Responding to calls for more substantive studies into ethical and responsible lobbying, we analyze data collected over a 5-year period in Brussels to explore how individual lobbyists understand the ethical dimensions of their work. Mobilizing insights from the sociology of the professions, we expose an emerging lobbying professionalism and unpack practitioners’ understandings of what being a professional lobbyist entails, focusing in particular on their espoused values of transparency and honesty. While expectations to lobby more transparently and honestly stem from political (...) institutions, we find individual lobbyists—acting as conduits—attempt to disseminate these expectations by setting limits that incite their clients to embrace what policymakers consider professional lobbying practice. Our study contributes to corporate political activity (CPA) scholarship by providing a professions-based understanding of ethical and responsible approaches to lobbying. We provide new insights into contextual and individual-level factors behind the emergence of such approaches, and elucidate implications of lobbying professionalism for business and European Union (EU) governance.

Research over the last decades has stimulated a paradigm shift in biology from assuming fixed and dichotomous male and female sexual strategies to an appreciation of significant variation in sex and sexual behaviour both within and between species. This has resulted in the development of a broader biological understanding of sexual strategies, sexuality and variation in sexual behaviour. However, current introductory biological textbooks have not yet incorporated these new research findings. Our analysis of the content of current biology texts suggests (...) that in undergraduate biology curricula variation in sexual behaviour, sexual strategies and sexuality barely feature, even though sex is discussed in a range of contexts. In this aspect, biological teaching is lagging behind current research. Here, we draw attention to new findings in the biology of sex, and suggest how these might be incorporated in undergraduate teaching to provide a more contemporary and inclusive education for biology students.

Philosophical attention to animals can be found in a wide range of texts throughout the history of philosophy, including discussions of animal classification in Aristotle and Ibn Bâjja, of animal rationality in Porphyry, Chrysippus, Aquinas and Kant, of mental continuity and the nature of the mental in Dharmakīrti, Telesio, Conway, Descartes, Cavendish, and Voltaire, of animal self-consciousness in Ibn Sina, of understanding what others think and feel in Zhuangzi, of animal emotion in Śāntarakṣita and Bentham, and of human cultural uniqueness (...) in Xunzi. In recent years, there has been increased attention to animal minds in philosophical discussions across many areas of metaphysics, epistemology, and value theory. Given that nonhuman animals share some biological and psychological features with humans, and that we share community, land, and other resources, consideration of nonhuman animals has much to contribute to our philosophical activities. -/- Contemporary philosophy of animal minds often also engages with the sciences of animal cognition and behavior. The science of comparative cognition is a thriving area of research, complementing the philosophical study in two ways. For one, philosophers of animal cognition can use claims resulting from animal cognition studies as premises in philosophical discussions. For example, Jacob Beck (2012) relies on pigeons’ abilities to compare quantities to argue for nonconceptual content; Sidney Carls-Diamante (forthcoming) appeals to octopus behavior and physiology to defend embodied cognition; Richard Moore (2016a) refers to ape gestural communication to rethink the requirements for intentional communication; Andrew Barron and Colin Klein (2016) appeal to insect cognition research to defend new theories of consciousness; Sarah Vincent, Rebecca Ring, and Kristin Andrews (2019) cite dolphins’ social practices to argue for the existence of norms that do not require metacognition. -/- In addition, philosophers of animal cognition can examine the epistemology and methods used to justify the claims that arise from the science. Research into animal cognition has resulted in surprising claims about animal capacities, such as sociality in garter snakes (Skinner & Miller 2020), tool-use in ants (Maák et al. 2017), mirror self-recognition in fish (Kohda et al. 2019), empathy in rats (Bartal et al. 2011), social learning in fruit flies (Danchin et al. 2018), episodic memory in dogs (Fugazza et al. 2020), addition and subtraction in bees (Howard et al. 2019). How should we evaluate such claims? -/- Some philosophers have argued that animal cognition research is held to a higher standard than human cognition research, and that scientists working with animals are sometimes asked to solve skeptical problems (Halina 2015). Others have challenged scientific assumptions about the relationship between brain size and intelligence, as well as biases against invertebrates (Mikhalevich & Powell 2020). -/- Animal cognition research challenges philosophers to consider that many capacities and behaviors often assumed to require language, sophisticated technological capacities, or legal systems may in fact be had by other animals who lack these properties. In this way, animal cognition research often surprises us by showing that sophisticated-looking activity can be caused through rather simple mechanisms. -/- 1. What is Animal Cognition? 2.

