The heart of his essay is that this urban model of proximity cannot be resolved in shortening distances with services, but must coincide with that of care. What does that mean exactly?
Care, first of all, is a series of practices, it is the responsibility of supporting, repairing and maintaining life in wider ecosystem of which we are part. Therefore, it is something that cannot depend on the single, but must be generated collectively by multiple interdependent entities. There is a beautiful African proverb that says that it takes an entire village to educate a child. It is clear that our cities are not and will no longer be a village, but what the city of proximity helps to recover is the widespread collective strength. By cure I do not mean the action of someone towards someone else or something at a specific moment: we have all been children, as in the African proverb, we will all grow old, many of us will have children and we will all have diseases.
We all have and will need care. When we all act with empathy towards others, we put in place caring relationships. Children once played in the streets independently, without anyone controlling them, when in reality there was a spontaneous network (shopkeepers, pensioners, people at the window) that did it. The arrival of cars, progress, has canceled all of this, but it is also true that even where there are no cars, children no longer play alone on the street, because that system of relationships and trust that allowed it has failed. Proximity and care means reactivating that trust, and cannot be achieved simply by closing the roads to cars.
