From The Boston Globe:
In 1846, Charles Baudelaire wrote a little essay called “What is the Good of Criticism?” This is a question that virtually every critic asks herself at some point, and that some have answered with hopelessness, despair, even self-loathing. Baudelaire didn’t think that criticism would save the world, but he didn’t think it was a worthless pursuit, either. For Baudelaire, criticism was the synthesis of thought and feeling: in criticism, Baudelaire wrote, “passion . . . raises reason to new heights.” A few years later, he would explain that through criticism he sought “to transform my pleasure into knowledge”—a pithy, excellent description of critical practice. Baudelaire’s American contemporary Margaret Fuller held a similar view; as she put it, the critic teaches us “to love wisely what we before loved well.”
By “pleasure” and “love” Baudelaire and Fuller didn’t mean that critics should write only about things that make them happy or that they can praise. What they meant is that a critic’s emotional connection to an artist, or to a work of art, is the sine qua non of criticism, and it usually, therefore, determines the critic’s choice of subject. Who can doubt that Edmund Wilson loved literature—and that, to him, it simply mattered more than most other things in life? Who can doubt that Pauline Kael found the world most challenging, most meaningful—hell, most alive—when she sat in a dark movie theater, or that Kenneth Tynan felt the same way at a play? For these critics and others—those I would consider at the center of the modern tradition—cultivating this sense of lived experience was at the heart of writing good criticism. Randall Jarrell, certainly no anti-intellectual, wrote that “criticism demands of the critic a terrible nakedness . . . All he has to go by, finally, is his own response, the self that makes and is made up of such responses.” Alfred Kazin agreed; the critic’s skill, he argued, “begins by noticing his intuitive reactions and building up from them; he responds to the matter in hand with perception at the pitch of passion.”
