7. Decision-making

There are fads and fashions in the treatment of scientific problems and in the terminology of the scientific language.

8. Confirmation and Refutability

In the natural sciences a theory can be maintained only if it is in agreement with experimentally established facts. This agreement was, up to a short time ago, considered as confirmation. Karl Popper, in 1935, in Logik und Forschung3  pointed out that facts cannot confirm a theory; they can only refute it.

9. The Examination of Praxeological Theorems

The epistemologist who starts his lucubrations from the analysis of the methods of the natural sciences and whom blinders prevent from perceiving anything beyond this field tells us merely that the natural sciences are the natural sciences and that what is not natural science is not natural science. About the sciences of human action he does not know anything, and therefore all that he utters about them is of no consequence.

Posner on Privacy

At a recent conference on cybercrime, Judge Richard Posner, a well-known federal appeals court judge and one of the founders of the “law and economics” movement, said that the needs of national security trump a supposed right to privacy. The NSA spying programs should be allowed to proceed unimpeded by the wishes of people to keep their private activities from the public.

8. Recent Writings on the Problems of Interventionism

In Germany, the classical country of interventionism, the need to deal seriously with an economic critique of inter­ventionism was scarcely felt. Interventionism came to power without a fight. It could ignore the science of eco­nomics created by Englishmen and Frenchmen. Friedrich List denounced it as being injurious to the interests of the German people. Among the few German economists, Thünen was scarcely known, Gossen completely unknown, and Hermann and Mangold without much influence. Men­ger was “eliminated” in the Methodenstreit.

7. The Historical and Practical Arguments for Interventionism

Put on the spot by economic criticism, the representatives of the Historical-Realistic School finally appeal to the “facts.” It cannot be denied, they assert, that all the theoreti­cally unsuitable interventions were actually made, and con­tinue to be made. We cannot believe, they contend, that economic practice did not notice this alleged unsuitabil­ity. But interventionist norms survived for hundreds of years, and since the decline of liberalism, the world is ruled again by interventionism.

6. The Doctrine of Intervention

To prescientific thinkers, a human society built on private property in the means of production seemed to be naturally chaotic. It received its order, so they thought, only from im­posed precepts of morality and law. Society can exist only if buyer and seller observe justice and fairness. Government must intervene in order to avoid the evil that flows from an arbitrary deviation from the “just price.” This opinion pre­vailed in all remarks on social life until the eighteenth century. It appeared for the last time in all its naiveté in the writings of the mercantilists.
