“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 which 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.” – Matthew Arnold, “The Function of Criticism at the Present Time”