Alasdair MacIntyre’s critique of managerial capitalism is well known, with some arguing that MacIntyrean thought is antithetical to contemporary capitalist business. Nevertheless, substantial efforts have been taken to demonstrate how different business activities constitute MacIntyrean practices, which points to an incoherence at the heart of MacIntyrean business ethics scholarship. This article proposes a way of bridging these perspectives, suggesting a reimagined MacIntyrean approach to business that is thoroughly ‘practice-led.’ A detailed comparison of accounting and management shows that while neither are (...) practices in ‘good order,’ they differ in significant ways: where management does not meet the criteria for a MacIntyrean practice, accounting is a ‘distorted’ practice. This leads to a categorisation of practice-led business activity, whereby the traditional tasks of management are subsumed, shared or subordinated to practices and practitioners. Insights on how this can be implemented are drawn from the ‘communities of practice’ literature and a consideration of professions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Deification through the Cross:Reflections from an Implied Ideal WorshiperAndrew J. SummersonKhaled Anatolios's most recent book, Deification through the Cross,1 develops a definition of salvation out of his experience of the Byzantine liturgy. This experience of worship offers an immersion in what he calls "doxological contrition." By this, Anatolios means that Christ saves us by offering us the ability to participate in the mutual glorification of the persons of the (...) Holy Trinity by vicariously repenting for our sins. For Anatolios, this objective content is subjectively appropriated in Byzantine Christian worship. To explore this theme, Anatolios develops a working account of "doxological contrition" through a synthetic discussion of the Lenten Triodion and Pentecostarion, books of liturgical hymnography that govern the Byzantine worship from Lent to Pentecost. Anatolios derives his approach from the adaption of reader response theory, which aims to expose the effect a text should have on the "implied ideal reader." As such, his account speaks from the perspective of the "implied ideal worshiper"—presumably a theologically educated congregant who can seize these themes that evaporate into the ether as quickly as incense swung throughout the church during the services.Let me say from the outset, I heartily recommend Anatolios's book. It is both an ambitious work and a rewarding read. Ambitious because Anatolios's approach makes otherwise fragmented theological disciplines—liturgical [End Page 1089] studies, Scripture, historical theology, and systematics—fruitful dialogue partners in his exposition of a working account of the Christian experience of salvation. Rewarding because the reader can explore in depth the touchstones of the Christian tradition through Anatolios's deep retrieval of a more coherent soteriology. Deification of the Cross demonstrates the perennial value of historical theology to correctly account for the "half-forgotten, half misunderstood" details of the Christian tradition in the face of caricatures that at best misrepresent and at worst present an idolatrous, counterfeit Christianity.Eastern Christian Liturgy and RevelationPerhaps I am not Anatolios's ideal audience; I may be too close to the source material and lack objectivity. That aside, the bulk of my reflections on this book comes from the perspective of an "implied ideal worshiper." I do share some of Anatolios starting points. Like Anatolios, I am a convert, scholar, and Eastern Catholic priest. Furthermore, I also share the discontent with which Anatolios begins his book, though perhaps for different reasons. He bemoans a loss of the experience of salvation. My own vocation as priest and scholar comes out of a frustrated wonder. As a college student, I set out to learn about this Church and its Tradition. I learned about the Sunday experience I was supposed be having. It was in university when I read for the first time John Paul II's 1995 apostolic letter Orientale Lumen, written to acquaint the wider Catholic Church with the riches of the Christian East. John Paul II dedicated much reflection to the "genius of Eastern liturgy," emphasizing its power to envelop all our human senses into the fullness of the mystery of God. It is worth quoting in full:Within this framework, liturgical prayer in the East shows a great aptitude for involving the human person in his or her totality: the mystery is sung in the loftiness of its content, but also in the warmth of the sentiments it awakens in the heart of redeemed humanity. In the sacred act, even bodiliness is summoned to praise, and beauty, which in the East is one of the best loved names expressing the divine harmony and the model of humanity transfigured, appears everywhere: in the shape of the church, in the sounds, in the colors, in the lights, in the scents. The lengthy duration of the celebrations, the repeated invocations, everything expresses gradual identification with the mystery celebrated with one's whole person. Thus the prayer of the Church already becomes participation in the heavenly liturgy, an anticipation of the final beatitude.(§11) [End Page 1090]The experience of this liturgy has been quite potent throughout history. It led to the baptism of the entire kingdom of Rus' in 988 AD. As the story goes, its ruler, Vladimir the Great, sent emissaries to find a... (shrink)

