In the third book in the Critical Spatial Practice series, Beatriz Colomina traces the history of the modern architecture manifesto, with particular focus on Mies van der Rohe, and the play between the written and built work. This essay propels the manifesto form into the future, into an age where electronic media are the primary sites of debate, suggesting that new forms of manifesto are surely emerging along with new kinds of authorship, statement, exhibition, and debate.
