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

History has now confronted us with an immediate task which is the most revolutionary of all the immediate tasks confronting the proletariat of any country. The fulfilment of this task, the destruction of the most powerful bulwark, not only of European, but (it may now be said) of Asiatic reaction, would make the Russian proletariat the vanguard of the international revolutionary proletariat. And we have the right to count upon acquiring this honourable title, already earned by our predecessors, the revolutionaries of the seventies, if we succeed in inspiring our movement, which is a thousand times broader and deeper, with the same devoted determination and vigour.

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 reflection of nature in man's thought must be understood not lifelessly but in the eternal process of movement, the arising of contradictions and their solution.
