But it was only the beginning: the effects of the introduction of gunpowder, the compass, the printing-press and paper, and the new ideas about the heavens, and the opening-up of relatively uninhabited lands, were scarcely discernible for two centuries, and then only as a destructive force. Indeed, for still another hundred years the process was one chiefly of disintegration. There was taking place a transference of power from the few to the many; a diffusion of sovereignty, as well as a redistribution of wealth; and the change was accompanied by an awakening of the masses to the meaning of the transformation which they were undergoing. The people began to realize that the invention of gun-powder had raised the peasant as a fighter to the level of the armed knight; that the compass and the opening-up of the Western hemisphere made it possible for the poor to escape from European masters whom they were unable to vanquish; and that the cheapness of books was linking the minds of the masses to the sources of learning and of religious tradition. It cannot but excite our mystic wonder that for nearly one hundred thousand years every new mastery of man over physical Nature was such that it inevitably played into the hands of rulers by strengthening their monopoly of initiative; and that then, at last, and ever since the fifteenth century after Christ, each new mechanical invention or discovery has had the unintended and undesired effect ultimately of scattering among the many the pent-up power of owners and rulers, and of creating in the many fresh psychic energy and a new capacity of invention.
