We present behavioral lateralizations of spiders and ants and their probable survival value. They clearly conform to the vertebrate lateralizations reviewed by Vallortigara & Rogers and to earlier arthropod studies. We suggest two complementary reviews: differences in lesion susceptibility and muscle strength between left and right body side, and perceptual biases and predator inspection in invertebrates.

Historisch-kritische analyse van canonieke en apocriefe geschriften over Jezus en van de waarheidsclaim van het christendom.

This paper argues that liberal freedom (non-interference) is epistemologically prior to republican freedom (non-domination). I start investigate three relations between liberal and republican freedom: (i) Logical Equivalence, or the question whether republican freedom entails liberal freedom (and vice versa); (ii) Degree Supervenience, or whether changes in the degree (amount, quantity) of republican freedom are mirrored by changes in the degree of liberal freedom (and vice versa); and (iii) Epistemological Priority, that is, whether knowledge about arrangements of republican freedom presupposes knowledge (...) about arrangements of liberal freedom. If Logical Equivalence holds, liberals are right to claim that republicans have not introduced a new concept of freedom. It is easy to see, though, that Logical Equivalence does not hold. If Degree Supervenience holds, liberals can maintain that while republican freedom is a new concept of freedom, fostering or promoting it is not very different from fostering or promoting liberal freedom. Degree Supervenience does not hold either, though, and as a result two straightforward counterarguments against republican freedom fail. Yet, I argue, first, that the relation of Epistemological Priority holds: knowing something about arrangements of republican freedom presupposes that you know something about arrangements of liberal freedom. Using Epistemological Priority, I show, second, that the benefits claimed for republican freedom over and above liberal freedom (it minimizes the need for strategic deference, it minimizes uncertainty, and it minimizes subordination) can be accounted for in purely liberal terms.

The global financial crisis has led to a surprising interest in professional oaths in business. Examples are the MBA Oath, the Economist’s Oath and the Dutch Banker’s Oath, which senior executives in the financial services industry in the Netherlands have been obliged to swear since 2010. This paper is among the first to consider oaths from the perspective of business ethics. A framework is presented for analysing oaths in terms of their form, their content and the specific contribution they make (...) to business ethics management: oaths may foster professionalism, facilitate moral deliberation and enhance compliance. This framework is used to analyse and evaluate the MBA Oath, the Economist’s Oath and the Banker’s Oath as well as various other similar initiatives. (shrink)

This paper presents an argument for the value of privacy that is based on a purely negative concept of freedom only. I show that privacy invasions may decrease a person’s negative freedom as well as a person’s knowledge about the negative freedom she possesses. I argue that not only invasions that lead to actual interference, but also invasions that lead to potential interference (many cases of identity theft) constitute actual harm to the invadee’s liberty interests, and I critically examine the (...) courts’ reliance on a principle of ‘no harm, no foul’ in recent data breach cases. Using a number of insights from the psychology of human belief, I also show that the liberal claim for protection of privacy is strengthened by the observation that often the privacy invader cannot be held responsible for the influence on the invadee’s negative freedom.

Susan Hurley has argued against a well known argument for freedom of speech, the argument from autonomy, on the basis of two hypotheses about violence in the media and aggressive behaviour. The first hypothesis says that exposure to media violence causes aggressive behaviour; the second, that humans have an innate tendency to copy behaviour in ways that bypass conscious deliberation. I argue, first, that Hurley is not successful in setting aside the argument from autonomy. Second, I show that the empirical (...) data are irrelevant to statutory regulation of media violence. They do not yield a sufficiently strong correlation between exposure to media violence and non-autonomously copied criminal violence, and they do not yield a way ex ante to individuate the viewers who will be affected by media violence.

Using epistemic logic, we provide a non-probabilistic way to formalise payoff uncertainty, that is, statements such as ‘player i has approximate knowledge about the utility functions of player j.’ We show that on the basis of this formalisation common knowledge of payoff uncertainty and rationality (in the sense of excluding weakly dominated strategies, due to Dekel and Fudenberg (1990)) characterises a new solution concept we have called ‘mixed iterated strict weak dominance.’.

