Had Mr. Wordsworth's poems been the silly, the childish things which they were for a long time described as being; had they been really distinguished from the compositions of other poets merely by meanness of language and inanity of thought; had they indeed contained nothing more than what is found in the parodies and pretended imitations of them; they must have sunk at once, a dead weight, into the slough of oblivion, and have dragged the preface along with them. But year after year increased the number of Mr. Wordsworth's admirers. They were found, too, not in the lower classes of the reading public, but chiefly among young men of strong sensibility and meditative minds; and their admiration (inflamed perhaps in some degree by opposition) was distinguished by its intensity, I might almost say, by its religious fervour. These facts, and the intellectual energy of the author, which was more or less consciously felt, where it was outwardly and even boisterously denied, meeting with sentiments of aversion to his opinions, and of alarm at their consequences, produced an eddy of criticism, which would of itself have borne up the poems by the violence with which it whirled them round and round. With many parts of this preface, in the sense attributed to them, and which the words undoubtedly seem to authorize, I never concurred; but, on the contrary, objected to them as erroneous in principle, and as contradictory (in appearance at least) both to other parts of the same preface and to the author's own practice in the greater number of the poems themselves. Mr. Wordsworth, in his recent collection, has, I find, degraded this prefatory disquisition to the end of his second volume, to be read or not at the reader's choice. But he has not, as far as I can discover, announced any change in his poetic creed. At all events, considering it as the source of a controversy, in which I have been honoured more than I deserve by the frequent conjunction of my name with his, I think it expedient to declare, once for all, in what points I coincide with his opinions, and in what points I altogether differ. But in order to render myself intelligible, I must previously, in as few words as possible, explain my ideas, first, of a poem; and secondly, of poetry itself, in kind and in essence. The office of philosophical disquisition consists in just distinction; while it is the privilege of the philosopher to preserve himself constantly aware that distinction is not division. In order to obtain adequate notions of any truth, we must intellectually separate its distinguishable parts; and this is the technical process of philosophy. But having so done, we must then restore them in our conceptions to the unity in which they actually co-exist; and this is the result of philosophy.
