Hume may be found indirectly lamenting the fate of his own work on metaphysics, in his remarks on other works of a kindred character; and in these criticisms we have a clue to the expectations he had formed. In his well-known rapid criticism on the literature of the epoch of the civil wars, he says of Hobbes: "No author in that age was more celebrated both abroad and at home than Hobbes. In our times, he is much neglected: a lively instance how precarious all reputations founded on reasoning and philosophy! A pleasant comedy which paints the manners of the age, and exposes a faithful picture of nature, is a durable work, and is transmitted to the latest posterity. But a system, whether physical or metaphysical, owes commonly its success to its novelty; and is no sooner canvassed with impartiality, than its weakness is discovered." Like the majority of literary prophecies dictated by feeling and not by impartial criticism, this one, whether as it refers to "The Leviathan," of which it is ostensibly uttered, or to the "Treatise of Human Nature," the fate of which doubtless suggested it, has proved untrue. The influence of Hobbes has revived, as that of the Treatise remained undiminished from the time when it was first fully appreciated. And in both cases their influence has arisen from that element which seems alone to be capable of giving permanent value to metaphysical thought. It is not that in either case the fundamental theory of the author is adopted, as the disciples of old imbibed the system of their masters, but that each has started some novelties in thought, and, either by themselves sweeping away prevailing fallacies, or suggesting to others the means of doing so, have cleared the path of philosophy. As a general system, the philosophy of Hobbes has been perhaps most completely rejected at those times when its incidental discoveries and suggestions made it most serviceable to philosophy, and were the cause of its being most highly esteemed. "Harm I can do none," says Hobbes, when speaking of the metaphysicians who preceded him, "though I err not less than they, for I leave men but as they are, in doubt and dispute." There is indeed nothing in the later history of metaphysical writing to show that the triumphs in that department of thought are to stretch beyond the establishment of incidental truths, the removal of fallacies, and the suggestion of theories that may teach men to think. The field is a republic: incidental merit has its praise, and is allowed its pre-eminence; but no one mind, it may safely be pronounced, holds in it that monarchical sway which Adam Smith retains over the empire of political economy. The ancient systems anterior to Christianity allowed of such empire. The pupil did not follow his master merely in this and that incidental truth developed, but adopted the system in all its details and proportions as his system and his creed. In later times it
