This collection of 19 chapters, all appearing in print here for the first time and written by an international team of established and emerging scholars, explores the place of intellectual virtues and vices in a social world. Relevant virtues include open-mindedness, curiosity, intellectual courage, diligence in inquiry, and the like. Relevant vices include dogmatism, need for immediate certainty, and gullibility and the like.

The chapters are divided into four key sections: Foundational Issues; Individual Virtues; Collective Virtues; and Methods and Measurements. And the chapters explore the most salient questions in this areas of research, including: How are individual intellectual virtues and vices affected by their social contexts? Does being in touch with other open-minded people make us more open-minded? Conversely, does connection to other dogmatic people make us more dogmatic? Can groups possess virtues and vices distinct from those of their members? For instance, could a group of dogmatic individuals operate in an open-minded way despite the vices of its members?

Each chapter receives commentary from two other authors in the volume, and each original author then replies to these commentaries. Together, the authors form part of a collective conversation about how we can know about what we know. In so doing, they not only theorize but enact social virtue epistemology.
