David Lewis is widely credited with the first formulation of common knowledge and the first rigorous analysis of convention. However, common knowledge and convention entered mainstream game theory only when they were formulated, later and independently, by other theorists. As a result, some of the most distinctive and valuable features of Lewis' game theory have been overlooked. We re-examine this theory by reconstructing key parts in a more formal way, extending it, and showing how it differs from more recent game (...) theory. In contrast to current theories of common knowledge, Lewis' theory is based on an explicit analysis of the modes of reasoning that are accessible to rational individuals and so can be used to analyse the genesis of common knowledge. Lewis' analysis of convention emphasises the role of inductive reasoning and of salience in the maintenance of conventions over time.

The authors explore the history of experiments in economics, provide examples of different types of experiments and show that the growing use of experimental methods is transforming economics into an empirical science.

We present a new class of models of players’ reasoning in non-cooperative games, inspired by David Lewis's account of common knowledge. We argue that the models in this class formalize common knowledge of rationality in a way that is distinctive, in virtue of modelling steps of reasoning; and attractive, in virtue of being able to represent coherently common knowledge of any consistent standard of individual decision-theoretic rationality. We contrast our approach with that of Robert Aumann, arguing that the former avoids (...) and diagnoses certain paradoxes to which the latter may give rise when extended in particular ways. (shrink)

This article reports an experiment which tests the principle of separability, i.e. that behaviour in a dynamic choice problem is independent of history and of unreachable eventualities. Although this is a well-known principle of orthodox decision theory and central to conventional economic modelling, it has been questioned on grounds suggested by non-expected utility models of choice under risk and by the psychology of affective influences on risk-taking. Our experimental design, which provides between-subjects tests of separability using three treatments in which (...) the history preceding a decision is manipulated, is inspired by these concerns. We expose separability to a clean and harsh test, but find no evidence that it is violated. (shrink)

In this paper, I address two connected issues that arise when one considers a rational agent facing a decision problem. One is whether or not the agent may find that the dictates of rationality are such that they cannot all be followed. For example, one may ask whether or not the requirements on the agent's actions imposed by rationality can conflict in an irreconcilable way, making it impossible to satisfy all of them. Put differently, one may ask whether or not (...) any apparent conflict of this type must in fact be capable of rational resolution. I shall say that an agent who is in a position in which the requirements of rationality cannot all be satisfied faces a feasibility dilemma, and I shall characterize certain conceptions of rationality that differ according to whether or not they admit such a possibility. A second issue concerns the number of options that may be deemed rational in a decision problem. Is rationality sufficiently determinate that it always dictates precisely one choice, or may there be more than one rationally permissible option? Is there anything about rationality itself that guarantees that any of the possible options could rationally be chosen? I shall call this issue – whether the concept of rationality itself places any limits on the number of options that may be deemed rational in a given problem – the numbers problem. (shrink)

We report an experiment where each subject’s ambiguity sensitivity is measured by an ambiguity premium, a concept analogous to and comparable with a risk premium. In our design, some tasks feature known objective risks and others uncertainty about which subjects have imperfect, heterogeneous, information. We show how the smooth ambiguity model can be used to calculate ambiguity premia. A distinctive feature of our approach is estimation of each subject’s subjective beliefs about the uncertainty in ambiguous tasks. We find considerable heterogeneity (...) among subjects in beliefs and ambiguity premia; and that, on average, ambiguity sensitivity is about as strong as risk sensitivity. (shrink)

In this paper, we defend two main claims. The first is a moderate claim: we have a negative duty to not use binary gender-specific pronouns he or she to refer to genderqueer individuals. We defend this with an argument by analogy. It was gravely wrong for Mark Latham to refer to Catherine McGregor, a transgender woman, using the pronoun he; we argue that such cases of misgendering are morally analogous to referring to Angel Haze, who identifies as genderqueer, as he (...) or she. The second is a radical claim: we have a negative duty to not use any gender-specific pronouns to refer to anyone, regardless of their gender identity. We offer three arguments in favor of this claim (which appeal to concerns about inegalitarianism and risk, invasions of privacy, and reinforcing essentialist ideologies). We also show why the radical claim is compatible with the moderate claim. Before concluding, we examine common concerns about incorporating either they or a neologism such as ze as a third-person singular gender-neutral pronoun. These concerns, we argue, do not provide sufficient reason to reject either the moderate or radical claim. (shrink)

