For many observers, today's world seems indecipherable. The Earth is in such jeopardy that some scientists speak of a new accelerated geological era. The resurgence of barbarism and terrorism in the name of religion is seen as a historical regression.At the same time, waves of technological innovations are constantly surging, particularly in the fields of energy and information -- sources of economic, ecological and social transformations. These advances point to an accelerated evolution of the human being.Never has the present been subjected to such a tectonic shock between its future and its past, the consequences of which seem difficult to foresee and can sometimes be distressing.Between na ve belief in the unlimited benefits of technology and resignation to the cycle of calamities, there is room to build a global governance aiming at organising a geopolitical order to derive the best of the human experience. This book opens us to a better understanding of our times.
