Pierre Elliott Trudeau. Marshall McLuhan. Two Canadian Catholic 20th-century public intellectuals whose lives and ideas intersected in surprising ways. This collection of their entire correspondence – from 1968 to 1980 – shines a light on their friendship and mutual respect during a fascinating period when television ruled and the world was becoming a global village. Annotated by scholar Elaine Kahn, who encountered the work of both these thinkers as a teenage student, the letters are a window on ideas and concepts that shaped the world we know today.Elaine Kahn