This article provides an outsider perspective on the scientificity of legal studies. First, I argue that the presence of controversies does not mean that legal studies lack the status of a genuine science. Astronomy, mathematics, and economics have their controversies, too. Second, I show that non-empirical, non-normative research is no less scientific than empirical research. This is illustrated by work in mathematical logic. Third, I demonstrate the same claim for non-empirical, normative research.Here the example is research on social contract theories (...) by means of gametheoretic models. (shrink)

This Chapter studies legislative initiatives around sustainable finance deriving from the Action Plan: Financing Sustainable Growth (also called ‘Sustainable Finance Action Plan’, ‘Action Plan’ henceforth), published by the European Commission (‘Commission’) in 2018 (Communication 2018/97). I evaluate various instruments proposed in the Action Plan, using a reflexive law approach coupled with insights from business ethics and epistemology (De Bruin, 2013, 2015). I point to the challenges such an approach encounters, and offer suggestions how to address them. Reflexive law approaches to (...) legislation (Farber 1994, Hess 1999, Orts 1994, Farmer & Teubner 1994) acknowledge the limits of law as an instrument to realize social or political goals, and stress the need to encourage self-reflection and transparency among stakeholders through procedural rather than ‘command-and-control’ legislation. Typical reflexive law instruments involve disclosure, reporting, and labelling. Examining the Action Plan, I show that the main legislative instruments it puts forward are reflexive. I use empirical and theoretical work that challenges the effectiveness of some of these instruments. Drawing on recent work from behavioural economics I suggest that these problems may be overcome once we integrate more fully in reflexive law what it means for people ‘reflectively’ to recruit evidence and gather knowledge, and once we appreciate the value knowledge has over and above mere belief. My argument here is not so much to the effect that more interventionist regulatory tools are needed (they are dearly needed, but that is not the point here). Rather I argue that once a regulator opts for a reflexive law approach, a richer notion of information should be deployed. I call this ‘epistemic’ instead of ‘reflexive’ law. The Chapter gives some background information about the Action Plan, introduces the core ideas of reflexive law, shows how the Action Plan is reflexive law par excellence, considers the challenges, and offers a few modest suggestions.

We present an argument against a standard evidentialist position on the ethics of belief. We argue that sometimes a person merits criticism for holding a belief even when that belief is well supported by her evidence in any relevant sense. We show how our argument advances the case for anti-evidentialism in the light of other arguments presented in the recent literature, and respond to a set of possible evidentialist rejoinders.

The ethical practices of credit rating agencies, particularly following the 2008 financial crisis, have been subject to extensive analysis by economists, ethicists, and policymakers. We raise a novel issue facing CRAs that has to do with a problem concerning the transmission of epistemic status of ratings from CRAs to the beneficiaries of the ratings, and use it to provide a new challenge for regulators. Building on recent work in philosophy, we argue that since CRAs have different stakes than the beneficiaries (...) of the ratings in the ratings being accurate, what counts as knowledge concerning credit risk for a CRA may not count as knowledge for the beneficiary. Further, as it stands, many institutional investors are bound by law to make some of their investment decisions dependent on the ratings of officially recognized CRAs. We argue that the observation that the epistemic status of ratings does not transmit from CRAs to beneficiaries makes salient a new challenge for those who think current regulation regarding the CRAs is prudentially justified, namely, to show that the harm caused by acting on a rating that does not have epistemic status for beneficiaries is compensated by the benefit from them acting on a CRA rating that does have epistemic status for the CRA. Unlike most other commentators, therefore, we offer a defeasible reason to drop references to CRAs in prudential regulation of the financial industry. (shrink)

In this topical book, Boudewijn de Bruin examines the ethical 'blind spots' that lay at the heart of the global financial crisis. He argues that the most important moral problem in finance is not the 'greed is good' culture, but rather the epistemic shortcomings of bankers, clients, rating agencies and regulators. Drawing on insights from economics, psychology and philosophy, de Bruin develops a novel theory of epistemic virtue and applies it to racist and sexist lending practices, subprime mortgages, CEO (...) hubris, the Madoff scandal, professionalism in accountancy and regulatory outsourcing of epistemic responsibility. With its multidisciplinary reach, Ethics and the Global Financial Crisis will appeal to scholars working in philosophy, business ethics, economics, psychology and the sociology of finance. The many concrete examples and case studies mean that this book will also prove useful to policy-makers and regulators. (shrink)

