In the standard formulation of game theory, agents use mixed strategies in the form of objective and probabilistically precise devices to conceal their actions. We introduce the larger set of probabilistically imprecise devices and study the consequences for the basic results on normal form games. While Nash equilibria remain equilibria in the extended game, there arise new Ellsberg equilibria with distinct outcomes, as we illustrate by negotiation games with three players. We characterize Ellsberg equilibria in two-person conflict and coordination games. (...) These equilibria turn out to be related to experimental deviations from Nash equilibrium play. (shrink)

It is an assumption common to many theories of rationality that all practical reasons are based on a person's given desires. I shall call any approach to practical reasons which accepts this assumption a "Humean approach". In spite of many criticisms, the Humean approach has numerous followers who take it to be the natural and inevitable view of practical reason. I will develop an argument against the Humean view aiming to explain its appeal, as well as to expose its mistake. (...) I focus on just one argument in favour of the Humean approach, which I believe can be constructed as the background idea of many Humean accounts: the argument from motivation. (shrink)

In this paper I offer critical attention to the notion of atmosphere in relation to music. By exploring the concept through the case study of the Closed Brethren worship services, I argue that atmosphere may provide analytical tools to explore the ineffable in ecclesial practices. Music, just as atmosphere, commonly occupies a realm of ineffability and undermines notions such as inside and outside, subject and object. For this reason I present music as a means of knowing the atmosphere. The first (...) part of this paper points to the limits of an understanding of atmosphere as a constellation of things, as proposed by Gernot Böhme. In contrast to this, Hermann Schmitz conceptualises atmosphere as half-thing which suggests movement. Drawing on this, I propose to methodologically approach atmospheres as movements. Consequently, in the second part of this paper I closely analyse two motions as they cohere in Closed Brethren worship services: first, becoming (Deleuze and Guattari), a movement on the level of the individual worshiper; secondly, territorialisation (Deleuze and Guattari), a movement of the atmosphere towards its solidification. Here music as atmosphere is not a system of moral signification but a generative power affording intimate processes of divine encounter, whilst producing affective denominational difference.

This paper investigates the dynamic and performative construction of publics in public engagement exercises. In this investigation, we, on the one hand, analyse how public engagement settings as political machineries frame particular kinds of roles and identities for the participating publics in relation to ‘the public at large’. On the other hand, we study how the participating citizens appropriate, resist and transform these roles and identities, and how they construct themselves and the participating group in relation to wider publics. The (...) empirical basis of our argument is a discussion of four different kinds of participation events in Austria. Building on these observations we develop conclusions about the public up-take of public participation in technoscience and the role of public engagement in current techno-political cultures.

In this paper, I argue that a person can have a reason to do what she cannot do. In a nutshell, the argument is that a person can have derivate reasons relating to an action that she has a non-derivative reason to perform. There are clear examples of derivative reasons that a person has in cases where she cannot do what she (non-derivatively) has reason to do. She couldn’t have those derivative reasons, unless she also had the non-derivative reason to (...) do what she cannot do. I discuss a number of objections to this view, in particular two: (1) The objection that if there were reasons to do what one cannot do, many of those would be ‘crazy reasons’, and (2) the worry that if there were such reasons, then agents would have reasons to engage in futile deliberations and tryings. I develop an explanation of ‘crazy reasons’ that shows that not all reasons to do the impossible are crazy and only those that are need to be filtered out, and, regarding the second objecting, I show that the reasons for trying as well as for taking the means to doing something—instrumental reasons in a broad sense—are different from the reasons for performing the action in the first place. They are affected by impossibility, and we can explain why that is so. The view I argue for is that a person may have a reason to do what she cannot do, but she does not have a reason to try to do so or to take means to realizing the impossible. (shrink)

Luck, Value, and Commitment comprises eleven new essays which engage with, or take their point of departure from, the influential work in moral and political philosophy of Bernard Williams (1929-2003).

