This essay argues for Walt Whitman's significance to contemporary democratic theory, neither as a theorist of moral or aesthetic individualism nor as a theorist of communitarian nationalism, but as a theorist of the democratic sublime. Whitman's account of “aesthetic democracy” emphasizes the affective and autopoetic dimensions of political life. For Whitman, popular attachment to democracy requires an aesthetic component, and he aimed to enact the required reconfiguration of popular sensibility through a poetic depiction of the people as themselves a sublimely poetic, world-making power. Through his poetic translation of the vox populi, Whitman hoped to engender a robustly transformative democratic politics. He found the resources for political regeneration in the poetics of everyday citizenship, in the democratic potentials of ordinary life.
