Bridges as walls The biographer of Robert Moses, Robert A. Caro, refers to the bridges and underpasses of the famed New York State parkways. These bridges and underpasses are quite low, intentionally specified by Moses to allow only private cars to pass. All those who traveled by bus because they were poor or black or both were barred from the use and enjoyment of the parkland and its "public amenities" by the technical design of the bridges. Even at the time of Robert Moses, a political statement of the form "We don't want them blacks in our parks" would have been unacceptable in New York State. But a technological expression of the same prejudice appeared to be all right. Of course, to the public the intent of the design became evident only after it was executed, and then the bridges were there. Ursula M.

The Metabolist philosophy Tange put Tsukiji as the centre of his plan, which now seems grandiose and delusional. His design for the Dentsu building had much in common with the Metabolist philosophy of the 1960s, which maintained that buildings needed to continually evolve in a flexible way. ...With [the Nakagin Capture Tower], Kurokawa's Metabolist philosophy was fully realized. After it was completed, however, it became almost impossible to switch over the capsules - indeed, since its completion, not one of the capsules has been moved. As a result, the Metabolist movement has been forgotten. Yet its core principles, which sought to draw architectural lessons from living organisms, has much inspiration to offer society today.
