This book is focused on a problem that has aroused the most controversy in recent epistemological debate, which is whether the truth can or cannot be the fundamental epistemic goal. Traditional epistemology has presupposed the centrality of truth without giving a deeper analysis. To epistemic value pluralists, the claim that truth is the fundamental value seems unjustified. Their central judgement is that we can be in a situation where we do not attain truth but something else that is also epistemically (...) valuable. In contrast, epistemic value monists are committed to the view that one can only attain something of epistemic value by attaining truth. It was necessary to rethink the long-accepted platitude that truth is our primary epistemic goal, once several objections about epistemic value were formulated. The whole debate is instructive for understanding how the epistemic value domain is structured. (shrink)

This paper concerns anti-Humean intuitions about connections in nature. It argues for the existence of a de re link that is not necessity.Some anti-Humeans tacitly assume that metaphysical necessity can be used for all sorts of anti-Humean desires. Metaphysical necessity is thought to stick together whatever would be loose and separate in a Hume world, as if it were a kind of universal superglue.I argue that this is not feasible. Metaphysical necessity might connect synchronically co-existent properties—kinds and their essential features, (...) for example—but it is difficult to see how it could also serve as the binding force for successions of events. That is, metaphysical necessity seems not to be fit for diachronic, causal affairs in which causal laws, causation, or dispositions are involved. A different anti-Humean connection in nature has to do that job.My arguments focus mainly on a debate which has been the battleground for Humean vs. anti-Humean intuitions for many decades—namely, the analysis of dispositional predicates—yet I believe (but do not argue here) that the arguments generalise to causation and causal laws straightforwardly.

This detailed 1990 book describes the light and dark adaptation of receptoral and post-receptoral mechanisms from a number of perspectives. The authors emphasise the importance of the study of achromatopsia, a rare congenital condition in which the visual mechanisms that mediate day vision are absent whilst those that mediate night vision remain intact.

Judith Shklar was a formative political thinker whose oeuvre defies traditional labels, and whose legacy is subtle but substantial. Her work emerged, as one observer has pointed out, between the "end of ideology" discussions of the 1950s and the early 1990s discussion of the "end of history." Shklar contributed significantly to American political thought by arguing for a new, more skeptical and stripped-down version of liberalism that intends to bring political theory and real-life experiences closer together. This book is the (...) first to comprehensively explore how Shklar's ideas emerged, how her political theory developed, and the impact and legacy she left behind."--Publisher's website. (shrink)

According to the standard view in philosophy, intentionality is the mark of genuine action. In psychology, human cognition and agency are now widely explained in terms of the workings of two distinct systems (or types of processes), and intentionality is not a central notion in this dual-system theory. Further, it is often claimed, in psychology, that most human actions are automatic, rather than consciously controlled. This raises pressing questions. Does the dual-system theory preserve the philosophical account of intentional action? How (...) much of our behavior is intentional according to this view? And what is the role of consciousness? I will propose here a revised account of intentional action within the dual-system framework, and we will see that most of our behavior can qualify as intentional, even if most of it is automatic. An important lesson will be that philosophical accounts of intentional action need to pay more attention to the role of consciousness in action. (shrink)

This paper combines two ideas: (1) That the Lewisian best system analysis of lawhood (BSA) can cope with laws that have exceptions (cf. Braddon-Mitchell in Noûs 35(2):260–277, 2001; Schrenk in The metaphysics of ceteris paribus laws. Ontos, Frankfurt, 2007). (2) That a BSA can be executed not only on the mosaic of perfectly natural properties but also on any set of special science properties (cf., inter alia, Schrenk 2007, Selected papers contributed to the sections of GAP.6, 6th international congress of (...) the society for analytical philosophy. Mentis, Paderborn/Münster, 2008; Cohen and Callender in Philos Stud 145:1–34, 2009, Erkenntnis 73:427–447, 2010).

