ABSTRACT
SINCE the physical space in which people live and work moulds their social behaviour, any radical rebuilding of a city calls into question the accustomed social pattern. The planner has to determine how far their present way of life satisfies—or ought to satisfy—the people he is to rehouse, and the people themselves are forced to revalue their traditions. They must either repudiate them, or reaffirm them by deliberate choice, perhaps in conflict with the ideal which leaders of society are seeking to impose. Slum clearance forces the pace at which society changes, and illustrates the pressures which are shaping its future.
