Perhaps, I mused, it was a general feeling that the EU was about openness, tolerance and diversity. But they must surely know that the EU’s rules on free movement mean a highly discriminatory regime, one that makes it much more difficult for people from outside the EU to get into Britain – even though we need their skills.

So what was it about? People’s emotions matter, even when they do not seem to be wholly rational. The feelings being manifested outside my house are shared by the large numbers of people – 30,000, they say – who at the weekend came together in Trafalgar Square to hear pro-EU speeches by Sir Bob Geldof. There is, among a section of the population, a kind of hysteria, a contagious mourning of the kind that I remember in 1997 after the death of the Princess of Wales. It is not about the EU, of course; or not solely. A great many of these protesters – like dear old Geldof – are in a state of some confusion about the EU and what it does.