This is the first concise study to give full credit to the collaboration of works between French nobleman, writer and politician Alexis de Tocqueville (1805-59) and his travel companion and friend Gustave de Beaumont (1802-66), and puts this collaboration into its social, historical and theoretical context. It accompanies the two friends to the US and analyses the fruitful encounter between the New and the Old World that was the result of that journey, particularly in relation to emerging Atlantic democracies and (...) revolutions. This includes the hopes but also the problems and contradictions that they have come to represent. The book also follows Tocqueville and Beaumont to England, Ireland, and Algeria. It discusses their political careers and their engagement in the abolitionist movement, their fight for liberal social and political reform, as well as their futile attempt to rationalize French colonization in Algeria.

This article makes the case for a specific variety of what we call Collective Capital Institutions (CCIs), by returning to the idea of Wage-Earner Funds (WEFs) – a 1970s Swedish policy proposal designed gradually to shift ownership and control over parts of the economy to democratically controlled institutions. We identify two attractive rationales in favour of such a scheme and argue that both can fruitfully be transposed to the current worldwide economic situation. The egalitarian rationale is that WEFs could help (...) in the pursuit of equality by giving a wider set of people a stake in collectively owned companies and a right to their profits. The democratic rationale is that WEFs redistribute not only these profits, but also the power over economic decisions made within companies. We then contrast such schemes for collective capital ownership with the similar but much more privatised proposals set out in, for instance, John Rawls's idea of a ‘property-owning democracy’. We argue that CCIs ultimately are more likely to contribute to the development of the ‘sense of justice’ within society that is needed for a stable just society. We conclude that CCIs deserve a great deal more exploration in academic and political discussions of egalitarian economic systems. (shrink)

This paper explores whether it is possible to reformulate or re-interpret Lewis’s theory of fundamental laws of nature—his “best system analysis”—in such a way that it becomes a useful theory for special science laws. One major step in this enterprise is to make plausible how law candidates within best system competitions can tolerate exceptions—this is crucial because we expect special science laws to be so called “ceteris paribus laws ”. I attempt to show how this is possible and also how (...) we can thereby make the first step towards a solution for the infamous difficulties surrounding the troublesome ceteris paribus clause. The paper outlines the general ideas of the theory but also points out some of its difficulties and background assumptions. (shrink)

Recent research shows – somewhat astonishingly – that people are willing to ascribe moral blame to AI-driven systems when they cause harm [1]–[4]. In this paper, we explore the moral- psychological underpinnings of these findings. Our hypothesis was that the reason why people ascribe moral blame to AI systems is that they consider them capable of entertaining inculpating mental states (what is called mens rea in the law). To explore this hypothesis, we created a scenario in which an AI system (...) runs a risk of poisoning people by using a novel type of fertilizer. Manipulating the computational (or quasi-cognitive) abilities of the AI system in a between-subjects design, we tested whether people’s willingness to ascribe knowledge of a substantial risk of harm (i.e., recklessness) and blame to the AI system. Furthermore, we investigated whether the ascription of recklessness and blame to the AI system would influence the perceived blameworthiness of the system’s user (or owner). In an experiment with 347 participants, we found (i) that people are willing to ascribe blame to AI systems in contexts of recklessness, (ii) that blame ascriptions depend strongly on the willingness to attribute recklessness and (iii) that the latter, in turn, depends on the perceived “cognitive” capacities of the system. Furthermore, our results suggest (iv) that the higher the computational sophistication of the AI system, the more blame is shifted from the human user to the AI system. (shrink)

This chapter sheds light on a response to experimental philosophy that has not yet received enough attention: the reflection defense. According to proponents of this defense, judgments about philosophical cases are relevant only when they are the product of careful, nuanced, and conceptually rigorous reflection. The chapter argues that the reflection defense is misguided: Five studies (N>1800) are presented, showing that people make the same judgments when they are primed to engage in careful reflection as they do in the conditions (...) standardly used by experimental philosophers.

