world in flux, a world that has become both increasingly interconnected and prone to severe and persistent crises. We are living in the interregnum between what is no longer and what is not yet. None of the political movements that helped undermine the old world are ready to inherit it, and there is no new ideology, no consistent vision, promising to give shape to new institutions for the new world. It is like the Babylon referred to by Borges, the country of randomness and uncertainty in which 'no decision is final; all branch into others'. Out of the world that had promised us modernity, what Jean Paul Sartre had summarized with sublime formula 'le choix que je suis' ('the choice that I am'), we inhabit that flattened, mobile and dematerialized space, where as never before the principle of the heterogenesis of purposes is sovereign. This is Babel.
