Essential McLuhan 354 method of perceiving process and pattern is by inventory of effects obtained by the comparison and contrast of developing situations. Beyond Exposition for Exploration Civilized, rationally educated people expect and prefer to have problems described and analyzed sequentially. They try to follow your argument to a conclusion. They expect the conclusion to be your point of view, illustrative of your values. In contrast to the method of exposition is the method of exploration. This begins by the admission of ignorance and difficulties. Such statement will tend to be a tentative groping. The blind man’s cane picks up the relation of things in his environment by the quality of resonance. His tapping tells him what objects are adjacent to his stick. If his stick were connected to any of these objects, he would be helpless so far as orientation was concerned. This is always the plight of the logical method. It is useless for exploration. Its very strength makes it irrelevant. “Proof” of sanity is available only to those discharged from mental institutions. “Seeing Them Off the Premises” It is difficult to make a mistake in logic, once the premises are granted. Psychologists report that madmen are rigorously logical, but their premises are irrelevant. The method of exploration seeks to discover adequate premises. This book does not question the structures existing in our world as much as the hidden premises that are supposed to support them. When the ground changes, the figures may disappear. The expository method of system presentation serves very well to package preconceptions. The exploratory method encounters surprise and discovery at every turn. Only dead processes can be packaged. BRIDGES ARE INTERVALS OF RESONANCE AS MUCH AS MEANS OF CONNECTION. LIKE ANY RESONATING INTERVAL, THEY TRANSFORM BOTH AREAS THEY TOUCH. The popular game of “bridge” originated in a major social breakdown. When suburbia was new, community was buried. “Bridge,” like booze, served as a ghostly paradigm of community. Bridges mark breakdowns in human communication. Every new slang phrase marks wit’s end. It is a frantically devised bridge over an unexpected break in the order of human perception. In “hardware” terms, it is obvious that where roads end, bridges begin. Confronting the wide diversity of breaks in the organization structures of our time, this book throws bridges across every kind of gap in our social fabric.
