Chapter 2 relies upon descriptions of what jurors found not to be felonious to draw conclusions about the meaning of felony in the medieval English legal context. Perhaps because the law was not heavily theorized, or perhaps because these are complex matters with which we still struggle in modern jurisprudence, medieval English felony law was tested by particular circumstantial elements that made a simple guilt or innocence determination difficult for jurors to reach. The chapter’s discussion of the paradigm of felony relies primarily on analysis of the categories of accident, self-defense, insanity, infancy, and duress. This paradigm, unmistakably influenced by notions of mind rather than reflecting a mere category of criminal acts, might be summarized as follows: a crime involving deliberation and rationality, the exercise of a person’s will in the absence of countervailing necessity, and an act that was wrongful and perhaps essentially wicked. Surely not all felonies fit this paradigm, but a pattern does emerge from a close reading of the plea rolls alongside literary texts.
