This bourgeois method of thought, which, being anti-dialectic and anti-materialistic, is opposed to Marxism, has acquired some practical importance in the socialistic movement of countries where by lack of economical development the class-consciousness of the workers is hindered by relics of the narrow-minded views of the class of little producers—as in France and Italy under the name of reformism. In Germany where it could not obtain much practical importance it presented itself mostly as a theoretical struggle against Marxism under the name of revisionism. It combines bourgeois philosophy and anti-capitalist disposition and takes the place formerly occupied by anarchism, and, like anarchism, it again represents in many respects the little bourgeois tendencies in the fight against capitalism. Under these circumstances, a closer study of Dietzgen's philosophical works becomes a necessity.

Marx has disclosed the nature of the social process of production, and its fundamental significance as a lever of social development. But he has not fully explained, by what means the nature of the human mind is involved in this material process. Owing to the great traditional influence exerted by bourgeois thought, this weak spot in Marxism is one of the main reasons for the incomplete and erroneous understanding of Marxian theories. This shortcoming of Marxism is cured by Dietzgen, who made the nature of the mind the special object of his investigations. For this reason, a thorough study of Dietzgen's philosophical writings is an important and indispensable auxiliary for the understanding of the fundamental works of Marx and Engels. Dietzgen's work demonstrates that the proletariat has a mighty weapon not only in proletarian economics, but also in proletarian philosophy. Let us learn to wield these weapons!
