Book excerpt: Polycentric Governance and the Good Society: A Normative and Philosophical Investigation offers an examination of the idea of polycentric governance as one of the pillars of a flourishing human society. Rather than following the conventional path of suppressing complexity and diversity for the sake of reaching agreement on justice and political stability, David Thunder and Pablo Paniagua see complexity and diversity as assets that should be leveraged to make the "Open Society" a more prosperous, resilient, and flourishing place to live. Polycentric Governance and the Good Society provides valuable food for thought for academics and students looking for a probing, cross-disciplinary discussion of the ethos and institutions of liberal democracy under conditions of social pluralism. Although the volume includes diverse disciplinary lenses, such as public choice theory, MacIntyrean social theory, and constitutional law, the driving concern is to exhibit the potential advantages of polycentric approaches to governance and social coordination for constructing a feasible and morally attractive social order. This is the first extended academic work to explore in depth the advantages, not only from an economic and organizational standpoint but also from a broader ethical, sociological, and anthropological perspective, of polycentric governance arrangements.
