Abstract

Against the contention of David Lewis Philosophy and Public Affairs 8, 235–240, that the Prisoner’s Dilemma is a Newcomb Problem, José Luis Bermúdez Analysis 73, 423–429, has urged that Lewis’s assimilation removes the very outcome scenarios that make the Dilemma so puzzling. I objected that this criticism of Lewis presupposes that the Dilemma is harder to resolve than Newcomb’s Problem, in effect challenging Bermúdez to justify this assumption. In his 2015 he takes up the challenge, arguing that while the former presents a problem of strategic choice the latter is problem of parametric choice. I argue here that appeal to the distinction between these two kinds of choice cannot sustain the rejection of Lewis’s view
