According to the current view, the maintenance of sound monetary conditions is only possible with a 'credit balance of payments'. The confutation of this and related objections is implicit in the Quantity Theory and in Gresham's Law. The Quantity Theory shows that money can never permanently flow abroad from a country in which only metallic money is used (the 'purely metallic currency' of the Currency Principle). The tightness in the domestic market called forth by the efflux of part of the stock of money reduces the prices of commodities, and so restricts importation and encourages exportation, until there is once more enough money at home. The precious metals which perform the function of money are distributed among individuals, and consequently among separate countries, according to the extent and intensity of the demand of each for money. State intervention to assure to the community the necessary quantity of money by regulating its international movements is supererogatory.

Against what is stupid, nonsensical, erroneous, and evil, [classical] liberalism fights with the weapons of the mind, and not with brute force and repression.

A government always finds itself obliged to resort to inflationary measures when it cannot negotiate loans and dare not levy taxes, because it has reason to fear that it will forfeit approval of the policy it is following if it reveals too soon the financial and general economic consequences of that policy. Thus, inflation becomes the most important psychological resource of any economic policy whose consequences have to be concealed; and so in this sense it can be called an instrument of unpopular, i.e. of anti-democratic, policy, since by misleading public opinion it makes possible the continued existence of a system of government that would have no hope of the consent of the people if the circumstances were clearly laid before them. That is the political function of inflation. It explains why inflation has always been an important resource of policies of war and revolution and why we also find it in the service of socialism.

All index-number systems, so far as they are intended to have a greater significance for monetary theory than that of mere playing with figures, are based upon the idea of measuring the utility of a certain quantity of money. The object is to determine whether a gram of gold is more or less useful to-day than it was at a certain time in the past. As far as objective use-value is concerned, such an investigation may yield results. We may assume the fiction, if we like, that, say, a loaf of bread is always of the same utility in the objective sense, always comprises the same food value. It is not necessary for us to enter at all into whether this is permissible or not.

All Nazi champions insist again and again that Marxism and Bolshevism are the quintessence of the Jewish mind, and that it is the great historic mission of Nazism to root out this pest. It is true that this attitude did not prevent the German nationalists either from cooperating with the German communists in undermining the Weimar Republic, or from training their black guards in Russian artillery and aviation camps in the years 1923–1933, or— in the period from August 1939, until June 1941—from entering into a close political and military complicity with Soviet Russia. Nevertheless, public opinion supports the view that Nazism and Bolshevism are philosophies—Weltanschauungen—implacably opposed to each other.

All that the State need to do, and can do, in order to preserve the monetary system undisturbed, is to refrain from such intervention. That is the essence of the monetary theory of the classical economists and their immediate successors, the Currency School. It is possible to refine and amplify this doctrine with the aid of the modern subjective theory; but it is impossible to overthrow it, and impossible to put anything else in its place. Those who are able to forget it only show that they are unable to think as economists.

All varieties of the producers' policy are advocated on the ground of their alleged ability to raise the party members' standard of living. Protectionism and economic self-sufficiency, labor union pressure and compulsion, labor legislation, minimum wage rates, public spending, credit expansion, subsidies, and other makeshifts are always recommended by their advocates as the most suitable or the only means to increase the real income of the people for whose votes they canvass. Every contemporary statesman or politician invariably tells his voters: My program will make you as affluent as conditions may permit, while my adversaries' program will bring you want and misery.

Alterations in real prices occur slowly as a rule. But this stability of prices has its cause in the stability of the price-determinants, not in the Law of Price-determination itself. Prices change slowly because the subjective valuations of human beings change slowly. Human needs, and human opinions as to the suitability of goods for satisfying those needs, are no more liable to frequent and sudden changes than are the stocks of goods available for consumption, or the manner of their social distribution;

A metallic money, the augmentation or diminution of the quantity of metal available for which is independent of deliberate human intervention, is becoming the modern monetary ideal. The significance of adherence to a metallic-money system lies in the freedom of the value of money from State influence that such a system guarantees.
