"...it is in the urban environment--in a world that man himself has made--that mankind first achieved an intellectual life and acquired those characteristics which most distinguish him from the lower animals and from primitive man. For the city and the urban environment represent man's most consistent, and on the whole, his most successful attempt to remake the world he lives in more to his heart's desire. But if the city is the world which man created, it is the world in which he is henceforth condemned to live. Thus, indirectly, and without any clear sense of the nature of his task, in making the city he has remade himself."
