People believe they have long since outgrown the illusions and superstitions of the past, yet in some respects they are entirely given up to illusion. There is a growing tendency to live in illusion concerning some important and essential aspects of the great scheme of things, and this to such an extent that these illusions become powers that rule the world, nations and, indeed, the whole earth. It is important to realize this, for illusory ideas are a major element in the chaos in which we find ourselves today; in fact, they make it a chaos.
