Abstract
In this chapter, Sifferd analyzes the grounds for moral and legal desert. She bridges the gap between compatibilist accounts of our moral and legal responsibility, and she argues that neither moral nor criminal responsibility demand impossible or superhuman abilities. Sifferd’s capacitarian view of agency embraces our mechanistic natures yet can still ground robust mental causation, a key requirement for criminal culpability. She also notes the ways in which the capacity for reasons-responsiveness is developed and maintained over time, and she claims that diachronic agency can instantiate meaningful self-control and self-formation with moral and legal rules in mind. Sifferd concludes that rapists do in some cases deserve criminal punishment. Her ultimate position is that basic desert is necessary but not sufficient for criminal punishment of rape.