Game theory is the mathematical study of strategy and conflict. It has wide applications in economics, political science, sociology, and, to some extent, in philosophy. Where rational choice theory or decision theory is concerned with individual agents facing games against nature, game theory deals with games in which all players have preference orderings over the possible outcomes of the game. This paper gives an informal introduction to the theory and a survey of applications in diverse branches of philosophy. No criticism (...) is reviewed. Game theory is shown at work in discussions about epistemological dependence, liberalism and efficiency, Hume’s concept of convention, morality and rationality, and distributive justice and egalitarianism. A guide to the literature provides hints at applications in collective intentionality, epistemology, ethics, history of philosophy, logic, philosophy of language, and political philosophy. (shrink)

This paper presents two studies on the development and validation of a ten-item scale of epistemic vice and the relationship between epistemic vice and misinformation and fake news. Epistemic vices have been defined as character traits that interfere with acquiring, maintaining, and transmitting knowledge. Examples of epistemic vice are gullibility and indifference to knowledge. It has been hypothesized that epistemically vicious people are especially susceptible to misinformation and conspiracy theories. We conducted one exploratory and one confirmatory observational survey study on (...) Amazon Mechanical Turk among people living in the United States. We show that two psychological traits underlie the range of epistemic vices that we investigated: indifference to truth and rigidity. Indifference manifests itself in a lack of motivation to find the truth. Rigidity manifests itself in being insensitive to evidence. We develop a scale to measure epistemic vice with the subscales indifference and rigidity. The Epistemic Vice Scale is internally consistent; has good convergent, divergent, and discriminant validity; and is strongly associated with the endorsement of misinformation and conspiracy theories. Epistemic vice explains additional variance in the endorsement of misinformation and conspiracy theories over and above demographic and related psychological concepts and shows medium to large effect sizes across outcome measures. We demonstrate that epistemic vice differs from existing psychological constructs, and show that the scale can explain individual differences in dealing with misinformation and conspiracy theories. We conclude that epistemic vice might contribute to “postfactive” ways of thinking. (shrink)

Why are mistaken beliefs about Covid-19 so prevalent? Political identity, education and other demographic variables explain only a part of individual differences in the susceptibility to Covid-19 misinformation. This paper focuses on another explanation: epistemic vice. Epistemic vices are character traits that interfere with acquiring, maintaining, and transmitting knowledge. If the basic assumption of vice epistemology is right, then people with epistemic vices such as indifference to the truth or rigidity in their belief structures will tend to be more susceptible (...) to believing Covid-19 misinformation. We carried out an observational study (US sample, n = 998) in which we measured the level of epistemic vice of participants using a novel Epistemic Vice Scale. We also asked participants questions eliciting the extent to which they subscribe to myths and misinformation about Covid-19. We find overwhelming evidence to the effect that epistemic vice is associated with susceptibility to Covid-19 misinformation. In fact, the association turns out to be stronger than with political identity, educational attainment, scores on the Cognitive Reflection Test, personality, dogmatism, and need for closure. We conclude that this offers evidence in favor of the empirical presuppositions of vice epistemology. (shrink)

This paper applies emerging research on epistemic virtues to business ethics. Inspired by recent work on epistemic virtues in philosophy, I develop a view in which epistemic virtues contribute to the acquisition of knowledge that is instrumentally valuable in the realisation of particular ends, business ends in particular. I propose a conception of inquiry according to which epistemic actions involve investigation, belief adoption and justification, and relate this to the traditional ‘justified true belief’ analysis of knowledge. I defend the view (...) that epistemic virtues enable and/or motivate people to perform epistemic actions. An examination of the key epistemic virtues of love of knowledge, epistemic courage, temperance, justice, generosity and humility provides some initial evidence suggesting that the way epistemic virtues enable or motivate is by countering a number of biases that have been uncovered by behavioural economics, and also indicates ways in which the instrumental epistemic value view is superior to other approaches to epistemic virtue offered in the literature.

