" An Inquiry into the Nature and Causes of the Wealth of Nations, which Smith published in 1776, is the most important book ever written about capitalism and its moral ramifications. Though The Wealth of Nations is in good part about commerce, it was not written for businessmen or merchants. A book focused on the analysis of market processes motivated by self-interest, it was written by one of the most admired philosophers of the Enlightenment, a former professor of logic, rhetoric, jurisprudence, and moral philosophy, in order to influence politicians and rouse them to pursue the common good.