In this essay I examine the debate between Jürgen Habermas and Charles Taylor on the post-secular state. I argue that, although their views on the relation of religion and politics converge in certain respects, a profound difference remains between their overall approaches. Their disagreement on the epistemic status of religious as opposed to secular moral reasons, and on the role religious arguments can play in the public sphere testify to a deeper schism. Thus what might at first seem like a (...) quarrel about details proves to be a fundamental philosophical divide on the issue of modernity. I conclude that Taylor’s model of post-secularism is more promising as an approach to the challenge posed by growing religious and cultural diversity, for, if understood as a version of “reiterative universalism,” it avoids both moral relativism and Eurocentrism.

Possible measures to mitigate climate change require global collective actions whose impacts will be felt by many, if not all. Implementing such actions requires successful communication of the reasons for them, and hence the underlying climate science, to a degree that far exceeds typical scientific issues which do not require large-scale societal response. Empirical studies have identified factors, such as the perceived level of consensus in scientific opinion and the perceived reliability of scientists, that can limit people's trust in science (...) communicators and their subsequent acceptance of climate change claims. Little consideration has been given, however, to recent formal results within philosophy concerning the relationship between truth, the reliability of evidence sources, the coherence of multiple pieces of evidence/testimonies, and the impact of independence between sources of evidence. This study draws on these results to evaluate exactly what has been established in the empirical literature about the factors that bias the public's reception of scientific communications about climate change.

It has become common to distinguish between two kinds of ethical concepts: thick and thin ones. Bernard Williams, who coined the terms, explains that thick concepts such as “coward, lie, brutality, gratitude and so forth” are marked by having greater empirical content than thin ones. They are both action-guiding and world-guided: -/- If a concept of this kind applies, this often provides someone with a reason for action… At the same time, their application is guided by the world. A concept (...) of this sort may be rightly or wrongly applied, and people who have acquired it can agree that it applies or fails to apply to some new situation. -/- Thin concepts are concepts such as good and bad, right and wrong, obligation and duty. Judgments applying thick concepts have been seen as lending support to the possibility of explaining moral knowledge, and objectivity in ethics. It appears that due to their empirical content – their world-guidedness – judgments employing thick concepts can be true or false, depending on whether they get the worldly facts right. In addition they provide reasons for action – they are action-guiding – and thus may provide the starting point of a realist account of practical reasons: the view that reasons are facts and whether or not a person has a reason to act does not (normally) depend on her attitudes. The cruelty of an action is a reason not to perform it or to prevent it; that an action is kind is a reason in its favour. Of course these remarks aren’t conclusive – far from it. But even so, some non-cognitivists may regard them as completely wrongheaded, and so does Bernard Williams even though he is not a non-cognitivist. However, he believes that having a practical reason does depend on a person’s attitudes and motives. A certain worry about thick concepts will make clear what the problem is. It has most expressly been raised by Simon Blackburn, who sees it as undermining even the most superficial plausibility of moral cognitivism, as well as the claim that the properties picked out by thick concepts provide reasons. While we may readily accept that the kindness of an action or the fact that it is required by justice is a reason to perform it, there are many thick concepts whose action-guiding role we would reject. Some derogatory – e.g., racist or sexist - words express thick concepts too, Blackburn notes. And surely there are no racist or sexist truths. Furthermore there are concepts that some people use evaluatively (like chaste or obscene), but many of us do not regard the propositions in which those concepts feature as even prima facie reason giving. In raising these points, Blackburn claims that it is morally objectionable to regard the facts asserted in propositions which employ thick concepts as action-guiding because it leads to “a conservative and ultimately self-serving complacency.” As he sees it, the problem is that if we believe that the correct application of thick concepts yields evaluative truths and that evaluative truths state reasons for actions, we seem to be committed to accepting that some people are, say, fat, derog., and therefore to be ridiculed, and that there is at least a pro tanto reason to lead a chaste life, or feel affection towards cute women. Therefore, the view that all evaluative properties provide reasons for action or for attitudes such as admiration, affection or (dis)approval must be rejected. I will call this worry henceforth Blackburn’s challenge. The challenge is that understanding judgments employing thick concepts as expressing evaluative truths and providing reasons for actions or for attitudes leads to a morally unacceptable view. Blackburn suggests instead that we should separate the conditions for applying thick concepts and the reasons that we have in virtue of the concept applying. She may be cute, yes, but that is not a reason for “admiration and arousal.” -/- …it is morally vital that we proceed by splitting the input from the output in such a case. By refusing to split we fail to open an essential specifically normative dimension of criticism. -/- According to Blackburn, the meaning of thick concepts is made up of two distinct and in principle separable components: a descriptive one and the expression of an attitude. The truth-aptness and cognitive appearance of judgments employing thick concepts is explained by the descriptive component alone. Blackburn writes “[w]e get nothing but detachable and flexible attitudes, coupled with delineations of traits of character or action”. I will call this reply to Blackburn’s challenge the separability thesis. I agree with Blackburn that any account of thick concepts has to face and answer the challenge that he poses. In this paper, I will focus on one reply to the challenge which denies separability, namely Bernard Williams’s. Williams answers Blackburn’s challenge, while holding on to a cognitivist understanding of thick concepts. But his particular brand of cognitivism is peculiar: Williams rejects the separability thesis, and claims that correct applications of thick concepts yield evaluative (and not just descriptive) knowledge. But this is a special kind of knowledge. It is confined to a local community. The members of a community which uses certain thick concepts may have reasons to act accordingly, but the non-members do not. And even the reasons of members remain a little fragile: they may not want to continue using their concepts upon thorough reflection. The local knowledge view allows Williams to answer Blackburn’s challenge, because even though thick concepts are evaluative concepts and their application can yield evaluative knowledge, no one who isn’t a member of the relevant community has reason to be guided by the concept. Complementing a cognitivist view of thick concepts with reasons internalism allows Williams to answer the challenge. My aim in this paper is to show that Williams’s position is, despite its initial attraction, untenable. In particular, I am going to show why the internal reasons view is incompatible with Williams’s own understanding of thick concepts. My modest result is that the internalist view of reasons does not help to answer Blackburn’s challenge. My aim in this paper is not to answer the challenge but, rather, to explore the possibility of developing Williams’s attenuated version of cognitivism, and the possibility of combining it with reasons internalism.