Social learning has been shown to be an evolutionarily adaptive strategy, but it can be implemented via many different cognitive mechanisms. The adaptive advantage of social learning depends crucially on the ability of each learner to obtain relevant and accurate information from informants. The source of informants’ knowledge is a particularly important cue for evaluating advice from multiple informants; if the informants share the source of their information or have obtained their information from each other, then their testimony is statistically (...) dependent and may be less reliable than testimony from informants who do not share information. In this study, we use a Bayesian model to determine how rational learners should incorporate the effects of shared information when learning from other people, conducting three experiments that examine whether human learners behave similarly. We find that people are sensitive to a number of different patterns of dependency, supporting the use of a sophisticated strategy for social learning that goes beyond copying the majority, and broadening the situations in which social learning is likely to be an adaptive strategy.

Detailed studies of people who have experienced the Capgras delusion (the delusion that certain other people, usually close relatives, have been replaced by impostors) have led to advances in constructing an account which can deal with the basic symptomatology, testing alternative possibilities, generating and testing non‐trivial predictions, and broadening the scope of the basic account to encompass other delusions. This paper outlines these developments. It uses them to explore implications for understanding the formation and maintenance of beliefs, and to discuss (...) basic principles of what has come to be known as cognitive neuropsychiatry.

Central to Spinoza’s ethical theory is a model of human nature: the model of the free man. In this paper I argue that the idea of the free man is an inadequate idea when this is understood as the idea of a perfectly free finite thing. But when properly understood--that is, when the idea of the free man is understood as the idea of the perfection of our nature and power--the idea of the free man is a way of conceiving (...) God and is, as such, an adequate idea. (shrink)

An array of new cases of lies is presented in support of the idea that lying does not require an intention to be deceptive. The crucial feature of these cases is that the agents who lie have some sort of motivation to lie alternative to an intention to be deceptive. Such alternative motivation comes in multiple varieties, such that we should think that the possibility of lying without an intention to be deceptive is common.

According to a widely accepted reading of the "Ethics," Spinoza subscribes to a desire-satisfaction theory of value. A desire-satisfaction theory says that what has value is the satisfaction of one’s desires and whatever leads to the satisfaction of one’s desires. In this paper I argue that this standard reading is incorrect, and I show that in Spinoza’s view the foundation of what is truly valuable is the perfection of a person’s essence, not the satisfaction of a person’s desires.

Distributivism holds that private property should be widely distributed among as many as possible and that such a distribution best serves the common good. This paper applies a distributist approach rooted in subsidiarity to the contemporary issue of the unaffordability of single-family homes and the impact of investors buying up more single-family homes, increasing their own wealth at the expense of typical home buyers. Here, we will first consider multiple factors in the housing “crisis,” then highlight the impact of investors (...) on the market. Second, we will consider a critique and analysis of the situation from a distributist perspective, rooted in principles of private property, solidarity, dignity, and subsidiarity (particularly turning to G.K. Chesterton's view on the importance of home). Due consideration is given to some objections to such a distributist critique, with response. Finally, several examples of proposals and implemented practices are provided to discourage this growing trend concerning the concentration of ownership of housing by investors and to better enable homeownership by families.

