Lars Vinx is an assistant professor in the Department of Philosophy at Bilkent University, Ankara, Turkey. His main areas of interest are legal and political theory, constitutional theory and the history of political thought.

'The debate between Kelsen and Schmitt is far richer and more timely than the foregoing brief overview can suggest. Vinx has provided a great service in executing a fluent and accessible translation, in writing an illuminating and erudite introduction, and in making the constitutional writings of Kelsen and Schmitt available to a wider audience than was previously the case. And Vinx has provided an additional service in reminding us that many of the important figures in the history of legal theory were also on the front lines of salient legal disputes offering arguments that put their theoretical positions in very concrete contexts.' Frederick Schauer, The New Rambler
