Postmodernism theory is one of those attempts: the effort to take the temperature of the age without instruments and in a situation in which we are not even sure there is so coherent a thing as an "age,"or zeitgeist or "system" or "current situation"any longer. Postmodernism theory is then dialectical at least insofar as it has the wit to seize on that very uncertainty as its first clue and to hold to its Ariadne's thread on its way through what may not turn out to be a labyrinth at all, but a gulag or perhaps a shopping mall.

The moderns were interested in what was likely to come of such changes and their general tendency: they thought about the thing itself, substantively, in utopian or essential fashion.

Theories of the postmodern - whether celebratory or couched in the language of moral revulsion and denunciation - bear a strong family resemblance to all those more ambitious sociological generalizations which, at much the same time, bring us the news of the arrival and inauguration of a whole new type of society, most famously baptized "postindustrial society"(Daniel Bell) but often also designated consumer society, media society, information society, electronic society, or high tech and the like. Such theories have the obvious ideological mission of demonstrating, to their own relief, that the new social formation in question no longer obeys the laws of classical capitalism, namely, the primacy of industrial production and the omnipresence of class struggle.

Postmodernism is what you have when the modernization process is complete and nature is gone for good. It is a more fully human world than the older one, but one in which "culture" has become a veritable "second nature."
