Groups as epistemic and moral agents

This book takes seriously the idea that at least some groups, such as corporations and governments, are genuine agents with mental states on which they act. For instance, in morally assessing a government’s response to the coronavirus pandemic, we are interested in what the government knew at various points as the pandemic developed. And in predicting the outcome of the current war in Ukraine, we might ask what Russia believes about the West’s determination to defend Ukraine. The book examines a range of phenomena central to the epistemic and moral assessment of groups: group evidence, group belief, the basis of group belief, group justified belief, group knowledge, group motivation, and group blameless ignorance. Overall, the book defends a ‘non-summative’ functionalist view of groups. On a non-summative account of group phenomena, it is neither necessary nor sufficient for a group to have a property α that some/most/all of its members have that same property. By contrast, on a summative account it is necessary and sufficient for a group to have a property α that some/most/all of its members have that same property. Across the book I provide new arguments for non-summativism and new accounts of key group phenomena many of which have been relatively neglected in existing literature. While I provide independent arguments for a non-summative view of each phenomenon discussed, the conclusions of the chapters are mutually reinforcing. For adopting a non-summative account of one group phenomenon motivates adopting a non-summative account of others.
