 Dretske suggested another reason for ruling out knowledge of limiting/elusive claims. He thought we can know banal facts (e.g., we ate breakfast) without knowing limiting/elusive claims they entail (e.g., the past is real) so long as those limiting/elusive claims are true, but we cannot then turn around and employ the former as our basis for knowing the latter. Suppose we take ourselves to know some claim, q, by inferring it from another claim, p, which we know, but our knowing p in the first place depends on the truth of q. Call this pseudocircular reasoning. According to Dretske, pseudocircular reasoning is unacceptable, and yet it is precisely what we rely on when we attempt to know limiting/elusive claims such as denials of skeptical hypotheses by deducing them from ordinary knowledge claims that entail them: we will not know the latter in the first place unless the former are true. The problem Dretske here raised was pressed earlier by critics of broadly reliabilist accounts of knowledge, such as Richard Fumerton (1995, 178). Jonathan Vogel (2000) discusses it under the heading bootstrapping, the procedure employed when, e.g., someone who has no initial evidence about the reliability of a gas gauge, comes to believe p on several different occasions because the gauge indicates p, and thereby knows p according to reliabilist accounts of knowledge, then infers that the gauge is reliable, by induction. By bootstrapping we may move—illegitimately, according to Vogel—from beliefs formed through a reliable process to the knowledge that those beliefs were arrived at through a reliable process. One may know p using a gauge in the first instance only if that gauge is reliable; hence, to conclude it is reliable solely on the basis of its track record involves pseudocircular reasoning.
