The distinctive feature of this book is its ingenious argumentative strategy: it takes on the political by developing a practice and a thought the authors call ‘polemicization’. They draw from the recent work of the political philosopher Jacques Rancière, for whom a polemic or disagreement does not refer to the case when one interlocutor says white and another black. Instead, it designates the conflict arising when, for example, both parties say white, yet each understands something different by whiteness. This situation forces the interlocutors to construe the scene of the validity of their claims, which is just another way of saying that the given or commonplace is never settled once and for all.The authors generalise the logic of this encounter and claim that disagreement is the very process through which objectivity is instituted. They develop the contours of polemicization and deepen its philosophical implications through a critical engagement with the work of leading contemporary theorists, such as Lefort, Schmitt, Laclau, Derrida.
