I speak of a complex and contradictory architecture based on the richness and ambiguity of modern experience, including that experience which is inherent in art... I welcome the problems and exploit the uncertainties... I like elements which are hybrid rather than "pure", compromising rather than "clean", ...accommodating rather than excluding... I am for messy vitality over obvious unity... I prefer "both-and" to "either-or", black and white, and sometimes gray, to black or white... An architecture of complexity and contradiction must embody the difficult unity of inclusion rather than the easy unity of exclusion.
