Wu Jiahua & Yan Peng：The Logical Paths of Engels’ Development of Marxism

　　Theoreticians do not have a full understanding of the original and scientific nature of Engels’ thoughts and they underestimate Engels’ contribution to the development of Marxism, which is largely due to a lack of research on Engels’ thoughts and his diversified ways and logical paths for developing Marxism. By developing Marxism mainly through logical paths such as answering the questions of the times, filling in theoretical gaps, constructing theory systems, standardizing the category of theories, deepening basic theories, revising ideological perceptions, advancing theoretical development, and criticizing erroneous ideas, Engels demonstrated the salient scientific, revolutionary, practical, people-oriented, and developmental nature of Marxism.
