““Only the modern city,” Hegel dares write, “offers the mind a field in which it can become aware of itself.” We are thus living in the period of big cities. Deliberately, the world has been amputated of all that constitutes its permanence: nature, the sea, hilltops, evening meditation. Consciousness is to be found only in the streets, because history is to be found only in the streets—this is the edict.””
