Governing globalisation through law implies building the rule of law without a world State, and therefore rethinking the tool that law, traditionally identified with the State, represents in the face of the interdependencies born of globalisation and the challenges they generate Economic and financial crises, social crises, global terrorism;the humanitarian disaster of migrations, the climate crisis and, to top it all off, the coronavirus health crisis: it is time to take them seriously, as the cacophony of this poly-crisis amplifies As if citizen indignation at security abuses, the anger of the yellow vests at social inequalities, the revolt of the younger generations and the calls of scientists regarding climate change had not been enough, it took a simple virus, smaller than a butterfly’s wing, to shake the world, to the point of finally shaking the certainties of our leaders The great powers, or those merely thinking of themselves as such, proud of their new technologies and convinced of their political and/or economic power, are proving incapable of coordinating on a global scale It is as if this tiny living being had come as a messenger to challenge our globalised humanity and reveal its fragility, offering it one last chance to realise its common destiny In sum, a human commitment to better govern the galloping and unpredictable globalisation is needed
