A Voice from the Past - Lewis

(from his abysmal majesty Screwtape, on how to tempt humans)

The first and most obvious advantage is that you thus induce him to enthrone at the centre of his life a good, solid resounding  lie. I don't mean merely that his statement is false in fact, that he is no more equal to everyone he meets in kindness, honesty, and good sense than in height or waist-measurement. I mean that he does not believe it himself. No man who says I'm as good as you believes it. He would not say it if he did.

C. S. Lewis, 1898-1963, The Screwtape Letters, Screwtape Proposes a Toast (Harper Collins Publishers, 1996, p.198).

Is there a distorted view of equality? How do we avoid it and keep a right view of equality?
