This is a revision of game theory which takes account of agents' own descriptions of their situations, and which allows people to reason as members of groups.

Payoff dominance, a criterion for choosing between equilibrium points in games, is intuitively compelling, especially in matching games and other games of common interests, but it has not been justified from standard game-theoretic rationality assumptions. A psychological explanation of it is offered in terms of a form of reasoning that we call the Stackelberg heuristic in which players assume that their strategic thinking will be anticipated by their co-player(s). Two-person games are called Stackelberg-soluble if the players' strategies that maximize against (...) their co-players' best replies intersect in a Nash equilibrium. Proofs are given that every game of common interests is Stackelberg-soluble, that a Stackelberg solution is always a payoff-dominant outcome, and that in every game with multiple Nash equilibria a Stackelberg solution is a payoff-dominant equilibrium point. It is argued that the Stackelberg heuristic may be justified by evidentialist reasoning. (shrink)

According to decision theory, the rational initial action in a sequential decision-problem may be found by backward induction or folding back. But the reasoning which underwrites this claim appeals to the agent's beliefs about what she will later believe, about what she will later believe she will still later believe, and so forth. There are limits to the depth of people's beliefs. Do these limits pose a threat to the standard theory of rational sequential choice? It is argued, first, that (...) the traditional solutions of certain games depend on knowledge which exceeds depth limits, and that these solutions therefore cannot be shown rational in the usual sense. Then, for that related reason even folding back solutions of one-person problems cannot be! A revision of our notion of rational choice is proposed, analogous to the reliabilist account of knowledge of Goldman and others, by which this paradox is resolved. (shrink)

A person is said to be ‘trust responsive’ if she fulfils trust because she believes the truster trusts her. The experiment we report was designed to test for trust responsiveness and its robustness across payoff structures, and to discriminate it from other possible factors making for trustworthiness, including perceived kindness, perceived need and inequality aversion. We elicit the truster’s confidence that the trustee will fulfil, and the trustee’s belief about the truster’s confidence after the trustee receives evidence relevant to this. (...) We find evidence of strong trust responsiveness. We also find that perceptions of kindness and of need increase trust responsiveness, and that they do so only in conjunction with trust responsiveness. (shrink)

Joint attention is recognised by many philosophers and psychologists as a fundamental cornerstone of our engagement with one another and the world around us. The most familiar paradigm of joint attention is joint perceptual—specifically visual—attention to an object in the present environment. However, some recent discussions have focused on a potentially different form of joint attention: namely, ‘joint reminiscing’ conversations in which two or more people discuss something in the past which they both remember. These exchanges are in some ways (...) comparable to joint perceptual attention to something present, and have been characterised by some as a form of joint attention to the past. In this paper, I will assess the prospects for characterising joint reminiscing as a genuine form of joint attention to the past, as understood on the model of joint perceptual attention to something present. My conclusions will be tentative, and my primary aim will be to explore how different commitments regarding the nature of both joint attention and episodic memory give rise to different possibilities for characterising joint reminiscing as a distinctive form of collective engagement with the past. I will suggest that joint reminiscing is unlike ordinary joint attention at least insofar as joint reminiscing trades on the participants’ mutual recognition of one another as having been present at an earlier experience. This is connected with joint reminiscing’s social function, and its role in facilitating the special kind of relationship conveyed by the idea of knowing a person. (shrink)

Playing with LEGO is naturally educational—it supports free play, imagination, and creativity. LEGO is forward‐thinking—it was one of the first toys to promote gender equality. LEGO advertises itself as a lifestyle choice whose values include being part of a team that educates people, that does the right thing, and that prides itself on its wholesomeness. This image is rather different from the reality of LEGO as a for‐profit company. The Greenpeace video undermines the entire ideology behind the LEGO brand and (...) everything it stands for. This chapter examines the relation between one's ideology and politics, on the one hand, and one's status as a consumer of LEGO toys, on the other. It also considers LEGO's long‐standing and problematic partnership with Shell. Shell, of course, is one of the world's largest and most profitable oil companies. The Greenpeace video hints at many possible criticisms of LEGO's relationship with Shell. (shrink)

This book defends a form of ethical intuitionism, according to which (i) there are objective moral truths; (ii) we know some of these truths through a kind of immediate, intellectual awareness, or "intuition"; and (iii) our knowledge of moral truths gives us reasons for action independent of our desires. The author rebuts all the major objections to this theory and shows that the alternative theories about the nature of ethics all face grave difficulties.

