Book excerpt: Curious about the images of the city that have been evolving in the different social sciences, we did what academics often do in such a situa 1 tion: we set up a seminar on "Images of the City in the Social Sciences." From the start, we counted on the help of specialists in other fields to pursue their interests. Of the persons who agreed to participate, all but two came from the United States, and their analyses, in the main, reflect the experience of Western countries and the United States. In our formal instructions to our collaborators, we took fi>r granted that a variety of images of the city could be found or inferred in their fields of expertise. We asked them to identify these images and their functions, to explain how and why they have changed over time, and to relate these images to the distinct intellectual traditions and techniques-analytical or otherwise-in their respective fields. The definition of image was left to the judgment of the participants.
