“The [Burgess Growth] model thus shows how cities change over time from a preindustrial pattern, in which there is no clear segregation of land for specific purposes...to the complex functional differentiation characterizing contemporary urban areas.” (15) This tendency toward the segregation of space, which Palen acknowledges “seems obvious to us today,” has carried over into our very homes, our very daily existence. We have rooms for each activity. We have segments of space (in the car, the train, the plane) with which we transition from segment to segment. We have places for each thing, which are likely within other things, which each have their own appropriate place. Just as we would find it distasteful to live next door to a factory, so too we are made uncomfortable by a couch in a kitchen.
