This chapter will examine the extent to which it is possible to re-frame our approaches to thinking about criminal justice in line with the perspective of positive criminology (and its ‘older sister’ positive psychology). Focusing in particular on debates about the rehabilitation of ‘offenders’ as a key purpose of criminal sanctions, it asks whether we can frame such activities as actively productive of some social good(s), as opposed to being concerned merely with the minimization of social harm(s). If so, what exactly are these goods, and what are the implications of recognizing them for how we do justice?
