"The most rigorous attempt to construct a theory of the state of emergency can be found in the work of Carl Schmitt. The essentials of his theory can be found in Dictatorship, as well in Political Theology, published one year later. Because these two books, published in the early 1920s, set a paradigm that is not only contemporary, but may in fact find its true completion only today, it is necessary to give a resume of their fundamental theses. The objective of both these books is to inscribe the state of emergency into a legal context."
