Uses of the term

One "project" of modernity is said by Jürgen Habermas to have been the fostering of progress by incorporating principles of rationality and hierarchy into public and artistic life. (See also post-industrial, Information Age) Lyotard understood modernity as a cultural condition characterized by constant change in the pursuit of progress. Postmodernity then represents the culmination of this process where constant change has become the status quo and the notion of progress obsolete. Following Ludwig Wittgenstein 's critique of the possibility of absolute and total knowledge, Lyotard further argued that the various metanarratives of progress such as positivist science, Marxism, and structuralism were defunct as methods of achieving progress.
