Homogeneity as presuppositional exhaustification

Abstract The goal of this paper is to reconcile two observations regarding homogeneity and non-maximality. First, homogeneity is sensitive to constraints on presupposition accommodation, both in the positive case and under negation (Wehbe 2022). Second, there are asymmetries between positive and negative sentences with definite plurals (Bar-Lev 2021). We argue that taken together, these two observations support an account of homogeneity in terms of presuppositional exhaustification.
