Tory Christian though he was, I think C. S. Lewis would have approved of Critical Race Theory, at least the way it understands human limitation and tries to get people to understand that they see the world a certain way, which blinds them to other ways.
Lewis was a cold-blooded realist in the way he understood man, as I explained in C. S. Lewis Doesn’t Recommend Christianity and in C S Lewis Shows Us How to Talk About Other People’s Sins. He stressed how little we see and how often we see what's not there, because we like our fantasies better. They do more for us. We need aids in seeing the world rightly.