Gender classifications often are controversial. These controversies typically focus on whether gender classifications align with facts about gender kind membership: Could someone really be nonbinary? Is Chris Mosier really a man? I think this is a bad approach. Consider the possibility of ontological oppression, which arises when social kinds operating in a context unjustly constrain the behaviors, concepts, or affect of certain groups. Gender kinds operating in dominant contexts, I argue, oppress trans and nonbinary persons in this way: they marginalize (...) trans men and women, and exclude nonbinary persons. As a result, facts about membership in dominant gender kinds should not settle gender classification practices. (shrink)

What’s important about ‘coming out’? Why do we wear business suits or Star Trek pins? Part of the answer, we think, has to do with what we call agential identity. Social metaphysics has given us tools for understanding what it is to be socially positioned as a member of a particular group and what it means to self-identify with a group. But there is little exploration of the general relationship between self-identity and social position. We take up this exploration, developing (...) an account of agential identity—the self-identities we make available to others. Agential identities are the bridge between what we take ourselves to be and what others take us to be. Understanding agential identity not only fills an important gap in the literature, but also helps us explain politically important phenomena concerning discrimination, malicious identities, passing, and code-switching. These phenomena, we argue, cannot be understood solely in terms of self-identity or social position. (shrink)

Alex Byrne’s article, “Are Women Adult Human Females?”, asks a question that Byrne treats as nearly rhetorical. Byrne’s answer is, ‘clearly, yes’. Moreover, Byrne claims, 'woman' is a biological category that does not admit of any interpretation as (also) a social category. It is important to respond to Byrne’s argument, but mostly because it is paradigmatic of a wider phenomenon. The slogan “women are adult human females” is a political slogan championed by anti-trans activists, appearing on billboards, pamphlets, and anti-trans (...) online forums. In this paper, I respond to Byrne’s argument, revealing significant problems with its background assumptions, content, and methodology. (shrink)

What responsibility do individuals bear for structural injustice? Iris Marion Young has offered the most fully developed account to date, the Social Connections Model. She argues that we all bear responsibility because we each causally contribute to structural processes that produce injustice. My aim in this article is to motivate and defend an alternative account that improves on Young’s model by addressing five fundamental challenges faced by any such theory. The core idea of what I call the “Role-Ideal Model” is (...) that we are each responsible for structural injustice through and in virtue of our social roles, i.e. our roles as parents, colleagues, employers, citizens, etc., because roles are the site where structure meets agency. In short, the Role-Ideal Model explains how individual action contributes to structural change, justifies demands for action from each particular agent, specifies what kinds of acts should be undertaken, moderates between demanding too much and too little of individual agents, and provides an account of the critical responses appropriate for holding individuals accountable for structural injustice.

In the 4th edition of this best-selling textbook, the authors introduce students to the business of philosophizing, thereby inducting them into the art of reasoning and analyzing key concepts in education. This introductory text, continuously in print for more than thirty years, is a classic in its field. It shows, first and foremost, the importance of philosophy in educational debate and as a background to any practical activity such as teaching. What is involved in the idea of educating a person (...) or the idea of educational success? What, if anything, can be known and how should we organize what we know for curriculum purposes? What are the criteria for establishing the optimum balance between formal and informal teaching techniques? How trustworthy is educational research? In addition to these questions, which strike to the heart of the rationale for the educative process as a whole, the authors explore such concepts as culture, creativity, autonomy, indoctrination, needs, interests and learning by discovery. In this new updated edition, the authors draw on the latest research in genetics to argue that education is uniquely human and is essentially what develops us as humans. Resisting modern tendencies to equate knowledge with opinion, and value judgments with taste, this book leads the reader into the business of philosophizing and champions the cause of reason in education.

