Labour, like all other things which are purchased and sold... has its natural and its market price.

I have already expressed my opinion on this subject in treating of rent, and have now only further to add, that rent is a creation of value, as I understand that word, but not a creation of wealth.

Possessing utility, commodities derive their exchangeable value from two sources: from their scarcity, and from the quantity of labour required to obtain them.

There can be no greater error then in supposing that capital is increased by non-consumption.

The demand for money is regulated entirely by its value, and its value by its quantity.

To alter the money value of commodities, by altering the value of money, and yet to raise the same money amount by taxes, is then undoubtedly to increase the burthens of society.

No extension of foreign trade will immediately increase the amount of value in a country, although it will very powerfully contribute to increase the mass of commodities and therefore the sum of enjoyments.
