When the act of navigation was made, though England and Holland were not actually at war, the most violent animosity subsisted between the two nations. It had begun during the government of the long parliament, which first framed this act, and it broke out soon after in the Dutch wars, during that of the Protector and of Charles II. It is not impossible, therefore, that some of the regulations of this famous act may have proceeded from national animosity. They are as wise, however, as if they had all been dictated by the most deliberate wisdom.

The interest of a nation, in its commercial relations to foreign nations, is, like that of a merchant with regard to the different people with whom he deals, to buy as cheap, and to sell as dear as possible. But it will be most likely to buy cheap, when, by the most perfect freedom of trade, it encourages all nations to bring to it the goods which it has occasion to purchase; and, for the same reason, it will be most likely to sell dear, when its markets are thus filled with the greatest number of buyers.
