One of the areas of human study that is insufficiently explored is human fear and how fear has shaped the world we live in. The exploration in this book is just a beginning point and hopefully acts as an impetus for others to explore how fear may be a primary cause of the violence that exists on this planet. It is not quite as simple as it appears at first, and most people will say, of course, fear causes violence. I have found that the root reasons for fear causing violence are not to be found in economic, social, or historical development, but rather it is psychological—this is a case where the psychology of human beings is the primary determinant of the human reaction to fear that has spawned our violent world.
