" The Thames that goes north, south, east, and west, to finally go east, that seeps to one side and the other as it moves forward, that goes slow as it goes fast, that evaporates into the sky whilst meandering to the sea, is more about motion than about beginnings. If it has a beginning, it is located in a dark inaccessible place. Better study where it goes than where it comes from. "
