of emphasis that delivers many a telling touch to lagging social attention. However, in the very Hot Peace since the Second War, it is the highways of the mind that have been found inadequate. Many have felt dissatisfaction with our educational methods since Sputnik, in exactly the same spirit that many complained about the highways during the War of 1812. Now that man has extended his central nervous system by electric technology, the field of battle has shifted to mental image-making-and-breaking, both in war and in business. Until the electric age, higher education had been a privilege and a luxury for the leisured classes; today it has become a necessity for production and survival. Now, when information itself is the main traffic, the need for advanced knowledge presses on the spirits of the most routine-ridden minds. So sudden an upsurge of academic training into the marketplace has in it the quality of classical peripety or reversal, and the result has been a wild guffaw from the gallery and the campus. The hilarity, however, will die down as the Executive Suites are taken over by the Ph.D.s. For an insight into the ways in which the acceleration of wheel and road and paper rescramble population and settlement patterns, let us glance at some instances provided by Oscar Handlin in his study Boston's Immigrants. In I 790, he tells us, Boston was a compact unit with all workers and traders living in sight of each other, so that there was no tendency to section residential areas on a class basis: "But as the town grew, as the outlying districts became more accessible, the people spread out and at the same time were localized in distinctive areas." That one sentence capsulates the theme of this chapter. The sentence can be generalized to include the art of writing: "As knowledge was spread out visually and as it became more accessible in alphabetic form, it was localized and divided into specialties." Up to the point just short of electrification, increase of speed produces division of function, and of social classes, and of knowledge.
