Architecture has two kinds of content: internal and external.
Internal contents are forms, programs, and technologies…the things that are designed, organized, and synthesized in the pursuit of architecture. Internal contents are, in a broad sense, what architecture is made of.External contents are cultural: environmental issues, social movements, aesthetic transformations, political evolutions, and economic shifts. Their relationship to architecture is no less immediate if more fleeting, more variable, and more volatile. External contents are what makes architecture matter.
We use architecture's internal contents to animate architecture's external contents.
