Recognized almost instantly upon its publication in 1776 as the fundamental work of economics, The Wealth of Nations was also recognized as really long: the original edition totaled over 900 pages in two volumes-including the blockbuster 67-page "digression concerning the variations in the value of silver during the course of the last four centuries," which, according to P. J. O'Rourke, "to those uninterested in the historiography of currency supply, is like reading Modern Maturity in Urdu." Although daunting, Smith's tome is still essential to understanding such current hot topics as outsourcing, trade imbalances, and Angelina Jolie. In this hilarious, approachable, and insightful examination of Smith and his groundbreaking work, O'Rourke puts his trademark wit to good use and shows us why Smith is still relevant, why what seems obvious now was once revolutionary, and why the pursuit of self-interest is so important.
