Accepting a promise is normatively significant in that it helps to secure promissory obligation. But what is it for B to accept A’s promise to φ? It is in part for B to intend A’s φ-ing. Thinking of acceptance in this way allows us to appeal to the distinctive role of intentions in practical reasoning and action to better understand the agency exercised by the promisee. The proposal also accounts for rational constraints on acceptance, and the so-called directedness of promissory (...) obligation. Finally, the proposal, conjoined with Cognitivism about intentions, addresses recent criticism of Scanlon’s expectation-based view of promissory obligation. (shrink)

My concern here is to motivate some theses in the philosophy of mind concerning the interpersonal character of intentions. I will do so by investigating aspects of shared agency. The main point will be that when acting together with others one must be able to act directly on the intention of another or others in a way that is relevantly similar to the manner in which an agent acts on his or her own intentions. What exactly this means will become (...) clearer once we understand what it is to act directly on one’s own intentions. But I take it to be a fundamental assumption of the prevailing individualism of the theory of action— one at the core of its conception of the separateness of individuals— that one person cannot act directly on another’s intention. I agree that there is an important way in which we are or can be separate and autonomous thinkers and agents. But the way the individualist tries to capture this separateness is misguided. (shrink)

Sometimes individuals act together, and sometimes each acts on his or her own. It's a distinction that often matters to us. Undertaking a difficult task collectively can be comforting, even if only for the solidarity it may engender. Or, to take a very different case, the realization (or delusion) that the many bits of rudeness one has been suffering of late are part of a concerted effort can be of significance in identifying what one is up against: the accumulation of (...) grievances (no doubt well catalogued) is seen, not as an unfortunate coincidence of affronts stemming from various quarters, but as itself a product of a unified exercise of agency. A paranoid conspiracy theorist is not usually to be taken seriously. But he does get right that it certainly would be awful, for example, if everyone were out to get him and were working together to do so. After all, the stability and impact of agency that's shared can be expected to be more serious than the effects of a mere collection of individual acts.[1.. (shrink)

Shared activity is often simply willed into existence by individuals. This poses a problem. Philosophical reflection suggests that shared activity involves a distinctive, interlocking structure of intentions. But it is not obvious how one can form the intention necessary for shared activity without settling what fellow participants will do and thereby compromising their agency and autonomy. One response to this problem suggests that an individual can have the requisite intention if she makes the appropriate predictions about fellow participants. I argue (...) that implementing this predictive strategy risks derailing practical reasoning and preventing one from forming the intention. My alternative proposal for reconciling shared activity with autonomy appeals to the idea of acting directly on another's intention. In particular, I appeal to the entitlement one sometimes has to another's practical judgment, and the corresponding authority the other sometimes has to settle what one is to do. (shrink)

The intentions of others often enter into your practical reasoning, even when you’re acting on your own. Given all the agents around you, you’ll come to grief if what they’re up to is never a consideration in what you decide to do and how you do it. There are occasions, however, when the intentions of another figure in your practical reasoning in a particularly intimate and decisive fashion. I will speak of there being on such occasions a practical intersubjectivity of (...) intentions holding between you and the other individual. I will try to identify this practical intersubjectivity, and to take some preliminary steps toward giving a philosophical account of it. Occasions of practical intersubjectivity are usually those where individuals share agency, or do things jointly, such as when they walk together, kiss, or paint a house together. I will not assume that all instances of practical intersubjectivity are instances of shared agency. But the converse is true: any instance of shared agency involves a practical intersubjectivity holding between the participants. An account of shared agency is inadequate if it fails to handle practical intersubjectivity. The paper is structured as follows. In section 1, I present an example to illustrate this idea of practical intersubjectivity, at least as it appears in the context of shared agency. Practical intersubjectivity is a normative phenomenon, and it is on this basis that in section 2 I distinguish it from the mere coordination of intentions some have recognized as essential for shared activity. The task of section 3 is to show how practical intersubjectivity cannot be adequately described in terms of ordinary intentions familiar from the study of individual agency. Such approaches fail to handle the rational dynamics of intention revision when practical.. (shrink)

Socializing Metaphysics supplies diverse answers to the basic questions of social metaphysics, from a broad array of voices. It will interest all philosophers and social scientists concerned with mind, action, or the foundations of social theory.

