During his 1994 visit to Highgate Cemetery outside London, Dr. Jonathan M. Kolkey stood alongside Karl Marx's gravesite. During a very "spiritual" moment the two men shared on a blustery January day, Dr. Kolkey "told" Karl that although he (Dr. Kolkey) appreciated Marx's obvious good intentions, the German philosopher/historian was dead wrong about the causes of war and hence thoroughly deserved to have his erroneous theories buried forever.
