This book intertwines memories and testimonies, lived experience of cities and a critical analysis of what they have become since they stopped being islands unto themselves where, not so long ago, flâneurs might feel perfectly at home. We must take stock of what has remained open and evaluate the likelihood of conceiving a city that, without nostalgia, goes out to meet halfway those who would lend it life, rather than depending on the instincts of those whose only goal is to control it.
