Testimonial Trustworthiness
Truthfulness and Trust

Believing someone is, as Elizabeth Anscombe said, “trusting him for the truth.” Recent accounts of how we trust speakers for the truth have given a central role to speaker trustworthiness but have said little about what speaker trustworthiness is. I argue that it is best to think of speaker trustworthiness as the virtue of truthfulness. I give an account of truthfulness, show how that account solves problems for other accounts of speaker trustworthiness, and then use my account to explain the epistemic benefits of trusting a truthful speaker.
