ANTHROPOLOGY AND SOCIOLOGY ORIGINALLY FOUND THEIR more immediate inspiration in an evolutionary or Jacob's Ladder vision of human societies, the idea of Progress. Social forms were seen as located along some great Chain of Being, which eventually leads to this-worldly salvation by this-worldly means. But there the resemblance ends. Sociology was rooted in a primarily historical evolutionism, in the perception, by the generation of Condorcet and Hegel, that human history is a story of cumulative change, and in the hope that the pattern of this change was the key to the meaning of life. History was to reveal the inner potential and destiny of human society. By contrast, the evolutionism which somewhat later, around the middle of the nineteenth century, gave birth to anthropology, was markedly biological, and came to be much influenced by Darwin.
