Somewhere every culture has an imaginary zone for what it excludes, and it is this zone that we must try to remember today.1
For something to be excluded, two parts are necessary: something inside,
some defined entity, and something outside. In our world of architectural ideology there is such an inside: the body of texts and rules developed in the Renaissance that, as a reading of the classics, established the foundations for Western
architecture, which I call the ‘system of architecture.’ This inside has been transformed throughout history, at some times more profoundly than at others, and even through the apparent breaks of the first decades of this century it has remained at the very base of Western architectural thought.
