AbstractThis article brings together two sets of insights about deliberative democracy and uses them to develop a novel epistemic justification for the importance of testimony. Some democratic theorists have argued persuasively that a deliberative process limited to formal argumentation is exclusionary and thus undermines democratic legitimacy; they have made a compelling case for testimony on grounds of democratic inclusion. Others have made the case that deliberation has important epistemic benefits. Those theorists emphasize the give and take of reasons as a means to arrive at well-informed collective decisions. The author’s central claim is that there is an important epistemic value to the inclusion of testimony. It can introduce new information into the deliberative process. It can enable deliberators to grasp connections between the particular and the general. And it can invite them to imaginatively engage with the experiences of others. These epistemic benefits provide a new set of reasons for including testimony in democratic deliberation.
