All who met Adam Smith in intimate intercourse are said to have been struck chiefly by the gentleness and benignity of his manner—traits which would naturally strike one in a Scotchman; for men of that unbending race are not often distinguished by easiness of temper or suavity of manner, but are generally both fortiter in re et fortiter in modo. His gentleness was, possibly, only one phase of that timidity which is natural to absent-minded men, and which was always conspicuous in him. That timidity made it rare with him to talk much. When he did talk, as I have said, his hearers marvelled at the ingenuity of his reasoning, at the constructive power of his imagination, at the comprehensiveness of his memory, at the fertility of all his resources; but his inclination was always to remain silent. He was not, however, disinclined to public discourse, and it is chiefly to his unusual gifts as a lecturer that he seems to have owed his advancement in the literary, or, rather, in the university, world.

Acting upon the advice of Lord Kames, an eminent barrister and a man of some standing in the history of philosophy, he volunteered a course of lectures in Edinburgh almost immediately upon his return from Oxford; and the success of this course was hardly assured before he was elected to the chair of Logic in the University of Glasgow. In the following year he had the honor of succeeding to the chair of Moral Philosophy, once occupied by the learned and ingenious Hutcheson. He seems to have been at once successful in raising his new chair to a position of the very highest consideration. His immediate predecessor had been one Thomas Craigie, who has left behind him so shadowy a reputation that it is doubtless safe to conclude that his department was, at his death, much in need of a fresh infusion of life. This it received from Adam Smith. The breadth and variety of the topics upon which he chose to lecture, and the felicity, strength, and vitality of the exposition he gave them (we are told by one who had sat under him), soon drew to Glasgow “a multitude of students from a great distance” to hear him. His mastery of the art of academic lecturing was presently an established fact. It appears clear that his success was due to two things: the broad outlook of his treatment and the fine art of his style. His chair was Moral Philosophy; and ‘moral philosophy’ seems to have been the most inclusive of general terms in the university usage of Scotland at that day, and, indeed, for many years afterward. Apparently it embraced all philosophy that did not directly concern the phenomena of the physical world, and, accordingly, allowed its doctors to give very free play to their tastes in the choice of subjects. Adam Smith, in Glasgow, could draw within the big family of this large-hearted philosophy not only the science of mental phenomena, but also the whole of the history and organization of society; just as, years afterwards, John Wilson, in Edinburgh, could insist upon the adoption of something very like belles-lettres into the same generous and unconventional family circle.

Adam Smith sought to cover the field he had chosen with a fourfold course of lectures. First, he unfolded the principles of natural theology; second, he illustrated the principles of ethics, in a series of lectures which were afterwards embodied in his published work on the “Theory of Moral Sentiments;” third, he discoursed on that branch of morality which relates to the administration of justice; and, last, coming out upon the field with which his name is now identified, he examined those political regulations which are founded, not upon principles of justice, but upon considerations of expediency, and which are calculated to increase the riches, the power, and the prosperity of the State. His notes of his lectures he himself destroyed when he felt death approaching, and we are left to conjecture what the main features of his treatment were, from the recorded recollections of his pupils and from those published works which remain as fragments of the great plan. These fragments consist of the “Theory of Moral Sentiments,” the “Wealth of Nations,” and “Considerations Concerning the First Formation of Languages;” besides which there are, to quote another’s enumeration, “a very curious history of astronomy, left imperfect, and another fragment on the history of ancient physics, which is a kind of sequel to that part of the history of astronomy which relates to ancient astronomy; then a similar essay on the ancient logic and metaphysics; then another on the nature and development of the fine, or, as he calls them, the imitative, arts, painting, poetry, and music, in which was meant to have been included a history of the theatre—all forming part, his executors tell us, ‘of a plan he had once formed for giving a connected history of the liberal and elegant arts;’” part, that is (to continue the quotation from Mr. Bagehot), of the “immense design of showing the origin and development of cultivation and law, or ... of saying how, from being a savage, man rose to be a Scotchman.”

The wideness of view and amazing variety of illustration that characterized his treatment, in developing the several parts of this vast plan, can easily be inferred from an examination of the “Wealth of Nations.”

