Harper's Magazine features Wyatt Mason's review of John Updike's stupendous output as a literary critic.
To peruse copies of books that Updike read with the intention of reviewing ... is to meet a reader who, in a most inarguable way, is a picture of thoroughness. The margins run with comments, even in appendices, even by footnotes. “I read slower than I write,” Updike wrote, rather amazingly, in 1975, suggesting that these annotative efforts represent a substantial investment of time. If criticism is, as Terry Eagleton has said, a way of “looking at meaning not as an object but as a practice,” then one can see in Updike’s review copies the humble, rudimentary motions of that practice. As often as not, his marginalia may be seen doing one of the most immediate jobs of criticism, which is to distinguish, however arbitrarily, good things from bad. And yet, in the main, Updike may be spied undertaking a more considered task: that of interrogation. The form of punctuation that predominates in his margins is the question mark. What one is witness to is a patient reader’s private conversation with a book.
