Epistemologists have recently started appealing to the moral philosophy literature on interpersonal trust in order to help explain the epistemology of testimony. We argue that epistemologists who have given trust a significant role in their accounts of the epistemology of testimony have appealed to very different conceptions of the nature of trust, which have inevitably influenced the shape of their epistemological theorizing. Some have employed accounts of the nature of interpersonal trust according to which trust is a practical phenomenon subject (...) to the will and to practical reasoning. Such accounts face the task of showing how the practical phenomenon that is interpersonal trust has epistemic implications for testimonial belief. Other theorists have employed accounts of the nature of interpersonal trust according to which trust is at least partly a cognitive phenomenon, itself subject to epistemic norms. Such accounts do not face the task of showing how practical rationality has implications for theoretical reason. Instead, they face the rather different tasks of showing how it is that cognitive trusting bears genuinely interpersonal features, and of how theoretical rationality can share features with practical rationality.

In this paper, I explore what gives collective testimony its epistemic credentials, through a critical discussion of three competing accounts of the epistemology of collective testimony. According to the first view, collective testimony inherits its epistemic credentials from the beliefs the testimony expresses— where this can be seen either as the beliefs of all or some of the group’s members, or as the beliefs of group itself. The second view denies any necessary connection to belief, claiming instead that the epistemic (...) credentials of collective testimony derive from the reliability or truth-conduciveness of the statement that expresses the testimony. Finally, the third view claims that the epistemic credentials of collective testimony derive from the fact that it involves undertaking a collective commitment to trustworthiness, which makes the group susceptible to rebuke and blame if its testimony is not trustworthy. I argue that this last account holds the most promise for preserving what is distinctive about testimonial knowledge while still underwriting a robust epistemology of collective testimony. (shrink)
