His theories on society were fashionable 200 years ago, so why are British politicians such fans of this New York Times columnist’s new book? When David Brooks was a boy, he had two turtles named Gladstone and Disraeli. How come? “There’s a New York Jewish culture that has a saying ‘Think Yiddish, act British’,” says Brooks. “My background was filled with Anglophile Jews. Jews of a certain generation, really my grandfathers’ generation, gave each other names they thought would help them fit in – Irving, Sydney, Milton and Norman – and now in the US those are not English names any more, they’re Jewish names. And I was brought up in that culture. Hence the turtles.” Hence much more than that. Brooks, though a 49-year-old Canadian-born, suburban New York-raised, Chicago university-educated and now so much of a stellar New York Times columnist that the White House sometimes rings him to ask what he’s planning to write about, is deeply Anglophilic. “I am very British in that I’m reticent. There’s a survey of how many times people in different countries touch each other during an hour over coffee. In Rio it was 180, in Paris 120. London, zero.” How about new York? “Maybe 40? I feel very at home here.” We’re sitting in the Cinnamon Club, an Indian restaurant in Westminster frequented by policy wonks, and he looks more diffident than the only Englishman at our table.

His new book, The Social Animal: A Story of How Success Happens, is steeped in the anti-rationalist philosophical reflections of the British Enlightenment. And this is no ordinary book: even before publication this week it has become, according to Times columnist Rachel Sylvester, “the must-read text for politicians searching for a new prism through which to examine the apparently intractable challenges of social immobility, school dropout rates, welfare dependency and crime”. Education secretary Michael Gove believes it contains vital clues for turning around failing schools; universities minister David Willetts reckons it may help define modern Conservatism; policy minister Oliver Letwin thinks it articulates the cherished Tory notion of the Big Society. The book is so hot that both David Cameron and Ed Miliband are meeting Brooks this week, and Steve Hilton, the PM’s top strategist, has invited him to hold a
