I hadn’t read much John Updike when I picked up Nicholson Baker’s book on him during lockdown; but then neither had Baker when he wrote the book. This is one of the novelties of U and I. Where most non-fiction strives for mastery of its subject, this little book pursues that ‘very spottiness of coverage [that] is, along with the wildly untenable generalizations that spring from it, one of the most important features of the thinking we do about living writers’. The result is a funny, profound meditation on what writers actually mean to readers as opposed to what academics tell us they should mean.
