in the history of each of these eminent ' men, from the ambition which both have shown to record it to posterity. In 1751, he was elected Professor of Logic in the University of Glasgow; and, the year following, he was removed to the Professorship of Moral Philosophy in the same University, upon the death of Mr. Thomas Craigie, the immediate successor of Dr. Hutcheson. In this situation, he remained thirteen years; a period he used frequently to look back to, as the most useful and happy of his life. It was indeed a situation in which he was eminently fitted to excel, and in which the daily labors of his profession were constantly recalling his attention to his favorite pursuits, and familiarizing his mind to those important speculations he was afterwards to communicate to the world. In this view, though it afforded, in the mean time, but a very narrow scene, for his ambition, it was probably instrumental, in no inconsiderable degree, to the future eminence of his literary character. Of Mr. Smith's lectures while a Professor at Glasgow, no part has been preserved, excepting what he himself published in the Theory of Moral Sentiments and in the Wealth of Nations. The Society therefore, I am persuaded, will listen with pleasure to the following short account of them, for which I am indebted to a gentleman who was formerly one of Mr. Smith's pupils, and who continued till his death to be one of his most intimate and valued friends. “In the Professorship of Logic, to which Mr. Smith was appointed on his first introduction into this University, he soon saw the necessity of departing widely from the plan that had been followed by his predecessors, and of directing the attention of his pupils to studies of a more interesting and useful nature than the logic and metaphysics of the schools. Accordingly, after exhibiting a general view of the powers of the mind, and explaining so much of the ancient logic as was requisite to gratify curiosity with respect to an artificial method of reasoning, which had once occupied the universal attention of the learned, he dedicated all the rest of his time to the delivery of a system of rhetoric and belles lettres. The best method of explaining and illustrating the various powers of the human mind, the most useful part of metaphysics, arises from an examination of the several ways of communicating our thoughts by speech, and from an attention to the principles of those literary compositions which contribute to persuasion or entertainment. By these arts, every thing that we perceive or feel, every operation of our minds, is expressed and delineated in such a manner, that it may be clearly distinguished and remembered. There is, at the same time, no branch of literature more suited to youth at their first entrance upon philosophy than this, which lays hold of their taste and their feelings. “It is much to be regretted, that the manuscript containing Mr. Smith's lectures on this subject was destroyed before his death. The first part, in point of composition, was highly finished; and the whole discovered strong marks of taste and original genius. From the permission given to students of taking notes, many observations and opinions contained in these lectures have either been detailed in separate dissertations, or engrossed in general collections, which have since been given to the public. But these, as might be expected, have , lost the air of originality and the distinctive character which they received from their first author, and are often obscured by that multiplicity of common-place matter in which they are sunk and involved. “About a year after his appointment to the Professorship of Logic, Mr. Smith was elected to the chair of Moral Philosophy. His course of lectures on this subject was divided into four parts. The first contained Natural Theology; in which he considered the proofs of the being and attributes of God, and those principles of the human mind upon which religion is founded. The second comprehended Ethics strictly so called, and consisted chiefly of the doctrines which he afterwards published in his Theory of Moral Sentiments. In the third part, he treated at more length of that branch of morality which relates to justice, and which, being sus rope. In the former of these papers, he points out some defects in Dr. Johnson's plan, which he censures as not sufficiently grammatical. “The different significations of a word,” he observes,“ are indeed collected; but they are seldom digested into general classes, or ranged under the meaning which the word principally expresses: And sufficient care is not taken to distinguish the words apparently synonymous.” To illustrate this criticism, he copies from Dr. Johnson the articles but and humour, and opposes to them the same articles digested agreeably to his own idea. The various significations of the word but are very nicely and happily discriminated. The other article does not seem to have been executed with equal care. The observations on the state of learning in Europe are written with ingenuity and elegance; but are chiefly interesting, as they show the attention which the author had given to the philosophy