“The ‘Wealth of Nations,’” declares Mr. Buckle, from whom, for obvious reasons, I prefer to quote, “displays a breadth of treatment which those who cannot sympathize with, are very likely to ridicule. The phenomena, not only of wealth, but also of society in general, classified and arranged under their various forms; the origin of the division of labor, and the consequences which that division has produced; the circumstances which gave rise to the invention of money, and to the subsequent changes in its value; the history of those changes traced in different ages, and the history of the relations which the precious metals bear to each other; an examination of the connection between wages and profits, and of the laws which govern the rise and fall of both; another examination of the way in which these are concerned, on the one hand with the rent of land, and, on the other hand, with the price of commodities; an inquiry into the reason why profits vary in different trades, and at different times; a succinct but comprehensive view of the progress of towns in Europe since the fall of the Roman Empire; the fluctuations, during several centuries, in the prices of the food of the people, and a statement of how it is, that, in different stages of society, the relative cost of meat and of land varies; the history of corporation laws and of municipal enactments, and their bearing on the four great classes of apprentices, manufacturers, merchants, and landlords; an account of the immense power and riches formerly enjoyed by the clergy, and of the manner in which, as society advances, they gradually lose their exclusive privileges; the nature of religious dissent, and the reason why the clergy of the Established Church can never contend with it on terms of equality, and, therefore, call on the State to help them, and wish to persecute when they cannot persuade; why some sects profess more ascetic principles, and others more luxurious ones; how it was, that, during the feudal times, the nobles acquired their power, and how that power has, ever since, been gradually diminishing; how the rights of territorial jurisdiction originated, and how they died away; how the sovereigns of Europe obtained their revenue, what the sources of it are, and what classes are most heavily taxed in order to supply it; the cause of certain virtues, such as hospitality, flourishing in barbarous ages, and decaying in civilized ones; the influence of inventions and discoveries in altering the distribution of power among the various classes of society; a bold and masterly sketch of the peculiar sort of advantages which Europe derived from the discovery of America and of the passage round the Cape; the origin of universities, their degeneracy from the original plan, the corruption which has gradually crept over them, and the reason why they are so unwilling to adopt improvements, and to keep pace with the wants of the age; a comparison between public and private education, and an estimate of their relative advantages; these, and a vast number of other subjects, respecting the structure and development of society, such as the feudal system, slavery, emancipation of serfs, origin of standing armies and of mercenary troops, effects produced by tithes, laws of primogeniture, sumptuary laws, international treaties concerning trade, rise of European banks, national debts, influence of dramatic representations over opinions, colonies, poor-laws—all topics of a miscellaneous character, and many of them diverging from each other—all are fused into one great system, and irradiated by the splendor of one great genius. Into that dense and disorderly mass, did Adam Smith introduce symmetry, method, and law.”

In fact, it is a book of digressions—digressions characterized by more order and method, but by little more compunction, than the wondrous digressions of Tristram Shandy.

It is interesting to note that even this vast miscellany of thought, the “Wealth of Nations,” systematized though it be, was not meant to stand alone as the exposition of a complete system; it was only a supplement to the “Theory of Moral Sentiments;” and the two together constituted only chapters in that vast book of thought which their author would have written. Adam Smith would have grouped all things that concern either the individual or the social life of man under the several greater principles of motive and action observable in human conduct. His method throughout is, therefore, necessarily abstract and deductive. In the “Wealth of Nations,” he ignores the operation of love, of benevolence, of sympathy, and of charity in filling life with kindly influences, and concentrates his attention exclusively upon the operation of self-interest and expediency; because he had reckoned with the altruistic motives in the “Theory of Moral Sentiments,” and he would not confuse his view of the economic life of man by again forcing these in where selfishness was unquestionably the predominant force. “The philosopher,” he held, “is the man of speculation, whose trade is not to do anything, but to observe everything;” and certainly he satisfied his own definition. He does observe everything; and he stores his volumes full with the sagest practical maxims, fit to have fallen from the lips of the shrewdest of those Glasgow merchants in whose society he learned so much that might test the uses of his theories. But it is noticeable that none of the carefully noted facts of experience which play so prominent a part on the stage of his argument speaks of any other principle than the simple and single one which is the pivot of that part of his philosophy with which he is at the moment dealing. In the “Wealth of Nations” every apparent induction leads to self-interest, and to self-interest alone. In Mr. Buckle’s phrase, his facts are subsequent to his argument; they are not used for demonstration, but for illustration. His historical cases, his fine generalizations, everywhere broadening and strengthening his matter, are only instances of the operation of the single abstract principle meant to be set forth.

