Abstract: In the work of German Ideology, Marx and Engels have completely criticized “single person” from three links of the Max Shidina’s idealistic basis, the idealist conception of history inevitably caused by his idealism and the abstract man inevitably produced by his idealist conception of history. They have scientifically expounded and proved that the real man in the sight of idealist conception of history can never be fixed as figure of selfishness of abstract man, that selfishness has in a certain degree reflected “existent state of narrow German petty bourgeoisie” and that only collectivism represents future of the real man. The growth of collectivism is not a kind wish, but an objective practice progress. The conclusion of the text is: It is against materialist conception of history to believe everlasting of selfishness and to believe to construct realistic society only by eliminating selfishness through persuasion, not by authoritarian collectivism in the present Chinese economic social developing level.

Key words: Single person and his Possession, selfishness, German Ideology, collectivism