Moral agency is limited, imperfect, and structurally constrained. This is evident in the many ways we all unwittingly participate in widespread injustice through our everyday actions, which I call ‘structural wrongs’. To do justice to these facts, I argue that we should distinguish between summative and formative moral criticism. While summative criticism functions to conclusively assess an agent's performance relative to some benchmark, formative criticism aims only to improve performance in an ongoing way. I show that the negative sanctions associated (...) with summative responses are only justifiably imposed under certain conditions when persons exercise their agency wrongly — conditions that do not always hold for structural wrongs. Yet even in such cases we can still use formative responses, which are warranted whenever agents fall short of moral ideals. Expanding our repertoire of moral criticism to include both summative and formative responses enables us to better appreciate both the powers and limitations of our agency, and the complexity of moral life.

The goal of this article is to show that mainstream liberal accounts of civil disobedience fail to fully capture the latter’s specific characteristics as a genuinely political and democratic practice of contestation that is not reducible to an ethical or legal understanding either in terms of individual conscience or of fidelity to the rule of law. In developing this account in more detail, I first define civil disobedience with an aim of spelling out why the standard liberal model, while providing (...) a useful starting point, ultimately leads to an overly constrained, domesticated and sanitized understanding of this complex political practice. Second, I place the political practice of civil disobedience between two opposing poles: symbolic politics and real confrontation. I argue that the irreducible tension between these poles precisely accounts for its politicizing and democratizing potential. Finally, I briefly examine the role of civil disobedience in representative democracies, addressing a series of recent challenges made in response to this radically democratic understanding of disobedience.

Sally Haslanger has recently argued that philosophical focus on implicit bias is overly individualist, since social inequalities are best explained in terms of social structures rather than the actions and attitudes of individuals. I argue that questions of individual responsibility and implicit bias, properly understood, do constitute an important part of addressing structural injustice, and I propose an alternative conception of social structure according to which implicit biases are themselves best understood as a special type of structure.

This paper investigates whether gender affects ethically sensitive decisions of a personal or business nature. Data from 51 practicing accountants from both public accounting and private industry suggest that while differences exist between female and male accountants in responses to specific situations, overall responses are quite similar. Statistically significant differences were found for only five of the sixteen ethically sensitive situations. Further, when personal and business situations of a similar nature were paired together, two of the eight differences between personal (...) and business responses were significantly different between females and males. Taken as a whole, the results refute the suggestion that the ethical decision making of organizations may be enhanced as more women enter the business field. (shrink)

This book provides an overview of recent debates about critical theory from Pierre Bourdieu via Luc Boltanski to the Frankfurt School. Robin Celikates investigates the relevance of the self-understanding of ordinary agents and of their practices of critique for the theoretical and emancipatory project of critical theory.

Iris Marion Young’s influential Social Connections Model of responsibility offers a compelling approach to theorizing structural injustice. However, the precise nature of the kind of responsibility modelled by the SCM, along with its relationship to the liability model, has remained unclear. I offer a reading of Young that takes the difference between the liability model and the SCM to be an instance of a more longstanding distinction in the literature on moral responsibility: attributability vs. accountability. I show that interpreting the (...) SCM as a conception of accountability resolves a number of objections, while also highlighting the SCM’s distinctive stance on the relationship between ethics and politics. (shrink)

What is objectionable about “blacking up” or other comparable acts of imagining involving unethical attitudes? Can such imaginings be wrong, even if there are no harmful consequences and imaginers are not meant to apply these attitudes beyond the fiction? In this article, we argue that blackface—and imagining in general—can be ethically flawed in virtue of being oppressive, in virtue of either its content or what imaginers do with it, where both depend on how the imagined attitudes interact with the imagining’s (...) context. We explain and demonstrate this using speech act theory alongside a detailed case study of blackface. (shrink)

In this peer commentary on Maura Priest's "Transgender Children and the Right to Transition: Medical Ethics When Parents Mean Well but Cause Harm", I argue against the "mismatch" model of trans identity. On this model, which is prevalent in institutional and medical contexts, to be trans is to have one's gender identity "mismatch" with one's sexed body.

