1. The increase in wealth and in the consumption of goods, and the diminution of the mortality rate. These are evidences of material progress.
2. The diffusion of culture, and "when it becomes possible to measure it," the productivity of men of genius. This is the measure of intellectual superiority.
3. Moral progress he would measure in terms of crime.
4. There remains the social and political organization, which he would measure in terms of the increase and decrease of individual liberty.
In all these attempts to measure the progress of the community the indices have invariably shown progression in some direction, retrogression in others.
From the point of view of social research the problem of progress is mainly one of getting devices that will measure all the different factors of progress and of estimating the relative value of different factors in the progress of the community.
