Abstract

According to a version of Infallibilism, if one knows that p, then one’s evidence for p entails p. In her Fallibilism: Evidence and Knowledge, Jessica Brown has recently developed two arguments against Infalliblism, which can both be presented in the form of a dilemma. According to the first dilemma, the infallibilist can avoid scepticism only if she endorses the claim that if one knows that p then p is part of one’s evidence for p. But this seems to come at the cost of making infelicitous claims. According to the second dilemma, the infallibilist cannot make sense of the phenomenon of defeat unless she rejects closure. In this paper, we argue that the infallibilist has the conceptual tools to resist both dilemmas.
