C. S. Lewis is one of my favorite authors. He had a grasp of human nature that more people should read. The Narnia series is a wonderful read (even for adults) and the Screwtape Letters are a classic.
I just read in OpinionJournal’s Political Diary a great quote from CS:
Of all tyrannies, a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busy-bodies. The robber baron’s cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end, for they do so with the approval of their own conscience.
