy; water injustice, then, is a structural harm. I build on the literature of power dynamics from Iris Marion Young and David Schlosberg and argue that water injustice is structural and involves mis- and malrecognition and participation; moreover, I introduce the argument that water justice is participatory, a method of development that walks in lockstep with reflexive and discursive democracy.

Can shifting to tidal time potentially slow the catastrophic realities of sea-level rise? Sarah Cameron Sunde’s 36.5 / A Durational Performance with the Sea is a site-specific performance during which Sunde stands in a tidal bay for a full cycle as water engulfs her body and then reveals it again. The public participates. What began in 2013 as a poetic impulse has grown into a complex series of nine durational performances involving communities around the world. In this article, durational (...) performance artist and scholar Raegan Truax gleans insight from Indigenous feminist scholars and Indigenous women-led movements to analyse the choreographic and temporal dynamics of 36.5. Co-writing with the artist, and focusing specifically on Sunde’s durational shift to tidal time, Truax proposes a phenomenological undoing: ‘becoming Sea-swallowed’ as essential to the speculative possibility of ‘becoming otherwise’.

ABSTRACT:Deliberative democratic theory, commonly used to explore questions of “political” corporate social responsibility, has become prominent in the literature. This theory has been challenged previously for being overly sanguine about firm profit imperatives, but left unexamined is whether corporate contexts are appropriate contexts for deliberative theory in the first place. We explore this question using the case of Starbucks’ “Race Together” campaign to show that significant challenges exist to corporate deliberation, even in cases featuring genuinely committed firms. We return to (...) the underlying social theory to show that this is not an isolated case: for-profit firms are predictably hostile contexts for deliberation, and significant normative and strategic problems can be expected should deliberative theory be imported uncritically to corporate contexts. We close with recent advances in deliberative democratic theory that might help update the PCSR project, and accommodate the application of deliberation to the corporate context, albeit with significant alterations.

Gender dysphoria is a clinically significant incongruence between expressed gender and assigned gender, with rapidly growing prevalence among children. The UK High Court recently conducted a judicial review regarding the service provision at a youth-focussed gender identity clinic in Tavistock. The high court adjudged it ‘highly unlikely’ that under-13s, and ‘doubtful’ that 14–15 years old, can be competent to consent to puberty blocker therapy for GD. They based their reasoning on the limited evidence regarding efficacy, the likelihood of progressing to (...) cross-sex hormone therapy and the ‘life-changing consequences’ of puberty blockers. In this article, I offer two concurrent arguments to dispute their reasoning. First, I argue that minors can be competent to consent to puberty blockers for GD, because the decision to undergo puberty blocker therapy is no more complex or far-reaching than other medical decisions that we accept a child should be able to make. Second, I argue that—irrespective of competence—such legal restriction for all children fundamentally contradicts the central ethical tenet of child healthcare: best interests. For these two reasons, the high court should not restrict access to puberty blockers for competent GD children. (shrink)

Ross P. Cameron argues that the flow of time is a genuine feature of reality. He suggests that the best version of the A-Theory is a version of the Moving Spotlight view, according to which past and future beings are real, but there is nonetheless an objectively privileged present. Cameron argues that the Moving Spotlight theory should be viewed as having more in common with Presentism than with the B-Theory. Furthermore, it provides the best account of truthmakers for (...) claims about what was or will be the case. Cameron goes on to defend an account of the open future, and argues that this is a better account than that available to the Growing Block theory. (shrink)

The mental competence of people requesting aid-in-dying is a key issue for the how the law responds to cases of assisted suicide. A number of cases from around the common law world have highlighted the importance of competence in determining whether assistants should be prosecuted, and what they will be prosecuted for. Nevertheless, the law remains uncertain about how competence should be tested in these cases. This article proposes a test of competence that is based on the existing common law (...) but which is tailored to cases of assisted suicide. The test will help doctors, other health professionals and lawyers determine whether the suicidal person was able to competently request assistance. Such knowledge will help to reduce some of the current uncertainty about criminal liability in cases of assisted suicide. (shrink)

I consider David Efird and Tom Stoneham's recent version of the subtraction argument for metaphysical nihilism, the view that there could have been no concrete objects at all. I argue that the two premises of their argument are only jointly acceptable if the quantifiers in one range over a different set of objects from those which the quantifiers in the other range over, in which case the argument is invalid. So either the argument is invalid or we should not accept (...) both its premises. (shrink)