It appears to be a feature of our ordinary understanding of morality that we ought not to act in certain ways at all. We ought not to kill, torture, deceive, break our promises (say)—exceptional circumstances apart. Many moral duties are thought of in this way. Killing another person would be wrong even if it achieved a great good, and even if it led to preventing the deaths of several others. This feature of moral thinking is at the core of deontological (...) ethics. But while it is also part and parcel of ordinary moral thought, it seems puzzling, because it requires an agent to act (or to abstain from acting) in certain ways, even if by violating the duty she could achieve a better outcome in terms of the very restriction that she is required to heed. If the explanation of the duty not to kill were that it preserves human life it would be hard to understand why killing is not morally permitted when it leads to preserving a greater number of lives. Moreover, why should we not violate a restriction if doing so leads to fewer violations of that very restriction? There are two questions here. (1) Why not violate a restriction whose point it is to preserve lives, if doing so leads to preserving a greater number of lives? (2) Why not violate a restriction if doing so minimizes the violation of that very restriction? The latter question concerns what is sometimes called ‘the paradox of deontology’ or the problem of ‘minimizing violations’. The former may concern the so-called trolley cases, for instance. After all, a trolley hurtling towards a number of innocent people is not about to violate the moral restriction on killing innocent people, as it is not the kind of thing that can be subject to such a restriction. In this paper I am concerned only with (2): the paradox of deontology. To put it in Nozick’s terms: ‘How can a concern for the nonviolation of C [i.e. some deontological constraint] lead to refusal to violate C even when this would prevent other more extensive violations of C? -/- Samuel Scheffler, puzzled by the same idea, put it in terms of ‘agent-centred restrictions’ (ACR), because the restriction requires an agent (not) to act in certain ways, contrasting thereby with a requirement that certain actions not be done. The restriction is thus an agent-relative rather than an agent-neutral one. Scheffler ended up rejecting the idea of agent-centred restrictions, as even on close investigation the puzzle would not dissolve. Scheffler maintains that ACRs have ‘an air of paradox’ to them, as they violate what he calls maximizing rationality. ACRs appear to clash with the idea of maximizing rationality, because they require an agent to choose the option that worse achieves her goal of not harming people. I call this, following common parlance, the paradox of deontology, even though it is not strictly speaking a paradox. Exploring whether there is really a problem here, and how it might be solved, is the main objective of this paper. I begin by explaining the puzzlement about agent-centred restrictions in more detail. I then discuss promising as an example of a kind of action which is thought to be subject to agent-centred restrictions. It turns out that they are surprisingly easy to explain. The difficult case is killing—and that should put us on guard. I argue that the problem is not with the very idea of deontological restrictions, but with puzzling aspects of the ethics of killing.

