We have the capacity to act together in shared intentional and shared cooperative ways. This lecture argues that our capacity for the plan-based, mind-supported cross-temporal organization of our individual activities, together with certain further elements, suffices for our capacity for the mind-supported, small-scale social organization characteristic of acting together. These two fundamental forms of human practical organization––diachronic and small-scale social––are for us grounded in a common core: our capacity for planning agency.

I argue for an account of acting together that has a particular notion of joint commitment at its core. The account presented offers a compact explanation of four significant aspects of acting together as this is ordinarily understood: the parties have pertinent obligations to one another; each needs the concurrence of the rest with his or her untimely exit from the joint activity; an appropriate collective goal is sufficient to motivate the parties; and the parties may have personal goals contrary to the collective goal. I argue that the simplicity of the account coupled with its explanatory power argue for it in face of concerns that it takes us beyond the concepts we need to explain what it is for an individual to act alone. Indeed, there is reason to invoke joint commitment in many contexts other than acting together in which more than one person is involved. I conclude by noting that the joint commitment account of acting together plausibly accounts for the apparently transformative nature of doing things with others, citing its connection with a sense of togetherness, solidarity, and unity, as in the phrase ‘There is no I in team’.

In her 2021 Lebowitz Prize Lecture, ‘A Simple Theory of Acting Together’, Margaret Gilbert seeks to articulate the ‘idea’ of acting together that ‘animates’ our commonsense talk about this important phenomenon. I seek a model that provides illuminating sufficient conditions for this phenomenon. As I see it, these are not quite the same project. After all, our commonsense idea and talk may well have two interrelated faces: an inchoate understanding of what the phenomenon is; and an inchoate understanding of norms about, very roughly, what those who participate in this phenomenon normally thereby owe to each other. Gilbert develops a rich and complex articulation of this second element, one according to which the interpersonal obligations in question are not in general moral obligations. Broadly speaking, her strategy is then to take this web of interpersonal obligations and the like and directly build it into her account of what the phenomenon of acting together is. This leads her to say that that phenomenon involves a non-reducible phenomenon in which A and B are ‘jointly committed to endorse G as a body’––where such joint commitments are constituted at least in part by the interpersonal obligations and the like to which our commonsense idea of acting together alludes.

I start by emphasizing two aspects of Michael Bratman's approach to shared agency and contrast it with my own in those respects. I conclude with some related remarks on the relation of morality and joint commitment.

In this article I contrast two opposing forms of essentialism, definitional and transcendental versus productivist and historical, and trace both forms back to Kripke's Naming and Necessity (1980). Definitional essentialism, as developed by Fine, centers on kind-membership. Historical essentialism, as anticipated by Prior and developed by Almog, puts origin at its center. The article focuses on the fundamentally distinct manners in which these two views handle the necessity of origin thesis. In the final section of the article, inspired by a Nietzschean genealogical methodology, I pursue a naturalization strategy and conclude that rather than origin being necessary, it is essentialist necessity that reduces to origin.

This paper explores a novel notion of self-explanation that combines ideas from two sources: (1) the tripartite account of explanation, according to which a proposition can help explain another either in the capacity of a reason why the latter obtains or in the capacity of an explanatory link, and (2) the notion of an empty-base explanation, which generalizes the ideas of explanation by zero-grounding and explanation by status. After having introduced these ideas and the novel notion of self-explanation, I argue that the latter has the potential to resist extant arguments against the possibility of self-explanation. In the remainder of the paper, I discuss candidates for such self-explanatory propositions and suggest possible applications for Humeanism about laws of nature, the debate on the grounds of ground, the rationalist tradition, and philosophical theology.

