Essays in Collective Epistemology

We routinely ascribe both belief and knowledge to collective entities. We say that the Bush administration knew that no weapons of mass destruction were found in Iraq, that the philosophy department believes its hiring decision complies with employment law, or that we know that greenhouse gas emissions cause climate change. Collective epistemology studies the nature of collective belief, justification, and knowledge. This volume contains ten original articles, five of which are centrally concerned with collective epistemology so understood. The other five take up a number of issues that fall into the wider area of social epistemology.
