to circumnavigate the world of books previously locked up in a pluralistic world of monastic cells. Boldness of type created boldness of expression. Uniformity reached also into areas of speech and writing, leading to a single tone and attitude to reader and subject spread throughout an entire composition. The "man of letters" was born. Extended to the spoken word, this literate equitone enabled literate people to maintain a single "high tone" in discourse that was quite devastating, and enabled nineteenth-century prose writers to assume moral qualities that few would now care to simulate. Permeation of the colloquial language with literate uniform qualities has flattened out educated speech till it is a very reasonable acoustic facsimile of the uniform and continuous visual effects of typography. From this technological effect follows the further fact that the humor, slang, and dramatic vigor of American-English speech are monopolies of the semi-literate. These typographical matters for many people are charged with controversial values. Yet in any approach to understanding print it is necessary to stand aside from the form in question if its typical pressure and life are to be observed. Those who panic now about the threat of the newer media and about the revolution we are forging, vaster in scope than that of Gutenberg, are obviously lacking in cool visual detachment and gratitude for that most potent gift bestowed on Western man by literacy and typography: his power to act without reaction or involvement. It is this kind of specialization by dissociation that has created Western power and efficiency. Without this dissociation of action from feeling and emotion people are hampered and hesitant. Print taught men to say, "Damn the torpedoes. Full steam ahead!"
