Although I had never been unhappy and in fact enjoyed my public school, the transition from public school to university was altogether delightful. There is a psychological uplift about being treated by adults as an equal instead of an inferior, as a rational being instead of a child, which no-one can understand who has not experienced it. I felt for the first time like a mature person, who could be persuaded by argument but not ordered about like a domestic pet. As my main interests at Eton had been history and philosophy, I decided to take my degree in what was then the new school of Modern Greats. This included the trinity of history, philosophy and economics, and covered much the same ground as is covered now by PPE. My tutor was Humphrey Sumner, who took what was thought to be the brightest of the new intake of undergraduates. No-one could have given a stronger visual impression of dedication to the true and the beautiful than Humphrey Sumner. His glowing eyes and parchment complexion suggested a reincarnation of Savonarola. To complete the picture he wore a flowing black cloak and a broad brimmed black hat. When you went in for a tutorial he was puffing his pipe and working indefatigably on an obscure period of Russian history. I saw him once again after I left Oxford. He descended on me one afternoon at Magdalene, Cambridge, and asked to be taken around the College and the Pepys Library. I did so with trepidation as I knew he would expect the expertise of a professional guide. I lost touch with him before he became Warden of All Souls, the crown of a great academic career.
