Visionary architect Paolo Soleri challenges us to think of cities as biological entities with his concept of the arcology—a massive, self-sustaining, urban “organism of a thousand minds” designed to exist in harmony with nature. He proposes that the purpose of life is aesthetogenesis: the universe progressively complexifying itself into compassionate, beautiful structures. Soleri showcases 30 potential arcologies through incredibly detailed diagrams, explaining how each integrates itself economically and ecologically into the world and fulfills his aesthetogenic criteria. The scope of his vision ranges from cities designed to span canyons or float on the oceans to cube-shaped metropolises suspended on pillars, and even a space habitat. While comprehensive, Soleri's focus lies primarily on realizing arcologies that meet humanity's moral imperative for sustainable urban living.
