“Let us try to define this question more clearly. We will consider the following simplified scheme: on the one hand, a social practice, and on the other, the materiality in which this social practice is inscribed.
Social practice, a Brownian motion, constantly changing, subject to fluctuations, cycle, fashion, perpetual modifications, from the most common actions of everyday life to the most abstract philosophical reflections: this social practice develops inscribes itself, and exists in a materiality that also varies, although generally less rapidly. Materiality is discontinuous, it is composed of objects, of things; objects as material beings have an existence, a life span. They are born at the moment of their manufacture, they live, are worn down in yielding a service, allow themselves to be used, then expire when they become useless. We may speak of the life of an object and call it obsolescence. The obsolescence of an automobile today is 4 to 5 years, the obsolescence of a paper dress is only a few hours.
The object that interest us here are those that constitute urban space, in particular constructed space in the strict sense of the word.”

“Art production of the 20th century might have been a rarified field, but in the 21st century, cultural production has become a necessary component of organizing social action. In other words, if the world is a stage, then the players must learn the skills of theater.” (Thompson)
