Editors' introduction to the interview: Stephen Elstub articulates that deliberative democracy, as a theory, can be seen as having gone through various distinct generations. The first generation was a period where the normative values and the justifications for deliberative democracy were set out. This prompted criticism from difference democrats who saw the exclusion of other forms of communication by the reification of reason in deliberation as a serious shortcoming of the theory. This in part prompted the growth of the second generation of deliberative democracy, which began to focus more on the theory's operability. These theorizations, from the mostly 1990s and early 2000s, have led to the third generation of the theory—one embodied by the empirical turn. Elstub uses this genealogy as a foundation from which to argue that the current focus of deliberative democracy is on implementing deliberative systems rather than only deliberative institutions and this could potentially represent a fourth generation of deliberative democracy.
