ABSTRACT
In two fields, those of economic and military affairs, the nineteenth century saw change of such gigantic proportions as to make previous advance dwindle into insignificance. We deal here not only with this, but also with the introduction of a new dynamism which in our century is threatening to consume us-the stillevolving economy and military have clearly become cancerous. We shall see that at the beginning the outlook was very different. We take the revolution in the economy first.
