C. S. Lewis
Lewis was commissioned to write the volume "English Literature in the Sixteenth Century (Excluding Drama)" for the Oxford History of English Literature, His book "A Preface to "Paradise Lost"" is still cited as a criticism of that work. His last academic work, "The Discarded Image: An Introduction to Medieval and Renaissance Literature" (1964), is a summary of the medieval world view, a reference to the "discarded image" of the cosmos.
Lewis was a prolific writer, and his circle of literary friends became an informal discussion society known as the "Inklings", including J. R. R. Tolkien, Nevill Coghill, Lord David Cecil, Charles Williams, Owen Barfield, and his brother Warren Lewis. Glyer points to December 1929 as the Inklings' beginning date. Lewis's friendship with Coghill and Tolkien grew during their time as members of the Kolbítar, an Old Norse reading group that Tolkien founded and which ended around the time of the inception of the Inklings. At Oxford, he was the tutor of poet John Betjeman, critic Kenneth Tynan, mystic Bede Griffiths, novelist Roger Lancelyn Green and Sufi scholar Martin Lings, among many other undergraduates. Curiously, the religious and conservative Betjeman detested Lewis, whereas the anti-establishment Tynan retained a lifelong admiration for him.
Owen Barfield
Barfield and C. S. Lewis met in 1919 as students at Oxford University and were close friends for 44 years. "It is no exaggeration to say that his friendship with Barfield was one of the most important in his [Lewis's] life…” The relationship was reciprocated. Almost a year after Lewis's death, Barfield spoke of his friendship in a talk in the USA: "Now, whatever he was, and as you know, he was a great many things, CS Lewis was for me, first and foremost, the absolutely unforgettable friend, the friend with whom I was in close touch for over 40 years, the friend you might come to regard hardly as another human being, but almost as a part of the furniture of my existence.” When they met, Lewis was an atheist who told Barfield, "I don’t accept God!" Barfield was influential in converting Lewis. Lewis developed the concept of two kinds of friends, a first friend with whom you feel at home and agree and a second friend who brings to you a different point of view. He found Barfield's contribution in this way particularly helpful despite, or because of, the fact that “during the 1920s, the two were to engage in a long dispute over Barfield's (and their mutual friend, A.C. Harwood's) connection to anthroposophy and the kind of knowledge that imagination can give us… which they affectionately called 'The Great War'. Through their conversations, Lewis gave up materialist realism – the idea that our sensible world is self-explanatory and is all that there is – and moved closer to what he had always disparagingly referred to as “supernaturalism.” These conversations influenced Lewis towards writing his Narnia series. As well as being friend and teacher to Lewis, Barfield was (professionally) his legal adviser and trustee.
