"Socialism has to be built in accordance with general principles. Hence the leading role of the party in the society: the party is the vanguard of the working class, the exponent of its vital interests. Many difficulties are known to have existed in the history of the revolution. For example, after the Great October Revolution, the Mensheviks said they would build a new society without Bolsheviks. The facts have shown, however, that only the Communist party is in a position to build a new society essentially different from the other societies."
