Maybe the CIA will now open an Art Historical and Symbolical Branch to examine the works of artists for evidence of dangerous thoughts. GK Chesterton got it right back in 1908: "The work of the philosophical policeman," replied the man in blue, "is at once bolder and more subtle than that of the ordinary detective. The ordinary detective goes to pot-houses to arrest thieves; we go to artistic tea-parties to detect pessimists. The ordinary detective discovers from a ledger or a diary that a crime has been committed. We discover from a book of sonnets that a crime will be committed. We have to trace the origin of those dreadful thoughts that drive men on at last to intellectual fanaticism and intellectual crime. We were only just in time to prevent the assassination at Hartlepool, and that was entirely due to the fact that our Mr. Wilks (a smart young fellow) thoroughly understood a triolet." (From The Man who was Thursday, chapter 4, copied from Christian Classics Ethereal Library at http://biblestudy.churches.net/CCEL/C/CHESTERT/THURSDAY/THURSDAY.TXT) The website at http://huizen.dds.nl/~wandm/paint2.html claims that the drawings were made between 1983 and 1989. There are signatures and dates visible on the pictures. Even the Koontz article claims that they have existed at least since 1998. If this is true they can hardly have been a signal to the hijackers to go into action. At the most, evidence of the artist's state of mind. Ken Brown
