What, then, was it that drove Burke to a position so markedly at variance with the idealism of his later years? In all probability it was his rooted suspicion of reasoning as a deliberate and conscious process. Other writers of the century--Addison, for instance--had spoken as if men reasoned from certain abstract ideas (proportion, fitness, and the like) to individual instances of beauty, deciding a thing to have beauty or no, according as it squared or failed to square with the general notion This, as Burke points out, is more than questionable in itself, and it was certain to affront a man who, even thus early, had shown an almost morbid hatred of abstractions. In his later years, as is well known, he sought refuge from them in instinct, in "prejudice", in the unconscious working of the "permanent reason of man". In earlier days--he was still well under thirty--he found escape by the grosser aid of a materialist explanation (Burke's treatise was published in 1756 The _Laocoon_ of Lessing, a work which may be compared with that of Burke and which was very probably suggested by it, appeared in 1766.)] But none can deny the skill with which he works out his theory, nor the easy mastery with which each part is fitted into its place. The speculative power of the book and the light it throws on the deeper springs of the imagination are alike memorable. The first is not unworthy of the _Reflections_ or the _Appeal from the New to the Old Whigs_; the second shows that fruitful study of the Bible and the poets, English and classical, to which his later writings and speeches bear witness on every page. If the originality and depth of Burke's treatise is to be justly measured, it should be set side by side with those papers of Addison which Akenside expanded in his dismal _Pleasures of the Imagination_. The performance of Addison, grateful though one must be to him for attempting it, is thin and lifeless. That of Burke is massive and full of suggestion. At every turn it betrays the hand of the craftsman who works with his eye upon his tools. The speculative side of criticism has never been a popular study with Englishmen, and it is no accident that one of the few attempts to deal seriously with it should have been made at the only time when philosophy was a living power among us, and when the desire to get behind the outward shows of things was keener than it has ever been before or since. But for Burke's treatise, a wide gap would have been left both in the philosophy and the criticism of the eighteenth century; and it is to be wished that later times had done more to work the vein which he so skilfully explored. As it is, the writers both of France and Germany--above all, Hegel in his _Aesthetik_--have laboured with incomparably more effect than his own countrymen, Mr. Ruskin excepted, upon the foundations that he laid.
