Barbara Partee (2006), “Do We Need Two Basic Types?”

“…Carstairs-McCarthy argues that the apparently universal distinction in human languages between sentences and noun phrases cannot be assumed to be inevitable….His work suggests…that there is also no conceptual necessity for the distinction between basic types e and t….

If I am asked why we take e and t as the two basic semantic types, I am ready to acknowledge that it is in part because of tradition, and in part because doing so has worked well.…”

Some of Partee’s Suggested Ingredients for an Alternative

• eventish semantics for VPs: barked Bark(e, e’) & Past(e)

chase Chase(e, e’, e’’) • Heim/Kamp for indefinite NPs: a dog Dog(e)• entity/event neutrality, and

maybe predicate/sentence neutrality (cp. Tarski)

e . T e is (tenselessly) an event of John seeing Mary

T That is (tenselessly) an event of J seeing M

Tense may be needed (in matrix clauses). But does it do two semantic jobs: adding time information via the ‘e’-variable, like the adjunct ‘yesterday’; and closing the ‘e’ variable, as if tense is the 3rd argument of a verb that

can’t take a 3rd argument?

if T is (semantically) the verb’s 3rd argument, then why not…

Which expressions are of type <t>?

SENTENCES S = TP

T(P) / \

T V(P) past / \

D(P) V(P) John / \

V D(P) see Mary

e . T e is (tenselessly) an event of John seeing Mary

T e[PAST(e) & …]

<<e, t>, t> E . T e[PAST(e) & E(e) = T]

“God likes Fregean Semantics” theory of tense

(e < RefTime) & (RefTime = SpeechTime)

Which expressions are of type <t>?

Maybe None:

T(P) / \

T V(P) past / \

D(P) V(P) John / \

V D(P) see Mary

PastSeeingOfMaryByJohn(_)

a monadic predicate M can be “polarized” into a predicate +M that applies to e iff M applies to somethingor a predicate -M that applies to e iff M applies to nothing

+Polarized |

_ is such that [PastSeeingOfMaryByJohn(_)]

But what about Quantification?

<t> / \

<et, t> <et> / \ ran

<et, <et, t>> <et> every cow

Not at all clear that the “external argument” of ‘every cow’ is—or even can be—an expression of type <et>

We can discuss the difficulties for this kind of view in Q&A.But my point is not that an <et, t> analysis of quantifierscannot be preserved. My point is that there is no argument here for the standard typology, especially given doubts about <e>.

<<1, 0>, <<0, 1>><2, 2>

Human Quantification: Still Puzzling

But maybe…

• ‘every’ is a plural Dyad:EVERY(_, _) applies to <the Xs, the Ys> iff the Xs include the Ys

• ‘every cow’ is a plural Monad:[EVERY(_, _)^THE-COWS(_)]applies to the Xs iff the Xs include the cows

• ‘every cow ran’ is a plural Monad:[EVERY(_, _)^THE-COWS(_)]^RAN(_)applies to the Xs iff the Xs include the cows &

the Xs ran

iff the cows that are Xs outnumber the cows that

are not Xs

• ‘most cows ran’ is a plural Monad:[MOST(_, _)^THE-COWS(_)]^RAN(_) applies to

the Xs iff the cows that are Xs outnumber the other cows
