This text documents a seminal 1982 debate at Harvard University between architects Christopher Alexander and Peter Eisenman, highlighting their fundamentally conflicting philosophies regarding the future of architecture. Alexander advocates for a New Paradigm rooted in objective harmony, human feeling, and wholeness, arguing that buildings should provide comfort and reflect a deep connection between humanity and the universe. Conversely, Eisenman presents a deconstructivist view, asserting that modern architecture should reflect alienation, disharmony, and intellectual complexity to match a fragmented modern cosmology. The exchange transitions from theoretical discussions on post-structuralism and science to heated disagreements over specific architectural elements like pitched roofs and cathedrals. Editors' commentaries further analyze the historical impact of the encounter, noting that while Eisenman's transgressive style gained professional dominance, Alexander’s focus on the nature of order remains scientifically significant. Ultimately, the source illustrates the enduring tension between human-centric design and abstract intellectualism in the built environment.
