ABSTRACT
In order to understand the operation of political and economic forces, it is useful to imitate the practice of the physicist, and study each separate force in an artificial isolation. What actually happens is not, of course, what would happen if only one force were acting, but is a resultant of the effects of them all. The problem of calculating this resultant is, however, greatly simplified by the previous investigation of the tendencies of the various single forces. The effects of nationalism in isolation are too obvious to need study, but the effects of industrialism, in so far as its action is not thwarted or complicated by other factors, are less obvious, though certainly not less important if we wish to understand the modern world. Something has already been said on this subject in dealing with the causes of the present chaos, but then our discussion was merely incidental, and now it must be taken up on its own account.
