"I thought that I could do it on my own, by retiring to my rooms and reading theology, and I wouldn't go to the churches. . . But as I went on I saw the great merit of it. I came up against different people of quite different outlooks and different education, and then gradually my conceit just began peeling off. I realized that the hymns (which were just sixth-rate music) were, nevertheless, being sung with devotion and benefit by an old saint in elastic-side boots in the opposite pew, and then you realize that you aren't fit to clean those boots. It gets you out of your solitary conceit." (C. S. Lewis)
