Quotes about Screwtape Letters

Let us beware of the mistakes that C. S. Lewis described in Screwtape Letters. He says, "There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence, the other is to believe and to feel an unhealthy interest in them! They themselves are equally pleased by both errors, and they hail a materialist or a magician with the same delight."
