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.'
During the following year, he was nominated professor of moral philosophy in the same university. By this appointment he was peculiarly gratified, and the duties of it he was well fitted to discharge, as it embraced the study of his favourite science, political economy, many of the doctrines of which, even then, had been familiarised to his mind. After entering on the duties of his new situation, he appears to have turned his attention to the division of the science of morals, which he was induced to divide 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. In the third, he treated, at more length, of that branch of morality which relates to Justice, and which, being susceptible of precise and accurate rules, is capable of a more systematic demonstration. In the fourth, he examined these political regulations which are founded upon Expediency, and which are calculated to increase the riches, the power, and the prosperity of a state.
His lectures on these subjects were always distinguished by a luminous division of the subject, and by fulness and variety of illustration; and as they were delivered in a plain unaffected manner, they were well calculated to afford pleasure as well as instruction. They, accordingly, excited a degree of interest, and gave rise to a spirit of inquiry in the great commercial city of Glasgow, from which the most favourable consequences resulted. His reputation extended so widely, that, on his account alone, a considerable number of students, from different parts of the country, were attracted to the university of that city; and the science which he taught became so popular, that even the trifling peculiarities in his pronunciation and manner of speaking, were often objects of imitation.
During the time Mr. Smith was thus successfully engaged in his academical labours, he was gradually laying the foundation of a more extensive reputation. In the year 1759, he published his 'Theory of Moral Sentiments, or An Essay towards an Analysis of the Principles by which Men naturally judge concerning the Conduct and Character, first of their Neighbours, and afterwards of Themselves.' This work was founded on the second division of his lectures, and was divided into six parts:--The propriety of action: Merit and demerit, or the objects of reward and punishment: The foundation of our judgments concerning our own sentiments and conduct, and of the sense of duty: The effect of utility upon the sentiment of approbation: The influence of custom and fashion upon the sentiments of moral approbation and disapprobation: And, lastly, The character of virtue. To these were added, a brief view of the different systems of ancient and modern philosophy, which is universally acknowledged to be the most candid and luminous that has yet appeared.
This Essay soon attracted a great share of the public attention, by the ingenuity of the reasonings, and the perspicuity with which they were displayed. The principle on which it is founded may be said to be, That the primary objects of our moral perceptions are the actions of other men; and that our moral judgments, with respect to our own conduct, are only applications to ourselves of decisions which we have already passed on the conduct of others. With this doctrine the author thinks all the most celebrated theories of morality coincide in part, and from some partial view of it he apprehends they are all derived. To the same work was subjoined a short treatise on the first formation of language, and considerations on the different genius of those which were original and compounded.
