What is a beautiful building? To be modern is to experience this as an awkward and possibly unanswerable question, the very notion of beauty having come to seem like a concept doomed to ignite unfruitful and childish argument. How can anyone claim to know what is attractive? How can anyone adjudicate between the competing claims of different styles or defend a particular choice in the face of the contradictory tastes of others? The creation of beauty, once viewed as the central task of the architect, has quietly evaporated from serious professional discussion and retreated to a confused private imperative.