The notion of “the burden of proof” plays an important role in real-world argumentation contexts, in particular in law. It has also been given a central role in normative accounts of argumentation, and has been used to explain a range of classic argumentation fallacies. We argue that in law the goal is to make practical decisions whereas in critical discussion the goal is frequently simply to increase or decrease degree of belief in a proposition. In the latter case, it is (...) not necessarily important whether that degree of belief exceeds a particular threshold (e.g., ‘reasonable doubt’). We explore the consequences of this distinction for the role that the “burden of proof” has played in argumentation and in theories of fallacy. (shrink)

The buck-passing account of values offers an explanation of the close relation of values and reasons for action: of why it is that the question whether something that is of value provides reasons is not ”open.” Being of value simply is, its defenders claim, a property that something has in virtue of its having other reason-providing properties. The generic idea of buck-passing is that the property of being good or being of value does not provide reasons. It is other properties (...) that do. There are, however, at least three versions of the account which differ in their understanding of those “other properties.” The first two versions both assume that non-normative properties provide reasons, the difference being that the second allows that normative properties also provide reasons. Both run into difficulties, which I explain, in trying to defend the claim that non-normative properties provide reasons for action. The third version of the buck-passing account which explains being of value in terms of more specific evaluative properties that are reason-providing remains unpersuasive as well. Once we understand the relation between general and specific properties as a difference in degree, there is no space for a reduction of the one kind of properties to the other. In section II I sketch an alternative account of the relation between reasons and values, which is based on a thesis that I call the Conceptual Link and the claim that values are not just co-extensive with reasons, but explain them.

That the extraordinary narrative experiment known as theSatyriconhas regularly stimulated scholarly investigation into the relationship between status and freedom is not surprising for a work, the longest surviving section of which features an excessive dinner party at the house of alibertus. Much of the discussion has concentrated on the depiction of the dinner's host and his freedmen friends. Following the lead of F. Zeitlin and others in seeing the depiction of a ‘freedmen's milieu’ in theCena, J. Bodel argued in a (...) seminal paper published twenty years ago that theCenaopens a window onto the ‘freedman's mentality’. The last ten years or so have seen a revival of the theme, with much emphasis on the display of an open society in theCena, even a Saturnalian world-view, based on a suspension or reversal of the traditional social hierarchies, all framed by a general air of excessive liberality: whatever satirical lens theSatyricon’s author is seen to have projected onto Trimalchio and his freedmen friends,theyare understood as celebrating ‘freedom's defining difference’. In the light of such a unifying conceptualization of theCena’s motley crew, it is not surprising that scholars have come to understand the libertine assemblage as a reflection of ‘the social class of the “freedmen” in first-centurya.d.Italy’. After all, ‘class’ can be defined as ‘a number of individuals (persons or things) possessing common attributes’, and, with specific regard to human society, as ‘a division of society according to status’.

Is the wrongness of an action a reason not to perform it? Of course it is, you may answer. That an action is wrong both explains and justifies not doing it. Yet, there are doubts. Thinking that wrongness is a reason is confused, so an argument by Jonathan Dancy. There can’t be such a reason if ‘ϕ-ing is wrong’ is verdictive, and an all things considered judgment about what (not) to do in a certain situation. Such judgments are based on (...) all the relevant reasons for and against ϕ-ing. If that ϕ-ing is wrong, while being an all things considered verdict, would itself be a reason, it would upset the balance of reasons: it would be a further reason which has not yet been considered in reaching the verdict. Hence, the judgment wasn’t ‘all things considered' after all. I show that the argument against wrongness being a reason is unsuccessful, because its main assumption is false. Is main assumption is that a consideration which necessarily does not affect the balance of reasons is not a reason. I also argue that there can be no deontic buck-passing account. (shrink)

In this article, we argue for the general importance of normative theories of argument strength. We also provide some evidence based on our recent work on the fallacies as to why Bayesian probability might, in fact, be able to supply such an account. In the remainder of the article we discuss the general characteristics that make a specifically Bayesian approach desirable, and critically evaluate putative flaws of Bayesian probability that have been raised in the argumentation literature.

