"She knows it" can vary with DeRose, in my understanding that the the standards must remain low, in ordinary conversational contexts. DeRose appears to base his argument purely in mirroring the skeptic strategy, which does make a satisfying point, however seems to be constrained based on how it is tailor-made for the skeptical argument. It is constrained in the sense that higher positive epistemic standard are not addressed, or fully elaborated, as he emphasizes low standards in reaction to the skeptical arguments. A person in a low epistemic condition would be accepted in saying he knows B, whereas the same person in a high epistemic standard position would be incorrect in saying he knows B.

To DeRose, it is matter of the sensitivity of the argument, which still appears ambiguous (although seems to rely heavily on spatio-temporal contexts, beyond this it still seems elusive). His truth-conditions of knowledge ascriptions appeal to the implicit sensitivity to the context. Lewis, like DeRose emphasizes language , however Lewis' Rule of Accommodation cannot explain a rise in epistemic standards when an expert claims to know, or in distinguishing the AI skeptic from the simple skeptic. As this rule operates on suggestion, does the suggestion itself in raising epistemic standards defeat Lewis's argument against the skeptics? (I am trying to read into what DeRose was saying about Lewis.)
