Various schools of thought parading under the pompous names of philosophy of law and political science indulge in futile and empty [p. 720] brooding over the delimitation of the functions of government. Starting from purely arbitrary assumptions concerning allegedly eternal and absolute values and perennial justice, they arrogate to themselves the office of the supreme judge of earthly affairs. They misconstrue their own arbitrary value judgments derived from intuition as the voice of the Almighty or of the nature of things.

According to a widespread opinion it is possible, even in the absence of government interference with business, to divert the operation of the market economy from those lines along which it would develop if left to exclusive control by the profit motive. Advocates of a social reform to be accomplished by compliance with the principles of Christianity or with the demands of “true” morality maintain that conscience should also guide well-intentioned people in their dealings on the market.

In eighteenth-century France the saying laissez faire, laissez passer was the formula into which some of the champions of the cause of liberty compressed their program. Their aim was the establishment of the unhampered market society. In order to attain this end they advocated the abolition of all laws preventing more industrious and more efficient people from outdoing less industrious and less efficient competitors and restricting the mobility of commodities and of men. It was this that the famous maxim was designed to express.

In investigating the economic problems of interventionism we do not have to deal with those actions of the government whose aim it is to influence immediately the consumer’s choice of consumers’ goods. Every act of government interference with business must indirectly affect consumption. As the government’s interference alters the market data, it must also alter the valuations and the conduct of the consumers.

The director wants to build a house. Now, there are many methods that can be resorted to. Each of them offers, from the point of view of the director, certain advantages and disadvantages with regard to the utilization of the future building, and results in a different duration of the building’s serviceableness; each of them requires other expenditures of building materials and labor and absorbs other periods of production. Which method should the director choose? He cannot reduce to a common denominator the items of various materials and various kinds of labor to be expended.

For more than a hundred years the substitution of socialist planning for private enterprise has been the main political issue. Thousands and thousands of books have been published for and against the communist plans. No other subject has been more eagerly discussed in private circles, in the press, in public gatherings, in the meetings of learned societies, in election campaigns, and in parliaments. Wars have been fought and rivers of blood have been shed for the cause of socialism. Yet in all these years the essential question has not been raised.

The socialist tracts deal with everything except the essential and unique problem of socialism, viz., economic calculation. It is only in the last years that socialist writers have no longer been able to avoid paying attention to this primordial matter. They have begun to suspect that the Marxian technique of smearing “bourgeois” economics is not a sufficient method for the realization of the socialist utopia. They have tried to substitute a theory of socialism for the scurrilous Hegelian metaphysics of the Marxian doctrine.

The entrepreneurs and capitalists do not have advance assurance about whether their plans are the most appropriate solution for the allocation of factors of production to the various branches of industry. It is only later experience that shows them after the event whether they were right or wrong in their enterprises and investments. The method they apply is the method of trial and error. Why, say some socialists, should not the socialist director resort to the same method?

The distinctive mark of socialism is the oneness and indivisibility of the will directing all production activities within the whole social [p. 706] system.
