Niklas Luhmann elaborated his account of the political system in a complex, though often implicit, debate with Carl Schmitt. Underlying his systems-theoretical model of politics, and of the legitimacy of politics, is the anti-Schmittian view that modern society's communications about itself are neither coordinated by, nor embodied in, a political centre, and that politics is always an unemphatic aspect of these communications. However, this article proposes an immanent critique of Luhmann's analysis of the political system, and it argues that his (...) theory uses highly selective and puristic techniques to support its limitation of society's politics. If interpreted critically, in fact, Luhmann's political sociology illuminates the specific politicality and political emphasis of certain communications, it underlines the distinction of politics from other systems of social communication, and it calls for a re-insistence on the political as a primary category of social analysis.