From the late seventeenth century on the idea of culture underwent a gradual transformation. Originally this concept referred essentially to the “refined” way of life of the ruling social elite. Popular culture, on the other hand, refers to the usually collective practices of groups of rural and urban workers taking the form of performance. They were not only excluded from refined culture, but it was regarded as completely unsuitable for them, potentially creating dangerous social aspirations. It is with the great (...) social transformation from feudal to bourgeois society that the idea of refined culture was replaced by that of “high culture” encompassing both the arts and the sciences: works claiming universal human significance. This “high culture” for a considerable time coexisted with the remnants of popular culture. It has been only due to the great technical advances that its true opposite, “mass culture” emerged, at the turn to twentieth century, claiming an empirical universality: being understandable and truly interesting to everyone. In economic respect, there is a competitive relation between high and mass culture. However, it is argued that there can be no cultural competition between them. For they posit differing and potentially co-existing receptive attitudes. The characterisation of this difference and the discussion of the seeming exceptions to the so-articulated conceptual scheme occupies the concluding part of this essay. (shrink)

This paper presents a series of studies (total N=579) which demonstrate that folk judgments concerning the reasonableness of decisions and actions depend strongly on whether they engender positive or negative consequences. A particular decision is deemed more reasonable in retrospect when it produces beneficial consequences than when it produces harmful consequences, even if the situation in which the decision was taken and the epistemic circumstances of the agent are held fixed across conditions. This finding is worrisome for the law, where (...) the reasonable person standard plays a prominent role. The legal concept of reasonableness is outcome-insensitive: whether the defendant acted in a reasonable fashion or not depends exclusively on her context of action, no matter how things play out. Folk judgments of reasonableness are thus inconsistent with the legal concept of reasonableness. Problematically, in common law jurisdictions, the decision whether a defendant’s behavior was reasonable or not is frequently (though not necessarily) delegated to a lay jury. (shrink)

Work has always been a significant source of ethical questions, philosophical reflection, and political struggle. Although the future of work in a sense is always at stake, the issue is particularly relevant right now, in light of the advent of advanced AI systems and the collective experience of the COVID-19 pandemic. This has reinvigorated philosophical discussion and interest in the study of the future of work. The purpose of this survey article is to provide an overview of the emerging philosophical (...) field that engages with the future of work, with a special focus on equality and justice, and to outline a research agenda that can help the field to develop further. Section 2 provides some historical context for the current surge in interest in the topic. Then, we discuss what work is and whether there is a philosophy of work (Section 3). The four main sub-debates we then turn to concern the value of work (Section 4), distributive justice and work (Section 5), productive justice (Section 6), and institutional reforms prompted by changes in how work is organized (Section 7). The final section discusses the importance of the distinction between ideal and non-ideal theory in philosophical investigations into the future of work. (shrink)

It is widely believed that at least two developments in the last third of the 20th century have given dispositionalism—the view that powers, capacities, potencies, etc. are irreducible real properties—new credibility: (i) the many counterexamples launched against reductive analyses of dispositional predicates in terms of counterfactual conditionals and (ii) a new anti-Humean faith in necessary connections in nature which, it is said, owes a lot to Kripke’s arguments surrounding metaphysical necessity. I aim to show in this paper that necessity is, (...) in fact, of little help for the dispositionalists. My argument makes use of one of the above mentioned counterexamples against Humean reduction: antidotes. Turning the tables, I ask how the dispositionalists themselves can deal with antidotes. The result will be to show that if the dispositionalists are to demystify antidote cases, they must make plausible a conceptualisation of dispositions that does not invoke any kind of necessity. I will cautiously suggest that the anti-Humean link dispositions bring to the world has to be thought of in terms of (Newtonian) forces. (shrink)

We investigate peer influence on managerial honesty under varying levels of transparency. In a laboratory experiment, managers report their costs to a superior to request budget. We manipulate whether the managers learn each other’s report and cost or the report but not the cost. The results show, first, that managers are susceptible to peer influence, as they join peers in reporting honestly and dishonestly both under full and partial transparency. Second, however, the effect of peer influence is asymmetric. While managers’ (...) dishonesty increases much when peers’ reports are higher than they have expected, the opposite is not true. Third, partial transparency reinforces this asymmetry in peer influence. Unlike full transparency, it allows managers to substitute self-serving assumptions for missing information and to thus justify their own dishonesty more easily. The contribution of this study is twofold: It provides evidence for the interaction between transparency and peer influence and it highlights the role of expectations in fueling dishonesty. Our findings warn firms that especially partial transparency may spread dishonesty more than honesty. Transparency may also hurt firms that push honesty norms but fail to enforce compliance, thus raising and disappointing managers’ expectations. (shrink)

