This first volume of letters inaugurates a keenly awaited edition of Berlin’s letters. Berlin’s life was enormously worth living, both for himself and for us; and fortunately he said a great deal to his friends on papers as well as in person. When this volume opens Berlin is eighteen, a pupil at St. Paul’s School in London. He becomes an undergraduate at Oxford, then a Fellow at All Souls, where he writes his famous biography of Karl Marx. When that is complete he moves to New College to teach philosophy, and after the outbreak of the Second World War sails to America in somewhat mysterious circumstances with Guy Burgess. He stays in the USA, working for the British Government (apart from visits home and his famous trip to the Soviet Union in 1945-6) until July 1946, when he returns to Oxford, and the volume closes.
