At the Speed of Light There is Only Illumination is a collection of re-evaluative essays that measure Marshall McLuhan and his critical and theoretical legacy. Each contribution works toward a larger critical mosaic that as a whole offers a new version of McLuhan as an intellectual adventurer and cultural icon, of his ideas as complex architecture and brilliant lines. John Moss and Linda Morra drew the collection's essays from a symposium on McLuhan held at the University of Ottawa in 2000. Given McLuhan's prominent status in many academic disciplines, the contributors reflect a multidisciplinary background. Each essay is unique in its approach. Whereas some are extraordinarily personal and anecdotal, others are intellectually and provocatively engaged with McLuhan's ideas and the manner in which these ideas have been appropriated in contemporary discourse.
