 The analysis of collective attitudes raises questions about the nature of group minds more generally, and whether or not they are to be understood as extensions of individual properties applied to groups. A number of theorists take a functionalist approach to group minds and agency. On this approach, group agents or group cognitive systems are understood to function in a similar way as individuals do, at a certain level of description. A widely accepted theory of individual agency is that people have a modular system that we use to navigate the world. We have beliefs, knowledge, form intentions, plan, reason, and take action. All of these components can be described in terms of their functional contributions to the system, and they integrate with one another to perform unified functions. They compose, in other words, a “system of practical activity”. Group agency is understood on this model: for group agents, the same functional system is realized, but by groups or distributed systems rather than by individuals. (See Bratman 1987, 1993, 2014; List &amp; Pettit 2011; Theiner &amp; O’Connor 2010; Theiner 2014; Epstein forthcoming). List and Pettit argue that such realizers constitute new “loci of agency”, or “groups with minds of their own”.
