Michael Ward of Oxford University offers a perspective on “C. S. Lewis and the Art of Disagreement.” It’s well worth reading.

The fact that Lewis could approve of atheists like Ryle, as well as enjoy the company of liberals like Watson and socialists like Lawlor, reinforces Brewer’s point that Lewis would not allow disagreement to become personal. He could always distinguish the man from the man’s opinion, and he knew the difference between an argument and a quarrel. He would not allow himself to be betrayed into aggression, but would, where necessary, draw rein on a dispute with a wry smile and an agreement to disagree. – See more at: https://home.isi.org/cs-lewis-and-art-disagreement#sthash.Atgyg22T.dpuf
