Time pronouns and non-quantificational frame adverbials denote definite
pluralities
of times. This explains two otherwise puzzling properties of English
habitual sentences. First,
bare (unquantified) habituals display homogeneity effects (Ferreira 2005).
Second, they tolerate exceptions when those exceptions are irrelevant for
the current Question Under Discussion. We derive both homogeneity and
exception tolerance from the same general pragmatic principles used to
analyze plural definite descriptions, as in Križ (2016). The account
requires no specialized habitual operator, though it is compatible with
other work that does (e.g. Deo 2009). Homogeneity and exception tolerance
are direct consequences of general features of the pragmatics of plurals.