It is clear throughout Cognitive Gadgets Heyes believes the development of cognitive capacities results from the interaction of genes and experience. However, she opposes cognitive instincts theorists to her own view that uniquely human capacities are cognitive gadgets. Instinct theorists believe that cognitive capacities are substantially produced by selection, with the environment playing a triggering role. Heyes’s position is that humans have similar general learning capacities to those present across taxa, and that sophisticated human cognition is substantially created by our (...) socioculturally transmitted environment. It is a core strategy of Heyes to provide evidence of learning altering a cognitive capacity to conclude that a capacity is a cognitive gadget and not an instinct. We draw on recent work on the evolution of learning preparedness to examine the adequacy of this strategy. In particular, we analyse experimental evolution work showing how selection affects cognition within the laboratory. First, this work reveals that change due to learning can still be retained under genetic assimilation. This suggests that domain-specific adaptation can coexist with learning, moderate nativism, an option missed by the instinct versus gadget distinction. Second, we describe the conditions that select for increased preparedness in learning: certainty, reliability, and particular costs. We consider how these conditions can be used when conducting evolutionary reasoning about cognition, applying them to the important capacity for imitation. We find that the conditions lend theoretical support to moderate nativism about the capacity to imitate, which is supported by psychological evidence. (shrink)

In 1856, the State of Ohio began an enumeration of its population to count and identify people with disabilities. This paper examines the ethical role of the accounting profession in this project, which supported the transatlantic eugenics movement and its genocidal attempts to eliminate disabled persons from the population. We use a theoretical approach based on Levinas who argued that the self is generated through engagement with the Other, and that this engagement presupposes a responsibility to and for the Other. (...) We show that successive waves of legislation relied on State and County auditors along with Township clerks and assessors to conduct the mechanics of the enumeration of the population, which focused on the identification, categorization, and counting of the disabled people of the State. We argue that the accounting-based technologies of enumeration and reporting objectify the enumerated persons and deny the auditor’s pre-existing ethical obligation to this new Other. We show how the financial expertise and structures of the State were engaged in the execution of this mandate, which remained in place for over a century and supported a program of institutionalization. We consider the ramifications of this for our understanding of the ethical role of public sector accounting in the United States over this period, which has been under-explored. (shrink)

This paper aims to settle the question of what Ludwig Wittgenstein meant by "what solipsism means": This remark provides the key to the problem, how much truth there is in solipsism. For what solipsism means is quite correct; only it cannot be said, but makes itself manifest. The world is my world: this is manifest in the fact that the limits of language mean the limits of my world. 1 Throughout this paper, I will paraphrase "what solipsism means" simply as (...) 'solipsism.'2 The aim of the present paper can then be restated as an attempt to specify the conception of solipsism Wittgenstein was addressing in the Tractatus Logico-Philosophicus.

The so-called March of Progress depicts human evolution as a linear progression from mohkey to man. Shelley (1996) analyzed this image as a visual argument proceeding through "rhetorical" and "demonstrative" modes of visual logic. In this paper, I confirm and extend this view of visual logic by examining variations of the original March image. These variations show that each mode of visual logic can be altered or isolated in support of new conclusions. Furthermore, the March can be included in a (...) visual "frame" to produce new arguments, much as a verbal argument can be made a component of a new and larger argument. (shrink)

Whether there is a general moral obligation to obey the law, often referred to as ‘political obligation’, is an enduring question in contemporary legal and political philosophy. Theories are continually being formulated, criticized, and reformulated as theorists attempt to settle this issue. However, there yet remains no general consensus as to whether any theory successfully answers this question in either the affirmative or the negative. I propose the legal doctrine of quasi-contract as a candidate for making sense of this persistent (...) issue. While the duty to reciprocate and the principle of reasonable expectations each falls short when independently advanced as a theory of political obligation, quasi-contract, which combines reciprocity, reasonable expectations, and additional moral considerations, is able to establish a satisfactory account of political obligation.

