Title: Hurford Disjunctions without Entailment: A Mereological Approach
Time: Wednesday, April 29th, 1pm – 2pm
Location: 32-D461
 

Abstract: I present part of my ongoing work on Hurford disjunctions and the role of parthood in meaning. In the first part of the talk, I introduce novel data showing that predicates vary systematically in how they interact with the Hurford Constraint. In particular, I show that while all predicates give rise to infelicity in Hurford-like sentences, many can be rescued by inserting just or only in one of the disjuncts. This pattern resembles traditional scalar cases, but crucially arises even in the absence of an overt all in the other disjunct. I propose a typology that predicts when such rescue is possible: namely, in sentences containing predicates that universally quantify over parts of entities. More generally, I argue that all Hurford sentences can be rescued when universal quantification is introduced by some means, for instance via distribution over conjunction or through definite plurals.

Building on these examples, and on recent observations by Amir Anvari, I argue that Hurford disjunctions are best understood in terms of mereological constraints on quantificational domains, rather than entailment relations—entailment, on this view, emerges as a byproduct of parthood structure. In the second part of the talk, I sketch an account that captures these contrasts. The proposal combines a model without absolute atoms (following Magri 2008; and Sudo, 2025 (talk)) with a cognitively general no-overlap constraint on quantificational domains (Casati and Varzi, 1999; Chatain and McHugh, 2025; a.o.).
