According to an increasingly popular epistemological view, people need outright beliefs in addition to credences to simplify their reasoning. Outright beliefs simplify reasoning by allowing thinkers to ignore small error probabilities. What is outright believed can change between contexts. It has been claimed that thinkers manage shifts in their outright beliefs and credences across contexts by an updating procedure resembling conditionalization, which I call pseudo-conditionalization (PC). But conditionalization is notoriously complicated. The claim that thinkers manage their beliefs via PC is (...) thus in tension with the view that the function of beliefs is to simplify our reasoning. I propose to resolve this puzzle by rejecting the view that thinkers employ PC. Based on this solution, I furthermore argue for a descriptive and a normative claim. The descriptive claim is that the available strategies for managing beliefs and credences across contexts that are compatible with the simplifying function of outright beliefs can generate synchronic and diachronic incoherence in a thinker’s attitudes. Moreover, I argue that the view of outright belief as a simplifying heuristic is incompatible with the view that there are ideal norms of coherence or consistency governing outright beliefs that are too complicated for human thinkers to comply with.

This interpretive introduction provides unique insight into Plato's Republic. Stressing Plato's desire to stimulate philosophical thinking in his readers, Julia Annas here demonstrates the coherence of his main moral argument on the nature of justice, and expounds related concepts of education, human motivation, knowledge and understanding. In a clear systematic fashion, this book shows that modern moral philosophy still has much to learn from Plato's attempt to move the focus from questions of what acts the just person ought to (...) perform to the more profound questions of what sort of person the just person ought to be.

In this paper I am concerned with the question of whether degrees of belief can figure in reasoning processes that are executed by humans. It is generally accepted that outright beliefs and intentions can be part of reasoning processes, but the role of degrees of belief remains unclear. The literature on subjective Bayesianism, which seems to be the natural place to look for discussions of the role of degrees of belief in reasoning, does not address the question of whether degrees (...) of belief play a role in real agents’ reasoning processes. On the other hand, the philosophical literature on reasoning, which relies much less heavily on idealizing assumptions about reasoners than Bayesianism, is almost exclusively concerned with outright belief. One possible explanation for why no philosopher has yet developed an account of reasoning with degrees of belief is that reasoning with degrees of belief is not possible for humans. In this paper, I will consider three arguments for this claim. I will show why these arguments are flawed, and conclude that, at least as far as these arguments are concerned, it seems like there is no good reason why the topic of reasoning with degrees of belief has received so little attention.

The book provides a commentary on Plato's Republic which encourages the reader to be stimulated to philosophical thinking by Plato's wide-ranging discussions.

Epistemic permissivism is the view that it is possible for two people to rationally hold incompatible attitudes toward some proposition on the basis of one body of evidence. In this paper, I defend a particular version of permissivism – unacknowledged permissivism (UP) – which says that permissivism is true, but that no one can ever rationally believe that she is in a permissive case. I show that counter to what virtually all authors who have discussed UP claim, UP is an (...) attractive view: it is compatible with the intuitive motivations for permissivism and avoids a significant challenge to permissivism: the arbitrariness objection.

Many philosophers hold that the probability axioms constitute norms of rationality governing degrees of belief. This view, known as subjective Bayesianism, has been widely criticized for being too idealized. It is claimed that the norms on degrees of belief postulated by subjective Bayesianism cannot be followed by human agents, and hence have no normative force for beings like us. This problem is especially pressing since the standard framework of subjective Bayesianism only allows us to distinguish between two kinds of credence (...) functions—coherent ones that obey the probability axioms perfectly, and incoherent ones that don’t. An attractive response to this problem is to extend the framework of subjective Bayesianism in such a way that we can measure differences between incoherent credence functions. This lets us explain how the Bayesian ideals can be approximated by humans. I argue that we should look for a measure that captures what I call the ‘overall degree of incoherence’ of a credence function. I then examine various incoherence measures that have been proposed in the literature, and evaluate whether they are suitable for measuring overall incoherence. The competitors are a qualitative measure that relies on finding coherent subsets of incoherent credence functions, a class of quantitative measures that measure incoherence in terms of normalized Dutch book loss, and a class of distance measures that determine the distance to the closest coherent credence function. I argue that one particular Dutch book measure and a corresponding distance measure are particularly well suited for capturing the overall degree of incoherence of a credence function. (shrink)

