Vladimir Ilyich Lenin,
The Proletarian Revolution and Kautsky the Renegade
(1920)
“ Kautsky admits that the Soviets are a most excellent fighting organization of the proletariat, and that they have a great future before them. But if so, Kautsky's position collapses like a house of cards, or like the Utopia of a petty bourgeois, who believes that one can do without an acute struggle between the proletariat and the bourgeoisie. For a revolution is one continuous, desperate struggle, while the proletariat is the advance guard of all the oppressed, the focus and centre of all aspirations of all the oppressed striving for their liberation. ”
