Abstract
It is widely agreed that the top three Model Penal Code culpability levels suffice for criminal liability, but the fourth is controversial. And it isn’t just the particular MPC wording; that negligence should be on the list at all is controversial. My question is: What makes negligence so different? What is it about negligence that gives rise to the view that it should not suffice for criminal liability? In addressing it, I draw attention to how we conduct the debate, and how our framing of the issues is shaping it. My hope is to prompt thought and discussion on just what we want the element of mens rea to provide, and to draw attention to background assumptions that shape our views of what it should take for negligence to count as a species of mens rea.