Epistemic utility theory seeks to establish epistemic norms by combining principles from decision theory and social choice theory with ways of determining the epistemic utility of agents’ attitudes. Recently, Moss, 1053–69, 2011) has applied this strategy to the problem of finding epistemic compromises between disagreeing agents. She shows that the norm “form compromises by maximizing average expected epistemic utility”, when applied to agents who share the same proper epistemic utility function, yields the result that agents must form compromises by splitting (...) the difference between their credence functions. However, this “split the difference” norm is in conflict with conditionalization, since applications of the two norms don’t commute. A common response in the literature seems to be to abandon the procedure of splitting the difference in favor of compromise strategies that avoid non-commutativity. This would also entail abandoning Moss’ norm. I explore whether a different response is feasible. If agents can use epistemic utility-based considerations to agree on an order in which they will apply the two norms, they might be able to avoid diachronic incoherence. I show that this response can’t save Moss’ norm, because the agreements concerning the order of compromising and updating it generates are not stable over time, and hence cannot avoid diachronic incoherence. I also show that a variant of Moss’ norm, which requires that the weights given to each agent’s epistemic utility change in a way that ensures commutativity, cannot be justified on epistemological grounds.

This paper proposes a novel answer to the question of what attitude agents should adopt when they receive misleading higher-order evidence that avoids the drawbacks of existing views. The answer builds on the independently motivated observation that there is a difference between attitudes that agents form as conclusions of their reasoning, called terminal attitudes, and attitudes that are formed in a transitional manner in the process of reasoning, called transitional attitudes. Terminal and transitional attitudes differ both in their descriptive and (...) in their normative properties. When an agent receives higher-order evidence that they might have reasoned incorrectly to a belief or credence towards p, then their attitude towards p is no longer justified as a terminal attitude towards p, but it can still be justified as a transitional attitude. This view, which I call the unmooring view, allows us to capture the rational impact of misleading higher-order evidence in a way that integrates smoothly with a natural picture of epistemic justification and the dynamics of deliberation.

Sorensen offers the following definition of a ‘knowledge-lie’: ‘An assertion that p is a knowledge-lie exactly if intended to prevent the addressee from knowing that p is untrue but is not intended to deceive the addressee into believing p.’ According to Sorensen, knowledge-lies are not meant to deceive their addressee, and this fact is supposed to make them less bad than ordinary lies. I will argue that standard cases of knowledge-lies, including almost all the cases Sorensen considers, do in fact (...) involve deception, contrary to what Sorensen claims. And while there are cases of non-deceptive knowledge-lies, such cases are deviant, either because it is only incidental that the knowledge-preventing assertion is a lie, or because it is only incidental that the lie doesn't deceive. Here's an example of a knowledge-lie: Dr Head is considering firing Dr Appendix because of his weak research. But he doesn't want to fire Appendix unless he knows that Appendix's research isn't good, and so he consults Dr Heart. Head knows that if Appendix's research is good, then Heart will tell the truth and say so, whereas if Appendix's work isn't good, then Heart may or may not …. (shrink)

It is sometimes argued that virtue ethics is incapable of 'telling us what to do'. I explore what this could mean, and come to the conclusion that virtue ethics does enable this, in the only sense in which it is something which we would reasonably want in an ethical theory.

