Media studies has been catching up with McLuhan over the last 50 years. These essays are drawn from themost productive quarter-century of his career (1952-1978), anddemonstrate his abiding interest in the materiality of mediation, from comic books to fashion, from technology to biology.Anchoring these essays are four meditations on the work of hisgreat predecessor, Harold adams innis, who first proposed thecentrality of mediation to every facet of our daily lives. McLuhan took this task literally; rejecting the specialist approachof academic study, he published in mainstream magazinessuch as Look and Harpers Bazaar on topics such as sexualityand the fashion industry, in each case bringing to these topics insights that remain startlinglyfresh. The essays offer a rare glimpse into a great mind as it works out the implications of theeffects of media not only on what we know but on how we are coming to understand our being.
