Timothy Williamson, Duncan Pritchard, and Ernest Sosa are the foremost defenders of safety. According to these authors an agent S knows a true proposition P only if S could not easily have falsely believed P. Disagreement arises, however, with respect to how they capture the notion of a safe belief. Unlike Pritchard and Sosa, who have gone on to incorporate the safety condition into a virtue account of knowledge, Williamson distances himself from the project of offering reductive analyses of knowledge. Williamson’s project can best be thought of as an illumination of the structural features of knowledge by way of safety. The maneuvers of Pritchard and Sosa into the domain of virtue epistemology are not discussed here. This article is a treatment of the different presentations and defenses of the safety condition for knowledge. Special attention is first p
