The older theories, which started from an erroneous conception of the social demand for money, could never arrive at a solution of this problem. Their sole contribution is limited to paraphrases of the proposition that an increase in the stock of money at the disposal of the community while the demand for it rClnains the same decreases the objective exchange-value of money, and that an increase of the demand with a constant available stock has the contrary effect, and so on. By a flash of genius, the formulators of the Quantity Theory had already recognized this. We cannot by any means call it an advance when the formula giving the amount of the demand for money (Volume of Transactions + Velocity of Circulation) was reduced to its elements.
