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 Scotland, in 1778, when he removed to Edinburgh. He was accompanied by his mother, who, though in extreme old age, possessed a considerable share of good health; and his cousin, Miss Douglass, who had long resided with him at Glasgow, undertook to superintend his domestic economy.

The Duke of Buccleugh had continued to allow Mr. Smith L.300 a-year, and the accession which he now received to his income enabled him to live, not only with comfort and independence, but to indulge the benevolence of his heart, in making numerous private benefactions.

During the remaining period of his life, he appears to have done little more than to discharge, with peculiar exactness, the duties of his office, which, though they required no great exertion, were sufficient to divert his attention from his studies. He very early felt the infirmities of old age, but his health and strength were not greatly affected till he was left alone, by the death of his mother, in 1784, and of his cousin four years after. They had been the objects of his affection for more than sixty years; and in their society he had enjoyed, from his infancy, all that he ever knew of the endearments of a family. In return for the anxious and watchful solicitude of his mother during infancy, he had the singular good fortune of being able to show his gratitude to her during a very long life; and it was often observed, that the nearest avenue to his heart was through his mother.

He now gradually declined till the period of his death, which happened in 1790. His last illness, which arose from a chronic obstruction in the bowels, was lingering and painful; but he had every consolation to soothe it which he could desire, from the tenderest sympathy of his friends, and from the completest resignation of his own mind.

His friends had been in use to sup with him every Sunday. The last time he received them, which was a few days before his death, there was a pretty numerous meeting; but not being able to sit up as usual, he retired to bed before supper. On going away, he took leave of the company, by saying, 'I believe we must adjourn this meeting to some other place.'

In a letter addressed, in the year 1787, to the principal of the university of Glasgow, in consequence of his being elected rector of that learned body, a pleasing memorial remains of the satisfaction with which he always recollected that period of his literary career, which had been more peculiarly consecrated to his academical studies. On that occasion he writes: —

'No preferment could have given me so much real satisfaction. No man can owe greater obligations to a society than I do to the university of Glasgow. They educated me; they sent me to Oxford. Soon after my return to Scotland, they elected me one of their own members, and afterwards preferred me to another office, to which the abilities and virtues of the never-to-be-forgotten Dr. Hutcheson had given a superior degree of illustration. The period of thirteen years, which I spent as a member of that society, I remember as by far the most useful, and therefore, as by far the happiest and most honourable period of my life; and now, after three-and-twenty years absence, to be remembered in so very agreeable a manner by my old friends and protectors, gives me a heart-felt joy which I cannot easily express to you.'

Not long before the death of Smith, finding his end approach rapidly, he gave orders to destroy all his manuscripts, excepting some detached essays, which he entrusted to the care of his executors. With the exception of these essays, all his papers were committed to the flames. What were the particular contents of these papers was not known, even to his most intimate friends. The additions to the Theory of Moral Sentiments, most of which were composed under severe illness, had fortunately been sent to the press in the beginning of the preceding winter; and the author lived to see the publication of this new edition.⁴

Some time before his last illness, when he had occasion to go to London, he enjoined his friends, to whom he had entrusted the disposal of his manuscripts, to destroy, in the event of his death, all the volumes of his lectures, doing with the rest what they pleased. When he had become weak, and saw the last period of his life approach, he spoke to his friends again upon the same subject. They entreated him to make his mind easy, as he might depend upon their fulfilling his desire. Though he then seemed to be satisfied, he, some days afterwards, begged that the volume might be immediately destroyed; which was accordingly done.

Mr. Riddell, an intimate friend of Mr. Smith, mentions, that on one of these occasions he regretted he had done so little; 'but I meant,' he added, 'to have done more; and there are materials in my papers of which I could make a great deal. – But that is now out of the question.'

That the idea of destroying such unfinished works as might be in his possession at the time of his death, was not the effect of any sudden or hasty resolution, appears from the following letter to Mr. Hume, written in 1773, at the time when he was preparing for a journey to London, with the prospect of a pretty long absence from Scotland.

