 (77) is ambiguous between one where ‘a book by Chomsky’ takes wide scope over ‘every man who reads’ and one where it takes narrow scope. Maybe so; but most quantifiers in fact cannot escape from relative clauses. Relative clauses are known as ‘scope islands’, or contexts in which quantifiers can’t be interpreted as raised. In fact, it has been noted that indefinites seem to escape from nearly any normal scope island whatsoever. This suggests that treating the various readings as an ambiguity akin to other scopal ambiguities is mistaken. Another treatment of (77)’s multiplicity of readings involves domain restriction: if we restrict the domain of ‘a book’ to only one particular book, we can emulate the reading one would get from treating ‘a book’ as having wide-scope. Domain restriction traditionally is treated as a matter of context sensitivity rather than ambiguity. We thus have some reason to doubt that the right treatment of (77) has much to do with the phenomenon of scope. (see Schwarzchild (2002) for further discussion).