For A. J. Ayer, the occurrence of delusions confutes the notion that we perceive the world directly. He argues instead that perceptions are caused by immaterial “sense data” which somehow represent the properties of material things to us in our experiences. J. L. Austin systematically rejects Ayer’s claims, arguing that the occurrence of delusions does not preclude the possibility of direct perception, and that, indeed, our normal perception is direct. I challenge both philosophers’ ideas by examining how they deal with (...) the phenomenon of colour. (shrink)

The World is Born From Zero is an investigation into the relationship between video games and science fiction through the philosophy of speculation. Cameron Kunzelman argues that the video game medium is centered on the evaluation and production of possible futures by following video game studies, media philosophy, and science fiction studies to their furthest reaches. Claiming that the best way to understand games is through rigorous formal analysis of their aesthetic strategies and the cultural context those strategies emerge (...) from, Kunzelman investigates a diverse array of games like The Last of Us, VA-11 Hall-A, and Civilization VI in order to explore what science fiction video games can tell us about their genres, their ways of speculating, and how the medium of the video game does (or does not) direct us down experiential pathways that are both oppressive and liberatory. Taking a multidisciplinary look at these games, The World is Born From Zero offers a unique theorization of science fiction games that provides both science fiction studies and video game studies with new tools for thinking how this medium and mode inform each other.

BackgroundResponsive neurostimulation has been utilized as a treatment for intractable epilepsy. The RNS System delivers stimulation in response to detected abnormal activity, via leads covering the seizure foci, in response to detections of predefined epileptiform activity with the goal of decreasing seizure frequency and severity. While thalamic leads are often implanted in combination with cortical strip leads, implantation and stimulation with bilateral thalamic leads alone is less common, and the ability to detect electrographic seizures using RNS System thalamic leads is (...) uncertain.ObjectiveThe present study retrospectively evaluated fourteen patients with RNS System depth leads implanted in the thalamus, with or without concomitant implantation of cortical strip leads, to determine the ability to detect electrographic seizures in the thalamus. Detailed patient presentations and lead trajectories were reviewed alongside electroencephalographic analyses.ResultsAnterior nucleus thalamic leads, whether bilateral or unilateral and combined with a cortical strip lead, successfully detected and terminated epileptiform activity, as demonstrated by Cases 2 and 3. Similarly, bilateral centromedian thalamic leads or a combination of one centromedian thalamic alongside a cortical strip lead also demonstrated the ability to detect electrographic seizures as seen in Cases 6 and 9. Bilateral pulvinar leads likewise produced reliable seizure detection in Patient 14. Detections of electrographic seizures in thalamic nuclei did not appear to be affected by whether the patient was pediatric or adult at the time of RNS System implantation. Sole thalamic leads paralleled the combination of thalamic and cortical strip leads in terms of preventing the propagation of electrographic seizures.ConclusionThalamic nuclei present a promising target for detection and stimulation via the RNS System for seizures with multifocal or generalized onsets. These areas provide a modifiable, reversible therapeutic option for patients who are not candidates for surgical resection or ablation. (shrink)

Is there a distinctively epistemic kind of blame? It has become commonplace for epistemologists to talk about epistemic blame, and to rely on this notion for theoretical purposes. But not everyone is convinced. Some of the most compelling reasons for skepticism about epistemic blame focus on disanologies, or asymmetries, between the moral and epistemic domains. In this paper, I defend the idea that there is a distinctively epistemic kind of blame. I do so primarily by developing an account of the (...) nature of epistemic blame. My account draws on a prominent line of theorizing in moral philosophy that ties blame to our relationships with one another. I argue that with my account of epistemic blame on hand, the most compelling worries about epistemic blame can be deflated. There is a distinctively epistemic kind of blame. (shrink)

Prosopography is the collection of all known information about individuals within a given period. With the advent of computer technology it is now possible to gather and store such information in increasingly sophisticated and searchable databases, which can bring a new dimension to traditional historical research. The book surveys the transition in prosopographical research from more traditional methods to the new technology, and discusses the central role of the British Academy, as well as that of French, German and Austrian academic (...) institutions, in developing prosopographical research on the Later Roman Empire, Byzantium and now Anglo-Saxon and other periods. The book demonstrates mutual benefits and complementarity in such studies between the use of new technology and the highest standards of traditional scholarship, and in doing so it sets forth new perspectives and methodologies for future work.

This article revolves around the debate surrounding the lack of a coherent definition for corporate social responsibility (CSR). I make use of Jacques Derrida’s theorizing on contested meaning to argue that CSR’s ambiguity is actually necessary in light of its functional role as a “supplement” to corporate profit-seeking. As a discourse that refuses to conclusively resolve the tension between profit-seeking and prosociality, CSR expresses an important critical perspective which demands that firms act responsibly, while retaining the overall corporate frame of (...) shareholder supremacy. CSR does this by ambivalently affirming both profit-seeking and prosociality, a necessary contradiction. Attempts to reduce CSR’s ambiguity can thus only succeed by undermining its viability as a normative discourse that captures how certain elements of society understand how firms should act. The analysis suggests that greater scholarly attention is needed with regard to the material discursive environments within which discourses such as CSR are deployed. A discursive approach to research could thus benefit future practitioners, who have to act according to fluid standards of responsibility that cannot be authoritatively defined, but which can be better understood than they are at present.

