At dinner on Friday evening, one story I recounted of my undergraduate days was when I gave a paper in a class on political theory. The students in those days tended to be very much on the left. I was in a class with a load of Marxists – they could quote Marx at length, but once one got beyond that they were completely lost. I had been asked to speak on Conservatism. I did not confine my analysis to British Conservatism, but put it in a wider context. This took some time. Indeed, I think I spoke for about 45 minutes. When I finished, the tutor asked if there were any questions. There was silence. It lasted for ages, until one student eventually piped up. ‘Do you actually believe all that?’ That was the totality of the questions.
