Abstract

Traditional interpretations of legal doctrine have seen the actus reus and the mens rea as independent elements of a crime. Here it is argued that various puzzles surrounding the nature of intent and of attempt can be better addressed if we reject that idea. Following Williamson’s account of knowledge, it is suggested that the two are inseparable. The crime consists in the performance of an intentional act. It follows that an act has been performed and that the performer is in a certain mental state. But these cannot in general exist independently of each other.