Evidence has accumulated that rod activation under mesopic and scotopic light levels alters visual perception and performance. Here we review the most recent developments in the measurement of rod and cone contributions to mesopic color perception and temporal processing, with a focus on data measured using the four-primary photostimulator method that independently controls rod and cone excitations. We discuss the findings in the context of rod inputs to the three primary retinogeniculate pathways to understand rod contributions to mesopic vision. Additionally, (...) we present evidence that hue perception is possible under scotopic, pure rod-mediated conditions that involves cortical mechanisms. (shrink)

Andrew Sayer undertakes a fundamental critique of social science's difficulties in acknowledging that people's relation to the world is one of concern. As sentient beings, capable of flourishing and suffering, and particularly vulnerable to how others treat us, our view of the world is substantially evaluative. Yet modernist ways of thinking encourage the common but extraordinary belief that values are beyond reason, and merely subjective or matters of convention, with little or nothing to do with the kind of beings (...) people are, the quality of their social relations, their material circumstances or well-being. The author shows how social theory and philosophy need to change to reflect the complexity of everyday ethical concerns and the importance people attach to dignity. He argues for a robustly critical social science that explains and evaluates social life from the standpoint of human flourishing. (shrink)

Until recently, discussion of virtues in the philosophy of mathematics has been fleeting and fragmentary at best. But in the last few years this has begun to change. As virtue theory has grown ever more influential, not just in ethics where virtues may seem most at home, but particularly in epistemology and the philosophy of science, some philosophers have sought to push virtues out into unexpected areas, including mathematics and its philosophy. But there are some mathematicians already there, ready to (...) meet them, who have explicitly invoked virtues in discussing what is necessary for a mathematician to succeed. In both ethics and epistemology, virtue theory tends to emphasize character virtues, the acquired excellences of people. But people are not the only sort of thing whose excellences may be identified as virtues. Theoretical virtues have attracted attention in the philosophy of science as components of an account of theory choice. Within the philosophy of mathematics, and mathematics itself, attention to virtues has emerged from a variety of disparate sources. Theoretical virtues have been put forward both to analyse the practice of proof and to justify axioms; intellectual virtues have found multiple applications in the epistemology of mathematics; and ethical virtues have been offered as a basis for understanding the social utility of mathematical practice. Indeed, some authors have advocated virtue epistemology as the correct epistemology for mathematics (and perhaps even as the basis for progress in the metaphysics of mathematics). This topical collection brings together several of the researchers who have begun to study mathematical practices from a virtue perspective with the intention of consolidating and encouraging this trend.

In Part 4 of his "Ethics," Spinoza puts forward and defends what might appear to be the controversial Hobbesean thesis that the desire to prolong one’s life is the basis of virtue (i.e., E4p22). Indeed there is a tradition of commentators offering an egoistic, Hobbesean interpretation of Spinoza’s ethical theory. In this paper, however, I argue that we should not understand Spinozistic self-preservation in the commonsense, empiricist sense of prolonging our lives. Instead I argue that, for Spinoza, self-preservation is a (...) matter of perfection-preservation and perfection-enhancement, which does not essentially involve extending the duration of an individual’s existence.

A list of resources for virtue theories of argumentation. Last updated October 31st, 2023.

The social sciences, and particularly economics, play an important role in business. This article reviews the account of the interdisciplinary conversation between Catholic Social Teaching and the social sciences (especially economics) over the last century, and describes Benedict XVI’s development of this account in Caritas in Veritate . Over time the popes recognized that the technical approach of economics was a barrier to fruitful collaboration between economics and Catholic Social Teaching, both because the economic approach is reductionist, and because modern (...) social science is skeptical of comprehensive accounts of human nature. Through an appeal to charity in truth, one can deduce from Caritas in Veritate that economists, along with business and management theorists, need to take seriously the project of reflecting on and promoting true human goods in society. To love the person one must reflect on what is truly good for the person; to discover the true good of the person, one must love the person. (shrink)

Deep disagreements are characteristically resistant to rational resolution. This paper explores the contribution a virtue theoretic approach to argumentation can make towards settling the practical matter of what to do when confronted with apparent deep disagreement, with particular attention to the virtue of courage.

