Safety and Unawareness of Error-Possibility

Abstract

Abstract In this paper, I first seek a relatively plausible formulation of the safety principle. To this end, I refute a recent form of safety by Duncan Pritchard and then defend another weaker form of safety as a necessary condition for knowledge. Second, and more importantly, I point out that this weaker safety is still insufficient, in that it neglects one’s belief regarding nearby error-possibilities—a factor that is largely omitted in the literature but could determine whether or not one knows. I then develop a safety-based account of knowledge that incorporates this element of belief concerning nearby error-possibilities. It is argued that such an account addresses various problematic cases and delivers useful resources for accommodating the phenomenon of knowledge-defeat, while preserving the important anti-skeptical power behind a safety principle.
