Engels attaches great importance to the ideal and belief education of the masses of workers throughout his life. He believes that the working class, to liberate themselves through the socialist road, must be educated in their ideals and beliefs so that they can be united into a class to fight for the liberation of the proletariat and all mankind. He also believes that,to realize socialism from its theory to reality, it is also necessary to cultivate communists who believe in communism theories and have practical power through the ideal and belief education. Moreover, in the practice of the ideal and belief education, Engels thinks it is necessary to combine ideological and political education with revolutionary practice education, to combine promoting Marxism with criticizing non-socialism trends, as well as to combine the recognition of the role of the proletarian leaders with the opposition to the cult of personality.