'My dear friend, – As I have left the care of all my literary papers to you, I must tell you, that except those which I carry along with me, there are none worth the publication, but a fragment of a great work, which contains a history of the astronomical systems that were successively in fashion down to the time of Descartes. Whether that might not be published as a fragment of an intended juvenile work, I leave entirely to your judgment, though I begin to suspect myself, that there is more refinement than solidity in some parts of it. This little work you will find in a thin folio paper book in my back-room. All the other loose papers which you will find in that desk, or within the glass folding-doors of a bureau, which stands in my bed-room, together with about eighteen thin paper folio books, which you will likewise find within the same glass folding doors, I desire may be destroyed without any examination. Unless I die very suddenly, I shall take care that the papers I carry with me shall he carefully sent to you.'

But he himself long survived his friend Mr. Hume. The persons entrusted with his remaining papers were Dr. Black and Dr. Hutton, his executors, with whom he had long lived in habits of the closest friendship. These gentlemen afterwards collected into a volume, such of the writings of Dr. Smith as were fitted for publication: and they appeared in 1795, under the title of Essays on Philosophical Subjects. These essays had been composed early in life, and were designed to illustrate the principles of the human mind, by a theoretical deduction of the progress of the sciences and the liberal arts. The most considerable piece in this volume is, on the principles which lead and direct philosophical inquiries, illustrated by the history of astronomy, ancient physics, and ancient logic and metaphysics. The others, with the exception of an essay on the external senses, relate to the imitative and liberal arts. The contents of this volume, Mr. Smith's executors observe, appear to be parts of a plan he once had formed for giving a connected history of the liberal sciences and elegant arts; but which he had been obliged to abandon, as being far too extensive; and these parts lay beside him neglected till after his death. In them, however, will be found that happy connection, that full and accurate expression, and the same copiousness and facility of illustration, which are conspicuous in the rest of his writings.

As a writer, the character of Mr. Smith is so well known, that any observation on his merits, must appear almost unnecessary. His literary fame is circumscribed by no ordinary limits. To the voice of his own country, is added the testimony of Europe, and, indeed, of the civilized world. And had even only one volume of his inestimable writings appeared, his name would have been carried down to posterity in the first rank of those illustrious characters that adorn the last century.

In the words of Professor Stewart, it may be said, that, – of the intellectual gifts and attainments by which he was so eminently distinguished; – of the originality and comprehensiveness of his views; the extent, the variety, and the correctness of his information; the inexhaustible fertility of his invention; and the ornaments which his rich and beautiful imagination had borrowed from classical culture; – he has left behind him lasting monuments.

One observation more may he added to what is now said on his writings, that, whatever be the nature of his subject, he seldom misses an opportunity of indulging his curiosity, in tracing, from the principles of human nature, or from the circumstances of society, the origin of the opinions and the institutions which he describes.

With regard to the private character of this amiable and enlightened philosopher, it fortunately happens, that the most certain of all testimonies to his private worth may be found in the confidence, respect, and attachment which followed him through all the various relations of life. There were many peculiarities, indeed, both in his manners and in his intellectual habits; but to those who knew him, these peculiarities, so far from detracting from the respect which his abilities commanded, added an irresistible charm to his conversation, and strongly displayed the artless simplicity of his heart. The comprehensive speculations with which he had always been occupied, and the variety of materials which his own invention continually supplied to his thoughts, rendered him habitually inattentive to familiar objects, and to common occurrences. On this account, he was remarkable, throughout the whole of life, for speaking to himself when alone, and for being so absent in company, as, on some occasions, to exceed almost what the fancy of a Bruyere could imagine. In company, he was apt to be engrossed by his studies; and appeared, at times, by the motion of his lips, as well as by his looks and gestures, to be in the fervour of composition. It was observed, that he rarely started a topic himself, or even fell in easily with the common dialogue of conversation. When he did speak, however, he was somewhat apt to convey his ideas in the form of a lecture; but this never proceeded from a wish to engross the discourse, or to gratify his vanity. His own inclination disposed him so strongly to enjoy, in silence, the gaiety of those around him, that his friends were often led to concert little schemes, in order to bring on the subjects most likely to interest him.
