Abstract
The practice of ascribing dispositions of communicative truthfulness to others is necessary if language-use is to be effective. In this article, through a phenomenological analysis of everyday judgments about the sincerity and honesty of others, the author shows that, in learning to employ these two distinct concepts correctly, users of language are learning that communicative truthfulness is morally significant insofar as it manifests fairness (in the case of honesty) and the goods of affective human connectedness (in the case of sincerity). In so doing, the author identifies important evaluative differences between sincerity and honesty and provides a substantive explanation for how our lived presumption about the communicative truthfulness of others is possible.
