Semantics & Pragmatics I: 5/2/19 Handout Szabolcsi 2010 §2; Jacobson 2014, §14 Dan Lassiter 1 Scope A generalized quantifier is (the characteristic function of) a set of properties. A quantified (declarative) sentence asserts that some property is in the GQ denoted by the widest-scope quantifier in the sentence. For example, (1) a. every dog barks ;g = 1 iff barks ;g every dog ;g J KM J ;gKM J KM b. every dog 3 loves his3 master = 1 iff Jx loves ;g master ;g x KMx every∈ dog ;g (bound his) [ J KM] J KM ;g J KM c. every dog 3 loves his4 master = 1 iff J{x S loves ;g[( master ;g)(g)](4KM)}x∈ every dog ;g (free his) d. every[ J dogKM chased] J someKM cat ;g = 1 iffJ K (wideM scope every dog) J{x S y cat ;g[( y chased)(KM(;g ))](y x )} ∈ every dog ;g e. everyJ dogK chasedM someJ catKM ;g = 1 iffJ K (wideM scope some cat) J{y S ∃x[ dog ;g( x) ∧ chasedKM (;g )(y )]}x ∈ some cat ;g J KM J KM J KM Scope is a{ propertyS ∀ [ of expressions,( ) → which is defined( )( in)]} terms∈ of the way that the denotation of the expression is semantically combined with the denotations of other expressions in the sentence. The scope of a quantificational DP, on a given analysis of the sentence, is that part of the sentence which denotes a property that is asserted to be an element of the generalized quantifier denoted by DP on that analysis. (Szabolcsi 2010: 10) In the examples in (1a)-(1d), the scope of the expression every dog is whatever linguistic material denotes the sets that are claimed to be in the GQ every dog ;g. J KM • In (1a) the scope of every dog is barks. • In (1b) and (1c) the scope of every dog is loves his master • In (1d) the scope of every dog is chased some cat. • In (1e) the scope of every dog is just chased. In (1e) some cat takes scope over every dog chased. Note that this holds regardless of your syntactic commitments: the idea that semantic scope is determined by syntactic hierarchy is a hypothesis (due to Reinhart) and is controversial in formal semantics. 1 2.3 Scope and constituent structure 13 chosen below will make the relation between Montague’s, May’s, and Hen- driks’s methods the most transparent. We start by applying the verb to arguments interpreted as free individual variables and build a sentence without quantifiers. Montague notated such variables with indexed pro- nouns in the syntactic derivation; we employ indexed empty categories ec. Properties (of type e, t )arethenformedfromthissentencebyabstract- ing over the variables! one" by one. Abstraction is achieved by binding the variable by a λ-operator.

The last step that introduces the universal is in (22): (21) Object > Subject reading (22) λQ y[man!(y) Q(y)](λx z[dragon!(z) spot !(x )(z)]) = ∀ → 3∃>1 ∧ 3 y[man!(y) λx z[dragon !(z) spot !(x )(z)](y)] = ∀ → 3∃>1 ∧ 3 y[man!(y) z[dragon !(z) spot !(y)(z)]] ∀ →∃>1 ∧ Montague’s PTQ collapsed the two steps of λ-binding a free variable 3and Quantifier applying lowering a generalized (not in quantifier Szabolcsi to2010 the) property so formed into a single rule of quantifying-in.

This approach is no longer used, for lots of reasons: e.g., even theorists who are otherwise free in their use of transformations generally don't like to make use of lowering operations. But it's not much different from Montague's more influential proposal, and: • It was presumably a major source of inspiration for May's (1977; 1985) influential Quantifier Raising proposal | though Lakoff and others who argued for this (McCawley, Lewis) are rarely cited in that tradition. (They were in the Bad Guys camp of the day.) • Semantically, the general form of the proposal is still what every theory of quantifier scope gives you: what varies in the two interpretations is the order in which the two variables are abstracted over, i.e., in how the syntax is supposed to create the required semantic structure. 4 Quantifier raising Interpretive semantics architecture (Jackendoff 1972; Chomsky 1976; May 1977; Heim & Kratzer 1998: etc.).
