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.

I don't see a wall "I don't know, really. It's just a sense I have that ever since about the middle of September, we haven't really been communicating. It's like there's a wall between us and you're refusing to acknowledge it's there." "I don't see a wall." "That's what I mean. You're refusing to admit there was ever anything other than this." "Than what?" Alain de Botton, On Love It doesn't look like anything to me