But the nature of visual mental imagery and its participation in abductive inference is not systematically understood.

This work supports the conclusion that visual abduction is useful to scientists under certain conditions and that (...) it is amenable to detailed study. (shrink)

This paper provides a critical overview of recent work on epistemic blame. The paper identifies key features of the concept of epistemic blame and discusses two ways of motivating the importance of this concept.

In addition to providing an overview of the state of the art of this growing but controversial field, the paper highlights (...) areas where future work is needed. (shrink)

There is a high prevalence of comorbidity between neurodevelopmental disorders. Contemporary research of these comorbidities has led to the development of multifactorial theories of causation, including the multiple deficit model. While several combinations of disorders have been investigated, the nature of association between literacy and motor disorders remains poorly understood. Comorbid literacy and motor disorders were the focus of the two present studies. In Study 1, we examined the prevalence of comorbid literacy and motor difficulties relative to isolated literacy and (...) motor difficulties in a community sample. The prevalence of comorbidity was five times greater than expected by chance alone, implying some relationship between difficulties. In Study 2, we examined the cognitive profiles of children with literacy and motor disorders amongst a subsample of children from Study 1. Children with literacy disorder had deficits in phonological processing, selective attention, and memory whilst children with motor disorder had deficits in visuospatial processing and memory, suggesting the disorders should be considered to have both independent and shared cognitive risk factors. Children with comorbid literacy and motor disorder demonstrated an additive combination of these deficits. Together, these findings are consistent with predictions from the MDM. (shrink)

We see unique opportunities to advance emotional research by studying an overlooked environmental problem. The biodiversity crisis is caused by land use, in particular by reducing and damaging habitats, such as deforestation for cattle grazing. Biodiversity processes are proximate and personally moving, like when a person is causing or experiencing changes to livelihood-providing ecosystems, and we suggest this affect-rich context is useful for studying social and psychological processes. In contrast, much research on far-away populations thinking about climate change effects involves (...) more abstract and distant cognitions. We also suggest biodiversity-related emotions have consequential outcomes for health and behavior, and provide advice for shaping research programs on specific populations and wildlife interactions.

One challenge in developing an account of the nature of epistemic blame is to explain what differentiates epistemic blame from mere negative epistemic evaluation. The challenge is to explain the difference, without invoking practices or behaviors that seem out of place in the epistemic domain. In this paper, I examine whether the most sophisticated recent account of the nature of epistemic blame—due to Jessica Brown—is up for the challenge. I argue that the account ultimately falls short, but does so in (...) an instructive way. Drawing on the lessons learned, I put forward an alternative approach to the nature of epistemic blame. My account understands epistemic blame in terms of modifications to the intentions and expectations that comprise our “epistemic relationships” with one another. This approach has a number of attractions shared by Brown’s account, but it can also explain the significance of epistemic blame. (shrink)

In De Anima 2.4, Aristotle claims that nutritive soul encompasses two distinct biological functions: nutrition and reproduction. We challenge a pervasive interpretation which posits ‘nutrients’ as the correlative object of the nutritive capacity. Instead, the shared object of nutrition and reproduction is that which is nourished and reproduced: the ensouled body, qua ensouled. Both functions aim at preserving this object, and thus at preserving the form, life, and being of the individual organism. In each case, we show how Aristotle’s detailed (...) biological analysis supports this ontological argument. (shrink)

The following annotated bibliography contains a reasonably complete survey of contemporary work in the philosophy of astrophysics. Spanning approximately 40 years from the early 1980s to the present day, the bibliography should help researchers entering the field to acquaint themselves with its major texts, while providing an opportunity for philosophers already working on astrophysics to expand their knowledge base and engage with unfamiliar material.

