sculpture
They wanted a monument
One of the responsibilities for an architect is to provide a space that is usable and enhances the possibilities for what you do. But mostly, museums are just the opposite; they're horrible spaces, anti-art, they can't be used. They can't function, they overwhelm it. So in a way, they become objects in themselves many times, almost sculptures, and they get a lot of aggrandizement out of it...In terms of Bilbao, the one difference there is that they did not really want a museum, they wanted a monument. They wanted a thing that would bring people to the Bilbao.
Artifice, blindness, and suicide
The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really doesn't exist. This is suicide.
