VI. The Plenty or Scarcity of any Particular Thing, is the sole Cause when any Commodity or Thing can become higher or lower in Price; or, in other Words, as the Demand is greater or less in Proportion to the Quantity of any Thing, so will such Thing, whatsoever it is, be cheaper or dearer. Nor can any Arts or Laws make this otherwise, any more than Laws or Arts can alter the Nature of Things.
VII. All Things, that are in the World, are the Produce of the Ground originally; and thence must all Things be raised. The more Land therefore shall be improv'd and cultivated, etc. the greater will the Plenty of all things be, and the more People will it also imploy. And as the Produce will hence be increased, so will the Consumption of all Things increase too; and the greater the Plenty becomes this Way, the cheaper will every Thing be.
