 Horn has clearly identified two distinct and very general patterns of meaning and interpretation. Critics maintain, however, that Horn’s two principles provide no reason to expect the two indicated interpretations rather than those we do not observe (Lepore &amp; Stone 2015: §3.1; W. Davis 2016a: §4.7). They ask how Q can predict [11b] without predicting [10b], and how [10a] can be derivable from R if [11a] is not. What in R predicts [10a] rather than other strengthenings, such as “He broke someone else’s finger”?  [46]
