“You can be good for the mere sake of goodness; you cannot be bad for the mere sake of badness. You can do a kind action when you are not feeling kind and when it gives you no pleasure, simply because kindness is right; but no one ever did a cruel action simply because cruelty is wrong - only because cruelty is pleasant or useful to him, In other words, badness cannot succeed even in being bad in the same way in which goodness is good. Goodness is, so to speak, itself: badness is only spoiled goodness. And there must be something good first before it can be spoiled.”

British author, literary scholar, and Anglican lay theologian

C. S. Lewis was a British author, literary scholar, and Anglican lay theologian. He held posts in English literature at Magdalen College, Oxford, and later at Magdalene College, Cambridge. He is best known for The Chronicles of Narnia. Lewis also wrote The Screwtape Letters and the Space Trilogy, along with Christian apologetic works such as Mere Christianity, Miracles, and The Problem of Pain. His writing ranges from imaginative fiction to religious argument, and much of it reflects his interest in Christian belief and moral questions.