Cloud computing is rapidly gaining traction in business. It offers businesses online services on demand (such as Gmail, iCloud and Salesforce) and allows them to cut costs on hardware and IT support. This is the first paper in business ethics dealing with this new technology. It analyzes the informational duties of hosting companies that own and operate cloud computing datacenters (e.g., Amazon). It considers the cloud services providers leasing ‘space in the cloud’ from hosting companies (e.g, Dropbox, Salesforce). And it (...) examines the business and private ‘clouders’ using these services. The first part of the paper argues that hosting companies, services providers and clouders have mutual informational (epistemic) obligations to provide and seek information about relevant issues such as consumer privacy, reliability of services, data mining and data ownership. The concept of interlucency is developed as an epistemic virtue governing ethically effective communication. The second part considers potential forms of government restrictions on or proscriptions against the development and use of cloud computing technology. Referring to the concept of technology neutrality, it argues that interference with hosting companies and cloud services providers is hardly ever necessary or justified. It is argued, too, however, that businesses using cloud services (banks, law firms, hospitals etc. storing client data in the cloud, e.g.) will have to follow rather more stringent regulations.

Financial incentives, learning, group consultation, and increased experimental control are among the experimental techniques economists have successfully used to deflect the behavioral challenge posed by research conducted by such scholars as Tversky and Kahneman. These techniques save the economic armchair to the extent that they align laypeople judgments with economic theory by increasing cognitive effort and reflection in experimental subjects. It is natural to hypothesize that a similar strategy might work to address the experimental or restrictionist challenge to armchair philosophy. (...) To test this hypothesis, a randomized controlled experiment was carried out, as well as two lab experiments. Three types of knowledge attribution tasks were used. No support for the hypothesis was found. The paper describes the close similarities between the economist’s response to the behavioral challenge, and the expertise defense against the experimental challenge, and presents the experiments, results, and an array of robustness checks. The upshot is that these results make the experimental challenge all the more forceful. (shrink)

Does game theory—the mathematical theory of strategic interaction—provide genuine explanations of human behaviour? Can game theory be used in economic consultancy or other normative contexts? Explaining Games: The Epistemic Programme in Game Theory—the first monograph on the philosophy of game theory—is an attempt to combine insights from epistemic logic and the philosophy of science to (...) investigate the applicability of game theory in such fields as economics, philosophy and strategic consultancy. I prove new mathematical theorems about the beliefs, desires and rationality principles of individual human beings, and explore in detail the logical form of game theory as it is used in explanatory and normative contexts. I argue that game theory reduces to rational choice theory if used as an explanatory device, and that game theory is nonsensical if used as a normative device. A provocative account of the history of game theory reveals that this is not bad news for all of game theory, though. Two central research programmes in game theory tried to find the ultimate characterisation of strategic interaction between rational agents. Yet, while the Nash Equilibrium Refinement Programme has done badly thanks to such research habits as overmathematisation, model-tinkering and introversion, the Epistemic Programme, I argue, has been rather successful in achieving this aim. "The 'epistemic' approach to game theory has emerged over the past twenty-five years. What is this approach? How does it differ from the conventional equilibrium-based approach to game theory? What have been its strengths and weaknesses to date? To find out, read this comprehensive and excellently written account". Adam Brandenburger, J. P. Valles Professor of Business Economics and Strategy, Stern School of Business, New York University "Reading Boudewijn de Bruin's book should be rewarding both for game theorists interested in the conceptual foundations of their discipline and for philosophers who want to learn more about formal analysis of strategic interaction.

