RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

NUTRIÇÃO SOBRE A AZOOSPERMIA EM BOVINOS -/- -/- E. I. C. da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim Departamento de Zootecnia – UFRPE sede -/- AZOOSPERMIA EM BOVINOS -/- INTRODUÇÃO -/- A falta completa de esperma no ejaculado pode ser devido a uma falha no processo de espermatogênese ou relacionada a causas no transporte do esperma. Com relação ao transporte, o esperma pode ser impedido de ser ejaculado mediante bloqueios ou oclusões no sistema do ducto extragonadal, ou (...) por causa de uma disfunção ejaculatória. Nos cães, por exemplo, a possibilidade de oclusão ser a causa pode ser determinada por medições de fosfatase alcalina (ALP) no plasma seminal, já que a ALP se origina do epidídimo e seminífero epitélio tubular. Se a concentração de ALP no fluido seminal for superior a 5000 UI/l, a amostra ejaculada contém fluido desses tecidos e a oclusão pode ser descartada. -/- As causas testiculares da azoospermia incluem a falha da espermatogênese, que pode ser causada por uma série de fatores; estes incluem fatores hormonais, imunológicos, congênitos, tóxicos, patogênicos, traumáticos e nutricionais. Aqui, as supressões na região do AZF (que contém sub-regiões AZFa, AZFb e AZFc) no cromossoma Y desempenham um papel importante, representando 10-15% dos casos de azoo- e oligospermia. Na região AFZc, o gene DAZ, que é suprimido na azoospermia, é considerado importante no controle espermatogênico, uma vez que a sua eliminação é frequentemente detectada em homens e/ou animais inférteis. -/- A perda total da capacidade de formação de espermatozoides pelo epitélio testicular e, portanto, a ausência de espermatozoides viáveis ou não no volume ejaculado pelo animal é denominado como azoospermia (VARNER et al., 2000), um macho nessas condições deve ser imediatamente retirado dos processos produtivos e não é, de forma alguma, viável para fins reprodutivos. A origem da causa pode ter caráter nutricional, ou outras, sendo multifatoriais; em processos crônicos severos pode-se chegar à azoospermia reversível, que é diagnosticada e corrigida de forma oportuna. Entre os principais fatores de caráter nutricional temos: -/- 18.1 Nitratos (NO3-) e nitritos (NO2-) -/- Quando os ruminantes consomem uma alimentação com elevadas concentrações de nitratos (presente principalmente nas forrageiras) parte do nitrato não pode ser imediatamente convertido em nitrito e, por fim, em amoníaco (todas essas transformações acontecem no rúmen mediante a flora microbiana); isso faz com que nitrato e nitrito se acumulem no rúmen. A adição do nitrato no rúmen intensifica o problema. O envenenamento por nitrato ocorre quando o nível de nitrito presente no rúmen excede a capacidade do microbiota para convertê-lo em amoníaco. Quando isto acontece, o nitrato e o nitrito são absorvidos através da parede do rúmen e entram na circulação sanguínea. É o nitrito que causa a toxicidade. -/- Estudou-se o equilíbrio ácido-básico e sua relação com a reprodução e produção, postulando a hipótese de que esse equilíbrio afeta os mecanismos endócrinos e metabólicos, além dos reprodutivos. -/- 18.2 Relação energia:proteína -/- Quando a alimentação apresenta deficiências de energia aumenta-se a degradação das gorduras (provenientes do tecido adiposo), acompanhada pela redução da liberação de insulina (hipoinsulinemia) afetando-se a lipogênese, mobilizando-se mais gordura corporal do que se sintetiza. -/- Situações como a acidose ruminal (excesso de grão e deficiência em fibras) ou alcalose ruminal (excesso de ureia com baixa energia digerível) resultam em perturbações sobre a fertilidade; além disso, deficiências energéticas graves que levam à cetose causam estresse com a liberação de catecolaminas, ACTH e TSH que afetam a secreção de GnRH, afetando por fim, a espermiogênese. -/- -/- Uma diminuição de energia na alimentação gera hipoglicemia que, ao mesmo tempo, produz hipoinsulinemia incrementando assim a lipólise em tecidos, gerando como produtos as cetonas. -/- A hipoinsulinemia juntamente com a cetonemia e a geração de beta-endorfinas, por problemas na alimentação, reduzem notavelmente a síntese de GnRH. A GnRH reduz a liberação do LH e FSH. A diminuição da liberação do LH provoca azoospermia hipogonadotrópica com efeitos de estimulação hormonal anormais segundo a avaliação endócrina, bem como a obstrução testicular inexplicada. -/- Se houver um aumento significativo na liberação de FSH, a azoospermia hipogonadotrópica é refletida em diagnóstico como disfunção testicular. -/- 18.3 Minerais (Selênio Se) -/- Quando os níveis de Se na dieta são deficientes, ocorrem falhas na formação e maturação espermática. O Se mostra uma grande influência na fertilidade do macho afetando a qualidade do sêmen, o plasma seminal contém elevadas quantidades de GSH-Px, cuja função é proteger a membrana do espermatozoide do ataque peroxidativo; além disso, na cauda do gameta masculino há um selenopeptídeo que faz com que, em uma deficiência de Se, produza-se uma fratura no meio da cauda do espermatozoide. -/- O esperma dos animais com deficiência de Se apresentam pobre motilidade com características de desenvolvimento anormal na cauda do esperma. Demonstrou-se que a deficiência de Se, não somente precipita o problema em reprodutores, mas que o esperma deformado, foi menos efetivo na subsequente fertilização do ovócito ovulado (HAWKES et al., 2001), ou seja, animais que possuem deficiência desse mineral podem ter esperma inapropriado para a destinação de inseminação artificial ou mesmo a monta natural, uma vez que a taxa de concepção estará bastante baixa. -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- BARRENHO, Gonçalo José Pinheiro.

