 Lewis argues that this model can make sense of a number of otherwise puzzling features of language. One notable example of this involves quantification. Most quantifiers we use do not range over the entire universe. We quantify only over a restricted range. Lewis says that it is the salient objects. He also says that this happens not just when we explicitly quantify, but also when we use terms that have a quantificational analysis. He mentions in passing that “knows” might be one such term.
