You have read and heard that communist theory-the science of communism created in the main by Marx, this doctrine of Marxism-has ceased to be the work of a single socialist of the nineteenth century, even though he was a genius, and that it has become the doctrine of millions and tens of millions of proletarians all over the world, who are applying it in their struggle against capitalism.
Vladimir LeninThe whole struggle of our Party (and of the working class movement in Europe generally) must be directed against opportunism. The latter is not a current of opinion, not a tendency; it (opportunism) has now become the organised tool of the bourgeoisie within the working class movement.
Vladimir LeninBy destroying the peasant economy and driving the peasant from the country to the town, the famine creates a proletariat... Furthermore the famine can and should be a progressive factor not only economically. It will force the peasant to reflect on the bases of the capitalist system, demolish faith in the tsar and tsarism, and consequently in due course make the victory of the revolution easier... Psychologically all this talk about feeding the starving and so on essentially reflects the usual sugary sentimentality of our intelligentsia.
Vladimir LeninThe press should be not only a collective propagandist and a collective agitator, but also a collective organizer of the masses.
