It is very common to assert that the advocates of the purely free market make one fundamental and shaky assumption: that all human beings are angels. In a society of angels, it is commonly agreed, such a program could “work,” but not in our fallible world. The chief difficulty with this criticism is that no libertarian—except possibly those under Tolstoyan influence—has ever made such an assumption. The advocates of the free market have not assumed a reformation of human nature, although they would certainly have no objection to such a reformation if it took place.

Probably the most common ethical criticism of the market economy is that it fails to achieve the goal of equality. Equality has been championed on various “economic” grounds, such as minimum social sacrifice or the diminishing marginal utility of money (see the chapter on taxation above). But in recent years economists have recognized that they cannot justify egalitarian-ism by economics, that they ultimately need an ethical basis for equality.

History deals with unique and unrepeatable events, with the irreversible flux of human affairs. A historical event cannot be described without reference to the persons involved and to the place and date of its occurrence. As far as a happening can be narrated without such a reference, it is not a historical event but a fact of the natural sciences. The report that Professor X on February 20, 1945, performed a certain experiment in his laboratory is an account of a historical event.

Aprioristic reasoning is purely conceptual and deductive. It cannot produce anything else but tautologies and analytic judgments. All its implications are logically derived from the premises and were already contained in them. Hence, according to a popular objection, it cannot add anything to our knowledge.

Praxeology deals with the actions of individual men. It is only in the further course of its inquiries that cognition of human cooperation is attained and social action is treated as a special case of the more universal category of human action as such.

No less than from the action of an individual praxeology begins its investigations from the individual action. It does not deal in vague terms with human action in general, but with concrete action which a definite man has performed at a definite date and at a definite place. But, of course, it does not concern itself with the accidental and environmental features of this action and with what distinguishes it from all other actions, but only with what is necessary and universal in its performance.

The content of human action, i.e., the ends aimed at and the means chosen and applied for the attainment of these ends, is determined by the personal qualities of every acting man. Individual man is the product of a long line of zoological evolution which has shaped his physiological inheritance. He is born the offspring and the heir of his ancestors, and the precipitate and sediment of all that his forefathers experienced are his biological patrimony. When he is born, he does not enter the world in general as such, but a definite environment.

The study of all the data of experience concerning human action is the scope of history. The historian collects and critically sifts all available documents. On the ground of this evidence he approaches his genuine task.

The task of the sciences of human action is the comprehension of the meaning and relevance of human action. They apply for this purpose two different epistemological procedures: conception and understanding. Conception is the mental tool of praxeology; understanding is the specific mental tool of history.

The cognition of praxeology is conceptual cognition. It refers to what is necessary in human action. It is cognition of universals and categories.

Some writers are astute enough to realize that the market economy is simply a resultant of individual valuations, and thus they see that, if they do not like the results, the fault lies with the valuations, not the economic system. Yet they proceed to advocate government intervention to correct the immorality of individual choices. If people are immoral enough to choose whiskey rather than milk, cosmetics rather than educational matter, then the State, they say, should step in and correct these choices.