To commemorate 40 years since the founding of the Journal of Business Ethics, the editors in chief of the journal have invited the editors to provide commentaries on the future of business ethics. This essay comprises a selection of commentaries aimed at creating dialogue around the theme Ethics at the centre of global and local challenges. For much of the history of the Journal of Business Ethics, ethics was seen within the academy as a peripheral aspect of business. However, in (...) recent years, the stakes have risen dramatically, with global and local worlds destabilized by financial crisis, climate change, internet technologies and artificial intelligence, and global health crises. The authors of these commentaries address these grand challenges by placing business ethics at their centre. What if all grand challenges were framed as grand ethical challenges? Tanusree Jain, Arno Kourula and Suhaib Riaz posit that an ethical lens allows for a humble response, in which those with greater capacity take greater responsibility but remain inclusive and cognizant of different voices and experiences. Focussing on business ethics in connection to the grand challenge of environmental emergencies, Steffen Böhm introduces the deceptively simple yet radical position that business is nature, and nature is business. His quick but profound side-step from arguments against human–nature dualism to an ontological undoing of the business–nature dichotomy should have all business ethics scholars rethinking their “business and society” assumptions. Also, singularly concerned with the climate emergency, Boudewijn de Bruin posits a scenario where, 40 years from now, our field will be evaluated by its ability to have helped humanity emerge from this emergency. He contends that Milieudefensie v. Royal Dutch Shell illustrates how human rights take centre stage in climate change litigation, and how business ethics enters the courtroom. From a consumer ethics perspective, Deirdre Shaw, Michal Carrington and Louise Hassan argue that ecologically sustainable and socially just marketplace systems demand cultural change, a reconsideration of future interpretations of “consumer society”, a challenge to the dominant “growth logic” and stimulation of alternative ways to address our consumption needs. Still concerned with global issues, but turning attention to social inequalities, Nelarine Cornelius links the capability approach to global and corporate governance, arguing that CA will continue to lie at the foundation of human development policy, and, increasingly, CSR and corporate governance. Continuing debate on the grand challenges associated with justice and equality, Laurence Romani identifies a significant shift in the centrality of business ethics in debates on managing differences, positing that dialogue between diversity management and international management can ground future debate in business ethics. Finally, the essay concludes with a commentary by Charlotte Karam and Michelle Greenwood on the possibilities of feminist-inspired theories, methods, and positionality for many spheres of business ethics, not least stakeholder theory, to broaden and deepen its capacity for nuance, responsiveness, and transformation. In the words of our commentators, grand challenges must be addressed urgently, and the Journal of Business Ethics should be at the forefront of tackling them. (shrink)

Situationists maintain that psychological evidence (e.g., the well-known Good Samaritan experiment) challenges a key assumption of virtue ethics, namely that virtuous people display cross-situational consistency of behavior. This situationist critique is frequently thought to pose a serious threat to virtue ethics. Virtue ethicists have so far mainly put forward conceptual rather than empirical arguments against situationism. In this paper, we examine the extent to which a plausible empirical argument can be developed against situationism, and in favor of virtue ethics. We (...) note that such an argument will naturally entail empirical simplification, and consequently concessions from both sides of the debate will be required. We argue, however, that with such concessions in place, the debate between situationists and virtue ethicists can be captured by a claim about the way that virtuous behavior may change when situations change. We report the results of an experiment (conducted twice, for replication) showing how social science methods can be introduced to the situationism debate to test such a claim empirically. Our results offer tentative support for eudaemonist and agent-based varieties (but not for target-centered) versions of virtue ethics. (shrink)

This chapter argues for deregulation of the credit-rating market. Credit-rating agencies are supposed to contribute to the informational needs of investors trading bonds. They provide ratings of debt issued by corporations and governments, as well as of structured debt instruments (e.g. mortgage-backed securities). As many academics, regulators, and commentators have pointed out, the ratings of structured instruments turned out to be highly inaccurate, and, as a result, they have argued for tighter regulation of the industry. This chapter shows, however, that (...) the role of credit-rating agencies in achieving justice in finance is not as great as these commentators believe. It therefore argues instead for deregulation. Since the 1930s, lawgivers have unjustifiably elevated the rating agencies into official, legally binding sources of information concerning credit risk, thereby unjustifiably causing many institutional investors to outsource their epistemic responsibilities, that is, their responsibility to investigate credit risk themselves.

