evidence: J.R.R. Tolkien, 30th August 1964: "[C.S. Lewis] …of course had some oddities and could sometimes be irritating. He was after all and remained an Irishman of Ulster. But he did nothing for effect; he was not a professional clown, but a natural one, when a clown at all. He was generous-minded, on guard against all prejudices, though a few were too deep-rooted in his native background to be observed by him."
