This chapter has two parts. In the first part, we convey to the reader the basic points we advocated in our previous book, Crime and Culpability: A Theory of Criminal Law. Those were: a focus on the actor’s assessment of the risks of various harms from the contemplated act and the reasons that exist that might justify or militate against the act; a single crime and a single form of culpability as opposed to multiple crimes and forms of culpability; the irrelevance of the act’s results; the nonculpability of negligence; the abolishment of incomplete attempts and other preparatory acts; and that the duration of acts affects their culpability. The second part of the chapter is a roadmap of the remaining chapters.
