Rationality is in crisis. It does not recognize the content that has been given to it since the 17th century. Conceived as a model of life, of discipline, of objectivity, of honesty, of humanism, of truth and of progress, it has strangely shied away from this model since the very day Descartes gave it birth. Rationality is a tool of double talk, a pretext for a moral truth that is never fulfilled, because it does not believe in itself. It is a pawn in the hands of a few enlightened people who use it to take over all the spaces of the world in the name of peace, development and democracy. But rationality crosses a space without being crossed by it. It never leaves its mark. The only memory that we always have of it is fabrication, arrogance, egoism and misery. The author shows how these paradoxes, of which only rationality has the secret, are represented and deconstructed by postmodern French novelists in order to restore truth, humility and the entanglement of world cultures.
