 As we have seen, several leading legal writers—be they in favour or against—continue to take Mill’s harm principle in original or modified form to be “the dominant theory as to what limits on criminal legislation should be observed by liberal democratic states” (Moore 2017: 461). Katrina Forrester’s post-war history of liberal political thought, however, emphatically puts John Rawls, rather than Mill, at the centre (Forrester 2021); and Piers Norris Turner, in an essay on Mill and modern liberalism, opines that public reason liberalism—whose leading light is Rawls—has become the dominant tradition within liberal thought “over the past three decades” (Turner 2017: 576; cf. Turner and Gaus 2017; Rawls 1999; Quong 2018; Hartley &amp; Watson 2018; Freeman 2020). However, the growing and highly sophisticated literature on public reason among specifically political philosophers has not yet—at least not to the extent that it has in relation to legal moralism and the harm principle—received the sustained study of writers as heavily steeped in the law as Feinberg, Hart or Devlin. Specific legal applications of the public reason approach are, however, already in existence (for example Flanders 2016) and the approach continues to develop.
