This inability to recollect in a completely waking state what had taken place during the morbid one separates this story from all the rest that are told of Smith's absence of mind. For his friends used always to observe of his fits of abstraction what a remarkable faculty he possessed of recovering, when he came to himself, long portions of the conversation that had been going on around him while his mind was absent. But here there is an entire break between the one state and the other; the case seems more allied to trance, though it doubtless had the same origin as the more ordinary fits of absence, and, like them, was only one of the penalties of that power of profound and prolonged concentration to which the world owes so much; it was thinker's cramp, if I may use the expression. In one way Smith took more interest in his official work than ordinary Commissioners would do, because he found it useful to his economic studies. In 1778 he wrote Sir John Sinclair, who had desired a loan of the French inquiry entitled Mémoires concernant les Impositions, that "he had frequent occasion to consult the book himself both in the course of his private studies and in the business of his present employment," and Sir John states that Smith used to admit "that he derived great advantage from the practical information he derived by means of his official situation, and that he would not have otherwise known or believed how essential practical knowledge was to the thorough understanding of political subjects."[288] This is confirmed by the fact that most of the additions and corrections introduced into the third edition of the Wealth of Nations—the first published after his settlement in the Customs—are connected with that branch of the public service.
Still his friends were perhaps right in lamenting that the duties of this office, light though they really were, used up his time and energy too completely to permit his application to the great work on government which he had projected. "Though they required little exertion of thought, they were yet," says Dugald Stewart, "sufficient to waste his spirits and dissipate his attention; and now that his career is closed, it is impossible to reflect on the time they consumed without lamenting that it had not been employed in labours more profitable to the world and more equal to his mind. During the first years of his residence in this city his studies seemed to be entirely suspended, and his passion for letters served only to amuse his leisure and to animate his conversation. The infirmities of age, of which he very early began to feel the approach, reminded him at last, when it was too late, of what he yet owed to the public and to his own fame. The principal materials of the works which he had announced had been long ago collected, and little probably was wanting but a few years of health and retirement to bestow on them that systematical arrangement in which he delighted."[289]
His leisure seems to have been passed during these later years of his life very largely in the study of the Greek poets, and he frequently remarked to Dugald Stewart, when found in his library with Sophocles or Euripides open before him on the table, that of all the amusements of old age, the most grateful and soothing was the renewal of acquaintance with the favourite studies and the favourite authors of our youth.[290] Besides, the work of composition seems to have grown really more arduous to him. He was always a slow composer, and had never acquired increased facility from increased practice. Much of his time too was now given to the enjoyments of friendship. I have already mentioned his Sunday suppers, but besides these he founded, soon after settling in Edinburgh, in co-operation with the two friends who were his closest associates during the whole of this last period of his career—Black the chemist, and Hutton the geologist—a weekly dining club, which met every Friday at two o'clock in a tavern in the Grassmarket. Dr. Swediaur, the Paris physician, who spent some time in Edinburgh in 1784 making researches along with Cullen, and was made a member of this club during his stay, writes Jeremy Bentham: "We have a club here which consists of nothing but philosophers. Dr. Adam Smith, Cullen, Black, Mr. M'Gowan, etc., belong to it, and I am also a member of it. Thus I spend once a week in a most enlightened and agreeable, cheerful and social company." And of Smith, with whom he says he is intimately acquainted, he tells Bentham he "is quite our man"—in opinion and tendencies, I presume. Ferguson was a member of the club, though after being struck with paralysis in 1780 he never dined out; but among the constant attenders were Henry Mackenzie, Dugald Stewart, Professor John Playfair, Sir James Hall the geologist; Robert Adam, architect; Adam's brother-in-law, John Clerk of Eldin, inventor of the new system of naval tactics; and Lord Daer—the "noble youthful Daer"—who was the first lord Burns ever met, and taught the poet that in a lord he after all but "met a brither," with nothing uncommon about him,
Except good sense and social glee,
An' (what surprised me) modesty.
Lord Daer was the eldest son of the fourth Earl of Selkirk, and, on the outbreak of the French Revolution, a few years after Burns met him, became one of the most ardent of the "Friends of the People"; and was intimate with Mirabeau, to whom he ventured to speak a word for the king's safety, and was told that the French would not commit the English blunder of cutting off their king's head, because that was the usual way to establish a despotism.[291] Great expectations were cherished of Lord Daer's future, but they were defeated by his premature death in 1794. The Mr. M'Gowan mentioned by Swediaur is little known now, but he was an antiquary and naturalist, a friend and correspondent of Shenstone, Pennant, and Bishop Percy. M'Gowan kept house with a friend of his youth, who had returned to him after long political exile, Andrew Lumisden, Prince Charlie's Secretary, who was also a warm friend of Smith, and whose portrait by Tassie is one of the few relics of Smith's household effects which still exist. Lumisden had been Hamilton of Bangour's companion in exile at Rouen, and was no doubt also a member of this club.
