It is scarcely to be wondered at if criticism is not very precise, not very exact in the use of its terms, when it has to work at such a disadvantage. Since we can never speak of a book with our eye on the object, never handle a book--the real book, which is to the volume as the symphony to the score--our phrases find nothing to check them, immediately and unmistakably, while they are formed. Of a novel, for instance, that I seem to know well, that I recall as an old acquaintance, I may confidently begin to express an opinion; but when, having expressed it, I would glance at the book once more, to be satisfied that my judgement fits it, I can only turn to the image, such as it is, that remains in a deceiving memory. The volume lies before me, no doubt, and if it is merely a question of detail, a name or a scene, I can find the page and verify my sentence. But I cannot catch a momentary sight of the book, the book itself; I cannot look up from my writing and sharpen my impression with a straight, unhampered view of the author's work; to glance at a book, though the phrase is so often in our mouths, is in fact an impossibility. The form of a novel--and how often a critic uses that expression too--is something that none of us, perhaps, has ever really contemplated. It is revealed little by little, page by page, and it is withdrawn as fast as it is revealed; as a whole, complete and perfect, it could only exist in a more tenacious memory than most of us have to rely on. Our critical faculty may be admirable; we may be thoroughly capable of judging a book justly, if only we could watch it at ease. But fine taste and keen perception are of no use to us if we cannot retain the image of the book; and the image escapes and evades us like a cloud.
