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.
