  Things are yet more complicated. Inferential knowledge is defeasible, or, more precisely stated, what a subject takes to be inferential knowledge may turn out to be pseudo, non-genuine, a false cognition imitating a true one, or even in Gettier-style cases an accidentally true cognition masquerading as one genuinely inference-born. Knowledge has a social dimension. Not only would awareness of a counterexample be a defeater, but also if someone were to present a counterinference to a conclusion opposed to ours, no longer would we have inferential knowledge. Awareness of any of several kinds of “blocker” of “reflection” can undermine the generalization on which such reflection depends. There are potential preventers of inferential awareness, “defeaters,” bādhaka, leading to belief relinquishment by someone who has hitherto not noticed a counterexample or the like and who has thus drawn a conclusion erroneously.
