With the dawn of the modern age, the conquest of the third dimensionthe aerial domainset in motion a spatial revolution that irrevocably transformed humanitys relationship with the city, with territory, and with the planet itself. The view from above introduced an unprecedented form of spatial knowledge, one from the outset charged with profound practical implications: the command of space, large-scale planning, control and surveillance, and aerial warfare. At the same time, aerialor aero-spatialvision gave rise to fundamental ethical and political experiences, including the emergence of an early global consciousness and the first stirrings of ecological awareness. Through a historical and philosophical lens, this book investigates the impact of the aerial revolution on both fronts, tracing the continuities and ruptures that have shaped humanitys gradual conquest of the skies.
