The growth within the capitalist world-economy of the industrial sector of production, the so-called ‘industrial revolution’, was accompanied by a very strong current of thought which denned this change as both a process of organic development and of progress. There were those who considered these economic developments and the concomitant changes in social organization to be some penultimate stage of world development whose final working-out was but a matter of time. These included such diverse thinkers as Saint-Simon, Comte, Hegel, Weber, Durkheim. And then there were the critics, most notably Marx, who argued, if you will, that the nineteenth-century present was only an antepenultimate stage of development, that the capitalist world was to know a cataclysmic political revolution which would then lead in the fullness of time to a final societal form, in this case the classless society.
