The globalised city obliges us to reconsider the city itself in order for us to be capable to propose a new paradigm for its future. The technological facts have penetrated a ‘world in the World’. In other words, all of a sudden, the techno-scientific instruments arises as a ‘virtual world’ on the Web, provoking a double decomposition of the notion of space, such that the individual is no longer only represented in the actual space of the territory – local – but also in the interactive space of communication – global.
The basic thesis of this work is, on the one hand, the form of a city emerges from the choice of its physical site; and on the other hand, it modifies itself through geo-historical actualisation. The theory of urban form proposes a global theory of the engendering of forms and their relationships to spatial positions.
Does physical space, especially what is perceived visually, has the same structure as the social, territorial space, or that of our abstractions? How are the fabricated spaces (theatrical, fictional, pictorial, sculptural, architectural) the expression of our spatial imaginary? What is the contribution of a cognitive semiotics to the understanding of the spatial meaning and its visual hypostases? How have the new modalities of seeing led to the evolution of semiotic functions?
