This handbook engages with the critical ordering of Schmitt’s writings, investing in the proper contextualization of his polycentric thought. More important than whether Schmitt’s positions and concepts are relevant in the twenty-first century is how to read Schmitt so as to grasp the original meanings of his many publications. The handbook intends to provoke debate about the relevance of his canon for thinking about the present. It argues that the motif of order is central to making sense of Schmitt’s contributions to law, the social sciences, and the humanities, as well as that his contributions to diverse disciplines constituted a trinity of thought. Schmitt’s political thought cannot be understood without reference to his legal and cultural thought; his legal thought was informed equally by his political and cultural thought; and his cultural thought contains important traces of his political and legal thought. This theoretical and substantive overlap was deliberate.