In an important and widely discussed series of studies, Jonathan Phillips and colleagues have suggested that the ordinary concept of happiness has a substantial moral component. For in- stance, two persons who enjoy the same extent of positive emotions and are equally satisfied with their lives are judged as happy to different degrees if one is less moral than the other. Considering that the relation between morality and happiness or self-interest has been one of the central questions of moral philosophy (...) since at least Plato, such a result would be of considerable philosophical interest. On closer examination of the original research and new studies, we suggest that the data point to a different conclusion: in the dominant folk understanding of happiness, morality has no fundamental role. Findings seeming to indicate a moralized concept are better explained, we suggest, by folk theories on which extreme moral turpitude indicates that an individual suffers from psychological dysfunction.

This article introduces an “ordonomic” approach to corporate citizenship. We believe that ordonomics offers a conceptual framework for analyzing both the social structure and the semantics of moral commitments. We claim that such an analysis can provide theoretical guidance for the changing role of business in society, especially in regard to the expectation and trend that businesses take a political role and act as corporate citizens. The systematicraison d'êtreof corporate citizenship is that business firms can and—judged by the criterion of (...) prudent self-interest—“should” take on an active role in rule-finding discourses and rule-setting processes with the intent of realizing a win-win outcome of the economic game. We identify—and illustrate—four ways that corporate citizens can employ moral commitments as a factor of production to enhance their processes of economic value creation. (shrink)

In his ambitious Schelling's Late Philosophy in Confrontation with Hegel, Peter Dews sets out to reconstruct the fundamental difference between Schelling and Hegel on the basis of two related claims. The first, historical claim is that both are dealing with ‘our current historical situation’, which Dews identifies with ‘modernity’ (Dews 2023: 10). The second, systematic claim is that their mature systematic thinking is characterized by what he calls throughout the book, with reference to a canonical paper by Dieter Henrich (Henrich (...) 1976), their respective Grundoperationen (‘basic operations’). He then walks the reader through major positions that Schelling developed over the course of his philosophical career in order to demonstrate how Schelling arrives at a specific genealogical account of modernity. On this account, modernity is understood as a formation of consciousness, which is supposedly not subject to the Hegelian type of dialectic which, according to Dews, is driven by a rationalism so comprehensive that the very notion of unwarranted constraints on the agency of human beings or of the oppressive shaping of their consciousness has no place. (Dews 2023: 16). (shrink)

This article applies the tools of experimental philosophy to the ongoing debate about both the theoretical viability and the practical import of partially aggregative moral theories in distributive ethics. We conduct a series of three experiments (N=383): First, we document the widespread occurrence of the intuitions that motivate this position. Our study then moves beyond establishing the existence of partially aggregative intuitions in two dimensions: First, we extend experimental work in such a way as to ascertain which amongst existing versions (...) of partial aggregation (localised vs. global) chimes more fully with moral common sense. Specifically, we document how, in tie-breaking cases, ‘irrelevant goods’ judgments (Kamm) are just as robust as the original aggregative/non-aggregative pair of judgments that constitute partial aggregation. Second, by pairing laypeople’s moral judgments in standard cases with their intuitions about the limits of permissible self-prioritisation, we investigate whether one prominent explanation of why irrelevant claims may not be aggregated (Voorhoeve’s ‘personal prerogative’ argument) can be said to underpin people’s intuitions about the (ir)relevance relation of claims in conflict cases. We close with a discussion of our findings’ practical and theoretical import and highlight avenues for future research. (shrink)

Text-generative AI-systems have become important semantic agents with ChatGPT. We conducted a series of experiments to learn what teachers’ conceptions of text-generative AI are in relation to philosophical texts. In our main experiment, using mixed methods, we had twenty-four high school students write philosophical essays, which we then randomized to essays with the same command from ChatGPT. We had ten prospective teachers assess these essays. They were able to tell whether it was an AI or student essay with 78.7 percent (...) accuracy, which is better than the Open AI Classifier. Interestingly, however, they used criteria like argumentative and logical flawlessness and neutrality. We concluded from this that they are using an inverted Turing test and are no longer looking for rationality in machines but for irrationality in humans. (shrink)

