Abstract
The starting?point for this discussion is Rolf Gruner's ?On the Action of Social Groups? (Inquiry, Vol. 19 [1976]), in which it is argued that assemblies and institutions can be said to perform actions, while classes cannot. It is shown here that teams, which are groups distinct from both assemblies and institutions, can also be said to act. Some of the similarities and differences between teams and assemblies and institutions are noted; and, in particular, it is found that the relation between the action of a team and the actions of its members differs from the corresponding relations in the cases of assemblies and institutions
