"The Social-Democrat's ideal should not be a trade union secretary. but a tribune of the people, able to react to every manifestation of tyranny and oppression, no matter where it takes place, no matter what stratum or class of the people it affects; he must be able to group all these manifestations into a single picture of police violence and capitalist exploitation; he must be able to take advantage of every petty event in order to explain his socialistic convictions and his Social-Democratic demands to all, in order to explain to all and every the world-historic significance of the struggle for the emancipation of the proletariat."

“It is not our immediate task to “introduce” socialism, but only to bring social production and the distribution of products at once under the control of the Soviets of Workers’ Deputies.”

“The proletariat needs state power, a centralized organisation of force, an organisation of violence, both to crush the resistance of the exploiters and to lead the enormous mass of the population - the peasants, the petty bourgeoisie, and semi-proletarians - in the work of organising a socialist economy.”

“Rectilinearity and one-sidedness, woodenness and petrification, subjectivism and subjective blindness — voilà the epistemological roots of idealism.”
