In "Heuretics" - a word defined as "the branch of logic that treats the art of discovery or invention" - Ulmer sets forth methods appropriate for conducting cultural studies research in an age of electronic hypermedia. Like his works "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 1 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 Plato's "Phaedrus" through Descartes's "Discourse on Method" to modernist vanguard manifestoes. Part 2 applies the poetics of method to the invention of a rhetoric for a new computer literacy.
