"Rationale Rekonstruktion als Methode politischer Theorie zwischen Gesellschaftskritik und empirischer Politikwissenschaft" [pdf] by Daniel Gaus
"Rational Reconstruction as a Method of Political Theory between Social Critique and Empirical Political Science".
"Current political theory applies the concept of reconstruction almost exclusively to methods of critique. Given this focus it is often overlooked that the concept of reconstruction also has important methodological implications regarding the empirical analysis of politics. This imbalance particularly applies to how Jürgen Habermas' discouse theory of democracy has been perceived in political theory. The aim of the article is two-fold. Firstly, it offers an interpretation of discourse theory as a contribution to a "reconstructive sociology of democracy" that goes beyond the mere purpose of critique. Secondly, it seeks to illustrate the added value of Habermas' method of rational reconstruction to the empirical analysis of politics."
