Abstract: | To explain both origin and outcome of disasters ( natural , technical , and war-borne ), as well as social action during disasters proper, a macrosociological model of internal causation is introduced ( PERDUE ). It consists of six stages of possible, and of most likely paths of social change between these six ( Peace is founded , Everyday routine , Rising class struggle , Disasters strike , Unconditional surrender of collective defence , and Evaporation of common values ). The stages are developed by making use of three dimensions of social change ( rapidity , radicality , and rituality ), and described. |
