The Great Illusion in its turn created certain illusions in those who read the book superficially (or who only heard about it). Because Norman Angell had proved war to be foolish, to be a bad business proposition, many believed that he had said there would be no more war in Europe. Against this misinterpretation Norman Angell at once protested with the greatest heat. He asked: "Why then do I pursue my fight against war?" Indeed, why should pacifists continue their frequently thankless and unpopular work if they believe that war will never occur any more? Rational people do not try to break down an open door.
