Liaisons is an international editorial collective that gathers experiences from struggles around the world. For our second book, Horizons, we asked comrades whether it's still possible to envision revolution today, and to what extent classical notions of revolution might need to be rethought. Our inquiry received a variety of responses: while some emphasize the absence of horizons or search for lessons among experiments and failures of the past, others suggest revolution might be re-conceived as the gradual growth of a revolutionary force and the accumulation of partial victories. With ten texts from France, Germany, Italy, Japan, Mexico, Sudan, and the US, Horizons is a planetary attempt to rethink and renew the revolutionary tradition in the twenty-first century.
