"The production relations of capitalist society approach more and more the production relations of socialist society. But on the other hand, its political and juridical relations established between capitalist society and socialist society a steadily rising wall. This wall is not overthrown, but is on the contrary strengthened and consolidated by the development of social reforms and the course of democracy. Only the hammer blow of revolution, that is to day, the conquest of political power by the proletariat can break down this wall."

“Lenin's thesis is that the party Central Committee should have the privilege of naming all the local committees of the party. It should have the right to appoint the effective organs of all local bodies from Geneva to Liege, from Tomsk to Irkutsk. It should also have the right to impose on all of them its own ready-made rules of party conduct. It should have the right to rule without appeal on such questions as the dissolution and reconstitution of local organizations. This way, the Central Committee could determine, to suit itself, the composition of the highest party organs. The Central Committee would be the only thinking element in the party. All other groupings would be its executive limbs.”

“I suppose I must be out of sorts to feel everything so deeply. Sometimes, however, it seems to me that i am not really a human being at all, but like a bird or a beast in human form. I feel so much more at home even in a scrap of garden like the one here, an dstill more in the meadows when the grass is humming with bees than - at one of the our party congresses.”

“Plausible as the idea of the United States of Europe as a peace arrangement may seem to some at first glance, it has on closer examination not the least thing in common with the method of thought and the standpoint of social democracy . . . At the present stage of development of the world market and of world economy, the conception of Europe as an isolated economic unit is a sterile concoction of the brain. Europe no more forms a special unit within world economy than does Asia or America.”

“If democracy has become superfluous or annoying to the bourgeoisie, it is on the contrary necessary and indispensable to the working class. It is necessary to the working class because it creates the political forms which will serve the proletariat as fulcrums in its task of transforming bourgeois society. Democracy is indispensable to the working class because only through the exercise of its democratic rights, in the struggle for democracy, can the proletariat become aware of its class interests and its historic task.”

“One Step Forward, Two Steps Backward, written by Lenin, an outstanding member of the Iskra group, is a methodical exposition of the ideas of the ultra-centralist tendency in the Russian movement. The viewpoint presented with incomparable vigor and logic in this book, is that of pitiless centralism.”
