Adam Smith was a Scottish economist and philosopher. He has become famous by his influential book The Wealth of Nations (1776). Smith was the son of the comptroller of the customs at Kirkcaldy, Fife, Scotland. The exact date of his birth is unknown. However, he was baptized at Kirkcaldy on June 5, 1723, his father having died some six months previously.
At the age of about fifteen, Smith proceeded to Glasgow University, studying moral philosophy under "the never-to-be-forgotten" Francis Hutcheson (as Smith called him). In 1740 he entered Balliol College, Oxford, but as William Robert Scott has said, "the Oxford of his time gave little if any help towards what was to be his lifework," and he relinquished his exhibition in 1746. In 1748 he began delivering public lectures in Edinburgh under the patronage of Lord Kames. Some of these dealt with rhetoric and belles-lettres, but later he took up the subject of "the progress of opulence," and it was then, in his middle or late 20s, that he first expounded the economic philosophy of "the obvious and simple system of natural liberty" which he was later to proclaim to the world in his Inquiry into the Nature and Causes of the Wealth of Nations. About 1750 he met David Hume, who became one of the closest of his many friends.
In 1751 Smith was appointed professor of logic at Glasgow University, transferring in 1752 to the chair of moral philosophy. His lectures covered the field of ethics, rhetoric, jurisprudence and political economy, or "police and revenue." In 1759 he published his Theory of Moral Sentiments, embodying some of his Glasgow lectures. This work, which established Smith's reputation in his own day, is concerned with the explanation of moral approval and disapproval. His capacity for fluent, persuasive, if rather rhetorical argument is much in evidence. He bases his explanation, not as the third Lord Shaftesbury and Hutcheson had done, on a special "moral sense, nor (like Hume) to any decisive extent on utility, but on sympathy. There has been considerable controversy as how far there is contradiction or contrast between Smith's emphasis in the Moral Sentiments on sympathy as a fundamental human motive, and, on the other hand, the key role of self-interest in the The Wealth of Nations. In the former he seems to put more emphasis on the general harmony of human motives and activities under a beneficent Providence, while in the latter, in spite of the general theme of "the invisible hand" promoting the harmony of interests, Smith finds many more occasions for pointing out cases of conflict and of the narrow selfishness of human motives.
Smith now began to give more attention to jurisprudence and economics in his lecture and less to his theories of morals. An impression can be obtained as to the development of his ideas on political economy from the notes of his lectures taken down by a student in about 1763 which were later edited by E. Cannan (Lectures on Justice, Police, Revenue and Arms, 1896), and from what Scott, its discoverer and publisher, describes as "An Early Draft of Part of The Wealth of Nations", which he dates about 1763.
At the end of 1763 Smith obtained a lucrative post as tutor to the young duke of Buccleuch and resigned his professorship. From 1764-66 he traveled with his pupil, mostly in France, where he came to know such intellectual leaders as Turgot, D'Alembert, André Morellet, Helvétius and, in particular, Francois Quesnay, the head of the Physiocratic school whose work he much respected. On returning home to Kirkcaldy he devoted much of the next ten years to his magnum opus, which appeared in 1776. In 1778 he was appointed to a comfortable post as commissioner of customs in Scotland and went to live with his mother in Edinburgh. He died there on July 17, 1790, after a painfull illness. He had apparently devoted a considerable part of his income to numerous secret acts of charity.
Shortly before his death Smith had nearly all his manuscripts destroyed. In his last years he seems to have been planning two major treatises, one on the theory and history of law and one on the sciences and arts. The posthumously published Essays on Philosophical Subjects (1795) probably contain parts of what would have been the latter treatise.
The Wealth of Nations has become so influential since it did so much to create the subject of economics and develop it into an autonomous systematic discipline. In the western world, it is arguably the most influential book on the subject ever published. When the book, which has become a classic manifesto against mercantalism, appeared in 1776, there was a strong sentiment for free trade in both Britain and America. This new feeling had been born out of the economic hardships and poverty caused by the war. However, at the time of publication, not everybody was convinced of the advantages of free trade right away: the British public and Parliament still clung to mercantilism for many years to come. However, controversial views have been expressed as to the extent of Smith's originality in The Wealth of Nations. Smith has been blamed for relying too much on the ideas of great thinkers such as David Hume and Montesquieu. Nevertheless, The Wealth of Nations was the first widely influential book on the subject of economics, and remains one of the most important books in this field in the present day.
