Imagining the city to ensure a better dwelling place for tomorrow: a challenge summarized in 25 key concepts.

How do we inhabit our cities? What of the forest trail still inheres in our boulevards and avenues? What digital footprints do we leave in our wake? Who owns the night? Is the city of tomorrow a playing field for investors? Do you have to have a soapbox to make your voice heard?
Historians, geographers, and sociologists tackle these questions head-on, taking our habits and the stakes of the 21st-century city into account. They shed light on such essential concepts as risks, mobility, nature in the city, the digital revolution, the future of historical buildings and our cultural heritage, the role of women, and social inequality.
