On the special insult of refusing testimony

In this paper, I defend the claim, made by G. E. M. Anscombe and J. L. Austin, that you can insult someone by refusing her testimony. I argue that refusing someone's testimony can manifest doubt about her credibility, which in the relevant cases is offensive to her, given that she presupposed her credibility by telling what she did. I conclude by sketching three applications of my conclusion: to the issue of valuable false belief, to the issue of testimonial injustice, and to the issue of skepticism about testimonial knowledge.
