Dr. Mandeville has also, of late, got the credit of being the author of those Principles of Political Economy, which have interested the world for the last fifty years, and to him alone, it is said, not only the English, but also the French writers, are indebted for their doctrines in that science. In the work of this eccentric writer, there seems, indeed, a similarity of opinion on some of the more obvious sources of wealth, particularly in the division of labour, which Dr. Smith investigates so fully; and in the erroneous doctrine of productive and non-productive labour; and also, perhaps, on some other points: but it would be difficult to show, that he ought, on this account, to be considered the author of all, or even the chief part of what has been written on the subject. On this, as well as on all questions of a similar nature, a great diversity of opinions will subsist. But it may be a matter of curiosity to those who are unacquainted with his work, the Fable of the Bees, not only to trace the connection of that author's sentiments with what is advanced by subsequent writers on this important subject, but also to learn his peculiar notions of morality, that attracted, at one time, so much attention. These last, Dr. Smith says, though described by a lively and humorous, yet coarse and rustic eloquence, which throws an air of truth and probability on them, are, almost in every respect, erroneous.
Soon after the publication of the Wealth of Nations, Mr. Smith received the following congratulatory letter from Mr. Hume, six months before his death, dated Edinburgh, 1st April 1776.
'Euge! Belle! Dear Mr. Smith – I am much pleased with your performance, and the perusal of it has taken me from a state of great anxiety. It was a work of so much expectation, by yourself, by your friends, and by the public, that I trembled for its appearance; but am now much relieved; not but that the reading of it necessarily requires so much attention, and the public is disposed to give so little, that I shall still doubt for some time of its being at first very popular. But it has depth, and solidity, and acuteness, and is so much illustrated by curious facts, that it must at last take the public attention. It is probably much improved by your last abode in London. If you were here at my fireside, I should dispute some of your principles. But these, and a hundred other points, are fit, only to be discussed in conversation. I hope it will be soon, for I am in a very bad state of health, and cannot afford a long delay.'
The publication of this great work drew praise to its author, indeed, from many different quarters. – Dr. Barnard, in a political epistle, addressed to Sir Joshua Reynolds, where the characteristic qualities of some eminent literary men of that time are brought forward, spoke of Smith as one who would teach him how to think. Gibbon made honourable mention of him in his Roman history; and Mr. Fox contributed, in no small degree, to extend his reputation, by observing in the House of Commons, that 'the way, as my learned friend Dr. Adam Smith says, for a nation, as well as an individual, to be rich, is for both to live within their income.'
The opinion which Dr. Johnson delivered, at that time, on its being alleged by Sir John Pringle, that a person who, like Dr. Smith, was not practically acquainted with trade, could not be qualified to write on that subject, may also be mentioned here, though somewhat erroneous, as far as it respects the received doctrines of Political Economy: – 'He is mistaken,' said Johnson. 'A man who has never been engaged in trade himself, may undoubtedly write well on trade; and there is nothing which requires more to be illustrated by philosophy than trade does. As to mere wealth, that is to say, money, it is clear that one nation, or one individual, cannot increase its store but by making another poorer; but trade procures what is more valuable, the reciprocation of the peculiar advantages of different countries. A merchant seldom thinks of any but his own trade. To write a good book upon it, a man must have extensive views. It is not necessary to have practised, to write well upon a subject.'2
On the Inquiry into the Causes of the Wealth of Nations, it only remains farther to be observed, that its success has been every way commensurate to its merits. It has, however, been often regretted, that the author did not live to favour the world with his reasonings on those important events which have taken place since 1784, when he put the last hand to his invaluable work. That another, with competent talents, and a mind disposed to the task, should soon appear, to treat of these occurrences, and give a satisfactory view of the progress of the science from that time to the present, is not to be expected. But as the honour to be gained from a successful execution of such an undertaking is very considerable, it is not to be wondered at that an attempt of this kind should be made. Accordingly, Mr Playfair of London has had the boldness to follow Smith, by endeavouring to supply, in part, this desideratum, by adding supplementary chapters and notes to the Treatise on the Wealth of Nations.
But it is greatly to be feared, that there are few persons who have read this improved edition, as it is called, of Dr. Smith's Inquiry, but will still look forward to the accomplishment of the wishes they must previously have formed, for a continuation, and probably an illustration, of the discussions contained in that work. Leaving, therefore, the supplementary chapters and elucidations of Mr Playfair, it must be observed, that Dr. Smith has, on this occasion, been equally unfortunate in a biographer. The detail of his peaceful life is almost lost among dissertations on the wickedness of atheism and the horrors of a revolution. But these dissertations, strangely misplaced as they appear to be, would certainly not alone have been sufficient to attract observation here, whatever latitude the author might have allowed to himself on such subjects. When he goes on, however, to apologise for Dr. Smith's acquaintance with some individuals among the economists, and to connect the whole of that sect with those philosophers to whom he ascribes the evils which have so long afflicted France, his opinions become still more insupportable. It will, perhaps, be said, and with some reason, that, in this instance, at least, the writer has followed those alarmists, who, on any men of learning belonging to that country being mentioned, immediately ally them to the revolutionists without regard to difference of opinion, or distance of time.
The reputation, however, of the economists is too well established to be affected, either by the clamours of the ignorant, or the mad intemperance of political alarmists. The doctrine of the great men who formed the school of the economists, was, that the produce of the land is the sole or principal source of the revenue and wealth of every country; and this doctrine, with the manner of deriving from it the greatest possible advantage, it is almost universally acknowledged, engaged entirely their attention. Dr. Smith, who lived in great intimacy with many of the founders of that sect, does ample justice, on every occasion, to the purity of their views; and indeed they, as well as himself, it has always been said, by the impartial and well informed, were ever animated by a zeal for the best interests of society.
M. Quesnai, the first of that sect, and the author of the Economical Table, a work of the greatest profoundness and originality, was, in particular, represented by Mr. Smith as a man of the greatest modesty and simplicity; and his system he pronounced, with all its imperfections, to be the nearest approximation to the truth, of any that had then been published on the principles of political science. His veneration for this worthy man was even so great, that had he lived, it was his intention to have inscribed to him the Inquiry into the Causes of the Wealth of Nations.
Nor will the memory of those illustrious men be soon forgotten, notwithstanding the calumnies with which it has been charged. It may safely be predicted, in the words of a highly respectable periodical publication, that 'Those prospects of political improvements which flattered the benevolent anticipations of the economists, will soon be recognised as sound conclusions of science; and it will at length be acknowledged that Turgot, Mirabeau, and Quesnai, were the friends of mankind, and that their genius and their labours were devoted to the refinement of social happiness and the consolidation of the political fabric.'3
The life of Mr. Smith, after the publication of his Inquiry, might be said to draw towards a close. The following particulars of the last years, are mostly extracted from Professor Stewart's Life of this incomparable writer.
After residing some time in London, he was appointed one of the commissioners of customs in