This article applies philosophical work on epistemic injustice and cognate concepts to study gender and racial disparity in financial markets. Members of disadvantaged groups often receive inferior financial services. In most jurisdictions, it is illegal to provide discriminatorily disparate treatment to groups defined by gender and skin colour. Racial disparity in financial services is generally considered to be discriminatory. The standard view among most regulators is that gender disparity is not discriminatory, though. Through an analysis of various exemplary cases, I (...) propose testimonial injustice as a candidate explanation for some of the existing forms of racial disparity found in financial services. I show how prejudices about gender and finance decrease epistemic self-confidence, and how this leads to gender disparity. And I consider particularly intractable forms of self-fulfilling testimonial injustice. (shrink)

Climate change threatens humanity more than anything else. If we talk of nationalism, we ought therefore consider its pros and cons in light of the climate emergency. Anatol Lieven believes that civic nationalism along the lines of Chaim Gans, David Miller, and Yuli Tamir helps combat global warming. He thinks that when nationalists recognize that climate change is just as threatening to the survival of their nation-state as wars, they will make the sacrifices necessary to avert the threat. In this (...) view, the military has an important role, and migration will have to be restricted. In this paper, I show that this solution is at best highly risky, and more probably unsound. However difficult it will be to realize, addressing climate change must be based on international cooperation, normatively grounded in human rights. I show how international law rather than civic nationalism gives us examples of how to go forward. (shrink)

This paper contributes to an increasing literature strengthening the connection between epistemic logic and epistemology (Van Benthem, Hendricks). I give a survey of the most important applications of epistemic logic in epistemology. I show how it is used in the history of philosophy (Steiner's reconstruction of Descartes' sceptical argument), in solutions to Moore's paradox (Hintikka), in discussions about the relation between knowledge and belief (Lenzen) and in an alleged refutation of verificationism (Fitch) and I examine an early argument about the (...) (im)possibility of epistemic logic (Hocutt). Subsequently, I deal with interpretive questions about epistemic logic that, although implicitly, already appeared in the first section. I contend that a conception of epistemic logic as a theory of knowledge assertions is incoherent, and I argue that it does not make sense to adopt a normative interpretation of epistemic logic. Finally, I show ways to extend epistemic logic with other branches of philosophical logic so as to make it useful for some epistemological questions. Conditional logics and logics of public announcement are used to understand causal theories of knowledge and versions of reliabilism. Temporal logic helps understand some dynamic aspects of knowledge as well as the verificationist thesis. (shrink)

In this chapter, one considers finance at its very foundations, namely, at the place where assumptions are being made about the ways to measure the two key ingredients of finance: risk and return. It is well known that returns for a large class of assets display a number of stylized facts that cannot be squared with the traditional views of 1960s financial economics (normality and continuity assumptions, i.e. Brownian representation of market dynamics). Despite the empirical counterevidence, normality and continuity assumptions (...) were part and parcel of financial theory and practice, embedded in all financial practices and beliefs. Our aim is to build on this puzzle for extracting some clues revealing the use of one research strategy in academic community, model tinkering defined as a particular research habit. We choose to focus on one specific moment of the scientific controversies in academic finance: the ‘leptokurtic crisis’ opened by Mandelbrot in 1962. The profoundness of the crisis came from the angle of the Mandelbrot’s attack: not only he emphasized an empirical inadequacy of the Brownian representation, but also he argued for an inadequate grounding of this representation. We give some insights in this crisis and display the model tinkering strategies of the financial academic community in the 1970s and the 1980s. (shrink)

This paper presents new evidence on the impact of socioeconomic status and education on knowledge attribution. I examine a variety of cases, including vignettes where agents have been Gettiered, have false beliefs, and possess knowledge. Early work investigated whether SES might be associated with knowledge attribution :429–460, 2001; Seyedsayamdost in Episteme 12:95–116, 2014). But these studies used college education as a dummy variable for SES. I use the recently developed Great British Class Survey :219–250, 2013) to measure SES. The paper (...) reports evidence against an association between SES and patterns of knowledge ascription, and reports mixed evidence about education effects. (shrink)

Postnatally, heart muscle cells almost completely lose their ability to divide, which makes their loss after trauma irreversible. Potential repair by cell grafting or mobilizing endogenous cells is of particular interest for possible treatments for heart disease, where the poor capacity for cardiomyocyte proliferation probably contributes to the irreversibility of heart failure. Knowledge of the molecular mechanisms that underly formation of heart muscle cells might provide opportunities to repair the diseased heart by induction of (trans) differentiation of endogenous or exogenous (...) cells into heart muscle cells. We briefly review the molecular mechanisms involved in early development of the linear heart tube by differentiation of mesodermal cells into heart muscle cells. Because the initial heart tube does not comprise all the cardiac compartments present in the adult heart, heart muscle cells are added to the distal borders of the tube and within the tube. At both distal borders, mesodermal cell are recruited into the cardiac lineage and, within the heart tube, muscular septa are formed. In this review, the relative late additions of heart muscle cells to the linear heart tube are described and the potential underlying molecular mechanisms are discussed. BioEssays 26:248–261, 2004.

