The function of criticism is the reeducation of perception of works of art; it is an auxiliary in the process, a difficult process, of learning to see and hear. The conception that its business is to appraise, to judge in the legal and moral sense, arrests the perception of those who are influenced by the criticism that assumes this task. The moral office of criticism is performed indirectly. The individual who has an enlarged and quickened experience is one who should make for himself his own appraisal. . .The moral function of art itself is to remove prejudice, do away with the scales that keep the eye from seeing, tear away the veils due to wont and custom, perfect the power to perceive. The critic’s office is to further this work, performed by the object of art.
