Some people did rather well in lockdown and mastered French, or needlepoint, or read all 75 Maigret novels. Me, I watched old television, most of it courtesy of the BBC archive – anyone heard of Sir Mortimer Wheeler, who did some terrific programmes on archaeology? They included a funny quiz show featuring distinguished archaeologists called Animal, Vegetable, Mineral? Alas, the archive offers just a few programmes from each series.

One of the best was Face to Face, a series of half-hour interviews by the politician-broadcaster John Freeman, with distinguished figures of the 1950s and 1960s – Martin Luther King, Edith Sitwell, Evelyn Waugh (who said the reason he was taking part was that he was broke) – and Carl Jung.

I knew little about Jung except a recollection that he was more mystical than Freud. But, as this half-hour interview from 1959 showed, he was fascinating: a Swiss pastor’s son who studied medicine, then psychiatry, because he couldn’t afford archaeology. He was shrewd and humorous. When Freeman asked whether he believed in God – as he did with many interviewees – Jung said, “I don’t believe; I know.” (He had a problem with the concept of belief once he’d accepted an hypothesis – “If I know a thing, I don’t believe it.”)
