History, like a vast river, propels logs, vegetation, rafts, and debris; it is full of live and dead things, some destined for resurrection; it mingles many waters and holds in solution invisible substances stolen from distant soils. Anything may become part of it; that is why it can be an image of the continuity of mankind. And it is also why some of its freight turns up again in the social sciences: they were constructed out of the contents of history in the same way as houses in medieval Rome were made out of stones taken from the Coliseum.
