No scientist ever believes that he has the final answer or the ultimate truth on anything. - Carroll Quigley

After years of work in both areas of study, I concluded that the social sciences were different, in many important ways, from the natural sciences, but that the same scientific methods were applicable in both areas, and, indeed, that no very useful work could be done in either area except by scientific methods.

...another cause of today’s instability is that we now have a society in America, Europe and much of the world which is totally dominated by the two elements of sovereignty that are not included in the state structure: control of credit and banking, and the corporation. These are free of political controls and social responsibility and have largely monopolized power in Western Civilization and in American society. They are ruthlessly going forward to eliminate land, labor, entrepreneurial-managerial skills, and everything else the economists once told us were the chief elements of production. The only element of production they are concerned with is the one they can control: capital.

The social sciences are usually concerned with groups of persons rather than individual persons. The behavior of individuals, being free, is unpredictable.
