“Is it rational to believe in a bad God? Anyway, in a God so bad as all that? The Cosmic Sadist, the spiteful imbecile? I think it is, if nothing else, too anthropomorphic. When you come to think of it, it is far more anthropomorphic than picturing Him as a grave old king with a long beard. That image is a Jungian archetype. It links God with all the wise old kings in the fairy-tales, with prophets, sages, magicians. Though it is (formally) the picture of a man, it suggests something more than humanity. At the very least it gets in the idea of something older than yourself, something that knows more, something you can't fathom. It preserves mystery. Therefore room for hope. Therefore room for a dread or awe that needn't be mere fear of mischief from a spiteful potentate. But the picture I was building up last night is simply the picture of a man like S.C. - who used to sit next to me at dinner and tell me what he'd been doing to the cats that afternoon. Now a being like S.C., however magnified, couldn't invent or create or govern anything. He would set traps and try to bait them. But he'd never have thought of baits like love, or laughter, or daffodils, or a frosty sunset. He make a universe? He couldn't make a joke, or a bow, or an apology, or a friend.”
Clive Staples Lewis was born in Ireland, in Belfast on 29 November 1898. His mother was a devout Christian and made efforts to influence his beliefs. When she died in his early youth her influence waned and Lewis was subject to the musings and mutterings of his friends who were decidedly agnostic and atheistic. It would not be until later, in a moment of clear rationality that he first came to a belief in God and later became a Christian.
C. S. Lewis volunteered for the army in 1917 and was wounded in the trenches in World War I. After the war, he attended university at Oxford. Soon, he found himself on the faculty of Magdalen College where he taught Mediaeval and Renaissance English.
Throughout his academic career he wrote clearly on the topic of religion. His most famous works include the Screwtape Letters and the Chronicles of Narnia. The atmosphere at Oxford and Cambridge tended to skepticism. Lewis used this skepticism as a foil. He intelligently saw Christianity as a necessary fact that could be seen clearly in science.
"Surprised by Joy" is Lewis's autobiography chronicling his reluctant conversion from atheism to Christianity in 1931.
