A new social question? A few questions on the territorialisation of policies - This paper addresses two fields of observation that are quite different from each other. In the first, the spatial metaphor of a network emphasises the horizontal dimension: according to Castells, spatialisation is in some ways the basic constituent of the network society. Spatialisation highlights those features which are expressed in extreme images of segregation, which include the multiplication of the ‘wall’ prototype. The second field of observation consists of territorialised policies and the territories that they form. Although very far apart, what the fields have in common is the reference to space and in particular to space as a device for government. Put briefly, the territorialisation of policies must be investigated with account taken of the spatialisation and of territory as a technology of power which accompanies the formation of the network society.
