The Lottery Puzzle and Pritchard’s Safety Analysis of Knowledge

the safety analysis of knowledge, due to Duncan Pritchard, has it that for all contingent propositions, p, s knows that p iff s believes that p, p is true, and (the "safety principle") in most nearby worlds in which s forms his belief in the same way as in the actual world, s believes that p only if p is true. among the other virtues claimed by Pritchard for this view is its supposed ability to solve a version of the lottery puzzle. in this paper, i argue that the safety analysis of knowledge in fact fails to solve the lottery puzzle. i also argue that a revised ver - sion of the safety principle recently put forward by Pritchard fares no better.
