Two Faces of Our Idea of Acting Together

Abstract

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.