The logical empiricists held that an analogical hypothesis does not gain any acceptability from the analogy on which it is founded. On this view, the acceptability of a hypothesis cannot be discounted by criticizing the foundational analogy. Yet scientists commonly appear to level exactly this sort of criticism. If scientists are able to discount the acceptability of analogical hypotheses in this way, then the logical empiricist view is mistaken. I analyze four forms of analogy counterargument, disanalogy, misanalogy, counteranalogy, and false (...) analogy, with examples from the debate over the asteroid impact hypothesis. These counterarguments do address the acceptability of analogical hypotheses, indicating that analogies can confer acceptability, confirmation notwithstanding. 1 Introduction 2 The asteroid impact hypothesis 3 Analogy counterarguments 3.1 Disanalogy 3.2 Misanalogy 3.3 Counteranalogy 3.4 False analogy 4 Acceptability 5 Conclusions.

It has been known for over a century that there is an afferent, as well as an efferent, component to the visceral-atonomic nervous system. Despite the fundamental importance of bodily afferent information- sometimes called interoception- to central nervous system control of visceral organ function, emotional-motivational processes, and dysfunction of these processes, including psychosomatic disorders, its role did not receive much attention until quite recently. This is the first comprehensive review of this topic and it covers both neurobiological and psychobiological aspects. (...) The author first defines the issue and gives an historical background starting with the James-Lange theory of emotion, and addresses learning and motivation, roots in Pavlovian conditioning research, and operant conditioning of visceral function. In the second section he reviews recent scientific findings in the neural basis of visceral perception and studies in cardiovascular-respiratory and alimentary interoception. Finally, he discusses several related areas of research and theory including drug state issues, interoception and psychiatric disorders, and bodily consciousness, and suggests directions for future investigation. The book will be of interest to scientists in neurobiology, psychology, and brain imaging, to indivuals in related clinical fields such as psychiatry, neurology, cardiology, gastroenterology, and clinical psychology, and to their students and trainees.

BackgroundInaccurate citations are erroneous quotations or instances of paraphrasing of previously published material that mislead readers about the claims of the cited source. They are often unaddressed due to underreporting, the inability of peer reviewers and editors to detect them, and editors’ reluctance to publish corrections about them. In this paper, we propose a new tool that could be used to tackle their circulation.MethodsWe provide a review of available data about inaccurate citations and analytically explore current ways of reporting and (...) dealing with these inaccuracies. Consequently, we make a distinction between publication and circulation of inaccurate citations. Sloppy reading of published items, literature ambiguity and insufficient quality control in the editorial process are identified as factors that contribute to the publication of inaccurate citations. However, reiteration or copy-pasting without checking the validity of citations, paralleled with lack of resources/motivation to report/correct inaccurate citations contribute to their circulation.Results and discussionWe propose the development of an online annotation tool called “MyCites” as means with which to mark and map inaccurate citations. This tool allows ORCID users to annotate citations and alert authors and also editors of journals where inaccurate citations are published. Each marked citation would travel with the digital version of the document and be visible on websites that host peer-reviewed articles. In the future development of MyCites, challenges such as the conditions of correct/incorrect-ness and parties that should adjudicate that, and, the issue of dealing with incorrect reports need to be addressed.

I respond to Tim Smartt’s (2023) skepticism about epistemic blame. Smartt’s skepticism is based on the claims that (i) mere negative epistemic evaluation can better explain everything proponents of epistemic blame say we need epistemic blame to explain; and (ii) no existing account of epistemic blame provides a plausible account of the putative force that any response deserving the label “blame” ought to have. He focuses primarily on the prominent “relationship-based” account of epistemic blame to defend these claims, arguing that (...) the account is explanatorily idle, and cannot distinguish between epistemically excused and epistemically blameworthy agents. I argue that Smartt mischaracterizes the account’s role for judgments of epistemic relationship impairment, leading to mistaken claims about the account’s predictions. I also argue that the very feature of the account that Smartt mischaracterizes is key to understanding what epistemic blame does for our epistemic responsibility practices that mere negative epistemic evaluation cannot.

Orality, generally defined as the preference for the spoken over the written word, is an academic discipline that has only recently received attention from the missiological community. The reality of widespread oral preference, also known as “secondary orality,” is no less true in Europe. In this article, the author focuses on the Romanian context. Using qualitative research gleaned from interviews with nine university-educated Romanians, patterns are developed that display how “secondary oral learners” choose to learn and retain new information. Specific (...) attention is given to theologically-related material. Six implications for theological education are advanced in the areas of (1) hermeneutics, (2) preaching, (3) evangelism, (4) discipleship, (5) church planting, and (6) leadership development. Paths forward for ministry in oral preference cultures like Romania are developed. The author concludes that the implementation of such suggestions could lead to more holistic ministry and is potentially transferrable to similar contexts. (shrink)
