It is as a master of rhetoric that De Quincey is distinguished among writers. Some hints of his ability are seen in the opening and closing passages of this essay, but to find him at his best one must turn to the _Confessions_ and to the other papers which describe his life, particularly those which recount his marvellous dreams. In these papers we find the passages where De Quincey's passion rises to the heights which few other writers have ever reached in prose, a loftiness and grandeur which is technically denominated as "sublime." In his _Essay on Style_, published in _Blackwood's_, 1840, he deprecates the usual indifference to form, on the part of English writers, "the tendency of the national mind to value the matter of a book not only as paramount to the manner, but even as distinct from it and as capable of a separate insulation." As one of the great masters of prose style in this century, De Quincey has so served the interests of art in this regard, that in his own case the charge is sometimes reversed: his own works are read rather to observe his manner than to absorb his thought. Yet when this is said, it is not to imply that the material is unworthy or the ideas unsound; on the contrary, his sentiment is true and his ideas are wholesome; but many of the topics treated lie outside the deeper interests of ordinary life, and fail to appeal to us so practically as do the writings of some lesser men. Of the "one hundred and fifty magazine articles" which comprise his works, there are many that will not claim the general interest, yet his writings as a whole will always be recognized by students of rhetoric as containing excellences which place their author among the English classics. Nor can De Quincey be accused of subordinating matter to manner; in spite of his taste for the theatrical and a tendency to extravagance, his expression is in keeping with his thought, and the material of those passages which contain his most splendid flights is appropriate to the treatment it receives. One effective reason, certainly, why we take pleasure in the mere style of De Quincey's work is because that work is so thoroughly inspired with the Opium-Eater's own genial personality, because it so unmistakably suggests that inevitable "smack of individuality" which gives to the productions of all great authors their truest distinction if not their greatest worth.
