"The bourgeoisie today is a falling class. ... By its imperialist methods of appropriation is destroying the economic structure of the world and human culture generally. Nevertheless, the historical persistence of the bourgeoisie is colossal. It holds to power, and does not wish to abandon it. Thereby it threatens to drag after it into the abyss the whole of society. We are forced to tear it off, to chop it away. The Red Terror is a weapon utilized against a class, doomed to destruction, which does not wish to perish. If the White Terror can only retard the historical rise of the proletariat, the Red Terror hastens the destruction of the bourgeoisie."

“In Stalin each easily finds himself. But Stalin also finds in each one a small part of his own spirit. Stalin is the personification of the bureaucracy. That is the substance of his political personality.”

“The tacit assumption underlying the Lenin-Trotsky theory of dictatorship is this: that the socialist transformation is something for which a readymade formula lies completed in the pocket of the revolutionary party, which needs only to be carried out energetically in practice. This is, unfortunately or – perhaps fortunately – not the case.”

“In January 1928 the working class stood face to face with the shadow of an advancing famine. History knows how to play a spiteful jokes. In that very month, when the kulaks were taking the revolution by the throat, the representatives of the Left Opposition were thrown into prison or banished to different parts of Siberia in punishment for their "panic" before the specter of the kulak.”

“The genuine basis is the petty bourgeoisie. In italy, it has a very large base -- the petty bourgeoisie of the towns and cities, and the peasantry. In Germany, likewise, there is a large base for fascism....”

“Socialist authors promise not only wealth for all, but also happiness in love for everybody, the full physical and spiritual development of each individual, the unfolding of great artistic and scientific talents in all men, etc. Only recently Trotsky stated in one of his writings that in the socialist society "the average human type will rise to the heights of an Aristotle, a Goethe, or a Marx. And above this ridge new peaks will rise.” The socialist paradise will be the kingdom of perfection, populated by completely happy supermen. All socialist literature is full of such nonsense. But it is just this nonsense that wins it the most supporters.”

“For forty-three years of my conscious life I have remained a revolutionist; for forty-two of them I have fought under the banner of Marxism. If I had to begin all over again I would of course try to avoid this or that mistake, but the main course of my life would remain unchanged. I shall die a proletarian revolutionist, a Marxist, a dialectical materialist, and, consequently, an irreconcilable atheist. My faith in the communist future of mankind is not less ardent, indeed it is firmer today, than it was in the days of my youth.”