An appreciation of Hume’s psychology of object identity allows us to recognize certain tensions in his discussion of the origin of our belief in personal identity---tensions which have gone largely unnoticed in the secondary literature. This will serve to provide a new solution to the problem of explaining why Hume finds that discussion of personal identity so problematic when he famously disavows it in the Appendix to the Treatise. It turns out that the two psychological mechanisms which respectively generate the (...) ideas of object and of personal identity are mutually incompatible. It is this sort of conflict within Hume’s introspective or subjectivist psychology which is the source of his worry. (shrink)

Davidson held that the explanation of action in terms of reasons was a form of causal explanation. He challenged anti-causalists to identify a non-causal relation underlying reasons---explanation which could distinguish between merely having a reason and that reason being the one for which one acts. George Wilson attempts to meet Davidson’s challenge, but the relation he identifies can serve only in explanations of general facts, whereas reasons explanation is often of particular acts. This suggests that the relation underlying reasons explanation (...) is not only causal, but singular as well. A further proposal, extracted from Fred Dretske’s views, characterizes this singular causal relation in terms of non-mental triggers. But this suggestion underestimates the explanatory role of the environment at the time of action, and shares with Wilson’s proposal the inability to account for the rationalization of particular acts. A situational environmentalist conception of reasons explanation, however, does not face these difficulties. (shrink)

In an important new book on shared agency, Michael Bratman develops an account of the normative demand for the coordination of intentions amongst participants in shared agency. Bratman seeks to understand this form of normative guidance in terms of that associated with individual planning intentions. I give reasons to resist his form of reductionism. In addition, I note how Bratman’s discussion raises the interesting issue of the function or purpose of shared intention and of shared agency more generally. According to (...) Bratman, the function of shared intention is to promote interpersonal coordination of intention and action. I suggest that power sharing amongst participants must also be included as a function of shared intention. (shrink)

Much of what Hume calls probable reasoning is deliberate and reflective. Since there are aspects to Hume’s psychology that tempt some commentators to think, on the contrary, that for Hume all such reasoning is simple and immediate, I will be concerned to emphasize Hume’s recognition of the sophisticated sort of probable reasoning (section I). Though some of the details of my case may be new, the overall point of this section should not be news to recent scholarship. But once we (...) recognize that this reflective and deliberate reasoning constitutes a significant portion of all probable reasoning, it becomes legitimate to ask how Hume accommodates this reasoning in his psychology, his ‘science of man.’ I believe that ..

Before one can give a fully adequate account of action, one must know where the action is. This amounts to understanding the nature of basic or unmediated action, the performance of which does not require performing any other act as a means. There is little consensus on what sort of act is basic. Volitionists such as H. A. Prichard, Brian O'Shaughnessy, Jennifer Hornsby and Carl Ginet, hold that a special type of mental act is basic and underlies all overt bodily (...) action. They believe that action, in its fundamental form, occurs in the head or mind of the agent that performs it. "Corporealists" like Donald Davidson hold that the basic act is one of bodily movement. Finally, "environmentalists" include events beyond the body as part of the basic act. ;The dissertation is devoted to establishing the viability and exploring the ramifications of the environmentalist conception of basicness. Ideas of various theorists are discussed, including Donald Davidson, G. E. M. Anscombe, George Wilson, Gilbert Harman, John Searle, Alfred Mele, Tyler Burge, and John Perry. I address a number of arguments for volitionism or corporealism which draw upon some aspect of action, such as its individuation , its description , its rationalization , and its intentionality or content--in particular its self-referential content . Discussions of these topics serve to further articulate the environmentalist notion that in acting we can have an unmediated or direct effect upon our surroundings. A defense of environmentalism offers, in turn, a new understanding of these various aspects of action. (shrink)
