This chapter explores the critique of the rationality of political discourse in Søren Kierkegaard’s Two Ages. Kierkegaard argues that participants in the emerging newspaper public of the 1840s lack the passion to match their words with deeds. He can be credited with identifying a new separation between political speech and political action among participants in the mediated public sphere. Kierkegaard then attempts to unmask ulterior motives like envy and status competition that belie the surface-level rationality of mediated political discourse. The chapter aims to clarify the sense in which Kierkegaard is a critic of political rationalism, trace the limits of his critique, and argue for its continuing relevance today.
