Actually there can be no constructive thinking respecting history apart from culture, Since history is always the history of a people, it is reasonable that the historical event-a political movement, a style of art, a technological innovation, a scientific discovery -should be prepared by the ambience of culture. It is only possible to speak, therefore, with generality of the contours of culture, but not to fix them with finality, for culture is the latency of history, the actuality given and the possibilities implicit but unrealized.