According to Playfair, the chief delight of the club was to listen to the conversation of its three founders. "As all the three possessed great talents, enlarged views, and extensive information, without any of the stateliness and formality which men of letters think it sometimes necessary to affect, as they were all three easily amused, and as the sincerity of their friendship had never been darkened by the least shade of envy, it would be hard to find an example where everything favourable to good society was more perfectly united, and everything adverse more entirely excluded."[292] This friendship of Smith, Black, and Hutton, if not so famous as the friendship between Smith and Hume, was not less really memorable. Each of them had founded—or done more than any other single person to found—a science; they may be called the fathers of modern chemistry, of modern geology, and of modern political economy; and for all their great achievements, they were yet men of the most unaffected simplicity of character. In other respects they were very different from one another, but their differences only knit them closer together, and made them more interesting to their friends.
Black was a man of fine presence and courtly bearing, grave, calm, polished, well dressed, speaking, what was then rare, correct English without a trace of Scotch accent, and always with sense and insight even in fields beyond his own. Smith used to say that he never knew a man with less nonsense in him than Dr. Black, and that he was often indebted to his better discrimination in the judgment of character, a point in which Smith, not only by the general testimony of his acquaintance, but by his own confession, was by no means strong, inasmuch as he was, as he acknowledges, too apt to form his opinion from a single feature. Now the judgment of character was, according to Robison, Black's very strongest point. "Indeed," says Robison, "were I to say what natural talent Dr. Black possessed in the most uncommon degree, I should say it was his judgment of human character, and a talent which he had of expressing his opinion in a single short phrase, which fixed it in the mind never to be forgotten."[293] He was a very brilliant lecturer, for Brougham, who had been one of his students, said that he had heard Pitt and Fox and Plunket, but for mere intellectual gratification he should prefer sitting again on the old benches of the chemistry classroom, "while the first philosopher of his age was the historian of his own discoveries"; and, adored as he was by his students, he was the object of scarce less veneration and pride to the whole body of his fellow-citizens. Lord Cockburn tells us how even the wildest boys used to respect Black. "No lad," says he, "could ever be irreverent towards a man so pale, so gentle, so elegant, and so illustrious."
Hutton was in many respects the reverse of Black. He was a dweller out of doors, a man of strong vitality and high spirits, careless of dress and appearance, setting little store by the world's prejudices or fashions, and speaking the broadest Scotch, but overflowing with views and speculations and fun, and with a certain originality of expression, often very piquant. Every face brightened, says Playfair, when Hutton entered a room. He had been bred a doctor, though he never practised, but, devoting himself to agriculture, had been for years one of the leading improvers of the Border counties, and is said, indeed, to have been the first man in Scotland to plough with a pair of horses and no driver, the old eight-ox plough being then in universal use. Between his early chemical studies and his later agricultural pursuits, his curiosity was deeply aroused as he walked about the fields and dales, not merely concerning the composition but the origin of the soils and rocks and minerals that lay in the crust of the globe, and he never ceased examining and speculating till he completed his theory of the earth which became a new starting-point for all subsequent geological research. He was a bold investigator, and Playfair distinguishes him finely in this respect from Black by remarking that "Dr. Black hated nothing so much as error, and Dr. Hutton nothing so much as ignorance. The one was always afraid of going beyond the truth, and the other of not reaching it." He went little into general society, but Playfair says that in the more private circles which he preferred he was the most delightful of companions.
The conversation of the club was often, as was to be expected from its composition, scientific, but Professor Playfair says it was always free, and never didactic or disputatious, and that "as the club was much the resort of the strangers who visited Edinburgh from any objects connected with art or with science, it derived from them an extraordinary degree of vivacity and interest."[294]
Its name was the Oyster Club, and it may be thought from that circumstance that those great philosophers did not spurn the delights of more ordinary mortals. But probably no three men could be found who cared less for the pleasures of the table. Hutton was an abstainer; Black a vegetarian, his usual fare being "some bread, a few prunes, and a measured quantity of milk diluted with water"; and as for Smith, his only weakness seems to have been for lump sugar, according to an anecdote preserved by Scott, which, trivial though it be, may be repeated here, under the shelter of the great novelist's example and of Smith's own biographical principle that nothing about a great man is too minute not to be worth knowing.
