Nature’s time, thought of as linear, was more or less encompassed by the formula of evolution: the passage from inanimate matter to the first vertebrates, to fish, birds, animals, and at last to man, was progressive. As the natural sciences developed, the line was extended even further to the history of human societies. Here, too, there was to be constant progress, but until Marx there were no guarantees beyond rather vague faith.
