The Wealth of Nations, one of the earliest attempts to study the rise of industry and commercial development in Europe, was a precursor to the modern academic discipline of economics. It provided one of the best-known intellectual rationales for free trade and
capitalism, greatly influencing the writings of later economists. During and after the bicentennial celebration of the Wealth of Nations in 1976, much more attention has been paid to The Theory of Moral Sentiments as well as to his use of rhetoric, his views on virtue, government intervention or on the provision of public health, public works and education and his opposition to slavery, morally and economically, inequality, including racial inequality, and to beliefs in the color line, the inferiority of blacks, and the poor and the Irish. Nor did Smith believe that common sense was inferior to science.. Topics that increased in frequency after 1976 include: calling him a moral philosopher and scientist or economist, pointing to a need to read both of his two major works, and his lesser works as well, describing his "economic man" as also a moral man, presenting his interests in virtue and morality, identifying the effects of his definition of the separation of the church and state, and of various of forms of government, including republics, on ending or promoting slavery, war, or both, characterizing mercantilism, slavery and colonialism, monopoly, as less efficient, and more expensive than free trade, free labor, or labor not coerced by want, misery, or force, discussing his legacy as a "lost legacy", citing his enemies and those who are and have "purloined" or "coopted" his works, looking at the British's government response to him and other English citizens who were his friends after the French Revolution, and his response to religion and querying why he did not publish promised works.
Overall, a heightened interest in Adam Smith and his works has been sustained until today. Among those reporting on such trends as more than a "speculative bubble" is economist Jonathan B. Wight in a 2004 conference paper titled "Is There a Speculative Bubble in Scholarship on Adam Smith?", presented at the Eleventh World Congress of Social Economics, Albertville, France. Wight, in addition to being the author of this paper and of other books and articles on Adam Smith and his works, also reports in 2002 that six hundred articles and thirty books had been published in the twenty seven years between 1970 and 1997. Only two articles on Adam Smith or his works were published the year before 1971 Wight also reports in a journal article, "The Rise of Adam Smith: Articles and Citations, 1970-1997".
There, in addition, has been a controversy over the extent of Smith's originality in
The Wealth of Nations. Some argue that the work added only modestly to the already established ideas of thinkers such as
Anders Chydenius (
The National Gain 1765),
David Hume and the
Baron de Montesquieu. Indeed, many of the theories Smith set out simply described historical trends away from mercantilism and towards free trade that had been developing for many decades and had already had significant influence on governmental policy. Nevertheless, Smith's work organized their ideas comprehensively, and so remains one of the most influential and important books in the field today.
Smith was ranked #30 in Michael H. Hart's
list of the most influential figures in history.
From 13 March 2007 onwards Smith's portrait appeared in the UK on new
£20 notes. He is the first Scotsman to feature on a currency issued by the
Bank of England. A picture of the note is available on the Bank of England website.
On
June 25 2006, when
Warren Buffet announced that he would donate his wealth to
The Bill and Melinda Gates Foundation, he was presented with a copy of Adam Smith's
Wealth of Nations by
Bill Gates.
