The main aim of this chapter is to explore the importance of moral testimony for testifiers. Up to now, writers on moral testimony have by and large focused on how moral testimony impacts dependers. And, in doing so, they’ve tended to theorize about moral testimony assuming a rather abstracted picture of the testifier according to which all that really matters about her is that she’s a credible source. In contrast, this chapter shows how paying attention to the fact that testifiers are not just potential informants but also socially embedded moral agents helps us to discern heretofore unrecognized ways that moral testimony is valuable. More specifically, this chapter argues that dependence on moral testimony is valuable because it can promote the moral development of testifiers. Furthermore, dependence on moral testimony can be a way of respecting and standing by those who are oppressed in the face of their systematic moral subordination. And, finally, for oppressed persons, giving moral testimony can function as a way of resisting oppressive constructions of identity and expressing and retaining self-respect.