Recent literature on epistemic innocence develops the idea that a defective cognitive process may nevertheless merit special consideration insofar as it confers an epistemic benefit that would not otherwise be available. For example, confabulation may be epistemically innocent when it makes a subject more likely to form future true beliefs or helps her maintain a coherent self-concept. I consider the role of confabulation in typical cases of interpersonal gaslighting, and argue that confabulation will not be epistemically innocent in such cases (...) even if it does preserve a coherent self-concept or belief-set for the subject. Analyzing the role of confabulation in gaslighting illustrates its role in on-going interpersonal relationships, and augments already growing evidence that confabulation may be quite widespread. The role of confabulation in gaslighting shows that whether confabulation confers epistemic benefits will depend greatly on the interpersonal context in which it is deployed, while whether a coherent self-concept is epistemically beneficial will depend to a great extent on the content of that self-concept. This shows that the notion of an epistemically harmful or beneficial feature of a cognitive process can and should be further clarified, and that doing so has both theoretical and practical advantages in understanding epistemic innocence itself.

The influence that philosophy of science has had on scientific practice is as controversial as it is undeniable, especially in the case of biology. The dynamic between philosophy and biology as disciplines has developed along two different lines that can be characterized as 'paternal', on the one hand, and more 'fraternal', on the other. The role Popperian principles of demarcation and falsifiability have played in both the systematics community as well as the ongoing evolution-creation debates illustrate these contrasting forms of (...) interdisciplinary engagement, underscoring the influence philosophy of science in shaping our contemporary understanding of biology in the North American context. However, a strict disciplinary distinction between philosophy and science may itself be a false dichotomy that risks hampering future development of the biological sciences. By actively engaging with philosophical considerations as an integral part of their scientific practice, nineteenth-century biologists offer an interesting counterpoint to current trends of overspecialization and provide a model of scientists who avoided extremes of antagonism with, or subservience to, philosophy.

Few automated legal reasoning systems have been developed in domains of law in which a judicial decision maker has extensive discretion in the exercise of his or her powers. Discretionary domains challenge existing artificial intelligence paradigms because models of judicial reasoning are difficult, if not impossible to specify. We argue that judicial discretion adds to the characterisation of law as open textured in a way which has not been addressed by artificial intelligence and law researchers in depth. We demonstrate that (...) systems for reasoning with this form of open texture can be built by integrating rule sets with neural networks trained with data collected from standard past cases. The obstacles to this approach include difficulties in generating explanations once conclusions have been inferred, difficulties associated with the collection of sufficient data from past cases and difficulties associated with integrating two vastly different paradigms. A knowledge representation scheme based on the structure of arguments proposed by Toulmin has been used to overcome these obstacles. The system, known as Split Up, predicts judicial decisions in property proceedings within family law in Australia. Predictions from the system have been compared to those from a group of lawyers with favourable results. (shrink)

The traditional view of evidence in mathematics is that evidence is just proof and proof is just derivation. There are good reasons for thinking that this view should be rejected: it misrepresents both historical and current mathematical practice. Nonetheless, evidence, proof, and derivation are closely intertwined. This paper seeks to tease these concepts apart. It emphasizes the role of argumentation as a context shared by evidence, proofs, and derivations. The utility of argumentation theory, in general, and argumentation schemes, in particular, (...) as a methodology for the study of mathematical practice is thereby demonstrated. Argumentation schemes represent an almost untapped resource for mathematics education. Notably, they provide a consistent treatment of rigorous and non-rigorous argumentation, thereby working to exhibit the continuity of reasoning in mathematics with reasoning in other areas. Moreover, since argumentation schemes are a comparatively mature methodology, there is a substantial body of existing work to draw upon, including some increasingly sophisticated software tools. Such tools have significant potential for the analysis and evaluation of mathematical argumentation. The first four sections of the paper address the relationships of evidence to proof, proof to derivation, argument to proof, and argument to evidence, respectively. The final section directly addresses some of the educational implications of an argumentation scheme account of mathematical reasoning. (shrink)

