Reciprocity

Abstract

In chapter 4, I discussed a number of examples from the literature that were used to argue for the sets theory. The arguments all involved first finding a pair of noun phrases that in some models would be coreferent only on the union theory and then finding a predicate that in certain situations would appear to be true of one member of the pair and not the other. (235) below was an example considered in a model in which the young and old animals are just the cows and the pigs:

• a. The cows and the pigs were separated.

• b. The young animals and the old animals were separated.