The concept of a good life is usually assumed by philosophers to be equivalent to that of well-being, or perhaps of a morally good life, and hence has received little attention as a potentially distinct subject matter. In a series of experiments participants were presented with vignettes involving socially sanctioned wrongdoing toward outgroup members. Findings indicated that, for a large majority, judgments of bad character strongly reduce ascriptions of the good life, while having no impact at all on ascriptions of (...) happiness or well-being. Taken together with earlier findings these results suggest that the lay concept of a good life is clearly distinct from those of happiness, well-being, or morality , likely encompassing both morality and well-being, and perhaps other values as well: whatever matters in a person’s life. Importantly, morality appears not to play a fundamental role in either happiness or well-being among the folk. (shrink)

Intellectual humility is an interesting but underexplored disposition. The claim “I am (intellectually) humble” seems paradoxical in that someone who has the disposition in question would not typically volunteer it. There is an explanatory gap between the meaning of the sentence and the meaning the speaker expresses by uttering it. We therefore suggest analyzing intellectual humility semantically, using a psycholexical approach that focuses on both synonyms and antonyms of ‘intellectual humility’. We present a thesaurus-based method to map the semantic space (...) of intellectual humility as a heuristic to support philosophical and psychological analysis of this disposition. We find three semantic clusters that compose intellectual humility: the sensible self, the discreet self, and the inquisitive self; likewise, we find three clusters that compose its contraries: the overrated self, the underrated other, and the underrated self.

Like all causal theories in philosophy, the causal theory of action is plagued by the problem of deviant causal chains. I have proposed a solution on the basis of the assumption that mental states and events are causally efficacious in virtue of their contents. This solution has been questioned by Torbjörn Tännsjö (2009). First, I will reply to the objection, and then I will discuss Tännsjö’s alternative.

In this book, Michael Arbib, a researcher in artificial intelligence and brain theory, joins forces with Mary Hesse, a philosopher of science, to present an integrated account of how humans 'construct' reality through interaction with the social and physical world around them. The book is a major expansion of the Gifford Lectures delivered by the authors at the University of Edinburgh in the autumn of 1983. The authors reconcile a theory of the individual's construction of reality as a network of (...) schemas 'in the head' with an account of the social construction of language, science, ideology and religion to provide an integrated schema-theoretic view of human knowledge. The authors still find scope for lively debate, particularly in their discussion of free will and of the reality of God. The book integrates an accessible exposition of background information with a cumulative marshalling of evidence to address fundamental questions concerning human action in the world and the nature of ultimate reality.

Are our beliefs justified only relatively to a specific culture or society? Is it possible to give reasons for the superiority of our scientific, epistemic methods? Markus Seidel sets out to answer these questions in his critique of epistemic relativism. Focusing on the work of the most prominent, explicitly relativist position in the sociology of scientific knowledge – so-called 'Edinburgh relativism' or the 'Strong Programme' –, he scrutinizes the key arguments for epistemic relativism from a philosophical perspective: underdetermination and (...) norm-circularity. His main negative result is that these arguments fall short of establishing epistemic relativism. -/- Despite arguing for epistemic absolutism, Seidel aims to provide an account of non-relative justification that nevertheless integrates the basic, correct intuition of the epistemic relativist. His main positive result is that the epistemic absolutist can very well accept the idea that people using different standards of justification can be equally justified in holding their beliefs: Rational disagreement, he maintains, is perfectly possible. -/- The book provides a detailed critique of relativism in the sociology of scientific knowledge and beyond. With its constructive part it aims at making conciliatory steps in a highly embittered discussion between sociology and philosophy of science. (shrink)

