In the wake of rapid globalization, many enthusiastically declared cosmopolitanism to be no longer just a philosophical ideal, but a real, existing fact. Across the world, they argued, people were increasingly considering themselves global citizens. Meanwhile, the global ecological crisis worsened, fascism returned, repression of disenfranchised groups on a global scale persisted, and the "refugee crisis" inundated the mediascape. What happened to the cosmopolitan promise, and who betrayed it? minor cosmopolitan challenges the underlying premises of major cosmopolitanism without letting go of the unfulfilled emancipatory potential of the concept at large. It rethinks cosmopolitanisms in the plural, and it traces multiple origins and trajectories of cosmopolitan thought across the globe. Assembling theoretical, artistic, and essayistic contributions in textual or visual formats, minor cosmopolitan seeks to discuss how to live at once with our difference and shared struggle and asks who sustains the world's flourishing.