This study evaluates the relationship between mental health and academic motivation among third-year college TES grantees. Thus, correlational design was employed to determine if there is a significant relationship between mental health and academic motivation among 150 third-year TES grantees. Statistical findings reveal that the r coefficient of 0.52 indicates a moderate positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to rejecting the null hypothesis. Hence, a significant relationship exists between mental health and (...) academic motivation of third-year college TES grantees. Implications were discussed in the study. (shrink)

This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...) stereotypical inferences which are contextually inappropriate. We analyse a classical paradox about perception, suggest it relies on contextually inappropriate stereotypical inferences from appearance-verbs, and show that the conditions we identified as leading to contextually inappropriate stereotypical inferences are met in formulations of the paradox. Three experiments use a forced-choice plausibility-ranking task to document the predicted inappropriate inferences, in English, German, and Japanese. The cross-linguistic study allows us to assess the wider relevance of the proposed analysis. Our findings open up new perspectives for ‘evidential’ experimental philosophy. (shrink)

The existence of God is once again the focus of vivid philosophical discussion. From the point of view of analytic theology, however, people often talk past each other when they debate about the putative existence or nonexistence of God. In the worst case, for instance, atheists deny the existence of a God, which no theists ever claimed to exist. In order to avoid confusions like this we need to be clear about the function of the term 'God' in its different (...) contexts of use. In what follows, I distinguish between the functions of 'God' in philosophical contexts on the one hand and in theological contexts on the other in order to provide a schema, which helps to avoid confusion in the debate on the existence or non-existence of God.

Epistemologists have long believed that epistemic luck undermines propositional knowledge. Action theorists have long believed that agentive luck undermines intentional action. But is there a relationship between agentive luck and epistemic luck? While agentive luck and epistemic luck have been widely thought to be independent phenomena, we argue that agentive luck has an epistemic dimension. We present several thought experiments where epistemic luck seems to undermine both knowledge-how and intentional action and we report experimental results that corroborate these judgments. These (...) findings have implications for the role of knowledge in a theory of intentional action and for debates about the nature of knowledge-how and the significance of knowledge representation in folk psychology.

