"As an intellectual enterprise, what came to be called ‘‘modernization theory’’ has many of the same positivist traits as Marxism, with which it self-consciously draws a comparison. Indeed, it could be argued that both constitute a form of ‘‘high modernism’’ that emphasize, in a deterministic form, the unity of all modern development, centered on industry and technology. The Harvard sociologist Talcott Parsons, whose 1937 book The Structure of Social Action inspired most of the postwar modernization theorists, had claimed that an integrated and stable transition to industrial society could only be achieved through changes in political and cultural values. But, unlike Marx, Parsons believed that it was the opportunities for the individual to fit into the structures of society that determined the course of history, not economic developments alone. For Parsons, for MIT’s Daniel Lerner, and for Walt Whitman Rostow – the Harvard professor whose 1960 The Stages of Economic Growth: A Non-Communist Manifesto later became a key text for modernization theory – the form of transition that they described had already taken place, in America. But there were enough ‘‘unsuccessful modernizations’’ – Germany, the Soviet Union, China – to necessitate the search for a grand theory of the road from ‘‘tradition’’ to ‘‘modernity.’’"
