From the myths of the Old Testament to the miracles of the New, the Bible has been as much a source of inspiration to writers, artists and composers as it has to theologians and priests. One of the most infamous yet influential of all Old Testament myths is that of the Destruction of Sodom, which has inspired writers from the Earl of Rochester to Proust, painters from Dürer to Turner, and film-makers from Pier Paolo Pasolini to Robert Aldrich.

For as long as I can remember, and long before I set foot in America for the first time at age 24, I have been intrigued by America – the “idea” of it, conjured up through music, and, as it turned out, the reality – and the common language which (depending on your point of view) binds us, or separates us.

All the great sociologists, in the tradition of Georg Simmel, Max Weber and others, are on a mission. They cannot help wishing to change the world. Science should be value-free, but the social sciences have never come close to that questionable ideal. All science is a human endeavour, indeed always one rooted in society. There is no position, theoretical or descriptive, that will or cannot change, or that isn’t subject to paradigm or point-of-view, perspectives that are rooted in time and place.

In 1982 Antony Sher played the Fool to Michael Gambon’s King in the Royal Shakespeare Company’s production of King Lear. Shortly after, he came back to Stratford to play Richard III, for which he won the Olivier and Evening Standard Awards for Best Actor.

My heroine would not have appeared in a Jane Austen novel. Brilliant, arch and incisive though Austen was – as deft in dissecting the economics of romance as in laying bare the lies told by the human heart – for better or worse, she still sent all her heroines down the aisle.

All this time La Mer had been brewing.

When I was 23 I had a job selling butterflies in glass cases in America. I worked for a guy who, as well as being a butterfly salesman, had ambitions to be America’s first Pope (an ambition he ditched on account of him wanting to marry). I drove all over the US and sold in 32 states. It was 1987 and was pre-internet and pre-mobile phone, which increased the sensation of having an adventure in a land far, far away.

In our era of 24/7 news, downloadable from anywhere in the world at the touch of an app, it's hard to remember that not so very long ago the agenda was set by the BBC - the Home Service as Radio 4 was then called, and BBC TV, just the one channel, which broadcast news at a handful of fixed points during the evening. Outside broadcasts, "OBs", were slow, labour-intensive and expensive. Politicians were respected.

La Belle Sauvage, the first instalment of Philip Pullman’s eagerly-awaited new trilogy The Book of Dust, opens in the Trout, a rambling Thames-side pub on the outskirts of Port Meadow, north of Oxford. Here all kinds drink: scholars, labourers, watermen; gossip and taunts are exchanged over the bar; peacocks stalk the river terrace, haranguing customers to privilege them with snacks.

A long time ago when I was very young, a voice hidden deep within me whispered, "Don’t take anything for granted. Go and see for yourself." This little nagging murmur has led me to so many journeys, so many explorations, trying to live together multiple lives, from the sublime to the ridiculous. Always the need has been to stay in the concrete, the practical, the everyday, so as to find hints of the invisible through the visible.
