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.”
