A century from now, a literature scholar pieces together a picture of our times in a novel that quietly compels us to consider the moral consequences of global catastrophe

The sheer Englishness of Ian McEwan’s fiction may not be fully visible to his English readers. But it is clearly, and amusingly, visible to at least this Irish reader. It isn’t just McEwan’s elegiac, indeed patriotic, attentiveness to English landscapes – to the wildflowers and hedgerows and crags, to the “infinite shingle” of Chesil Beach, to the Chilterns turkey oak in the first paragraph of Enduring Love. Nor is it merely the ferocious home counties middle-classness of his later novels, in which every significant character is at the very least a neurosurgeon or a high court judge, everyone is conversant with Proust, Bach and Wordsworth, and members of the lower orders tend to appear as worrying upstarts from a world in which nobody plonks out the Goldberg Variations on the family baby grand. No, McEwan’s Englishness has most to do with his scrupulously rational, but occasionally and endearingly purblind, liberal morality: England’s most admirable, and most irritating, gift to politics and art.

These thoughts were provoked by a brief passage in McEwan’s future-set new novel that describes the “Inundation” of Britain after a Russian warhead goes off accidentally in the middle of the Atlantic, causing a tsunami that, combined with rising sea levels, wipes out everything but a Europe-wide archipelago of mountain peaks. In these entertainingly nihilistic pages, the fate of that other major chunk of the British Isles is not mentioned. Presumably Ireland, with its dearth of high peaks, fared badly as Europe drowned. But from McEwan’s future history, you’d never know it. I began to think of What We Can Know as another of McEwan’s deeply English stories. It has, I thought, the familiar partialities of vision. Has Brexit, endlessly backstopped by those pesky six counties, taught English liberals nothing?