When he was considering that topic in his course which has not come down to us in any of the remaining fragments of his lectures—the principles of justice, namely—although still always mindful of its relative position in the general scheme of his abstract philosophy of society, his subject led him, we are told, to speak very much in the modern historical spirit. He followed upon this subject, says the pupil already quoted, “the plan which seems to have been suggested by Montesquieu; endeavoring to trace the gradual progress of jurisprudence, both public and private, from the rudest to the most refined ages, and to point out the effects of those arts which contribute to subsistence, and to the accumulation of property, in producing corresponding improvements or alterations in law and government.” In following Montesquieu, he was, of course, following one of the forerunners of that great school of philosophical students of history which has done so much in our own time to clear away the fogs that surround the earliest ages of mankind, and to establish something like the rudiments of a true philosophy of history. And this same spirit was hardly less discernible in those later lectures on the “political institutions relating to commerce, to finances, and to the ecclesiastical and military establishments,” which formed the basis of the “Wealth of Nations.” Everywhere throughout his writings there is a pervasive sense of the realities of fact and circumstance; a luminous, bracing, work-a-day atmosphere. But the conclusions are, first of all, philosophical; only secondarily practical.

It has been necessary to go over this somewhat familiar ground with reference to the philosophical method of Adam Smith, in order to come at the proper point of view from which to consider his place among the old masters of academic lecturing. It has revealed the extent of his outlook. There yet remains something to be said of his literary method, so that we may discern the qualities of that style which, after proving so effectual in imparting power to his spoken discourses, has since, transferred to the printed page, preserved his fame so far beyond the lifetime of those who heard him.

Adam Smith took strong hold upon his hearers, as he still takes strong hold upon his readers, by force, partly, of his native sagacity, but by virtue, principally, of his consummate style. The success of his lectures was not altogether a triumph of natural gifts; it was, in great part, a triumph of sedulously cultivated art. With the true instinct of the orator and teacher, Adam Smith saw—what every one must see who speaks not for the patient ear of the closeted student only, but also to the often shallow ear of the pupil in the class-room, and to the always callous ear of the great world outside, which must be tickled in order to be made attentive—that clearness, force, and beauty of style are absolutely necessary to one who would draw men to his way of thinking; nay, to any one who would induce the great mass of mankind to give so much as passing heed to what he has to say. He knew that wit was of no avail, without wit’s proper words; sagacity mean, without sagacity’s mellow measures of phrase. He bestowed the most painstaking care, therefore, not only upon what he was to say, but also upon the way in which he was to say it. Dugald Stewart speaks of “that flowing and apparently artless style, which he had studiously cultivated, but which, after all his experience in composition, he adjusted, with extreme difficulty, to his own taste.” The results were such as to offset entirely his rugged utterance and his awkward, angular action, and to enable the timid talker to exercise the spells of an orator. The charm of his discourses consisted in the power of statement which gave them life, in the clear and facile processes of proof which gave them speed, and in the vigorous, but chastened, imagination which lent them illumination. He constantly refreshed and rewarded his hearers, as he still constantly refreshes and rewards his readers, by bringing them to those clear streams of practical wisdom and happy illustration which everywhere irrigate his expositions. His counsel, even on the highest themes, was always undarkened. There were no clouds about his thoughts; the least of these could be seen without glasses through the transparent atmosphere of expression which surrounded them. He was a great thinker,—and that was much; but he also made men recognize him as a great thinker, because he was a great master of style—which was more. He did not put his candle under a bushel, but on a candlestick.
