 A crucial question for guidance normativism concerns the distinction between rule guided and merely regular behavior. As Quine classically noted, on pain of vicious regress, meaning determining rules or conventions cannot be explicitly and deliberately adopted; they must somehow be “implicit” in the behavior of speakers. But then, Quine argued, we risk depriving the notion of a linguistic rule “of any explanatory force and reducing it to an idle label” (Quine 1935 [1976: 106]). We shall look at this issue in the next section.