Active reasoning is the kind of reasoning that we do deliberately and consciously. In characterizing the nature of active reasoning and the norms it should obey, the question arises which attitudes we can reason with. Many authors take outright beliefs to be the attitudes we reason with. Others assume that we can reason with both outright beliefs and degrees of belief. Some think that we reason only with degrees of belief. In this paper I approach the question of what kinds (...) of beliefs can participate in reasoning by using the following method: I take the default position to be maximally permissive – that both graded and outright beliefs can participate in reasoning. I then identify some features of active reasoning that appear at first glance to favor a more restrictive position about which types of belief we can reason with. I argue that the arguments based on these features ultimately fail. (shrink)

Ideal agents are role models whose perfection in some normative domain we try to approximate. But which form should this striving take? It is well known that following ideal rules of practical reasoning can have disastrous results for non-ideal agents. Yet, this issue has not been explored with respect to rules of theoretical reasoning. I show how we can extend Bayesian models of ideally rational agents in order to pose and answer the question of whether non-ideal agents should form new (...) degrees of belief in the same way as their ideal counterparts. I demonstrate that the epistemic and the practical case are parallel: following ideal rules does not always lead to optimal outcomes for non-ideal agents. (shrink)

In the literature on philosophical progress it is often assumed that agreement is a necessary condition for progress. This assumption is sensible only if agreement is a reliable sign of the truth, since agreement on false answers to philosophical questions would not constitute progress. This paper asks whether agreement among philosophers is (or would be) likely to be a reliable sign of truth. Insights from social choice theory are used to identify the conditions under which agreement among philosophers would be (...) a reliable indicator of the truth, and it is argued that we lack good reason to think that philosophical inquiry meets these conditions. The upshot is that philosophical agreement is epistemically uninformative: agreement on the answer to a philosophical question does not supply even a prima facie reason to think that the agreed-upon view is true. However, the epistemic uninformativeness of philosophical agreement is not an indictment of philosophy's progress, because philosophy is valuable independent of its ability to generate agreement on the correct answers to philosophical questions.

The human body can be regarded in at least two ways: objectively, as a physical and organic body; and subjectively, as the center of orientation and lived affective unity. However, this distinction can lose sight of the fact that the ‘lived body’ is not reducible to subjective idiosyncrasies. Trans-individual norms are embodied too, as Michel Foucault and Judith Butler have shown. Phenomenological investigations of normalization and habitualization help bring these two important dimensions of embodiment together and overcome simplistic oppositions between (...) phenomenological and poststructuralist approaches. These investigations lead into issues of female body optimization and control that we take to be characteristic of contemporary neoliberalist embodiment. (shrink)

The aim of this paper is to examine whether it would be advantageous to introduce knowledge norms instead of the currently assumed rational credence norms into the debate about decision making under normative uncertainty. There is reason to think that this could help us better accommodate cases in which agents are rationally highly confident in false moral views. I show how Moss’ view of probabilistic knowledge can be fruitfully employed to develop a decision theory that delivers plausible verdicts in these (...) cases. I also argue that, for this new view to be better than existing alternatives, it must adopt a particular solution to the new evil demon problem, which asks whether agents and their BIV-counterparts are equally justified. In order to get an attractive decision theory for cases of moral uncertainty, we must reject the claim that agents and their BIV-counterparts are equally justified. Moreover, the resulting view must be supplemented with a moral epistemology that explains how it is possible to be rationally morally uncertain. This is especially challenging if we assume that moral truths are knowable a priori. (shrink)

This book features new essays by philosophers, psychologists, and a theologian on the important topic of virtue development. The essays engage with work from multiple disciplines and thereby seek to bridge disciplinary divides. The volume is a significant contribution to the emerging interdisciplinary field of virtue development studies.

