The debates about the organization of state-articulated modernity, which succeeded 19th-century liberal modernity and underwent a crisis in the 1970s and 1980s, were left without a conclusion. Instead of summing up the post-modernist ideas, this article argues that we are today in the midst of a third stage of modernity, which is characterized by greater evolutionary complexity and mixed articulation. This, together with the growth of other, more fluid and contingent forms of sociability, has recourse to three principles: market, hierarchy (within corporations and the state) and network. The example of contemporary procedural law is drawn upon to illustrate the discussion.
