Abstract: In the book Marx's Concept of Nature, Alfred Schmidt re-examines Marx and Engels' views of nature based on the non-ontological characteristics of Marx's materialism, and deeply explains the philosophical propositions about nature, such as the two-way mediation mechanism between nature and society and the concept of material transformation between man and nature. However, his theoretical interpretation fails to fully grasp the essence of the Marxist view of nature, leading to deviations in the overall grasp of Marx's concept of nature: deviations in interpreting the non-ontological characteristics of Marx's materialism, one-sidedness in interpreting Engels' dialectics of nature, a tendency to artificially separate Marx's and Engels' thoughts, and conceptual confusion in constructing the two-way mediation theory. A dialectical analysis of Schmidt's nature thought helps deepen the theoretical understanding of the core of Marxist natural philosophy while adhering to the integrity of the Marxist view of nature.
