Michael Moehler’s Minimal Morality: A Multilevel Social Contract Theory makes important contributions to the social contract tradition, particularly in exploring how social contract theories can address challenges that arise from deep moral pluralism. Fundamentally, the work provides a multilevel account of morality, though simplified for presentation as a two-level view of morality. These two levels of morality differ significantly in their form and in their contexts of applicability. One level is that of ‘traditional morality’, involving a rich set of practices, (...) motivations and shared values common to many mainstream moral theories. For instance, John Rawls provides a version of traditional morality in the form of principles of justice grounded in a shared conception of society as a system of cooperation between free and equal citizens motivated by a sense of justice. The second level is that of ‘minimal morality’, for which the book is named. Minimal morality is grounded in purely prudential and instrumental reasoning, and thus does not rely upon any special moral commitments or motivations. This latter level of morality, Moehler argues, is particularly important for societies possessing extremely deep moral pluralism rather than the moral consensus necessary for traditional moral.
