Philosopher and politician Roberto Mangabeira Unger recently attempted to revise classical social theory by exploring how things fit together, rather than to provide an all encompassing single explanation of a universal reality. He begins by recognizing the key insight of classical social theory of society as an artifact, and then by discarding the law-like characteristics forcibly attached to it. Unger argues that classical social theory was born proclaiming that society is made and imagined, and not the expression of an underlying natural order, but at the same time its capacity was checked by the equally prevalent ambition to create law-like explanations of history and social development. The human sciences that developed claimed to identify a small number of possible types of social organization that coexisted or succeeded one another through inescapable developmental tendencies or deep-seated economic organization or psychological constraints. Marxism is the star example.
