Adam Smith’s economic views
After two
centuries Adam Smith remains a towering figure in the history of economic
thought.
Unfortunately,
much is known about Smith’s thought than about his life. Though the exact date
of his birth is unknown, he was baptised on June 5, 1723, in Kikcaldy. Of
Smith’s childhood nothing is known other than that he received his elementary
schooling in Kirkcaldy and that at the age of four years he was said to have
been carried off by gypsies. At the age of 14, in 1737, Smith entered the
University of Glasgow, already remarkable as a centre of what was to become
known as the Scottish Enlightenment. There, he was deeply influenced by Francis
Hutcheson, a famous professor of moral philosophy from whose economic and
philosophical views he was later to diverge but whose magnetic character seems
to have been a main shaping force in Smith’s development. The lectures, which
ranged over a wide variety of subjects from rhetoric history and economics,
made a deep impression on some of Smith’s notable contemporaries. They also had
a marked influence on Smith’s own career, for in 1751, at the age of 27, he was
appointed professor of logic at Glasgow, from which post he transferred in 1752
to the more remunerative professorship of moral philosophy.
In 1759 Smith
Published his first work, The Theory of Moral Sentiments. Didactic,
exhortative, and analytic by turns, The Theory lays the psychological
foundation on which The Wealth of Nations was later to be built. In it Smith
described the principles of “human nature “, which, together with Hume and the
other leading philosophers of his time, he took as a universal and unchanging
datum from which social institutions, as well as social behaviour, could be
deduced.
One question in
particular interested Smith in The Theory of Moral Sentiments. This was a
problem that had attracted Smith’s teacher Hutcheson and a number of Scottish
philosophers before him. The question was the source of the ability to form
moral judgements, including judgements on one’s own behaviour, in the face of
the seemingly overriding passions for self-preservation and self-interest.
Smith’s answer, at considerable length, is the presence within each of us of an
“inner man” who plays the role of the “impartial spectator”, approving or condemning
our own and others’ actions with a voice impossible to disregard. (The theory
may sound less naive if the question is reformulated to ask how instinctual
drives are socialized through the superego).
The Theory
quickly brought Smith wide esteem and in particular attracted the attention of
Charles Townshend, himself something of an amateur economist, a considerable
wit, and somewhat less of a statesman, whose fate it was to be the chancellor
of the exchequer responsible for the measures of taxation that ultimately
provoked the American Revolution. Townshend had recently married and was
searching for a tutor for his stepson and ward, the young Duke of Buccleuch.
The terms of
employment were lucrative (an annual salary of £300
plus travelling expenses and a pension of £300 a year after),
considerably more than Smith had earned as a professor. Accordingly, Smith
resigned his Glasgow post in 1763 and set off for France the next year as the
tutor of the young duke. Late that year he returned to Kirkcaldy, where the
next six years were spent dictating and reworking The Wealth of Nations,
followed by another stay of three years in London, where the work was finally
completed and published in 1776.
Despite its
renown as the first great work in political economy, The Wealth of Nations is
in fact a continuation of the philosophical theme begun in The Theory of Moral
Sentiments. The ultimate problem to which Smith addresses himself is how the
inner struggle between the passions and the “impartial spectator’ - explicated
in Moral Sentiments in terms of the single individual - works its effects in
the larger arena of history itself, both in the long-run evolution of society
and in terms of the immediate characteristics of the stage of history typical
of Smith’s own day.
The answer to
this problem enters in Book 5, in which Smith outlines he four main stages of
organization through which society is impelled, unless blocked by deficiencies
of resources, wars, or bad policies of government: the original “rude’ state of
hunters, a second stage of nomadic agriculture, a third stage of feudal or
manorial “farming”, and a fourth and final stage of commercial interdependence.
It should be
noted that each of these stages is accompanied by institutions suited to its
needs. For example, in the age of the huntsman, “there is scar any established
magistrate or any regular administration of justice. “ With the advent of flocks there emerges a
more complex form of social organization, comprising not only “formidable”
armies but the central institution of private property with its indispensable
buttress of law and order as well. It is the very essence of Smith’s thought
that he recognized this institution, whose social usefulness he never doubted,
as an instrument for the protection of privilege, rather than one to be
justified in terms of natural law: “Civil government,” he wrote, “so far as it
is instituted for the security of property, is in reality instituted for the
defence of the rich against the poor, or of those who have some property
against those who have none at all.” Finally, Smith describes the evolution
through feudalism into a stage of society requiring new institutions such as
market-determined rather than guild-determined wages and free rather than
government-constrained enterprise. This later became known as laissez-faire
capitalism; Smith called it the system of perfect liberty.
The theory of
historical evolution, although it is perhaps the binding conception of The
Wealth of Nations, is subordinated within the work itself to a detailed
description of how the “invisible hand” actually operates within the
commercial, or final, stage of society. This becomes the focus of Books I and
II. In which Smith undertakes to elucidate two questions. The first is how a
system of perfect liberty, operating under the drives and constraints of human
nature and intelligently designed institutions, will give rise to an orderly
society. The question, which had already been considerably elucidated by
earlier writers, required both an explanation of the underlying orderliness in
the pricing of individual commodities and an explanation of the “laws” that
regulated the division of the entire “wealth” of the nation (which Smith saw as
its annual production of goods and services) among the three great claimant
classes - labourers, landlords, and manufacturers.
It is in the
unintended outcome of this competitive struggle for self-betterment that the
invisible hand regulating the economy shows itself, for Smith explains how
mutual vying forces the prices of commodities down to their natural levels,
which correspond to their costs of production. Moreover, by inducing labour and
capital to move from less to more profitable occupations or areas, the
competitive mechanism constantly restores prices to these “natural” levels
despite short-run aberrations.
Smith’s analysis
of the market as a self- correcting mechanism was impressive. But his purpose
was more ambitious than to demonstrate the self-adjusting properties of the
system. Rather, it was to show that, under the impetus of the acquisitive
drive, the annual flow of national wealth could be seen steadily to grow.
Thus, the wealth
of nations would grow only if individuals, through their governments, did not
inhibit this growth by catering to the pleas for special privilege that would
prevent the competitive system from exerting it’s begin effect. Consequently,
much of The Wealth of Nations, especially Book IV, is a polemic against the
restrictive measures of the “mercantile system” that favored monopolies at home
and abroad. Smith’s system of “natural liberty”, he is careful to point out,
accords with the best interests of all but will not be put into practice if
government is entrusted to, or heeds, the “mean rapacity, which neither is, nor
ought to be, the rulers of mankind.”
