‘If no‐one questions me’, said St. Augustine in his Confessions, ‘I know, but if I am required to explain my point of view I do not know.’ I understand exactly what he means. When Maurice Line suggested that I should speak this evening I was confident and accepted, but when I began to consider what I should say and asked myself the questions, I realized that I did not know, and looking at the names of those who were also speaking I had to assure myself that I had been invited as a non‐expert, a non‐social scientist—but that was as far as I dared go or I should have argued myself out of existence rapidly.
