Word-taking has both an epistemic and an ethical dimension. I argue that we have no good way of understanding how both ethical and epistemic considerations can be brought to bear when someone makes up her mind to take another at her word, even as we recognize that they must. This difficulty runs deep, and takes the familiar form of a sceptical problem. It originates in an otherwise powerful and compelling way of thinking about what distinguishes theoretical from practical reason. But (...) that picture breaks down, especially in hard cases, where we find ourselves pulled in opposed directions by our ethical and epistemic responsibilities. My primary interest is in diagnosing the problem, to which I do not see any easy solution. However, at the end of the paper, I suggest three issues that deserve more attention in thinking about how the problem might be solved. (shrink)
