I don’t believe the war is simply the work of politicians and capitalists. Oh no, the common man is every bit as guilty; otherwise, people and nations would have rebelled long ago! There’s a destructive urge in people, the urge to rage, murder and kill. And until all of humanity, without exception, undergoes a metamorphosis, wars will continue to be waged, and everything that has been carefully built up, cultivated and grown will be cut down and destroyed, only to start all over again!
