 Unsurprisingly, the significance and value of Schmitt’s works is subject to heated controversy (Caldwell 2005). A group of authors sympathetic to Schmitt argue that Schmitt’s analysis of liberal constitutionalism during the Weimar period is separable from his support for National Socialism and that it constitutes an insightful and important analysis of the political presuppositions of a well-functioning liberal constitutional system (Bendersky 1983; Schwab 1989; Gottfried 1990; Kennedy 2004; Schupmann 2017). From the left, Schmitt’s work is sometimes taken to illustrate the affinities between a purely economic liberalism and political authoritarianism (Mauss 1980; Cristi 1998). The view that the Schmitt of the Weimar period can be read as a defender of liberal order has been questioned by authors who stress the continuity between Schmitt’s conceptions of law, sovereignty, and democracy and fascist ideology (Wolin 1992; Dyzenhaus 1997; Scheuerman 1999). However, engagement with Schmitt is nevertheless considered to be important. It has been argued that Rawlsian political liberalism is vulnerable to Schmitt’s critique of liberalism due to its unwillingness to base itself explicitly on a liberal conception of the good (Dyzenhaus 1997, 218–58) or due to its refusal to recognize the antagonistic nature of politics (Mouffe 1999b). Moreover, Schmitt’s views on sovereignty and emergency powers are often seen as the intellectual basis of contemporary calls for a strong executive power unhampered by constraints of legality (Dyzenhaus 2006, 35–54; Scheuerman 2006; Posner and Vermeule 2010, 3–24). Finally, there are an increasing number of authors who concentrate on particular arguments of Schmitt’s that are seen as worth developing in a systematic context. Two focal points of recent interest are Schmitt’s theory of popular sovereignty (Arato 1995; Lindahl 2007; Kalyvas 2008, 79–186; Loughlin 2010, 209–37; Kahn 2011; Colon-Rios 2012, 79–101; Minkkinen 2013; Vinx 2013a) and his conception of international order (Odysseos and Petito 2007; Slomp 2009; Legg 2011; Benhabib, 2012; Vinx 2013b; Hathaway and Shapiro 2017, chapter 10).
