Abstract
What I wish to consider here is how understanding something is related to the justification of beliefs about what it means. Suppose, for instance, that S understands the name “Clinton” and has a justified belief that it names Clinton. How is S’s understanding related to that belief’s justification? Or suppose that S understands the sentence “Clinton is President”, or Jones’ assertive utterance of it, and has a justified belief that that sentence expresses the proposition that Clinton is President, or that Jones said that Clinton is President. How is S’s understanding related to the justifications of these beliefs?
