The Fundamentals for the Twenty-First Century: Examining the Crucial Issues of the Christian Faith Book

This is a collection of essays and letters by C.S. Lewis that mostly aren't available elsewhere. Probably my favorite of all the essays is "Man or Rabbit?", which is a word-picture of conversion. ("All the rabbit in us is to disappear -- the worried, conscientious, ethical rabbit as well as the cowardly and sensual rabbit.")
Some of the essays are less interesting to me, and some of them I don't find interesting at all. But Lewisian gems are sprinkled everywhere, and I like that his curmudgeonly side comes out.
Some samples:

"The moment a man seriously accepts a deity his interest in 'religion' is at an end. He's got something else to think about."

"It may be better to live under robber barons than under omnipotent moral busybodies."

"If it were my business to have a 'view' on this, I should say that I much approve of merry-making. But what I approve of much more is everybody minding his own business."

"Can it really be my duty to buy and receive masses of junk every winter just to help the shopkeepers?"

"Didn't they know that, Bomb or no Bomb, all men die (many in horrible ways)? There's no good moping and sulking about it."

"A right to happiness doesn't, for me, make much more sense than a right to be six feet tall."

"Most political sermons teach the congregation nothing except what newspapers are taken at the Rectory."

"I have never helped to organize youth, and while I was young myself I successfully avoided being organized."

Adding this from a delightfully curmudgeonly essay called, "Delinquents in the snow":

At my front door they are, once every year, the voices of the local choir, on the forty-five other annual occasions they are those of boys or children who have not even tried to learn to sing, or to memorize the words of the piece they are murdering. The instruments they play with real conviction are the door-bell and the knocker; and money is what they are after.