New technologies are the source of uncertainties about the applicability of moral and morally connotated concepts. These uncertainties sometimes call for conceptual engineering, but it is not often recognized when this is the case. We take this to be a missed opportunity, as a recognition that different researchers are working on the same kind of project can help solve methodological questions that one is likely to encounter. In this paper, we present three case studies where philosophers of technology implicitly engage (...) in conceptual engineering (without naming it as such). We subsequently reflect on the case studies to find out how these illustrate conceptual engineering as an appropriate method to deal with pressing concerns in the philosophy of technology. We have two main goals. We first want to contribute to the literature on conceptual engineering by presenting concrete examples of conceptual engineering in the philosophy of technology. This is especially relevant, because the technologies that are designed based on the conceptual work done by philosophers of technology potentially have crucial moral and social implications. Secondly, we want to make explicit what choices are made when doing this conceptual work. Making explicit that some of the implicit assumptions are, in fact, debated in the literature allows for reflection on these questions. Ultimately, our hope is that conscious reflection leads to an improvement of the conceptual work done. (shrink)

The role of certitude in our mental lives is, to put it mildly, controversial. Many current epistemologists (including epistemologists of religion) eschew certitude altogether. Given his emphasis on certitude, some have maintained that John Henry Newman was an infallibilist about knowledge. In this paper, we argue that a careful examination of his thought (especially as seen in the Grammar of Assent) reveals that he was an epistemic fallibilist. We first clarify what we mean by fallibilism and infallibilism. Second, we explain (...) why some have read Newman as an infallibilist. Third, we offer two arguments that Newman is at least a fallibilist in a weak sense. In particular, the paradox he seeks to resolve in the Grammar and his dispute with John Locke both indicate that he is at least a weak fallibilist. We close with a consideration of whether Newman is a fallibilist in a much stronger sense as well. (shrink)

A discussion of several tensions between Thomistic philosophy and modern Darwinian theory as well as several recent Thomistic criticisms of intelligent design.

These comments, which take the form of criticism and response, were the basis of a zoom conversation at the Eastern APA, January 2021. Josh is putting them up on philpapers (with permission from all involved) in case they are helpful to people interested in the themes of this book.

Abstract: In this article we introduce an input-oriented democratic innovation – that we term ‘TaxTrack’ – which offers individual taxpayers the means to engage with their political economies in three ways. After joining the TaxTrack program, an individual can: (1) see and understand how much, and what types, of taxes they have contributed, (2) see and understand how their tax contributions are, or have been, used, and (3) control what their tax contributions can, or cannot, be spent on. We explain (...) this democratic innovation in two ways. The first is through evocation to prefigure what the innovation could look like in future practise which raises the prospects for both good and problematic outcomes. The second is through formal theory to produce a detailed model of the innovation to assist theory building. We conclude by discussing three interactive outcomes of ‘TaxTrack’ through the democratic innovations literature to establish the beginnings of a theory for the model. This theory tells us that ‘TaxTrack’ can return benefits to its users and the democratic regimes in which they are located but it may also place restrictions on output-oriented innovations like Participatory Budgeting.

Karl Christian Friedrich Krause left an impressive oeuvre consisting of 256 books and articles, covering numerous branches of philosophy, the humanities, and science.[1] His Urbild der Menschheit, his Vorlesungen über das System der Philosophie and his Vorlesungen über die Grundwahrheiten der Wissenschaft are of particular pertinence for philosophers today.

Contextualism (the view that ‘knowledge’ and its variants are context-sensitive) has been supported in large part through appeal to intuitions about Keith DeRose’s Bank Cases. Recently, however, the contextualist construal of these cases has come under fire from Kent Bach and Jennifer Nagel who question whether the Bank Case subject’s confidence can remain constant in both low- and high-stakes cases. Having explained the Bank Cases and this challenge to them, I argue that DeRose has given a reasonable reply to this (...) initial challenge. However, I proceed to argue that the current stalemate can be broken. Seeking to extend the Bach-Nagel critique, I offer a novel interpretation of the Bank Cases according to which the subject’s evidence changes between low- and high-stakes cases. If I am correct, then, given the amount of support the Bank Cases have been thought to lend contextualism, the case for contextualism is seriously weakened. (shrink)

In this chapter, Gage and McAllister respond to various objections to the phenomenal conservative position in religious epistemology. In particular, they respond to the objections that seemings are the ultimate source of justification, that PC makes epistemic justification too easy, that PC involves conceptual circularity, and that PC lacks an objective connection to truth.

