The Thin Artillery of the Rationalist

Looking back in 1935 to his long friendship with Greeves, Lewis summed up their relationship and what he owed to the friend who always remained steadfast to the Christian faith however much he bombarded him with the 'thin artillery' of the rationalist. 'He remains victor in that debate. It is I who have come round. The thing is symbolical of much in our joint history. He was not a clever boy, he was even a dull boy; I was a scholar. He had no 'ideas.' I bubbled over with them. It might seem that I had much to give him and that he had nothing to give me. But this is not the truth. I could give concepts, logic, facts, arguments, but he had feelings to offer, feelings which most mysteriously- for he was always very inarticulate- he taught me to share. Hence, in our commerce, I dealt in superficies, but he in solids. I learned charity from him but failed, for all my efforts, to teach him arrogance in return.
