That is a Mary Beard feature in the 3 June 2016 edition of the Times Literary Supplement. Various luminaries were asked what they thought of Brexit. My favorite answer came from Colm Tóibín:
The European Union, despite its flaws, or perhaps because of them, is a wholly rational institution. Like most of us, it is in constant need of urgent reform and can handle anything except a crisis. Even though it is deeply secular, the EU has performed miracles. It has allowed France and Germany to move close to each other; it has allowed Irish and British ministers to meet as equals, which the Irish have enjoyed. It can also make us laugh — the group photographs of the EU leaders after their meetings and the antics of the European Parliament are wholly ludicrous…
More brutal was Jan Morris:
Being politically in or out of Europe has had no impact at all on my own work, and I have no idea what it’s done for or to the cultural life of Britain. For myself, I have long argued for a federal Britain within a federal Europe, but it was always a dream anyway, and I’ve woken up now. If reasons you require, look around you!
Declan Kiberd had a good point:
They [the English] realized that in some ways England’s was an immensely stressed society, whose people had been so distracted by the British cultural project that they still faced an unresolved identity question of their own. It’s a long time since Bernard Shaw described England as the last, most fully penetrated of the British colonies — which could be why its people feel such ambivalence about the more recent transnational scheme.
I do recommend that you all subscribe to the TLS. If you would like yet another point of view, from Dissent, here is Richard Tuck with the Left case for Brexit.
