“Lucy,” came the call again, neither her father’s voice nor Peter’s. She sat up, trembling with excitement but not with fear. The moon was so bright that the whole forest landscape around her was almost as clear as day, though it looked wilder. Behind her was the fir wood; away to her right the jagged cliff-tops on the far side of the gorge; straight ahead, open grass to where a glade of trees began about a bow-shot away. Lucy looked very hard at the trees of that glade. “Why, I do believe they’re moving,” she said to herself. “They’re walking about.” She got up, her heart beating wildly, and walked toward them. There was certainly a noise in the glade, a noise such as trees make in a high wind, though there was no wind tonight. Yet it was not exactly an ordinary tree-noise either. Lucy felt there was a tune in it, but she could not catch the tune any more than she had been able to catch the words when the trees had so nearly talked to her the night before. But there was, at least, a lilt; she felt her own feet wanting to dance as she got nearer. And now there was no doubt that the trees were really moving—moving in and out through one another as if in a complicated country dance. (“And I suppose,” thought Lucy, “when trees dance, it must be a very, very country dance indeed.”) She was almost among them now. The first tree she looked at seemed at first glance to be not a tree at all but a huge man with a shaggy beard and great bushes of hair. She was not frightened: she had seen such things before. But when she looked again he was only a tree, though he was still moving. You couldn’t see whether he had feet or roots, of course, because when trees move they don’t walk on the surface of the earth; they wade in it as we do in water. The same thing happened with every tree she looked at. At one moment they seemed to be the friendly, lovely giant and giantess forms which the tree-people put on when some good magic has called them into full life: next moment they all looked like trees again. But when they looked like trees, it was like strangely human trees, and when they looked like people, it was like strangely branchy and leafy people—and all the time that strange lilting, rustling, cool, merry noise. “They are almost awake, not quite,” said Lucy. She knew she herself was wide awake, wider than anyone usually is.”
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.
