"This celebrated book has been in print for over half a century. It’s a historical account of the fanatical millenarian sects that swept across Europe from the 11th to 15th centuries: sects that were driven by certainty of the world coming to an end. Clearly, it has relevance for our times. And when the world ended there would be deliverance for the elect. Your enemies would be damned just as you would be saved. These sects were extremely violent, and they came from the poorest, most deprived, marginal sections of society. They surged across Northern Germany, killing Jews, priests, the bourgeois. Frank Kermode, in his famous book The Sense of an Ending , elaborated on Cohn’s masterwork by suggesting that actually it’s very common for all of us – especially artists – to feel that we live at the end of times, and that our own demise means all the more to us because we’re not simply dying in the middle of the plot, in medias res . Our lives take on significance because as we decline we notice our society is declining all around us. It’s part of a yearning for narrative significance. As Kermode said, no one can hear a clock saying, as it does, tick tick . What we hear is tick tock . A beginning and an end. We impose this order. Cohn’s book found its way into conversations in On Chesil Beach , and it’s present in Solar , when Beard reflects sceptically on the environmental movement. The epigraph to Solar is a quote from Rabbit is Rich , in which Rabbit is pleased to note that the Earth is decaying, just as he himself is. We’re bound to ask ourselves, if we’re thinking of matters like climate change, whether we are indulging our time-honoured tendency for end-time thinking. Of course, even if we are, that doesn’t make climate change any less real. In On Chesil Beach it’s raised within the context of a discussion of the nuclear arms race: the fear that the Earth could be obliterated in a matter of hours. And again, we do now have the technological capability to destroy ourselves – whereas in medieval times the imagined destruction had supernatural causes. It was God’s revenge. The other reason I mention this book is because in its final section, in what I think are rather resounding pages, Cohn notes that this European tradition of end-time thought fades after the 15th century, or at least becomes less bloody, then re-emerges in the 20th century in secular form, in two great totalitarian movements which derive their momentum from the millennial of the Middle Ages . One of these was Nazism, with its deliberate echoes of the Book of Revelation – the thousand year Reich. The Aryan master race will be the elect, the saved, while the Jews would be damned. And again in Soviet communism: the State will wither away, the proletariat will be the elect, the enemies – the bourgeois, the kulaks – will be destroyed. Again there is a sense of deliverance through blood and fire. We now live in a kind of dazed, post-totalitarian world. You see little reawakenings, in the more extravagant and radical forms of Islam, and in even tinier groups within Christianity. But basically those two great movements consumed so many in the fire that we’re still recovering – the smoke still hangs in the air. So we have nothing, and we are lucky to have nothing. Those grim utopian movements defined the 20th century in its first half. Whatever progress we make now, we’ll have to achieve it in small steps. Well, I see it through the sceptical eyes of Isaiah Berlin . Always distrust utopian thinkers. People who believe they can deliver us to happiness for ever are bound to think, rationally enough, that the means will justify the ends. If it will bring the peaceable kingdom to pass, then break the eggs to make that everlasting omelette! And I think utopian radical Islamism or jihadism is a smaller and more scattered version of what so powerfully dominated the 20th century. The jihadi preference for instant rage, slaughter and martyrdom repels everyone, including nearly all Muslims. And the list of radical Islamist dislikes is too long, too much against the grain of human aspiration for their cause to have much appeal in the long run – sexuality, free thought, music, gays, evolutionary biology, unveiled independent women, pluralism, democracy, curiosity, fun, tolerance, fashion, humour… Get the weekly Five Books newsletter I saw a demonstration along the Euston Road in London the other day – about a hundred chanting fellows in beards, with the women well to the rear, as you’d expect, head to toe in burqas, and many carrying banners demanding ‘Sharia law now’. The rush-hour traffic was edging round them; no one was paying much attention. They were a minor nuisance, like a failed traffic light. They didn’t look threatening so much as comically hopeless. How marvellous: no one was shouting or throwing stones at them, no one was much bothered. They were exercising their well-protected (I hope) right to demonstrate. A right they would surely never grant to others, if they had their way. They seemed not only puny but politically illiterate – some of their banners said ‘Hands off Gaddafi’. Well, he’s been a scourge to Islamists in his own country, so how on earth they thought he was someone they would want to support, I don’t know. Politics belong in novels when novelists want it. If you were, let’s say, a Polish dissident writer in the 70s and 80s, you wouldn’t feel you had much freedom not to address your situation. But in our relatively settled polis in England there are people writing every conceivable kind of novel. No one is criticised for not writing about the banking crisis or cuts to the Arts Council. It’s a luxury and a freedom to let your mind go wherever it wants. Israeli and Palestinian writers do not have this freedom. It’s a conscious and hard choice to ignore the ‘situation’."
