Following the established pattern of the series Minima, What Is Critique? comprises three texts. First is Foucault’s 1978 lecture “Qu’est-ce que la critique? (Critique et Aufklärung)”, which would be published as an article only twelve years later, accompanied by the ensuing discussion. The second text is “What Is Critique? An Essay on Foucault’s Virtue”, published in 2001, in which Judith Butler, in her inimitable and meticulous way, reads Foucault’s lecture. In the introduction to the two texts in relation to one another, Adriana Zaharijević and Predrag Krstić attempt to say what would be the virtue of critique, examining Foucault’s late interest in the Enlightenment and a post-Kantian understanding of critique as the practice and transgression of borders, bringing it into Butler’s discussion with Habermasian normativists.
