By accepting the above proposals for translating tenses it appears possible to achieve a very general account of the interpretation of Warlpiri adjoined clauses. Moreover, if the analysis is correct it would provide an interesting example of natural language generalizing across tenses and NPs, since what we would have is a single syntactic construction whose interpretation varied according to whether an NP or a tense were translated with a distinguished variable. These results thus serve to pose once again the question (...) of where precisely the common features of tenses and NPs reside. Recent work applying model-theoretic techniques to natural language semantics may well provide an answer. Thus in Dowty (1979) and Larson and Cooper (1980) NPs and tenses both denote the same sort of set-theoretic object, viz., sets of sets. Within generalized quantification theory this is just to say that both NPs and tenses denote quantifiers (cf. Barwise and Cooper, 1981, for much illuminating information on quantifiers and natural language). It may thus be possible to view the interpretation of Warlpiri adjoined clauses as a case of natural language generalizing across the semantic type of quantifiers. (shrink)
