Whether with Kant or among conservatives, on the Internet, in environ- mental discourses or in Zanzibar: this book explains how norms emerge, why they are adopted, how they can be legitimated, and how they are con- tested and even disappear. Combining twelve contributions by 14 authors from a diverse disciplinary background, the book unites, for the first time, selected important younger voices of the Frankfurt School of Critical Normative Theory. The contributions show how transnational constella- tions, the flexibility of normative instruments, and the increasing variety of normative actors are proceduralized in diverse social spheres. Though evidencing differing degrees of bindingness, norms are shown to play a central role in regulating behaviour. These norms then form normative orders, with and through which political authority and the distribution of rights and goods are legitimized: in criminal law, in the upbringing of chil- dren in Islamic societies, in the territorial state, in the discourse on pro- gress, and in the Anthropocene.
