I might have had a more glittering Oxford career, but I had little money to spare and would have been hard put to make ends meet if it had not been for a number of modest grants secured for me from the college at the instance of my ever-helpful tutor, the chemist Dorothy Hodgkin. I was also assisted by some educational trusts. I might have been able to supplement my income further from such sources if I had been prepared to give an undertaking to go into teaching. But I knew I had no such calling; and I did and do believe that good teachers need a vocation which most people just do not have. In fact, I did teach science for one vacation at a school in Grantham in the summer of 1944: this earned the money for that luxury in Grantham but near-necessity in Oxford — a bicycle. It was while I was teaching there that Paris was liberated. The headmaster called the school together, announced that Paris was free again and told us how the brave Resistance fighters had helped the Allies by rising up against the German occupiers. It was a thrilling moment. The war was evidently being won; I felt somehow less guilty for not being able to play a larger part; and I shared the joy of the British people that the French Resistance had restored French honour and pride. We may have had an exaggerated view in those days of the universality of resistance — we told each other stories of how the customers of a cafe would tap out ‘V for Victory’ in morse code on their glasses when a German soldier entered the cafe — but we had no doubt that every true Frenchman wanted to be free.
I threw myself into intensely hard work. In Dorothy Hodgkin the college was fortunate to have a brilliant scientist and a gifted teacher, working in the comparatively new field of X-ray crystallography. Mrs Hodgkin was a Fellow of the Royal Society and later made a decisive contribution towards discovering the structure of penicillin, the first antibiotic — work for which she won the Nobel Prize in 1964. (Penicillin itself had been discovered and given its first trials in the Radcliffe Infirmary, which stands just beside Somerville, two years before I went up to Oxford.) In my fourth and final year (1946–47) I worked with a refugee German scientist, Gerhard Schmidt, under Dorothy Hodgkin’s direction, on the simple protein Gramicidin B as the research project required to complete Part II of my chemistry course. Through the Cosmos Club and the Scientific Club I also came across other budding young scientists and heard many well-known scientists speak, including J.D. Bernal. His politics were very left wing, as indeed were those of many other scientists at that time. But they would never have dreamt of carrying their politics over into their professional relationships with their students.
Religion also figured large in my Oxford life. There are many tales of young people entering university and, partly through coming into contact with scepticism and partly for less wholesome reasons, losing their faith. I never felt in any danger of that. Methodism provided me with an anchor of stability and, of course, contacts and friends who looked at the world as I did. I usually attended the Wesley Memorial Church on Sundays. There was, as in Grantham, a warmth and a sober but cheerful social life which I found all the more valuable in my initially somewhat strange surroundings. The church had a very vigorous Students’ Fellowship. After Sunday Evening Service there was usually a large gathering over coffee in the minister’s house, where there would be stimulating discussion of religious and other matters. Occasionally I would go to the University Church of St Mary the Virgin to listen to a particularly interesting university sermon — though that church has about it a certain ‘official’ formality which makes it a somewhat cold place of worship. Sometimes I would go to the college chapel, especially when I knew that Miss Helen Darbishire, who was Principal and a distinguished scholar of Milton and Wordsworth when I first went up to Somerville, was preaching.
Generally speaking, though, I did not go to Anglican churches. But oddly enough — or perhaps not so oddly when one considers the great impact he had on so many of my generation — it was the religious writing of that High Anglican C.S. Lewis which had most impact upon my intellectual religious formation. The power of his broadcasts, sermons and essays came from a combination of simple language with theological depth. Who has ever portrayed more wittily and convincingly the way in which Evil works on our human weaknesses than he did in The Screwtape Letters? Who has ever made more accessible the profound concepts of Natural Law than he did in The Abolition of Man and in the opening passages of Mere Christianity? I remember most clearly the impact on me of Christian Behaviour (republished in Mere Christianity, but originally appearing as radio talks). This went to the heart of the appalling disparity between the way in which we Christians behave and the ideals we profess. One of C.S. Lewis’s messages was that the standards of Christianity are not just binding on the saints. As he put it:
Perfect behaviour may be as unattainable as perfect gear-changing when we drive; but it is a necessary ideal prescribed for all men by the very nature of the human machine just as perfect gear-changing is an ideal prescribed for all drivers by the very nature of cars.
Similarly, I was helped by what he wrote of the application of that sublime principle of Christian charity which seems to most of us so impossible of fulfilment. Lewis did not for a moment contest or diminish the sublimeness; but he very helpfully set out what charity is not.
…what [does] loving your neighbour as yourself [mean?] I have to love him as I love myself. Well, how exactly do I love myself? Now that I come to think of it, I have not exactly got a feeling of fondness or affection for myself, and I do not even always enjoy my own society. So apparently ‘Love your neighbour’ does not mean ‘feel fond of him’ or ‘find him attractive’… I can look at some of the things I have done with horror and loathing. So apparently I am allowed to loathe and hate some of the things my enemies do… Consequently, Christianity does not want us to reduce by one atom the hatred we feel for cruelty and treachery… Even while we kill and punish we must try to feel about the enemy as we feel about ourselves — to wish that he were not bad, to hope that he may, in this world or another be cured: in fact, to wish his good.
Such words had a special poignancy, of course, at this time.
The main contribution one can make as a student to one’s country in peace or wartime is to study hard and effectively, not to daydream about what else one might be doing. But we all also tried to do something more directly. For my part, I would serve one or two evenings a week at the Forces canteen in Carfax. British soldiers and American airmen from the nearby bases at Upper Heyford were among our main customers. It was hot, sticky and very hard on the feet. But the work was also good fun, with plenty of company and wisecracking humour.
Reports of the D-day landings in July 1944, though, brought both apprehension and anxiety. The deadly struggle on those exposed beaches, carried on by so many of about my own age, made us deeply uneasy. For perhaps the only time I wondered whether I was right to be at Oxford.
In fact we were now within a year of the end of the war in Europe. There were still the battle of the Bulge and the tragedy of Arnhem to come. But slowly the emphasis came to be on preparing for peace. And among the peacetime activities which began to take an increasing amount of my time was politics.