The buck-passing account of value (BPA) is very fertile ground that has given rise to a number of interpretations and controversies. It has originally been proposed by T.M. Scanlon as an analysis of value: according to it, being good ‘is not a property that itself provides a reason to respond to a thing in certain ways. Rather, to be good or valuable is to have other properties that constitute such reasons’. Buck-passing stands in a complicated relation to the fitting-attitude analysis (...) of normativity that reaches back to the work of Brentano and Ewing. Proponents of FA-analysis hold that, as a matter of the conceptual analysis of ‘good’, something is good if it is fitting to have pro-attitudes of a certain kind towards it. The ambition of FA-analysis is to explain all practical normativity in terms of the fittingness of attitudes, which – while being itself a normative concept – is the only normative concept which grounds all others. Wlodek Rabinowicz and Toni Rønnow-Rasmussen welcomed BPA as a contemporary version of FA-analysis, and others have followed this suggestion. But whether BPA should be regarded as a version of FA-analysis is a moot point. In section I, I show that BPA is not as obviously a successor of the fitting-attitude analysis of value as some have thought. The much discussed wrong-kind-of-reasons (for short: WKR) problem afflicts buck-passing only in so far as it incorporates a version of FA analysis, or at any rate is expressed in terms of reasons for attitudes. There can be a buck-passing account of value which is not affected by the problem: one that limits the account to reasons for actions (rather than attitudes). However, insofar as BPA does inherit elements of FA analysis, it also has a WKR problem. In section II, I discuss this problem and its solution. I show that it has been misidentified in the current literature, and that – once we understand the problem correctly – its solution is likely to be unavailable to the buck-passer. Hence we should reject any account of BPA that incorporates FA analysis. That leaves us with versions which do not: versions that formulate BPA in terms of reasons for actions only, rather than reasons for attitudes. Finally, in section III, I discuss why buck-passing seemed to be appealing to begin with, and whether a version of BPA that does not incorporate FA analysis is a viable contender of the account – beyond the WKR problem.

This paper argues that, contrary to a common line of criticism followed by scholars such as Helga Kuhse, a particularistic version of virtue ethics properly elaborated, can provide sound moral guidance and a satisfactory account for moral justification of our opinions regarding, for instance, health care practice. In the first part of the paper, three criteria for comparing normative theories with respect to action‐guiding power are outlined, and it is argued that the presented particularistic version of virtue ethics actually can (...) provide more guidance than the universalistic theories favoured by Kuhse and others. In the second part of the paper it is claimed that universalist normative theories have serious problems accounting for the role that moral principles are supposed to play in the justification, of moral opinions, whereas the present version of virtue ethics accommodates a plausible alternative idea of justification without invoking moral principles or eschewing objectivity.

Background: Recent research has demonstrated that depressed individuals show impairments in inhibiting irrelevant emotional material, and that these impairments are linked to rumination. Cognitive inhibition, however, is not a unitary construct but consists of several components which operate at different stages of information processing. The present study was designed to assess two components of inhibition and examine their relation to depression and rumination in a sample of clinically depressed and healthy control participants. Methods: Twenty-two individuals diagnosed with a current depressive (...) episode and 27 never-disordered control participants completed an Emotional Flanker Task to assess individual differences in interference control and a modification of the Working Memory Selection Task to assess individual differences in the ability to discard no longer relevant emotional material from working memory. Participants completed self-report measures to assess depressive symptoms and rumination. Results: Clinically depressed compared to control participants showed significantly reduced interference control of irrelevant negative information. The groups, however, did not differ in their ability to discard no longer relevant negative information from working memory. In contrast, rumination was associated with difficulty removing no longer relevant negative material from working memory but not with deficits in interference control. Conclusions: Results highlight the importance of differentiating among components of inhibition to gain a better understanding of cognitive mechanisms underlying depression and rumination. (shrink)

