I concluded my survey of Part #11 of Adam Smith’s pamphlet “Additions and Corrections to the First and Second Editions of Dr. Adam Smith’s Inquiry into the Nature and Causes of the Wealth of Nations” (Smith 1784, pp. 13-22) in my previous post. Next up is Part #12 (pp. 23-47), where Smith adds an entirely new chapter to his great treatise: Chapter 8 of Book IV of The Wealth of Nations (“Conclusion of the Mercantile System”). As it happens, I surveyed that chapter earlier this year as part of my commemoration of the 250th anniversary of the publication of Smith’s second magnum opus. (See my blog post from 3 March 2026: “The true villains in The Wealth of Nations“.) Yet I now see that Smith added this particular chapter between 1778 and 1784, i.e. while he was a Commissioner of Scottish Customs and Salt Duties, so I will start from scratch and explore this chapter in far greater detail starting on Monday, 13 July.
