 In many domains, however, theorists have found it useful to divide the phenomenon of ambiguity from other phenomena (e.g., underspecification, vagueness, context sensitivity). Ambiguity is of interest to philosophers for a variety of reasons, some of which we will look at below. First, ambiguity makes vivid some of the differences between formal languages and natural languages and presents demands on the usage of the former to provide representations of the latter. Second, ambiguity can have a deleterious effect on our ability to determine the validity of arguments in natural language on account of possible equivocation. Third, ambiguity in art can intentionally (or unintentionally) increase the interest in a work of art by refusing to allow easy categorization and interpretation. Fourth, ambiguity in the statement of the law can undermine their applicability and our ability to obey them. Finally, ambiguity resolution is an important feature of our cognitive understanding and interpretative abilities. Studying ambiguity and how we resolve it in practice can give us insight into both thought and interpretation.
