Commenting on the Socratic Club at Oxford, C.S. Lewis stated, "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.”
