Wow, this must be the most direct criticism of Marxism and its focus on the “proletarian class” I have seen in a long time. Let me quote the closing paragraph of the chapter:
The essence of Marxian philosophy is this: We are right because we are the spokesmen of the rising proletarian class. Discursive reasoning cannot invalidate our teachings, for they are inspired by the supreme power that determines the destiny of mankind. Our adversaries are wrong because they lack the intuition that guides our minds. It is, of course, not their fault that on account of their class affiliation they are not equipped with the genuine proletarian logic and are blinded by ideologies. The unfathomable decrees of history that have elected us have doomed them. The future is ours.
