The objective exchange-value of money which rules in the market to-day is derived from yesterday's under the influence of the subjective valuations of the individuals frequenting the market, just as yesterday's in its turn was derived under the influence of subjective valuations from the objective exchange-value possessed by the money the day before yesterday. If in this way we continually go farther and farther back we must eventually arrive at a point where we no longer find any component in the objectIve exchange-value of money that arises from valuations based on the function of money as a common medium of exchange; where the value of money is nothing other than the value of an object that is useful in some other way than as money.
