Change (1950) and Terror and Progress USSR (1954), Moore had himself utilized functionalist modes of analysis in suggesting that the functional requirements associated with the necessity to industrialize had placed a limit on attempts to realize a socialist society In Social Origins of Dictatorship and Democracy, however, rather than working with the idea of a single set of functional requirements for modernization, Moore's argument is that three distinctive historical routes to the modern world can be identified:
Not all Moore's conclusions about these three routes have found universal acceptance (see Smith, 1983). Rather, it is the subtlety of his sifting of historical data while addressing general questions, which has impressed many sociologists and which has done much to stimulate the post-functionalist flowering of historical sociology evident in recent years. Barrington Moore's own subsequent work has failed to reach the heights achieved in Social Origins. It is of interest, however, that in The Causes of Human Misery (1978), an exercise in seeking conclusions on moral questions, he makes the suggestion that while social science is in a position to identify ‘social evils’, it is far less able to identify the basis of the good society See also JUSTICE.
