Very few
authors have done as much as the shy Scotsman Smith (1723-1790) to show
that society does fine when people are free. While Smith didn’t
originate many ideas, his big book The Wealth of Nations (1776) was the
most impressive and influential presentation. He critiqued Britain’s
colonial empire and its system of trade restrictions known as
mercantilism. He explained how society prospers when private individuals
peacefully pursue their self-interest. He affirmed the benefits of
competition. He anticipated public choice economics by telling how
government officials pursue their self-interest expanding their power
and spending more of the taxpayers’ money.
The Wealth of Nations often rises to eloquence. His most famous lines
“As every individual…endeavors as much as he can both to employ his
capital in the support of domestic industry, and so to direct that
industry that its produce may be of the greatest value; every individual
necessarily labours to render the annual revenue of the society as great
as he can. He generally, indeed, neither intends to promote the public
interest, nor knows how much he is promoting it…he intends only his
own gain, and he is in this, as in many other cases, led by an invisible
hand to promote an end which was no part of his intention. Nor is it
always the worse for society that it was no part of it. By pursuing his
own interest he frequently promotes that of the society more effectually
than when he really intends to promote it. I have never known much good
done by those who affected to trade for the public good.” He book
abounds with wonderful lines, like this “In general, if any branch of
trade, or any division of labour, be advantageous to the public, the
freer and more general the competition, it will always be the more so.”
Smith has inspired friends of liberty around the world for more than 200
years.
Smith’s book The Theory of Moral Sentiments (1759) explored human
motivations other than self-interest. He delivered thoughtful lectures
on jurisprudence. He corresponded with the leading thinkers of his day.
Adam Smith offers readers much wisdom and pleasure.