The first edition of The Scientific Background to Modern Philosophy took the dialogue of science and philosophy from Aristotle through to Newton. This second edition adds eight chapters, taking the dialogue through the Enlightenment and up to Darwin. This anthology is an attempt to help bridge the gap between the history of science and the history of philosophy.

Street art has exploded: it pervades our back alleys, surrounds us at bus-stops, covers billboards, competes with advertising and generally serves as urban wallpaper in most cities. But what is street art? A far cry from mere graffiti, street art has gained some social acceptance, but it remains neither officially sanctioned like public art, nor institutionally condoned, like its more traditional artistic cousins in museums. Somewhere in between these two extremes, street art has emerged, occupying a metaphysically suspect grey area (...) between illegal activity and bona fide art. This paper explores the nature of this emerging art form and draws out some of the differences between street art, public art and ‘mere’ graffiti. (shrink)

Virtually all philosophers agree that for a belief to be epistemically justified, it must satisfy certain conditions. Perhaps it must be supported by evidence. Or perhaps it must be reliably formed. Or perhaps there are some other "good-making" features it must have. But does a belief's justification also require some sort of awareness of its good-making features? The answer to this question has been hotly contested in contemporary epistemology, creating a deep divide among its practitioners. Internalists, who tend to focus (...) on scientific or theoretical beliefs as the ideal, insist that such awareness is required for justification. Externalists, who think children's ordinary beliefs in obvious facts are paradigm cases of justified belief, say it isn't required. Michael Bergmann's book offers a decisive refutation of internalism and a sustained defense of externalism. (shrink)

I argue that activists have co-opted street art as a tool for addressing epistemic injustices, injustices that result from negative identity prejudices that silence certain groups of people unfairly. To defend this claim, I explore the special nature of street art that makes it an especially appropriate tool for activists to enlist in the fight against epistemic injustices. From there, I will examine in detail two case studies which illustrate how street art is used to respond to and correct for (...) these injustices: first, the street art series, “Stop Telling Women to Smile” by Tatyana Fazlalizadeh, and then Chris Metzger’s Inside Out Project in Baltimore. Drawing on these examples, I highlight the features in virtue of which street art constitutes a particularly effective tool for correcting epistemic injustices. (shrink)

In this article, I explore the relationship between witness-bearing arts as a form of creative activism designed to respond to social injustices. In the first section, I present some common features of bearing witness, as conceptualized within media studies and journalism. Then I explain how artworks placed in the streets can bear witness in a similar way. I argue that witness-bearing art transmits knowledge about certain unjust and harmful events, which then places a moral burden or responsibility on the viewer. (...) To defend this view, I offer some examples of activist art that bears witness to certain events. I suggest that witness-bearing art is placed in the streets in order to make certain truths publicly available, by offering evidence of them embedded in the artwork. The final section considers why the bearing witness is especially effective for activist art. Witness-bearing art plays a crucial knowledge-transmitting function, one which enables art to engage in creative activism. I conclude by considering how witness-bearing art offers a powerful and persuasive voice for the oppressed. (shrink)

At the University of Sheffield during 2011 and 2012, a leading group of philosophers, psychologists, and others gathered to explore the nature and significance of implicit bias. The two volumes of Implicit Bias and Philosophy emerge from these workshops. Each volume philosophically examines core areas of psychological research on implicit bias as well as the ramifications of implicit bias for core areas of philosophy. Volume I: Metaphysics and Epistemology is comprised of two parts: “The Nature of Implicit Attitudes, Implicit Bias, (...) and Stereotype Threat,” and “Skepticism, Social Knowledge, and Rationality.” The first part contains chapters examining the relationship between implicit attitudes and “dual process” models of the mind; the role of affect in the formation and change of implicit associations; the unity (or disunity) of implicit attitudes; whether implicit biases are mental states at all; and whether performances on stereotype-relevant tasks are automatic and unconscious or intentional and strategic. The second part contains chapters examining implicit bias and skepticism; the effects of implicit bias on scientific research; the accessibility of social stereotypes in epistemic environments; the effects of implicit bias on the self-perception of members of stigmatized social groups as rational agents; the role of gender stereotypes in philosophy; and the role of heuristics in biased reasoning.

