Despite the recent growth of studies in virtue epistemology, the intellectual virtue of epistemic collaborativeness has been overlooked by scholars working in virtue theory. This is a significant gap in the literature given the import of well-motivated and skillful epistemic collaboration for the flourishing of human societies. This paper engages in an in-depth examination of the intellectual virtue of epistemic collaborativeness. It argues that the agent who possesses this acquired character trait is highly motivated to engage in epistemic collaboration, competent (...) at the characteristic activity of epistemic collaborativeness and has good judgement as to when and with whom it is epistemically appropriate to engage in epistemic collaboration. Furthermore, this paper discusses the place of epistemic collaborativeness among the virtues and argues that it is an overarching virtue—i.e. it presupposes certain other intellectual virtues although it remains distinguishable from them. Theoretical and practical merits of this virtue are also presented and considered. The virtue of collaborativeness highlights the social dimension of intellectual virtues and could be of significant value for contemporary virtue-based approaches to education. (shrink)
