Idleness, then, is so far from being the root of all evil that it is rather the true good. Boredom is the root of evil; it is that which must be held off.
Since boredom advances and boredom is the root of all evil, no wonder, then, that the world goes backwards, that evil spreads. This can be traced back to the very beginning of the world. The gods were bored; therefore they created human beings. Adam was bored because he was alone; therefore Eve was created. Since that moment, boredom entered the world and grew in quantity in exact proportion to the growth of population. Adam was bored alone; then Adam and Eve were bored en famille. After that, the population of the world increased and the nations were bored en masse. To amuse themselves, they hit upon the notion of building a tower so high that it would reach the sky. This notion is just as boring as the tower was high and is a terrible demonstration of how boredom had gained the upper hand. Then they were dispersed around the world, just as people now travel abroad, but they continued to be bored. And what consequences this boredom had: humankind stood tall and fell far, first through Eve, then from the Babylonian tower.
