A couple of good quotes spoted on Doug Groothuis's blog:
George Orwell: "We have now sunk to a depth at which restatement of the obvious is the first duty of intelligent men."
From a letter by C.S. Lewis: "What is the point of keeping in touch with the contemporary scene? Why should one read authors one doesn't like because they happen to be alive at the same time as oneself?" (6 Jan 1951)
