We may here remark, that Mr. Arnold's statement of his principles is open to some misinterpretation,--an accident against which he has, perhaps, not sufficiently guarded it. For many persons the word _practical_ is almost identical with the word _useful_, against which, on the other hand, they erect the word _ornamental_. Persons who are fond of regarding these two terms as irreconcilable, will have little patience with Mr. Arnold's scheme of criticism. They will look upon it as an organised preference of unprofitable speculation to common sense. But the great beauty of the critical movement advocated by Mr. Arnold is that in either direction its range of action is unlimited. It deals with plain facts as well as with the most exalted fancies; but it deals with them only for the sake of the truth which is in them, and not for _your_ sake, reader, and that of your party. It takes _high ground_, which is the ground of theory. It does not busy itself with consequences, which are all in all to you. Do not suppose that it for this reason pretends to ignore or to undervalue consequences; on the contrary, it is because it knows that consequences are inevitable that it leaves them alone. It cannot do two things at once; it cannot serve two masters. Its business is to make truth generally accessible, and not to apply it. It is only on condition of having its hands free, that it can make truth generally accessible. We said just now that its duty was, among other things, to exalt, if possible, the importance of the ideal. We should perhaps have said the intellectual; that is, of the principle of understanding things. Its business is to urge the claims of all things to be understood. If this is its function in England, as Mr. Arnold represents, it seems to us that it is doubly its function in this country. Here is no lack of votaries of the practical, of experimentalists, of empirics. The tendencies of our civilisation are certainly not such as foster a preponderance of morbid speculation. Our national genius inclines yearly more and more to resolve itself into a vast machine for sifting, in all things, the wheat from the chaff. American society is so shrewd, that we may safely allow it to make application of the truths of the study. Only let us keep it supplied with the truths of the study, and not with the half-truths of the forum. Let criticism take the stream of truth at its source, and then practice can take it half-way down. When criticism takes it half-way down, practice will come poorly off.
