A twentieth-century intellectual of the first rank presents the case for the nineteenth-century aesthetician whose elegant subversions delivered us to modernism. Walter Pater (1839-1894) was an obscure Oxford don until 1873, when his first book, The Renaissance, exposed his argument favoring sensation over thought and, in doing so, ignited a hard, gem-like flame. "Say not what it is but what it makes you see - or feel" is not something Pater ever said, but it will suffice as an encapsulation of an attitude that moved the authority of a work of art from the object to the subject, subsequently outraging the defenders of perceived truth of his time and making Pater himself a figure of controversy and even ridicule. Substituting sensationalism for sensation and reading Pater's claim for hedonism, or pleasures the soul might savor, as outright decadence, Pater's detractors far outnumbered and outranked his followers (including his fellow Oxonian and most notorious devotee, Oscar Wilde). But ever since Pater has proved, at least in the high arts, the decisive victor of the revolution he set into motion.