The concept of imagination is notoriously ambiguous. Thus one must be cautious not to use ‘imagination’ as a placeholder for diverse phenomena and processes that perhaps have not much more in common than that they are difficult to assign to some other, better defined domain, such as perception, conceptual thought, or artistic production. However, this challenge also comes with great opportunities: the fecundity and openness of ‘imagination’ appeal to researchers from different disciplines with different approaches and questions, and it draws (...) together fields of enquiry that are initially considered far apart. Hence, arguably, the field of imagination is particularly poised for interdisciplinary enquiry. In the section on Imagination in Interdisciplinary Research, I will talk about some of the issues that have already entered that field of interdisciplinary inquiry. (shrink)

In his new book "The Importance of Being Rational", Errol Lord aims to give a real definition of the property of rationality in terms of normative reasons. If he can do so, his work is an important step towards a defense of ‘reasons fundamentalism’ – the thesis that all complex normative properties can be analyzed in terms of normative reasons. I focus on his analysis of epistemic rationality, which says that your doxastic attitudes are rational just in case they are (...) correct responses to the objective normative reasons you possess. For some fact to be an objective normative reason to do something that you possess, you have to be in a position to know this fact and be able to competently use it as a reason to do that thing. Lord’s view is thus a knowledge-first view about possessing normative reasons. Throughout the book, Lord conceptualizes belief in the traditional tripartite way – if you take any attitude at all towards a proposition, then you either believe it, or disbelieve it, or you suspend judgment about it. Lord doesn’t discuss cases in which we’re uncertain. Yet, those cases are ubiquitous. I explore how his view can be extended to them. I first discuss whether his strategy for vindicating coherence requirements in terms of normative reasons can be applied to credences. I then ask how Lord can conceive of the doxastic attitudes that encode uncertainty . (shrink)

In this article, I discuss three distinct but related puzzles involving lotteries: Kyburg’s lottery paradox, the statistical evidence problem, and the Harman-Vogel paradox. Kyburg’s lottery paradox is the following well-known problem: if we identify rational outright belief with a rational credence above a threshold, we seem to be forced to admit either that one can have inconsistent rational beliefs, or that one cannot rationally believe anything one is not certain of. The statistical evidence problem arises from the observation that people (...) seem to resist forming outright beliefs whenever the available evidence for the claim under consideration is purely statistical. We need explanations of whether it is in fact irrational to form such beliefs, and of whether a clear distinction can be drawn between statistical and non-statistical evidence. The Harman-Vogel paradox is usually presented as a paradox about knowledge: we tend to assume that we can know so-called ordinary propositions, such as the claim that I will be in Barcelona next spring. Yet, we hesitate to make knowledge claims regarding so-called lottery propositions, such as the claim that I won’t die in a car crash in the next few months, even if these lottery propositions are obviously entailed by the ordinary propositions we claim to know. Depending on one’s view about the relationship between rational belief and knowledge, the Harman-Vogel paradox has ramifications for a theory of rational outright belief. Formal theories of the relationship between rational credence and rational belief, such as Leitgeb’s stability theory, tend to focus mostly on handling Kyburg’s lottery paradox, but not the other two puzzles I mention. My aim in this article is to draw out relationships and differences between the puzzles, and to examine to what extent existing formal solutions to Kyburg’s lottery paradox help with answering the statistical evidence problem and the Harman-Vogel paradox.

What attitudes can we rationally take towards our philosophical views? In this paper, I offer a novel answer to this question that draws on the distinction between transitional and terminal attitudes (Staffel 2019). Terminal attitudes are the kinds of attitudes, such as beliefs and credences, that we form as conclusions of reasoning processes. Transitional attitudes, by contrast, are attitudes we form during ongoing deliberations, before we settle on an opinion about how our information bears on the question of interest. I (...) argue that we can rationally hold terminal attitudes towards local philosophical claims, but not global ones. Only transitional attitudes can be rationally held towards global philosophical claims, at least in most cases. (shrink)

We argue that the evolutionary function of reasoning is to allow us to secure more accurate beliefs and more effective intentions through collective deliberation. This sets our view apart both from traditional intellectualist accounts, which take the evolutionary function to be individual deliberation, and from interactionist accounts such as the one proposed by Mercier and Sperber, which agrees that the function of reasoning is collective but holds that it aims to disseminate, rather than come up with, accurate beliefs. We argue (...) that our collectivized intellectualism offers the best explanation of the range of biases that human reasoning is prone to, and that it does better than interactionism at offering a function of reasoning that would have been adaptive for our distant ancestors who first evolved this capacity.

