Abstract: In Economic and Philosophical Manuscripts of 1844, by criticising the "rough communism" and "political communism", Marx thought that communism was active sublation on private property, a real return of human nature, and really solved contradictions between man and nature and the interpersonal conflicts. Although Marx's communist thought was not mature enough, it analyzed objectively the communist ideology, which provided the theoretical basis for the development of Marx's communist ideology, and had the important contemporary value that helped us hold the right attitude towards private property for the primary stage of socialism in our country, ensure development achievements shared by the people, realize the harmony of human and nature, and promote the all-round development of human beings constantly.
