Abstract

Canadian intellectual Marshall McLuhan left a controversial legacy. This dissertation addresses the four chief paradoxes that his work poses for contemporary commentators: the core meaning of his texts; the tradition in which his contribution now seems most intelligible; the divergent response to his work; and the enduring yet fragmentary impact of his contribution to popular and academic life. Taking a rhetoric of inquiry approach, modified by Gerald Holton's writing in the history of science, this reappraisal argues for McLuhan's significance as a theorist of communications as techno-cultural transformation or "mediamorphosis"; for his seminal role within the Toronto School of Communications; and for his inspiring relevance within the interdiscipline of communications, despite the forging of a negative academic consensus against his work in the early 1970s. McLuhan united the ancient arts of grammar and rhetoric into a techno-cultural hermeneutics that constitutes an unexhausted approach to the study of the impacts of media and technologies on sensibilities, literacies and culture
