Dougherty and Rysiew (2009) offer a different strategy for accounting for CKAs’ oddity while both protecting fallibilism and avoiding EC. While they grant that the latter portion of CKAs express epistemic possibility, they recommend thinking of what is epistemically possible for a subject in terms of those things which his evidence, rather than what he knows, does not rule out. (Dougherty and Rysiew take a person’s evidence, roughly, to be their basic data. While wishing to stay neutral as to just what comprises this, they deny the Williamsonian thesis (2000) that one’s evidence just is one’s knowledge.) On this view, CKAs express, as Lewis assumes, precisely the fallibilist idea. According to Dougherty and Rysiew, however, their oddity poses no problem for fallibilism, and so does not motivate EC, as that oddity can be explained pragmatically.
