Powe considers the existence of a unique visionary tradition of Canadian humanism and argues that McLuhan and Frye represent fraught but complementary approaches to the study of literature and to the broader engagement with culture. Examining their eloquent but often acid responses to each other, Powe exposes the scholarly controversies and personal conflicts that erupted between them, and notably the great commonalities in their writing and biographies. Using interviews, letters, notebooks, and their published texts, Powe offers a new alchemy of their thought, in which he combines the philosophical hallmarks of McLuhan’s “The medium is the message” and Frye’s “the great code.”
