Aims to rethink Europe under the sign of openness and hospitality, starting from the Mediterranean-the sea that is so important for the history of the entire West-a sea of differences with a deep unitary root conceived as a paradigm for rethinking new and original forms of social and political coexistence.The essays collected here outline a geophilosophy of the Mediterranean-a sea of great importance in the history of Europe and the wider West. Conceived from a geophilosophical perspective, the Mediterranean is a sea surrounded by lands-that is, a "pluriverse" of different cultures and religions, which have often become entangled in conflicts. Nevertheless, they have also demonstrated a remarkable capacity for coexistence, as exemplified by multilingual, multiethnic, and multireligious Sicily during the reign of Roger II of Hauteville. Throughout its millennia-long history, the Mediterranean has consistently displayed a profoundly unified configuration despite its inherent diversity. Its distinctive blend of singularity and plurality can serve as a paradigm for rethinking new forms of social and political coexistence, not only for Europe, which draws its origin from this sea, but also for a new global order.