The report describes an application of ontologies to the analysis of wind turbine manufacturing data. We show how applying ontologies to composite materials data may facilitate the discovery of optimum composite material designs that will deliver maximum wind turbine blade performance within environmental constraints.

A brief introduction to the life and key work of Rudolf Carnap with special attention to his work on inductive logic.

An important question about moral progress is what causes it. One of the most popular proposed mechanisms is moral reasoning: moral progress often happens because lots of people reason their way to improved moral beliefs. Authors who defend moral reasoning as a cause of moral progress have relied on two broad lines of argument: the general and the specific line. The general line presents evidence that moral reasoning is in general a powerful mechanism of moral belief change, while the specific (...) line tries to establish that moral reasoning can explain specific historical examples of moral progress. In this paper, we examine these lines in detail, using Kumar and Campbell’s (2022, A Better Ape: The Evolution of the Moral Mind and How It Made Us Human. Oxford University Press) model of rational moral progress to sharpen our focus. For each line, we explain the empirical assumptions it makes; we then argue that the available evidence supports none of these assumptions. We conclude that at this point, we have no idea if moral reasoning causes moral progress. (shrink)

Dans ce qui suit, je m'attache à présenter les éléments d'une doctrine philosophique, qui peut être définie comme un contextualisme dialectique. Je m'efforce tout d'abord de définir les éléments constitutifs de cette doctrine, à travers les dualités et pôles duaux, le principe d'indifférence dialectique et le biais d'uni-polarisation. Je m'attache ensuite à souligner l'intérêt spécifique de cette doctrine au sein d'un domaine particulier de la méta-philosophie : la méthodologie utilisée pour la résolution des paradoxes philosophiques. Je décris enfin une application (...) de cette dernière aux paradoxes suivants : le paradoxe de Hempel, le paradoxe de l'examen-surprise et l'argument de l'Apocalypse. (shrink)

Proponents of public reason views hold that the exercise of political power ought to be acceptable to all reasonable citizens. This article elucidates the common structure shared by all public reason views, first by identifying a set of questions that all such views must answer and, second, by showing that the answers to these questions stand in a particular relationship to each other. In particular, we show that what we call the ‘rationale question’ is fundamental. This fact, and the common (...) structure more generally, are often overlooked or distorted within the literature. As a result, we argue, several prominent argumentative moves made by both critics and defenders of public reason are unsuccessful. Our overall conclusion is that discussions of public reason views would be more fruitful if they made consistent use of the common structure we identify. (shrink)

Public shaming plays an important role in upholding valuable social norms. But, under what conditions, if any, is it morally justifiable? Our aim in this paper is systemically to investigate the morality of public shaming, so as to provide an answer to this neglected question. We develop an overarching framework for assessing the justifiability of this practice, which shows that, while shaming can sometimes be morally justifiable, it very often is not. In turn, our framework highlights several reasons to be (...) concerned about the increasingly widespread phenomenon of online public shaming. (shrink)

If the sun were to suddenly go out we wouldn't know it for 8 minutes. But if Alice is sitting in the middle of the sun and measures one of a pair of entangled particles and we measure the other one, what direction she measures her particle in has instantaneous effects on the one we measure. This is resolved in the Presentist Fragmentalist interpretation of QM.

We are witnessing increasing use of the Internet, particular social media, to criticize (perceived or actual) moral failings and misdemeanors. This phenomenon of so-called ‘online public shaming’ could provide a powerful tool for reinforcing valuable social norms. But it also threatens unwarranted and severe punishments meted out by online mobs. This paper analyses the dangers associated with the informal enforcement of norms, drawing on Locke, but also highlights its promise, drawing on recent discussions of social norms. We then consider two (...) crucial conditions that online public shaming must meet in order to be justifiable: proportionality and accountability. We argue that these requirements are in fact frequently violated, rendering most cases of online public shaming unjustified. While the use of online public shaming against others’ vices has some apparent virtues, it is currently rarely justified, given its own vices. (shrink)

