Political culture, the accumulated influence of political psychology,plays an important role in justifying the political rule.It is the end result and spiritual sublimation of the transformation from political thought system to political ideology, and then to political psychology.The author points out that the class nature of political culture is often embodied in its social nature.Several forms of political cultures have existed throughout the human history.They are political cultures of the slave society,the feudal society,and the capitalist society.No doubt,construction of the socialist culture is by no meaus an easy job.
