In Heuretics--he defines the word as the "branch of logic that treats the art of discovery or invention"--Ulmer sets forth new methods appropriate for conducting cultural studies research in an age of electronic hypermedia. Like his widely acclaimed Applied Grammatology and Teletheory, Ulmer's newest volume offers applications of theory of interest not only to scholars but also to those working at the intersection of text and technology. Part One presents a reading of the history of method in the context of grammatology, a reading based on more than two decades' experience in teaching the classics of method from Platos Phaedrus through Descartes's Discourse on Method to modernist vanguard manifestos. Part two applies the poetics of method to the invention of rhetoric for a new computer literacy.
