The third book is sort of a revisitation of the subject matter of the book I recommended a year or two ago called “Guns, Germs, and Steel,” which was a physiologist’s view of the economic history of man. And it was a wonderful book.

And much of that same territory has now been covered by an emeritus history professor from Harvard, who just knows way more economics and science than is common for a history professor. And that gives him better insight.

And his book is a takeoff in title on Adam Smith, and the title is, “The Wealth and Poverty of Nations.” And the guy’s name is [David] Landes. So I would heartily recommend those 3 books.
