In criticism, these are elementary laws; but they never can be popular, and in this country they have been very little followed, and one meets with immense obstacles in following them. That is a reason for asserting them again and again. Criticism must maintain its independence of the practical spirit and its aims. Even with well-meant efforts of the practical spirit, it must express dissatisfaction, if in the sphere of the ideal they seem impoverishing and limiting. It must not hurry on to the goal because of its practical importance. It must be patient, and know how to wait; and flexible, and know how to attach itself to things and how to withdraw from them. It must be apt to study and praise elements that for the fulness of spiritual perfection are wanted, even though they belong to a power that in the practical sphere may be maleficent. It must be apt to discern the spiritual shortcomings or illusions of powers that in the practical sphere may be beneficent. And this without any notion of favoring or injuring, in the practical sphere, one power or the other; without any notion of playing off, in this sphere, one power against the other. When one looks, for instance, at the English Divorce Court,--an institution which perhaps has its practical conveniences, but which in the ideal sphere is so hideous; an institution which neither makes divorce impossible nor makes it decent; which allows a man to get rid of his wife, or a wife of her husband, but makes them drag one another first, for the public edification, through a mire of unutterable infamy,--when one looks at this charming institution, I say, with its crowded trials, its newspaper reports, and its money compensations, this institution in which the gross unregenerate British Philistine has indeed stamped an image of himself, one may be permitted to find the marriage theory of Catholicism refreshing and elevating. Or when Protestantism, in virtue of its supposed rational and intellectual origin, gives the law to criticism too magisterially, criticism may and must remind it that its pretensions, in this respect, are illusive and do it harm; that the Reformation was a moral rather than an intellectual event; that Luther's theory of grace no more exactly reflects the mind of the spirit than Bossuet's philosophy of history reflects it; and that there is no more antecedent probability of the Bishop of Durham's stock of ideas being agreeable to perfect reason than of Pope Pius the Ninth's. But criticism will not on that account forget the achievements of Protestantism in the practical and moral sphere; nor that, even in the intellectual sphere, Protestantism, though in a blind and stumbling manner, carried forward the Renaissance, while Catholicism threw itself violently across its path.
