"<p></p> <p>The real cause of most human misfortune, misery, hopeless, shameful and unfortunate human situations is most often not the evil of people, but simply stupidity. That certain "slothfulness for good" of which the Bible speaks. A murderer is a rather rare human phenomenon. Murder requires strength, personality, imagination, great passions. Murderers can be defended against. The more common one, the one against whom there is no defence, the one who breeds human misery and tragedy by the millions, is the pious and tuneful man who turns his head when he sees something vile or unjust, who does not pick up the phone, even if he could help by this warning, he walks carefully round human misery and passes it by without a word, when he could, without any great sacrifice or effort, restore a man's zest for life or help a wretch. The man who goes to war with the world for his own tyranny is not so dangerous as the polite, sly and prudent mediocrity, the humming mediocrity, the cowardly and lazy selfishness. That is the cardinal sin. This is the kind of man who makes the world what it is, and to him we owe it if, in the light of this experience, we bid farewell to the human world at the hour of our death without any particular regret.</p>"