In a Covid-19 world, everyone’s circumstances changed. Most of us are living and or working in quarantine or lockdown. There is evidence that lockdown itself can have serious negative psychological impact (Brooks et al., 2020). Nonetheless, strategies are being proposed which, arguably, mitigate these harms. Artmaking is one such strategy. As ‘art therapy’, it has been usefully deployed to address a wide range of mental health challenges including anxiety, depression, fatigue and post-traumatic stress (Regev & Cohen-Yatziv, 2018). Given that these (...) self-same impacts profile the mental health challenges identified in relation to pandemic isolation, art may be useful in mitigating mental health issues associated with lockdown. This paper does not address how the role art can play in the therapeutic mix for serious mental health disorders. More specifically it is focused on a narrower brief of ills – predominantly those associated with boredom and a loss of stimulation associated with the constrained circumstances of lockdown. The kind of ‘art therapy’ this paper has in mind is more accurately described as ‘art engagement’ as it concerns individuals actively engaging with art. Art engagement is taken as self-administered utilising the time-out imposed by lockdown as an opportunity to take stock and reset. I will argue that to be of optimal benefit to people in lockdown, the art engagement model should support art practices that are easily accessible to a wide range of people, and be broadly scoped regarding areas to explore. Finally, because the benefits flowing from art engagement are central to this quest, our art engagement model will need to be able to track how art enriches or impoverishes its practitioners. This paper will set up a framework for art engagement that provides an apt account of art practices suited to people in lockdown. I will examine how the resolution of two art puzzles point the way forward in developing an art engagement model. Adventitiously, understanding these puzzles will also prove useful for art making in constrained living arrangements. Managing the first of these puzzles requires a rejection of the notion that art can be determinately defined. Instead we opt for a model that privileges practices and products that enrich the lives of practitioners. The second puzzle assumes creativity relies to varying degrees on appropriation and so appropriation acts need to be included in the model. However, this comes at a cost. Appropriation disrupts any notion that art works are stable things situated forever in the realm of art. It will be shown that appropriation causes us to adopt a more expansive view about the fluidity of what counts as an artwork. This fluidity may take us into and out of the realm of what is traditionally thought of as ‘art’ entirely and leads us to abandon any dependency on art masters and art institutions in our artmaking quests. The paper will conclude by using the model described to outline three art engagement examples that demonstrate how sometimes ordinary everyday experiences can be enriched by taking an art-engaging stance even in the highly constrained environment of lockdown.

What was René Girard’s attitude towards philosophy? What philosophers influenced him? What stance did he take in the philosophical debates of his time? What are the philosophical questions raised by René Girard’s anthropology? In this interview, Paul Dumouchel sheds light on these issues.

We discuss Kant’s conception of beneficence against the background of the overdemandingness debate. We argue that Kant’s conception of beneficence constitutes a sweet spot between overdemandingess and undemandingess. To this end we defend four key claims that together constitute a novel interpretation of Kant’s account of beneficence: 1) for the same reason that we are obligated to be beneficent to others we are permitted to be beneficent to ourselves; 2) we can prioritise our own ends; 3) it is more virtuous (...) to do more rather than less when it comes to helping others; and 4) indifference to others is vicious. Finally, we explain how this represents a system of duties that gives our personal ends a moral standing without unacceptably moralising them. (shrink)

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in degrees. (...) Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

Creativity pervades human life. It is the mark of individuality, the vehicle of self-expression, and the engine of progress in every human endeavor. It also raises a wealth of neglected and yet evocative philosophical questions: What is the role of consciousness in the creative process? How does the audience for a work for art influence its creation? How can creativity emerge through childhood pretending? Do great works of literature give us insight into human nature? Can a computer program really be (...) creative? How do we define creativity in the first place? Is it a virtue? What is the difference between creativity in science and art? Can creativity be taught? The new essays that comprise The Philosophy of Creativity take up these and other key questions and, in doing so, illustrate the value of interdisciplinary exchange. Written by leading philosophers and psychologists involved in studying creativity, the essays integrate philosophical insights with empirical research. CONTENTS I.

