This is the only anthology that focuses exclusively on the two central issues in the philosophy of criminal law: (1) What kinds of behavior should society criminalize?; and (2) What should society do with those who engage in such behavior?

Ch. 1 defines activism as involving four judicial practices: refusing to take an attitude of deference for legislative or executive power or judgment; relaxing requirements for justiciability; breaking precedent; and loosely or controversially construing constitutions, statutes or precedents. I defend each element, through , in later chapters. I defend primarily in Ch. 2A-B, primarily in Ch. 2C, primarily in Ch. 3 and in Chs. 2 and 4. Ch. 1 concludes that - seem to have knowing change of the law in (...) common. Ch. 1 considers and rejects different definitions of activism. My definition explains what I call The Crossover Thesis, which says that two types of activism, and , are quite distinct, and what I call The Political Neutrality Thesis, which says activism and passivism are politically neutral in that neither is necessarily conservative or liberal, and neither is necessarily politically superior to the other. ;Ch. 2 defends activism against objections based on democracy by reconciling activism with democracy somewhat and by supporting some activism based on the Constitution's supreme legal authority. I give what I call The Ashwander Defense and the Carolene Defense of activism, which are named after famous judicial opinions I use to defend activism. ;Ch. 3 argues against stare decisis, which requires following precedent. The passivists' version of stare decisis is inadequately supported by arguments that stare decisis increases: the fairness of treating like cases alike; the predictability of the law; thereby the efficiency of judges in making decisions. ;Ch. 4 argues that courts should use due process more to support activism which clarifies the law. I show how much activism is justified by the vagueness doctrine, which constitutionally requires law's meaning to be reasonably accessible to ordinary people. ;Ch. 5 summarizes earlier chapters and shows how my defense of activism is restrained.