Many of the things we do in the course of a day we don't do intentionally: blushing, sneezing, breathing, blinking, smiling—to name but a few. But we also do act intentionally, and often when we do we act for reasons. Whether we always act for reasons when we act intentionally is controversial. But at least the converse is generally accepted: when we act for reasons we always act intentionally. Necessarily, it seems. In this paper, I argue that acting intentionally is (...) not in all cases acting for a reason. Instead, intentional agency involves a specific kind of control. Having this kind of control makes it possible to modify one's action in the light of reasons. Intentional agency opens the possibility of acting in the light of reasons. I also explain why when we act with an intention we act for reasons. In the second part of the paper, I draw on these results to show that the dominant view of reasons to intend and the rationality of intentions should be rejected. (shrink)

Bei Kant tauchen viele antike Autoren und Theorien auf. In dieser ersten Gesamtbearbeitung zum Thema wird gegen eine langjährige Forschungsmeinung gezeigt, dass nicht so sehr Platon und Aristoteles als vielmehr der hellenistischen Philosophie die entscheidende Rolle für sein Denken zukommt.

The requirement of informed consent (IC) to medical treatments is almost invariably justified with appeal to patient autonomy. Indeed, it is common to assume that there is a conceptual link between the principle of respect for autonomy and the requirement of IC, as in the influential work of Beauchamp and Childress. In this paper I will argue that the possible relation between the norm of respecting (or promoting) patient autonomy and IC is much weaker than conventionally conceived. One consequence of (...) this is that it is possible to exercise your autonomy without having the amount of and the kind of information that are assumed in the standard requirement of IC to medical treatments. In particular, I will argue that with a plausible conception of patient autonomy, the respect for and the promotion of patient autonomy are in certain circumstances better protected by giving patients the right to give their negatively informed consent to medical treatments.

Modern society makes extensive use of automated algorithmic decisions, fueled by advances in artificial intelligence. However, since these systems are not perfect, questions about fairness are increasingly investigated in the literature. In particular, many authors take a Rawlsian approach to algorithmic fairness. This article aims to identify some complications with this approach: Under which circumstances can Rawls’s original position reasonably be applied to algorithmic fairness decisions? First, it is argued that there are important differences between Rawls’s original position and a (...) parallel algorithmic fairness original position with respect to risk attitudes. Second, it is argued that the application of Rawls’s original position to algorithmic fairness faces a boundary problem in defining relevant stakeholders. Third, it is observed that the definition of the least advantaged, necessary for applying the difference principle, requires some attention in the context of algorithmic fairness. Finally, it is argued that appropriate deliberation in algorithmic fairness contexts often require more knowledge about probabilities than the Rawlsian original position allows. Provided that these complications are duly considered, the thought-experiment of the Rawlsian original position can be useful in algorithmic fairness decisions. (shrink)

Explaining the relation of values and reasons is a major focus of Joseph Raz’s work. I examine his account of the relation of values and reasons, focusing in particular on practical reasons. As a preliminary way of delineating two basic alternatives for mapping the relation of values and reasons, let me pose the Euthyphro-style question: (1) Is something valuable because we have reasons to behave in some way with respect to it? Or: (2) Do we have reasons to behave in (...) some way with respect to it because it is valuable? Though helpful for contrasting different approaches, this question is still multiply ambiguous. It may be interpreted as a question concerning the metaphysical primacy of values and reasons respectively - that is, whether there have to be things of value for there to be reasons, or vice versa. There is also a question of conceptual primacy: Can ‘value’ be defined in terms of reasons, or can ‘reason’ be defined in terms of value? A related, but different question is epistemological: Does a person have to be able to master the concept of value in order to understand the concept of a reason (or, again, vice versa)? I use these three questions as guidelines for investigating Raz’s view of the relation of values and reasons. Are values (1) metaphysically, (2) conceptually, and/or (3) epistemologically prior to reasons? Or are reasons in all or any of these respects prior to value? My strategy in the paper is as follows: In section 1, I locate Raz’s position with respect to these three questions by contrasting his views with those of Thomas Scanlon. In section 2, I work out Raz’s account of reasons and values in some greater detail. And then, in section 3, I discuss what I take to be the remaining major problem with Raz’s approach. (shrink)