Externalist theories of justification create the possibility of cases in which everything appears to one relevantly similar with respect to two propositions, yet one proposition is justified while the other is not. Internalists find this difficult to accept, because it seems irrational in such a case to affirm one proposition and not the other. The underlying internalist intuition supports a specific internalist theory, Phenomenal Conservatism, on which epistemic justification is conferred by appearances.

In this engaging and spirited text, Michael Lynch argues that truth does matter, in both our personal and political lives. He explains that the growing cynicism over truth stems in large part from our confusion over what truth is.

Causation: A Realist Approach Traditional empiricist accounts of causation and laws of nature have been reductionist in the sense of entailing that given a complete specification of the non-causal properties of and relations among particulars, it is therefore logically determined both what laws there are and what events are causally related. It is argued here, however, that reductionist accounts of causation and of laws of nature are exposed to decisive objections, and thus that the time has come for empiricists to (...) break with that tradition. -/- The basic goal of this book, therefore, is to set out and defend realistic accounts of those concepts. In the case of causal relations, for example, Tooley maintains that causation is basically a matter of theoretical relations between states of affairs that underlie and explain relative frequencies. He also argues that such an approach avoids the objections that tell against reductionist accounts and that it does so without making causal relations epistemologically inaccessible. (shrink)

A popular claim in recent philosophy of mind and action is that events only exist once they are over. This has been taken to have the consequence that many temporal phenomena cannot be understood ‘from the inside’, as they are unfolding, purely in terms of events. However, as I argue here, the claim that events exist only when over is incoherent. I consider two ways of understanding the claim and the notion of existence it involves: one that ties existence to (...) the logic of quantification, and another that assimilates the existence of an event to that of a continuant. The first of these, I argue, cannot be the right way to understand the target claim, as there are serious logical obstacles to regarding this notion of existence as temporally variable. The second, on the other hand, leaves it ultimately mysterious what the existence of an event could amount to. I close with the suggestion that the undeniable temporal asymmetries which parties to the debate are interested in are properly understood in perspectival, not ontological, terms. (shrink)

Dignity plays a central role in current thinking about law and human rights, but there is sharp disagreement about its meaning. Combining conceptual precision with a broad historical background, Michael Rosen puts these controversies in context and offers a novel, constructive proposal. “Penetrating and sprightly...Rosen rightly emphasizes the centrality of Catholicism in the modern history of human dignity. His command of the history is impressive...Rosen is a wonderful guide to the recent German constitutional thinking about human dignity...[Rosen] is in (...) general an urbane and witty companion, achieving his aim of accessibly written philosophy.” —Samuel Moyn, The Nation “[An] elegant, interesting and lucid exploration of the concept of dignity...Drawing on classical, liberal and Catholic traditions, Rosen hopes to rehabilitate dignity to its rightful place near the centre of moral thought...Rosen's admirable book deserves wide attention from political theorists, jurisprudes and political philosophers.” —Simon Blackburn, Times Higher Education “Dignity deserves to be widely read, not only for its intrinsic interest, but also as a corrective to the habit of discussing such topics in abstraction from their social context. Whether or not one agrees with Rosen's arguments, there can be no doubt he has widened our horizons.” —Rae Langton, Times Literary Supplement. (shrink)