Temporal discounting is a technical operation in climate change economics. When discount rates are positive, economic evaluation treats future benefits as less important than equivalent present benefits. This chapter explains and critically evaluates four different reasons economists have given for tying discount rates to the interest rates we observe in real-world markets. I suggest that while philosophers have correctly criticized three of these reasons, their criticisms of the fourth miss the mark. This is because philosophers have not taken heed of (...) the distinct analytical framework in which the fourth reason arises. (shrink)

Artificially intelligent (AI) technologies are increasingly being used in many workplaces. It is recognised that there are ethical dimensions to the ways in which organisations implement AI alongside, or substituting for, their human workforces. How will these technologically driven disruptions impact the employee–employer exchange? We provide one way to explore this question by drawing on scholarship linking Integrative Social Contracts Theory (ISCT) to the psychological contract (PC). Using ISCT, we show that the macrosocial contract’s ethical AI norms of beneficence, non-maleficence, (...) autonomy, justice, and explicability can feed into national- and organisational-level microsocial contracts. We also outline the role of employees’ technology frames in this process. We then use an illustrative example to demonstrate how this multilevel normative background helps to inform the content of individuals’ PCs in the context of working with AI technologies. (shrink)

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

This paper provides an examination of some problems caused by the concentration of influence in the capital markets of developed countries. In particular, I argue that large asset managers exercise quasi-political power that is not democratically legitimate. In section two, I will examine the economic driver behind the size and power of the big asset managers: the passive investing revolution. I will discuss several respects in which this revolution has fundamentally changed capital markets, most notably by making a large share (...) of investors universal owners. In the third section, I argue for my central analytical conjecture: asset managers exercise quasi-political power. They use their influence to shape the rules of the game in public capital markets in order to implement social and environmental policies that have traditionally been the exclusive purview of states. “Asset manager capitalism” is a recent term coined to refer to the contemporary system of corporate governance that succeeded the Berle and Means corporation with its dispersed ownership; the argument of this section is that asset manager capitalism is also a new political-economic regime. In the fourth section I defend my central normative claim: asset manager capitalism is an untenable and illegitimate political-economic arrangement, for at least two reasons. First, the power of asset managers is not checked by any institutional constraints, and is not rendered legitimate by any democratic process. More fundamental than this procedural critique is an argument that the interests of asset managers could not be aligned with the public interest, given the fact that the distribution of capital is highly unequal. I conclude by discussing several proposals to reform asset manager capitalism. (shrink)

My aim in this paper is to draw attention to a currently underdeveloped notion of pain and alienation, in order to sketch an account of the harms of ‘discursive abuse’. This form of abuse comprises systemic practices of violating a person’s vulnerable integrity as a knowing agent. Discursive abuse results in, what I would like to call, ‘agential alienation’. This particular genus of alienation, whose broad conceptual origins lie in the respective works of Hegel and the early Marx, involves an (...) agent being robbed of their self-conception as a rational inquirer and participant in a deliberative public sphere. Such alienation causes a particular kind of pain for an agent that often has harrowing material effects. (shrink)

Recasting Hume and Early Modern Philosophy is a collection of essays that are all concerned with major figures and topics in the early modern philosophy. Most of the essays are concerned, more specifically, with the philosophy of David Hume (1711-1776). The sixteen essays included in this collection are divided into five parts. These parts are arranged under the headings of: (1) Metaphysics and Epistemology; (2) Free Will and Moral Luck; (3) Ethics, Virtue and Optimism; (4) Skepticism, Religion and Atheism; and (...) (5) Irreligion and the Unity of Hume’s Thought. A particularly important theme running through many of these essays is the subject of Hume’s irreligious aims and intentions. The fifth and final part of the collection is devoted to an articulation and defence of this specific understanding of Hume’s philosophical thought. (shrink)

