According to Kirk Ludwig, only primitive actions are actions in a primary and non-derivative sense of the term ‘action’. Ludwig takes this to imply that the notion of collective action is a façon de parler – useful perhaps, but secondary and derivative. I argue that, on the contrary, collective actions are actions in the primary and non-derivative sense. First, this is because some primitive actions are collective actions. Secondly, individual and collective composites of primitive actions are also actions in the (...) primary and non-derivative sense. Hence, individual action and collective action are ontologically on a par. Ludwig also exaggerates the contrast between individual and collective action by introducing a “sole agency requirement” in his account of the semantics of singular action sentences. However, sole agency is merely typically pragmatically implicated by singular action sentences, not entailed by them. If I say, “I turned on the light”, after we each flipped one of two switches that together turned on the light, then I might be misleading the audience, but what I say is true. Finally, I argue that, contra Ludwig, individuals often have “I-intentions” to bring about an event that can be satisfied even if there are co-agents who bring about the event in the same way.

What is required for several agents to intentionally φ together? I argue that each of them must believe or assume that their φ-ing is a single end that each intends to contribute to. Various analogies between intentional singular action and intentional joint action show that this doxastic single end condition captures a feature at the very heart of the phenomenon of intentional joint action. For instance, just as several simple actions are only unified into a complex intentional singular activity if (...) the agent believes or assumes that there is a single end that each action is directed to, so several agents’ actions are only unified into an intentional joint activity if each agent believes or assumes that there is a single end that each intends to contribute to. Influential accounts of intentional joint action, including Christopher Kutz’s and Michael Bratman’s, implicitly include this condition only if participants must intend to contribute to the end under the same conception. While such a requirement successfully rules out some counterexamples, it also makes the accounts unable to appropriately accommodate and explain clear cases of intentional joint action that they ought to be able to accommodate and explain.

In this paper, I examine the manner in which analyses of the action of single agents have been pressed into service for constructing accounts of collective action. Specifically, I argue that the best analogy to collective action is a class of individual action that Carl Ginet has called 'aggregate action.' Furthermore, once we use aggregate action as a model of collective action, then we see that existing accounts of collective action have failed to accommodate an important class of (what I (...) shall call) 'unintentional collective actions.'.
