of production along class-conscious lines and in accord with the dictates of modem economic evolution is, as already stated before, therefore, an urgent requirement of the hour and on par with generating and accumulating proletarian economic vitality. Class-conscious Socialist organization at the point of production, that is in the industries, however, is essential for a twofold reason and must be accomplished in a definite way.

Such a conception clearly shows the insufficiency and antiquatedness of the craft form of unionism, a form absolutely out of joint with the highly centralized character of capitalist industry. The Historical Materialist, and every scientific Socialist is a Historical Materialist, constructs and adapts his organization to meet the demands of social requirements. He studies economic and social conditions with a view of employing the knowledge gained therefrom to improve the position of the working-class in its fight for emancipation.

The reason for the class character of every form of proletarian organization has been sufficiently underscored and need not be dwelled upon any more. What must now be shown is the necessity for this particular form of unionism: the necessity for Industrial Unionism.
