Robert Stern breaks down the constellation of postmodern movements in 1970s architecture, explaining what will (and did) constitute Post-Modernism, leaving Eisenman's Post-Functionalism and White architecture waiting in the wings for Post-Modernism to die.
Peter Eisenman defines the real nature of the modern sensibility and of the architectural object in a world no longer ruled by the form-function axis. What remains in this post-functionalist world is an architectural object concerned with itself, its own process and its own history--a theoretical object.
"11 Weeks of Michael Hays" : John Hejduk : Wall House
John Hejduk uses his 1972 project (kind of) to explain the development and rigor of an architectural vocabulary in an effort to dissolve the distinction between Form and Content by replacing them with critical architecture.
"11 Weeks of Michael Hays" : Colin Rowe : "Introduction" to Five Architects, 1972.
Colin Rowe, like others, is fighting to restore architecture's autonomy from ideology and 'content,' making a way for architecture to proceed, after modernism, as a formal art.
