The late Wayne Constantineau was a mime and scholar who left behind him, at his death in 2006, his studies on mime and the insights of Marshall McLuhan. Eric McLuhan, who is bringing these studies to fruition in The Human Equation Toolkit, is also the author of Laws of Media (written with Marshall McLuhan), Electric Language, and The Role of Thunder in Finnegans Wake. He is also the editor of several collections of his father's work.

The second of five books in the groundbreaking new series The Human Equation Toolkit.
In Book 1 of The Human Equation Toolkit series, mime Wayne Constantineau and scholar Eric McLuhan explore the four positions of humans -- standing, lying down, sitting, and kneeling -- as the basis of all developments in culture, science, activity, and media. Now, in Book 2 of the series, they "do the math," giving us a generic equation for reconciling pairs of opposites by emphasizing differences, and for unifying diverse elements by stressing sameness -- creating a tool for investigating and transcending human development.
