This article defends Ernesto Laclau against the charge that his work, manifested most clearly in On Populist Reason, affirms an authoritarian politics to account for the genesis of collective identity. To outline this, I read Laclau’s thought through three logics – termed the logics of universal imposition, negation, and symbolic mediation – to argue that he rejects the first but adopts the latter two, with the logic of symbolic mediation being particularly important. Rather than unity resulting when distinct groups agree (...) over a positive meaning of a signifier or when it is imposed on them by an authoritarian leader, Laclau claims that unity depends upon the existence of empty signifiers that lack substantial meaning. Engaging with the structure and functioning of this lack, I utilize Laclau’s notion of ‘constitutive distortion’ to highlight an often overlooked structural component of his account that I call ‘misunderstanding’. Rather than a negative occurrence, misunderstanding is a fundamental and positive condition of collective identity because it permits the various groups to affirm different, even contradictory, positions regarding the meaning of empty signifiers (permitted by the fundamental lack of such signifiers), all the while (through the shared but mistaken belief that they agree over its meaning) binding each group into a collective identity. This misunderstanding, which must remain hidden from the participants of the collective identity, is a fundamental condition of the process through which collective identity is created and sustained because it permits the various groups to believe that they share a collective identity while maintaining the heterogeneity that is necessary, on Laclau's telling, for the continued existence of the collective.
