James Mill (1773-1836), the father of John Stuart Mill, defended commerce and the freedom to trade against its critics on the grounds that it was natural, greatly contributed to human happiness, and added to the amount of wealth in society.
…no arrangement of society, consistent with any tolerable degree of freedom and security, seems capable of preventing this wonderful agent [the disposition to accumulation] from adding something every year to the fund of production, from continually increasing the annual produce. As it is this gradual produce on which the happiness of the great body of the people depends, we may reflect with satisfaction and wonder on the strength of the principle on which it is secured; on the provision which is laid in the original laws of human nature for the well-being of the species!
About this Quotation:
James Mill, the father of John Stuart Mill, was an ardent defender of free trade and an opponent of the “sinister interests” which controlled British politics in the early 19th century. In this tract he defends the liberty and mutual benefits of free trade at a difficult time – Napoleon’s blocade of continental Europe was in force, in an attempt to weaken Britain by denying it its traditional markets on the mainland, and there existed a popular notion that trade and industry were not “really productive” whereas only “agriculture” was. So Mill had to fight a battle for free trade on two fronts: that England would benefit from free trade even if other countries persisted in subsidies and tariff protection; and that trade in goods other than traditional agricultural products could add to the sum total of “national wealth”. Even 200 years after Mill wrote this tract, we are still fighting the same battles.
