Abstract
Gideon Yaffe’s “subjectivism about attempts” rest on the Transfer Principle: “If a particular form of conduct is legitimately criminalized, then the attempt to engage in that form of conduct is also legitimately criminalized.” From the perspective of a moral concern with culpability, this principle seems to get to the heart of the matter: the true essence of what is wrong with attempting to commit a crime. Unfortunately, Yaffe’s argument for the Transfer Principle is based on an equivocation and therefore logically unsound. The moral core of the Principle is still sound, but we can’t tell from Yaffe’s book how far that principle would take us in the criminal law.
