“In any fairly large and talkative community such as a university, there is always the danger that those who think alike should gravitate together into coteries where they will henceforth encounter opposition only in the emasculated form of rumor that the outsiders say thus and thus. The absent are easily refuted, complacent dogmatism thrives, and differences of opinion are embittered by group hostility. Each group hears not the best, but the worst, that the other groups can say. In the Socratic all this was changed. Here a man could get the case for Christianity without all the paraphernalia of pietism and the case against it without the irrelevant sansculottisme of our common anti-God weeklies. At the very least we helped to civilize one another; sometimes we ventured to hope that if our Athenian patron were allowed to be present, unseen, at our meetings he might not have found the atmosphere wholly alien.”
-C.S. Lewis, commenting on the Oxford Socratic Club in God in the Dock: Essays on Theology and Ethics
