This chapter explores the overall significance of genius in the eighteenth and nineteenth centuries as it became associated with authorship, the fine arts, and nature in ways that helped produce a new form of cultural nationalism. The Romantic idea of genius supported new versions of both autonomous individualism and national identity, as readers identified through the genius of representative “great men” with the nation. Genius in this way simultaneously individuated and connected, playing a key role in the formation of national high cultures and canons as well as the overall creation of a liberal democratic social order. Beginning in the late eighteenth century, genius also became increasingly associated with wild and sublime nature, naturalizing these newly emerging forms of social identity and laying the groundwork for the landscape of genius.
