Only by the Logical Tricks of Polylogism Could Etatism Gain a Hold on the Modern Mind; the "Proletarian Philosopher" Dietzgen Taught Thought Is Determined by the Thinker's Class Position

Marx and the Marxians, foremost among them the "proletarian philosopher" Dietzgen, taught that thought is determined by the thinker's class position. What thinking produces is not truth but "ideologies." This word means, in the context of Marxian philosophy, a disguise of the selfish interest of the social class to which the thinking individual is attached. It is therefore useless to discss anything with people of another social class. Ideologies do not need to be refuted by discursive reasoning; they must be unmasked by denouncing the class position, the social background, of their authors. Thus Marxians do not discuss the merits of physical theories; they merely uncover the "bourgeois" origin of the physicists.

The Marxians have resorted to polylogism because they could not refute by logical methods the theories developed by "bourgeois" economics, or the inferences drawn from these theories demonstrating the impracticability of socialism. As they could not rationally demonstrate the soundness of their own ideas or the unsoundness of their adversaries' ideas, they have denounced the accepted logical methods. The success of this Marxian stratagem was unprecedented. It has rendered proof against any reasonable criticism all the absurdities of Marxian would-be economics and would-be sociology. Only by the logical tricks of polylogism could etatism gain a hold on the modern mind.
