Speaker: Guillaume Thomas
Title: Incremental comparatives
Time: Thurs 4/16, 12:30-1:45
Place: 32-D461
In this talk I will investigate a form of comparison of superiority that one
could call `incremental', as in (1) and (2):
(1) Give me (some) more coffee.(2) Five customers bought a laptop yesterday, and one more customer bought a
desktop this morning.In its incremental reading, the request in (1) is satisfied even if the quantity
of coffee that I receive is less than the quantity of coffee that I got
before. In the same way, (2) is true even in case only one customer bought a
computer this morning. Incremental readings are not attested with all
predicates under all conditions, cf. (3) and (4):(3) Bob was happy right after the talk, and he is going to be happier tonight at
the party.(4) The temperature rose by 4C yesterday afternoon, and it's going to rise some
more this afternoon.(3) entails that Bob will be happier at the party than he was right after the
talk — hence, no incremental reading is available. (4) has an incremental
reading according to which the temperature might rise by less than 4C this
afternoon. And it might even be the case that the temperature fell down during
the night, and rose back again before now. However, it has to be the case that
the temperature rises from the degree it had reached yesterday afternoon — not
from a lower degree. A proper analysis of incremental comparison must capture
these restrictions on the availability of incremental readings.It will be argued that incremental comparison arises from the use of a specific
incremental comparison operator. Lexical ambiguity is supported by the absence
of incremental comparison in languages that do not lack standard comparison of
superiority (eg. German). The incremental comparison operator combines with a
property G of eventualities and degrees, and asserts that G is satisfied by an
eventuality E to some degree D. It also introduces a presupposition that a
specific eventuality E' that is associated with a degree D' precedes E, such
that G is satisfied by the sum of E and E', to the degree D plus D'. In other
words, the incremental comparison operator asserts that G(E)(D) is true and
presupposes that D increments a previous degree D' associated with a previous
eventuality E'. It is argued that the reference to a sum of eventualities E+E'
in the presupposition suffices to rule out unattested/limited incremental
readings with examples such as (3) and (4).
