For this relation is involved not only with that of the magnitude of the store to the number, but with that of the magnitude of the store to the mind, of the population. Its proportion to their number, and the resulting worth of currency, are calculable; but its proportion to their will for labour is not. The worth of the piece of money which claims a given quantity of the store is, in exchange, less or greater according to the facility of obtaining the same quantity of the same thing without having recourse to the store.
