Self-interest, when left uncontrouled, will necessarily lead the proprietors of capitals to prefer that species of employment which is most favourable to national industry, because it is, at the same time, most profitable for themselves--ibid. For, when capitals have been employed in a way different from that suggested by the infallible instinct of self-interest, it has always been in consequence of the peculiar circumstances of the European governments, and of that influence which the vulgar prejudices of merchants have had over the system of administration which these governments have adopted.

The account of these circumstances, with the discussion of the errors of this system, form the matter of the third and fourth books.

Political Economy is, of all sciences, that which affords most room for prejudices, and in which they are most liable to become deeply rooted. The desire of improving our condition, that universal principle, which continually acts upon every member of the community, is ever directing the thoughts of each individual to the means of increasing his private fortune. But should this individual ever chance to raise his views to the management of the public money, he would naturally be led to reason from analogy, and apply to the general interest of his country those principles which reflection and experience have led him to regard as the best guides in the conduct of his own private affairs. Thus, from attending to the fact, that money constitutes a part of the productive stock in the fortune of an individual, and that his fortune increases in proportion to the increase of this article, there arises that erroneous opinion so generally received, that money is a constituent part of national wealth, and that a country becomes rich, in proportion as it receives money from those countries with which it has commercial connections.

Merchants who have been accustomed to retire each night to their desks, to count, with eagerness, the quantity of currency, or of good debts, which their day's sale has produced, calculating their profits only by this result, and confident that such a calculation has never deceived them, are naturally led to think that the affairs of the nation must follow the same rule; and they have been strengthened in this opinion by that unshaken confidence which a long and never-failing experience, that has been the source of wealth and prosperity, inspires. Hence those extravagant opinions respecting the advantages and profits of foreign commerce, and the importance of money; hence those absurd calculations that have been made regarding what is termed the balance of trade, the thermometer of public prosperity; hence those systems of regulations, and those oppressive monopolies, which are resorted to for the purpose of making one side of the balance preponderate; hence, too, those bloody and destructive wars, which have raged in both hemispheres, from the period in which the road to the Indies, and to the new world, became familiar to European nations.

When we observe, that the many bloody wars that have been waged in the different parts of the world for these two last centuries, and even the present war, in many points of view, have had, as their principal end, the maintenance of some monopoly, contrary even to the interest of the nation armed to protect it; we shall feel the full importance of those benefits which the illustrious author of the 'Wealth of Nations' has endeavoured to confer upon mankind, by victoriously combating such strong and baneful prejudices. But we cannot help deeply lamenting, to see how slowly, and with what difficulty, reason in all its strength, and truth in all its clearness, regain the possession of these territories which error and passion have so rapidly overrun.

The prejudices so successfully attacked by Dr. Smith, appear again and again, with undiminished assurance, in the tribunals of legislature, in the councils of administration, in the cabinets of ministry, and in the writings of politicians. They still talk of the importance of foreign and colonial commerce; they still attempt to determine the balance of trade; they renew all the reveries of political arithmetic, as if these questions had not been determined by Smith, in a way which renders them no longer capable of controversy.

It was in the midst of a country, the most deeply imbued with mercantile prejudices; the most completely subjected to its prohibitory policy, that Dr. Smith sapped the foundations of this absurd and tyrannical system; it was at the very moment when England, in alarm, saw, with terror, the possibility of a separation from her American colonies: it was then that he derided the universal fear, and proudly prophesied the success of the colonists, and their approaching independence; and that he confidently announced, what experience has since completely affirmed, the happy consequences which this separation and this independence, so much dreaded, would produce upon the prosperity, both of Great Britain and her colonies-- book 4 , chap. vii.
