ABSTRACT According to the safety account of knowledge, one knows that p only if one's belief could not easily have been false. The account is open to two different readings, which, in turn, give rise to a weak version and a strong version of the safety condition. In this paper, I argue that, if we opt for the weak version, then we are not able to account for why one's belief in a lottery proposition based on statistical evidence is true as a matter of luck. But, if we opt for the strong version, then we are not able to accommodate some cases of perceptual knowledge. Therefore, the safety account of knowledge is undermined jointly by the lottery case and perceptual knowledge.