One of the best places to seek understanding of happiness is the study of ancient ethical theories and of those modern theories which share their eudaimonist concerns. For these recognize, and build on, some of our thoughts about happiness that have become overwhelmed by the kind of consideration that emerges in the claim that happiness is obviously subjective. Given the systematically disappointing results of the database approach, it is time to look seriously at our alternatives.

When examining the role of Stoic ethics within Stoic philosophy as a whole, it is useful for us to look at the Stoic view of the way in which philosophy is made up of parts. The aim is a synoptic and integrated understanding of the "theoremata" of all the parts, something which can be achieved in a variety of ways, either by subsequent integration of separate study of the three parts or by proceeding through 'mixed' presentations, which can be made (...) at varying levels of understanding. In two presentations of Stoic ethics we find initially baffling claims about the life of virtue being 'the same as' or 'equivalent to' the life according to nature. These indicate approaches in which understanding of ethical concepts was enlarged and enriched by study of physics. Interpretation which makes physics in these passages into ethical foundations answers poorly to the ancient texts and raises severe difficulties as an interpretation of Stoicism. Two texts which have been taken to commit Stoics to a foundationalist view of the relation of ethics and physics do not in fact do so; rather, they fit well into the holistic view of philosophy and its parts.

Special Issue, n. I, ch. 1, On the Transcendental.

This entry provides an overview of the current state of the debate between epistemic permissivists and impermissivists. Three important choice points for the permissivist are identified, and implications are discussed for plausibility of the resulting versions of permissivism.

Bayesian epistemology provides a popular and powerful framework for modeling rational norms on credences, including how rational agents should respond to evidence. The framework is built on the assumption that ideally rational agents have credences, or degrees of belief, that are representable by numbers that obey the axioms of probability. From there, further constraints are proposed regarding which credence assignments are rationally permissible, and how rational agents’ credences should change upon learning new evidence. While the details are hotly disputed, all (...) flavors of Bayesianism purport to give us norms of ideal rationality. This raises the question of how exactly these norms apply to you and me, since perfect compliance with those ideal norms is out of reach for human thinkers. A common response is that Bayesian norms are ideals that human reasoners are supposed to approximate – the closer they come to being ideally rational, the better. To make this claim plausible, we need to make it more precise. In what sense is it better to be closer to ideally rational, and what is an appropriate measure of such closeness? This article sketches some possible answers to these questions. (shrink)

Background: COVID-19 pandemic has led to heightened moral distress among healthcare providers. Despite evidence of gendered differences in experiences, there is limited feminist analysis of moral distress. Objectives: To identify types of moral distress among women healthcare providers during the COVID-19 pandemic; to explore how feminist political economy might be integrated into the study of moral distress. Research Design: This research draws on interviews and focus groups, the transcripts of which were analyzed using framework analysis. Research Participants and Context: 88 (...) healthcare providers, based in British Columbia Canada, participated virtually. Ethical Considerations: The study received ethical approval from Simon Fraser University. Findings: Healthcare providers experienced moral dilemmas related to ability to provide quality and compassionate care while maintaining COVID-19 protocols. Moral constraints were exacerbated by staffing shortages and lack of access to PPE. Moral conflicts emerged when women tried to engage decision-makers to improve care, and moral uncertainty resulted from lack of clear and consistent information. At home, women experienced moral constraints related to inability to support children’s education and wellbeing. Moral conflicts related to lack of flexible work environments and moral dilemmas developed between unpaid care responsibilities and COVID-19 risks. Women healthcare providers resisted moral residue and structural constraints by organizing for better working conditions, childcare, and access to PPE, engaging mental health support and drawing on professional pride. Discussion: COVID-19 has led to new and heightened experiences of moral distress among HCP in response to both paid and unpaid care work. While many of the experiences of moral distress at work were not explicitly gendered, implicit gender norms structured moral events. Women HCP had to take it upon themselves to organize, seek out resources, and resist moral residue. Conclusion: A feminist political economy lens illuminates how women healthcare providers faced and resisted a double layering of moral distress during the pandemic. (shrink)

