Wrongs and Crimes is about the relationship between wrongs and crimes! It is about the nature and sources of wrongdoing, why wrongdoing can make a person liable to punishment. In the light of that it is about the scope of the criminal law. The book covers far too many issues – everything from the nature of wrongdoing, to debates about free will, to the nature of harm and the harm principle, to consent, inchoate wrongdoing, and firearms possession. As taster, I focus only on one issue that I address in chapter 5: can punishment be justified in the face of challenges from free-will sceptics?
