 There is a surprising number of further issues regarding EXT and SK. Some of these consist in lesser-known incompatibilism arguments. For instance, there is a kind of “inverted” memory argument suggesting that, if Burge’s self-verifying judgments count as bona fide self-knowledge, then one’s memory would be infallible in ways that it is obviously not (Goldberg 2000b). In addition, it is sometimes argued that EXT and SK preclude the standard analysis of epistemic possibility. (Ebbs 2003; 2011. But see McLaughlin 2004.)
