Section One
The city is an accumulation of human civilization. Just as the American social philosopher (哲学家) Lewis Mumford put it, it is a special system which, fine and compact, has been designed to preserve the fruits of human civilization. Many Western languages have developed their versions of the term “civilization” from the same Latin (拉丁语的) word “civitas”(meaning “city” ), and it is by no means a coincidence. The city has played a significant role in the perfection of order in human society.