“Responsibility After ‘Morality’: Strawson’s Naturalism and Williams’ Genealogy” -/- Although P.F. Strawson and Bernard Williams have both made highly significant and influential contributions on the subject of moral responsibility they never directly engaged with the views of each other. On one natural reading their views are directly opposed. Strawson seeks to discredit scepticism about moral responsibility by means of naturalistic observations and arguments. Williams, by contrast, employs genealogical methods to support sceptical conclusions about moral responsibility (and blame). This way of (...) reading their views depends, however, on the assumption that the concept of responsibility that Strawson aims to defend is the same as Williams aims to discredit. The conception of responsibility that Williams aims to discredit is one that is based around the assumptions and aspirations of “the morality system”. This paper argues that while there is a plausible way of interpreting Strawson’s naturalism that uncouples it from the assumptions of “the morality system”, there remain significant differences between Strawson and Williams. More specifically, even if Strawson’s understanding of moral responsibility abandons the (narrow) assumptions of “morality”, Strawson is still committed to “conservative” and “optimistic” conclusions about moral responsibility that cannot be sustained.

.... The strategy I have defended involves drawing a distinction between those who can and cannot legitimately hold an agent responsible in circumstances when the agent is being covertly controlled (e.g. through implantation processes). What is intuitively unacceptable, I maintain, is that an agent should be held responsible or subject to reactive attitudes that come from another agent who is covertly controlling or manipulating him. This places some limits on who is entitled to take up the participant stance in relation (...) to agents who are rational self-controllers but nevertheless subject to covert control.26 In this way, what is compromised by conditions of covert control is not the responsibility of the agent as such. It is, rather, the participant stance of those other agents who covertly control him. Clearly it is possible to establish these specific limits on who can hold these agents responsible without denying that the agents themselves remain free and responsible. When we take this approach we will find that we are no longer faced with an unattractive choice between simply “biting the bullet” or having to “spit it out”. All we need to do is chew carefully, until there is nothing left that we find too hard to swallow. (shrink)

The present chapter discusses the implications of virtual reality for the theory and practice of embodied cognitive science. The chapter discusses how recent technological innovations are poised to reshape our understanding of the materially-embodied and environmentally-situated mind, providing us with a new means of studying the mechanisms responsible for intelligent behavior. The chapter also discusses how a synthetically-oriented shift in our approach to embodied intelligence alters our view of familiar problems, most notably the distinction between embedded and extended cognition. The (...) chapter concludes by challenging the idea that virtual worlds ought to be seen as nothing more than a scientific ‘sandpit’ for the study of the embodied mind. Some forms of embodied intelligence can, I suggest, exist solely in virtual reality. In this sense, the ‘Matrix’ is not just a means of testing ideas about the forms of embodied intelligence that inhabit our own physical reality; it is also a means of creating entirely new forms of embodied intelligence. It is by building virtual worlds that we open the door to a new reality—one that is home to a potentially infinite variety of embodied, embedded, and perhaps even extended beings. (shrink)

The market failures approach to business ethics has recently garnered substantial critical attention (see, e.g., Cohen and Peterson 2019; Moriarty 2020; Steinberg 2017; Hsieh 2017; von Kriegstein 2016; Smith 2018; Endorfer and Larue 2022; Singer 2018). Though precursors of this view can be found in the literature (e.g., McMahon 1981; Friedman 1970), it was Joseph Heath (2004, 2006, 2014, 2023) who developed the approach and gave it its name. The market failures approach (henceforth: MFA) is concerned with the ethical obligations (...) of managers of firms (Heath 2014, 69). Roughly, it holds that managers ought not to conduct their businesses in a way that exploits market failures. “Market failure” is a technical term, meaning any failure of the conditions of the first fundamental welfare theorem, sometimes called the “Pareto conditions” (see Arrow 1951). The theorem states that if the Pareto conditions hold, then the market equilibrium will use society’s scarce resources efficiently, meaning that no one could be made better-off without making anyone else worse off. Efficiency, according to Heath (2014, chapter 7), is the implicit morality of the market. We coordinate much of our shared activity using markets, Heath claims, because of their ability to produce efficient results. Markets are good forms of social organization, according to Heath, because they are the best way to promote our values given empirical facts about the frailties of human psychology and the informational constraints that we face. As such, managers ought not compromise the very conditions that justify a market economy by profiting from breakdowns in the market’s efficiency. Managers are permitted to maximize profits, so long as they do not violate the market’s norm of efficiency in so doing. This is because the fundamental justification for the profit motive is that it is necessary for the operation of the price system which is essential to the efficiency properties of markets. In this paper, I will argue that the MFA is more general than even Heath himself claims. The MFA describes the professional obligations of managers, but the view I develop, the generalized market failures approach, describes the obligations of all market participants. Since efficiency is the implicit morality of the market, it binds not just managers, but all market participants, including consumers, investors and workers. Market participants are permitted to maximize the benefit they gain from market interactions, as long as they do so in a way that does not take advantage of any market failures. Generalizing the MFA in this way has three benefits: first, we gain a unified understanding of the ethics of non-managerial market roles; second, we will develop an even better understanding of the duties of managers; finally, it gives us the resources to respond to some familiar objections to the MFA found in the literature. In the next section, I will further motivate the MFA and explain how this motivation can be easily generalized to other market roles. Importantly, one can avoid benefiting from a market failure in two distinct ways: by avoiding transactions that exploit market failures or by transacting in such markets and then remediating the harm done, by compensating those negatively affected by the market failure. This section concludes by discussing how the remediation duties are to be split between the transacting parties and how to identify the parties to whom compensation is owed. In section 3, I use the tools of the generalized MFA to develop a unified ethics of consumption, investment and labor, respectively. This is the basis of a grand abductive argument for the generalized MFA. The view is strongly supported by the fact that it provides attractive and unifying explanations of our obligations in domains as variegated as carbon offsetting, CEO compensation, the reparations white Americans owe to black Americans and occupational licensure. Section 4 briefly concludes. (shrink)

