Mao's Critique of Empiricism

In chapter three, Mao is discussing dogmatism. He says that the reason the dogmatist and empiricist comrades in China have made mistakes lies precisely in their subjectivist one-sided way of looking at things. In on practice, I think Mao really explains what his problem with epistemological possessivism is. It completely ignores the role of rationality and reason on the one hand, and it substitutes a subjective understanding of the world.
