ABSTRACT
This transition is a very gradual one, and therefore difficult to discern, unless situations separated by a considerable distance in time or difference in development are compared with each other. This can be done in two ways, viz. by comparing the contemporary European situation with, say, the situation in the middle of the nineteenth century; or by comparing the present European situation with the present American situation. The former comparison is obviously more correct, but the latter comparison enhances the possibility of prediction.
