“My late colleague Joseph Brodsky, who died in 1996, used to appall his students by requiring them to memorize something like a thousand lines each semester. He felt he was preparing them for the future; they might need such verses later in life. His own biography provided a stirring example of the virtues of mental husbandry. He’d been grateful for every scrap of poetry he had in his head during his enforced exile in the Arctic, banished there by a Soviet government that did not know what to do with his genius and that, in a symbolic embrace of a national policy of brain drain, expelled him from the country in 1972.
Brodsky was a nonpareil in various ways, not least in being the only teacher I knew who continued to smoke during class as the air-purifying nineties rolled around. He loved to recite poetry. The words emerged through smoke, and a thick Russian accent, but the conviction and import were unmistakable: to take a poem to heart was to know it by heart.
I’m struck by how, in the seventeen years since his death, the meaning and justifications for verse memorization have shifted. The effort in its acquisition may be the same, but we’d be naïve to suppose the necessity behind it is unaltered.
Memorized poems are a sort of larder, laid up against the hungers of an extended period of solitude. But today we are far less solitary than we were even a few years ago. Anyone equipped with a smartphone—many of my friends would never step outdoors without one—commands a range of poetry that beggars anything the brain can store. Let’s say it’s a gorgeous afternoon in October. You’re walking through a park, and you wish to recall—but can’t quite summon—the opening lines of Keats’ “To Autumn.” With a quick tap-tap-tap, you have it on your screen. You’re back in the nineteenth century, but you’re also in the twenty-first, where machine memory regularly supplants and superannuates brain memory.
So why undergo the laborious process of memorizing a poem these days, when—tap, tap, tap—you have it at your fingertips? Has this become another outmoded practice? When I was a Boy Scout, in the sixties, I spent some hours trying to learn Morse code and even, on a couple of overly sunny, headachey afternoons, trying to communicate by flag semaphore. Some things were meant to disappear. (And many of my students wish that assignments to memorize poems would follow them.)
The best argument for verse memorization may be that it provides us with knowledge of a qualitatively and physiologically different variety: you take the poem inside you, into your brain chemistry if not your blood, and you know it at a deeper, bodily level than if you simply read it off a screen. Robson puts the point succinctly: “If we do not learn by heart, the heart does not feel the rhythms of poetry as echoes or variations of its own insistent beat”
