 Other replies to the defeasibility argument include the denial of premise  (2),[65]  the denial of (4) (McDowell 1982, Kern 2006 [2017]), and the claim that the context-sensitivity of “knows” means that (4) is true only relative to contexts in which the possibility of future defeaters is relevant (see Neta 2002). But neither of these replies has yet received widespread assent.