Recently, a number of people have argued that certain entities embodied by groups of agents themselves qualify as agents, with their own beliefs, desires, and intentions; even, some claim, as moral agents. However, others have independently argued that fully-fledged moral agency involves a capacity for reactive attitudes such as guilt and indignation, and these capacities might seem beyond the ken of “collective” or “ corporate ” agents. Individuals embodying such agents can of course be ashamed, proud, or indignant about what (...) the agent has done. But just as an entity needs to have its own beliefs, desires, and intentions to qualify as a bona fide agent, the required capacity for reactive attitudes is a capacity to have one’s own reactive attitudes. If fully-fledged moral agency requires reactive attitudes, the corporate agent must itself be capable of guilt and indignation. In this paper, we argue that at least certain corporate agents are. Or, more precisely, we argue that if there are bona fide corporate agents, these agents can have the capacities that are both associated with guilt and indignation and plausibly required for moral agency; in particular certain epistemic and motivational capacities.

Previous research in Explainable Artificial Intelligence (XAI) suggests that a main aim of explainability approaches is to satisfy specific interests, goals, expectations, needs, and demands regarding artificial systems (we call these “stakeholders' desiderata”) in a variety of contexts. However, the literature on XAI is vast, spreads out across multiple largely disconnected disciplines, and it often remains unclear how explainability approaches are supposed to achieve the goal of satisfying stakeholders' desiderata. This paper discusses the main classes of stakeholders calling for explainability (...) of artificial systems and reviews their desiderata. We provide a model that explicitly spells out the main concepts and relations necessary to consider and investigate when evaluating, adjusting, choosing, and developing explainability approaches that aim to satisfy stakeholders' desiderata. This model can serve researchers from the variety of different disciplines involved in XAI as a common ground. It emphasizes where there is interdisciplinary potential in the evaluation and the development of explainability approaches. (shrink)

The levels of selection debate is generally taken to be a debate about how natural selection can occur at the various levels of biological organization. In this paper, we argue that questions about levels of selection should be analyzed separately from questions about levels of organization. In the deflationary proposal we defend, all that is necessary for multilevel selection is that there are cases in which particles are nested in collectives, and that both the collectives and the particles that compose (...) them each separately undergo natural selection. We argue that adopting this deflationary account helps to disentangle the levels of selection and the levels of organization, and thereby contributes to advancing the levels of selection debate.

Nurse philosopher Sally Gadow (1999) has proposed the relational narrative between patient and nurse as a ‘postmodern turn’ for nursing ethics. She has conceptualized this moral approach as the construction by patient and nurse of a coauthored narrative describing the good they are seeking, as well as the means to achieve this good. The purpose of this article is to provide an elaboration of Gadow's seminal conceptualization of relational narrative based on her writings and those of other philosophers. The article (...) will further develop relational narrative's foundations in relationship and narrative and will explore engagement as a dimension essential to its creation and growth. The elaboration first builds on the notion of relationship as foundational to this postmodern moral perspective. Narrative then is advanced as being at the heart of the patient–nurse relationship and their relational narrative, based on an exploration of narrative's role in the moral realm as an epistemology for patient and nurse. Finally, the dialogic and embodied engagement expressed by a relational narrative is developed as a critical element of the ethic. (shrink)

In Western thinking, the tradition of the argument for the existence of God beganwith Plato and Aristotle. It was carried forward in medieval scholasticism,eminently in Aquinas‟s so-called quinque viae, and reached its peak in modernphilosophy.

Arithmetic is one of the foundations of our educational systems, but what exactly is it? Numbers are everywhere in our modern societies, but what is our knowledge of numbers really about? This book provides a philosophical account of arithmetical knowledge that is based on the state-of-the-art empirical studies of numerical cognition. It explains how humans have developed arithmetic from humble origins to its modern status as an almost universally possessed knowledge and skill. Central to the account is the realisation that, (...) while arithmetic is a human creation, the development of arithmetic is constrained by our evolutionarily developed cognitive architecture. Arithmetic is a sophisticated cultural development, but it is ultimately based on abilities with numerosities that we already possess as infants and share with many non-human animals. Therefore, arithmetic is not purely conventional, an arbitrary game akin to chess. Instead, arithmetic is deeply connected to our basic cognitive capacities. (shrink)
