The literary and scientific renaissance that struck Germany around 1800 is usually taken to be the cradle of contemporary humanism. Posthumanism in the Age of Humanism shows how figures like Immanuel Kant and Johann Wolfgang Goethe as well as scientists specializing in the emerging modern life and cognitive sciences not only established but also transgressed the boundaries of the "human." This period so broadly painted as humanist by proponents and detractors alike also grappled with ways of challenging some of humanism's most cherished assumptions: the dualisms, for example, between freedom and nature, science and art, matter and spirit, mind and body, and thereby also between the human and the nonhuman. Posthumanism is older than we think, and the so-called "humanists" of the late Enlightenment have much to offer our contemporary re-thinking of the human.

Improvisation as Art traces how modernity's emphasis on inventiveness has changed the meaning of improvisation; and how the ideals and laws that led improvisation to be banned from "high art" in the eighteenth century simultaneously enabled the inventive reintegration of improvisation into modernism. After an in-depth exploration of contemporary theoretical contentions surrounding improvisation, Landgraf examines how the new emphasis on inventiveness affects the understanding of improvisation in the emerging aesthetic and anthropological discourses of the late 18th and early 19th centuries. He first focuses on accounts of improvisational performances by Moritz, Goethe, and Fernow and reads them alongside the aesthetics of autonomy as it develops at the same time. In its second half, the book investigates how the problem of "planning" art receives a different treatment in German Romanticism. The final chapter focuses on the writings of Heinrich von Kleist where improvisation presents a central aesthetic principle. Kleist's figurations of improvisation recognize the anthropological predicament of the self in modern society and the social constraints that invite and often force individuals to improvise.