Our emotional lives are full of temporal asymmetries. Salient among these is that we tend to feel differently about painful or unpleasant events depending on their temporal location: we feel anxiety or trepidation about painful events we anticipate in the future, and relief when they are over. One question, then, is whether temporally asymmetric emotions such as relief have any ramifications for the metaphysics of time. On what has become the standard way of finessing this question, the asymmetry of relief (...) is an instance of the phenomenon of future-bias, a tendency to prefer painful events to be located in the past than in the future. The main question then posed is whether this pattern of preferences can be justified in the light of different metaphysical theories of time. In this paper I argue that this whole dialectic is misconceived. While many people may have future-biased preferences and these are a legitimate object of psychological study, this should be distinguished from the more basic phenomenon of relief that an unpleasant experience is over. Acknowledging the distinctness of these phenomena has two main consequences. First, if relief is not a manifestation of a time-biased preference, it is unclear what it would be for it to be justified or unjustified. This, in turn, should lead us to reassess how the psychology of relief bears on our metaphysical commitments. As I shall suggest, the real significance of the temporally asymmetric emotions for the metaphysics of time is that they manifest, and so reflection on them serves to draw our attention to, a structural feature of our awareness of the passage of time that resists re-articulation in other terms.

In this paper, I propose a new way of defining sport that I call a ‘core-periphery’ model. According to a core-periphery model, sport comes in degrees – what I refer to as ‘sport-likeness’ – and the aim of the philosopher of sport is to chart those dimensions along which an activity can be more or less a sport. By introducing the concept of sport-likeness, the core-periphery model complicates the picture of what is or is not a sport and encourages philosophers (...) interested in defining sport to engage with the social sciences in exploring the extension of the term sport in common usage. In this paper I present the results of a small survey about attitudes to sport, and use it to illustrate how a core-periphery definition of sport would proceed. (shrink)

This paper explores how engaging in and with philosophy in the streets has unique and special potential for children doing philosophy both inside and outside the classroom. We highlight techniques drawn from research into the political, social and activist potential of street art, and we illustrate how to apply these techniques in a P4C context in what we call guerrilla philosophy. We argue that guerrilla philosophy is a pedagogically powerful method to philosophically engage students whose ages range from 11-13. In (...) calling attention to the power of guerrilla philosophy to engage students philosophically, we are tacitly assuming a Deweyan philosophical approach, which emphasises the importance of promoting civic-mindedness as a social value; the reliance on imaginative, creative and experiential forms of learning as essential to education ; and a vision of the classroom as an embodiment of the larger civic community to which we all belong and in which we all must cooperate and engage. This paper traces these three themes in Dewey’s philosophical views of education and democracy, and considers how they are given a twenty-first century interpretation through street art, guerrilla philosophy and children’s activism.

While philosophers hold that it is patently absurd to blame robots or hold them morally responsible [1], a series of recent empirical studies suggest that people do ascribe blame to AI systems and robots in certain contexts [2]. This is disconcerting: Blame might be shifted from the owners, users or designers of AI systems to the systems themselves, leading to the diminished accountability of the responsible human agents [3]. In this paper, we explore one of the potential underlying reasons for (...) robot blame, namely the folk's willingness to ascribe inculpating mental states or "mens rea" to robots. In a vignette-based experiment (N=513), we presented participants with a situation in which an agent knowingly runs the risk of bringing about substantial harm. We manipulated agent type (human v. group agent v. AI-driven robot) and outcome (neutral v. bad), and measured both moral judgment (wrongness of the action and blameworthiness of the agent) and mental states attributed to the agent (recklessness and the desire to inflict harm). We found that (i) judgments of wrongness and blame were relatively similar across agent types, possibly because (ii) attributions of mental states were, as suspected, similar across agent types. This raised the question - also explored in the experiment - whether people attribute knowledge and desire to robots in a merely metaphorical way (e.g., the robot "knew" rather than really knew). However, (iii), according to our data people were unwilling to downgrade to mens rea in a merely metaphorical sense when given the chance. Finally, (iv), we report a surprising and novel finding, which we call the inverse outcome effect on robot blame: People were less willing to blame artificial agents for bad outcomes than for neutral outcomes. This suggests that they are implicitly aware of the dangers of overattributing blame to robots when harm comes to pass, such as inappropriately letting the responsible human agent off the moral hook.
