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.

Repair Within the larger language, it is impossible for any act not to help repair the larger whole. It is impossible for any act of building to remain an isolated act: it always becomes a portion of the flux of acts which is helping to maintain the whole. Even the laying of a brick, to mend a wall, will not only be used to mend that wall, but will be used to help repair the seat, the terrace, or the fireplace which that wall helps to form.
