Considered as a "Polis," or state, they will be poorer than they would have been otherwise: poorer by the withdrawal of what the sick man's labour would have produced in the interval. His friend may perhaps have toiled with an energy quickened by the enlarged need, but in the end his own land and property must have suffered by the withdrawal of so much of his time and thought from them; and the united property of the two men will be certainly less than it would have been if both had remained in health and activity.
But the relations in which they stand to each other are also widely altered. The sick man has not only pledged his labour for some years, but will probably have exhausted his own share of the accumulated stores, and will be in consequence for some time dependent on the other for food, which he can only "pay" or reward him for by yet more deeply pledging his own labour.
Supposing the written promises to be held entirely valid (among civilized nations their validity is secured by legal measures[33]), the person who had hitherto worked for both might now, if he chose, rest altogether, and pass his time in idleness, not only forcing his companion to redeem all the engagements he had already entered into, but exacting from him pledges for further labour, to an arbitrary amount, for what food he had to advance to him.
[33] The disputes which exist respecting the real nature of money arise more from the disputants examining its functions on different sides, than from any real dissent in their opinions. All money, properly so called, is an acknowledgment of debt; but as such, it may either be considered to represent the labour and property of the creditor, or the idleness and penury of the debtor. The intricacy of the question has been much increased by the (hitherto necessary) use of marketable commodities, such as gold, silver, salt, shells, etc., to give intrinsic value or security to currency; but the final and best definition of money is that it is a documentary promise ratified and guaranteed by the nation to give or find a certain quantity of labour on demand. A man's labour for a day is a better standard of value than a measure of any produce, because no produce ever maintains a consistent rate of productibility.