Iris Murdoch claims that “clear vision is a result of moral imagination and moral effort.” Our experience of the world can be blurred by egoism, inattentiveness, and other failings. I ask how we distinguish clear vision from distorted vision. Murdoch’s texts appeal to four factors: (A) attention; (B) unselfing; (C) a form of conceptual articulacy; and (D) love. I ask three questions about these standards: - Are these standards directed at the same goal? (For example, are they all geared toward (...) securing purely epistemic goals?) - Are these standards criterial for improvements in vision? (That is, does the presence of some combination of (A)-(D) constitute or guarantee better vision?) - Does Murdoch think that there’s a single best form of vision? (Such as the one attained by the person who manifests (A)-(D)?) In the secondary literature, the typical answers to these questions are: yes, yes, yes. But I give different answers: no, no, no.

Working beyond the inclination to inaugurate alternative theoretical traditions alongside canonical sociology, this article demonstrates the value of recovering latent gender theory from within classic concepts—in this case, Weber’s “charisma.” Close readings of Weber reveal, (a) tools for theorizing extraordinary, non-masculinist agency, and, (b) clues that account for the conventional wisdom (popular and scholastic) that charisma is “not for women.” While contemporary movements may be tempted to eschew charismatic leadership per se because of legacies of dominance by men, there is (...) value in Weber’s formulation, which anticipated the performative turn in social theory that would destabilize biologistic gender ontologies. Value in this exchange also flows back to Weber: by confronting his intermittent tendency to describe charisma in terms that we now recognize as “customs of manly power,” we reveal heretofore unseen imperfections (i.e., traditionalist modes of legitimation) in his ideal-type. This engagement thus demonstrates an empowering mutuality between contemporary gender theory and “the classics.” The article ends by theorising the nexus of gender and charisma in the case of Trump, pointing to possibilities for vitiating Donald Trump’s charisma, as well as for anti-Trumpian charisma.

This paper explores the implications of Zeynep Tufekci’s capacities approach to social movements, which explains the strength of social movements in terms of their capacities. Tufekci emphasises that the capacities of contemporary social movements largely depend upon their uses of new digital technologies, and of social media in particular. We show that Tufekci’s approach has important implications for the structure of social movements, whether and what obligations they can have, and for how these obligations distribute to their members. In exploring (...) these implications, we develop a tripartite taxonomy of social movements. Each type of social movement in the taxonomy corresponds to a different type of group: social campaigns, social struggles, and social agitations. We show that all three types of social movement can bear obligations in virtue of their capacities. Finally, we argue that a surprising upshot of the obligations of social movements is that members of oppressed groups can have obligations to resist their own oppression in virtue of being members of social movements.
