Everybody's got a poster on his or her wall, real or imaginary. Bureaucrats have presidents, governors, and/or other frighteners (like J. Edgar Hoover). Teenagers often have non-authority figures, as I had James Dean, or Marlon Brando with motorcycle jacket, or Elvis. My daughters had Kiss and Sid Vicious. It's a means of shorthand which does away with a lot of preliminary discussion. This is a more-or-less legitimate use of the argumentation technique, "Appeal to Authority." I would rotate the personages on my imaginary office wall today. These people would certainly be in the rotation: Murray Rothbard, Robert Higgs, Mark Twain, William of Ockham, John Donne, Frederic Bastiat, and Thomas Jefferson. Who's on your wall?
