Replace ideology. Toward new urban visions

How architects means today the reality has to be? From South America to China, the hyper-metropolis, is paradoxical in its inhumanity. Is the economics and financial system a degenerate form of ideology, or an implicit destiny in the construction of the city of the past, unable to accept and include or even resist the social and economic transformations of our time? Or the European city can still set an example or an alternative to global mega-cities? The uniquely instrumental ability, or, the ability of architecture to materialize the idea of a city, or more generally the idea of space, is an assumption of this argument, and yet, although we can be certain that this capacity is always expressed, by Renaissance treatises up to the heteronomous expressions as «S, M, L, XL» which urges us to take a position as architects on the contemporary city is its aesthetic reason.