We develop a logical system that captures two different interpretations of what extensive games model, and we apply this to a long-standing debate in game theory between those who defend the claim that common knowledge of rationality leads to backward induction or subgame perfect (Nash) equilibria and those who reject this claim. We show that a defense of the claim à la Aumann (1995) rests on a conception of extensive game playing as a one-shot event in combination with a principle (...) of rationality that is incompatible with it, while a rejection of the claim à la Reny (1988) assumes a temporally extended, many-moment interpretation of extensive games in combination with implausible belief revision policies. In addition, the logical system provides an original inductive and implicit axiomatization of rationality in extensive games based on relations of dominance rather than the usual direct axiomatization of rationality as maximization of expected utility.

Using epistemic logic, we provide a non-probabilistic way to formalise payoff uncertainty, that is, statements such as ‘player i has approximate knowledge about the utility functions of player j.’ We show that on the basis of this formalisation common knowledge of payoff uncertainty and rationality (in the sense of excluding weakly dominated strategies, due to Dekel and Fudenberg (1990)) characterises a new solution concept we have called ‘mixed iterated strict weak dominance.’.

This paper presents an epistemological or knowledge-theoretic reinterpretation of the role of external accountants. It presents a joint epistemic agent model in which corporate management and accountants together form a source of testimonial knowledge for the firm’s stakeholders about the firm’s financial situation. Recent work from virtue epistemology is used, according to which knowledge is, roughly, true belief that is justified by way of the exercise of epistemic virtue. In the joint epistemic agent model, corporate management provides information, while the (...) accountants ensure justification. The paper argues that to ensure justification, accountants have to exercise self-regarding epistemic virtues such as open-mindedness, but also other-regarding epistemic virtues such as generosity. It is also argued that these virtues are only partly encompassed in existing professional codes of conduct. (shrink)

This paper presents a meta-ranking of philosophy journals based on existing rankings, and a new ranking of philosophy journals developed through a survey involving a thousand authors (351 respondents, data collection May 2022) of articles from the most recent issues of 40 general philosophy journals. In addition to assessing journal quality, data were gathered on various variables such as gender, age, years in academia, number of refereed publications, area of specialization, and journal affiliation (as an author or editor). Findings indicate (...) that only area of specialization and affiliation have some influence on respondents’ assessments. Authors affiliated with particular journals rate them higher than non-affiliated authors. The paper discusses criticisms of both citation-based and survey-based journal rankings, and offers words of caution regarding the practical use of rankings. (shrink)

The paper argues that the Nash Equilibrium Refinement Programme was less successful than its competitor, the Epistemic Programme. The prime criterion of success is the extent to which the programmes were able to reach the key objective guiding non-cooperative game theory for much of the twentieth century, namely, to develop a complete characterisation of the strategic rationality of economic agents in the form of the ultimate solution concept for any normal form and extensive game. The paper explains this in terms (...) of unjustified degrees of mathematisation in Nash Equilibrium Refinement Programme. While this programme’s mathematical models were often inspired by purely mathematical concerns rather than the economic phenomena they were intended to model, the Epistemic Programme’s models were developed with a keen eye to the role beliefs and desires play in strategic interaction between rational economic agents playing games; that is, their interactive epistemology. The Epistemic Programme succeeded in developing mathematical models formalising aspects of strategic interaction that remained implicit in the Nash Equilibrium Refinement Programme owing to an unjustified degree of mathematisation. As a result, the Epistemic Programme is the more successful theory.Keywords: Epistemic Programme; Game theory; Interactive epistemology; Mathematisation; Nash equilibrium. (shrink)