One of the most important students of Franz Brentano was Anton Marty, who made it his task to develop a philosophy of language on the basis of Brentano’s analysis of mind. It is most unfortunate that Marty does not receive the attention he deserves, primarily due to his detailed and distracting polemics. In the analysis presented here his philosophy of language and other aspects of his thought, such as his ontology , are examined first and foremost in their positive rather (...) than critical character. The analysis is moreover supplemented by translations of four important works by Marty, including his entire work On the Origin of Language. These are in fact the first English translations of any substantial writings by him. The resulting picture that emerges from the analysis and translations is that Marty has much to say that proves to be of enduring interest for the philosophy of language on a range of topics, especially the meanings of statements, of emotive expressions, and of names as regards both their communicative and their ontological aspects. The volume will be of interest not only to philosophers and historians of philosophy, but also to historians of linguistics and psychology. (shrink)

Mechanisms are the how of chemical reactions. Substances are individuated by their structures at the molecular scale, so a chemical reaction is just the transformation of reagent structures into product structures. Explaining a chemical reaction must therefore involve different hypotheses about how this might happen: proposing, investigating and sometimes eliminating different possible pathways from reagents to products. One distinctive aspect of mechanisms in chemistry is that they are broken down into a few basic kinds of step involving the breaking and (...) making of bonds between atoms. This is necessary for chemical kinetics, the study of how fast reactions happen, and what affects it. It draws on G.N. Lewis’ identification of the chemical bond as involving shared electrons, which from the 1920s achieved the commensuration of chemistry and physics. The breaking or making of a bond just is the transfer of electrons, so a chemical bond on one side of an equation might be balanced on the other side by the appearance of a corresponding quantity of excess charge. A bond is understood to have been exchanged for a pair of electrons. Since reaction mechanisms rely on identities, doesn’t the establishment of a reaction mechanism explain away the chemical phenomena, showing that they are no more than the movement of charges and masses? In one sense yes: these mechanisms seem to involve a conserved-quantity conception of causation. But in another sense no: the ‘lower-level’ entities can do what they do only when embedded in higher-level organisation or structure. There need be no threat of reduction. (shrink)

Ordinary discourse is filled with discussions about ‘sexual orientation’. This discourse might suggest a common understanding of what sexual orientation is. But even a cursory search turns up vastly differing, conflicting, and sometimes ethically troubling characterizations of sexual orientation. The conceptual jumble surrounding sexual orientation suggests that the topic is overripe for philosophical exploration. This paper lays the groundwork for such an exploration. In it, I offer an account of sexual orientation – called ‘Bidimensional Dispositionalism’ – according to which sexual (...) orientation concerns what sex[es] and gender[s] of persons one is disposed to sexually engage, and makes no reference to one’s own sex and gender.

We want to know what gender is. But metaphysical approaches to this question solely have focused on the binary gender kinds men and women. By overlooking those who identify outside of the binary–the group I call ‘genderqueer’–we are left without tools for understanding these new and quickly growing gender identifications. This metaphysical gap in turn creates a conceptual lacuna that contributes to systematic misunderstanding of genderqueer persons. In this paper, I argue that to better understand genderqueer identities, we must recognize (...) a new type of gender kind: critical gender kinds, or kinds whose members collectively destabilize one or more pieces of dominant gender ideology. After developing a model of critical gender kinds, I suggest that genderqueer is best modeled as a critical gender kind that destabilizes the ‘binary axis’, or the piece of dominant gender ideology that says that the only possible genders are the binary, discrete, exclusive, and exhaustive kinds men and women.
