The article aims at determining the critical conscience of our time in clarifying our present postmodern situation. The A. first studies a range of centres of interest in the works of important postmodernist thinkers (Wolfgang Welsch, Jean-François Lyotard, Richard Rorty…) before tackling Jürgen Habermas' position in the debate. He then outlines a rough estimate of this postmodernist panorama. A «triangle of the postmodernist critical conscience» shows the many similarities and discrepencies between the various theoreticians under consideration. A critical discussion, conducted with these authors and about them, leads to the paradigm of the «open narrative» as an available mode of the critical contemporary conscience, a model which helps us at recontextualising the Christian narrative in our postmodern situation.
