 Greco (2007) responds that Morris still deserves credit for learning the truth. Credit for cooperative success can accrue to multiple individuals, even ones who contribute less than others. It generally requires only that your “efforts and abilities” be “appropriately involved” in the success (Greco 2007: 65).   Further developing this idea, Greco points out that intellectual virtues are often social virtues, exercised in social environments.  For example, various social-cognitive abilities are involved in assessments of speaker competence and sincerity, and so important for the reception of testimony.  A different kind of response proposes that knowledge-producing virtues are often seated not in the individual knower, but in the broader intellectual community. On such occasion, knowledge continues to be understood as “produced from virtue,” but the virtues in questions are now community virtues rather than those of an individual knower. By far, the most common analogy for such approaches is teamwork in sports (Green 2017). Let us distinguish between a) several individuals constituting a group agent, which agent is in turn the locus of group intentions and actions, and b) several individual agents doing something together.  The latter kind of cooperation is often referred to as “shared” or “joint” agency, as distinguished from group agency. Greco (2020) uses a joint agency framework to understand testimonial knowledge. The guiding idea is that the transmission of knowledge from speaker to hearer involves the kind of cooperation that constitutes joint agency. On this view, the resulting testimonial knowledge is not attributable to the competent individual agency of the hearer, but rather to the competent joint agency of speaker and hearer acting together. In that sense, transmitted knowledge is understood as a joint achievement rather than an individual achievement.