Nature in the Politics has been most extensively studied in the context of the book 1 argument that the polis is "by nature." Fred Miller's Nature, Justice, and Rights in Aristotle's Politics is a landmark in this respect as in many others, and his discussion of the naturalness of the polis is, I think, definitive, and should put an end to the notion that according to Aristotle people find their natural end functioning as mere parts in some large organic social (...) whole. However, nature in Aristotle's ethical and political works contains complications outside book 1, and I hope that there remain some points to be made and issues to be elucidated. (shrink)

Until relatively recently, researchers believed that synaesthetic sensations and their triggers were arbitrarily paired, and entirely idiosyncratic from one synaesthete to the next. Put differently, they believed that no two synaesthetes would have similar experiences from the same set of triggers, unless this had occurred by chance. This position likely arose because, prior to the internet, it was extremely difficult to recruit more than a small handful of synaesthete participants, and on the surface, synaesthetes do tend to disagree on their (...) associations when compared one-on-one. However, recent advances in communication have allowed researchers access to far larger groups of synaesthete participants, and this has changed our opinion about how similar synaesthetes might in fact be. A dedicated body of research has now shown that synaesthetic associations are built, to some extent, on a set of unconscious 'rules', shared across synaesthetes. These rules dictate the choice of sensation for certain triggers, and allow us to see patterns emerging which, although not absolute, provide a type of coherence across synaesthetes as a whole. I shall also show that some of these underlying rules operate in the population at large, to allow all individuals to make intuitive pairings across the senses. This chapter describes some of these rules, across a range of different modalities, and across different variants of synaesthesia. (shrink)

The Routledge Companion to Performance Philosophy is a volume of especially commissioned critical essays, conversations, collaborative, creative and performative writing mapping the key contexts, debates, methods, discourses and practices in this developing field. Firstly, the collection offers new insights on the fundamental question of how thinking happens: where, when, how and by whom philosophy is performed. Secondly, it provides a plurality of new accounts of performance and performativity as the production of ideas, bodies and knowledges in the arts and beyond. (...) Comprising texts written by international artists, philosophers and scholars from multiple disciplines, the essays engage with questions of how performance thinks and how thought is performed in a wide range of philosophies and performances, from the ancient to the contemporary. Concepts and practices from diverse geographical regions and cultural traditions are analysed to draw conclusions about how performance operates across art, philosophy and everyday life. The collection both contributes to and critiques the philosophy of music, dance, theatre and performance, exploring the idea of a philosophy from the arts. It is crucial reading material for those interested in the hierarchy of the relationship between philosophy and the arts, advancing debates on philosophical method, and the relation between Performance and Philosophy more broadly.

This essay argues that Aristotle’s view of memory is more like that of the modern psychologist than that of a modern philosopher; he is more interested in accurately delineating different kinds of memory than in discussing philosophical problems of memory. The short treatise On Memory and Recollection is considered a treatise on memory and loosely associated phenomenon and recollection. It is suggested that this work is better regarded as a treatise on two kinds of memory.

Cicero is increasingly recognised as a highly intelligent contributor to the ongoing ethical debates between Epicureans, Stoics and other schools. In this work on the fundamentals of ethics his learning as a scholar, his skill as a lawyer and his own passion for the truth result in a work which dazzles us in its presentation of the debates and at the same time exhibits the detachment of the ancient sceptic.