and literature of the Continent, at a period when they were not much studied in this island. In the same volume with the Theory of Moral Sentiments, Mr. Smith published a Dissertation on the Origin of Languages, and on the different Genius of those which are original and compounded.” The remarks I have to offer on these two discourses, I shall, for the sake of distinctness, make the subject of a separate section. SECTION II. Of the Theory of Moral Sentiments, and the Dissertation on the Origin of Languages. The science of Ethics has been divided by modern writers into two parts; the one comprehending the theory of Morals, and the other its practical doctrines. The questions about which the former is employed, are chiefly the two following: 1. By what principle of our constitution are we led to form the notion of moral distinctions ;-whether by that faculty which perceives the distinction between truth and falsehood; or by a peculiar power of perception, which is pleased with one set of qualities, and displeased with another? 2. What is the proper object of moral approbation; or, in other words, What is the common quality or qualities belonging to all the different modes of virtue? Is it benevolence; or a rational self-love; or a disposition to act suitably to the different relations in which we are placed? These two questions seem to exhaust the whole theory of Morals. The scope of the one is to ascertain the origin of our moral ideas; that of the other, to refer the phenomena of moral perception to their most simple and general laws. The practical doctrines of morality comprehend all those rules of conduct which profess to point out the proper ends of human pursuit, and the most effectual means of attaining them; to which we may add all those literary compositions, whatever be their particular form, which have for their aim to fortify and animate our good dispositions, by delineations of the beauty, of the dignity, or of the utility of Virtue. I shall not inquire at present into the justness of this division. I shall only observe, that the words theory and practice are not, in this instance, employed in their usual acceptations. The theory of Morals does not bear, for example, the same relation to the practice of Morals, that the theory of geometry bears to practical geometry. In this last science, all the practical rules are founded on theoretical principles previously established: But in the former science, the practical rules are obvious to the capacities of all mankind; the theoretical principles form one of the most difficult subjects of discussion that have ever exercised the ingenuity of metaphysicians. In illustrating the doctrines of practical morality, (if we make allowance for some unfortunate prejudices produced or encouraged by violent and oppressive systems of policy,) the ancients seem to have availed themselves of every light furnished by nature to human reason; and indeed those writers who, in later times, have treated the subject with the greatest success, are they who have followed most closely the footsteps of the Greek and the Roman philosophers. The theoreti. cal question, too, concerning the essence of virtue, or the proper object of moral approbation, was a favorite topic of discussion in the ancient schools. The question concerning the principle of moral approbation, though not entirely of modern origin, has been chiefly agitated since the writings of Dr. Cudworth, in opposition to those of Mr. Hobbes; and it is this question accordingly, (recommended at once by its novelty and difficulty to the curiosity of speculative men,) that has produced most of the theories which characterize and distinguish from each other the later systems of moral philosophy, It was the opinion of Dr. Cudworth, and also of Dr. Clarke, that moral distinctions are perceived by that power of the mind which distinguishes truth from falsehood. This system it was one great object of Dr. Hutcheson's philosophy to refute, and in opposition to it, to show that the words right and wrong express certain agreeable and disagreeable qualities in actions, which it is not the province of reason but of feeling to perceive; and to that power of perception which renders us susceptible of pleasure or of pain from the view of virtue or of vice, he gave the name of the Moral Sense. His reasonings upon this subject are in the main acquiesced in, both by Mr. Hume and Mr. Smith; but they differ from him in one important particular,— Dr. Hutcheson plainly supposing, that the moral sense is a simple principle of our constitution, of which no account can be given ; whereas the other two philosophers have both attempted to analyze it into other principles more general. Their systems, however, with respect to it are very different from each other. According to Mr. Hume, all the qualities which are denominated virtuous, are useful either to ourselves or to others, and the pleasure which we derive from a view of them is the pleasure of utility. Mr. Smith, without rejecting entirely Mr. Hume's doctrine, proposes another of his own, far more comprehensive; a doctrine with which he thinks all the most celebrated theo |
