Book excerpt: The central concern of these eight studies and essays is the understanding and critique of culture at the shifty boundaries between the Modem and the Postmodern epochs. The author contends that what needs to be addressed is the very abyss, the "spacetime" between the Modern and the Postmodern worldviews, as well as the tension between aesthetics and ethics, critical discourse and the creative arts, in an effort to rethink multireferential processes of signification. The keystone of the book is Carravetta's notion of Diaphoristics, a theory of interpretation as dialogue. Diaphora, or difference, refers to the ancient quarrel between poetry and philosophy and signifies the movement between asymmetrical or heterogeneous forms of discourse that have, both historically and speculatively, borne the transfer of meaning from one semantic/hermeneutic field to another. The author focuses on the necessary risk and duplicity of criticism and develops nonagonistic models based on figuration and rhetorical dynamics. In two other chapters, the author steps back to reassess, in terms of the diaphora, the diverging notions of Postmodernity by the continental philosophers Lyotard and Vattimo. The collection ends with an essay on the long-overdue conversation between Vico and Heidegger.
