The Romantic Performative develops a new context and methodology for reading Romantic literature by exploring philosophies of language from the period 1785-1835. It reveals that the concept of the performative, debated by twentieth-century theorists from J. L. Austin to Judith Butler, has a much greater relevance for Romantic literature than has been realized, since Romantic philosophy of language was dominated by the idea that something happens when words are spoken. By presenting Romantic philosophy as a theory of the performative, and Romantic literature in terms of that theory, this book uncovers the historical roots of twentieth-century ideas about speech acts and performativity. Romantic linguistic philosophy already focused on the relationship between speaker and hearer, describing speech as an act that establishes both subjectivity and intersubjective relations and theorizing reality as a verbal construct. But Romantic theorists considered utterance, the context of utterance, and the positions and identities of speaker and hearer to be much more fluid and less stable than modern analytic philosophers tend to make them. Romantic theories of language therefore yield a definition of the Romantic performative as an utterance that creates an object in the world, instantiates the relationship between speaker and hearer, and even founds the subjectivity of the speaker in the moment when the utterance occurs.
