The property a man has in his own industry, is violated, whenever he is forbidden the free exercise of his faculties or talents, except insomuch as they would interfere with the rights of third parties.

Political economy has only become a science since it has been confined to the results of inductive investigation.

The entrepreneur shifts economic resources out of an area of lower and into an area of higher productivity and greater yield.

To a proprietor of a mine, the silver money is a produce with which he buys what he has occasion for. To all those through whose hands this silver afterwards passes, it is only the price of the produce which they themselves have raised by means of their property in land, their capitals, or their industry. In selling them they in the first place exchange them for money, and afterwards they exchange the money for articles of consumption.

All those who, since Adam Smith, have turned their attention to Political Economy, agree that in reality we do not buy articles of consumption with money, the circulating medium with which we pay for them. We must in the first instance have bought this money itself by the sale of our produce.

The theory of interest was wrapped in utter obscurity, until Hume and Smith dispelled the vapor.

Alas, how many have been persecuted for the wrong of having been right?
