BOOK »The Noumenal Republic: Critical Constructivism After Kant«

Rainer Forst's latest volume was recently published in English translation by Polity. It is entitled “The Noumenal Republic: Critical Constructivism After Kant” and is available for free download with Open Access. In this book, Forst develops a critical theory after Kant, based on the assumption that all people are born with equal dignity and equal rights. This statement appears to be both normatively irrefutable and empirically incorrect; reality disproves it anew every day - and thus confirms its significance. The truth of this principle can be clarified philosophically by referring back to Kant's idea of a “noumenal republic”, in which every person is subject to the general law, which they also co-construct as legislators. A critical analysis of society and politics must show the extent to which reality makes a mockery of this. Forst's critical theory aims to prevent these perspectives from falling apart into a distant ideal and a diagnosis of hopelessness.

RESEARCH PAPER »The rational critique of social unreason. On critical theory in the Frankfurt tradition«

A new article by Rainer Forst was recently published in Constellations. It is entitled "The rational critique of social unreason. On critical theory in the Frankfurt tradition" and deals with the concepts of reason and unreason in the critical theory of the Frankfurt School. Forst argues that the Frankfurt School is characterised by a reflexive, systematic rational critique of existing forms of social unreason, combining social scientific analysis with normative reflection. A convincing continuation of this critical project should thus relate to the practice of justification, and thus ultimately to the principle of critique itself.

RESEARCH PAPER »The rule of unreason. Analyzing (anti-)democratic regression«

A new research paper by Rainer Forst has recently been published in Constellations. It is entitled "The rule of unreason. Analyzing (anti-)democratic regression" and deals with the notion of democratic or anti-democratic regression as part of an analysis of the crisis of democracy. The paper discusses the normative presuppositions that justify the use of this term, understood as a diagnosis of the 'rule of unreason'. This clarification allows to avoid some mistakes in the discussion on this matter: that of the status quo ante fixation, that of the reduction of the concept of democracy, and that of the wrong classification of the critique of democracy. Following these considerations, Forst discusses his own assessment of the causes of democratic regression and the paradoxes of our time.
