In combustion engines, a synchrony of sparks, or light, catalyze the processes which emerge as the travel of the car. Of course, these also emerge as the life of the owner, and the moments of the world. Little sparks, in peculiar synchrony, create explosions in gas clouds. This ignition pushes levers that turn things, which turn other things, with move wheels with incredible force. Little sparks. Now, if you saw one of these sparks, just the spark, you might not think much of it. But in the right context, and in the proper relation with other such sparks, it changes the world. And words in minds are somewhat similar. We think we know what they do. But the man who first made these little sparks happen this way had no idea what would be accomplished with them. It was impossible to predict. It still is, in fact. Words like sparks in gas move worlds.
