 Advances in science and interest in political governance led theorists to draw analogies between the traditional domains of science—such as heavenly bodies, chemicals, and organisms—and the newly salient domains of economies and societies. The push to develop a science of society motivates a different emphasis in social ontology, as compared to earlier theories. Whereas ancient and early modern theorists largely investigated the sources or generators of social entities, these theorists devoted more attention to analyzing social entities into their constituent parts.