Twenty years ago, Richard Boyd suggested that physicalism could be formulated by appeal to a notion of realization, with no appeal to the identity of the non-physical with the physical. In (Melnyk 2003), I developed this suggestion at length, on the basis of one particular account of realization. I now ask what happens if you try to formulate physicalism on the basis of other accounts of realization, accounts due to LePore and Loewer and to Shoemaker. Having explored two new formulations (...) of physicalism, I conclude that my 2003 formulation remains the most promising. (shrink)

I intend to bring recent work applying virtue theory to the study of argument to bear on a much older problem, that of disagreements that resist rational resolution, sometimes termed "deep disagreements". Just as some virtue epistemologists have lately shifted focus onto epistemic vices, I shall argue that a renewed focus on the vices of argument can help to illuminate deep disagreements. In particular, I address the role of arrogance, both as a factor in the diagnosis of deep disagreements and (...) as an obstacle to their mutually acceptable resolution. Arrogant arguers are likely to make any disagreements to which they are party seem deeper than they really are and arrogance impedes the strategies that we might adopt to resolve deep disagreements. As a case in point, since arrogant or otherwise vicious arguers cannot be trusted not to exploit such strategies for untoward ends, any policy for deep disagreement amelioration must require particularly close attention to the vices of argument, lest they be exploited by the unscrupulous.

In their account of theory change in logic, Aberdein and Read distinguish 'glorious' from 'inglorious' revolutions--only the former preserves all 'the key components of a theory' [1]. A widespread view, expressed in these terms, is that empirical science characteristically exhibits inglorious revolutions but that revolutions in mathematics are at most glorious [2]. Here are three possible responses: 0. Accept that empirical science and mathematics are methodologically discontinuous; 1. Argue that mathematics can exhibit inglorious revolutions; 2. Deny that inglorious revolutions are (...) characteristic of science. Where Aberdein and Read take option 1, option 2 is preferred by Mizrahi [3]. This paper seeks to resolve this disagreement through consideration of some putative mathematical revolutions.

Virtue theories have lately enjoyed a modest vogue in the study of argumentation, echoing the success of more far-reaching programmes in ethics and epistemology. Virtue theories of argumentation (VTA) comprise several conceptually distinct projects, including the provision of normative foundations for argument evaluation and a renewed focus on the character of good arguers. Perhaps the boldest of these is the pursuit of the fully satisfying argument, the argument that contributes to human flourishing. This project has an independently developed epistemic analogue: (...) eudaimonistic virtue epistemology. Both projects stress the importance of widening the range of cognitive goals beyond, respectively, cogency and knowledge; both projects emphasize social factors, the right sort of community being indispensable for the cultivation of the intellectual virtues necessary to each project. This paper proposes a unification of the two projects by arguing that the intellectual good life sought by eudaimonistic virtue epistemologists is best realized through the articulation of an account of argumentation that contributes to human flourishing.

Virtue theories of argumentation (VTA) emphasize the roles arguers play in the conduct and evaluation of arguments, and lay particular stress on arguers’ acquired dispositions of character, that is, virtues and vices. The inspiration for VTA lies in virtue epistemology and virtue ethics, the latter being a modern revival of Aristotle’s ethics. Aristotle is also, of course, the father of Western logic and argumentation. This paper asks to what degree Aristotle may thereby be claimed as a forefather by VTA.

This chapter focuses on alternative logics. It discusses a hierarchy of logical reform. It presents case studies that illustrate particular aspects of the logical revisionism discussed in the chapter. The first case study is of intuitionistic logic. The second case study turns to quantum logic, a system proposed on empirical grounds as a resolution of the antinomies of quantum mechanics. The third case study is concerned with systems of relevance logic, which have been the subject of an especially detailed reform (...) program. Finally, the fourth case study is paraconsistent logic, perhaps the most controversial of serious proposals. (shrink)
