This chapter explores the concept of “multiple risks” based on the thinking of Werner Heisenberg, who, as early as 1942, perceived a profound crisis in the foundations of Western civilization. It highlights the collapse of old certainties, disrupted by the growing complexity of reality and the interconnection of different levels of reality. Heisenberg evokes a rupture comparable to that at the beginning of our era, where the link with the past becomes fragile, threatening the continuity of values. The author emphasizes the inability to predict the future and the need to accept the coexistence of multiple logics and realities. Faced with crisis, human thought oscillates between rigidity and imagination, seeking to remain anchored in reality. The current crises are expressed at various levels: individual, national, geopolitical, and civilizational. The fragmentation of the very notion of “world” is highlighted, with each level obeying its own rules of operation. Finally, the author invites us not to limit ourselves to a single reading of the past in order to understand the present, but to navigate between these different levels in order to comprehend the global crisis.
