The nation-state is the focal point of modern society, but globalisation undermines this. Technological, cultural, economic and political changes are creating a ‘global village’. Postmodernists argue that these changes indicate the arrival of a postmodern society, which leaves society as unstable, fragmented and media-saturated. They reject meta-narratives such as Marxism because there is no objective criteria to prove whether a theory is true. However, Giddens believe such changes are the result of a late-modern society, not a postmodern society.
