Note 12. To the Subsection “Theory of Reflection (Copy Theory)”
Engels said, “But if the further question is raised: what then are thought and consciousness, and whence they come, it becomes apparent that they are products of the human brain and that man himself is a product of Nature, which has developed in and along with its environment.” Anti-Dühring (Moscow: Progress Publishers, 1969), 49. Lenin also said, “The mind does not exist independently of the body, … mind is secondary, a function of the brain, a reflection of the external world.” Materialism and Empirio-criticism (Peking: Foreign Language Press, 1972), 95.
