 Most of the action in the philosophy of language has been with definite descriptions, but indefinite descriptions have also generated a fair bit of attention—some of it mirroring the debates about definite descriptions. For example Chastain (1975), Donnellan (1978), Wilson (1978), and Fodor and Sag (1982), held that indefinite descriptions are ambiguous between referential and quantificational interpretations. That is to say, there are referential and quantificational uses of indefinite descriptions and these are a reflex of a genuine semantical ambiguity. The basic structure of their argument was the following. Referential uses of indefinites must be either a function of quantifier scope or a semantically referential indefinite determiner. Since indefinites with the relevant scopal properties would violate standard syntactic constraints, indefinites must in some cases be semantically referential.