The topic of fake news has received increased attention from philosophers since the term became a favorite of politicians. Notably missing from the conversation, however, is a discussion of fake news and conspiracy theory media as a market. This paper will take as its starting point the account of noxious markets put forward by Debra Satz and will argue that there is a pro tanto moral reason to restrict the market for fake news. Specifically, we begin with Satz's argument that restricting a market may be required when (i) that market inhibits citizens from being able to stand in an equal relationship with one another, and (ii) this problem cannot be solved without such direct restrictions. Our own argument then proceeds in three parts: first, we argue that the market for fake news fits Satz's description of a noxious market; second, we argue against explanations of the proliferation of fake news that are couched in terms of ‘epistemic vice’ and likewise argue against prescribing critical thinking education as a solution to the problem; finally, we conclude that, in the absence of other solutions to mitigate the noxious effects of the fake news market, we have a pro tanto moral reason to impose restrictions on this market. At the end of the paper, we consider one proposal to regulate the fake news market, which involves making social media outlets potentially liable in civil court for damages caused by the fake news hosted on their websites.

Motivating reforms to address discrimination and exclusion is important. But what epistemic practices characterize better or worse ways of doing this? Recently, the phenomena of implicit biases have played a large role in motivating reforms. We argue that this strategy risks perpetuating two kinds of epistemic oppression: the vindication dynamic and contributory injustice. We offer positive proposals for avoiding these forms of epistemic oppression when confronting racism.

This paper defends an account of moral shock as an emotional response to intensely bewildering events that are also of moral significance. This theory stands in contrast to the common view that shock is a form of intense surprise. On the standard model of surprise, surprise is an emotional response to events that violated one's expectations. But I show that we can be morally shocked by events that confirm our expectations. What makes an event shocking is not that it violated one's expectations, but that the content of the event is intensely bewildering (and bewildering events are often, but not always, contrary to our expectations). What causes moral shock is, I argue, our lack of emotional preparedness for the event. And I show that, despite the relative lack of attention to shock in the philosophical literature, the emotion is significant to moral, social, and political life.

It is common to criticize certain comments as ‘unhelpful’. This criticism is richer than it might first appear. In this paper, I sketch an account of conversational helpfulness and unhelpfulness, the reasons why they matter, and the utility of calling out comments as helpful or unhelpful. First, some unhelpful comments are or easily could be demoralizing for proponents of projects, and criticizing them as such can diminish, deflect, or defend against that demoralization. Second, some unhelpful comments redirect or derail conversations away from their projects and criticizing comments as unhelpful can steer conversations back. Third, some unhelpful comments are made out of a lack of epistemic effort and criticizing them as such can help maintain epistemic standards, standards of respect for other people and their projects, and can ensure that such comments do not receive more attention and consideration than they deserve.

Understanding and empathy on the part of those in privileged positions are often cited as powerful tools in the fight against oppression. Too often, however, those in positions of power assume they know what it is like to be less well off when, in actuality, they do not. This kind of assumption represents a thinking vice we dub synecdoche epistemic arrogance. In instances of synecdoche epistemic arrogance, a person who has privilege wrongly assumes, based on limited experiences, that she can know what it is like to experience a particular form of oppression. We argue two main points. First, synecdoche epistemic arrogance can lead to a variety of moral harms. Second, synecdoche epistemic arrogance is often tied to other troubling epistemic patterns, which we discuss in the context of disability and race simulations. Overall, the essay helps demonstrate how synecdoche epistemic arrogance can contribute to injustice.

Here I speak in favor of the view that life's meaning can be found in the pursuit of pleasure. I first present an argument for this view that is grounded in a traditional concept of meaning. To help ease remaining concerns about accepting it, I then draw attention to four things the view does not imply: (1) that we have a reason to take hedonistic theories of meaning seriously; (2) that meaning can be found in the deeply immoral, the deeply ignorant, or the deeply repulsive pursuit of pleasure; (3) that there is a significantly easier route to meaning than the pursuit of morality, the pursuit of knowledge, or the pursuit of art; and (4) that meaning can be found in pursuits that involve only baser aspects of human nature.
