ENThe concept of “milieu” has an interesting history that problematizes the limits of individuality and addresses the role of the living in terms of mutual creativity with its own environment. In fact, born in the context of mechanics and biology, the term “milieu” has been gradually charged with philosophical meaning that puts at the center the question of creativity: to what extent do we create the environment and are we created by it? It is not by accident that, in the philosophy of Gilbert Simondon, who exercised the fundamental revalorization of this concept, we encounter the idea of a milieu as associated with the individual. This means that a milieu signalizes the network of potentialities that, formally speaking, does not belong to its individuality, while, at the same time, it constitutes the creative field of its subjectivity. Today, when the question of environment seems to offer a lot of pressing challenges, a better understanding of our creative interaction appears to be one of the gateways offering a new understanding that enters into worldly encounters.
