Group Belief for a Reason

Abstract

Many philosophers treat groups as morally responsible agents with beliefs and aims in the light of which they act. Assuming that groups do have beliefs, an important issue concerns what it is for a group to believe something for a reason. The reason for which a subject believes something affects whether her belief is justified, and its degree of justification. For instance, even if a detective has excellent evidence for believing that Mr Big committed the crime, if her belief is based instead on wishful thinking then her belief is not justified. In this paper I investigate what it is for a group to believe something for a reason. I defend a non-summative account on which a group can believe that p for a reason even though none of its members believe that p for that reason. By contrast, a summative account would hold that the reason for which a group believes that p is a function of the reason(s) for which its members believe that p. I argue that the proposed non-summative account deals better with cases in which members of a group believe that p for different reasons. I also defend it against a range of objections including that it conflicts with epistemic norms for assertion and action.
